Filing your Income Tax Return (ITR) is a legal obligation for every eligible taxpayer in India. With the Income Tax Department's e-filing portal, you can now file your ITR entirely online from the comfort of your home. Whether you are a salaried employee, a freelancer, or a business owner, this comprehensive guide walks you through every step of the ITR filing process for Assessment Year 2026-27 (Financial Year 2025-26).
Who Must File ITR?
Not everyone is required to file an ITR, but the Income Tax Act mandates filing in several situations. Understanding whether you fall under the mandatory filing criteria is the first step.
Based on Gross Total Income
You must file ITR if your gross total income (before deductions) exceeds the basic exemption limit:
| Category | Old Regime Exemption | New Regime Exemption |
|---|---|---|
| Below 60 years | ₹2,50,000 | ₹3,00,000 |
| Senior Citizens (60-80) | ₹3,00,000 | ₹3,00,000 |
| Super Senior Citizens (80+) | ₹5,00,000 | ₹3,00,000 |
Mandatory Filing Cases
Even if your income is below the exemption limit, you must file ITR if you:
- Deposited ₹1 crore or more in one or more bank accounts during the financial year
- Spent ₹2 lakh or more on foreign travel
- Consumed electricity worth ₹1 lakh or more in a year
- Own foreign assets or have income from foreign sources
- Want to claim a tax refund
- Are a company or partnership firm (regardless of income)
- Had TDS or TCS deducted and want to claim credit
- Need to carry forward losses under any head of income
Documents Required for ITR Filing
Before you begin filing, keep the following documents ready. Having everything on hand ensures a smooth and error-free filing experience.
- PAN Card: Your Permanent Account Number is mandatory for all ITR filings. It serves as your login credential on the e-filing portal.
- Aadhaar Card: Linking Aadhaar with PAN is compulsory. If not linked, you cannot file ITR. You can link via the Income Tax portal or SMS.
- Form 16: Issued by your employer, this certificate contains details of your salary income and TDS deducted. It has two parts — Part A (TDS details) and Part B (salary breakup).
- Form 26AS: This is your annual tax statement available on the e-filing portal. It shows all taxes deducted on your behalf, advance tax paid, and high-value transactions reported by third parties.
- AIS and TIS: The Annual Information Statement (AIS) and Taxpayer Information Summary (TIS) provide a comprehensive view of your financial transactions including salary, interest, dividends, securities trades, and foreign remittances.
- Investment Proofs: Receipts for PPF, ELSS, LIC premiums, NPS contributions, home loan principal repayment, tuition fees, and other Section 80C investments.
- Bank Statements: Statements for all savings and current accounts to verify interest income and other credits. Also needed for pre-filling bank account details for refund.
- Home Loan Certificate: If you have a home loan, obtain the interest and principal repayment certificate from your bank to claim deductions under Sections 24 and 80C.
- Capital Gains Statement: If you traded in stocks or mutual funds, get a consolidated statement from your broker or CAMS/KFintech.
ITR Forms Explained
The Income Tax Department has notified seven ITR forms (ITR-1 through ITR-7). Choosing the correct form is critical — filing the wrong form will make your return defective. Here is a quick reference:
| Form | Who Should File | Key Conditions |
|---|---|---|
| ITR-1 (Sahaj) | Resident salaried individuals | Income up to ₹50 lakh from salary, one house property, other sources. No capital gains or business income. |
| ITR-2 | Individuals and HUFs | Income from salary, house property, capital gains, foreign income. No business/profession income. |
| ITR-3 | Individuals and HUFs with business income | Income from business or profession. Also applicable for partners in firms. |
| ITR-4 (Sugam) | Presumptive income taxpayers | Business income under Section 44AD, 44ADA, or 44AE. Income up to ₹50 lakh (profession) or ₹2 crore (business). |
| ITR-5 | Firms, LLPs, AOPs, BOIs | Partnership firms, LLPs, Association of Persons, Body of Individuals, and artificial juridical persons. |
| ITR-6 | Companies | All companies except those claiming exemption under Section 11 (income from charitable/religious trusts). |
| ITR-7 | Trusts, political parties, institutions | Entities claiming exemption under Sections 139(4A), 139(4B), 139(4C), or 139(4D). |
For most salaried individuals, ITR-1 is sufficient. If you have capital gains from stocks or mutual funds, you need ITR-2. Freelancers and small business owners with presumptive income can use ITR-4.
Step by Step: How to File ITR on Income Tax Portal
Follow these 8 steps to file your ITR online on the official Income Tax e-filing portal (incometax.gov.in):
- Step 1 — Register/Login: Visit incometax.gov.in and log in using your PAN (as user ID), password, and captcha. If you are a first-time filer, click "Register" and complete the registration using your PAN, Aadhaar, and mobile number.
- Step 2 — Go to e-File > Income Tax Return: Navigate to "e-File" in the top menu, select "Income Tax Return," and click "File Income Tax Return." Select the Assessment Year (2026-27 for FY 2025-26) and filing type (Original or Revised).
- Step 3 — Select Status and ITR Form: Choose your filing status — Individual, HUF, or Other. The portal will suggest the appropriate ITR form based on your income profile. You can override this if needed.
- Step 4 — Choose Reason for Filing: Select why you are filing — taxable income exceeds exemption limit, mandatory filing criteria met, or filing for a refund. This determines the applicable sections.
- Step 5 — Verify Pre-filled Data: The portal auto-populates your personal information, salary details, TDS, and bank interest from Form 26AS and AIS. Review every field carefully. Correct any discrepancies — especially bank account details (needed for refund) and address.
- Step 6 — Enter Income and Deductions: Fill in income details under all five heads: Salary, House Property, Business/Profession, Capital Gains, and Other Sources. Then claim deductions under Sections 80C, 80D, 80E, 80G, and others. The portal calculates your total taxable income and tax liability automatically.
- Step 7 — Pay Tax (if applicable): If there is a tax payable after accounting for TDS and advance tax, pay the balance using Challan 280 via net banking, debit card, or UPI. Enter the challan details in the ITR form. You can also pay via the "e-Pay Tax" option on the portal.
- Step 8 — Submit and Verify: Review the summary page showing your income, deductions, tax paid, and refund/payable amount. Click "Submit." You must verify your return within 30 days of filing. Verification can be done via Aadhaar OTP, net banking, bank account EVC, Demat EVC, or by sending a signed physical copy (ITR-V) to CPC Bengaluru.
After successful verification, the Income Tax Department processes your return. You can track the status on the portal or via the AIS app.
ITR Filing Due Dates 2026
Filing your ITR before the due date is important to avoid penalties and to carry forward losses. Here are the key due dates for FY 2025-26 (AY 2026-27):
| Category | Due Date | Late Filing Penalty |
|---|---|---|
| Individuals & HUFs | July 31, 2026 | Up to ₹5,000 under Section 234F |
| Businesses (Audit required) | October 31, 2026 | Up to ₹5,000 under Section 234F |
| Transfer Pricing cases | November 30, 2026 | Up to ₹5,000 under Section 234F |
| Revised Return | December 31, 2026 | Same as original due date |
| Belated Return | December 31, 2026 | ₹1,000 to ₹5,000 |
Note: If your total income is below ₹5 lakh, the late filing fee is capped at ₹1,000. If you miss the belated return deadline (December 31), you can file an Updated Return (ITR-U) within 24 months from the end of the relevant AY, but with additional tax of 25% to 50% on the tax payable.
Common ITR Filing Mistakes to Avoid
Filing errors can lead to notices, delays in processing, or loss of refunds. Here are the 7 most common mistakes taxpayers make:
- Choosing the wrong ITR form: Filing ITR-1 when you have capital gains or using ITR-2 when you have business income will make your return defective. Always verify eligibility before selecting the form.
- Not reporting all income: Many taxpayers forget to report interest from savings accounts, fixed deposits, recurring deposits, or small freelance income. The AIS captures all reported transactions — discrepancies will trigger a notice.
- Incorrect bank account details: If your bank account number or IFSC code is wrong, your refund will bounce back. Verify your pre-filled bank details and ensure the account is linked to your PAN and is active.
- Not matching Form 26AS / AIS: Cross-check the TDS shown in Form 26AS with your Form 16. Ensure all high-value transactions in AIS (property purchases, stock trades, foreign remittances) are reported in your ITR.
- Forgetting to verify the return: An unverified ITR is treated as not filed. You have 30 days to verify after submission. Set a reminder and verify via Aadhaar OTP — it takes less than a minute.
- Claiming incorrect deductions: Claiming deductions you are not eligible for (like 80C for non-eligible investments or 80D for non-medical expenses) is a red flag. Keep all investment proofs handy and only claim what you are entitled to.
- Not filing even with zero tax liability: Even if your income is below the taxable limit, filing ITR is useful for visa applications, loan approvals, and carrying forward capital losses. It also serves as income proof.
How to Check ITR Status
After filing and verifying your ITR, you can check its status through multiple methods:
Method 1: Income Tax Portal
Log in to incometax.gov.in, go to "e-File" > "Income Tax Return" > "View Filed Returns." You will see the status of all filed returns — "Successfully e-Verified," "Processed," "Demand Determined," or "Refund Issued."
Method 2: SMS
Send an SMS from your registered mobile number: Type PAN STATUS and send it to 57575. You will receive an SMS with the current status of your return.
Method 3: AIS App
Download the "AIS for Taxpayer" app from Google Play or App Store. Log in with your PAN and OTP to view your return status, AIS data, and TIS summary in one place.
ITR Processing Time & Refund
After you verify your ITR, the Income Tax Department processes it and issues an Intimation under Section 143(1). Here is what to expect:
| Stage | Timeline | What Happens |
|---|---|---|
| Return Filed | Day 0 | You submit and verify the ITR |
| Processing | 7 to 120 days | CPC Bengaluru matches your data with Form 26AS, AIS, and TDS returns |
| Intimation u/s 143(1) | After processing | You receive an email with the tax computation — accepted as filed, adjusted, or with demand |
| Refund Issued | 20 to 45 days after processing | Refund is credited to your pre-validated bank account via ECS/NEFT |
How to track your refund: Visit tin.tin.nsdl.com/StatusTracker and enter your PAN and Assessment Year. You can also check on the e-filing portal under "My Account" > "Refund/Demand Status." If your refund is delayed beyond 90 days, you can raise a grievance on the e-filing portal or contact CPC at 1800-103-0025 (toll-free).
Interest on refund: If the refund is issued after April 1 of the assessment year, the government pays interest at 0.5% per month on the refund amount under Section 244A.

Can I file ITR without Form 16?
Yes, you can file ITR without Form 16. Use your salary slips, Form 26AS, and AIS to compute your income and TDS. Form 16 is a convenience document issued by your employer, but it is not mandatory for filing. However, ensure the salary income you report matches the TDS reflected in Form 26AS.
What happens if I miss the ITR filing deadline?
You can file a belated return until December 31, 2026 with a late fee of ₹1,000 to ₹5,000 under Section 234F. You will also lose the ability to carry forward losses (except house property loss). If you miss the belated deadline, you can file an Updated Return (ITR-U) within 24 months, but with additional tax of 25% to 50%.
Is it mandatory to link Aadhaar with PAN for ITR filing?
Yes, linking Aadhaar with PAN is mandatory as per Section 139AA of the Income Tax Act. If not linked, your PAN becomes inoperative, and you cannot file ITR, open bank accounts, or conduct high-value transactions. You can link via incometax.gov.in or by sending an SMS to 567678.
Can I revise my ITR after filing?
Yes, you can file a revised return any number of times before the end of the relevant Assessment Year (December 31, 2026 for AY 2026-27) or before the completion of assessment, whichever is earlier. Revised return replaces the original return completely — use it if you discover errors, missed income, or forgot to claim deductions.
How do I get a refund if I paid excess tax?
File your ITR with the correct tax computation. The Income Tax Department will automatically calculate the refund after processing your return. The refund is credited to your pre-validated bank account linked to your PAN. Ensure your bank account is validated on the e-filing portal under "My Profile" > "Bank Accounts."
