Payroll & Workforce Management in Japan

What running payroll in Japan costs and requires

Japan's national corporate tax rate is 23.2% (reduced to 15% on the first JPY 8 million of taxable income for SMEs with paid-in capital of JPY 100 million or less), but the figure that matters for budgeting is the effective combined rate once local taxes are layered on: national local corporate tax, enterprise tax and inhabitants tax bring the effective rate to approximately 31.5% for large corporations and up to 35.4% for SMEs. Two further changes apply to fiscal years beginning on or after 1 April 2026 — a revised 10.3% national local corporate tax rate and a new 4% "defence capabilities" surcharge on base corporate tax above a JPY 5 million deduction — both of which shift the effective rate mid-transition for companies whose fiscal year does not align with 1 April.

Japan's operational complexity centers on the gap between the statutory minimum required for a company to legally exist and the practical minimum required for a foreign national to be physically present and running it.

What sits on top of gross salary

~15.6% combined (health ~4.925% + welfare pension 9.15% + employment insurance 0.85% + child/childcare support 0.115%), plus 0.81% long-term care insurance for staff aged 40–64 (2026, Tokyo/Kyokai-kenpo) — this is a direct cost the employer budgets on top of gross pay for every hire, not a deduction from it.

• Business Manager visa capital jump — — raised from JPY 5 million to JPY 30 million in October 2025, alongside new management-experience-or-degree, full-time-employee and Japanese-language requirements for the applicant or that employee
• Inkan and notarization formalities — — KK incorporation requires Articles of Incorporation notarized by a notary attached to the Legal Affairs Bureau and a registered company seal (inkan), adding steps with no direct analogue in signature-based jurisdictions
• Qualified Invoice System step-downs — — since October 2023, input tax credits require invoices from registered issuers; the transitional deduction rate for purchases from non-registered suppliers steps down again from 80% to 70% in October 2026
• Layered 2026 tax changes — — the revised 10.3% national local corporate tax rate and a new 4% defence-capabilities surcharge both apply to fiscal years beginning on or after 1 April 2026, changing the effective rate mid-transition for non-calendar-year filers

The statutory floor for Japan

¥1,226/hour in Tokyo (effective October 2025, the highest of Japan's 47 prefectures); national weighted average ¥1,121/hour (2026). Underpaying the statutory floor exposes the employer to fines and back-pay claims, and should be checked against any role before an offer is made — thresholds are typically revised annually.

Standard cycle and documentation

Payroll in Japan runs on a monthly cycle, in arrears. Payslips must itemize gross pay, statutory deductions, and net pay — incomplete or incorrect payslips are exactly what a labour or social security audit checks first, so the format is a compliance requirement, not a formality.

Employer obligations and deadlines

Final corporate income and consumption tax returns due within 2 months of fiscal year-end; a 1-month filing extension is available for corporate income tax with Tax Office approval (consumption tax permits no extension).

Employer registration runs through the Legal Affairs Bureau (Ministry of Justice), typically taking GK: ~7–10 business days once documents are ready (2–4 weeks overall); KK: 14–21 business days due to mandatory notarization (4–8 weeks overall).
