How to File and Pitfalls of the Furusato Tax One-Stop Special System

The “One-Stop Special System” (ワンストップ特例制度) allows salaried employees to claim Furusato Tax deductions without filing a tax return. We explain the eligibility terms, document requirements, and critical filing deadlines.

Who Can Use the One-Stop System?

  1. Salaried Workers Not Required to File Returns: If you must file a tax return for medical deductions or your first year of a mortgage, you cannot use this system.
  2. Donated to “5 or Fewer Municipalities”: Donating to 6 or more cities forces you to file a tax return (multiple donations to the same city count as one).

Document Checklist

  • One-Stop Special Application Form: Mailed by the recipient city or downloaded online.
  • Copy of Identity Documents: Photocopies of both sides of your My Number Card (or driver’s license + notification card).

Crucial Reminders

  • Deadline is January 10th (Strict): Documents must arrive at the municipal office by Jan 10 of the following year. Missing this forces you to file a tax return.
  • Utilize Online Filing Apps: Many cities support online filings via apps like “IAM,” using your phone to scan your My Number Card, avoiding mail delays.
