Tax in Japan: Fundamentals and Practical Q&As on Stock Options

Taxation of Listed Stocks

Tax Rate:

Net gains from stock sales are taxed at 20.315%.

Tax collection methods:

Through withholding at source, or annual tax return filing.

Securities Account Types:

  • Domestic Securities Account: Tax is automatically withheld.
  • Foreign Securities Account: Tax must be paid through annual tax return filing.

Special Considerations for Foreign-Issued Stock Options:

When stocks acquired through foreign-issued stock options are held in foreign securities accounts (common scenario), the capital losses cannot be offset against dividend income nor be carried forward to future tax years.

Note: Generally, use the closing rate on the transaction date (or previous day’s rate if unavailable) published by a major Japanese bank.
