You may have to file even with no tax to pay
Filing is not the same as paying. There are situations where a return is required regardless of whether any tax is due, and people miss this because their employer already deducted TDS.
- Your total income before deductions exceeds the basic exemption limit.
- You want a refund of TDS that was over-deducted — you cannot get one without filing.
- You hold foreign assets or have signing authority over a foreign account.
- You meet any of the specified high-value transaction conditions, which include large deposits, large electricity bills and foreign travel spending above thresholds.
- You want to carry forward a loss to set against future income. This is only possible if the return is filed by the due date.
Which ITR form applies
Choosing the wrong form results in a defective return, which you then have to correct within a limited window. The portal now suggests a form based on your answers, and that suggestion is usually right — but it depends on the information you give it.
If you have capital gains, ITR-1 does not apply, however simple the rest of your income is. This is the most common misfiling.
| Form | Broadly for |
|---|---|
| ITR-1 (Sahaj) | Resident individuals with salary or pension, one house property and other income, within the prescribed income ceiling |
| ITR-2 | Individuals and HUFs without business or professional income — includes capital gains and more than one house property |
| ITR-3 | Individuals and HUFs with income from business or profession |
| ITR-4 (Sugam) | Presumptive income under sections 44AD, 44ADA or 44AE, within the prescribed ceiling |
Before you file
- Confirm your PAN is linked to Aadhaar. An inoperative PAN cannot be used to file.
- Pre-validate a bank account on the portal — refunds are only issued to a pre-validated account.
- Download Form 26AS and the Annual Information Statement from the portal.
- Reconcile the TDS in your Form 16 against Form 26AS. They should match exactly.
- Check the AIS for interest, dividends and transactions you may have forgotten. Income reported there and missing from your return is what generates a notice.
- Decide your regime. The one your employer applied for TDS is not binding on you at filing.
File, then verify
- Log in to incometax.gov.in and choose e-File → Income Tax Return.
- Select the assessment year and the form.
- Much of the return is pre-filled from Form 26AS and the AIS. Check every pre-filled figure rather than trusting it.
- Add anything missing, claim your deductions, and confirm the tax computed.
- Submit.
- E-verify within 30 days — by Aadhaar OTP, net banking, a demat account, or by posting a signed ITR-V to the CPC.
