Furusato Nozei: One-Stop Exception vs Tax Return Filing — Which Is Actually Better?
Donations to 5 or fewer municipalities can use the One-Stop Exception, skipping tax returns. However, those claiming medical expenses or mortgage deductions may benefit more from filing a return. Learn which suits your situation.
How Furusato Nozei Works
Furusato Nozei is a system that allows you to donate to municipalities of your choice and receive a tax deduction equal to the donation amount minus 2,000 yen from your income tax and resident tax. With an effective out-of-pocket cost of just 2,000 yen, you also receive gifts from the municipalities you support, making it a popular program.
However, to receive the deduction, you must complete either the "One-Stop Exception" or "Tax Return Filing" procedure. Which method you should choose depends significantly on the number of municipalities you donated to and whether you have other deductions to claim.
There is a cap on the deduction amount, which varies by annual income, family structure, and other deductions. Donations exceeding this cap become entirely out-of-pocket expenses, so careful attention is required.
What Is the One-Stop Exception?
The One-Stop Exception is a convenient system that allows you to receive Furusato Nozei deductions without filing a tax return. You simply fill out the "Application for Special Exception for Donation Tax Credit" sent by the municipality, attach copies of identity verification documents, and return it by mail.
There are two conditions for using this system.
Eligibility for One-Stop Exception
Condition 1: You must be a salaried employee who does not need to file a tax return
This applies to company employees and civil servants whose income taxes are settled through year-end adjustment. Those earning over 20 million yen annually or those with side income exceeding 200,000 yen must file tax returns and cannot use this system.
Condition 2: Donations must be to 5 or fewer municipalities within one year
Multiple donations to the same municipality count as one, but if you donate to 6 or more municipalities, you cannot use the One-Stop Exception and must file a tax return.
One-Stop Exception Deadline
The deadline for submitting the application form is January 10 of the following year (must arrive by that date). If you donate near the end of the year, the application form may arrive late, so timely processing is crucial.
If you miss the deadline, you can still receive the deduction by filing a tax return. Don't panic if you forget to submit the form—just prepare for tax filing instead.
Who Cannot or Should Not Use the One-Stop Exception
If any of the following apply, you cannot use the One-Stop Exception, or filing a tax return would be more advantageous.
Those Required to File Tax Returns
- Salaried employees earning over 20 million yen: Year-end adjustment cannot settle taxes, so tax filing is mandatory
- Those with side income exceeding 200,000 yen: Tax filing is required for non-salary income over 200,000 yen
- Those receiving salary from 2 or more sources: Year-end adjustment works for only one employer, requiring tax filing
- Self-employed individuals/freelancers: Tax filing is already mandatory
- Those with rental income or stock trading profits: Income generation creates filing obligations
Those Claiming Other Deductions
If you're claiming medical expense deductions, mortgage deductions (first year), or casualty loss deductions, you must file a tax return anyway. In such cases, even if you submitted One-Stop Exception forms, the tax return takes priority, and you must include Furusato Nozei donation deductions in your tax return.
If you applied for the One-Stop Exception but forget to include Furusato Nozei donations in your tax return, the deduction will not be applied.
Those Who Donated to 6 or More Municipalities
If you donated to 6 or more municipalities within one year, you are automatically ineligible for the One-Stop Exception and must file a tax return.
One-Stop Exception vs Tax Return Filing Comparison
Here's a table comparing which method to choose.
| Item | One-Stop Exception | Tax Return Filing |
|---|---|---|
| Eligible Persons | Salaried employees not filing tax returns | Everyone |
| Municipality Limit | 5 or fewer | No limit |
| Procedure | Mail application to each municipality | Include all in one tax return |
| Required Documents | Application + ID verification (per donation) | Donation receipts (all municipalities) |
| Deadline | January 10 (must arrive) | February 16 – March 15 |
| Deduction Type | Resident tax only | Income tax + resident tax |
| Using with Other Deductions | Not possible (tax filing takes priority) | All deductions in one filing |
| Effort Required | Mail form for each donation | Complete in one filing |
Deduction Amount Is the Same
The final deduction amount (money back in your pocket) is identical whether you use the One-Stop Exception or file a tax return. With the One-Stop Exception, everything is deducted from resident tax; with tax filing, you get an income tax refund plus resident tax deduction. The total burden reduction is the same.
Understanding Your Furusato Nozei Deduction Cap
There is a cap on deduction amounts, and donations exceeding this become out-of-pocket expenses. The cap is determined by the following factors.
Factors Determining the Cap
- Annual income: Higher income = higher cap
- Family structure: Presence of spouse or dependents
- Other deductions: Mortgage or medical expense deductions lower the cap
- Social insurance premiums: Higher premiums reduce taxable income and the cap
Deduction Cap Estimates by Income (Single/Dual-Income)
| Annual Income | Estimated Cap |
|---|---|
| 3 million yen | ~28,000 yen |
| 4 million yen | ~42,000 yen |
| 5 million yen | ~61,000 yen |
| 6 million yen | ~77,000 yen |
| 7 million yen | ~108,000 yen |
| 8 million yen | ~129,000 yen |
| 10 million yen | ~176,000 yen |
These are rough estimates. For accurate caps, use a simulator.

Recommended Method by Situation
One-Stop Exception Recommended For
- Company employees/civil servants whose taxes are completed through year-end adjustment
- Those donating to 5 or fewer municipalities
- Those not claiming medical expense or mortgage deductions
- Those wanting to avoid tax filing hassle
The One-Stop Exception requires only mailing application forms, making it simple even for those unfamiliar with tax filing.
Tax Return Filing Recommended For
- Those who donated to 6 or more municipalities
- Those claiming medical expense or mortgage deductions
- Those with side income requiring tax filing
- Self-employed individuals/freelancers
- Those who missed the One-Stop Exception deadline
With tax filing, you can consolidate all deductions in one submission, reducing effort when multiple deductions apply. Electronic filing (e-Tax) allows filing from home.
Common Mistakes and Solutions
Mistake 1: Applied for One-Stop but forgot to include Furusato Nozei in tax return
When you file a tax return for medical expenses, the One-Stop Exception becomes automatically invalid. Forgetting to include Furusato Nozei donation deductions in your tax return means you lose the deduction.
Solution: When filing a tax return, always prepare all Furusato Nozei donation receipts and complete the "Donation Deduction" section of the tax return form.
Mistake 2: Missed the application deadline (January 10)
One-Stop Exception applications must arrive by January 10 of the following year. Mail timing may cause missed deadlines.
Solution: If you miss the deadline, don't panic—file a tax return to claim the donation deduction. The tax filing deadline is March 15, so there's still time.
Mistake 3: Donation amount exceeded the deduction cap
Amounts exceeding the cap become entirely out-of-pocket. Some donate large amounts for gifts and end up losing money on undeducted portions.
Solution: Always verify your deduction cap with a simulator before donating. Keep donations slightly below the cap rather than at the limit.
Summary
Whether you choose the One-Stop Exception or tax return filing, the final deduction amount is the same. The decision criteria are "effort" and "presence of other deductions."
- 5 or fewer municipalities, no other deductions → One-Stop Exception is simpler
- Claiming medical expense or mortgage deductions → File tax return to consolidate
- Side income or self-employed → Already filing tax returns, so include Furusato Nozei there
Whichever method you choose, accurately understanding your deduction cap and completing procedures by the deadline is crucial.
