7 common furusato nōzei mistakes (and how to avoid them)

1. Donating over your limit

Anything above your personal limit is simply your own cost. The limit depends on income, household and other deductions — estimate it first and leave a margin.

2. Donating in a family member’s name

The deduction goes to the person who donated. If the income earner should get the deduction, donate in their name, paying with a card in the same name. Spouse-name applications are a classic cause of lost deductions.

3. One-Stop forms missed or incomplete

One form per donation per municipality, arriving by January 10. Missing My Number copies are a frequent defect. If you miss it, switch to a tax return — see how to file the One-Stop Exception.

4. Year-end payment counted as next year

The donation date is in principle the payment completion date. Bank transfers and payment slips can slip into January — at year-end use instant payment (credit card) and check each portal’s cut-off.

5. Donating to 6+ municipalities and expecting One-Stop

One-Stop requires 5 or fewer. At 6 or more, you must file a tax return for all donations.

6. Filing a tax return but forgetting the donations

A tax return voids your One-Stop applications. If you file (e.g. for medical expenses), you must include the donation deduction in the return — otherwise the deduction is lost.

7. Moving without notifying

If your address changes after a One-Stop application, submit a change notification to each municipality by January 10.

Pre-donation checklist

• Limit estimated, with a margin
• Donation and payment in the deduction-receiver’s name
• One-Stop: 5 municipalities max, arrives by Jan 10
• Year-end: instant payment + portal cut-offs
• Filing a return? Include the donations
