Which ITR Form Should You File for AY 2026-27? ITR-1 vs ITR-2 vs ITR-3 vs ITR-4

Quick answer: Your ITR form depends on where your income comes from, not your job title. Salary/pension with simple income → ITR-1. Capital gains, multiple properties, or foreign assets but no business income → ITR-2. Business or professional income (regular books) → ITR-3. Business income under presumptive taxation → ITR-4. Filing the wrong one gets your return marked defective under Section 139(9) — which delays your refund and can trigger a notice.

Picking the wrong ITR form isn't a minor clerical slip. A defective return under Section 139(9) means the Centralised Processing Centre (CPC) bounces your filing back, you get a limited window to refile correctly, and in the meantime your refund clock doesn't start. Getting the form right the first time is worth the five minutes this guide takes.

Use ITR-1 if ALL of these are true:

• Total income does not exceed ₹50 lakh
• Income comes from salary/pension, at most one house property, and other sources like interest or family pension
• Agricultural income does not exceed ₹5,000
• Any long-term capital gains are limited to Section 112A gains (listed equity shares/equity mutual funds) up to ₹1.25 lakh, with no brought-forward losses to set off

You cannot use ITR-1 if you:

• Are a company director
• Hold unlisted equity shares at any point during the year
• Have any short-term capital gains
• Have foreign income or foreign assets
• Had tax deducted under Section 194N (large cash withdrawals)

The trap most people fall into: ITR-1 now technically allows a small amount of LTCG, but it's a narrow allowance. The moment your equity LTCG crosses ₹1.25 lakh, or you have any short-term capital gains at all — even ₹500 from a single mutual fund redemption — you're pushed to ITR-2, not ITR-1.

Use ITR-2 if you have no business/professional income and ANY of the following applies:

• Capital gains beyond what ITR-1 allows (any short-term gains, or LTCG above ₹1.25 lakh)
• More than one house property, or specific property situations ITR-1 doesn't cover
• Foreign income or foreign assets — including overseas bank accounts, foreign mutual funds, or ESOPs from a foreign parent company
• Total income above ₹50 lakh, even with otherwise simple income

If your only complication is investments, property, or holdings abroad — and you don't run a business — ITR-2 is your form.

Use ITR-3 if:

• You have business or professional income and maintain regular books of account (not using presumptive taxation)
• You're a partner in a firm receiving salary, interest, bonus, commission, or profit share — this counts as business income even if the amount is small, and requires ITR-3 regardless of how simple the rest of your income looks
• Your presumptive-taxation turnover has crossed the eligible threshold, forcing you out of ITR-4

This is the form for freelancers, traders, and professionals who track actual profit and expenses rather than using a flat presumptive rate.

Use ITR-4 if:

• You're a resident individual, HUF, or firm (excluding LLPs) computing business or professional income on a presumptive basis under Sections 44AD, 44ADA, or 44AE
• You prefer not to maintain detailed books of account
• Your turnover/receipts stay within the presumptive scheme's eligible limits

Important: if your turnover crosses the presumptive threshold during the year, you lose ITR-4 eligibility and must move to ITR-3 with full books of account — continuing to file ITR-4 anyway makes the return defective.
