The short answer
Which ITR does a sole proprietor file?
Quick answer
Usually ITR-3 or ITR-4. ITR-3 is the regular business-income return for an individual or HUF not eligible for a simpler form. ITR-4 is optional for an eligible resident declaring qualifying business income on a presumptive basis. The correct choice depends on your income sources, turnover, cash receipts, losses and whether you want to claim actual expenses.
Generally relevant when ITR-4 does not fit, or when actual income, expenses, assets, liabilities or losses must be reported through regular business schedules.
Normally no separate deduction after presumptive profit
Yes, subject to tax rules and records
Business loss to report or carry forward?
Usually not the appropriate route

AY 2026-27 deadline
Non-audit business returns are due 31 August 2026
A proprietorship that requires an audit follows a different timeline. Do not assume that turnover alone settles audit applicability; profit declaration, cash levels and other facts can matter.
31 August 2026
Current due date for AY 2026-27 business or professional income cases not requiring audit. Audit cases are generally due 31 October 2026.
A sole proprietor generally files ITR-3 when reporting regular business income and actual expenses. ITR-4 may be available to an eligible resident opting for presumptive taxation under Section 44AD, subject to all conditions and exclusions.
The due date for a non-audit business return for AY 2026-27 is 31 August 2026. Audit and transfer-pricing cases follow different due dates.
A sole proprietorship is not a separate income-tax person from its proprietor. Business income is normally reported using the proprietor's PAN in the applicable individual return.
A difference is not automatically an error, but it should be explained and reconciled—for example through GST components, returns, advances, transfers or timing differences—before the return is filed.
Eligible ITR-4 presumptive filing is Rs.1,499 and ITR-3 with the currently published regular-books scope is Rs.2,999. Accounting, audit, notice or complex computation work is quoted before it begins.
