ITR Filing — Sole Proprietor / Business Income

Filing basis under the Income-tax Act, 1961. A sole proprietor is assessed as an individual; the applicable ITR form depends on how business income is computed, not on the existence of the proprietorship itself.

Presumptive taxation under Section 44AD (eligible businesses): available where turnover does not exceed ₹2 crore, extended to ₹3 crore where cash receipts do not exceed 5% of total turnover; taxable income is deemed to be 8% of turnover (6% for receipts through banking/digital modes). LLPs cannot use Section 44AD.

Presumptive taxation under Section 44ADA (specified professionals — legal, medical, engineering, architecture, accountancy, technical consultancy, and similar): available where gross receipts do not exceed ₹50 lakh, extended to ₹75 lakh where at least 95% of receipts are through banking/prescribed electronic modes; taxable income is deemed to be 50% of gross receipts.

Form selection: proprietors opting for Section 44AD, 44ADA, or 44AE presumptive income file ITR-4 (Sugam), provided total income does not exceed ₹50 lakh. Proprietors who opt out of the presumptive scheme, whose income exceeds the ITR-4 total-income ceiling, or who are subject to a Section 44AB tax audit must file ITR-3 with full books of account (and audit report, where applicable).

A proprietor who declares income below the presumptive rate and whose total income exceeds the basic exemption limit is required to maintain books of account and obtain a tax audit under Section 44AB(e), regardless of turnover.

Income tax return filing for a sole proprietor covers the return of the individual's business income under the Income-tax Act 1961 — the profits computed under Sections 28 to 44DB, the presumptive taxation under Section 44AD for the small businesses, the deductions of Sections 30 to 37 and Chapter VI-A, the books and the audit under Section 44AB where the turnover crosses the threshold, and the return filed in ITR-3 or ITR-4 under Section 139(1). For the proprietor, the business income and the personal income are one return.

The proprietor's return is where the business and the personal positions meet — the business income computed under the Act, the other income from the property, the capital gains and the investments, and the deductions spread across both. The presumptive regime of Section 44AD offers the small business a simplified income at the prescribed percentage, and the choice between the presumptive and the actual computation is a real tax decision.

The cost of a mismanaged proprietorship return is the assessment risk: the expenses claimed without the records, the presumptive scheme misapplied, the audit threshold crossed without the audit — each a disallowance at the assessment with the interest. The proprietor's return is also the record the business runs on, so its accuracy matters beyond the tax.

This service is for sole proprietors of every size. We compute the business income under the Act, apply the presumptive regime of Section 44AD or the actual computation, prepare the audit report under Section 44AB where required, prepare and file the return in ITR-3 or ITR-4, and handle the scrutiny and the assessments so the proprietor's business and personal positions are right.
