WHAT IS INCOME TAX E-FILING?

Income Tax e-Filing means submitting your income tax return electronically through the official Income Tax Department portal . Instead of filling out paper forms and standing in queues, you can now complete the entire process from your laptop or phone—in your pajamas, with a cup of chai.

Why E-Filing Matters in 2026

The Income Tax Department’s e-filing portal (https://www.incometax.gov.in) has been continuously upgraded to make filing more intuitive. For the Assessment Year 2026-27, the portal offers enhanced pre-filled data pulled directly from your Annual Information Statement (AIS) and Form 26AS, reducing manual entry errors significantly .

Who Must File ITR in 2026?

You are required to file an income tax return if :

• Your total income exceeds the basic exemption limit (₹3 lakh under new regime, ₹2.5 lakh under old regime for individuals below 60)

• You want to claim a refund of excess TDS or advance tax

• You wish to carry forward losses (business loss, capital loss)

• You have foreign income or foreign assets

• You have entered into specified high-value financial transactions

Even if your income is below the taxable limit, filing a Nil Return is recommended—it serves as proof of income for loans, visa applications, and builds financial credibility .

DOCUMENTS REQUIRED FOR ITR FILING 2026

Before you begin, gather these documents. Having everything ready beforehand turns a 45-minute task into a 20-minute one.

Compulsory Documents for Everyone

For Salaried Professionals

• Form 16: Issued by your employer, containing salary breakup and TDS details

• Salary slips (optional, for reference)

• House Rent Receipts: If claiming HRA exemption

• Investment Proofs: PPF, LIC, ELSS, NPS statements (for old regime claims)

For Those with Additional Income

• Interest Certificates: From banks on savings accounts, FDs, RDs

• Capital Gains Statements: From your broker or mutual fund house

• Rental Income Details: Rent receipts, bank statements

• Freelance/Business Income: Profit & loss statement, expense records

Pro Tip: Download your AIS and Form 26AS from the e-filing portal before you start. Compare them with your Form 16. Any mismatch? Address it with your employer or bank before filing .

HOW TO FILE INCOME TAX RETURN ONLINE: 10-STEP PROCESS

Here’s your step-by-step guide to file ITR online from home. Follow these steps in order, and you’ll be done in under an hour.

Step 1: Visit the Official E-Filing Portal

Go to https://www.incometax.gov.in/iec/foportal/

• If you’re a new user, click on “Register” and follow the registration process using your PAN .

• If you’re an existing user, click “Login” and enter your PAN (User ID), password, and captcha.

Step 2: Navigate to the ITR Filing Section

Once logged in :

• Click on the ‘e-File’ menu

• Select ‘Income Tax Returns’ > ‘File Income Tax Return’

Step 3: Select Assessment Year and Filing Mode

• Assessment Year: Select 2026-27 (this is for income earned in FY 2025-26)

• Mode of Filing: Choose ‘Online’ (you can also prepare offline and upload, but online is simpler for most)

• Click ‘Continue’

Step 4: Choose Your Filing Status and ITR Form

First, select your status: ‘Individual’

Now, choose the correct ITR form. This is critical—selecting the wrong form can render your return invalid .

If you’re a salaried employee with only salary income and maybe some bank interest, ITR-1 is your form.

Step 5: Verify and Confirm Pre-filled Data

This is where the new portal shines. The system will pre-fill many details from your AIS and Form 26AS .

You’ll see sections for:

• Personal Information: Name, PAN, Aadhaar, date of birth, address—verify everything

• Gross Total Income: Salary, interest, etc.—ensure it matches your Form 16 and AIS

• Deductions: If applicable

Crucial Check: Compare the pre-filled figures with your Form 16 and bank interest certificates. If something’s missing (like interest from a savings account), you must add it manually .

Step 6: Select Your Tax Regime

For FY 2025-26, the New Tax Regime is the default . You have two choices:

If you want the Old Regime, you must explicitly opt-out during filing. The system will show you a tax comparison—choose whichever benefits you more.

Step 7: Declare Income and Claim Deductions

• Income from Salary: Verify the pre-filled data from your Form 16

• Income from Other Sources: Add any interest income not pre-filled (savings account interest, FD interest)

• Deductions: If you’re in the old regime, claim your 80C, 80D, and other deductions here

The portal will automatically calculate your total tax liability based on your inputs and selected regime .

Step 8: Review, Compute Tax, and Pay (If Any)

• Click ‘Validate’ to run an error check

• The system will show your Tax Payable or Refund Due

• If tax is due, you can pay online via e-Pay Tax using Net Banking or UPI

• Once tax is paid (or if no tax is due), proceed to ‘Preview Return’

Step 9: Submit Your Return

• Review every section one last time

• Check that your income matches Form 26AS and AIS

• Click ‘Submit’

You’ll receive an Acknowledgement Number—note it down for future reference .

Step 10: E-Verify Your Return (Mandatory!)

Your return is not considered filed until it is verified . You have 30 days from submission to e-verify.

You can e-verify using :

• Aadhaar OTP (fastest—requires linked mobile number)

• Net Banking (through authorized banks)

• Bank Account EVC (if account is pre-validated)

• Demat Account EVC

• Digital Signature Certificate (for companies/audit cases)

If you don’t e-verify: Within 30 days, your return becomes invalid, and you’ll have to file again .

Alternative: If you cannot e-verify online, print the ITR-V (acknowledgement), sign it, and send it by ordinary/speed post to “Centralised Processing Centre, Income Tax Department, Bengaluru – 560500” within 30 days .

UNDERSTANDING THE 2026 TAX SLABS AND REBATES

To file accurately, you need to understand how your tax is calculated. Here are the updated rules for FY 2025-26 (AY 2026-27).

New Tax Regime Slabs (Default)

Key Benefits in New Regime:

• Standard Deduction: ₹75,000 for salaried individuals and pensioners

• Rebate under Section 87A: If your taxable income (after standard deduction) is up to ₹12,00,000, you get a full rebate—meaning zero tax for those earning up to ₹12.75 lakh

Old Tax Regime Slabs (Optional)

Choose the old regime only if your deductions (80C, 80D, HRA, home loan interest) significantly reduce your taxable income below what the new regime offers.

COMMON MISTAKES TO AVOID WHILE FILING ITR

Even experienced filers make errors. Here are the most common pitfalls and how to avoid them.

Mistake 1: Choosing the Wrong ITR Form

Filing ITR-1 when you have capital gains or foreign assets? Your return will be considered defective, and you’ll receive a notice . Always check the eligibility criteria for each form before proceeding.

Mistake 2: Ignoring Mismatches with AIS and Form 26AS

Your AIS captures almost all financial transactions—bank interest, stock sales, dividends. If the income you declare doesn’t match what’s in your AIS, the tax department’s system will flag it automatically .

Fix: Download AIS and Form 26AS before filing. Reconcile every item.

Mistake 3: Forgetting to Declare All Bank Accounts

You must declare all bank accounts you held during the year (except dormant accounts) . This includes accounts with zero balance. The department uses this for verification and refunds.

Mistake 4: Not Reporting Income from Previous Employment

Changed jobs? Income from both employers must be declared. Combine both Form 16s and enter total salary . Omitting one employer’s income causes TDS mismatches.

Mistake 5: Entering Incorrect Bank Details for Refund

A single digit wrong in your account number or IFSC code means your refund will be delayed or sent to the wrong account . Double-check before submitting.

Mistake 6: Filing but Not E-Verifying

This is the most common—and most avoidable—mistake. You file, breathe a sigh of relief, and forget to e-verify. Result? Your return is never processed .

Fix: E-verify immediately after submission using Aadhaar OTP. It takes 10 seconds.

Mistake 7: Missing the Deadline

The due date for most individuals is July 31, 2026 (tentative) . File after this, and you’ll face :

• Penalty under Section 234F: ₹5,000 (₹1,000 if income ≤ ₹5 lakh)

• Interest under Section 234A: 1% per month on unpaid tax

• Inability to carry forward certain losses

HOW TO CHECK YOUR ITR STATUS AND TRACK REFUND

After filing and e-verifying, you’ll want to know what’s happening. Here’s how to check.

Without Logging In

With Login

• Log in to the portal

• Go to ‘e-File’ > ‘Income Tax Returns’ > ‘View Filed Returns’

FREQUENTLY ASKED QUESTIONS

Q1: What is the last date to file ITR for FY 2025-26?

For individual taxpayers not requiring an audit, the deadline is July 31, 2026 (tentative). However, always check for official extensions on the income tax portal .

Q2: Can I file ITR without Form 16?

Yes. If you don’t have Form 16 (changed jobs, employer hasn’t issued, freelancer), you can file using:

• Salary slips for all 12 months

• Form 26AS (to get TDS details)

• Bank statements (for interest income)

Q3: Is it mandatory to link Aadhaar with PAN?

Yes. Your PAN must be linked with Aadhaar. If it’s not linked, your PAN becomes inoperative, and you cannot file your return or receive refunds .

Q4: What happens if I file ITR after the due date?

• Late fee under Section 234F: ₹5,000 (₹1,000 if income ≤ ₹5 lakh)

• Interest under Section 234A: 1% per month on unpaid tax

• You cannot carry forward certain losses (except house property loss)

Q5: I have income from freelance work. Which ITR form should I use?

If you have income from freelance work, business, or profession, you need ITR-3 (if maintaining books) or ITR-4 (if opting for presumptive taxation under Section 44ADA) . Do not use ITR-1 or ITR-2.

Q6: How do I claim a refund?

Refunds are automatically calculated when you file your return. To receive it :

• Ensure your bank account is pre-validated on the e-filing portal
