How Much Does It Cost to Use an Employer of Record (EOR) in South Korea?

TL;DR

• EOR costs in South Korea have two layers: the statutory employer obligations (the same regardless of whether you use an EOR or have your own entity) and the EOR service fee (the cost of outsourcing the compliance infrastructure to manage those obligations).
• Statutory employer costs run approximately 115% to 122% of gross salary — four-insurance contributions across NPS, NHIS, EI, and WCI add roughly 9% to 10% of gross salary, and the mandatory DC retirement plan contribution adds another 8.3% (1/12 of annual wages per month).
• EOR service fees in South Korea are typically priced in one of three ways: a flat monthly fee per employee (KRW 300,000–KRW 600,000), a percentage of gross monthly salary (3%–6%), or a hybrid of the two. Pricing varies by provider, headcount volume, and service scope.
• The total EOR cost per employee in South Korea — combining gross salary, four-insurance, DC retirement, and the EOR service fee — typically lands between 120% and 130% of gross salary for mid-level professional hires.
• Hidden costs matter: setup fees (KRW 0–KRW 1,500,000 per employee), off-boarding fees (KRW 300,000–KRW 800,000 per termination), currency conversion spreads (0.5%–2% above mid-market), and add-on fees for work permit sponsorship (KRW 500,000–KRW 2,000,000 per AEP/E-7 application) can materially inflate the stated fee.
• For a company with 10 Korean employees earning an average of KRW 70,000,000 per year, the total annual EOR cost — including all statutory obligations and EOR fees — lands between KRW 830,000,000 and KRW 870,000,000 versus KRW 700,000,000 gross payroll alone.
• Compared to the full cost of running a Korean Jusik Hoesa (entity), the EOR is cheaper in most scenarios up to 40–60 employees once entity maintenance costs (accounting, audit, legal, payroll administration) are included.
• Team Up provides transparent, flat-fee EOR pricing in South Korea with no setup fees, no hidden conversion spreads, and work permit sponsorship included in the service scope.

The EOR cost in South Korea question has two answers. Most companies looking for one answer get the other. They ask about the EOR service fee and receive a number — KRW 350,000 per employee per month, or 4% of gross salary, or some variant. That number is real. But it is not the full cost of employing someone in Korea through an EOR. The full cost includes statutory employer obligations that apply to every employer in Korea regardless of structure. Most EOR providers quote their fee separately from these obligations, which makes the per-employee cost look lower than it is until the first payroll report arrives.

This article builds the complete cost model. It covers every component of the employer's financial obligation under Korean law, explains the EOR service fee structure and what typical pricing looks like in 2026, identifies the hidden costs that are rarely disclosed in EOR marketing materials, and models the total employer cost for realistic Korean salary levels so your finance team can build an accurate headcount budget before you hire.

The numbers are in Korean Won (KRW). The approximate USD equivalents use a reference rate of KRW 1,350 per USD — current as of the date of publication and subject to exchange rate movement. Salary and cost figures reflect the Seoul professional market for 2025–2026.

Why EOR Costs in South Korea Have Two Layers

Employment in Korea costs what it costs. The Labour Standards Act mandates the employment contract structure. The four-insurance system mandates the contribution rates. The Employee Retirement Benefit Security Act mandates the DC retirement plan. These obligations exist whether you have a Korean Jusik Hoesa or whether you hire through an EOR. An EOR does not reduce these statutory costs — it manages them on your behalf and rolls their administration into its service scope.

The EOR service fee is what you pay for that management. It covers the EOR's legal employer infrastructure: the business registration, four-insurance employer registrations, payroll processing systems, NTS withholding management, year-end tax settlement (연말정산), compliance documentation, and Korean employment counsel access for contract drafting and termination events. The fee is separate from and additional to the statutory employer costs.

Most EOR providers quote only the service fee in their initial pricing. The statutory costs appear on the first payroll report. If your finance team has not modelled both layers, the actual monthly employer cost per Korean employee will be higher than the number in the budget. This article ensures that does not happen.

A useful rule of thumb: if an EOR quotes you a cost that is only slightly above the employee's gross salary, they are quoting only their service fee. They are not quoting the total employer cost. The mandatory Korean employer contributions alone add approximately KRW 540,000 to KRW 800,000 per month to the gross employer cost for a mid-level professional earning KRW 5,000,000 to KRW 7,000,000 per month gross. Ask any EOR to present a full employer cost breakdown — statutory obligations plus fee — before you sign.

Statutory Employer Costs That Apply to Every Korean Employer

The Korean statutory employer cost system has four insurance components plus the mandatory retirement plan contribution. Each has its own calculation base, its own rate, and its own government body. Together, they add between 15% and 18% of gross salary to the employer's direct payroll obligation, before any EOR service fee.

The four-insurance components are: National Pension Service (NPS), National Health Insurance (NHIS), Employment Insurance (EI), and Workers' Compensation Insurance (WCI, administered by COMWEL). The retirement plan contribution under the Employee Retirement Benefit Security Act adds a further 8.33% of annual total wages (1/12 per month). The table below shows the exact 2025–2026 rates.

The Four-Insurance System: NPS, NHIS, EI, and WCI — Exact Rates and Employer Calculations

Insurance Scheme	Governing Body	Employer Rate	Employee Rate	Calculation Base	Monthly Employer Cost (KRW 5M gross)
National Pension (NPS)	National Pension Service	4.5%	4.5%	Standard Monthly Income (SMI)	225,000
National Health Insurance (NHIS)	NHIS Corporation	3.545%	3.545%	Monthly premium income	177,250
NHIS Long-Term Care (LTCI)	NHIS Corporation	0.4591% of NHIS premium	0.4591%	Derived from NHIS premium	~8,100
Employment Insurance (EI)	Ministry of Employment & Labour	0.9% (under 150 employees)	0.9%	Monthly wages	45,000
Workers' Compensation (WCI)	COMWEL	0.7%–18.6% (industry risk)	0%	Monthly wages	35,000 (1.0% mid-range)
Total Four-Insurance (mid-range estimate)		~9.4%–9.9%	~8.9%		~490,000–495,000

Three technical points that affect every cost model:

First, the NPS calculation base is the Standard Monthly Income (SMI), not the gross salary. The SMI must be updated annually by November 30 to reflect salary changes from the preceding April-October period. Until the SMI is updated, NPS contributions are calculated on the prior year's declared income. This creates a common cost miscalculation: post-salary-increase NPS contributions are undercalculated for up to seven months. An EOR with payroll change management tied to NPS SMI obligations corrects this automatically.

Second, the NHIS premium also includes a Long-Term Care Insurance surcharge (장기요양보험료) calculated as a percentage of the NHIS premium rather than as a percentage of wages. It is often omitted from quick-reference cost tables because it is a second-order calculation. Include it: for an employee earning KRW 5,000,000/month, it adds approximately KRW 8,000 to the monthly employer cost.

Third, the WCI rate is set per workplace based on the employer's industry risk classification. Office-based technology and professional services operations typically fall in the 0.7% to 1.0% range. Manufacturing, construction, and logistics carry substantially higher rates. Verify the correct WCI rate for your specific industry classification with the EOR before finalising the cost model.

DC Retirement Plan: The Mandatory Monthly Contribution Most EOR Cost Models Omit

Why the DC Plan Is the Most Commonly Missed Cost Component

The Employee Retirement Benefit Security Act (근로자퇴직급여 보장법) requires every employer in Korea to provide a retirement benefit plan — either a Defined Benefit (DB) or Defined Contribution (DC) plan — for employees who have worked at least one year. The DC plan, which is the standard for foreign-invested companies, requires the employer to contribute at least 1/12 of the employee's annual total wages each month into the employee's individual retirement account (IRP). This is not optional. It is not discretionary. And it applies from the first year of employment — meaning the cost is accruing even before the one-year qualifying period is met.

The DC contribution calculation is based on total annual wages — not just basic salary. Total annual wages include base salary, regular allowances, and any recurring monetary payments. For an employee earning KRW 60,000,000 in annual base salary plus KRW 5,000,000 in annual transport allowance, the DC contribution base is KRW 65,000,000, producing a monthly DC contribution of KRW 541,667.

This figure — approximately KRW 500,000 to KRW 700,000 per month for most professional-level Korean employees — is consistently omitted from EOR quick-reference pricing materials. It adds 8% to 10% of gross salary to the true employer cost. Build it into every Korea headcount model.

A common misunderstanding: the DC retirement plan contribution is not the same as the NPS pension contribution. Both exist simultaneously. NPS is Korea's national public pension scheme — both employer and employee contribute 4.5% of SMI. The DC retirement plan is a separate occupational pension operated through a private financial institution (bank, insurance company, or securities firm). The employer contributes exclusively; the employee's retirement account balance grows from employer contributions plus investment returns. An employee leaving after three years has an NPS entitlement plus a DC retirement account — two separate retirement assets from the same employment.

Labour Standards Act Severance: The Accruing Liability Behind Every Korean Hire

How Severance Accrues and Why It Affects Your Cost Model

Korean Labour Standards Act severance is mandatory for every employee who works more than one year — including those who resign voluntarily. The statutory entitlement is 30 days' average wages for each full year of continuous service. The "average wages" calculation uses the average daily wage over the three months immediately preceding termination, including all regular wages and allowances.

Severance is not a contingent cost that only materialises in termination for cause. It is an accruing obligation from the first year of employment. An employee who works for three years has accrued severance equivalent to approximately three months' average salary — payable regardless of how the employment ends. For cost modelling purposes, this translates to a monthly severance accrual of approximately 8.3% of total annual wages (equivalent to the DC plan contribution rate), because the severance entitlement of 30 days per year is functionally 1/12 of annual average wages per year of service.

Many Korean cost models treat severance as off-balance-sheet — a potential future cost rather than a current accruing obligation. This is the correct accounting treatment for the actual payment (it crystallises at termination), but for headcount planning purposes, the severance accrual should be included in the true employer cost per employee alongside the DC plan contribution. Together, the DC plan and severance accrual add approximately 16% to 17% of gross salary to the fully-loaded employer cost.

Employee Gross Annual Salary (KRW)	Monthly DC Contribution (1/12)	Monthly Severance Accrual (1/12)	Combined Monthly Accrual	% of Gross Monthly Salary
40,000,000	333,333	333,333	666,667	16.7%
60,000,000	500,000	500,000	1,000,000	16.7%
80,000,000	666,667	666,667	1,333,333	16.7%
100,000,000	833,333	833,333	1,666,667	16.7%
120,000,000	1,000,000	1,000,000	2,000,000	16.7%

The 16.7% combined accrual rate is consistent across salary levels because both calculations derive from the same proportional base. Include this in every Korea headcount budget as a monthly per-employee line item, regardless of whether the payment will crystallise in the current fiscal year.

How Korea EOR Pricing Works in 2026

The Three Pricing Structures Used by EOR Providers in Korea

EOR providers in South Korea use three primary pricing structures. Each has advantages and disadvantages depending on your headcount size, salary distribution, and operational requirements.

Structure 1: Flat Monthly Fee Per Employee

The flat fee model charges a fixed amount per employee per month regardless of salary level. In South Korea, flat fees from providers with genuine Korea infrastructure typically range from KRW 300,000 to KRW 600,000 per employee per month (approximately USD 220 to USD 440). Providers at the lower end of this range often exclude certain services — year-end tax settlement, MOEL compliance advisory, or termination management — that providers at the upper end include.

The flat fee model is predictable and easy to budget. It favours clients with higher-salary employees, because the fee represents a smaller percentage of total employer cost as salary increases. For a senior engineer earning KRW 120,000,000 per year (KRW 10,000,000/month), a KRW 450,000 flat fee represents 4.5% of gross monthly salary — reasonable. For a junior employee earning KRW 36,000,000 per year (KRW 3,000,000/month), the same fee represents 15% of gross monthly salary — expensive.

Structure 2: Percentage of Gross Monthly Salary

The percentage model charges a fee calculated as a percentage of the employee's gross monthly salary. In South Korea, EOR percentage fees typically range from 3% to 6% of gross monthly salary. This model is more equitable across salary bands — the fee scales proportionally with the employer's gross cost. But for high-salary hires, the percentage model produces significantly higher absolute fees than a flat-fee competitor.

For a senior software architect earning KRW 150,000,000 per year (KRW 12,500,000/month), a 5% percentage fee is KRW 625,000 per month. A flat-fee provider charging KRW 500,000 per month is cheaper by KRW 125,000 per month — KRW 1,500,000 per year — for that single employee. At scale across 20 senior hires, that difference is KRW 30,000,000 per year. Pricing structure matters more as salary levels rise.

Structure 3: Hybrid Pricing

Some EOR providers use a hybrid model: a base flat fee plus a percentage of salary above a threshold. For example: KRW 300,000 base plus 2% of gross salary above KRW 5,000,000 per month. This model attempts to balance predictability at lower salary levels with proportionality at higher ones. Evaluate hybrid models carefully — the effective fee rate is not always immediately apparent from the formula, and the interaction between the base fee and the percentage component can produce unexpected results at specific salary levels.

EOR Pricing Model	Typical Range (Korea 2026)	Best For	Watch Out For
Flat monthly fee	KRW 300,000–600,000/employee/month	Higher-salary hires, predictable budgets	Expensive for junior employees; check service inclusions
Percentage of gross salary	3%–6% of gross monthly salary	Junior to mid-level salary distributions	High absolute cost for senior hires
Hybrid (base + %)	KRW 200,000–300,000 + 1.5%–3% above threshold	Mixed salary band workforces	Effective rate is not always transparent
Annual flat rate (per employee)	KRW 3,600,000–7,200,000/year	Stable headcount, budget predictability	May not account for mid-year hires pro-rata

Hidden Costs in EOR Pricing: What to Ask Before You Sign Any Korea EOR Contract

Setup Fees

Some EOR providers charge a one-time setup fee per employee for the initial onboarding — covering NPS, NHIS, EI, and WCI registration, employment contract preparation, and payroll system setup. In South Korea, setup fees range from zero to KRW 1,500,000 per employee. For a team of 15 employees, a KRW 1,000,000 setup fee per employee adds KRW 15,000,000 to the first-year cost before any payroll is processed. Ask explicitly: is there a setup fee? Is it per employee or per engagement? Is it refundable if the engagement ends within a defined period?

Off-Boarding and Termination Fees

Termination management in Korea requires severance calculation, LSA procedural compliance, four-insurance de-registration, and final payroll processing — all within a 14-day statutory deadline. Some EOR providers charge a separate off-boarding fee ranging from KRW 300,000 to KRW 800,000 per terminated employee. Others include termination management in the standard monthly fee. The distinction is relevant: if your Korea headcount is likely to fluctuate, termination fees add a variable cost that can materially affect your total EOR cost across the engagement.

Currency Conversion Spreads

If your company invoices in USD or EUR and the EOR manages payroll in KRW, the currency conversion spread is a hidden cost that compounds every month. Providers that convert at the mid-market rate (the interbank rate) add zero spread cost. Providers that apply a proprietary exchange rate, typically 0.5% to 2% above mid-market, add a monthly fee disguised as an exchange rate. On a KRW 100,000,000 monthly payroll, a 1% spread above mid-market costs KRW 1,000,000 per month, KRW 12,000,000 per year — that does not appear in the stated service fee. Ask for the exact exchange rate methodology before signing.

Work Permit and Immigration Fees

E-7 visa sponsorship, ARC (Alien Registration Card) registration, and visa renewal management are not always included in the standard EOR monthly fee. Some providers charge separately for each immigration event: KRW 500,000 to KRW 2,000,000 per E-7 application, plus KRW 300,000 to KRW 500,000 per annual renewal. For a team with several foreign national hires, immigration fees can add KRW 5,000,000 to KRW 15,000,000 or more per year to the effective EOR cost. Clarify upfront whether work permit sponsorship is included and what the per-event pricing is for each immigration document type.

Benefits Administration Fees

Some EOR providers charge separately for administering optional employee benefits — group health insurance top-ups above the NHIS standard, life insurance, meal allowance administration, or commuting allowance processing. In Korea's competitive professional talent market, these benefits are common components of competitive compensation packages. If your EOR charges KRW 50,000 to KRW 150,000 per employee per month for benefits administration above the statutory baseline, that adds KRW 600,000 to KRW 1,800,000 per employee per year to the effective fee.

The cleanest way to evaluate EOR pricing is to ask for a full employer cost illustration for a specific sample employee: a Korean national, earning KRW 70,000,000 per year, standard office industry risk class, no work permit required. Ask the EOR to show every line item: gross salary, NPS, NHIS, LTCI, EI, WCI, DC retirement contribution, EOR service fee, and any additional charges. If the provider cannot produce this illustration within 24 hours, treat it as an operational red flag. A provider with genuine Korea payroll infrastructure has this data at hand.

Complete EOR Cost Model for South Korea: Three Salary Scenarios

The tables below model the total employer cost, statutory obligations plus EOR service fee, for three representative salary levels: a junior professional (KRW 40,000,000/year), a mid-level professional (KRW 70,000,000/year), and a senior professional (KRW 120,000,000/year). The EOR fee used is a flat KRW 450,000/month, a mid-range estimate for a full-service Korea EOR provider with all statutory obligations included in scope.

Scenario A: Junior Professional, KRW 40,000,000 Annual Gross

Cost Component	Monthly (KRW)	Annual (KRW)	% of Gross Salary
Gross Monthly Salary	3,333,333	40,000,000	100.0%
NPS Employer Contribution (4.5% SMI)	150,000	1,800,000	4.5%
NHIS Employer Contribution (3.545%)	118,083	1,417,000	3.5%
NHIS LTCI Surcharge (~0.46% of NHIS)	5,432	65,183	0.16%
Employment Insurance (0.9%)	30,000	360,000	0.9%
Workers' Compensation (1.0% est.)	33,333	400,000	1.0%
DC Retirement Contribution (1/12 annual)	277,778	3,333,333	8.3%
EOR Service Fee (flat rate)	450,000	5,400,000	13.5%
Total Monthly Employer Cost	4,397,959	52,775,516	131.9%

Scenario B: Mid-Level Professional — KRW 70,000,000 Annual Gross

Cost Component	Monthly (KRW)	Annual (KRW)	% of Gross Salary
Gross Monthly Salary	5,833,333	70,000,000	100.0%
NPS Employer Contribution (4.5% SMI)	262,500	3,150,000	4.5%
NHIS Employer Contribution (3.545%)	206,708	2,480,500	3.5%
NHIS LTCI Surcharge (~0.46% of NHIS)	9,509	114,108	0.16%
Employment Insurance (0.9%)	52,500	630,000	0.9%
Workers' Compensation (1.0% est.)	58,333	700,000	1.0%
DC Retirement Contribution (1/12 annual)	486,111	5,833,333	8.3%
EOR Service Fee (flat rate)	450,000	5,400,000	7.7%
Total Monthly Employer Cost	7,358,994	88,307,941	126.2%

Scenario C: Senior Professional — KRW 120,000,000 Annual Gross

Cost Component	Monthly (KRW)	Annual (KRW)	% of Gross Salary
Gross Monthly Salary	10,000,000	120,000,000	100.0%
NPS Employer Contribution (4.5% SMI)	450,000	5,400,000	4.5%
NHIS Employer Contribution (3.545%)	354,500	4,254,000	3.5%
NHIS LTCI Surcharge (~0.46% of NHIS)	16,307	195,684	0.16%
Employment Insurance (0.9%)	90,000	1,080,000	0.9%
Workers' Compensation (1.0% est.)	100,000	1,200,000	1.0%
DC Retirement Contribution (1/12 annual)	833,333	10,000,000	8.3%
EOR Service Fee (flat rate)	450,000	5,400,000	4.5%
Total Monthly Employer Cost	12,294,140	147,529,684	122.9%

Three observations from these models. First, the EOR service fee as a percentage of total employer cost falls as salary rises, from 13.5% of gross for a junior hire to 4.5% for a senior hire. This is the natural effect of a flat fee against a variable cost base. Second, the DC retirement contribution is consistently the second-largest cost component after gross salary, larger than all four insurance contributions combined. If your cost model omits it, you are understating employer cost by 8.3% across every hire. Third, the total employer cost percentage (130% for junior, 126% for mid-level, 123% for senior) converges toward the low 120s at higher salary levels as the flat EOR fee becomes relatively smaller. Use these three scenarios to bracket your own headcount composition.

EOR Cost vs Entity Cost in South Korea: The Honest Comparison

What the Entity Model Actually Costs Beyond Statutory Obligations

The statutory employer obligations, four-insurance contributions, DC retirement plan, and severance accrual are identical under both models. The cost comparison between EOR and entity is therefore a comparison between the EOR service fee and the entity maintenance infrastructure cost. The entity maintenance infrastructure includes: Korean accounting and tax compliance services (KRW 12,000,000 to KRW 30,000,000 per year for a small subsidiary); payroll processing and four-insurance filing services if not managed in-house (KRW 10,000,000 to KRW 20,000,000 per year); Korean employment counsel retainer for LSA compliance and NLRC advisory (KRW 12,000,000 to KRW 24,000,000 per year); registered address or office lease (KRW 12,000,000 to KRW 60,000,000 per year, depending on Seoul district); and corporate bank maintenance fees (minimal but real).

At 10 employees, the entity maintenance infrastructure typically costs KRW 46,000,000 to KRW 134,000,000 per year. The EOR service fee for 10 employees at KRW 450,000/month is KRW 54,000,000 per year. The entity is not cheaper at 10 employees; in most scenarios, it is more expensive when all infrastructure costs are included. The crossover point where the entity becomes cheaper than the EOR is typically 40 to 60 employees, depending on the specific entity maintenance cost structure.

Headcount	EOR Annual Fee (KRW 450K/month flat)	Entity Annual Infrastructure Cost (Mid-Estimate)	More Cost-Efficient Structure
5 employees	KRW 27,000,000	KRW 46,000,000–80,000,000	EOR
10 employees	KRW 54,000,000	KRW 46,000,000–100,000,000	EOR (or close)
20 employees	KRW 108,000,000	KRW 50,000,000–110,000,000	Approaching crossover
30 employees	KRW 162,000,000	KRW 55,000,000–120,000,000	Entity at scale
50 employees	KRW 270,000,000	KRW 60,000,000–130,000,000	Entity clearly

Entity infrastructure cost estimates above assume a standard Seoul office-based professional services operation. Manufacturing, logistics, and regulated industry operations carry materially higher compliance overhead — local industry-specific advisors, higher WCI rates, and additional MOEL compliance obligations — that would shift the crossover point toward higher headcount. For operations with non-standard compliance requirements, the EOR cost advantage extends further than these estimates suggest.

What EOR Pricing Should Include in South Korea: The Non-Negotiable List

Not all EOR fees cover the same scope. A competitive Korea EOR service at any price point should include the following without add-on charges. If any of these are presented as optional extras, price them separately and include them in your total cost comparison.

• Labour Standards Act-compliant employment contract drafting and execution, including probationary period provisions, working hours under the 52-hour cap, and mandatory benefit specifications.
• Four insurance employer registrations, NPS, NHIS, EI, and WCI, completed before the employee's start date. De-registration at the end of employment is included.
• Monthly payroll processing with individual income tax withholding under the NTS schedule and correctly formatted Korean payslips issued each pay period.
• Annual year-end tax settlement (연말정산), employee deduction receipt collection, withholding recalculation, NTS reporting, and February payslip adjustment for over- or under-withheld amounts.
• DC retirement plan establishment and monthly contribution remittance, employer contributions of 1/12 of annual wages per month to a Korea-licensed IRP provider.
• NPS standard monthly income (SMI) annual update in November, ensuring contribution calculations reflect current salary levels.
• LSA severance calculation and payment management at termination, average wage calculation over the preceding three months, 14-day payment deadline compliance, and final payroll processing.
• Four insurance de-registrations at termination, NPS, NHIS, EI, and COMWEL de-registrations completed before the termination effective date.
• MOEL regulatory correspondence management, responding to inspection notices, NLRC preliminary inquiries, and NPS/NHIS contribution audits in Korean.
• Employment record retention, payslips, employment contracts, contribution records, and payroll reports maintained for the statutory retention period (minimum five years for most employment records in Korea).

Work Permit Costs: E-7 Visa Sponsorship Through an EOR in South Korea

What E-7 Visa Sponsorship Costs Through an EOR

Foreign nationals working in professional roles in South Korea typically require an E-7 Specially Designated Activities Visa. The EOR, as the registered Korean employer, can act as the sponsoring employer for E-7 applications. The cost of E-7 visa sponsorship through an EOR has three components: government filing fees, EOR immigration services fees, and any legal counsel fees for complex applications.

Cost Component	Typical Cost (KRW)	Notes
E-7 application government fee	70,000–130,000	Ministry of Justice fee; varies by visa term
ARC (Alien Registration Card) fee	30,000	Immigration office — paid once on entry
EOR immigration services fee (initial)	500,000–2,000,000	Varies by provider and complexity
E-7 annual renewal (government fee)	70,000–130,000	Same as the initial government fee
EOR renewal management fee	300,000–800,000	If charged separately from the standard fee
Labour Market Test (LMT) documentation support	200,000–500,000	Sometimes included; sometimes add-on
Dependent visa (F-3) application support	100,000–400,000	Per dependent; if applicable

For a team with five foreign national hires requiring E-7 visas, the first-year immigration cost — government fees plus EOR sponsorship fees — typically runs KRW 3,500,000 to KRW 11,500,000. In subsequent years, renewal costs are lower: government fees plus EOR renewal management fees for five employees typically run KRW 2,000,000 to KRW 5,000,000 annually. Ask your EOR whether E-7 sponsorship and renewal management are included in the standard monthly fee before assuming they are.

How EOR Costs Scale in South Korea: From 1 Employee to 50

Volume Discounts and Pricing Tiers

Most EOR providers in South Korea offer volume-based pricing — lower per-employee fees as headcount grows. The thresholds and discount structures vary by provider, but a typical tiering looks like: KRW 550,000 per employee per month for 1–5 employees; KRW 450,000 for 6–15 employees; KRW 380,000 for 16–30 employees; KRW 320,000 for 31–50 employees. At 50 employees, a provider offering tiered flat fees might charge KRW 16,000,000 per month in total EOR fees — KRW 192,000,000 per year — versus a flat-rate provider at KRW 550,000 charging KRW 27,500,000 per month.

This volume discount structure is why the EOR vs entity cost crossover point is not a fixed number. If your EOR provider's volume pricing reduces the per-employee fee significantly at 30+ employees, the crossover point with entity costs shifts outward — the EOR remains cost-competitive at higher headcount than the flat-rate model suggests. Evaluate volume pricing tiers explicitly when modelling headcount scenarios above 20 employees.

The True Cost of Scaling a Korea EOR Team

At small headcount (1–10 employees), the EOR service fee is the dominant variable infrastructure cost. The statutory obligations are fixed by law and scale linearly with headcount. At medium headcount (10–30 employees), the EOR service fee begins to feel like a material annual expenditure — KRW 54,000,000 to KRW 162,000,000 — and the comparison with entity maintenance infrastructure becomes sharper. At 30–50 employees, the entity becomes cost-competitive and often more appropriate from a strategic presence perspective. The scaling analysis below models total EOR service fees only (not statutory costs) across headcount levels using tiered pricing.

Headcount	EOR Fee Per Employee/Month	Total Monthly EOR Fee	Total Annual EOR Fee	Annual Fee per USD (est.)
1–5 employees	KRW 550,000	KRW 2,750,000	KRW 33,000,000	~USD 24,400
6–10 employees	KRW 450,000	KRW 4,500,000	KRW 54,000,000	~USD 40,000
11–20 employees	KRW 400,000	KRW 8,000,000	KRW 96,000,000	~USD 71,100
21–30 employees	KRW 360,000	KRW 10,800,000	KRW 129,600,000	~USD 96,000
31–50 employees	KRW 320,000	KRW 16,000,000	KRW 192,000,000	~USD 142,200

How Team Up Prices EOR Services in South Korea

Team Up provides flat-fee EOR pricing for South Korea operations with full statutory obligation management included in the service scope. Our pricing model is designed for finance teams that need a complete employer cost picture — not a partial fee quote that requires independent statutory cost modelling.

• Transparent flat-fee pricing: Our Korea EOR fee is a fixed monthly amount per employee — no percentage of salary, no variable components, no surprises in the payroll report. Volume tiers apply as headcount grows.
• No setup fees: Employee onboarding — four-insurance registration, employment contract preparation, payroll system setup — is included in the monthly service fee from the first month of employment.
• No off-boarding fees: Termination management — LSA severance calculation, four-insurance de-registration, final payroll processing, 14-day payment coordination — is included in the standard service scope.
• Mid-market currency conversion: We convert at the interbank mid-market rate. No proprietary spread above mid-market applied to client invoices.
• Year-end tax settlement included: The January 연말정산 process — employee communication, deduction collection, withholding recalculation, NTS reporting — is managed as part of the annual compliance cycle, not billed as an add-on.
• DC retirement plan management included: Korea-licensed IRP provider selection, monthly contribution remittance, and retirement benefit payment at termination are all included in the standard service fee.
• NPS SMI update management included: Annual November SMI update is managed proactively as a scheduled compliance event, not triggered only by client notification.
• E-7 visa sponsorship available: Work permit sponsorship and renewal management for foreign national hires are available as part of the Korea service scope. Ask about immigration service pricing during the onboarding discussion.
• Monthly employer cost reporting: Every client receives a monthly breakdown showing gross salary, each four-insurance contribution by scheme, DC retirement contribution, EOR fee, and total employer cost — per employee and in aggregate. No consolidated lump sums.

Final Thoughts

The EOR cost in South Korea is not one number. It is a system of costs — statutory obligations that apply to every Korean employer regardless of structure, a service fee that varies by provider and pricing model, and a set of hidden costs that most initial quotes do not surface. The companies that build accurate Korea headcount budgets are the ones that model all three layers before the first hire, not the ones that receive the first payroll report and discover that the actual per-employee cost is 25% higher than the budget line.

The statutory costs — four insurance contributions at approximately 9% to 10% of gross salary plus DC retirement contributions at 8.3% — are not negotiable. They apply to every employer in Korea equally. The EOR service fee is negotiable in the sense that it varies by provider, by headcount volume, and by service scope. But low EOR fees with narrow service scope often produce higher total costs than comprehensive fees that include year-end settlement, DC plan management, and termination handling without additional charges.

Build your Korea cost model on the complete employer cost. Verify the service fee includes what you need — specifically DC retirement plan management, four-insurance de-registration at termination, and year-end tax settlement. Ask about currency conversion methodology. And make sure any work permit requirements for foreign national hires are priced explicitly before you commit to a provider.

Frequently Asked Questions

Does the EOR fee include the four insurance contributions, or are they charged separately?

It depends entirely on the provider. Some EOR providers include statutory employer contributions in their quoted fee — the single monthly invoice covers gross salary, four-insurance contributions, and the service fee combined. Others quote only the service fee and bill statutory contributions as pass-through costs on a separate line. The second model is not wrong, but it makes the fee look lower than the total employer cost actually is. Always ask: does your quoted fee represent the complete employer cost, or just your service component? Request a full employer cost illustration — gross salary, each insurance scheme, DC retirement, and fee — before committing.

Are Korean EOR costs tax-deductible for my company?

In most jurisdictions, EOR service fees paid to a foreign service provider are deductible as business expenses against corporate income tax, subject to the normal rules for service fee deductibility in your home jurisdiction. The statutory employer contributions (NPS, NHIS, EI, WCI, DC retirement) are employer costs regardless of structure — they would be deductible under the entity model as well. Consult your home-country tax advisor on the specific deductibility treatment in your jurisdiction, particularly regarding any withholding tax obligations that may apply to service fees paid to a Korean EOR.

How does WCI (workers' compensation) rate affect the total EOR cost?

The Workers' Compensation Insurance rate varies by workplace risk classification. Office-based technology and professional services typically fall in the 0.7% to 1.0% range. Manufacturing environments can carry rates of 2% to 5%. High-risk categories (construction, chemical processing) can reach 18.6% — which would add KRW 930,000 per month to the employer cost for an employee earning KRW 5,000,000 per month, compared to KRW 35,000 in a 0.7% office environment. If your Korea operation involves any non-office work environment, verify the WCI risk classification with the EOR before finalising the cost model. The rate is set by COMWEL based on your declared business activity and workplace conditions.

Does the EOR cost include performance bonuses or other variable compensation?

The EOR service fee is typically calculated on gross base salary, not on variable compensation. However, variable compensation — performance bonuses, sales commissions, project bonuses — affects the statutory employer costs in two ways. First, recurring variable payments that form part of the employee's regular wage structure must be included in the DC retirement plan contribution base (total annual wages, not just base salary). Second, significant variable payments in a given month affect the year-end tax settlement calculation because they change the actual annual income against which the withheld tax is reconciled. Ensure your EOR's cost model includes a mechanism for tracking and incorporating variable compensation into the DC contribution and year-end settlement calculations.

How quickly can I get a Korea EOR cost model for my specific headcount?

Any EOR with established Korea payroll infrastructure should be able to produce a full employer cost model — covering gross salary, all four-insurance contributions at the correct 2025-2026 rates, DC retirement contribution, and service fee — within 24 hours of receiving your employee profile (salary, industry, nationality, work permit requirement). If a provider takes longer than 48 hours to produce a specific cost model or cannot break down the statutory and service fee components separately, that is an indication they may not have the Korea-specific operational infrastructure that accurate cost modelling requires. Use the response quality and speed as an early signal of operational capability.

What happens to the DC retirement plan balance if an employee leaves before the one-year qualifying period?

Under the Employee Retirement Benefit Security Act, the DC retirement benefit becomes vested after one year of continuous employment. An employee who leaves before completing one year is not legally entitled to the DC retirement balance — the unvested contributions return to the employer. In practice, however, many EOR providers and Korean employers choose to include a contractual provision for pro-rated retirement benefit payment even for sub-one-year employment, particularly for senior hires where the negotiated package includes this commitment. If your EOR has been contributing to a DC plan account during a short employment period, clarify the disposition of those contributions — whether they revert to the employer or are paid to the employee under a contractual rather than statutory obligation.
