Picking the wrong ITR form is the most common filing mistake in India, and it is an expensive one: a return filed on the wrong form is treated as defective, the department issues a notice, and you have to file all over again — sometimes after the due date has passed. The rules are not intuitive either. A salaried person who sold ₹5,000 of a mutual fund can no longer use ITR-1. An F&O trader is filing business income, not capital gains. A person who simply holds shares in a friend’s private company is out of the short forms altogether. This tool walks through every disqualifier that matters, gives you a single confident answer, names the exact trigger, and tells you which form you would have used had that trigger not applied.
How it’s calculated
- ITR-1 (Sahaj) — for a resident individual with salary or pension, at most one house property and ordinary other income such as bank interest, where total income is within ₹50 lakh. It is the shortest form, and also the easiest to lose access to.
- ITR-2 — for an individual or HUF with no business or professional income, but with anything that rules out ITR-1: capital gains, more than one house property, total income above ₹50 lakh, foreign income or foreign assets, NRI or RNOR status, being a company director, holding unlisted shares, or agricultural income above ₹5,000.
- ITR-3 — for an individual or HUF carrying on a business or profession and maintaining books of account. Futures & options and intraday equity trading are business income, so they belong here, not in a capital-gains schedule. ITR-3 needs a profit & loss account and a balance sheet.
- ITR-4 (Sugam) — for a resident individual, HUF or firm (other than an LLP) declaring income on a presumptive basis under Section 58 of the Income-tax Act, 2025 (the old Sections 44AD and 44ADA), with total income within ₹50 lakh and none of the ITR-1 disqualifiers present.
- ITR-5 — for a partnership firm, LLP, AOP or BOI. None of the individual forms apply to these entities regardless of what they earn.
- ITR-6 — for a company, other than a company claiming exemption as a charitable or religious institution. It must be filed with a digital signature.
- ITR-7 — for a trust, NGO, society, political party, research institution or similar entity claiming exemption.
- The order of testing matters: entity type is decided first, then whether there is business or professional income, then whether the presumptive scheme applies, and only then whether any disqualifier knocks you out of the short form.
- Any single capital gain — one share sale, one SIP redemption, one ESOP exercise — removes ITR-1 for the whole year, no matter how small the amount.
Frequently asked questions
Can I file ITR-1 if I sold shares?
No. Any capital gain at all disqualifies ITR-1, however small. If you sold listed shares, redeemed even a single mutual-fund unit, switched between mutual-fund schemes (a switch is a redemption plus a fresh purchase, so it triggers a gain), or sold property, you must file ITR-2 — or ITR-3 if you also have business income. This is the most frequent reason returns are marked defective, because the gain often shows up only in the AIS and the taxpayer never noticed it.
Is F&O or intraday trading capital gains or business income?
Business income. Intraday equity trading is speculative business income and F&O is non-speculative business income — neither is a capital gain. That means ITR-3, with a profit & loss account and balance sheet, and a tax audit if turnover crosses the threshold. Reporting F&O losses in a capital-gains schedule is a common error that also costs you the ability to set off and carry forward those losses correctly.
I am a salaried employee but I hold RSUs of my company’s US parent. Which form?
ITR-2. Holding shares of a foreign company — RSUs, ESOPs or a foreign brokerage account — makes you a person with foreign assets, so you must disclose them in Schedule FA and you cannot use ITR-1. This applies even if you never sold a single share and even if the vested value is small. Non-disclosure of foreign assets carries penalties under the black-money law, so this one is worth getting right.
I am a freelancer. Should I file ITR-4 or ITR-3?
ITR-4 if you declare your professional receipts on a presumptive basis under Section 58 (the old 44ADA), your total income is within ₹50 lakh, and none of the disqualifiers apply — no capital gains, not more than one house, no foreign assets, not an NRI, not a director, no unlisted shares. If any of those apply, or if you would rather claim actual expenses and keep books because your real margin is lower than the presumptive rate, you file ITR-3 instead. Note that once you opt out of the presumptive scheme, you generally cannot re-enter it for the next five years.
What happens if I file on the wrong ITR form?
The return is treated as defective. The department issues a notice giving you a window to correct it, and if you do not respond in time the return is treated as never having been filed — which means late-filing fees, interest, and the loss of any right to carry forward losses. Even when you do respond, the revised return is processed from scratch, delaying your refund. Choosing the right form at the outset is far cheaper than fixing it afterwards.
I am an NRI with only rental income from a flat in India. Which form?
ITR-2. Non-resident and RNOR taxpayers cannot use ITR-1 or ITR-4 at all, regardless of how simple the income is — even a single rented flat with no other Indian income. ITR-2 also lets you report the residential-status details and claim any treaty relief and TDS credit correctly.
