FAQ
Q1
What if I donate over the limit?
The excess becomes your self-pay. For example, if your limit is ¥50,000 and you donate ¥60,000, your self-pay becomes ¥12,000.
Q2
One-Stop vs Tax Return - which is better?
The deduction amount is the same. However, One-Stop is limited to 5 municipalities. If filing for medical deductions, you must include Furusato tax.
Q3
Why does my result differ from other sites?
Different estimation methods for social insurance and deductions cause variations. The most accurate is using your withholding slip.
Q4
What if my income fluctuates?
The limit is based on Jan-Dec income. If uncertain, estimate conservatively to avoid over-donating.
