Understanding the New Tax Year Framework Under the Income-tax Act, 2025
Clarification on Income Tax Filing Requirements
The introduction of the Income-tax Act, 2025 has sparked numerous inquiries among taxpayers, especially with the new "Tax Year" concept set to take effect from April 1, 2026. A primary concern has been whether individuals will need to submit two income tax returns: one under the current Assessment Year (AY) system and another under the new Tax Year framework. The Income Tax Department has addressed this uncertainty, confirming that taxpayers will not be required to file two returns for the same income. Although the new legislation replaces the terms "Previous Year" and "Assessment Year" with "Tax Year", the process for filing returns for income earned during FY 2025-26 will remain the same.
According to the Income Tax Department, individuals earning income from April 1, 2025, to March 31, 2026, will continue to file a single income tax return under Assessment Year (AY) 2026-27. The department has clarified that the obligation to file a return under the new Tax Year system will only arise after the completion of the relevant Tax Year. Therefore, taxpayers are not required to submit an additional return simply because the Income-tax Act, 2025 has been enacted. The existing deadlines and filing procedures for various taxpayer categories will still apply for income earned during FY 2025-26.
Which Income Tax Law Applies During the Transition?
Another frequent question pertains to the applicable law for income earned prior to April 1, 2026. The department has clarified that income generated during FY 2025-26 will still be assessed under the provisions of the Income-tax Act, 1961, even if the return is submitted after April 1, 2026, when the new law is in effect. This is due to the fact that the income relates to a financial period that commenced before the Income-tax Act, 2025 came into force. Consequently, taxpayers filing returns for AY 2026-27 will adhere to the regulations of the previous law. However, advance tax responsibilities for income earned from April 1, 2026, onwards will be governed by the provisions of the Income-tax Act, 2025.
When Will the New Tax Year System Commence?
One of the significant changes introduced by the Income-tax Act, 2025 is the establishment of a unified "Tax Year" concept. The government has replaced the previous terminology of "Previous Year" and "Assessment Year" to streamline tax administration. Under the former system, income was earned in one financial year and assessed in the subsequent year, often leading to confusion among taxpayers. The new framework eliminates this distinction by implementing a single Tax Year that typically spans from April 1 to March 31. The inaugural Tax Year will encompass income earned from April 1, 2026, to March 31, 2027. Notably, taxpayers will file their first return under this new framework only after March 31, 2027, in accordance with the relevant filing deadlines. The transition will proceed as follows: Income earned between April 1, 2025, and March 31, 2026, will still be assessed under Assessment Year (AY) 2026–27. However, income earned from April 1, 2026, to March 31, 2027, will no longer be associated with an assessment year and will instead fall under the new Tax Year 2026–27 system.
