1. What gets withheld, and by whom
Under Japanese tax law, a person paying rent to a non-resident landlord must withhold 20.42% (20% income tax + 0.42% reconstruction surtax) and remit it to the tax office by the 10th of the following month.
- Corporate tenant: the tenant withholds directly.
- Individual tenant using the property as their home: exempt — no withholding required.
- Property-management company acting as your agent: most PMs handle withholding, filing and remittance on your behalf.
2. Cash-flow example
Monthly rent: ¥110,000
Withholding (20.42%): −¥22,462
PM fee (7%): −¥7,700
Property tax reserve: −¥10,000
Loan payment: −¥60,000
────────
Monthly cash to you: ¥9,838The ¥22,462 isn't gone — you claim it back at year-end — but until March of the following year, it's Japan's money, not yours.
3. Tax representative (納税管理人)
Every non-resident with Japanese-source income must appoint a tax representative (nōzei-kanri-nin) in Japan. This person receives tax notices and files on your behalf. Options:
- Your PM company (¥3,000–¥10,000/month, often bundled)
- A Japanese tax accountant / zeirishi (¥50,000–¥200,000/year)
- A trusted individual resident in Japan (free, but they must accept the liability)
4. Annual filing (確定申告)
Due March 15 for the prior calendar year. On this return you:
- Declare gross rent and deduct actual expenses: PM fees, property tax, insurance, repairs, loan interest (not principal), and depreciation.
- Compute actual taxable income — typically far less than gross rent.
- Compare to the 20.42% withheld already. Almost always you're owed a refund.
- Refund is wired to your tax representative's Japanese account within 4–8 weeks.
5. Depreciation is the big lever
Japanese buildings depreciate on a fixed statutory schedule:
- Wood: 22 years
- Light-gauge steel: 19 or 27 years by thickness
- Heavy steel: 34 years
- Reinforced concrete (RC / SRC): 47 years
For property older than the statutory life, a shortened schedule applies — often producing 4–8 years of very heavy paper losses that shelter Japanese rental income entirely and, for some jurisdictions, home-country income too. Older wooden houses in particular are used by high-income US investors for exactly this reason (though the 2020 tax reform closed the loss offset for overseas real-estate held by Japanese residents — check current rules for your own status).
6. Tax treaties — what they change
Japan has tax treaties with all target markets (US, UK, Singapore, Hong Kong, Australia, Taiwan). For rental income the treaties do not exempt you from Japanese tax — Japan retains source-country taxing rights. What they do:
- Give you a foreign tax credit in your home country for Japanese tax paid.
- Prevent double taxation of the same income.
- Reduce or eliminate withholding on other income (dividends, interest) — not rent.
Practical takeaway: budget for full Japanese tax on rental income, then claim the credit at home. Don't assume the treaty makes Japan tax go away.
7. Capital gains on sale
When you sell as a non-resident, the buyer withholds 10.21% of the gross sale price (waived if the price is ≤ ¥100M and the buyer will use it as their home). You then file to compute actual capital-gains tax:
- Held > 5 years: 15.315% national + 5% local = 20.315%
- Held ≤ 5 years: 30.63% + 9% = 39.63%
Excess withheld above the true liability comes back as a refund on filing.
8. Modelling this correctly
Every deal you underwrite needs three cash-flow lines: pre-tax NOI, after-withholding cash, and after-refund true income. RE/ANALYSIS runs all three automatically for non-resident owners — try it on a listing you're watching.
