ITR Filing Basics: What You Need to Know

Which Form Applies to You

Form	Typical Use Case	Note
ITR-1 (Sahaj)	Salary + 1 house property + interest income	Simplest form, most salaried filers
ITR-2	Capital gains, multiple properties, foreign assets	Common once you sell stocks/mutual funds
ITR-3	Business or professional income	Freelancers, proprietors, F&O traders
ITR-4 (Sugam)	Presumptive business/professional income	Simplified filing under presumptive schemes

💡 Even one stock or mutual fund sale during the year usually bumps a salaried filer from ITR-1 to ITR-2 — check this before assuming you can keep using last year's form.

Why File Even If No Tax Is Due

Clean financial record

Useful for loan applications, credit cards, and visa processing, which often ask for the last 2-3 years of ITRs as income proof.

Carry forward losses

Missing the deadline can mean losing the ability to carry forward certain losses (like capital losses) to offset gains in future years.

Claim a refund

If TDS deducted through the year exceeds your actual liability, filing is the only way to get that excess amount back.

Avoid late fees

Filing after the due date can attract a late fee even when no additional tax is owed, purely for missing the deadline.

Documents to Keep Ready

Form 16

From your employer, summarizing salary, TDS, and declared deductions for the year.

Bank interest certificates

Interest earned on savings accounts and fixed deposits, which counts as taxable income.

Capital gains statements

From your broker or mutual fund platform, detailing gains/losses on any stocks or funds sold.

Deduction proofs

Insurance receipts, investment proofs, and home loan interest certificates for whatever you're claiming.

Frequently Asked Questions

What happens if I miss the ITR filing deadline?⌄

You can typically still file a "belated return" after the deadline, but it usually comes with a late fee, possible interest on any unpaid tax, and restrictions on carrying forward certain losses.

Can I revise my ITR after filing if I made a mistake?⌄

Yes — a revised return can typically be filed to correct errors or omissions, within a specified window after the original filing. It's a normal part of the process and not treated as a red flag by itself.

Do I need to file if my income is below the taxable limit?⌄

Filing isn't always mandatory below the basic exemption limit, but certain conditions (like large bank deposits, foreign travel spending, or high electricity bills) can still require you to file. Filing voluntarily is also often worthwhile for the record-keeping benefits.

Can I file my ITR myself, or do I need a CA?⌄

Simple cases (ITR-1, straightforward salary income) are often manageable on your own through the income tax e-filing portal. More complex situations — business income, multiple capital gains transactions, foreign assets — are usually worth a CA's help to avoid errors.
