ITR Filing 2026: Which Form, What Documents, and What Happens If You Miss July 31
By Nitish Bharadwaj · Published Jul 17, 2026 · 6 min
Income tax return filing for FY 2025-26 (AY 2026-27) carries a July 31 deadline for most individual taxpayers. The biggest upfront decision is form selection — ITR-1 for simple salaried income, ITR-2 for capital gains and rental income, ITR-3 for business income, ITR-4 for presumptive taxation. Missing July 31 means a belated return under Section 139(4) with up to ₹5,000 penalty, loss of carry-forward for most losses, and refund delays. Get your Form 16, AIS/26AS, and capital gains statements ready before you begin.
Every year, two mistakes cost Indian taxpayers the most: picking the wrong ITR form (which means a defective return notice later) and waiting until the last week of July (which means a rushed filing with errors). This guide covers both — exactly which form to file based on your income type, every document to gather before you open the portal, and what the July 31 deadline actually means for refunds and losses.
Which ITR Form Do You Need for AY 2026-27?
| Form | Who Should File | Key Trigger | Cannot Use If |
|---|---|---|---|
| ITR-1 (Sahaj) | Salaried individuals, one house property, interest income | Total income up to ₹50 lakh | You have capital gains, foreign income, or more than one house property |
| ITR-2 | Individuals with capital gains, multiple properties, foreign income/assets | Capital gains from stocks, MFs, or property sale | You have income from business or profession |
| ITR-3 | Individuals with income from business or profession | Freelancers, consultants, traders (F&O) | Presumptive taxation scheme applies (use ITR-4) |
| ITR-4 (Sugam) | Presumptive income under Section 44AD/44ADA/44AE | Business income ≤₹2 crore declared at 8% / Professional income ≤₹50 lakh declared at 50% | You have capital gains or foreign assets |
The most common mistake: using ITR-1 when you have sold mutual funds or stocks during the year. Any equity, debt, or hybrid mutual fund redemption creates capital gains — which requires ITR-2 even if the amount is small. Check your AIS (Annual Information Statement) for all transactions the Income Tax Department has already recorded. Our ITR-1 vs ITR-2 detailed guide covers every edge case.
Documents to Gather Before You Open the Portal
- Form 16 (Part A and Part B) from your employer — covers salary, allowances, and TDS already deducted
- AIS / Form 26AS from the Income Tax portal — cross-check all TDS credits, high-value transactions, and interest income
- Capital gains statements from your broker (Zerodha, Groww, etc.) — most brokers now auto-generate ITR-ready statements
- Mutual fund capital gains statement — download from CAMS/KFintech or individual AMC portals
- Bank interest certificates for savings accounts and fixed deposits (Section 80TTA / 80TTB deduction)
- Home loan interest certificate (Section 24 deduction under old regime)
- Rent receipts and landlord PAN if HRA exemption applies
- Health insurance premium receipts for Section 80D deduction
- Donation receipts with 80G registration details if applicable
The July 31 Deadline — and What Happens After
July 31, 2026 is the due date for individual taxpayers (except those who require audit). Filing after this date is still allowed under Section 139(4) as a belated return — but with consequences:
If you've already missed July 31, our full breakdown of belated return rules covers the Section 234A interest calculation month by month, exactly which losses you forfeit, and what an Updated Return (ITR-U) costs if you miss December 31 too.
New vs Old Regime — Decide Before You File
If you are on the old regime, you need deduction proofs (80C, 80D, HRA, home loan interest) ready before filing. If you are switching to the new regime, there is no going back for business income — salaried individuals can switch each year. Our new vs old tax regime 2026 guide has the complete breakeven analysis by income level, and our new regime for salaried employees covers the HRA and home loan exceptions.
After filing, if your refund does not appear within 30–45 days, check for mismatches between your ITR and Form 26AS. Our guide on why ITR refunds get delayed covers the five most common causes and how to fix each one.
Frequently Asked Questions
Can I file ITR-1 if I sold mutual funds this year?
No. Any mutual fund redemption creates capital gains, which makes you ineligible for ITR-1 regardless of the amount. You must use ITR-2. Filing ITR-1 with capital gains income will result in a defective return notice from the Income Tax Department.
What is the last date to file ITR for FY 2025-26?
July 31, 2026 for most individual taxpayers. For those whose accounts are subject to audit, the deadline is October 31, 2026. A belated return can be filed until December 31, 2026, with a penalty of ₹5,000 (₹1,000 if total income is below ₹5 lakh).
Is AIS the same as Form 26AS?
No — they serve different purposes. Form 26AS shows TDS credits (how much tax has already been deducted and deposited against your PAN). AIS (Annual Information Statement) is broader: it captures all transactions the Income Tax Department has data on, including mutual fund purchases, property sales, large cash deposits, and dividend income. Always reconcile both before filing.
