Proprietorship ITR Filing (ITR-3 / ITR-4)

The choice depends on the taxation scheme opted by the proprietor. ITR-4 (Sugam) is applicable where the proprietor opts for presumptive taxation under Section 44AD for traders (turnover up to Rs 2 crore), Section 44ADA for specified professionals (gross receipts up to Rs 50 lakh), or Section 44AE for transporters. If the proprietor maintains regular books of accounts or the turnover exceeds these limits, ITR-3 must be filed. Both forms also accommodate income from house property, capital gains, and other sources.

For proprietors not requiring a tax audit, the due date is 31 July of the assessment year. For those requiring a tax audit under Section 44AB — turnover exceeding Rs 1 crore for business or Rs 50 lakh for profession — the due date is 31 October. Where the proprietor has international transactions requiring a transfer pricing report, the due date extends to 30 November. These dates are subject to extension by the Central Board of Direct Taxes through official notifications.

A tax audit under Section 44AB is mandatory if your business turnover exceeds Rs 1 crore in a financial year (Rs 10 crore if cash transactions are less than 5 percent of total transactions). For professionals, the threshold is Rs 50 lakh gross receipts. If you opt out of the presumptive scheme under 44AD after having opted in for one or more earlier years, a tax audit becomes compulsory for the next five years regardless of turnover.

Late filing attracts a penalty under Section 234F — Rs 5,000 if filed before 31 December of the assessment year, or Rs 1,000 if total income does not exceed Rs 5 lakh. Interest at 1 percent per month under Section 234A applies on the outstanding tax from the due date. Additionally, losses under the head 'Profits and Gains of Business or Profession' and 'Capital Gains' cannot be carried forward if the return is filed after the due date.

Yes. Where a proprietor uses a portion of the home exclusively for business purposes, a proportionate share of rent, electricity, internet, and maintenance expenses can be claimed as a business deduction. The deduction must be reasonable and supported by documentary evidence. If the proprietor owns the home, notional rent cannot be charged, but depreciation on the business portion of the building can be claimed under the Income Tax rules as applicable.

The Income Tax Department matches turnover reported in the ITR with GST returns filed on the GSTN portal. Differences arise due to exempted supplies, advances received, credit notes, and composition scheme transactions. A reconciliation statement should be prepared before filing, explaining each difference. The Annual Information Statement on the income tax portal now displays GST turnover as reported by GSTN, making reconciliation mandatory for a clean filing.

Under Section 44AD, an eligible assessee (resident individual, HUF, or partnership firm other than LLP) engaged in any business with turnover not exceeding Rs 2 crore can declare income at 8 percent of total turnover or gross receipts. Where receipts are through digital modes (banking channels, cheque, or digital payment), the rate is 6 percent. The deemed income covers all business expenses, and the assessee is not required to maintain detailed books of accounts for that business.

E-verification can be completed without sending a physical ITR-V. The methods available are: Aadhaar-linked OTP (Aadhaar must be linked to PAN), electronic verification code through net banking for authorised banks, EVC through the Demat account, or through the bank account registered on the portal. Alternatively, the signed physical ITR-V can be sent by speed post to CPC Bengaluru within 30 days of filing. Digital signature is also accepted for taxpayers who have a registered DSC on the portal.

Yes. A revised return can be filed under Section 139(5) of the Income Tax Act at any time before the completion of assessment or before the end of the relevant assessment year, whichever is earlier. For Assessment Year 2025-26, a revised return can be filed up to 31 March 2026. There is no monetary penalty for filing a revised return, but interest under Section 234B may apply if the revision results in additional tax liability.
