Step-by-Step Guide to File ITR Online
Step 1: Register or Log In to the Income Tax Portal
Visit the official Income Tax e-filing portal at incometax.gov.in. If you are a first-time user, register using your PAN number. Existing users can log in with their credentials. After logging in, you will see your dashboard with options for filing returns, viewing past returns, and checking refund status.
Step 2: Select the Assessment Year
Click on “e-File” > “Income Tax Returns” > “File Income Tax Return”. Select the correct assessment year — for income earned in FY 2025-26, select AY 2026-27. Choose whether you want to file online or upload an offline JSON file.
Step 3: Choose the Right ITR Form
The portal helps you select the correct form based on your income sources:
- ITR-1 (Sahaj) — For salaried individuals with income up to Rs 50 lakh from salary, one house property, and other sources.
- ITR-2 — For individuals with capital gains or multiple house properties.
- ITR-3 — For individuals with business or professional income.
- ITR-4 (Sugam) — For those opting for presumptive taxation under Sections 44AD, 44ADA, or 44AE.
Step 4: Fill in Your Income Details
The portal pre-fills much of your data from Form 26AS, AIS, and TIS. Verify all pre-filled information including salary income, TDS details, and bank interest. Add any additional income sources that are not pre-filled, such as freelance income, rental income, or capital gains.
Step 5: Claim Deductions
Under the deductions section, claim all eligible deductions. The most common ones include Section 80C (up to Rs 1.5 lakh for investments like PPF, ELSS, life insurance), Section 80D (health insurance premiums), Section 80TTA (savings account interest up to Rs 10,000), and Section 24(b) for home loan interest.
Step 6: Calculate and Pay Tax
The portal automatically calculates your total tax liability after deductions. If there is any outstanding tax, pay it through the “Pay Tax” option using net banking, debit card, or UPI. Keep the challan receipt handy.
Step 7: Verify and Submit
Review all the details carefully. Once satisfied, submit your return. You must verify your ITR within 30 days of filing. The easiest method is e-Verification using Aadhaar OTP. Other options include net banking, bank account EVC, or sending a signed ITR-V to CPC Bengaluru.
Common Mistakes to Avoid
Many taxpayers make avoidable errors that can lead to notices or delayed refunds. Do not forget to report all income sources including bank interest and capital gains. Ensure your bank account details are correct for receiving refunds. Always verify your return after filing. Cross-check Form 26AS to ensure all TDS credits are reflected correctly.
Due Date for Filing ITR
The due date for filing ITR for individuals for FY 2025-26 is 31st July 2026. Filing after the due date attracts a late fee of Rs 1,000 to Rs 5,000 and you may lose the ability to carry forward certain losses.
