There are an estimated 50,000 Americans living in Japan.
Living in Japan is an incredible experience for a variety of reasons – the culture, history, landscapes, and cuisine, to name but a few. As an American expatriate living in Japan though, what exactly do you need to know regarding filing US expat (and Japanese) taxes?
The good news is if you are paying income tax in Japan, there are various exclusions and exemptions available to prevent you paying tax on the same income to the IRS too.
US taxes – what you need to know
If you earn over US$10,000 (or $400 if you're self-employed), you have to file IRS form 1040. While taxes are still due by April 15th, expats get an automatic filing extension until June 15th, which can be extended further on request until October 15th.
If you have foreign assets worth over US$200,000 per person, excluding your home if it is owned in your own name, you also have to file form 8938 and declare them.
If you had a total of at least US$10,000 in one or more foreign accounts at any time during the tax year, you also have to file FinCEN form 114, otherwise known as a Foreign Bank Account Report or FBAR.
“In Japan, permanent resident taxpayers are taxed on their worldwide income. Non-resident taxpayers are taxed only on their Japan-sourced income. Non-permanent resident taxpayers are taxed on their Japan-sourced income plus potentially part of their non-Japan-sourced income that is paid in or remitted to Japan.”
The US and Japanese governments share taxpayer info, and Japanese banks pass on US account holders' account info to the IRS, so it's not worth not filing or omitting anything on your return. The penalties for tax evasion for expats are steep to say the least.
If you're a US citizen, green card holder, or US/Japanese dual citizen, and you have been living in Japan but you didn't know you had to file a US tax return, don't worry: there's a program called the IRS Streamlined Procedure that allows you to catch up with your filing without paying any penalties. Don't delay though, in case the IRS comes to you first.
Japanese taxes – what you need to know
The Japanese tax year is the same as the American, however tax returns are due by March 15th.
The Japanese tax authority is called the National Tax Agency. Japanese income tax rates can be found here.
As well as national income tax, Japan also has an inhabitant tax paid to local municipal authorities which is normally 10% of income. There is also a dividend
