This guide covers the deadlines, how to file your ITR, the old-versus-new regime choice, and the points that matter most for investors with more complex returns. The deadline link below goes to the official Income Tax e-filing portal, the only place to file and to confirm the latest dates.

ITR filing last date 2026: the deadlines that matter

The ITR filing last date is no longer one-size-fits-all; it now depends on which form applies to you:

Taxpayer / form Original due date Belated cutoff
Salary / capital gains, ITR-1, ITR-2 (non-audit)31 July 202631 Dec 2026
Business / professional, ITR-3, ITR-4 (non-audit)31 Aug 202631 Dec 2026
Audit cases31 Oct 202631 Dec 2026
Transfer pricing cases30 Nov 202631 Dec 2026

Miss the deadline and a late fee under Section 234F applies, up to Rs 5,000, or Rs 1,000 if total income is below Rs 5 lakh, along with interest on any tax due.

How to file your ITR: a step-by-step overview

For those less familiar with the process, here is how to file your ITR in plain steps. The return is filed online on the Income Tax Department's e-filing portal:

  1. Log in to the e-filing portal with your PAN (which doubles as your user ID) and password.
  2. Select assessment year 2026-27 and the ITR form that fits your income (more on forms below).
  3. Review the pre-filled data. Salary, interest, TDS and reported capital gains are increasingly auto-populated, but check them against your own records.
  4. Add anything missing, claim eligible deductions, and confirm your tax computation.
  5. Submit, then e-verify within the allowed window. A return is not complete until it is verified.

Most salaried filers find the online process manageable. It is the returns with capital gains and multiple income heads, common for investors, where care matters most.

New tax regime vs old: which applies to you

The new-versus-old tax regime choice trips up a lot of filers. For AY 2026-27, the new regime is the default; if you want the old regime (with its deductions like 80C, 80D, HRA and home-loan interest), you must actively choose it while filing.

If you file a belated return, you lose the option to use the old regime and are taxed under the new one by default, potentially losing valuable deductions. For anyone who benefits from the old regime, that alone is a strong reason to file on time.

Which regime saves you more depends entirely on your deductions and income mix; it is worth comparing both before you choose.

ITR and capital gains: what investors need to get right

This is where filing gets genuinely involved for investors. If you have sold shares, mutual funds, property, or other assets during the year, those gains across shares, property and other assets must be reported, and they generally require ITR-2 (or ITR-3 if you also have business income), not the simpler ITR-1.

A few points commonly cause errors: short-term and long-term gains are taxed differently and must be classified correctly; gains from different asset classes follow different rules; set-off of capital losses against gains has its own conditions; and foreign assets or income add further reporting requirements. For a portfolio of any complexity, this is where a return becomes genuinely involved, and where small mistakes can mean notices later.

Which ITR form should you file?

Choosing the wrong form is one of the most common filing errors. In brief: ITR-1 (Sahaj) suits simple salaried income, and newly this year, up to two house properties; ITR-2 covers salary plus capital gains and is the typical form for investors without business income; ITR-3 is for those with business or professional income; and ITR-4 (Sugam) is for presumptive-taxation cases. If you hold investments that generate capital gains, ITR-2 is usually your form, not ITR-1.

When DIY filing isn't enough: the SELEQT view

For a straightforward salaried return, self-filing on the portal is perfectly reasonable. The calculus changes as wealth and complexity grow. Multiple income sources, significant capital gains across asset classes, foreign holdings, business interests, family trusts, or recent large transactions all raise both the effort and the cost of getting it wrong. A missed disclosure or a misclassified gain can invite scrutiny long after the return is filed.

For families in that position, filing is less an administrative task than part of the year's overall tax and wealth planning. Done well, it is coordinated with how the portfolio is structured through the year, not left to a scramble in July. If your return has reached that level of complexity, it is worth having it handled by professionals who see your whole financial picture.

Frequently asked questions

What is the ITR filing last date for FY 2025-26?
For most individuals filing ITR-1 or ITR-2 (non-audit), the original due date is 31 July 2026. Business and professional non-audit cases (ITR-3, ITR-4) have until 31 August 2026, audit cases until 31 October, and transfer pricing cases until 30 November. Always confirm on the official portal, as dates can be extended.
Can I still file after the deadline?
Yes, a belated return can be filed up to 31 December 2026, but with a late fee under Section 234F and interest on any tax due. Importantly, a belated return cannot use the old tax regime.
Which ITR form do I need if I have capital gains?
Usually ITR-2, or ITR-3 if you also have business income. Capital gains cannot be reported in the simpler ITR-1.
Old regime or new regime, which is better?
It depends entirely on your deductions and income mix. Those with significant 80C, 80D, HRA or home-loan deductions often benefit from the old regime; others may pay less under the new one. Compare both before choosing, and remember the old regime is unavailable on a belated return.

Filing your return is the visible end of a year of financial decisions. For a simple return, the portal does the job; for a complex one, it pays to treat filing as part of a coordinated plan. If your return has grown complex, capital gains, multiple income heads, or assets that need careful structuring, we would be glad to begin that conversation with you.
