Payroll in South Korea

Payroll in South Korea means calculating gross-to-net salary, withholding the employee share of the four major insurances and progressive income tax from each employee, paying the employer share of those insurances on top, issuing payslips and filing a monthly withholding return with the National Tax Service by the 10th of the following month. The key local issue is the layering: every salary carries four separate social insurances and an income tax that always picks up an extra 10% local income tax, then the whole year is reconciled in an annual year-end settlement that can leave the employee with a refund or a top-up.

Total employer cost for a ₩ 60,000,000 annual salary is about ₩ 66,400,430, around 11% on top of gross.

Our verdict: Fewer than 2 employees and no local entity in South Korea: use an EOR at $199 to $650 per employee per month. At 2 or more, opening a Yuhan Hoesa (roughly $9,500 in setup costs and 4 to 8 weeks to complete) usually works out cheaper. Already running a local entity: standard payroll outsourcing is the cheaper route.

Use this page if you already have, or plan to set up, a local entity in South Korea and want to know what running payroll actually involves. If you want to hire in South Korea without becoming the legal employer, an Employer of Record is the faster route.

Payroll in South Korea at a Glance

How Does Payroll Work in South Korea?

Korean payroll runs on a steady monthly rhythm. You calculate each employee’s gross salary, strip out their social insurances and income tax to reach net pay, add the employer share of the insurances on top, then report the withheld tax to the tax authority and pay what is owed by a single monthly deadline.

That tax authority is the National Tax Service, or NTS. It is Korea’s equivalent of HMRC or the IRS: the body that collects income tax and runs the year-end reconciliation, and that audits employers when the numbers do not line up. Almost everything tax-related in Korean payroll eventually reports to the NTS.

The social side runs through four separate schemes that employers call the four major insurances. They are National Pension (NPS), National Health Insurance (NHIS), Employment Insurance, and Industrial Accident Compensation Insurance. Three of them are split between employer and employee; the fourth is employer-only.

National Pension is the state retirement scheme, with the employee paying 4.75% on a capped band of income. National Health Insurance funds public healthcare at an employee rate of 3.595%, and it carries a Long-Term Care insurance charge on top calculated as 13.14% of the health premium itself. Employment Insurance funds unemployment benefit at an employee rate of 0.9%.

The fourth scheme, Industrial Accident Compensation Insurance, covers work injuries and is paid entirely by the employer, with no deduction from the employee at all. This split is the first thing to get straight: three insurances come off both sides, but the accident cover is yours alone.

On top of the insurances sits income tax, withheld each month on a progressive scale and always carrying a separate 10% local income tax. Get the insurance caps, the tax bands or the local add-on wrong and two things break at once: the employee’s take-home pay is incorrect, and your monthly withholding return to the NTS no longer matches what you paid.

One feature has no parallel in most countries: the year-end settlement, or yeonmaljeongsan. It is the annual reconciliation in which the tax actually due on a year of salary is compared against the tax withheld month by month, and the difference is refunded to or collected from the employee, covered in detail below.

What Payroll Taxes Apply in South Korea?

Two layers sit on every Korean salary: the four major insurances, and progressive income tax with its 10% local income tax add-on. They are calculated in a fixed order, and that order is what makes the gross-to-net result.

Employer Payroll Contributions in South Korea

The employer pays its own share of the social insurances at roughly 10.67% of gross salary, covering the employer half of National Pension, Health insurance and Employment Insurance, plus the wholly employer-funded Industrial Accident Compensation Insurance. The accident insurance rate varies by industry risk, which is why the employer figure is not a clean mirror of the employee 9.72%.

For most salaried staff this is your main employer add-on, and unlike Western Europe it is moderate rather than heavy. It still means the total cost of a hire runs above the headline salary, so you budget on total employer cost rather than gross.

The accident insurance is the part to confirm with your provider, because its rate is set by sector and is the one piece an off-the-shelf calculator is most likely to estimate. A clerical office and a manufacturing site do not carry the same rate.

Employee Payroll Deductions in South Korea

You withhold three insurances from the employee before income tax: National Pension at 4.75%, National Health Insurance at 3.595%, and Employment Insurance at 0.9%, totalling 9.72% of gross. The Long-Term Care insurance is then added as 13.14% of the health premium, not of salary, so it is a small charge layered onto the health line rather than a separate percentage of pay.

National Pension is withheld on a capped income band, so its contribution stops rising once salary passes the ceiling, while health and employment insurance track gross more closely. These are the employee’s contributions, but you are responsible for calculating, withholding and remitting them.

If your provider miscalculates the National Pension cap or the Long-Term Care add-on, the employee is underpaid or overpaid and your filings will not reconcile against what you paid into the schemes. The cap is the detail most often missed by foreign employers used to flat-rate social charges.

Income Tax on Salary in South Korea

Income tax is withheld on a progressive scale running from 6% to 45% across eight bands as pay rises, applied after an earned-income deduction and the basic personal deduction reduce the taxable base. The rate climbs with salary rather than sitting flat, so higher earners feel a steeper marginal bite.

The detail that surprises newcomers is the local income tax: a further 10% is charged on top of the national income tax figure, not on salary, and it is effectively automatic. A national tax bill of KRW 5,000,000 carries a local income tax of KRW 500,000 on top, so the real income-tax cost is always the national figure plus a tenth again.

Payroll Tax Example: Gross Salary to Net Pay

Here is how the charges stack up for a representative salary. The figures come from the contribution and tax rates above, calculated in the statutory order.

Simplified illustration: Single filer, no dependants, KRW 5,000,000/month (KRW 60,000,000/year) using 2026 rates; NPS 4.75% on the salary (below the KRW 6,590,000 cap so uncapped here) = 2,850,000, NHIS 3.595% = 2,157,000 + LTC 13.14% of premium = 283,430, EI 0.9% = 540,000, employee social total 5,830,430. Income tax after the earned-income deduction (KRW 12,750,000), KRW 1,500,000 basic deduction and deductible NPS at 4.75% (2,850,000): taxable 42,900,000, national tax 5,175,000, plus 10% local income tax = 5,692,500. Employer side matches the employee insurances plus an illustrative ~0.95% for WCI and employment-stability charges (570,000). Employment income first gets a tiered earned-income deduction; a KRW 1,500,000 basic deduction then applies for the taxpayer and each qualifying dependant.

Read the two bold rows together. A worker on KRW 60,000,000 gross takes home roughly KRW 48,477,070, while your total cost as employer is around KRW 66,400,430.

The gap on the employee side is moderate by international standards, and the employer loading is lighter than most of Western Europe. That is the Korean payroll signature: budget on the KRW 66,400,430, not the KRW 60,000,000, and remember the year-end settlement can move the employee’s final tax line either way.

What Payroll Filings Are Required in South Korea?

South Korea splits its payroll reporting into a routine monthly return and a single heavyweight annual reconciliation, which is unusual compared with countries that batch everything the same way each period. The monthly piece is the withholding income tax return; the annual piece is the year-end settlement, and together they are the centre of your compliance year.

What the Monthly Withholding Return Reports

The monthly withholding income tax return is the report you send the NTS each month, declaring the income tax you withheld from every employee’s pay that period. In one submission it tells the NTS what you deducted across the workforce, and it is paired with payment of that withheld tax.

Because it is filed monthly and then trued up annually, it has to reconcile with your actual payroll run and the amounts you remit. The NTS cross-checks the monthly returns against the year-end settlement, and a mismatch is a common trigger for a payroll query.

When the Filings Are Due

The monthly withholding return is due by the 10th of the month following the month of wage payment, alongside payment of the tax. The year-end settlement is then carried out early in the year for the prior year’s salary, reconciling each employee’s full-year tax. The four-insurance acquisition report for a new hire is due by the 15th of the month following the month of hire.

Who Files It

The legal obligation sits with the employer. In practice, your payroll provider files the monthly withholding return and runs the year-end settlement on your behalf, or your in-house team files directly if you run your own Korean entity.

Either way, confirm in writing who handles the year-end settlement, since it is the filing that involves collecting deduction evidence from each employee. The liability for a late or wrong filing stays with you as employer regardless of who does the keying.

What Happens If Payroll Filings Are Wrong

For the withholding tax, a penalty of 3% of the unpaid amount applies, plus a daily late-payment charge of 0.022% of the overdue amount. For the social contributions, a daily late-payment charge of approximately 0.0667% of the overdue amount applies, up to a maximum of 9%. Beyond the money, a year-end settlement that does not reconcile with the monthly returns invites scrutiny of the whole payroll, which is why getting the insurances and tax right the first time matters more than the headline penalty suggests.

What Are the Payroll Deadlines in South Korea?

Most Korean payroll obligations land monthly, anchored to that 10th-of-the-following-month withholding deadline. The exception to watch is the new-hire enrolment: the four-insurance acquisition report is due by the 15th of the month following the month of hire, not at the next pay run.

Late filing: For withholding tax, a penalty of 3% of the unpaid amount applies, plus a daily late payment charge of 0.022%. For social contributions, a daily late payment charge of approximately 0.0667% (1/1500) of the overdue amount is applied, up to a maximum of 9%.

What Payslip and Record Rules Apply in South Korea?

South Korea does not run a single national employee register the way some countries do. Instead, the official record of who you employ is built from the four-insurance acquisition report you file when each person joins, which enrols them into National Pension, Health insurance, Employment Insurance and Industrial Accident Compensation Insurance at once.

The payslip rule is the one not to overlook. Every employee must receive an itemised payslip showing gross pay, each deduction and net pay, issued with every salary payment.

Because the payslip, the monthly withholding return and the eventual year-end settlement all draw on the same calculation, a provider that runs the monthly cycle cleanly usually produces compliant payslips automatically. When you assess a provider, confirm that payslips break out each of the four insurances, the Long-Term Care add-on, national income tax and the 10% local income tax separately, so the year-end settlement reconciles without surprises.

How Much Does Payroll Outsourcing Cost in South Korea?

There are two separate numbers in Korean payroll cost, and confusing them is the most common budgeting mistake. The first is your statutory employer cost, which is mainly the employer share of the four major insurances at roughly 10.67% of gross.

12 of the 16 EOR providers we track publish South Korea fees; they range from $199 to $650 per employee per month.

Published list prices in USD: EOR fees are per employee per month, contractor fees per contractor per month. Providers that publish neither fee for South Korea are not shown.

According to Whichapp’s July 2026 analysis of EOR fees across 40 countries, providers charge $199 to $650 per employee per month in South Korea.

12 of the 16 providers we track publish South Korea EOR fees. The lowest published rate is $199 per employee per month and the highest is $650.

Contractor management fees in South Korea run from $6 to $49 per contractor per month.

The second is the fee you pay a provider to run the payroll for you. They are unrelated, and only the second is negotiable.

Managed Payroll Provider Fees

Managed payroll in South Korea is normally priced per employee per month, and most providers quote rather than publish a rate. The price turns on headcount, on whether you also need accounting or HR support, and on complexity such as the year-end settlement, which is more involved than a routine monthly run.

The fee buys the calculation, the monthly withholding filing, the four-insurance enrolment, payslip production and the year-end settlement. It does not include the taxes and insurances themselves, which you fund on top, so gather two or three quotes before committing.

What Payroll Provider Fees Usually Include

A standard managed payroll fee in South Korea should cover the monthly gross-to-net calculation, withholding of the four insurances and income tax, the monthly NTS return, four-insurance enrolment and itemised payslips. Ask for that list in writing. The year-end settlement in particular should be named in the contract, because it is the one piece that can be quietly priced as an extra.

Extra Payroll Costs to Ask About

The gaps tend to appear at the edges of the standard cycle. Ask specifically about the year-end settlement and collection of employee deduction evidence, severance pay administration, correction filings when something has to be restated, off-cycle or bonus runs, and onboarding setup fees for taking on your payroll. These are the line items that turn a tidy per-head quote into a larger annual number.

When Payroll Outsourcing Becomes Cheaper Than EOR

The choice between running your own payroll and using an EOR is mostly about headcount and how long you plan to stay. An EOR carries a higher monthly fee per person because the provider is the legal employer and absorbs the entity, but it saves you setting one up.

Running your own payroll through a Korean entity is cheaper per head once you are past a handful of employees and committed to staying, because the entity and provider fee spread across more people. In our assessment, the more people you hire and the longer the horizon, the more the economics favour your own entity with outsourced payroll.

Payroll in South Korea vs EOR in South Korea

The line between the two routes is simple: standard payroll assumes you are the legal employer through a Korean entity, while an EOR makes the provider the legal employer so you do not need one.

Use payroll outsourcing if you already have a local entity or are hiring enough people to justify one. Use an EOR if you need to hire before setting up an entity.

If that second case is you, our guide to EOR in South Korea covers the providers, licensing and costs in full. EOR pricing and provider ranking live there, not on this page.

Best Payroll Providers for South Korea

These providers all run payroll in South Korea, but they are built for different situations. Below is where each one fits and the local point to check before you sign. We do not list EOR prices here; for unpriced managed payroll, treat the fee as by quote and confirm it during your shortlist calls.

Deel for Payroll in South Korea

Deel is a strong fit if South Korea sits alongside other Asia-Pacific hires you want on one platform, with a single dashboard and API across markets. South Korea watch-out: confirm it files the monthly NTS withholding return and runs the year-end settlement directly rather than handing it to a partner bureau, and that all four insurances are enrolled inside the platform. Read our Deel review.

Remote for Payroll in South Korea

Remote runs much of its payroll through owned entities, which gives a cleaner compliance chain than a partner-network model. That suits employers who want a direct line of accountability for the monthly withholding return and the four-insurance filings.

South Korea watch-out: confirm Korean payroll is on Remote’s own entity rather than a local partner, and that the year-end settlement and Long-Term Care add-on are handled inside the platform. Read our Remote review.

Papaya Global for Payroll in South Korea

Papaya Global is built for consolidating payroll across many countries with finance-grade reporting and audit trails, so it earns its place when South Korea is one market in a larger stack. Its weakness is the opposite case: for a single Korean entity with no multi-country reporting need, the platform is heavier than the job requires.

South Korea watch-out: Papaya leans on local partners in some markets, so confirm whether your Korean payroll runs on its own engine or a third-party bureau, and how directly it owns the year-end settlement. Read our Papaya Global review.

Rippling for Payroll in South Korea

Rippling appeals when you want payroll wired into the same system as HR, IT and device management, with automated journal entries. South Korea watch-out: it is platform-first, so confirm the depth of its Korean statutory handling, specifically the National Pension cap, the Long-Term Care add-on and the year-end settlement, against what a Korean payroll specialist would offer. Read our Rippling review.

Multiplier for Payroll in South Korea

Multiplier is the value option for multi-country payroll where price predictability matters, which fits smaller Korean teams. The trade-off for that price is depth: in tightly regulated areas it tends to carry less local specialist weight than a Korea-focused bureau.

South Korea watch-out: confirm it files the monthly withholding return and handles the four-insurance enrolment directly rather than through a reseller, and that its gross-to-net engine models the National Pension cap and the 10% local income tax accurately before you anchor any salary offers on it. Read our Multiplier review.

Safeguard Global for Payroll in South Korea

Safeguard Global is a payroll-led specialist rather than an HR platform with payroll bolted on, which appeals when running the payroll correctly is the whole point and you do not need a wider people stack. That focus is also its limit: if you want integrated HR, devices and onboarding in one tool, it does less than Rippling or Deel.

South Korea watch-out: confirm its Korean coverage is run in-house rather than subcontracted, and that the service includes the year-end settlement and NTS correspondence, not just the monthly calculation. Read our Safeguard Global review.

How to Choose a Payroll Provider in South Korea

The questions below separate a provider that genuinely runs Korean payroll from one that resells a local bureau without owning the detail. Ask them before you sign, not after the first run.

Can They File the Monthly Withholding Return and Year-End Settlement?

Confirm the provider submits the monthly withholding income tax return to the NTS by the 10th and runs the annual year-end settlement, reconciling the two each cycle. Ask who collects employee deduction evidence for the settlement and by when.

Do They Manage the Four-Insurance Enrolment?

Check that the provider files the four-insurance acquisition report for each new hire by the statutory deadline and keeps National Pension, Health insurance, Employment Insurance and Industrial Accident Compensation Insurance in step with leavers and pay changes. A provider that treats enrolment as a bolt-on leaves you exposed on the social side.

Can They Model Gross-to-Net Salary Accurately?

A capable provider models gross-to-net both ways, including the National Pension cap, the Long-Term Care add-on and the 10% local income tax, and helps you frame offers rather than just processing whatever number you hand over. Ask to see a sample calculation that shows each of the four insurances broken out.

How Do They Update for Payroll Law Changes?

Korean insurance rates and the National Pension cap are revised periodically, and tax bands shift between years. Ask how the provider tracks NTS and insurance-body changes and how quickly updates reach your payroll runs.

Who Is Liable for Payroll Errors?

The statutory liability stays with you as employer, but the contract should set out what the provider is accountable for if a miscalculation or late filing is their fault. Get the indemnity and correction process in writing.

Can They Support Multi-Country Reporting?

If South Korea is one of several markets, confirm the provider can consolidate reporting across them in a single view, so your finance team is not stitching country files together by hand.

What Support Do They Offer During Terminations or Audits?

Terminations, severance and NTS queries are where weak providers show their limits. Ask what support you get during a termination calculation or an audit, and whether a named contact handles it or you are routed through a ticket queue.

What Does Terminating an Employee Cost in South Korea?

Severance: A statutory minimum of 30 days’ average wage for each year of continuous service.

Statutory leave: 15 days of paid annual leave plus 15 public holidays a year.

South Korea Payroll Checklist Before Hiring

• Confirm whether you need payroll or an EOR
• Check your local entity status
• Model gross-to-net salary for your offers
• Confirm employer contribution rate (employer social insurances)
• Confirm employee deductions (National Pension, Health insurance, Employment insurance)
• Confirm income tax treatment
• Check who files Monthly withholding + year-end settlement and by when
• Confirm Four-insurance acquisition report registration is handled
• Confirm the payslip process
• Check leave, sick pay and termination workflows
• Ask who carries liability for calculation errors
• Confirm provider pricing and any extra fees

Work through this before your first hire. The year-end settlement behind point seven is the one foreign employers underestimate most, because it reconciles a whole year of withholding and can leave employees expecting a refund or a top-up.
