Japan Tax Deskby Sawada Tax Accountant Office

The Japan-side tax desk for accounting firms and investors abroad.

If your client — or you — owns property, a company or income in Japan, the Japanese filings have to be done by a licensed professional in Japan. That is what we do: fixed fees, everything by email, in English, and we never solicit a partner firm's clients.

Run by Taishi Sawada, Licensed Tax Accountant (Zeirishi) and JICPA Associate Member, Osaka. Registration numbers and how to verify them are on the services page.

Who this is for

Two kinds of people write to us. Pick yours.

Accounting firmsOutside Japan

"My client has Japanese property or a Japanese company. Who handles the Japanese return?"

We act as the Japan-side filing partner for independent accounting firms abroad: non-resident and foreign-company returns, tax agent appointments, Japanese company filings, sale and inheritance returns — under your engagement or alongside it, with the documents your client's home-country return needs. And when our own Japanese clients hold assets in your country, we refer them to you.

Owners & investorsLiving outside Japan

"I own — or am about to buy — property in Japan. What do I owe, and who files it?"

Rental income from Japanese property is taxable in Japan whether or not you live here; 20.42% is often withheld from rent and can usually be partly reclaimed; a sale triggers withholding and a return; and a Japanese company must file every year even at a loss. We handle each of these as a separate, fixed-fee service, and we tell you which ownership structure fits your country before you buy.

What Japan taxes when the owner lives abroad

Three numbers worth knowing before you own anything here.

20.42%

Withholding on rent paid by a corporate tenant to a non-resident owner. A refund of the excess over the actual tax is claimed through an annual return.

10.21%

Withholding on a sale by a non-resident, deducted by the buyer from the price in most cases. Settled through a capital-gains return the following year.

¥70,000

Minimum annual local tax for a Japanese company, payable even with no income — one reason a company is not always the right way to hold property.
