Complete Guide to ITR Filing for AY 2026-27: Everything You Need to Know
Filing your Income Tax Return (ITR) is one of the most important financial responsibilities for every taxpayer in India. With Assessment Year (AY) 2026-27 (covering income earned in Financial Year 2025-26) underway, taxpayers need to understand the latest due dates, ITR forms, tax slabs, and filing process. This pillar guide covers everything — from choosing the right ITR form to avoiding penalties — so you can file your return accurately and on time.
What is AY 2026-27?
AY 2026-27 refers to the Assessment Year in which income earned during Financial Year (FY) 2025-26 (April 1, 2025 to March 31, 2026) is assessed and taxed. Even though the new Income Tax Act, 2025 comes into force from April 1, 2026, AY 2026-27 covers income earned before that date, so your return for this year is still governed entirely by the old Income Tax Act, 1961. This makes AY 2026-27 the last filing season under the familiar 1961 framework.
ITR Filing Due Dates for AY 2026-27
Unlike a single common deadline for everyone, the due date depends on the type of taxpayer, the ITR form applicable, and whether a tax audit is required.
| Taxpayer Category | ITR Form | Due Date |
|---|---|---|
| Salaried individuals, pensioners, investors (no audit) | ITR-1, ITR-2 | 31 July 2026 |
| Business/professional income, no tax audit required | ITR-3, ITR-4 | 31 August 2026 |
| Taxpayers subject to tax audit | ITR-3, ITR-5, ITR-6 | 31 October 2026 |
| Tax audit report submission | — | 30 September 2026 |
| Transfer pricing cases (audit report) | — | 31 October 2026 |
| Transfer pricing cases (ITR filing) | — | 30 November 2026 |
| Belated return | Any applicable form | 31 December 2026 |
| Revised/updated return | Any applicable form | 31 March 2027 |
Key point: If you have simple income — salary, house property (up to two houses), long-term capital gains under Section 112A up to ₹1.25 lakh, and other income like interest — with total income not exceeding ₹50 lakh, you likely qualify for ITR-1 and must file by 31 July 2026. Business owners and professionals without audit obligations now get an extra month, until 31 August 2026.
Note: The government can extend deadlines through CBDT notifications, but extensions are never guaranteed. It's best to file well before the due date rather than waiting for a possible extension.
Which ITR Form Should You File?
Choosing the correct ITR form is critical — filing the wrong form can lead to your return being treated as defective.
ITR-1 (Sahaj)
For resident individuals with:
- Salary or pension income
- Income from one house property
- Other income such as interest
- Long-term capital gains under Section 112A up to ₹1.25 lakh
- Total income up to ₹50 lakh
ITR-2
For individuals and HUFs who:
- Have income from capital gains, multiple house properties, or foreign assets
- Do not have business or professional income
- Exceed the ITR-1 income or asset thresholds
ITR-3
For individuals and HUFs with income from business or profession (including freelance income), especially those maintaining regular books of accounts.
ITR-4 (Sugam)
For resident individuals, HUFs, and firms (other than LLPs) who:
- Have opted for the presumptive taxation scheme
- Have income from up to two house properties
- Meet conditions similar to ITR-1 otherwise
ITR-5, ITR-6, ITR-7
For firms, LLPs, companies, and trusts respectively — typically filed with professional assistance due to complexity.
Income Tax Slabs for FY 2025-26 (AY 2026-27)
Budget 2026 made no changes to slab rates, standard deduction, or rebate limits from the previous year, so the following rates continue to apply.
New Tax Regime (Default Regime)
| Income Slab | Tax Rate |
|---|---|
| Up to ₹4,00,000 | Nil |
| ₹4,00,001 – ₹8,00,000 | 5% |
| ₹8,00,001 – ₹12,00,000 | 10% |
| ₹12,00,001 – ₹16,00,000 | 15% |
| ₹16,00,001 – ₹20,00,000 | 20% |
| ₹20,00,001 – ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
- A standard deduction of ₹75,000 applies to salaried taxpayers and pensioners.
- Under Section 87A, resident individuals with taxable income up to ₹12,00,000 get a rebate of up to ₹60,000, making tax liability effectively zero.
- With the standard deduction, salaried individuals earning up to ₹12.75 lakh pay no tax at all.
- Marginal relief applies for incomes just above ₹12 lakh, so the extra tax is capped at the amount by which income exceeds ₹12 lakh.
- These slabs apply uniformly to all age groups — there's no extra age-based exemption in the new regime.
- The new regime is the default regime; you must actively opt for the old regime if you want to use it.
Old Tax Regime
| Income Slab (below 60 yrs) | Tax Rate |
|---|---|
| Up to ₹2,50,000 | Nil |
| ₹2,50,001 – ₹5,00,000 | 5% |
| ₹5,00,001 – ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
- Senior citizens (60–80 years) get a higher exemption limit of ₹3,00,000; super senior citizens (80+) get ₹5,00,000.
- Standard deduction of ₹50,000 is available.
- Allows deductions under Section 80C (up to ₹1.5 lakh), 80D, HRA, home loan interest, and more.
- Income up to ₹5 lakh can be effectively tax-free due to the rebate under Section 87A.
Old vs New Regime: The right choice depends on how many deductions and exemptions you can claim. If you have significant investments (80C), home loan interest, HRA, or medical insurance, the old regime may still work out cheaper. If you have few deductions, the new regime's lower rates and higher rebate typically win.
Documents Required for ITR Filing
Before you begin, gather these documents:
- Form 16 (from employer, for salaried individuals)
- Form 26AS and Annual Information Statement (AIS) — to verify TDS/TCS and reported income
- Bank account statements and interest certificates
- Capital gains statements (from brokers/mutual fund houses, if applicable)
- Home loan interest certificate (if claiming deductions)
- Investment proofs for deductions (80C, 80D, etc.) if opting for the old regime
- PAN and Aadhaar (linked)
- Rent receipts (if claiming HRA)
- Business/professional income records (for ITR-3/ITR-4 filers)
Step-by-Step ITR Filing Process
-
Log in to the Income Tax e-filing portal using your PAN/Aadhaar.
- Select the Assessment Year — AY 2026-27 — and the applicable ITR form.
- Choose your tax regime — new (default) or old, as per your eligibility and benefit analysis.
- Pre-fill and verify data — most personal details, salary, TDS, and interest income are pre-filled from Form 26AS and AIS. Cross-check for accuracy.
- Report all income sources — salary, house property, capital gains, business/professional income, and other income.
- Claim eligible deductions and exemptions (if under the old regime).
- Compute tax liability — the portal auto-calculates tax payable or refund due after adjusting TDS/TCS and advance tax paid.
- Pay any balance tax due before submitting the return, if applicable.
- Submit the return and complete e-verification (via Aadhaar OTP, net banking, or other methods) within 30 days of filing — an unverified return is treated as not filed.
- Download the acknowledgment (ITR-V) for your records.
What Happens If You Miss the Deadline?
-
Belated Return: You can still file until 31 December 2026 under Section 139(4), but this attracts a late fee under Section 234F (up to ₹5,000, or ₹1,000 if total income is below ₹5 lakh) and interest at 1% per month on unpaid tax.
- Loss of Benefits: Filing late means you cannot carry forward certain business or capital losses, and if you miss the original due date, you also lose the option to switch to the old tax regime for that year (for salaried taxpayers under ITR-1/ITR-2).
- Revised Return: If you spot an error after filing — even a belated one — you can file a revised return under Section 139(5), generally up to 31 March 2027.
- Updated Return: The updated return facility allows you to voluntarily disclose omitted income or correct past mistakes, with losses declared in updated returns now allowed to be carried forward, subject to conditions.
Why You Should File ITR Even If Your Income Is Below the Exemption Limit
Filing ITR isn't just about paying tax — it's also useful for:

- Building a clean financial and compliance track record
Benefits of Filing Early
- Faster processing of tax refunds
