Japan tax filing deadlines in English

確定申告 runs Feb 16 – Mar 15 for the prior calendar year. Amended returns, departures, and resident-tax billing explained.

Japan's annual income-tax filing window is February 16 through March 15 of the year after the year the income was earned.

  • Income earned in year N → filed between Feb 16 and Mar 15 of year N+1.
  • Direct-debit (振替納税) settlement is around April 20.
  • You can amend a prior return within 5 years via 更正の請求.
  • Resident tax (住民税) is billed separately by your municipality in June of year N+1, based on your filed income for year N.

Departing Japan mid-year

File before departure or appoint a 納税管理人 (tax representative) who will file on your behalf in the normal Feb–Mar window. The app's "Departing" flow includes the dismissal-notification form.
