ITR Filing AY 2026-27: July 31 Deadline, ₹12 Lakh Zero-Tax Limit, New Regime Rules and Your Complete Filing Guide

Published: June 22, 2026

ITR filing for AY 2026-27 is the most consequential tax compliance task on the calendar for every earning Indian — and the July 31, 2026 deadline is now 39 days away. This assessment year also carries landmark changes: a new Income Tax Act replacing the 1961 Act, revised tax slabs that make income up to ₹12 lakh effectively zero-tax in the new regime, expanded eligibility for simplified ITR forms, and updated disclosure requirements that every taxpayer must understand before filing.

This is your definitive, end-to-end guide — covering every change that matters, the correct form for your income profile, the deadline structure, and the precise steps to file accurately without professional assistance if your income profile is straightforward.

The Landmark Change: New Income Tax Act 2025 — What It Means for AY 2026-27

Effective 1 April 2026, the Income Tax Act 1961 has been repealed. However, its provisions will continue to govern all tax years beginning before 1st April 2026. Taxpayers filing returns for AY 2026-27 (pertaining to the period governed by the old Act) in July 2026 will do so using the forms prescribed under the old Act. At the same time, advance tax payments for Tax Year 2026-27, commencing from June 2026, will be made in accordance with the new Act.

A new Income Tax Act, 2025, and Income Tax Rules, 2026 have come into force from April 1, 2026, replacing the old Income-tax Act, 1961. The concept of “Tax Year” replaces “previous year” used in the 1961 Act. The income of a Tax Year continues to be assessed after the end of that Tax Year, similar to the existing system.

The practical implication for AY 2026-27 filers: You use the existing ITR forms and the provisions of the Income Tax Act 1961. The new Act and its procedures apply to income earned from April 1, 2026 onwards — which you will file in 2027. For now, follow the existing rules as described in this guide.

ITR Filing Deadlines AY 2026-27 — The Non-Negotiable Dates

The due date to file ITR for FY 2025-26 (AY 2026-27) is 31st July 2026 for ITR-1 and ITR-2.

The revised return due date has been extended to March 31, 2027 from the earlier December 31, 2026. Note — if you revise after 9 months (after December 31), a fee of ₹1,000–₹5,000 applies.

Complete deadline structure:

Missing the July 31 deadline costs salaried filers a late filing fee of ₹1,000 (income up to ₹5 lakh) or ₹5,000 (income above ₹5 lakh), plus interest under Section 234A on any unpaid tax. More critically, capital losses cannot be carried forward if you file a belated return — a particularly significant penalty for investors.

The New Tax Regime’s ₹12 Lakh Zero-Tax Benefit — Understand This Correctly

Under the new tax regime, taxable income up to ₹12 lakh is completely tax-free due to the tax rebate of up to ₹60,000 under Section 87A. This is a major relief introduced in Budget 2025.

Under the new tax regime, income of ₹10 lakh is tax-free as taxable income up to ₹12 lakh is tax-free. For a salary income of ₹15 lakh, you pay ₹97,500 under the new tax regime and ₹2,57,400 under the old tax regime assuming no deductions for FY 2025-26.

The new tax regime slabs for AY 2026-27:

The Section 87A rebate of ₹60,000 ensures zero net tax liability for income up to ₹12 lakh. The effective zero-tax income is ₹12.75 lakh when the standard deduction of ₹75,000 for salaried employees is included, because the standard deduction reduces taxable income before the rebate calculation.

Critical nuance: The zero-tax benefit disappears completely the moment your income crosses ₹12 lakh. A person earning ₹12.1 lakh pays tax on their full income above ₹4 lakh — the rebate does not apply in tranches. This is a planning trigger for those near the threshold.

Choosing Between Old and New Tax Regime — The Decision Framework

For salaried employees, the new tax regime is better if there are no deductions or exemptions to claim. However, if the taxpayer has massive deductions and exemptions, the old tax regime might be better.

Non-business taxpayers including salaried and retired individuals can switch between old and new regime every year directly while filing the ITR. Business and professional taxpayers can switch only once and revert back only once.

The comparison calculation for a salaried professional earning ₹15 lakh annually:

Old Regime with maximum deductions:

• Standard Deduction: ₹50,000
• 80C (ELSS + EPF): ₹1,50,000
• 80D (Health Insurance): ₹25,000
• HRA Exemption (metro): ₹1,20,000
• Total Deductions: ₹3,45,000
• Taxable Income: ₹11,55,000
• Tax Payable: Approximately ₹1,17,000

New Regime:

• Standard Deduction: ₹75,000
• Taxable Income: ₹14,25,000
• Tax Payable: ₹97,500

For this example, the new regime saves approximately ₹19,500 despite fewer deductions — because the lower slab rates more than compensate for the lost deductions. As a general rule for FY 2025-26: if your total deductions (80C + 80D + HRA + home loan interest) exceed ₹3.75 lakh for a ₹15 lakh income, the old regime remains beneficial. Below that, the new regime is superior.

Use the official income tax calculator at the Income Tax Department portal to model both scenarios with your exact income and deductions before filing.

Key Changes to ITR Forms for AY 2026-27

A noteworthy relaxation has been provided in the eligibility conditions for filing ITR-1 and ITR-4. From AY 2026-27 onwards, taxpayers earning income from up to two house properties can also file ITR-1 and ITR-4, subject to satisfaction of other prescribed conditions. This amendment expands the scope of simplified return filing and benefits a large segment of salaried individuals and small taxpayers.

Additional changes in ITR forms for AY 2026-27:

Mandatory tenant disclosure: Where tax has been deducted under Section 194-IB, the taxpayer is required to furnish the tenant’s PAN or Aadhaar in the ITR form. Where tax has been deducted under Section 194-I, the tenant’s TAN must be reported. If you receive rental income with TDS deducted, this new disclosure is mandatory.

Foreign retirement accounts simplified: From AY 2026-27, retirement benefit accounts maintained in notified and non-notified foreign countries are no longer required to be reported in ITR-1 and ITR-4. This reduces compliance requirements for individuals holding such foreign retirement accounts.

Capital gains reporting simplified: From AY 2026-27, references to old tax rates have been removed and only the rates prescribed under the amended capital gains provisions continue to be reported, simplifying return filing for investors.

Which ITR Form Is Correct for You?

ITR-1 (Sahaj): Salaried individuals, pensioners, and those with income from one or two house properties and interest — total income below ₹50 lakh. Cannot be used if you have capital gains, foreign income, or more than two house properties.

ITR-2: Individuals and HUFs with income from salary plus capital gains, foreign income, or more than two house properties. No business income.

ITR-3: Individuals and HUFs with income from business or profession. Freelancers, consultants, and professionals earning above ₹50 lakh use this form.

ITR-4 (Sugam): Individuals, HUFs, and firms opting for presumptive taxation under Sections 44AD, 44ADA, or 44AE — income up to ₹50 lakh.

Choosing the wrong form results in a defective return notice from the Income Tax Department, requiring correction and refiling. Verify your income sources carefully against these criteria before selecting.

Step-by-Step Filing Process — AY 2026-27

Step 1: Collect all documents — Form 16 (from employer, usually available by June 15), Form 26AS and AIS (Annual Information Statement) from the Income Tax portal, bank interest certificates, investment proof for 80C/80D, and capital gains statements from your broker.

Step 2: Log in at the Income Tax e-filing portal. Check the pre-filled ITR — it automatically fetches salary, TDS, and investment data. Always verify this pre-filled data against your actual documents before submitting. Discrepancies between pre-filled data and actual income can result in scrutiny notices.

Step 3: Select the correct assessment year (AY 2026-27), the correct filing status (original, revised, or belated), and the correct ITR form.

Step 4: Choose your tax regime — old or new. Model both using the portal’s comparison tool and select the one that produces the lower tax liability.

Step 5: Enter all income details — salary, house property income, capital gains, other sources. Claim all eligible deductions. Verify tax payable against TDS already deducted.

Step 6: Pay any remaining tax liability before filing. Section 234B interest applies if advance tax was not paid. Unpaid self-assessment tax can be paid through the portal under “Pay Tax.”

Step 7: Submit and e-verify within 30 days using Aadhaar OTP, net banking, or demat account. An unverified return is treated as unfiled.

Step 8: Download the ITR-V acknowledgment and save it in your records.

The ITR filing deadline of July 31, 2026 is firm and enforced. File before the end of June if all documents are ready — early filers receive refunds faster, face fewer portal traffic issues, and have time to correct errors before the deadline.
