§ 270
Chapter XVI — Procedure For Assessment
Officers in the performance of their functions. Assessment
Income-tax Act, 2025
When a tax return is filed, it will be processed to calculate the total income or loss after making adjustments for errors, incorrect claims, and inconsistencies. The tax, interest, and fee will be computed based on this calculation. The taxpayer will receive an intimation specifying the amount payable or refund due. Adjustments can be made for things like
- arithmetical errors
- incorrect claims
- inconsistencies with previous years' returns
