ITR-U is different from a revised return
A revised return is used within the normal revision window. ITR-U under Section 139(8A) is designed for later voluntary correction where additional income or tax is being offered. The law now uses an extended updated-return window, with additional tax increasing the later you file.
Current additional tax bands to check

|---|---|---|
| Within 12 months | 25% | Lowest additional-tax band. |
| 12 to 24 months | 50% | Commonly used for older missed income. |
| 24 to 36 months | 60% | Higher cost under extended window. |
| 36 to 48 months | 70% | Latest band; scrutiny and eligibility must be checked carefully. |
