Common Income Tax Return Filing Mistakes in India

1. Bank interest and fixed deposits

Report savings-account interest, fixed-deposit interest, recurring-deposit interest and other taxable interest under the correct head of income. Tax deducted at source (TDS) is a credit against final tax, not an exemption. Verify interest certificates and Form 26AS, AIS and TIS. Section 80TTA or 80TTB deductions, where eligible, depend on the applicable tax regime and statutory conditions.

2. Omitting one or more bank accounts

Disclose all reportable bank accounts in the income-tax return and reconcile interest across them. An account may need to be reported even when it produced little or no taxable interest; follow the instructions for the selected ITR form.

3. Large cash deposits without supporting records

Cash deposits are not automatically taxable income, but the taxpayer should be able to explain the source with contemporaneous evidence. Relevant provisions may include sections 68, 69, 69A and 115BBE of the Income-tax Act, 1961, depending on the facts. Cash receipt and repayment restrictions under sections 269SS, 269ST and 269T may also apply.

4. Unexplained credit-card payments

Reconcile credit-card expenditure and repayments with bank statements, business records and disclosed sources. A high-value payment is not by itself proof of undisclosed income, but unexplained funding may invite questions.

5. Share investments, trading and dividends

Maintain contract notes, demat statements, purchase cost, sale proceeds and brokerage records. Determine whether transactions generate capital gains or business income on the facts; disclose dividends and other investment income separately. Securities transaction tax and TDS entries do not replace income reporting.

6. Property sales and capital gains

Report property transfers and compute capital gains using the applicable provisions, including sections 45, 48 and 50C where relevant. Exemptions under sections 54, 54F or 54EC have distinct eligibility rules, investment ceilings and deadlines. Do not assume every property purchase within two years qualifies; check the specific section and the applicable assessment year.

7. Expenses without invoices or evidence

Claim business expenses only when allowable and properly substantiated. Section 37(1) generally concerns expenditure laid out wholly and exclusively for business or profession, subject to exclusions; other provisions govern specific expenses and cash payments. Lack of a matching cash withdrawal alone does not prove an expense is false.

8. Leaving out cash receipts or part of income

Reconcile invoices, cash books, payment-platform statements, Form 16, Form 16A, AIS and other records. Report income according to the applicable accounting and tax rules; omissions can lead to tax, interest and statutory proceedings.

9. Claiming the same expense twice

Avoid claiming a single cost more than once or in both personal and business computations without a lawful basis. Maintain supporting bills and an audit trail.

10. Ignoring AIS, TIS and Form 26AS

Compare the Annual Information Statement (AIS), Taxpayer Information Summary (TIS), Form 26AS, Form 16 and Form 16A with your own records. AIS data can be incomplete or incorrect; submit feedback where appropriate and report income based on the law and underlying facts.

11. Selecting the wrong ITR form

Choose the form based on income sources, residency, business activity, capital gains and other eligibility criteria for the relevant assessment year. Using an ineligible form may result in a defective return notice under section 139(9).

12. Advance tax and self-assessment tax

Review advance-tax obligations under sections 207 to 211 and applicable interest provisions, including sections 234B and 234C. Pay outstanding self-assessment tax and applicable interest before filing.

13. Missing the filing deadline or failing to verify

File within the due date applicable under section 139(1), verify the return within the prescribed period and keep the acknowledgement. Belated returns under section 139(4) and revised returns under section 139(5) are possible within statutory limits; the earlier blanket statement that a late return cannot be revised is outdated. Late-filing fees under section 234F and interest under section 234A may apply.

Before submitting your ITR: practical checklist

• Match salary, business, interest, dividends and capital gains against underlying records.
• Review AIS, TIS, Form 26AS and TDS certificates; resolve discrepancies.
• Reconcile bank accounts, cash transactions and credit-card repayments.
• Check the selected tax regime, deductions, losses and applicable ITR form.
• Confirm tax payments, filing deadlines and successful e-verification.

Frequently asked questions

Is TDS on fixed-deposit interest the final tax?

No. Report taxable interest and claim eligible TDS credit; the final liability depends on total income and applicable law.

Can a belated income-tax return be revised?

Yes, a belated return filed under section 139(4) can generally be revised under section 139(5) within the applicable statutory time limit.

Are all large cash deposits taxable?

No. Their tax treatment depends on the source and evidence. Unexplained amounts may attract provisions dealing with unexplained credits or money.
