📖Overview

Filing an Income Tax Return (ITR) is a legal obligation for every Indian whose income exceeds the basic exemption limit (₹3 lakh under Old Regime, ₹3 lakh under New Regime for FY 2025-26). Even if your income is below the limit, filing ITR is recommended — it serves as income proof for loans, visa applications, and claiming tax refunds.

There are 7 ITR forms: ITR-1 (Sahaj) for salaried with income up to ₹50 lakh, ITR-2 for capital gains/multiple properties, ITR-3 for business income, ITR-4 (Sugam) for presumptive income, and ITR-5/6/7 for firms and companies. Most salaried employees use ITR-1 or ITR-2.

The income tax e-filing portal (incometax.gov.in) allows free online filing. Most of your data (salary, TDS, bank interest) is pre-filled from Form 16, Form 26AS, and AIS (Annual Information Statement). For simple salaried cases, filing takes just 15-20 minutes.

The deadline for individuals is July 31 of the assessment year (for income earned in the previous financial year). Filing after the deadline attracts a penalty of ₹5,000 (reduced to ₹1,000 if income is below ₹5 lakh). You also lose the ability to carry forward certain losses if you file late.

📝Step-by-Step: Filing ITR-1 Online (for Salaried)

1
Login to incometax.gov.in
Visit the e-filing portal. Login with PAN number as User ID and your password. If first time, register using PAN, Aadhaar, and mobile number. Complete profile setup.
2
Go to e-File → Income Tax Returns → File ITR
Select Assessment Year 2026-27 (for income earned in FY 2025-26). Select ITR-1 (if salaried with income ≤₹50 lakh, one house property). Select 'Online' filing mode.
3
Choose tax regime — Old vs New
Critical choice: Old regime allows deductions (80C, 80D, HRA) but has higher tax rates. New regime has lower rates but almost no deductions. The portal shows a comparison. Generally: If deductions > ₹3-4 lakh, Old regime is better. Otherwise, New regime saves more tax.
4
Verify pre-filled data
The portal auto-fills your salary, TDS deducted, bank interest, and other income from Form 26AS and AIS. VERIFY every number against your Form 16 and bank statements. If anything is wrong, edit it. Common error: Bank interest income is pre-filled but often missed by people.
5
Enter deductions (if Old Regime)
Claim deductions under: 80C (PPF, ELSS, EPF, insurance — up to ₹1.5L), 80D (health insurance premium — up to ₹25K self + ₹25K parents), 80CCD(1B) (NPS — extra ₹50K), HRA exemption, home loan interest (Section 24 — up to ₹2L). Enter investment amounts in the respective fields.
6
Review and calculate tax
The portal calculates your total tax liability, compares it with TDS already deducted, and shows either 'Tax Due' (you owe more) or 'Refund' (excess TDS — money comes back to you). If tax is due, pay via Challan 280 (net banking or UPI) before submitting.
7
Submit and e-Verify
Submit the ITR. Then e-Verify immediately — this is MANDATORY. Options: Aadhaar OTP (simplest — 6-digit OTP on Aadhaar-linked mobile), Net Banking, DSC, or send signed ITR-V to Bangalore CPC by post within 30 days. Without verification, your ITR is considered NOT FILED.

⚖️Old Regime vs New Regime — Which Saves More Tax?

The New Tax Regime (default from FY 2023-24) has lower tax rates: 0% up to ₹3L, 5% for ₹3-7L, 10% for ₹7-10L, 15% for ₹10-12L, 20% for ₹12-15L, 30% above ₹15L. Plus standard deduction of ₹75,000.

The Old Tax Regime has higher rates (5% above ₹3L, 20% above ₹5L, 30% above ₹10L) but allows ALL deductions: 80C (₹1.5L), 80D, HRA, LTA, 80CCD(1B) NPS, home loan interest, etc.

Quick rule of thumb: If your total deductions (80C + 80D + HRA + others) exceed approximately ₹3.75 lakh, the Old Regime likely saves more tax. If deductions are less, the New Regime is better. The e-filing portal has a 'Compare' feature — use it before choosing.

You can switch between regimes every year (for salaried employees). For self-employed/business income, switching is allowed only once in a lifetime. Choose carefully for business income.

⚠️Common Mistakes That Cost You Money

Mistake 1: Not filing ITR because 'no tax is due'. Even with zero tax liability, file ITR — it serves as income proof for home loans, car loans, visa applications, and credit card approvals. Banks ask for last 2-3 years' ITR. No ITR = difficulty getting loans.

Mistake 2: Not reporting bank interest and FD interest. The income tax department automatically gets this data from banks. If you don't report it in your ITR but they have it in their records, you'll get a notice under Section 143(1) with demand for tax + interest. Always check your AIS (Annual Information Statement) for all income sources.

Mistake 3: Missing the e-Verification step. Submitting ITR is not enough — you MUST e-verify it within 30 days. Many people submit and forget. An unverified ITR is treated as if you never filed. E-verify immediately using Aadhaar OTP — takes 30 seconds.

Mistake 4: Not claiming all eligible deductions. Common missed deductions: Section 80D (health insurance premium for self + parents), Section 80TTA (₹10,000 savings interest deduction), NPS employer contribution (even in New Regime), education loan interest (Section 80E — no upper limit). Check all sections before submitting.

Mistake 5: Filing the wrong ITR form. ITR-1 is only for salaried with income ≤₹50L and one house. If you have capital gains (from stocks, mutual funds, property sale), you need ITR-2. If you have business income, you need ITR-3/4. Wrong form = notice from IT department.
