## 4. What Happens If You're Late? \[Penalties\]

### 4.1 Failure-to-File Penalty

If you fail to file by the deadline, a **failure-to-file penalty (mushinkoku kasanzei)** is imposed.

| Tax Amount | Penalty Rate |
| --- | --- |
| Up to ¥500,000 | **15%** |
| ¥500,000 - ¥3,000,000 | **20%** |
| Over ¥3,000,000 | **30%** |

**Example**: For a tax amount of ¥1,000,000:

- ¥500,000 × 15% = ¥75,000
- ¥500,000 × 20% = ¥100,000
- **Total: ¥175,000 in penalties**

*Note: If you voluntarily file within 1 month after the deadline and meet certain conditions, the penalty may be reduced to 5%.*

**Source**: [National Tax General Act Article 66](https://elaws.e-gov.go.jp/document?lawid=337AC0000000066)

### 4.2 Delinquency Tax

If you pay late, a **delinquency tax (entaizei)** is charged.

| Period | Rate (2024) |
| --- | --- |
| Day after deadline - 2 months | 2.4% per year |
| After 2 months | 8.7% per year |

**Source**: [NTA "About Delinquency Tax"](https://www.nta.go.jp/taxes/shiraberu/taxanswer/osirase/9205.htm)

### 4.3 Blue Form Special Deduction Reduction

If Blue Form (aoiro shinkoku) filers submit after the deadline, their **special deduction is significantly reduced**.

| Filing Timing | Special Deduction Amount |
| --- | --- |
| On time (e-Tax) | ¥650,000 |
| On time (paper) | ¥550,000 |
| **After deadline** | **¥100,000** |

When the deduction drops from ¥650,000 to ¥100,000, you lose up to **¥550,000** in deductions. At a 20% tax rate, that's about ¥110,000 in extra taxes.

### 4.4 Heavy Additional Tax

In cases of willful tax evasion, a heavier **heavy additional tax (jukasanzei)** is imposed.

| Case | Penalty Rate |
| --- | --- |
| Underreporting | 35% |
| Failure to file | 40% |

## 5. What to Do If You Can't Make It

### 5.1 Cases Where Extensions May Be Granted

Extensions may be granted in the following situations:

| Case | Response |
| --- | --- |
| Natural disasters or unavoidable circumstances | Submit "Application for Extension Due to Disaster" |
| System failures (e-Tax, etc.) | NTA may announce deadline extensions |
| Living abroad with difficulty returning | Appoint a tax agent in Japan |

⚠️ Note

"I was too busy" or "I didn't know" are NOT valid excuses.

### 5.2 Tips for Late Filing

Even if you miss the deadline, it's crucial to **file as soon as possible**.

- Filing within 1 month may reduce the failure-to-file penalty
- Delinquency tax accrues daily, so earlier is better
- Voluntary filing before being contacted results in lighter penalties

## 6. Blue Form Approval Application Deadline

| Case | Application Deadline |
| --- | --- |
| Existing sole proprietor | **March 15** of the year you want to use Blue Form |
| New business (opened after Jan 16) | Within **2 months** of opening |

**Example**: To use Blue Form for 2026 income:
