ITR Filing 2026: The July 31 Deadline and Which Regime to Pick

If you earn in India and you've been putting off the one financial chore that comes around every summer, this is your reminder. Filing your income tax return (ITR) for the year gone by is back on the calendar, and the headline date for most people is 31 July 2026. That's the last day to file for the financial year 2025-26, known in tax language as assessment year AY 2026-27, if your accounts don't need an audit.

The bigger question this year isn't really when to file. It's which tax regime to file under. The government has spent the last two budgets quietly tilting the field toward the new regime, and for a large share of salaried Indians the choice is now close to settled. Here's what's true right now, the numbers that actually matter, and the steps to get it done without a last-minute scramble.

The dates you can't miss

The income tax portal opens the relevant forms in stages through the early summer, and the clock is the same for almost everyone with a salary, pension, rent or capital gains and no audit requirement.

• 31 July 2026 — last date to file for salaried individuals, pensioners and others not requiring an audit (ITR-1, ITR-2, and non-audit ITR-3/ITR-4).
• 31 October 2026 — due date for taxpayers whose accounts must be audited, such as many businesses.
• 30 November 2026 — for those filing a transfer pricing report.
• 31 December 2026 — the final cut-off for a belated or revised return for the year.

One caveat worth stating plainly: the 31 July date has been pushed back in some recent years when the portal or forms ran late. Last year, for instance, the non-audit deadline slipped past July. Treat 31 July as the real target and don't bank on an extension that may never come.

What it costs to file late

Missing the deadline isn't fatal, but it isn't free either. File after 31 July and Section 234F kicks in with a flat late fee.

• Rs 5,000 if your total income is above Rs 5 lakh.
• Rs 1,000 if your total income is up to Rs 5 lakh.
• Nothing if your income is below the basic exemption limit and you weren't required to file.

On top of that, if you still owe tax, Section 234A adds interest at 1% per month (or part of a month) on the unpaid amount from the day after the deadline until you actually pay. There's a quieter cost too: file a belated return and you lose the right to carry forward business and capital losses to set off against future gains. For anyone with stock-market or business losses to bank, that alone is reason enough to file on time.

The new regime is now the default

Here's the single most important shift to absorb. Unless you actively say otherwise, you are now taxed under the new tax regime. It has become the default setting, and the old regime is the option you have to consciously reach for.

The new regime's slabs for FY 2025-26 stack up like this:

• Up to Rs 4 lakh: nil
• Rs 4-8 lakh: 5%
• Rs 8-12 lakh: 10%
• Rs 12-16 lakh: 15%
• Rs 16-20 lakh: 20%
• Rs 20-24 lakh: 25%
• Above Rs 24 lakh: 30%

The number that does the heavy lifting is the Section 87A rebate, now worth up to Rs 60,000 under the new regime. In plain terms, if your taxable income is Rs 12 lakh or less, your tax works out to zero. Add the Rs 75,000 standard deduction that salaried people and pensioners get automatically, and a salaried earner pays no tax up to roughly Rs 12.75 lakh of gross salary. That is a genuinely large band of the workforce now sitting at a zero bill without having to invest a single rupee to save tax.

The trade-off is that the new regime strips away almost all the familiar deductions. No 80C for your provident fund or insurance, no HRA exemption, no 80D for health premiums, no home-loan-interest break for a self-occupied house. You get the standard deduction and the lower slabs, and little else.

When the old regime still wins

The old regime keeps the smaller basic exemption — Rs 2.5 lakh for those under 60, Rs 3 lakh for senior citizens and Rs 5 lakh for the very elderly — and a much lower 87A rebate that makes income tax-free only up to Rs 5 lakh. Its higher slab rates bite sooner. What it offers in return is the full menu of deductions.

That menu only pays off if you actually use it. Roughly speaking, the old regime starts beating the new one once your total deductions cross about Rs 3.5-4 lakh for the year. To get there you typically need a serious stack: the full Rs 1.5 lakh under 80C, a chunky HRA claim if you rent, Rs 2 lakh of home-loan interest, health insurance under 80D, maybe an NPS top-up under 80CCD(1B).

So the rough decision tree looks like this:

1. Renting in a costly city with a home loan and a full 80C? Run the numbers — the old regime may still save you tens of thousands.
2. Young, salaried, few investments, no big loans? The new regime almost certainly wins, and you skip the paperwork of proving deductions.
3. Income comfortably under Rs 12.75 lakh and salaried? The new regime likely zeroes your bill outright. There's little to decide.

Use the official tax calculator on the income tax website, plug in both regimes, and let the smaller number choose for you. The instinct to chase deductions made sense for a generation of taxpayers; for many today, the math has simply moved on.

How to actually file

The process online is more forgiving than its reputation. A clean run looks like this:

1. Gather your papers — Form 16 from your employer, interest certificates from banks, capital-gains statements from your broker or mutual fund, and proof of any deductions if you're going old-regime.
2. Check your AIS and Form 26AS on the portal. These show the income and tax already reported against your PAN. Reconcile them with your own records before you file — mismatches are the top trigger for notices.
3. Log in at incometax.gov.in, pick the right form (ITR-1 for simple salaried income up to Rs 50 lakh, ITR-2 if you have capital gains or more than one house), and choose your regime.
4. Review the pre-filled data, add anything missing, and pay any balance tax due.
5. Submit and then e-verify — usually via Aadhaar OTP — within 30 days. An unverified return is treated as not filed, so don't stop at "submitted."

Salaried taxpayers can switch regimes year to year simply by choosing at the time of filing. If you have business or professional income and want the old regime, you must file Form 10-IEA to opt out of the default, and your ability to flip back and forth is limited. That asymmetry is deliberate — the system wants the new regime to be the path of least resistance.

Don't wait for July

The smartest move is to file early, ideally in the weeks after you've received Form 16 and your AIS has settled. Early filers get faster refunds, avoid the late-July portal crush, and leave themselves room to spot and fix errors before the deadline rather than after. Filing isn't only about avoiding a penalty either — a filed return is the document banks, visa officers and loan desks ask to see, and it's how you claim back excess TDS that's been sitting with the government interest-free.

For most people this year, the honest summary is short. The new regime is the default, it's tax-free up to about Rs 12.75 lakh for the salaried, and unless you have a fat folder of deductions, the decision is largely made for you. Confirm with the calculator, file before 31 July, e-verify, and you're done for another year.
