How Do You Actually File Your ITR Online in India (And Why Everyone Gets the Deadline Wrong)?

Ask five people when the ITR deadline is this year and you will get five different answers. Some say July 31, because that number has been drilled into everyone since school. Some say September 15, because that is what happened last year when the income tax department pushed the date out at the last minute. A few will swear it is now August 31, because that is what showed up in a WhatsApp forward about some “new tax act.”

They are all a little bit right, which is exactly the problem.

At HMA Wealth, we hear a version of this question every single year around this time: which date do I actually trust, and how do I file my ITR online without something going wrong in the process? Sorting out exactly this kind of shifting-target confusion, using the current rules instead of whatever screenshot is doing the rounds this week, is a big part of why HMA Wealth exists. So let’s slow down and go through how to file ITR online in India properly, step by step, the way you would want a knowledgeable friend to explain it rather than a government circular.

Here is the honest, current answer. For FY 2025-26 (AY 2026-27), the standard cut-off for salaried individuals filing ITR-1 or ITR-2 is 31 July 2026. If you run a business or a profession and do not need a tax audit, filing ITR-3 or ITR-4, you get an extra month, till 31 August 2026. Treat both of these as the current default, not as gospel. The date has moved before, it slid to 15 September in 2025, and with the new Income Tax Act, 2025 now running the show in place of the old 1961 Act, another shift is entirely possible before the season ends. Check the notice board on the Income Tax Department’s e-filing portal before you plan your last week around any single number.

What Actually Changed in How You File Your ITR This Year?

This is the first assessment year you will file your ITR online under the Income Tax Act, 2025, which replaced the 1961 Act that every working Indian grew up hearing about. Most tax professionals agree the rewrite is mainly about reorganising and simplifying language rather than changing how much tax you owe, but section numbers and cross-references have shifted, so old blog posts (including some you’ll find while Googling this) may quote provisions that no longer exist under the same numbering.

What has not changed is the basic shape of the choice you make every year when you file your ITR online: old tax regime or new tax regime. The new regime continues as the default, which means if you do nothing, the system files you under it automatically. Here are the slabs for FY 2025-26 under the new regime, as they stood after Budget 2025:

A rebate under Section 87A, currently up to ₹60,000, means individuals with taxable income up to around ₹12 lakh effectively pay nil tax under the new regime, and salaried taxpayers get there closer to ₹12.75 lakh once the standard deduction is applied. That is an illustrative figure based on how the rebate is structured today, not a promise about your own tax bill, and it is exactly the kind of number that shifts with each Budget, so verify it against the Income Tax Department’s site before you rely on it.

Which ITR Form Do You Actually Need?

Picking the wrong form is one of the quietest ways people mess up filing their ITR online, because the portal often auto-suggests one based on incomplete information, and it is easy to just click through. Get this step wrong and the rest of your online ITR filing gets messy fast, so it is worth thirty seconds of thought before you move on.

Here is a scenario that trips up a lot of first-time filers who have gotten into investing over the past couple of years. Say you have a salary, a couple of SIPs, and you also sold a few Nifty ETF units on Zerodha during the year to fund a phone upgrade. The moment that sale crosses the small long-term capital gains threshold under Section 112A, ITR-1 is no longer the right form, and you need ITR-2 instead to file your ITR online correctly. Zerodha’s Console (or Groww’s equivalent tax report) will give you a capital gains statement for the year, and that document becomes essential once you are filling this in. If you are still fuzzy on how a demat account and capital gains actually connect, HMA Wealth’s explainer on demat accounts is a useful primer before you go further.

What Documents Do You Actually Need Before You Start?

Filing your ITR online goes faster and with fewer errors when you have these open in another tab before you log in, rather than hunting for them halfway through. This is roughly the checklist HMA Wealth points readers to every filing season, in the order it usually gets needed:

• PAN and Aadhaar, linked to each other and to your bank account
• Form 16 from your employer, which is your TDS certificate on salary
• Form 26AS, the tax credit statement showing every TDS and TCS credited against your PAN
• Annual Information Statement (AIS) and Taxpayer Information Summary (TIS), available on the portal, which now track interest, dividends, and mutual fund or stock transactions in far more detail than they used to
• Bank interest certificates for savings accounts and fixed deposits
• Capital gains statement from your broker if you sold stocks, ETFs, or mutual fund units
• Rent receipts or a home loan interest certificate, if you are claiming HRA or a Section 24 deduction
• Investment proofs, such as ELSS statements, PPF passbook, or insurance premium receipts, only if you are opting for the old regime and claiming Section 80C or 80D
• A pre-validated bank account on the portal, so any refund actually reaches you

How Do You Actually File Your ITR Online Step by Step?

This is the part people dread, but once you have the documents above in hand, filing your ITR online genuinely takes most salaried filers under half an hour.

1. Log in to the e-filing portal. Go to incometax.gov.in and sign in using your PAN as the user ID.
2. Start a new return. Navigate to e-File, then Income Tax Returns, then File Income Tax Return, and select the correct assessment year (AY 2026-27 for income earned in FY 2025-26).
3. Let the portal pre-fill your data, but don’t trust it blindly. It pulls from your Form 16, Form 26AS, and AIS automatically. Cross-check every figure against your own documents before moving forward, since mismatches here are the single most common reason returns get flagged for a follow-up.
4. Confirm the ITR form. The system suggests one based on what it sees in your AIS, but you know your income better than it does, so verify it matches the table above.
5. Choose your tax regime. The new regime is pre-selected. If you want the old regime and you have business or professional income, you will also need to submit Form 10-IEA separately, so check whether that applies to you before you proceed.
6. Fill in and verify each income head, salary, house property, capital gains, and other income, and claim deductions if you are on the old regime.
7. Let the portal compute your tax payable or refund. If tax is due, pay it through the built-in Challan 280 process before you submit, not after.
8. Preview the entire return carefully, then submit it, and e-verify immediately. Aadhaar OTP is the fastest route and takes under two minutes for most people.

Which Tax Regime Should You Actually Pick, Old or New?

This is genuinely one of those questions with no single right answer, and anyone who tells you otherwise is guessing on your behalf without knowing your numbers. It is also the single decision that most changes what filing ITR online actually costs you, so it deserves more than a coin flip.

As a purely illustrative example, take someone with a ₹12 lakh salary who claims ₹1.5 lakh under Section 80C, ₹50,000 under Section 80D, and roughly ₹2 lakh in home loan interest under Section 24. Under the old regime, those deductions bring their taxable income down meaningfully before any slab rate applies. Under the new regime, none of those specific deductions are available, but the slabs themselves are lower and the standard deduction is higher. Whether the old regime still wins for this person depends entirely on how much they are actually claiming, and it is not automatic. This is illustrative only, not a recommendation, and your own number could land differently.

If you genuinely use your Section 80C limit every year (through ELSS funds, PPF, or life insurance) and pay meaningful home loan interest or HRA, the old regime is worth running the numbers on before you assume the new one is better just because it is the default. HMA Wealth’s piece on tax-saving investments walks through what actually counts toward that ₹1.5 lakh limit, and HMA Wealth’s NPS tax benefits guide covers the additional ₹50,000 deduction under Section 80CCD(1B), which is one of the few deductions still available even for some new-regime filers depending on the type of contribution.

What Mistakes Do People Actually Make When Filing ITR Online?

These are the patterns that show up again and again in the questions HMA Wealth gets from readers filing ITR online for the first or second time:

• Trusting AIS and Form 26AS without checking them against your own certificates. These systems have gotten far more detailed, but they are not infallible, and a mismatch can delay your refund or trigger a notice you did not need.
• Leaving out savings account and FD interest because no TDS was deducted on it. Interest income under ₹10,000 from a savings account has no TDS, but it is still taxable and still needs to be reported.
• Skipping small capital gains because “it was only ₹8,000 profit” and quietly hoping it won’t matter when you file your ITR online. The AIS now picks up most of these transactions anyway, so leaving them out just creates a mismatch instead of avoiding tax.
• Filing your ITR online under ITR-1 when the income no longer fits it, especially once someone starts investing in ETFs or international stocks through platforms like INDmoney and crosses the capital gains threshold.
• Skipping the e-verification step. This is the most common one, and it is the most costly, because an unverified return is treated as never filed at all.
• Getting the refund bank account wrong or forgetting to pre-validate it after you file your ITR online, which leaves a genuine refund stuck for months.

What Happens If You Miss the Deadline or Get Something Wrong?

Life happens, and the system does account for that, though not for free. Even if you already filed your ITR online and only realise the problem afterward, you usually still have a path to fix it.

These windows have shifted under the Income Tax Act, 2025, so treat the exact dates here as a starting point and confirm the current figures on the Income Tax Department’s portal if you are actually in one of these situations, rather than relying on last year’s numbers.

How Do You Actually Verify Your ITR After Filing?

Submitting the return is only half the job of filing your ITR online. Until you verify it, it does not legally exist as a filed return.

You have a few ways to do this: Aadhaar OTP, net banking, a bank account EVC, a demat account EVC, or sending a physical signed ITR-V by post, though almost nobody uses that last option anymore. Aadhaar OTP is the quickest for most salaried filers.

The window to do this is 30 days from the date you submit, not 30 days from the due date. Miss it, and the return is treated as though it was never filed, which means starting over as a belated return, with the late fee that comes with it.

A quick honest note before you go. Everything above is meant to help you understand how to file ITR online in India, not to replace professional advice for your own specific return. HMA Wealth is not a SEBI-registered investment adviser, and nothing here should be read as personalised tax guidance. If your income involves foreign assets, business income, or anything beyond a fairly straightforward salary, it is worth what a good CA charges, often somewhere in the ₹500 to ₹1,500 range for a simple return, to get a second pair of eyes on it before you hit submit.

The first time you file your ITR online, it feels a little like defusing something. By your second or third year, once you know which documents to pull and which form actually applies to you, it becomes a twenty-minute task you do with a cup of chai next to you. That, more than any specific rule in this piece, is the whole point of getting the process right once.

If you are still building your investing habits alongside all this, HMA Wealth’s guide on how to start investing in India is a reasonable next stop once this year’s ITR filing is done and out of the way.
