Before You Start — What is ITR?
An Income Tax Return (ITR) is a form you submit to the Income Tax Department declaring your income, deductions, and tax paid during the financial year. Even if your employer deducts TDS, you still need to file a return if your gross income exceeds the basic exemption limit.
✅ Filing ITR has benefits beyond compliance: It serves as proof of income for visa applications, home loans, credit cards, and government tenders.
Which ITR Form Should You Use?
| Form | Who Should Use It |
|---|---|
| ITR-1 (Sahaj) | Salaried individuals with income up to ₹50 lakh. One house property, no business income. |
| ITR-2 | Individuals/HUF with capital gains, more than one property, or foreign assets. |
| ITR-3 | Individuals with income from business or profession. |
| ITR-4 (Sugam) | Freelancers and small business owners opting for presumptive taxation. |
Most salaried individuals use ITR-1. If you have stocks or mutual fund gains, use ITR-2.
