When should you use the One-Stop Special Exception system?

Salaried employees not required to file tax returns who donate to 5 or fewer municipalities per year can use the One-Stop system to have the deduction applied automatically to resident tax.

Does having a mortgage deduction reduce your Furusato Nozei limit?

Yes. If your mortgage deduction significantly offsets your resident tax liability, your effective hometown tax donation ceiling may be reduced accordingly.
