What Is ITR-3?

ITR-3 is an Income Tax Return form generally applicable to individuals and HUFs having income from business or profession.

The form allows eligible taxpayers to report income from multiple sources, including:

• Salary or pension
• Income from house property
• Profits and gains from business or profession
• Capital gains
• Income from other sources
• Eligible foreign income and asset disclosures, where applicable

ITR-3 is a detailed return form because business and professional taxpayers may need to provide information relating to profit and loss, balance sheet items, business income, expenses, depreciation, tax payments, and other applicable disclosures.

The official Income Tax Department guidance identifies ITR-3 as applicable to eligible individuals and HUFs having income from business or profession.

ITR-3 is not the appropriate form for every taxpayer.

For example:

• Individuals with only simple salary income may be eligible for another ITR form.
