Income tax filing errors are usually avoidable. They happen because taxpayers rush, rely only on Form 16, ignore AIS, or choose a form without checking their full income profile.
This guide explains the mistakes MyeCA is designed to catch early.
1. Choosing the wrong ITR form
ITR-1 is not valid for every salaried person. If you have capital gains, foreign assets, certain high-value income, or multiple house properties, you may need another form.
2. Ignoring AIS and TIS
AIS may show interest, securities transactions, dividends, foreign remittances, and other reported data. Ignoring it can create mismatches later.
3. Claiming TDS that is not visible in Form 26AS
Your employer or client may have deducted tax, but if it is not correctly deposited or mapped, the credit may not appear. Always reconcile before filing.
4. Missing interest income
Savings and FD interest are taxable even when TDS is not deducted. Many taxpayers miss small amounts across multiple accounts.
5. Incorrect HRA claim
HRA needs rent, salary structure, city classification, and landlord details. If annual rent crosses the reporting threshold, landlord PAN may be required.
6. Duplicate deduction claims
Some investments appear in employer declarations and personal proofs. Claiming twice can distort the return.
7. Forgetting previous employer income
If you changed jobs, both employers may have calculated tax independently. You must consolidate salary and TDS.
8. Incorrect refund bank account
A refund can fail if the bank account is not pre-validated, inactive, or mapped incorrectly.
9. Not reporting capital gains correctly
Equity, mutual funds, property, and crypto need careful classification and date-wise reporting.
10. Ignoring advance tax liability
Freelancers, business owners, and investors may need advance tax. Missing it can create interest under Sections 234B and 234C.
11. Missing foreign asset reporting
Foreign shares, bank accounts, ₹Us, and ESOPs may require specific disclosures. This is a high-risk area.
12. Filing without reviewing notices
Past adjustments can affect the current return. If you received a notice, refund adjustment, or demand, review it before filing.
13. Waiting until the deadline
Late filing increases mistakes and reduces time for CA review. It can also affect carry-forward of some losses.
14. Not saving the final computation
The acknowledgement alone is not enough. Save the final computation, ITR copy, challans, working papers, and supporting documents.
15. Not asking for help when facts are complex
Capital gains, business income, foreign assets, and notices are not ideal unreviewed cases. CA review can prevent expensive corrections.
