We're a marketing agency, not tax experts. So before this year's ITR deadline, we did the sensible thing — got a CA on a call and asked every question our team had.
These are the notes. We compiled them for our own team first; sharing because half of India is about to file in a panic and some of this genuinely saves money.
First, the dates (miss these and everything else is moot)
| Who you are | Your deadline |
|---|---|
| Salaried / ITR-1, ITR-2 | 31 July 2026 |
| Business/professional, no audit (ITR-3, ITR-4) | 31 August 2026 |
| Filed but made a mistake? Revised return allowed till | 31 March 2027 |
| Missed the deadline? Belated return (with penalty) till | 31 December 2026 |
Late filing costs ₹5,000 (₹1,000 if income under ₹5 lakh), plus interest on unpaid tax — and you lose the right to carry forward most losses. Filing on 30 July in a hurry is how mistakes happen; file this week instead.
The single biggest money decision: which regime?
This is where our CA said most people leave money on the table — they let the portal default decide instead of doing 10 minutes of math.
The old regime still wins for heavy deduction users. If you claim big HRA in a metro, ₹1.5L under 80C, health insurance for yourself and parents (80D), ₹50k extra NPS (80CCD(1B)), and home loan interest (up to ₹2L) — add it all up. If your total deductions are large, run both numbers before choosing.
The 10-minute check: use the income tax department's own calculator, enter your numbers both ways, pick the lower tax. Salaried people can switch regimes every year — there's no loyalty prize.
The checklist: 9 things to verify before you hit submit
- Download AIS and Form 26AS — the week you file, not last month's copy. These update as banks and employers report. Filing from a stale download is the #1 cause of mismatch notices.
- Reconcile everything against your own documents. Form 16, bank interest certificates, broker capital gains statements, rent receipts. If AIS shows income you forgot (an old FD, dividends), report it — the department already knows.
- Report ALL bank interest. Savings and FD interest is taxable even when TDS wasn't deducted. Old regime users: claim 80TTA (₹10k savings interest deduction; ₹50k under 80TTB for seniors).
- Get capital gains right — the rules changed. Equity LTCG is now 12.5% above a ₹1.25 lakh annual exemption; STCG on equity is 20%. Match every figure to your broker/AMC statement. And remember the ₹1.25L LTCG exemption resets yearly — if you're sitting on gains, harvesting up to the exemption each year is free money over time.
- Pick the correct ITR form. Capital gains, foreign assets, or more than one house property usually push you out of ITR-1. Wrong form = defective return notice.
- Claim every TDS credit. Check 26AS for TDS on FDs, dividends, even property transactions — if it was deducted, it's your money; claim it or lose it.
- Old regime filers: sweep your deductions. 80C (₹1.5L), 80D health premiums (₹25k + ₹50k for senior parents), 80CCD(1B) NPS (₹50k), 24(b) home loan interest, 80G donations (need receipts with the org's PAN). New regime filers: you still get the ₹75k standard deduction and employer NPS under 80CCD(2).
- Pre-validate your bank account on the portal — refunds only land in validated accounts.
- E-verify within 30 days of filing. An unverified return is treated as never filed. It takes 60 seconds with Aadhaar OTP. This is the most heartbreaking mistake on the list — people "file" and lose it all to a missed click.
If you already filed and spotted an error
Don't panic — the revised return window now runs till 31 March 2027. Fix it properly rather than hoping the mismatch goes unnoticed; the AIS means it won't be.
Questions we get a lot
Which tax regime should I choose for FY 2025-26?
Run your numbers under both regimes using the Income Tax Department’s calculator. The new regime can mean zero tax up to ₹12 lakh of taxable income, plus the ₹75,000 standard deduction for salaried people. The old regime may still win if your HRA, 80C, 80D, NPS and home-loan deductions are substantial.
What is the ITR filing deadline for AY 2026-27?
The deadline is 31 July 2026 for salaried taxpayers filing ITR-1 or ITR-2, and 31 August 2026 for business or professional taxpayers filing a non-audit ITR-3 or ITR-4 return.
How long do I have to e-verify my ITR?
You must e-verify within 30 days of filing. If the return is not verified within the permitted period, it can be treated as invalid. Aadhaar OTP is one of the available verification methods.
Can I revise my ITR after filing for AY 2026-27?
Yes. If you discover an error after filing, the revised-return window for AY 2026-27 runs until 31 March 2027, subject to the applicable rules and any additional fee that may apply after 31 December.
Figures checked against official Income Tax Department guidance for AY 2026-27, including the salaried taxpayer guide, ITR-1 FAQs and e-verification manual. Verified 14 July 2026.
