The ITR-3 form is meant for individuals and Hindu Undivided Families (HUFs) who earn income through business or professional activities and are required to maintain books of accounts. This form is not meant for those without any business or professional income. However, salaried individuals with extra earnings from freelancing, trading, or part-time business may still need to file ITR-3 if business income is involved.

It covers a wide range of incomes, including salary, house property, capital gains, and other sources. Those earning from partnerships can also use this form to report their personal remuneration (though the partnership firm itself files separately using ITR-5). Individuals not having business income, or income from a firm, cannot use this form. This form is quite detailed and includes all income heads.

The last date to file ITR-3 depends on whether the taxpayer's accounts are subject to audit.

For the financial year 2025-26 (AY 2026-27), file online before 31 July 2026, filling out the ITR-3 form and verifying it via EVC/Aadhaar OTP. Always refer to the latest circulars for any extensions.

There are three ways to file the ITR-3 form:

1. Digital signature: Submit electronically using a digital signature (mandatory for audit cases)
2. Electronic Verification Code (EVC): Submit electronically using an EVC
3. Physical ITR-V: Submit online and send the signed physical ITR-V (verification) form to the Income Tax Department by post

Taxpayers required to undergo tax audit must file using a digital signature. Others may use either of the other two methods. In all cases, verify the return within the specified time to complete the filing process successfully.

Before filing ITR-3, understand who's eligible:

1. Individuals and HUFs: Those with income from a business or profession
2. Income sources: Suitable for those with income from proprietary businesses, professions, salary/pension, house property, capital gains, and other sources
3. Exclusions: ITR-3 is not applicable for individuals who are partners in a firm — they must use ITR-2 instead, since their partnership remuneration and share of profit are reported differently

Filing ITR-3 involves several components:

1. Personal information: Name, address, PAN, and Aadhaar
2. Income details: Comprehensive reporting from business/ profession, salary/ pension, house property, capital gains, and other sources
3. Deductions: Claims under sections like 80C and 80D
4. Tax computation: Calculation of total income and tax liability
5. Bank details: Information about all bank accounts held during the financial year
6. Verification: Self-declaration affirming accuracy of the information provided

Gather the following documents and details:

1. PAN and Aadhaar card — for identification and verification
2. Form 16 — if you have salary income
3. Bank statements — reflecting your income and expenses
4. Business/professional income details — income and expenditure details, profit and loss account, balance sheet
5. Investment proofs — supporting deduction claims under sections like 80C, 80D
6. Form 26AS — tax credit statement for the financial year

1. Check eligibility: Ensure you're eligible for ITR-3 — specifically for individuals and HUFs with income from a proprietary business or profession, alongside capital gains, multiple house properties, or other income sources
2. Gather relevant documents: Arrange PAN card, Aadhaar card, bank account details, income and expense details, balance sheet and profit & loss account details, Form 26AS, and tax-saving investment proofs
3. Visit the Income Tax e-filing portal: Log in using your user ID (PAN), password, and captcha
4. Select 'Filing of Income Tax Return': Click 'e-file,' select this option from the dropdown, and select 'ITR-3' as the ITR form name
5. Complete the form: Fill in personal information, current address, your business/profession code, income details, deductions, and tax details
6. Fill Schedule BP: This section requires the most detail — trading account, manufacturing account, profit & loss account, and balance sheet details
7. Validate information: The portal auto-calculates total income and tax; cross-check against your supporting documents
8. Pay tax and submit: Pay off any outstanding tax, submit your ITR form, and receive an acknowledgment number
9. E-verify your ITR: Via Aadhaar OTP, EVC (bank account, demat account, net-banking), or by sending a signed ITR-V through post
