US Citizens Working in Japan are REQUIRED to file a US Income Tax Return Every Year!

  • US citizens and green card holders living in Japan have an automatic extension to file their tax returns by June 15.
  • However, if you owe taxes, payments are still due by April 15. You will be charged interest if you pay after April 15 
  • If you cannot file by June 15, you can apply for an automatic extension to file by October 15

I'm David Lewis. I have been helping US residents in Japan with their US tax preparations and problems since 1987.


  • Please e-mail me with any questions regarding your tax return or for a free estimate.
  • I also will take a look at your prior year's tax return for free.
