Statutory Filing Documents Related to Payroll
When a company pays salaries to employees in Japan, it is legally required to prepare and submit various statutory filings, including salary payment reports and payroll-related tax documents. These filings directly affect income tax withholding, resident tax assessments, and overall payroll compliance.
For foreign-owned companies operating in Japan, payroll-related compliance can be particularly complex. Differences between Japanese and overseas payroll systems, tax concepts, and reporting timelines often require careful coordination beyond routine payroll calculations.
Our firm provides comprehensive support for payroll-related statutory filings for foreign-owned companies, combining Japanese payroll compliance with international tax and employment expertise.

Role and Importance of Payroll Statutory Filings
Payroll-related statutory filings in Japan primarily consist of three categories.
First, Salary Payment Reports are submitted to local municipalities and form the basis for determining employees’ resident tax liabilities under Japan’s special collection system. These reports are essential for ensuring accurate resident tax withholding in the following fiscal year.
Second, Withholding Tax Statements (Salary Income Withholding Slips) document the total salary paid and income tax withheld for each employee. These statements are provided to employees and are also reported to the tax authorities.
Third, Statutory Filing Summary Reports consolidate payroll withholding data and are submitted to the National Tax Agency. Together, these documents constitute the core payroll compliance filings required under Japanese tax law.
Practical Considerations for Foreign-Invested Companies
Payroll administration in Japan involves more than calculating gross and net salary amounts. Employers must correctly classify and process each component of compensation, including base salary, overtime pay, allowances, and commuting benefits. Certain items, such as commuting allowances, are non-taxable for income tax purposes but are included in the calculation base for social insurance contributions. This distinction often differs from overseas payroll practices and requires careful data management.
In addition, employers must calculate and withhold social insurance contributions—covering health insurance, pension, employment insurance, and workers’ compensation—in accordance with Japanese regulations. These contributions represent both employee deductions and employer-side costs, making accurate payroll processing critical for cost control and compliance.
Income tax withholding must be calculated monthly using statutory tax tables, based on salary amounts and dependent status. Year-end adjustment procedures further reconcile annual tax liabilities and must align with payroll statutory filings.
Resident tax is assessed by local governments based on the prior year’s income and collected through payroll withholding. Delays or errors in salary payment reports may lead to inconsistencies in resident tax assessments and administrative issues with municipalities.
