How to File ITR Online: Step-by-Step Guide (AY 2026-27)

Business / Jun 13, 2026

How to File ITR Online

Filing your ITR online for AY 2026-27 basically comes down to this: log in to the income tax e-filing portal with your PAN, head to e-File → Income Tax Returns → File Income Tax Return, and select AY 2026-27. Pick "Online" as your mode, choose the right ITR form (most people will use ITR-1 to ITR-4), and let the portal pre-fill your salary, TDS, and bank details from Form 26AS and AIS. Go through each section, check that the numbers actually match your Form 16 and bank statements, add any deductions you're claiming, and submit.

One thing people often miss — submitting isn't the end. You still have to e-verify within 30 days, either through Aadhaar OTP (the easiest option for most people) or by sending a signed ITR-V to CPC Bengaluru.

If you're salaried with straightforward income, ITR-1 is usually what applies, and this year's deadline for ITR-1 and ITR-2 (without audit) is 31st July 2026.

Feeling unsure about which form applies to you, or whether you're missing something? That's exactly the kind of thing our team at Legal-N-Tax Advisory deals with every day — happy to take a look if you'd rather not navigate it alone.

Why Bother Filing If Your Tax Is Already Deducted?

This comes up a lot. People assume that once their employer deducts TDS every month, the job is basically done. It isn't, really.

Your ITR is a separate declaration — it's where you tell the government, in one consolidated document, what you earned across all sources, what deductions you're claiming, and how much tax has already been paid on your behalf. It's also the only way to actually get back excess TDS if too much was deducted.

And there are practical reasons to keep your filings clean even if you think you don't "need" to:

  • Visa applications for the US, UK, Canada, and most of Europe often ask for ITR copies going back two or three years
  • Banks want to see ITRs before approving home loans, car loans, or even some credit cards
  • If you've made a capital loss this year, you can only carry it forward to offset future gains if you've filed on time
  • Landlords, in some cities, ask for ITR as proof of income for rental agreements

So even if your tax situation feels "simple," filing on time keeps a lot of doors open later.

What's Changed for AY 2026-27 (FY 2025-26)

A few updates worth knowing about before you start:

ITR-1 and ITR-4 now cover more people. If you have long-term capital gains up to ₹1.25 lakh under Section 112A — say, from selling some equity shares or mutual fund units — you can still use the simpler ITR-1 or ITR-4, as long as you don't have any losses to carry forward.

Presumptive taxation limits went up. Section 44AD's turnover limit is now ₹3 crore, and for professionals under 44ADA, it's ₹75 lakh. That means more small business owners and freelancers qualify for the simpler ITR-4 route this year.

You get more time to fix mistakes. The window to file a revised return now extends to 31st March of the assessment year (it used to close on 31st December), though there's a small fee if you revise after the original due date.

Updated returns (ITR-U) are more flexible. Even if the department has already started reassessment proceedings, you can still file an updated return — by paying an extra 10% tax — within 48 months of the relevant assessment year ending.

Before You Start: What to Keep Handy

Honestly, half the frustration with ITR filing comes from hunting for documents midway through. Save yourself the trouble and gather these first:

  • PAN and Aadhaar (make sure they're linked, and Aadhaar OTP is active for verification)
  • Form 16 — from every employer you worked with this year, if you switched jobs
  • Form 26AS and AIS, downloaded fresh from the portal
  • Bank statements for the financial year
  • Proof of investments — PPF, ELSS, LIC premiums, health insurance, anything you're claiming under deductions
  • Capital gains statements from your broker, if you sold shares or mutual fund units
  • Rent receipts or your home loan interest certificate, if you're claiming HRA or home loan deductions
  • Any other income — savings account interest, FD interest, dividends — even the small amounts

The Actual Step-by-Step Process

1. Log in to the e-filing portal

Head to incometax.gov.in and log in with your PAN as the user ID. First time here? You'll need to register using your PAN, basic details, and a mobile number/email linked to your Aadhaar.

2. Pull your Form 26AS and AIS — and actually check them

This step gets skipped more often than it should. Before touching the ITR form itself, download both Form 26AS and AIS from the portal and compare them line by line against your Form 16, bank interest certificates, and any capital gains statements.

If something in AIS looks off — an amount that doesn't match, or income you don't recognize — raise it as feedback right there in the AIS section. It creates a record, and it genuinely helps avoid mismatch notices down the line.

3. Go to 'File Income Tax Return.'

From the e-File menu, select Income Tax Returns, then File Income Tax Return.

4. Pick the assessment year and mode

Choose AY 2026-27 (this covers income from FY 2025-26), select Online as your filing mode, and indicate whether this is your original return or a revision.

5. Confirm your filing status

Individual, HUF, or "Others" — most people reading this will select Individual.

6. Choose the right ITR form

This is where a lot of returns go wrong, and it's worth slowing down here. Filing under the wrong form can get your return flagged as defective under Section 139(9), which means more back-and-forth later.

Form Best Suited For
ITR-1 (Sahaj) Resident individuals earning up to ₹50 lakh from salary, one house property, and other sources like interest. It now also covers LTCG up to ₹1.25 lakh under Section 112A, provided there are no brought-forward or carry-forward capital losses.
ITR-2 Individuals or HUFs with capital gains exceeding the above limit, more than one house property, foreign income or assets, or total income above ₹50 lakh, but without business or professional income.
ITR-3 Individuals or HUFs having income from business or profession and not opting for the presumptive taxation scheme.
ITR-4 (Sugam) Resident individuals, HUFs, or firms (excluding LLPs) opting for presumptive taxation under Sections 44AD, 44ADA, or 44AE, with total income up to ₹50 lakh.

If your income is a mix — say, salary plus some freelance work, or salary plus stock market gains — it's genuinely worth double-checking which form fits before you commit. Correcting it later isn't impossible, but it's a hassle you can avoid.

7. Tell the portal why you're filing

You'll be asked the reason — total income above the basic exemption limit, claiming a refund, carrying forward a loss, and so on. Pick whichever applies.

8. Go through the pre-filled data carefully

The portal pulls in a lot automatically from your PAN, Form 16, AIS, and 26AS — personal details, salary figures, TDS, bank account info. Don't just click through. Check each section:

  • Personal information, including the bank account where you want any refund credited
  • Gross total income — salary, house property, capital gains, other income
  • Deductions under Chapter VI-A — 80C, 80D, 80G, 80TTA, and so on
  • Tax already paid — TDS, TCS, advance tax, self-assessment tax

It's common to find small errors here — a digit off in the bank account number, or a salary figure that doesn't quite match Form 16. Catching these now saves a lot of trouble later.

9. Pick your tax regime

The portal will show you a comparison between the old regime (with deductions) and the new regime (lower rates, fewer deductions). It's worth actually working through both yourself, especially if you have significant 80C investments, HRA, or home loan interest — for a lot of people, the old regime still comes out ahead despite all the talk about the new one.

10. Review the computed tax

Once everything's filled in, the system calculates your final tax position — payable or refundable. This is your last real chance to catch anything before it's locked in, so give it a proper read.

11. Submit

Hit submit, and you'll get an acknowledgment (ITR-V). At this point, your return is filed — but not yet complete.

12. E-verify within 30 days

This part trips people up more than you'd expect. If you don't verify within 30 days, your return is treated as if it was never filed at all. The easiest route for most people is Aadhaar OTP — instant and done in seconds. Net banking and bank/demat EVC work too. The old-school option of printing, signing, and posting the ITR-V to CPC Bengaluru still exists, but most people won't need it.

Due Dates for FY 2025-26 (AY 2026-27)

Category Due Date
Individuals/HUF filing ITR-1 or ITR-2 (no audit) 31st July 2026
Individuals/businesses requiring audit (ITR-3, ITR-4) 31st August 2026
Businesses with international/specified domestic transactions 30th November 2026
Belated return 31st December 2026
Updated return (ITR-U) Within 48 months of the relevant AY ending

These dates can be extended by the CBDT, so it's worth checking the official portal closer to deadline season.

If You're a Salaried Employee, Here's the Short Version

  • Get Form 16 from every employer you worked for this year
  • Pull Form 26AS and AIS, and check them against your Form 16
  • ITR-1 is probably your form, unless you've got capital gains beyond the LTCG limit, foreign income, or more than one property — then it's ITR-2
  • Claim what you're entitled to — 80C, 80D, HRA, standard deduction
  • Run the numbers under both tax regimes before deciding
  • Submit, and don't forget the Aadhaar OTP verification step

Mistakes People Make More Often Than You'd Think

  • Picking the wrong ITR form for their actual income mix
  • Skipping the 26AS/AIS check and ending up with mismatches
  • Forgetting income from a previous employer after switching jobs mid-year
  • Submitting but never verifying — which technically means the return was never filed
  • Typos in bank account details that delay refunds for weeks
  • Not reporting small interest income just because no TDS was deducted on it
  • Sticking with whatever regime is "default" without actually comparing both

Frequently Asked Questions

What's the last date to file ITR for FY 2025-26 (AY 2026-27)? For most individuals filing ITR-1 or ITR-2 without an audit requirement, it's 31st July 2026. If you need ITR-3 or ITR-4 with audit, you get until 31st August 2026.

Can I file my ITR if I don't have Form 16? Yes. Your salary slips, bank statements, and the Form 26AS/AIS from the portal give you everything you need to work out your income and tax paid.

Which ITR form should a salaried person use? ITR-1 covers most salaried individuals earning up to ₹50 lakh with one house property and other minor income sources. If you've got capital gains beyond ₹1.25 lakh, foreign assets, or multiple properties, you'll need ITR-2 instead.

What happens if I forget to e-verify? Your return is treated as if it was never filed — which can mean penalties and the consequences of late filing, even though you technically submitted it on time.

Can I still file if I've missed the deadline? Yes, a belated return is possible until 31st December 2026 for this assessment year, though you may face a late fee and some interest.

How long does a refund usually take? Once you've e-verified successfully and your bank account is pre-validated, refunds typically come through within a few weeks — assuming there's nothing inconsistent in your return.

Should I just file it myself, or get help? If your income is purely salary with nothing complicated, the portal handles it fine on its own. But once you're dealing with capital gains, business income, foreign assets, multiple income sources, or you've gotten a notice in the past — it's usually worth talking to someone who does this regularly.
