Best Payroll Software for Japan in 2026

Japan's payroll requires calculating social insurance at ~15% employer share and year-end adjustment (nenmatsu chosei) for all employees.ese payroll (kyuyo keisan) involves social insurance contributions (shakai hoken) at roughly 15% employer share covering health insurance, pension, unemployment, and workers' compensation, plus income tax withholding (gensen choshu) and the year-end tax adjustment (nenmatsu chosei) that reconciles annual tax liability. Employers must also manage the twice-yearly bonus payments that are standard in Japanese employment, calculate overtime premiums at 125-150% of base hourly rate as specified by the Labor Standards Act, and comply with the My Number system for tax identification. This guide covers payroll platforms that process Japanese payroll in JPY and navigate the regulatory framework administered by the National Tax Agency, Japan Pension Service, and local labor bureaus.

Payroll Software for Japan

smarthr

Best for Japanese companies wanting modern cloud payroll and HR in a single platform

SmartHR is Japan's leading cloud HR and payroll platform, used by over 60,000 Japanese companies. The payroll module handles shakai hoken (社会保険) enrollment and contribution calculations, shotoku zei (所得税) income tax withholding using National Tax Agency tables, residence tax deduction coordination with municipal authorities, and the biannual teiki kenkou shindan (定期健康診断) occupational health compliance requirements.

SmartHR automates the nenmatsu chosei (年末調整) year-end tax adjustment process — one of the most labor-intensive payroll tasks in Japan — with employee-facing web forms for declaring dependent exemptions, insurance premium deductions, and housing loan deductions. The platform generates the gensen choshu hyo (源泉徴収票) withholding tax slips required by each employee for their personal tax records.

SmartHR is best suited to Japanese companies with 10 to 5,000 employees that want a modern cloud platform to replace legacy on-premise Japanese payroll software. Its Japanese-language interface and compliance automation for shakai hoken and My Number (個人番号) management make it significantly more practical than adapting a global HR platform for the Japanese market.

Strengths in this market

Automated nenmatsu chosei with employee-facing web declaration for all deduction categories
My Number (個人番号) management with secure collection and storage compliance
Shakai hoken enrollment and monthly contribution calculation across all insurance branches

Limitations to know

Japanese market only — no multi-country payroll for companies with non-Japanese employees
Interface is Japanese-only; foreign-affiliated companies may need bilingual HR support

Japanese Payroll Rules: Shakai Hoken, Gensen Choshu, Nenmatsu Chosei, and Compliance

Shakai hoken (social insurance) covers four insurance categories. Kenko hoken (health insurance) premiums are approximately 9.8-10.5% of standard monthly remuneration, split equally between employer and employee, with rates varying by prefecture and insurance association. Kosei nenkin (employees' pension insurance) is 18.3% split equally. Koyo hoken (unemployment insurance) is 0.6% employee and 0.95% employer for most industries. Rosai hoken (workers' compensation) is employer-only at rates ranging from 0.25% to 8.8% depending on industry risk classification. Total employer social insurance cost is approximately 15-16% of salary.

Gensen choshu (income tax withholding) follows monthly tax tables issued by the National Tax Agency. The withholding amount depends on the employee's monthly salary, number of dependents, and whether they are classified as a Type A (otsu-ran) or Type B (ko-ran) taxpayer. Employers must remit withheld taxes to the tax office by the 10th of the following month. Small employers (fewer than 10 employees) can apply for semi-annual remittance. The year-end adjustment (nenmatsu chosei) in December reconciles the total tax withheld against actual annual liability based on deductions the employee declares.

Juuminzei (residence tax) is deducted from salary in 12 monthly installments from June through May, based on the previous year's income. Municipalities calculate the tax and notify employers of the monthly deduction amounts. The employer simply deducts the specified amount each month and remits it to the municipality. When employees change jobs, the previous employer must complete a kyuyo shiharai hokokusho and the new employer picks up the remaining monthly deductions.

Japanese compensation typically includes base salary (kihon-kyu) plus allowances. Commuting allowances (tsukin teate) are tax-exempt up to JPY 150,000/month for train/bus commuters. Overtime premiums under the Labor Standards Act are: 25% for standard overtime, 35% for work on statutory holidays, 25% additional for late-night work (10pm-5am), and 50% for overtime exceeding 60 hours/month. These premiums are cumulative. The overtime base includes base salary and most allowances but excludes family, commuting, housing, bonus, and certain other allowances.

Pay frequency in Japan is monthly, with most companies paying on the 25th of the month for that month's work. Some companies pay on the 10th, 15th, or last day. Bonuses (shoyo) are typically paid twice yearly — in June/July (natsu no shoyo) and December (fuyu no shoyo) — usually equivalent to 1-3 months of base salary each. Employers must issue gensen choshuhyo (withholding tax certificates) to employees by January 31st and file kyuyo shiharai hokokusho with municipalities by the same deadline. The santei (standard monthly remuneration review) occurs annually in September based on April-June average earnings, and employers must submit the santei todoke to the Japan Pension Service by July 10th.

How to Choose Payroll Software for Japan

Shakai hoken (social insurance) calculations are the core complexity in Japanese payroll. Your software must handle health insurance (kenko hoken), employees' pension insurance (kosei nenkin), unemployment insurance (koyo hoken), and workers' compensation (rosai hoken) — each with different rates, contribution ceilings, and calculation bases. Health insurance and pension rates vary by prefecture and are updated annually. The system must correctly apply the standard monthly remuneration (hyojun houshu getsugaku) tables to determine contribution amounts.

The nenmatsu chosei (year-end tax adjustment) is critical. Japanese employers perform this annual reconciliation in December, adjusting the total tax withheld during the year against the employee's actual annual tax liability based on declared deductions (life insurance, earthquake insurance, dependent exemptions, housing loan deductions). Payroll software must collect employee declarations, calculate the correct annual tax, and process the adjustment in the December or January payroll. Getting this wrong results in employees owing additional tax or receiving incorrect refunds.

Japanese compensation structures typically include a base salary plus multiple allowances — commuting allowance (tsukin teate), housing allowance (jutaku teate), family allowance (kazoku teate), and position allowance (yakushoku teate). Some allowances are taxable, some are partially exempt (commuting allowances up to a limit), and they affect different calculation bases differently. Your payroll software must handle each allowance type with the correct tax and social insurance treatment.

Overtime premium calculations in Japan are more complex than most countries. Standard overtime is 25% premium over base hourly rate. Late-night work (10pm-5am) adds another 25%. Work on statutory holidays carries a 35% premium. When overtime exceeds 60 hours per month, the premium increases to 50%. These premiums stack — late-night overtime on a holiday could be 60%+ premium. Payroll software must calculate these correctly based on actual hours worked.

My Number (individual number system) compliance requires employers to collect, store, and manage employees' 12-digit My Number identifiers for tax and social insurance filings. The software must handle My Number data with appropriate security measures as mandated by the My Number Act. Also verify that the software generates the required year-end reports: gensen choshuhyo (withholding tax slip), kyuyo shiharai hokokusho (salary payment report to municipalities), and hoken ryoritsu santei todoke (social insurance monthly remuneration notification).

What Payroll Experts Say About Running Payroll in Japan

Japanese payroll requires more annual adjustment cycles than most countries. Beyond the monthly payroll processing, employers must handle the santei (September review of standard monthly remuneration based on April-June earnings), the nenmatsu chosei (December year-end tax adjustment), the juuminzei (residence tax) annual update in June when new rates from municipalities take effect, and the shakai hoken rate changes that typically happen in March. Each cycle requires recalculation and adjustment of payroll parameters. Payroll software that automates these annual transitions saves significant time.

The relationship between sharoushi (social insurance and labor consultants) and payroll software is unique to Japan. Many companies, especially those under 100 employees, outsource payroll to a sharoushi firm rather than processing in-house. These licensed consultants handle shakai hoken filings, labor bureau reporting, and payroll tax calculations. When evaluating global payroll platforms for Japan, understanding whether they integrate with sharoushi workflows or replace them entirely is important.

Bonus payments (shoyo) in Japan are not just additional compensation — they have specific tax and social insurance implications. Bonuses are subject to income tax withholding using separate tax tables (not the monthly tables), and social insurance contributions on bonuses are calculated using a special standard bonus amount with annual caps. Payroll software must handle bonus payroll runs separately from regular monthly payroll with the correct tax and contribution calculations.

For foreign companies entering Japan, the initial payroll setup is complicated by the need to register with multiple government agencies — the tax office (zeimusho) for withholding tax, the Japan Pension Service for shakai hoken, the local labor bureau (rodo kijun kantokusho) for labor insurance, and Hello Work for unemployment insurance. An EOR service or a sharoushi firm typically handles these registrations. Once established, companies with 50+ employees often transition to in-house payroll using Japanese or global platforms connected to local processing partners.

Frequently asked questions

Question 1

How does the Japanese nenmatsu chosei (year-end tax adjustment) work and what does payroll software need to do?

The nenmatsu chosei is an annual tax reconciliation that Japanese employers perform in December, adjusting the total income tax withheld throughout the year against each employee's actual annual tax liability. Unlike many countries where employees file their own year-end tax return, Japanese employers perform this reconciliation on behalf of their employees for salaried workers with a single employer. During November-December, employees submit declarations of deductions they are entitled to — life insurance premiums, earthquake insurance, dependent exemptions, housing loan deductions, and others. The payroll system must collect these declarations, calculate the correct annual tax liability using the tax tables, compare it to the total withheld during the year, and process the adjustment in the December or January payroll — either withholding an additional amount if under-withheld, or refunding excess withholding. Getting the nenmatsu chosei wrong means employees receive incorrect refunds or owe additional tax when they file personal returns. ADP Japan handles nenmatsu chosei processing including the employee declaration collection workflow. Platforms using local Japanese payroll partners (sharoushi firms) for nenmatsu chosei must confirm that the partner's system supports all common deduction categories.

Question 2

What is shakai hoken and how are the Japanese social insurance contributions structured?

Shakai hoken (social insurance) covers four categories in Japan. Kenko hoken (health insurance) premiums are approximately 9.8-10.5% of standard monthly remuneration, split equally between employer and employee, with rates varying by prefecture and insurance association. Kosei nenkin (employees' pension insurance) is 18.3% split equally. Koyo hoken (unemployment insurance) is 0.6% employee and 0.95% employer for most industries. Rosai hoken (workers' compensation) is employer-only at rates ranging from 0.25% to 8.8% depending on industry risk classification. Total employer social insurance cost is approximately 15-16% of salary. Critically, shakai hoken contribution rates are calculated on the hyojun hoshu getsugaku (standard monthly remuneration), which is determined from the santei — the annual September review based on April-June average earnings. The santei todoke (notification) must be submitted to the Japan Pension Service by July 10th. Contribution rates for health insurance vary by prefecture — a company with employees in Tokyo pays different rates than one in Osaka. Payroll software must apply the prefecture-specific rate for each employee and update when employees transfer locations.

Question 3

How are Japanese bonus payments (shoyo) taxed, and why must they be processed separately from regular monthly payroll?

Japanese bonuses (shoyo) are subject to different tax and social insurance rules than regular monthly salary, requiring separate payroll processing. For income tax withholding, bonuses use dedicated bonus tax tables issued by the National Tax Agency — not the monthly withholding tables. The calculation references the employee's previous month's salary to determine the applicable withholding rate from the bonus table. Social insurance contributions on bonuses use a special standard bonus amount (hyojun shoyo gaku), rounded down to the nearest ¥1,000, with an annual cumulative cap of ¥5.73 million for pension insurance. Bonuses are typically paid twice yearly — in June/July (natsu no shoyo) and December (fuyu no shoyo) — and usually represent 1-3 months of base salary each payment. These are not optional payments in practice; they are standard components of Japanese compensation packages. Payroll software must run bonus payroll as a distinct payroll event with the correct tax tables and social insurance calculation rules. ADP Japan handles bonus payroll separately from regular monthly payroll with the correct NTA bonus tax tables applied. Platforms relying on sharoushi partners for Japanese payroll must verify that the partner's system handles the bonus-specific calculation rules correctly.

Question 4

What is the Japanese My Number requirement and how does it affect payroll data management?

My Number is Japan's 12-digit individual identification number system, introduced in 2016, which employers must collect, store, and use for tax and social insurance filings. Employers are required to collect My Number from each employee and their dependents (for dependent exemption claims in the nenmatsu chosei). The My Number Act imposes strict data management requirements — employers must have documented processes for how My Number data is collected, stored, used, and disposed of, and must limit access to authorized personnel only. Using My Number for any purpose not specified in the law is prohibited. My Number appears on the gensen choshuhyo (withholding tax certificate), kyuyo shiharai hokokusho (salary payment report to municipalities), and social insurance filing documents. Payroll software must store My Number securely with appropriate access controls and generate compliant output documents with the identifier in the correct fields. Employers who handle My Number data improperly face administrative penalties and public disclosure requirements. Platforms managing Japanese payroll should be able to demonstrate their My Number data handling procedures and system access controls as part of any compliance assessment.

Question 5

What are the juuminzei (residence tax) deduction obligations for Japanese employers, and what triggers changes in the monthly amount?

Juuminzei (residence tax) is deducted from employee salary in 12 monthly installments from June through May, based on the previous calendar year's income. Municipalities calculate each employee's annual residence tax and notify employers of the monthly deduction amounts every May/June, effective for the June payroll. The employer deducts the specified municipality-determined amount each month and remits it to the municipality — the employer has no discretion in the amount. When an employee changes jobs mid-year, the previous employer must complete a kyuyo shiharai hokokusho and transfer the remaining monthly deduction schedule to the new employer. If an employee leaves employment mid-year without a new employer immediately, the remaining installments become payable directly by the individual. The annual update in June means that payroll systems must load new juuminzei amounts per employee from the municipality notifications every year without fail. ADP Japan and Japanese payroll partners (sharoushi firms) handle the annual juuminzei update as a standard part of the June payroll processing cycle. The transition month — June — is when payroll errors related to juuminzei are most common, particularly for mid-year joiners and leavers.
