Why You Should File Your ITR Even If Tax Is Zero
Filing an ITR is not just a legal obligation — it is a financial instrument that proves your income and tax compliance history. Many salaried individuals earning below Rs 12.75 lakh under the new regime have zero tax liability but still have compelling reasons to file their ITR before July 31, 2025.
Home loan applications require the last 2–3 years of ITR to assess income stability. Visa applications for countries like the US, UK, Schengen zone, and Canada routinely ask for proof of income tax filing. If you want to carry forward capital losses (from share trading or property sales) to offset future gains, you must file the ITR by the due date. Refund claims for excess TDS deducted can only be processed through an ITR.
The income tax portal now enables pre-filled ITR with data from Form 26AS, AIS, and employer-reported information (Form 16). The pre-filling covers salary, TDS, bank interest, dividends from demat accounts, and mutual fund transactions. For most salaried individuals with straightforward income, filing the ITR takes less than 30 minutes using the pre-filled data and Aadhaar OTP verification.
Which ITR Form Should You Use for AY 2025-26?
Selecting the wrong ITR form is a defective return. The income tax portal will allow submission but may later issue a defective notice requiring re-filing with the correct form. Here are the four main forms used by individuals:

Step-by-Step: How to File ITR Online on incometax.gov.in
The income tax portal at incometax.gov.in is the official platform for filing ITR. These steps apply to ITR-1 and ITR-2 filing for salaried individuals:
Login to the Income Tax Portal
Visit incometax.gov.in and log in using your PAN as user ID and your registered password. If you haven't registered, click 'Register' and complete the process using your PAN, Aadhaar, and email. Your PAN is your permanent identifier across all income tax transactions.
Review AIS and Form 26AS Before Starting
Before beginning your ITR, review your Annual Information Statement (AIS) and Form 26AS. Go to 'e-File > Income Tax Return > View AIS' and 'e-File > View Form 26AS'. Check that all income credited to your PAN (salary, interest, dividends, capital gains) is accurately reflected. If there are discrepancies, flag them in the AIS feedback section before filing.
Start New ITR Filing
Go to 'e-File > Income Tax Returns > File Income Tax Return'. Select Assessment Year 2025-26. Select 'Online' mode for the simplified online form. Select the applicable filing status (Individual / HUF). Confirm that you are not filing a revised or defective return if this is your first submission for AY 2025-26.
Select the Correct ITR Form
The portal will ask a series of questions to help determine the correct ITR form. Answer accurately: do you have capital gains? Foreign income? Business income? More than one house property? Based on your responses, it will recommend ITR-1 or ITR-2. You can also directly select your form if you already know which one applies.
Select Tax Regime
Indicate whether you are filing under the new tax regime (default) or the old tax regime. If choosing old regime, ensure you have filed Form 10-IEA separately. The portal will apply the correct slabs and allow applicable deductions based on your regime selection. For new regime, most deduction sections will be greyed out.
Validate Pre-Filled Data
The portal will pre-fill salary income (from Form 16 employer data), TDS (from Form 26AS), interest income (from bank data), and dividend income (from demat records). Review each pre-filled figure carefully. If any figure is wrong or missing — for example, employer has not filed TDS return correctly — enter the correct figures manually and note the discrepancy.
Enter Deductions (Old Regime Taxpayers)
If filing under old regime, enter all Chapter VI-A deductions: 80C (specify investment amounts), 80D (health insurance premiums), 80CCD(1B) (NPS amount), 80E (education loan interest), 80G (donations), and any other applicable sections. Supporting documents are not uploaded — they must be kept for 7 years as the income tax department may ask for them during scrutiny.
Compute Tax and Review Summary
The portal computes tax based on your entries. Review the tax computation summary: gross income, total deductions, net taxable income, slab-wise tax, Section 87A rebate (if eligible), surcharge, cess, TDS credit from Form 26AS, and net tax payable or refund due. Verify that TDS credit matches your Form 16 and Form 26AS exactly.
Pay Any Balance Tax Due (Self-Assessment Tax)
If you have additional tax to pay (i.e., tax liability exceeds TDS already deducted), pay it before submitting the ITR. Under 'e-Pay Tax', choose 'Income Tax' and 'Self-Assessment Tax (300)'. Pay via net banking or UPI. Note the BSR code and challan serial number and enter it in the ITR before filing. Submitting without paying balance tax can result in a demand notice.
Submit and E-Verify
Once all data is entered and reviewed, click 'Submit'. This files your ITR but it is NOT processed until e-verified. Immediately proceed to e-verify using Aadhaar OTP (recommended — fastest), net banking, or bank account EVC. E-verification must be completed within 30 days. After successful e-verification, you receive an acknowledgement number. Processing typically takes 15–45 days.
ITR E-Verification Methods — Which Is Fastest?
E-verification is the final step in ITR filing. An unverified ITR is treated as not filed. Verify within 30 days of submission to avoid late filing penalties.
| Method | Time | Requirement | Recommended? |
|---|---|---|---|
| Aadhaar OTP | Instant | Aadhaar linked to current mobile number | Yes |
| Net Banking EVC | Instant | Net banking with major banks (SBI, HDFC, ICICI, etc.) linked to PAN | Yes |
| Bank Account EVC | Instant after pre-validation | Bank account pre-validated on income tax portal | Alternate |
| Demat Account EVC | Instant after pre-validation | Demat account pre-validated on income tax portal | Alternate |
| Digital Signature Certificate (DSC) | Instant | Valid DSC registered on income tax portal — required for some audit cases | Alternate |
| Physical ITR-V (by post) | 15–20 days | Print, sign, and speed-post to CPC Bengaluru — not recommended | Alternate |
Late Filing: Penalties and Consequences After July 31, 2025
Late Fee Under Section 234F
After December 31, 2025, you cannot file a voluntary ITR for AY 2025-26 unless the income tax department opens a window for updated returns under Section 139(8A).
Other Consequences of Late Filing
- Interest under Section 234A: 1% per month on unpaid tax from July 31
- Losses from capital gains, business, or speculation cannot be carried forward
- House property losses can still be carried forward even in belated return
- No revised return possible after December 31 deadline
- Possible scrutiny selection for habitual late filers
- Refund processing is delayed significantly for belated returns
- Loan applications and visa processing may be affected by absence of on-time ITR
Benefits of Filing ITR on Time (Before July 31, 2025)
Home Loan Applications
Banks require ITR for 2–3 years to assess income stability. On-time filing creates a consistent filing history that strengthens your loan application.
Visa Processing
Most embassy applications (US B-1/B-2, UK, Schengen, Canada) require proof of income tax filing. ITR acknowledgement is the most accepted document.
Carry Forward Capital Losses
If you incurred losses in stock trading or from property sales, they can only be carried forward to offset future gains if ITR is filed by July 31. Late filing forfeits this right.
Faster Refund Processing
On-time filers get priority in refund processing. Refunds from excess TDS are typically processed within 15–45 days after e-verification for timely returns.
Revised Return Option
Filing on time gives you the ability to file a revised return up to December 31 if you discover an error. Late filers lose this additional correction window.
High-Value Transaction Disclosure
Banks, mutual funds, and other institutions report large transactions to the income tax department via AIS. Filing on time with accurate disclosure prevents notices under Section 148 or 148A.
Frequently Asked Questions
What is the ITR filing deadline for AY 2025-26?
July 31, 2025 for salaried individuals and HUFs not requiring tax audit. October 31, 2025 for audit cases. Belated return can be filed up to December 31, 2025 with a late fee of Rs 1,000 (income below Rs 5L) or Rs 5,000 (income above Rs 5L).
Which ITR form should a salaried person use?
ITR-1 (Sahaj) for salary income up to Rs 50 lakh with no capital gains. ITR-2 for salary with capital gains, multiple house properties, foreign assets, or income above Rs 50 lakh. ITR-3 if you also have business income. Most salaried employees use ITR-1.
What documents do I need to file ITR?
Essential: Form 16 (Part A and Part B from employer), Form 26AS, AIS, bank statements, PAN and Aadhaar. Additional if applicable: investment proofs (PPF, ELSS, NPS), health insurance receipts, home loan interest certificate, rent receipts, capital gains statements.
What is Form 26AS and why is it important?
Form 26AS is the government's record of all TDS deducted against your PAN, advance tax paid, and self-assessment tax payments. It is the master reconciliation document for ITR filing. Any discrepancy between your ITR and Form 26AS triggers scrutiny notices. Always match Form 16 data with Form 26AS before filing.
How do I e-verify my ITR?
The easiest method is Aadhaar OTP — generated on the income tax portal and sent to your Aadhaar-linked mobile. Must be completed within 30 days of ITR submission. Other methods include net banking EVC, bank account EVC, and DSC. Physical ITR-V by post is still valid but slow.
What is the late filing fee if I miss July 31?
Late filing fee under Section 234F: Rs 1,000 if total income is below Rs 5 lakh; Rs 5,000 if income exceeds Rs 5 lakh. Additionally, interest under Section 234A at 1% per month on unpaid tax accrues from August 1. Capital losses cannot be carried forward in belated returns.
Can I file a revised ITR after submission?
Yes. Revised returns under Section 139(5) can be filed any number of times up to December 31, 2025 for AY 2025-26. The revised return supersedes the original. You can revise even a belated return. Revisions are useful for correcting missed deductions, additional income discovered, or bank interest figures.
What is the Annual Information Statement (AIS)?
AIS is a comprehensive statement on the income tax portal showing all financial transactions reported to the department: salary, interest, dividends, stock and mutual fund trades, property transactions, foreign remittances, and more. Unlike Form 26AS which shows only TDS, AIS shows all reportable income. Review AIS before filing to ensure you include all income and avoid notices.
