Tax Return Filing for AY 2026-27 and Onward

What are the biggest changes to tax deductions this year, and how do they affect me?

Please remember that AY refers to the Assessment Year in taxation, not to the Accounting Year.

Accounting Year is known as the Financial Year (FY)

Important Changes in the Income Tax Act and Tax Filing

1) New Legislation: The Income Tax Act, 2025, replaces the 1961 Act starting April 1, 2026.

2) Deadline Changes: The filing deadline for non-audit business cases has been extended from July 31 to August 31. For Business entities and audit-mandated firms, the last date is 31st July 2026.

3) Terminology Shift: The new Act is moving toward the term "Tax Year" instead of "Assessment Year" for future filings.

4) Introduction of a simplified New Tax Regime, which will become the default Tax Regime from Financial Year 2026-27. So, if you prefer to be taxed under the Old Regime, you should voluntarily choose it each year. Otherwise, you will be taxed by default under the New Regime (if you forget to choose any particular year) and there will be no trace back to the Old Regime.

There is no change in the deadline for the salaried class. The last date, in their case, is 31st July, 2026 for Financial Year 2025-26.

For the 2025–26 filing season (income you earned in 2025-26), the biggest changes in deductions are higher standard deduction amounts, a much larger SALT (state and local tax) cap, several new or expanded special deductions, and the continued emphasis on the “New” simplified tax regime versus the traditional deduction-heavy regime.

The impact depends on your income level and whether you itemize or use the standard deduction.


For Indian residents, most changes in 2026 are about regime choice and gradual restructuring of deductions, not about big new individual deduction sections.

The new tax regime under section 115BAC continues as the default with simplified slabs and limited deductions, while the old regime with popular deductions like 80C (investments), 80D (health insurance), and 10(10D) (life insurance maturity) remains available if you opt for "Old" instead of the default "New Regime".

For Tax Year 2027-28 (Income earned during 2026-27)

Policy discussions and draft rules for FY 2026–27 point toward consolidating many scattered exemptions and deductions into fewer, broader categories over time, with an explicit push to make more people stay in the new regime. The final decisions are still under process.

Points to Consider While Filing the Return for AY 2026-27 (Income During FY 2025-26)

If you usually claim a lot of deductions (EPF/PPF/ELSS under 80C, medical premiums under 80D, home loan interest under 24(b), etc.), you may still save more by staying with the old regime for now, but you need to compare both regimes each year.


If your salary structure is simple and you don’t invest heavily just for tax saving, you may pay less tax or file more easily in the new regime, since rates are lower and compliance is lighter, even with fewer deductions.


From April 2026, some interest deductions against dividend and mutual fund unit income are being withdrawn, which can slightly increase tax if you borrow to invest.

Revised Return Filing Rules and Deadlines

 Under the current Income Tax Act of India, the revision window for filing a revised Income Tax Return (ITR) under Section 139(5) is as follows: 

1. The Revision Deadline (As of AY 2025-26)

A revised return must be filed within the (below-mentioned) time frame, whichever is earlier: 

• i) December 31st of the relevant Assessment Year (AY). 
• ii) before the completion of the assessment by the Income Tax Department, if the assessment is done earlier. 

Example: 

For the Financial Year (FY) 2024-25, the Assessment Year is 2025-26. The last date to file a revised return is 31 December 2025, provided the assessment is not completed before that. If the assessment is done earlier, say within September 2025, the revised return is to be filed within that period.

Note:

So, if you have missed that opportunity to file a revised return (for any mistakes/omissions), you can no longer file a Revised Return. But, there is a chance to file an Updated Return, which is explained at the bottom of this post.

2. Important Rules for Revision 

• Eligibility: You can revise your return if you discover any error or omission in your original ITR.
• Late Filed Returns: A belated return (filed after the original due date) can also be revised within this timeframe. 
• Multiple Revisions: There are no restrictions on how many times a return can be revised, as long as it is submitted by the deadline. 
• Original Return: The revised return completely replaces the original return. 

What to Do if I Miss the Deadline? 

If the 31st December deadline is missed, you cannot file a regular revised return. 

However, you can file an Updated Return (ITR-U) under Section 139(8A) within 24 months from the end of the relevant assessment year, subject to payment of additional taxes/penalties. 

Future Changes for Revised Return Filing (Budget 2026 Proposal) 

According to recent announcements in the Budget 2026 (for FY 2025-26 onwards), the deadline for filing revised returns is proposed to be extended to 31st March of the Assessment Year (i.e., 12 months after the end of the financial year, instead of 9 months), with a nominal fee applied after 31st December. 

Note: 

For the Financial Year 2024-25, the 31st December 2025 deadline still applies, which already expired on 31st December 2025. So, you should file an Updated Return (not the Revised Return). 

For the Financial Year 2025-26, the deadline allows you to submit Revised Returns till 31st March 2027(if duly passed and enforced by the IT Department) by paying a nominal fee for the period 1st January to 31 March 2027.
