Filing income tax returns (ITR) is not just a legal obligation — it's in your financial interest. ITR filing builds your financial track record, is required for visa applications, loan approvals, and helps you claim tax refunds. Yet millions of Indians who should file don't — either out of confusion or fear of complexity.
This guide explains India's income tax system in plain language, helps you choose between new and old regimes, and walks you through filing your ITR online.
Who Must File ITR in India?
You must file ITR if:
- Your total income exceeds ₹2.5 lakh (₹3 lakh for senior citizens aged 60–79; ₹5 lakh for super-seniors above 80)
- You earned foreign income or hold foreign assets
- You had TDS deducted and want a refund
- You made deposits of ₹50 lakh+ in savings account in a year
- You want to carry forward capital loss to offset future gains
Income Tax Slabs India 2026 (New Regime — Default)
| Income Range | New Regime Tax Rate |
|---|---|
| Up to ₹3 lakh | Nil |
| ₹3–7 lakh | 5% |
| ₹7–10 lakh | 10% |
| ₹10–12 lakh | 15% |
| ₹12–15 lakh | 20% |
| Above ₹15 lakh | 30% |
Rebate: Under Section 87A, if your taxable income is up to ₹7 lakh under the new regime, you get a full tax rebate — effectively paying zero tax up to ₹7 lakh.
New Regime vs Old Regime — Which to Choose?
The new regime is simpler (fewer deductions) but may not always save you more tax. The old regime allows deductions that can reduce your taxable income significantly.
| Aspect | New Regime (Default) | Old Regime (Optional) |
|---|---|---|
| Standard Deduction | ₹75,000 (salaried) | ₹50,000 |
| Section 80C (₹1.5 lakh) | Not available | Available |
| HRA exemption | Not available | Available |
| Home loan interest (80C) | Not available | Up to ₹2 lakh deductible |
| NPS (80CCD) | Partial (employer contribution only) | Full 80CCD deduction |
| Simplicity | Simple — fewer calculations | Complex — requires tracking investments |
General rule: If your total deductions (80C + HRA + home loan etc.) exceed ₹2–3 lakh, the old regime may save more tax. Calculate both and choose. Your employer or an ITR portal will help you compare.
