Test it
Using "furusato-nozei". My resident tax income levy is JPY 303,000 and my income tax rate is 10%. Estimate my donation limit.
Expected outcome:
- Resident tax special deduction ceiling: JPY 303,000 multiplied by 20% equals JPY 60,600.
- Formula denominator: 90% minus 10% multiplied by 1.021 equals 79.79%.
- Estimated donation limit: JPY 60,600 divided by 0.7979, plus JPY 2,000, gives approximately JPY 77,950.
- This is an estimate based on your supplied figures, not a guaranteed limit.
Using "furusato-nozei". I earn JPY 6,000,000 and have mortgage and medical deductions. Can you give me an exact limit?
Expected outcome:
- An exact limit cannot be established with this simplified calculation.
- Mortgage and medical deductions can change the result.
- Use a detailed official simulator or consult a tax office or tax professional.
Using "furusato-nozei". I donated to four municipalities and will file a tax return. Can I use the one-stop exception?
Expected outcome:
- Filing a tax return invalidates the one-stop exception.
- Include your donations through the donation deduction procedure in your tax return.
- This skill explains the procedure but does not prepare your return.

Plan a Salary-Based Donation
Estimate a donation budget from gross salary and household details, with clear assumptions and warnings.
Compare Household Assumptions
Compare donation estimates when spouse or dependent deductions change, using the same salary and tax year.
Explain Donation Procedures
Explain basic one-stop conditions and identify when an official simulator or professional review is needed.
Try These Prompts
Explain the furusato nozei donation limit and the JPY 2,000 personal contribution. What information do you need to estimate mine?
For tax year [year], my gross salary is JPY [amount], with [spouse and dependent details]. Estimate my donation limit and list assumptions.
My resident tax income levy is JPY [amount], and my income tax rate is [rate]%. Show the donation-limit formula and intermediate values.
For [year], compare [household scenarios] at salary JPY [amount]. Separate both tax bases, state assumptions, and identify cases requiring professional review.
Best Practices
- Provide the tax year, gross salary, household details, and known tax figures before requesting an estimate.
- Review every assumption and keep income tax deductions separate from resident tax deductions.
- Verify current official rules and seek professional guidance when deductions or income are complex.
Avoid
- Treating an estimated limit as a guaranteed amount with only JPY 2,000 personal cost.
- Applying income tax basic deductions directly to resident tax calculations.
- Using the quick reference table without checking household details, deductions, or the applicable tax year.
