關於截止日期的重要事項
錯過截止日期會怎樣？
Late-filing penalty (無申告加算税): Filed late on your own before any notice of a tax audit: 5% of the tax due. After an audit notice, but before the tax office would decide your tax: 10% of the tax up to ¥500,000, 15% from ¥500,000 to ¥3M and 25% above ¥3M. After the audit or a tax assessment: 15%, 20% and 30% on the same bands. Nothing is added if you file on your own within one month of the deadline, paid the tax on time and had no such penalty in the past five years.
Late payment interest (延滞税): 2026 rates: 2.8% a year for the first two months after the deadline, then 9.1% a year. Each year has its own rates, published by the NTA, so late payment in 2027 uses the 2027 rates.
Smaller blue return deduction: A return filed after the deadline gets a ¥100,000 blue return deduction instead of ¥550,000 or ¥650,000.
Blue return revocation: Consecutive late filings for 2 years may result in loss of blue return status.
