ITR Deadline August 31: ITR-3 vs ITR-4, Eligibility, Documents and Filing Rules Explained

The deadline to file income tax returns for the current assessment year is fast approaching on August 31 for individuals, professionals, and small business owners whose accounts do not require a tax audit. Taxpayers earning income from freelancing, consulting, proprietorships, or partnerships must complete their filings using either the ITR-3 or ITR-4 (Sugam) form to avoid penalties and interest charges.

Following the initial July 31 deadline, which saw over 6.5 crore returns submitted, primarily by salaried individuals and non-business taxpayers, the August 31 window specifically caters to non-audit business and professional income. Taxpayers whose accounts are subject to a mandatory tax audit have until October 31 to complete their filings.

Choosing The Correct Form: ITR-3 vs ITR-4

Selecting the correct tax return form is critical, as filing under the wrong form can render the return defective. ITR Filing: What if You Miss the August 31 Deadline? Check Penalty and Belated Return Rules.

When To Use ITR-3

The ITR-3 form is mandatory for individuals and Hindu Undivided Families (HUFs) carrying on a business or profession who do not opt for the presumptive taxation scheme.

Key criteria include maintaining formal books of account, having a total income exceeding INR 50 lakh, reporting income from Futures and Options (F&O) or intraday equity trading, and reporting income across multiple heads, including salary, house property, business profits, capital gains, and other sources, where the filer is ineligible for ITR-1, ITR-2, or ITR-4. Income Tax Refund Status: When Will You Get Your ITR Refund for AY 2026–27?

When To Use ITR-4 (Sugam)

The ITR-4 form is a simplified return intended for resident individuals, HUFs, and partnership firms opting for the presumptive taxation scheme under Sections 44AD, 44ADA, or 44AE.

Key criteria include total income of up to INR 50 lakh during the financial year, income derived from an eligible business or profession declared on a presumptive basis alongside salary, up to two house properties, and other standard sources such as interest or dividends, and agricultural income not exceeding INR 5,000.

Taxpayers cannot use ITR-4 if they hold directorships in a company, own unlisted equity shares, have foreign assets or foreign sourced income, carry forward business losses, or have capital gains exceeding statutory limits under Section 112A.

Pre-Filing Checklist And Documentation

Before initiating the filing process on the Income Tax Department's e-filing portal, taxpayers should reconcile their financial records against pre-filled data. Key documents include Form 26AS, Annual Information Statement (AIS), and Taxpayer Information Summary (TIS); Form 16A for professional receipts, Form 16 if salary income is present, and bank account interest certificates.

For ITR-3, filers additionally need Profit and Loss account, Balance Sheet, Trial Balance, fixed asset registers, and turnover records. Statutory reconciliations such as GST returns matched against reported turnover, sales or purchase registers, and payment gateway statements are also required, along with investment and property records including demat transaction statements, capital gains summaries, home loan interest certificates, and municipal tax receipts.

How To File And Verify

Taxpayers can complete the filing process directly through the official e-filing portal, eportal.incometax.gov.in, using their Permanent Account Number (PAN) credentials.

After reviewing pre-filled data, reporting all income heads, claiming eligible deductions, and settling any self-assessment tax dues, the return must be e-verified, using Aadhaar OTP, net banking, or electronic verification codes (EVC), within the stipulated window to complete the process. Filers may also engage registered Chartered Accountants or authorised e-return intermediaries to submit their documentation.
