    Just as partnerships and corporations are obligated to pay taxes on their earnings, so too must sole proprietorships. Legally, the proprietorship is considered an extension of the owner, meaning the tax filing process mirrors that of the individual owner. Consequently, the same tax regulations that apply to the owner’s income tax also apply to the business. Proprietorship Tax Return Filing is also as important as others. 

    Audit Requirements for Proprietorships

    Sole proprietorships may be required to undergo an audit based on specific revenue thresholds and other conditions.

    Revenue-Based Audit Requirement: An audit is mandatory for a sole proprietorship if its annual turnover exceeds ₹1 crore in a fiscal year. This threshold applies to businesses engaged in trade, manufacturing, or any other commercial activities. For sole proprietorships providing professional services, the audit requirement is triggered when the annual receipts exceed ₹50 lakh. In both cases, the audit ensures that the financial statements accurately reflect the business’s financial position and comply with statutory requirements.

    Presumptive Taxation Scheme Audit Requirement: Sole proprietorships that are enrolled in any presumptive taxation scheme under sections 44AD, 44ADA, or 44AE of the Income Tax Act, 1961, must also undergo an audit. This requirement applies irrespective of the turnover or gross receipts. The presumptive taxation scheme allows businesses to declare income at a prescribed rate without maintaining detailed accounts. However, if the proprietor’s declared income is lower than the presumptive income and exceeds the basic exemption limit, an audit becomes necessary to validate the financial claims.

    Compliance with Income Tax Act Requirements: As mandated by the Income Tax Act, 1961, audits must adhere to the specified regulations and guidelines. A qualified Chartered Accountant (CA) must conduct these audits. The CA is responsible for examining the financial records to ensure their accuracy and completeness. They also verify that the business complies with all applicable statutory obligations, including the proper maintenance of books of accounts and other relevant financial documentation.

    Qualified Chartered Accountant’s Role: The CA plays a crucial role in the audit process. They are responsible for conducting a thorough examination of the financial statements, internal controls, and accounting practices of the sole proprietorship. The CA ensures that the financial records are accurate and reflect the true financial status of the business. They also provide recommendations for improving financial management and ensuring compliance with all regulatory requirements. The CA’s audit report is submitted along with the tax return to the Income Tax Department, providing assurance of the business’s financial integrity.

    Verification of Audit Conditions: Sole proprietors must regularly verify whether their business meets any of the conditions that necessitate an audit. This involves monitoring turnover, professional receipts, and participation in presumptive taxation schemes. If any of these conditions apply, the proprietor must ensure that an audit is conducted in accordance with the stipulated guidelines and within the prescribed timelines.


    Any individual who runs a proprietorship business must file their income tax returns. The tax filing deadline for proprietorship businesses is usually July 31st of every year, but it may be extended in some cases.

    Guidelines for e-Filing Income Tax Returns for Sole Proprietorships

    Choose ‘Income Tax Return’ from the E-filing Menu: Once logged in, navigate to the ‘E-file’ menu and select ‘Income Tax Return.’ This will initiate the process of filing your return online.

    Select the Appropriate Options on the Form: On the income tax return form, you will need to make several selections: choose the assessment year for which you are filing the return, select the appropriate ITR form number based on your income sources (for sole proprietorships, this is typically ITR-3 or ITR-4), indicate whether you are filing an original return or a revised return if you are correcting any errors in a previously filed return, and opt for the ‘prepare and submit’ mode to fill out the form online.

The options include immediate e-verification (authenticate your return instantly using an OTP or EVC sent to your registered mobile number or email), e-verify later (you can choose to e-verify your return within 120 days of filing it), or manual verification (if you opt out of e-verification, you will need to send a signed physical copy of the ITR-V to the Centralised Processing Centre within 120 days).

    Filing Income Tax Returns for a Sole Proprietorship

    Form ITR-4 Sugam: For proprietorships under presumptive taxation, simplifying compliance for small enterprises. The proprietorship’s income is integrated with the proprietor’s personal income, making business taxes equivalent to personal taxes. The proprietor retains eligibility for all individual or HUF tax deductions.
