Income Tax & Tax Year 2026-27: A Complete Guide for Taxpayers
the earlier Income-tax Act, 1961, taxpayers commonly dealt with two terms:
-
Previous Year: The period in which income was earned.
-
Assessment Year: The year immediately following the previous year in which that income was assessed.
The Income-tax Act, 2025 introduces a simpler reference called “Tax Year” for income periods governed by the new law.
| Particulars | Earlier terminology | New terminology |
|---|---|---|
| Income period | Previous Year | Tax Year |
| Assessment period | Assessment Year | No separate Assessment Year concept under the new Act |
| Income earned during April 2026–March 2027 | Not applicable under the old terminology for this period | Tax Year 2026-27 |
This change aligns the tax-year reference with the financial year and reduces confusion caused by referring to two different years.
4. Important Difference Between AY 2026-27 and Tax Year 2026-27
This is one of the most important points for taxpayers during the transition.
AY 2026-27 and Tax Year 2026-27 refer to different income periods.
-
AY 2026-27: Relates to income earned from 1 April 2025 to 31 March 2026. The Income-tax Act, 1961 applies.
-
Tax Year 2026-27: Relates to income earned from 1 April 2026 to 31 March 2027. The Income-tax Act, 2025 applies.
Therefore, taxpayers filing a return for AY 2026-27 must follow the applicable provisions and return forms under the earlier Act. Compliance for Tax Year 2026-27 follows the new Act.
Taxpayers should select the correct Act and period when making tax payments or completing other online tax-related procedures.
5. Key Changes Taxpayers Should Understand
