Wrong ITR Form? You Could Get a Tax Notice

For AY 2026-27, you must pick the correct ITR form based on how you earn money. Filing the wrong form makes your return defective, which can trigger an income tax notice even if you paid all your taxes correctly.

Here's what happened: The Income Tax Department has 7 different ITR forms for AY 2026-27, each designed for a specific taxpayer type and income source.. Filing the wrong ITR form — even accidentally — makes the return 'defective' under Section 139(9), and you get a notice to refile.. ITR-1 and ITR-4 cover most salaried and small business filers, but new income sources like capital gains now disqualify many from these simpler forms..

What you should do: Check your Form 26AS and AIS on the income tax portal to list every income source before picking any ITR form — salary, rent, dividends, capital gains all matter.. If you sold mutual funds or stocks in FY 2025-26, avoid ITR-1 entirely — use ITR-2 even if your salary is your primary income.. Small business owners and freelancers using the presumptive taxation scheme (Section 44AD/44ADA) must file ITR-4, not ITR-1 — confirm eligibility before submitting..

Pro tip: If your employer's Form 16 shows only salary but your AIS shows even ₹1 of capital gains or dividend above ₹10 lakh, the tax department already knows — file ITR-2 or face a mismatch notice.
