Every Indian resident whose gross total income exceeds ₹3 lakh under the new tax regime or ₹2.5 lakh under the old tax regime must file an Income Tax Return (ITR) with the Income Tax Department before July 31, 2026 for the financial year 2025-26 (Assessment Year 2026-27). An Income Tax Return is a prescribed form in which a taxpayer declares their total income, applicable deductions, exemptions, and tax liability for a given financial year. Filing ITR is not just a legal obligation — it serves as proof of income for visa applications, loan approvals, and government tenders. Even if your income falls below the taxable threshold, filing a return can help you claim TDS refunds, carry forward losses, and build a documented financial history.
The Income Tax Department has made the entire filing process digital through the e-filing portal at incometax.gov.in. Whether you are a salaried employee, freelancer, business owner, or investor, this guide walks you through every step of filing your ITR online for FY 2025-26 — from gathering documents to e-verification.
Key Takeaways
- Deadline: July 31, 2026 is the last date to file ITR for FY 2025-26 (AY 2026-27) without penalty for individuals and HUFs not subject to audit.
- Choose the right form: Most salaried individuals with income up to ₹50 lakh use ITR-1 (Sahaj). Business owners and professionals use ITR-3 or ITR-4.
- Documents needed: Form 16, Form 26AS, Annual Information Statement (AIS), bank statements, investment proofs under Section 80C/80D, and capital gains statements.
- New regime is default: The new tax regime (with no deductions but lower slab rates) is the default from FY 2023-24 onwards. You must explicitly opt out to use the old regime.
- e-Verification is mandatory: Your return is not treated as filed until you e-verify it within 30 days of submission using Aadhaar OTP, net banking, or Digital Signature Certificate (DSC).
- Penalty for late filing: ₹5,000 if filed after July 31 but before December 31, 2026. ₹10,000 if filed after December 31. Reduced to ₹1,000 if total income is below ₹5 lakh.

Step-by-Step: How to File ITR Online for FY 2025-26

Step 1: Log In to the e-Filing Portal
Visit incometax.gov.in and click "Login." Enter your PAN number as User ID, password, and OTP sent to your registered mobile. First-time filers: click "Register" to create an account using PAN, Aadhaar, and mobile number.
Navigate to e-File → Income Tax Returns → File Income Tax Return.
Step 2: Select Assessment Year (AY 2026-27)
Select Assessment Year 2026-27. The assessment year is always one year ahead of the financial year. Choose Online filing mode (recommended) or Offline (JSON utility).
Step 3: Choose Your ITR Form
The portal may suggest a form based on pre-filled data. Verify against the ITR form table above. Wrong form selection leads to a defective return notice under Section 139(9).
Step 4: Select Filing Type
- Original (Section 139(1)) — first-time filing for this AY.
- Revised (Section 139(5)) — correcting a previously filed return.
- Belated (Section 139(4)) — filing after July 31 but before December 31.
Step 5: Choose Your Tax Regime (Old vs New)
The new tax regime is the default from FY 2023-24. To use the old regime (allowing 80C, 80D, HRA deductions), file Form 10-IEA before filing your return.
| Income Slab | Old Regime Rate | New Regime Rate |
|---|---|---|
| Up to ₹2.5L (Old) / ₹3L (New) | Nil | Nil |
| ₹2.5-5L (Old) / ₹3-7L (New) | 5% | 5% |
| ₹5-10L (Old) / ₹7-10L (New) | 20% | 10% |
| ₹10-12L (New) | 30% | 15% |
| ₹12-15L (New) | 30% | 20% |
| Above ₹15L (New) / Above ₹10L (Old) | 30% | 30% |
Use our Income Tax Calculator to compare both regimes. Read: Old vs New Tax Regime — Which Is Better?
Step 6: Pre-fill Data from Form 26AS and AIS
Click "Pre-fill". The portal fetches income data automatically. Do not blindly accept pre-filled data. Cross-check every entry. Common mismatches: FD interest amounts, MF capital gains showing redemption instead of gains, missing dividend entries.
Step 7: Verify and Enter Income Details
Salary: Verify gross salary, HRA, standard deduction (₹75,000 new / ₹50,000 old), professional tax. Match with Form 16.
House Property: Self-occupied = nil value, claim home loan interest under Section 24(b). Let-out = annual rent minus municipal taxes minus 30% standard deduction.
Capital Gains:
STCG on equity at 20%, LTCG on equity at 12.5% (above ₹1.25 lakh exemption). Import broker statements for accuracy.
Other Sources: Savings interest, FD interest, dividends, gifts above ₹50,000.
Step 8: Enter Deductions (Old Regime Only)
Key deductions: Section 80C (₹1.5 lakh), 80CCD(1B) (₹50,000 NPS), 80D (₹25K-₹1 lakh health insurance), Section 24(b) (₹2 lakh home loan interest), 80E (education loan interest), 80G (donations). See our complete 80C guide and salary tax saving guide.
Step 9: Calculate Tax, Review, and Submit
Click "Calculate Tax". The portal shows: no tax due, tax payable (pay via Challan 280), or refund due (ensure bank is pre-validated). Review every schedule before submitting.
Step 10: e-Verify Your Return
Your ITR is not valid until e-verified within 30 days. Three methods:
- Aadhaar OTP (recommended) — fastest, takes under 2 minutes.
- Net Banking — through pre-validated banks (SBI, ICICI, HDFC).
- Digital Signature Certificate (DSC) — for companies and professionals.
After verification, save the ITR-V acknowledgment — it is your proof of filing.

|---|---|---|
| Gross Salary | ₹12,00,000 | ₹12,00,000 |

| HRA Exemption | Not allowed | ₹1,80,000 |
| 80C + 80D + NPS | Not allowed | ₹2,50,000 |
| Net Taxable Income | ₹11,25,000 | ₹7,20,000 |
| Total Tax | ₹74,100 | ₹46,176 |
Verdict: With substantial deductions, old regime saves ₹28,000 at ₹12 lakh salary.
Example 3: ₹20 Lakh with Capital Gains + Rental Income
| Income Source | Amount |
|---|---|
| Salary (gross) | ₹15,00,000 |
| Rental Income | ₹3,60,000 |
| STCG (equity) | ₹80,000 |
| LTCG (equity, above exemption) | ₹60,000 |
| Total Tax (New Regime) | ₹2,04,464 |
Capital gains are taxed at special rates regardless of regime. This taxpayer must file ITR-2.
Common Mistakes to Avoid
1. Not Reconciling Form 26AS/AIS
The department auto-checks declared income against 26AS/AIS. Mismatches trigger notices. Always reconcile before filing.
2. Forgetting Bank Interest and FD Income
Interest from all accounts is taxable and tracked via AIS. Not declaring it is the fastest way to get a notice.
3. Choosing the Wrong ITR Form
Sold mutual funds but filed ITR-1? That's a defective return. Verify form eligibility first.
4. Not e-Verifying Within 30 Days
Without e-verification, your return is treated as never filed. Verify immediately with Aadhaar OTP.
5. Ignoring Capital Gains from MF Redemptions
Every redemption, SWP, and switch is taxable. Download consolidated statement from CAMS/KFintech.
6. Not Claiming TDS Refund
If TDS exceeds actual tax liability, file ITR to claim the refund. Many leave lakhs unclaimed.
7. Filing After Deadline Without Understanding Penalties
Late filing = no loss carry forward + penalties + higher future TDS. Pay self-assessed tax by July 31 at minimum.
Penalties for Late Filing
| Total Income | After July 31 (before Dec 31) | After December 31 |
|---|---|---|
| Up to ₹5 lakh | ₹1,000 | ₹1,000 |
| Above ₹5 lakh | ₹5,000 | ₹10,000 |
Additional: 1% interest per month on outstanding tax (Section 234A), loss of carry forward rights, higher future TDS under Section 206AB.
When to File a Revised Return
Mistakes in your original ITR? File a revised return under Section 139(5) before December 31, 2026. No penalty for revision. Reasons: missed income, wrong deduction, wrong form, regime switch (salary-only taxpayers), or revised Form 16 from employer.
Frequently Asked Questions
What is the last date to file ITR for FY 2025-26?
July 31, 2026 for individuals and HUFs not requiring audit. October 31, 2026 for businesses requiring audit. November 30, 2026 for transfer pricing cases.
Can I file ITR without Form 16?
Yes. Use salary slips and download Form 26AS + AIS from the e-filing portal to verify TDS details. Form 16 is a TDS certificate — the data is already in 26AS.
Which regime should I choose — old or new?
New regime if total deductions are below ~₹3.75 lakh. Old regime if deductions exceed that. Use our Tax Calculator to compare exact numbers for your salary.
Do I need a CA to file ITR?
Not for most salaried individuals. The portal's guided process handles ITR-1 and ITR-2 well. Consider a CA for complex business income, foreign assets, or department notices. Fees: ₹1,000-₹3,000 for salary returns.
What is e-verification and how to do it?
Digital signature for your return. Fastest method: Aadhaar OTP — enter OTP sent to Aadhaar-linked mobile. Alternatives: net banking or DSC. Must complete within 30 days of filing.
Can I switch regime after filing?
Salary-only taxpayers: yes, by filing revised return before December 31. Business income: more restrictive — one-time switch from new to old requires Form 10-IEA before July 31 due date.
What if I have income from multiple sources?
Use the correct ITR form: salary + capital gains = ITR-2, salary + business = ITR-3. Report all sources — the department cross-references AIS data across all PANs and bank accounts.
Is ITR filing mandatory if income is below taxable limit?
Not legally mandatory (unless mandatory filing conditions apply). But strongly recommended for TDS refunds, loss carry forward, loan applications, and visa documentation.
How to claim TDS refund?
File ITR with correct income. If TDS (from 26AS) exceeds your tax liability, the excess is auto-refunded to your pre-validated bank account within 30-60 days with interest under Section 244A.
What happens if I don't file ITR?
Penalty up to ₹10,000, loss of carry forward rights, double TDS on future income under Section 206AB, risk of prosecution for tax dues above ₹10,000, and best judgment assessment under Section 144.
