Frequently Asked Questions
1. Can a taxpayer file ITR-4 after opting out of the presumptive taxation scheme?
No. A taxpayer who is not eligible for the presumptive taxation scheme or has opted out in circumstances where the scheme’s lock-in provisions apply must file the applicable ITR form, such as ITR-3, subject to the provisions of the Income Tax Act, 2025.
2. Is filing an Income Tax Return mandatory even if tax has been deducted at source (TDS)?
Yes. Deduction of TDS does not exempt a taxpayer from filing an Income Tax Return where filing is mandatory under the Income Tax Act, 2025. Taxpayers must independently satisfy the prescribed return filing conditions.
3. Can a mismatch between the books of account and the Income Tax Return trigger scrutiny?
Yes. Material discrepancies between the books of account, financial statements, AIS, Form 168, TDS returns, or the Income Tax Return may increase the likelihood of notices, verification, or scrutiny proceedings.
4. What are the compliance implications of reporting incorrect turnover in ITR-3 or ITR-5?
Incorrect turnover reporting may affect the computation of taxable income, audit applicability, presumptive taxation eligibility, and other statutory compliances. It may also lead to reassessment or demand notices.
5. Is reconciliation of AIS, Form 168, and TDS certificates mandatory before filing the Income Tax Return?
While not expressly mandatory, reconciliation is a critical compliance practice. Any mismatch in income, TDS, or specified financial transactions may result in processing delays, reduced refunds, or notices from the Income Tax Department.
6. Can a taxpayer revise the method of income reporting after filing the original return?
Yes, where permitted under the Income Tax Act, 2025, a revised return may be filed to rectify omissions or incorrect particulars. However, changing the method of reporting should be supported by proper books of account and documentary evidence.
7. Does filing ITR-5 automatically mean that the entity is subject to tax audit?
No. Filing ITR-5 and applicability of a tax audit are separate compliance requirements. Audit applicability depends on factors such as turnover, gross receipts, business activity, and the provisions governing tax audit under the Income Tax Act, 2025.
8. What are the compliance risks of failing to report specified financial transactions?
Failure to disclose taxable income arising from reportable financial transactions reflected in the Annual Information Statement (AIS) may result in notices, reassessment proceedings, interest, penalties, or prosecution, depending on the nature and extent of the default.
9. How should taxpayers determine whether ITR-3 or ITR-5 is the correct return form?
The applicable ITR form is determined based on the legal status of the taxpayer (individual, HUF, firm, LLP, AOP, BOI, etc.), the nature of income, and the provisions of the Income Tax Act, 2025. Filing an incorrect form may render the return defective or invalid.
10. How can Ebizfiling help businesses manage complex Income Tax compliances?
Ebizfiling assists businesses with return preparation, tax reconciliations, compliance reviews, form selection, documentation support, and end-to-end Income Tax compliance to ensure accurate reporting and timely statutory filings.
