Getting a more exact number
- Use this calendar year’s income. The limit for donations made in a year is based on that same year’s income (January to December), which you only know for certain in December. Until then, estimate from last year plus any raise.
- Wait for your withholding slip. Your employer hands out the 源泉徴収票 in December or January. It shows your exact salary and social insurance. If you donate in December, you can use the real figures.
- Stay under the line. Going over costs you real money; going under costs you nothing. We show a safe amount 5% below the estimate.
Your real limit can be lower if you claim a housing-loan deduction, a large medical expense deduction, or have a year with unpaid leave. It can be higher if you have side income or investment income that you declare. In those cases ask your municipal tax office or a tax accountant.
