Income Tax Return Filing: A Complete Step-by-Step Guide for FY 2025-26

Why Filing ITR on Time Matters

Filing Income Tax Returns (ITR) is not just a legal obligation for those whose income exceeds the taxable threshold — it's a financial habit that creates documented proof of income for loans, visas, and financial credibility.

The due date for ITR filing for most individuals is July 31, 2026 (for FY 2025-26, AY 2026-27). Late filing attracts penalties up to ₹5,000 and interest on unpaid tax. Even if you have no tax payable, filing a NIL return maintains your compliance record.

Which ITR Form Should You Use?

• ITR-1 (Sahaj): For individuals with income from salary, one house property, and other sources (interest, dividends). Total income up to ₹50 lakhs. Not for LLP or foreign income.
• ITR-2: For individuals and HUFs with income from capital gains, foreign assets, or more than one house property.
• ITR-3: For individuals and HUFs with income from business or profession.
• ITR-4 (Sugam): For individuals, HUFs, and firms (not LLP) with presumptive income from business or profession.

Documents You Need

• Form 16: From employer (TDS certificate showing income, deductions, TDS)
• PAN card and Aadhaar card
• Bank statements: For interest income from savings accounts, fixed deposits
• Home loan statement: For interest deduction under Section 24 (if applicable)
• Investment proofs: For Section 80C (life insurance, ELSS, PPF, EPF, housing loan principal), 80D (health insurance), 80CCD(1B) (NPS)
• Capital gains statements: From broker or bank for equity/stock gains
• Rental income details: If you have rental income

Step-by-Step: Filing ITR on the Income Tax Portal

Step 1: Gather Form 16 and Investment Proofs

Form 16 has Part A (TDS details) and Part B (income breakdown). Verify your PAN matches on Form 16. Collect all 80C, 80D, and other investment proofs from banks, insurers, and employers.

Step 2: Login to Income Tax Portal

Go to https://www.incometax.gov.in and login with your PAN as user ID. Register if first-time user. Enable Aadhaar-linked OTP for login or use digital signature.

Step 3: Select the Correct ITR Form

The portal will suggest the appropriate ITR form based on your income type. Choose the lowest-numbered form that applies to your situation.

Step 4: Fill in Personal Details

Verify pre-filled data (PAN, Aadhaar, name, address, bank account details). Update if needed. Choose your filing status (individual/HUF) and occupation code.

Step 5: Enter Income Details

Income from salary is pre-filled from Form 16. Add income from other sources (interest, dividends, rental). Add capital gains if applicable. Add income from house property if you have a home loan or rental property.

Step 6: Claim Deductions

Under Chapter VI-A deductions:

• 80C: Life insurance, ELSS, PPF, EPF, housing loan principal, children's tuition fees (max ₹1.5 lakhs)
• 80CCD(1): NPS contribution (max ₹1.5 lakhs)
• 80CCD(1B): Additional NPS deduction (max ₹50,000)
• 80D: Health insurance premium (₹25,000-100,000 depending on age and coverage)
• 80E: Education loan interest (no cap)
• 80G: Donations to approved charities (50-100% deduction)
• 80TTA: Savings account interest (up to ₹10,000)

Step 7: Verify Tax Payable/Refund

The portal calculates tax based on your income and deductions. If tax paid (TDS + advance tax) exceeds tax liability, you get a refund. If less, you must pay the balance before filing (or claim it as tax credit carry-forward).

Step 8: Preview and Submit

Download Form 26AS to verify TDS entries match your Form 16. Preview ITR JSON. Submit with OTP/Aadhaar-linked e-verification. File within due date to avoid late fees.

Form 26AS: Your TDS History

Form 26AS is a consolidated tax statement showing all TDS and advance tax paid against your PAN. Always verify your Form 26AS before filing — if TDS in Form 26AS doesn't match your Form 16, claim only what's in 26AS and follow up with the deductor for correction.

Frequently Asked Questions

Do I need to file ITR if my income is below the taxable threshold?

Not legally required if income is below ₹3 lakhs (new tax regime) or ₹2.5 lakhs (old tax regime). However, filing even NIL returns is advisable if you want to: apply for visas (most embassies ask for 3 years of ITR), get large loans (banks ask for ITR of 1-3 years), carry forward losses to future years, or maintain financial documentation for any purpose.

What is the penalty for late ITR filing?

Late filing fee (Section 234F): ₹1,000 if total income up to ₹5 lakhs; ₹5,000 if above ₹5 lakhs. Additionally, interest under Section 234A is charged at 1% per month on unpaid tax from the due date until filing. After December 31, 2026, prosecution proceedings may also be initiated for persistent non-filing.

Can I claim HRA if I live in my own house with a home loan?

No. You cannot claim HRA (House Rent Allowance) if you own a house in the same city where you work. However, if you have a home loan on a property that is not in the same city as your workplace, you can claim Section 24(b) deduction for interest paid (up to ₹2 lakhs per year) while claiming HRA for rented accommodation elsewhere. Owning a house in a different city doesn't affect HRA eligibility.

Don't Wait Until July 30

ITR filing doesn't have to be stressful. Collect your documents in April-May, file by June if possible — avoid the July rush and last-minute technical glitches on the IT portal. If your income is complex (capital gains, business income, multiple properties), consider a chartered accountant. The penalty for late filing is never worth the procrastination.
