Filing your Income Tax Return (ITR) is a statutory obligation for every eligible taxpayer in India. The Income Tax Department has significantly improved the e-filing portal to make the process smoother, faster, and more intuitive. Here's your definitive guide for FY 2024-25 (AY 2025-26).

"Timely and accurate ITR filing not only ensures compliance but also builds your financial credibility for future loans and visa applications."

Step 1: Gather All Required Documents

Before starting the filing process, organise all relevant documents to avoid errors and rework:

  • Form 16 – Issued by your employer; contains salary and TDS details
  • Form 26AS – Tax credit statement; download from incometax.gov.in
  • AIS & TIS – Annual Information Statement and Taxpayer Information Summary
  • Bank statements and interest certificates (FD, savings account)
  • Investment proofs (80C – LIC, PPF, ELSS; 80D – health insurance; HRA; LTA)
  • Capital gain statements from broker or mutual fund houses
Pro Tip: Always cross-check your Form 26AS with your Form 16. Any mismatch in TDS figures could trigger a notice from the Income Tax Department.

Step 2: Choose the Right ITR Form

India offers 7 different ITR forms based on income sources and category. Selecting the wrong form can make your return "defective".

ITR-1 (Sahaj)
For salaried individuals with income up to ₹50 lakhs, one house property, and no capital gains.
ITR-2
For those with capital gains, foreign income, multiple properties, or income above ₹50 lakhs.
ITR-3
For professionals and business owners with income from business or profession.
ITR-4 (Sugam)
For those opting for presumptive taxation under sections 44AD, 44ADA, or 44AE.

Step 3: Old Regime vs New Regime

FY 2024-25 introduces significant changes. Under Budget 2024, the standard deduction for salaried employees under the new regime increased to ₹75,000. This changes the calculus for many taxpayers.

Income Slab Old Regime Rate New Regime Rate
Up to ₹3,00,000NilNil
₹3L – ₹7L5%5%
₹7L – ₹10L20%10%
₹10L – ₹12L30%15%
₹12L – ₹15L30%20%
Above ₹15L30%30%
Key Decision: If your total deductions (80C + 80D + HRA + LTA etc.) exceed ₹1.75–2 lakhs, the old regime is likely more beneficial. Otherwise, consider the new regime for its lower slab rates.

Step 4: E-File on the Income Tax Portal

  1. Login to incometax.gov.in using your PAN and password
  2. Navigate to e-File → Income Tax Returns → File Income Tax Return
  3. Select the Assessment Year (AY 2025-26) and filing mode as Online
  4. Choose the correct ITR form based on your income profile
  5. Review the pre-filled data from AIS — correct any discrepancies
  6. Enter remaining income and deduction details manually
  7. Compute tax liability and pay any Self Assessment Tax via Challan 280
  8. Submit and e-Verify within 30 days using Aadhaar OTP, Net Banking, or DSC
