"Supporting a spouse" means the spouse has no income. "Dual income" means the spouse does not qualify for the spouse deduction. Children aged 15 or under do not affect the limit.

How the ¥2,000 works

Everything above ¥2,000 of your donation comes back through three channels:

  1. Income-tax refund = (donation − ¥2,000) × your marginal rate × 1.021
    Paid into your bank account in March–May after you file a tax return. Not used with the one-stop exception.
  2. Resident-tax credit, basic = (donation − ¥2,000) × 10%
  3. Resident-tax credit, special = (donation − ¥2,000) × (90% − marginal rate × 1.021)
    Applied as a lower monthly resident-tax deduction from June of the following year.

Add the three together and you get exactly (donation − ¥2,000). That is why the scheme costs ¥2,000.

The limit is set by your resident tax

The catch is in channel 3: the special credit is capped at 20% of your resident income levy. The donation that exactly uses up that cap is your limit. It therefore depends on resident tax, not on salary alone — the same salary with more dependents, iDeCo contributions or a mortgage tax credit gives a lower limit.

What happens above the limit

Anything over the cap only gets the 10% basic credit and the income-tax refund, so roughly 70–80% of the excess is your own money. Thank-you gifts are capped at 30% of the donation, so going far over the limit is a loss. The slider above shows the exact figure.

Leave a margin. The limit is based on the income of the year you donate in, which is not final until December. If overtime or your bonus falls, the limit falls with it. Donating 80–90% of the estimate is the safe habit.

One-stop exception vs. tax return

If you file a return for any reason — first year of a mortgage credit, medical expenses, side income — the one-stop forms are cancelled automatically. Include the donations in the return or the credit is lost.

Notes for foreign residents

  • Nationality does not matter; paying Japanese resident tax does. You must still be a resident on 1 January of the following year, because that is when the resident tax for the donation year is assessed.
  • If you leave Japan before that date, you will not receive the resident-tax credits, and the donation becomes a plain donation. Do not donate in the year you leave.
  • Gifts are shipped to a Japanese address. Portal sites are in Japanese; the English words to look for are 寄付 (donate), 返礼品 (gift) and ワンストップ特例 (one-stop exception).

FAQ

What is furusato nozei?

A scheme that lets you donate to any municipality, receive a gift worth up to 30% of the donation, and get almost the whole donation back as lower income tax and resident tax. Your net cost is ¥2,000 as long as you stay under your personal limit.

How is the donation limit calculated?

By your resident tax, not your salary directly. The special resident-tax credit is capped at 20% of your resident income levy; the largest donation that stays under that cap is your limit. More dependents, iDeCo contributions or a mortgage tax credit lower it.

Can foreigners use furusato nozei?

Yes — anyone who pays Japanese resident tax. The practical condition is being a resident on 1 January of the following year, when the resident tax for the donation year is billed.

One-stop exception or tax return?

Five or fewer municipalities and no other reason to file: mail the one-stop form to each municipality by 10 January. If you file a return for any reason, include the donations there instead; the one-stop forms are cancelled automatically.
