📚 Understanding Withholding Tax
What is Withholding Tax?
Withholding tax is a system where the payer (client) deducts income tax at the time of payment and remits it to the government. Most fees received by freelancers and sole proprietors in Japan are subject to this withholding.
The withheld amount is reconciled through annual tax returns. If the withheld amount exceeds annual income tax, you receive a refund; if less, you pay the difference.
Withholding Tax Rates (as of 2025)
Withholding tax rates for freelance fees are divided into two tiers at 1 million yen:
- Up to 1 million yen: Fee × 10.21% (10% income tax + 0.21% reconstruction tax)
- Over 1 million yen: (Fee - 1,000,000) × 20.42% + 102,100 yen
Example: For a fee of 1.2 million yen: (1,200,000 - 1,000,000) × 20.42% + 102,100 = 142,940 yen
The reconstruction tax (0.21%/0.42%) continues until December 31, 2037. The 2024 fixed tax reduction does not affect withholding rates and is reconciled at tax return.
Consumption Tax Listing and Net Income
When fee and consumption tax are clearly separated on the invoice, consumption tax is excluded from withholding, increasing net income.
【Example】 Fee of 500,000 yen
- ❌ Combined (550,000 yen incl. tax): Withholding = 550,000 × 10.21% = 56,155 yen → Net 493,845 yen
- ✅ Separate (Fee 500,000 + Tax 50,000): Withholding = 500,000 × 10.21% = 51,050 yen → Net 498,950 yen
Difference: 5,105 yen more net income
Fees Subject to Withholding
The following types of fees are subject to withholding:
- Manuscript fees, lecture fees, design fees
- Fees to lawyers, CPAs, tax accountants, etc.
- Fees to professional athletes, models, entertainers
- Fees to hostesses and companions
- Medical fees from social insurance payment funds
For details, see NTA "No.2792 Fees Subject to Withholding" (Japanese).
Obligations of Payers
Withholding agents (corporations, sole proprietors with employees, etc.) must withhold tax when paying freelancers and remit it by the 10th of the following month.
Failure to withhold may result in non-payment surcharges (10%) and delinquent taxes. Even if the invoice does not specify withholding amount, the payer is responsible for withholding.

FAQ
It combines 10% income tax and 0.21% reconstruction special income tax. The reconstruction tax applies until December 31, 2037. For amounts over 1 million yen, 20.42% (20% + 0.42%) applies to the excess.
10.21% applies to the first 1 million yen, and 20.42% applies to the excess. For example, for 1.2 million yen: (1M x 10.21%) + (200K x 20.42%) = 102,100 + 40,840 = 142,940 yen.
