Payroll in Japan

Payroll in Japan means calculating gross-to-net salary, withholding the three social insurances and national income tax from each employee, paying employer social insurance of about 15.7% on top, issuing payslips and reporting withholding and contributions monthly, then squaring the year off with an annual year-end adjustment. The key local issue is that Japan does not finalise each employee’s income tax in the monthly run; it runs a separate reconciliation called the year-end adjustment, so your monthly maths is provisional until December.

Total employer cost for a ¥6,000,000 annual salary is about ¥6,942,000, around 16% on top of gross.

Our verdict: Fewer than 3 employees and no local entity in Japan: use an EOR at $199 to $600 per employee per month. At 3 or more, opening a GK (roughly $3,000 in setup costs and 8 to 16 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 Japan and want to know what running payroll actually involves. If you want to hire in Japan without becoming the legal employer, an Employer of Record is the faster route.

Payroll in Japan at a Glance

How Does Payroll Work in Japan?

Japanese payroll runs on a steady monthly rhythm. You calculate each employee’s gross salary, strip out their three social insurances and provisional income tax to reach net pay, add the employer social insurance charge on top, then report and pay what is owed to the authorities by the following month.

Two authorities sit behind the numbers. The National Tax Agency, or NTA, collects income tax and is Japan’s equivalent of HMRC or the IRS. The Japan Pension Service runs the pension and health insurance side, and almost everything in Japanese payroll eventually reports to one of these two bodies.

The contributions employees pay are known collectively as shakai hoken, which simply means social insurance. It bundles three separate charges withheld from each payslip: health insurance, employees’ pension, and employment insurance. We unpack each of these in the deductions section below.

Health insurance and the employees’ pension are not charged on the raw salary figure. They are charged on a fixed reference amount called the standard monthly remuneration, a banded grade the authorities set from the employee’s pay when they enrol and review periodically. Each grade has a cap, so very high earners stop accruing contributions above a ceiling.

Income tax has two layers that catch foreign employers out. There is national income tax, collected by the NTA on a progressive scale, and a separate local resident tax (juminzei) of about 10% that funds the prefecture and municipality. The resident tax is billed in arrears on the prior year’s income, so a brand-new hire pays it later, not in their first year.

The piece that makes Japan distinct is the year-end adjustment, called nenmatsu chosei. Through the year you withhold national income tax at provisional rates; in December the employer recalculates each employee’s actual annual tax, applies their deductions and allowances, and settles the difference in the final pay run. Get the monthly withholding or the grade wrong and two things break at once: take-home pay is off, and the year-end adjustment has more to unwind.

What Payroll Taxes Apply in Japan?

Three sets of charges sit on every Japanese salary: the employer’s social insurance, the employee’s three insurances, and income tax in its national and resident layers. They are calculated in a fixed order, and that order is what makes the gross-to-net result.

Employer Payroll Contributions in Japan

The employer pays its own slice of social insurance, roughly 15.7% of pay, broadly matching the employee’s health and pension contributions plus the employer share of employment insurance and a labour-accident premium. This sits on top of gross salary, separate from anything you withhold, and it is the main statutory cost of employing someone in Japan.

For most salaried staff this is your largest add-on above the headline salary. It is why total employer cost runs meaningfully above gross, and why you budget on the loaded figure rather than the offer letter number.

The exact percentage moves with the prefecture and the standard monthly remuneration grade, because health insurance rates are set regionally rather than nationally. Two employees on the same salary in different prefectures can cost you slightly different amounts, which matters when you model a distributed team.

The true cost of employing in Japan

Statutory employer rates; items can apply to different wage bases or carry conditions, so lines do not always sum to the total.

Japan has no statutory 13th-month, holiday or profit-sharing bonus.

Employee Payroll Deductions in Japan

You withhold three social insurances from the employee before income tax. Health insurance funds medical cover at about 4.925% of the standard monthly remuneration; the employees’ pension funds the state pension at 9.15% of that same reference amount; and employment insurance, which funds unemployment benefit, is charged at 0.5% of actual pay.

Together these take roughly 14.7% off gross before any tax is applied. Because health and pension run off the banded grade rather than raw salary, the deduction does not move every time pay nudges up, only when the grade is reviewed.

These are the employee’s contributions, but you are responsible for calculating, withholding and remitting them. If your provider mis-sets the standard monthly remuneration grade, the employee is under or over-deducted every month until it is corrected, and the Japan Pension Service records will not match what you paid in.

Income Tax on Salary in Japan

National income tax runs on a progressive scale from 5% to 45%, collected by the NTA. It is not charged on full salary: an employment-income deduction, a standard allowance that reduces taxable salary before any rate applies, is subtracted first, along with a basic exemption. Only what remains is taxed.

On top of national tax sits the local resident tax (juminzei) of about 10%, which goes to the prefecture and municipality rather than the NTA. The important quirk is timing: resident tax is assessed on the previous year’s income and billed the following June, so a first-year hire has little or no resident tax until year two.

In the worked example below we combine national income tax and the roughly 10% resident tax into a single income tax line, because that is what hits the employee’s annual position. We flag the split in the note so you can see both layers.

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 employee under 40 on Tokyo FY2026 rates (health 9.85% split 50/50 from March 2026 salary; employment insurance FY2026), with health and pension on the standard monthly remuneration (caps not reached). Taxable income = 6,000,000 – 1,640,000 employment-income deduction – 881,400 social insurance – 580,000 basic exemption = 2,898,600, rounded to 2,900,000. The income tax figure combines national income tax (192,500) and a resident tax of about 10% (305,000, computed on the resident-tax base with its unchanged 430,000 basic exemption), excluding the 2.1% reconstruction surtax and the temporary 2025-2026 basic-exemption additions. Employer side ~15.7%: health 4.925% + child & childcare support 0.115% + pension 9.15% + kodomo-kosodate 0.36% + employment insurance 0.85% + workers’ comp ~0.3% (lowest-tier assumption) = 942,000. The employment-income deduction reduces salary before tax (minimum raised to 650,000 yen) and a 580,000 yen basic exemption applies for national tax from the 2025 income year (temporary additions up to 950,000 for lower incomes in 2025-2026 are not modelled).

Read the two bold rows together. A worker on ¥6,000,000 gross takes home ¥4,621,100, while your total cost as employer is ¥6,942,000.

The gap on the employee side comes from the three insurances plus combined income tax; the gap between gross and your cost is the employer social insurance loading. That is the Japan payroll signature: budget on the ¥6,942,000, not the ¥6,000,000, and remember the resident tax slice lands a year later for a fresh hire.

What Payroll Filings Are Required in Japan?

Japan splits its payroll obligations into a steady monthly cycle of withholding and social insurance reporting, then closes the income tax year with a single annual reconciliation. The monthly filings keep the authorities current; the year-end adjustment is where each employee’s tax is finally settled.

What the Monthly Withholding and Social Insurance Report Cover

Each month you report and remit two things. The first is the national income tax withheld from salaries, paid to the NTA. The second is the social insurance contributions, both the employee’s withheld share and your employer share, paid across to the Japan Pension Service.

Because these are filed monthly, they have to reconcile with your actual payroll run and your bank payments. The authorities cross-check them, and a mismatch between what you withheld and what you remitted is a common trigger for a query.

When They Are Due and the Year-End Adjustment

Monthly withholding and contributions are due by the 10th of the month following payment. So tax and social insurance on May salaries are reported and paid by 10 June, leaving your provider a tight window after each run.

The year-end adjustment, nenmatsu chosei, then runs in the final pay period of the year. The employer recalculates each employee’s actual annual income tax against the provisional amounts withheld through the year, applies their deductions and allowances, and refunds or claws back the difference in December pay. For most employees this replaces the need to file a personal tax return.

Who Files Them

The legal obligation sits with the employer. In practice, your payroll provider or accounting firm prepares the monthly withholding, the social insurance reporting and the year-end adjustment on your behalf, or your in-house team files them directly if you run your own Japanese entity.

Either way, confirm in writing who handles the December year-end adjustment, because it is the most error-prone run of the year. 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

Late payment of national withholding tax draws Delinquent Tax (entaizei), charged on the outstanding amount and tiered by how long the payment is overdue. A separate late-payment charge (entaikin) applies to overdue social insurance contributions. Beyond the money, a botched year-end adjustment can leave every affected employee with the wrong annual tax, which is why getting the monthly withholding and the December reconciliation right matters more than the headline penalty suggests.

What Are the Payroll Deadlines in Japan?

Most Japanese payroll obligations land monthly, anchored to that 10th-of-the-following-month payment date. The exception is new-hire enrolment, which is event-driven: a new employee must be registered with the social insurance system within days of starting, not at month end.

Late filing: Late payment of national withholding tax is subject to Delinquent Tax (‘entaizei’). The penalty rate is tiered based on the period of delinquency. For the period from Jan 1, 2024 to Dec 31, 2024, the annual rate was 2.4% for the first two months of delinquency and 8.7% thereafter. Rates are subject to annual change. A separate penalty (‘entaikin’) applies to late social insurance contributions.

What Are the Payslip and Social Insurance Enrolment Rules in Japan?

Japan does not run a single national employee register the way some countries do. Instead, your record obligation is met by enrolling each new hire with the social insurance system and keeping those records current as people join and leave.

The enrolment timing is the rule that catches foreign employers. A new employee must be registered with the Japan Pension Service for health insurance and the employees’ pension within days of their start date, with employment insurance enrolment handled through Hello Work, the public employment office.

On payslips, Japan requires you to issue an itemised payslip to every employee each pay run, showing gross pay, each deduction and net pay, and these are expected in Japanese. Your payroll provider should produce compliant Japanese-language payslips automatically and keep enrolment records in step with every hire and leaver. When you assess a provider, treat enrolment accuracy as seriously as the tax filing: a clean monthly withholding run with a missed pension enrolment still leaves you exposed.

How Much Does Payroll Outsourcing Cost in Japan?

There are two separate numbers in Japanese payroll cost, and confusing them is the most common budgeting mistake. The first is your statutory employer cost, which is the roughly 15.7% employer social insurance loading.

10 of the 15 EOR providers we track publish Japan fees; they range from $199 to $600 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 Japan are not shown.

According to Whichapp’s July 2026 analysis of EOR fees across 40 countries, providers charge $199 to $600 per employee per month in Japan.

10 of the 15 providers we track publish Japan EOR fees. The lowest published rate is $199 per employee per month and the highest is $600.

Contractor management fees in Japan 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 Japan 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 local complexity such as multi-prefecture rate handling and the year-end adjustment workload.

The fee buys the calculation, the monthly withholding and social insurance reporting, payslip production and the year-end adjustment. It does not include the contributions 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 Japan should cover the monthly gross-to-net calculation, withholding of the three insurances and national income tax, monthly reporting to the NTA and the Japan Pension Service, social insurance enrolment, the year-end adjustment, and Japanese-language payslips. Ask for that list in writing. If any of it sits outside the headline fee, you want to know before the first run, not after.

Extra Payroll Costs to Ask About

The gaps tend to appear at the edges of the standard cycle. Ask specifically about the year-end adjustment if it is billed separately, the annual standard monthly remuneration review that resets each grade, bonus runs and their separate social insurance treatment, retirement and severance calculations, and onboarding setup fees for taking on your entity. 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 Japanese kabushiki kaisha (KK) 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 Japan vs EOR in Japan

The line between the two routes is simple: standard payroll assumes you are the legal employer through a Japanese 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 (a kabushiki kaisha (KK)) 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 Japan covers the providers, licensing and costs in full. EOR pricing and provider ranking live there, not on this page.

Best Payroll Providers for Japan

These providers all run payroll in Japan, 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.

3 providers in Whichapp’s independent index cover Japan. The top 3 by composite score:

1. Deel (9.1/10). From $599/month. Best for scale, automation and contractor volume. Runs its own Japan entity.
2. Remote (8.0/10). From $599/month. Best for IP protection and owned-entity purity. Runs its own Japan entity.
3. Rippling (6.4/10). Best for unified IT, HR, and global finance. Runs its own Japan entity.

Rankings come straight from Whichapp’s provider index (coverage 30%, pricing transparency 25%, security and compliance 25%, integration depth 20%); see how we score.

All 3 major EORs we track in Japan run their own local entity there.

Entity model as reported on provider websites, last checked 2026-06-06. An own entity means the provider is the direct legal employer; a partner model adds a third party to the chain.

Deel for Payroll in Japan

Deel is a strong fit if Japan sits alongside other Asia-Pacific hires you want on one platform, with a single dashboard and API across markets. Japan watch-out: confirm whether your Japanese payroll runs on Deel’s own local entity or a partner bureau, and that it owns the year-end adjustment rather than handing it off. Read our Deel review.

Remote for Payroll in Japan

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 and social insurance reporting.

Japan watch-out: confirm Japanese payroll is on Remote’s owned entity rather than a local partner, and that social insurance enrolment with the Japan Pension Service is handled inside the platform. Read our Remote review.

Papaya Global for Payroll in Japan

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

Japan watch-out: Papaya leans on local partners in some markets, so confirm whether your Japanese payroll runs on its own entity or a third-party bureau, and how it handles the prefecture rate variation across a distributed team. Read our Papaya Global review.

Rippling for Payroll in Japan

Rippling appeals when you want payroll wired into the same system as HR, IT and device management, with automated journal entries. Japan watch-out: it is platform-first, so confirm the depth of its Japanese statutory handling, specifically the standard monthly remuneration grading and the year-end adjustment, against what a local specialist would offer. Read our Rippling review.

Multiplier for Payroll in Japan

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

Japan watch-out: confirm it produces Japanese-language statutory payslips and runs the year-end adjustment directly rather than through a reseller, and that its gross-to-net engine models the standard monthly remuneration grades accurately before you anchor any salary offers on it. Read our Multiplier review.

Safeguard Global for Payroll in Japan

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.

Japan watch-out: confirm its Japanese coverage is run in-house rather than subcontracted, and that the service includes social insurance enrolment and the year-end adjustment, not just the monthly calculation. Read our Safeguard Global review.

How to Choose a Payroll Provider in Japan

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

Can They Handle the Monthly Withholding and Year-End Adjustment?

Confirm the provider files monthly withholding to the NTA and runs the year-end adjustment (nenmatsu chosei) in December, reconciling each employee’s actual annual tax against what was withheld. Ask who handles the December run and by when, because it is the most error-prone of the year.

Do They Manage Social Insurance Enrolment?

Check that new-hire enrolment with the Japan Pension Service, and employment insurance enrolment through Hello Work, happen within the statutory window from the start date. A provider that treats enrolment as an afterthought leaves you exposed on the pension and health side.

Can They Model Gross-to-Net Salary Accurately?

Japan’s standard monthly remuneration grades and combined national-plus-resident tax mean gross-to-net is not a simple percentage. A capable provider models it both ways, accounts for the resident tax landing a year later for new hires, and helps you frame offers rather than just processing whatever number you hand over.

How Do They Update for Payroll Law Changes?

Japanese health insurance rates are set by prefecture and revised annually, and the standard monthly remuneration grades reset each year. Ask how the provider tracks these 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 Japan 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 and authority queries are where weak providers show their limits. Ask what support you get during a retirement or severance 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 Japan?

Severance: Japan has no statutory severance or redundancy pay formula based on length of service. Instead, Article 20 of the Labor Standards Act requires employers to provide at least 30 days’ advance notice of dismissal. If an employer dismisses an employee without providing the required notice, they must pay a ‘dismissal notice allowance’ (解雇予告手当, kaiko yokoku teate) equivalent to 30 days of the employee’s average wage. This is a one-time payment in lieu of notice, not a tenure-based severance payment.

Statutory leave: 10 days of paid annual leave plus 16 public holidays a year.

Japan 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 insurance)
• Confirm employee deductions (Health insurance, Employees’ pension, Employment insurance)
• Confirm income tax treatment
• Check who files withholding / nenmatsu chosei and by when
• Confirm social insurance enrolment 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 social insurance enrolment at point eight is the one foreign employers miss most often, because it falls due within days of the start date rather than at month end.

FAQs About Payroll in Japan

Methodology and Disclosure

The social insurance rates, income tax bands, resident tax estimate, filing deadlines and penalty figures on this page come from Whichapp’s Japan statutory dataset, grounded in National Tax Agency income tax and withholding rules and Japan Pension Service social insurance rates for FY2026 (Tokyo), and refreshed as rates change. The worked example is calculated from those rates and reconciles by construction.
