Filing your Income Tax Return (ITR) for Financial Year 2025-26 (Assessment Year 2026-27) is now entirely digital and more streamlined than ever. With the Income Tax Department's enhanced e-filing portal and pre-filled forms, the process has become significantly easier for taxpayers across India. This comprehensive guide walks you through every step of filing your ITR online.
Understanding ITR Filing for FY 2025-26
The Financial Year 2025-26 runs from 1st April 2025 to 31st March 2026, and the corresponding Assessment Year is 2026-27. All income earned during FY 2025-26 must be reported in your ITR filed during AY 2026-27. As of April 2026, taxpayers can begin filing their returns for the previous financial year.
The Income Tax Department has introduced several improvements to the e-filing system, including enhanced pre-filling of data, faster processing, and improved user interface. Understanding these changes is crucial for smooth filing.
Important Dates and Deadlines
For FY 2025-26 (AY 2026-27), the key deadlines are:
- 31st July 2026: Due date for individuals, HUFs, and non-audit cases
- 31st October 2026: Due date for tax audit cases
- 31st December 2026: Due date for updated returns (if applicable)
- 31st March 2027: Last date for belated/revised returns
Filing after the due date attracts penalties under Section 234F, ranging from ₹1,000 to ₹5,000, depending on your total income.
Choosing the Right ITR Form
Selecting the correct ITR form is critical. Here's a breakdown:

ITR-2

ITR-4 (Sugam)

Gather these essential documents before starting your ITR filing:
- PAN Card: Your permanent account number
- Aadhaar Card: Mandatory for e-verification
- Form 16: TDS certificate from employer(s)
- Form 16A/16B/16C: TDS certificates for other income
- Form 26AS: Annual tax statement showing all TDS
- AIS/TIS: Annual Information Statement and Taxpayer Information Summary
- Salary Slips: Monthly salary breakup

- Previous Year ITR: For reference and carry-forward losses
Step-by-Step ITR Filing Process
Step 1: Register/Login to E-Filing Portal
Visit the official Income Tax e-filing portal at www.incometax.gov.in. If you're a first-time user, register using your PAN and complete the OTP verification. Existing users can directly log in using their credentials.
Step 2: Download Pre-Filled Data
After logging in, navigate to the 'e-File' menu and select 'Income Tax Return'. Choose AY 2026-27 and click on 'Continue'. The system will display various pre-filled information sources:
- Form 26AS (TDS details)
- Annual Information Statement (AIS)
- Form 16 uploaded by employer
- Interest certificates from banks
- Capital gains from stock exchanges
Download and verify this data carefully. The pre-filled information significantly reduces manual data entry.
Step 3: Select Your ITR Form
Based on your income sources, select the appropriate ITR form. The portal provides a smart selection tool that recommends the correct form based on your income profile. You can file either online (through the portal) or offline (by uploading JSON/XML file).
Step 4: Choose Filing Mode
Select between online and offline filing:
Online Filing: Fill the form directly on the portal. This method is recommended for simpler returns (ITR-1, ITR-4) as it's more user-friendly with validations at each step.
Offline Filing: Download the JSON utility, fill it offline, generate XML, and upload. Suitable for complex returns with multiple income sources.
Step 5: Fill Personal Information
Enter or verify your personal details:
- Name, PAN, Aadhaar number
- Date of birth and gender
- Residential status
- Contact details (mobile and email)
- Address details
- Bank account details for refund
Most of this information will be pre-filled from your PAN and previous year's return.
Step 6: Report Income Details
Fill in all income details under appropriate heads:
Salary Income: Enter gross salary, allowances, perquisites, and deductions. Use Form 16 provided by your employer. If you have multiple employers, add each separately.
House Property Income: Report rental income or losses. For self-occupied property, claim interest deduction under Section 24(b). Calculate deemed rental income for vacant properties if applicable.
Capital Gains: Report short-term and long-term capital gains from sale of assets like shares, mutual funds, property, or gold. Use statements from brokers and depository participants.
Business/Professional Income: Enter net profit after allowed deductions. Attach profit and loss account and balance sheet if required.
Other Sources: Include interest income from savings accounts, fixed deposits, recurring deposits, and any other income not covered under previous heads.
Step 7: Claim Deductions
Maximize your tax savings by claiming eligible deductions:
Section 80C: Up to ₹1.5 lakh for investments in PPF, ELSS, life insurance premiums, EPF, home loan principal repayment, tuition fees, etc.
Section 80D: Health insurance premiums up to ₹25,000 for self/family and ₹50,000 for parents (₹1 lakh if parents are senior citizens).
Section 80E: Interest on education loans without any upper limit.
Section 80G: Donations to eligible charitable institutions.
Section 24(b): Home loan interest up to ₹2 lakh for self-occupied property.
Standard Deduction: ₹50,000 for salaried individuals (verify current limit).
Under the new tax regime applicable from FY 2023-24 onwards, most deductions are not available. Choose your tax regime carefully after calculating tax under both regimes.
Step 8: Calculate Tax Liability
The system automatically calculates your total income, deductions, taxable income, and tax liability. It also factors in:
- Tax already paid through TDS/TCS
- Self-assessment tax paid
- Advance tax paid
- Relief under Section 89 (if applicable)
The final result shows whether you have a tax liability or refund due.
Step 9: Pay Tax (If Applicable)
If you have additional tax liability, pay it before filing. Use Challan 280 to pay tax online through the portal. The payment options include:
- Net banking
- Debit card
- NEFT/RTGS
After payment, note the BSR code, challan number, and date for entering in your ITR.
Step 10: Validate and Submit
Before submission, carefully review all entered information. The portal performs validations and highlights errors or missing information. Common validation checks include:
- Matching TDS with Form 26AS
- Correct bank account details (IFSC, account number)
- Sum totals of various income heads
- Proper disclosure of exempt income
Once satisfied, submit your ITR. The system generates an acknowledgement number. Save and download the acknowledgement (ITR-V) for your records.
Step 11: E-Verify Your Return
This is the most crucial step. Your ITR filing is incomplete without verification. You must verify within 30 days of filing through any of these methods:
Aadhaar OTP: Instant verification using OTP sent to your Aadhaar-linked mobile number (most convenient method).
Net Banking: Login through your pre-validated bank account and verify electronically.
Bank Account Validation: Verify through your bank account using an EVC (Electronic Verification Code).
Demat Account: Use your demat account for verification.
Bank ATM: Generate EVC from your bank ATM and use it for verification.
Digital Signature Certificate (DSC): For those having a valid DSC.
If you cannot e-verify, send a signed physical copy of ITR-V to CPC Bangalore within 30 days by ordinary/speed post.
Post-Filing Steps
After successful e-verification:
- Confirmation Email: You'll receive acknowledgement that your ITR has been filed and verified successfully
- Processing: The Income Tax Department processes your return, typically within 30-45 days
- Intimation u/s 143(1): You receive an intimation accepting your return or highlighting discrepancies
- Refund Processing: If eligible, refund is credited to your bank account within 45-60 days
- Track Status: Monitor your refund status through the e-filing portal or NSDL website
Common Mistakes to Avoid
- Choosing the wrong ITR form
- Not verifying Form 26AS and AIS before filing
- Incorrect bank account details (IFSC code errors)
- Not claiming all eligible deductions
- Forgetting to report exempt income
- Not carrying forward losses properly
- Missing the e-verification deadline
- Not maintaining supporting documents
- Ignoring discrepancies highlighted in AIS
Tips for Smooth ITR Filing
Start Early: Don't wait until the deadline. File early to avoid last-minute server issues and technical glitches.
Check AIS Thoroughly: The Annual Information Statement contains all financial transactions. Verify each entry and report discrepancies.
Keep Documents Organized: Maintain all supporting documents for at least 6 years as required by law.
Choose Tax Regime Wisely: Calculate tax under both old and new regimes to determine which is more beneficial.
Report All Income: Even small income like interest from savings accounts should be reported to avoid notices.
Double-Check Bank Details: Incorrect bank details delay refunds significantly.
Revised Returns
If you discover errors after filing, you can file a revised return under Section 139(5) before the end of the assessment year or completion of assessment, whichever is earlier. For AY 2026-27, this deadline is 31st March 2027.
Common reasons for revision include:
- Income omitted inadvertently
- Wrong claim of deductions
- Incorrect tax calculation
- Selection of wrong ITR form
Conclusion
Filing ITR online for FY 2025-26 has become increasingly user-friendly with technological improvements and pre-filled data. By following this step-by-step guide, organizing your documents, and starting early, you can complete your tax filing smoothly. Remember that timely and accurate ITR filing not only fulfills your legal obligation but also helps in loan applications, visa processing, and maintaining a clean financial record.
If your case involves complex transactions, foreign assets, or business income requiring detailed reporting, consider consulting a chartered accountant or tax professional. However, for most salaried individuals and straightforward income scenarios, self-filing through the e-filing portal is simple and convenient.
Stay updated with the latest notifications from the Income Tax Department, as rules and procedures may change. Always verify information from official government sources before filing your return.
