Why You Must File ITR — Even if Your Tax is Zero

Many salaried employees assume that since their employer deducts TDS (Tax Deducted at Source), they don't need to file an ITR. This is a common and costly mistake. Filing your ITR is mandatory if your gross income exceeds ₹2.5 lakh per year (₹3 lakh for senior citizens), regardless of whether TDS covers your entire tax liability.

Beyond compliance, ITR filing gives you several practical benefits:

⚠️ Penalty for late filing: Missing the July 31 deadline attracts a penalty of ₹5,000 (₹1,000 if total income ≤ ₹5 lakh). Belated returns cannot be filed after December 31 of the assessment year.

Which ITR Form Should You Use?

The Income Tax Department has different forms for different types of income. Choosing the wrong form can result in your return being marked defective. Here's a quick guide:

FormWho Should Use It
ITR-1 (Sahaj)Salaried employees with income from salary + one house property + other sources (bank interest, dividends). Total income must be below ₹50 lakh. Most common form.
ITR-2Individuals with capital gains from stocks/MF/property, or income from more than one house property, or foreign income/assets. Also for directors of companies.
ITR-3Self-employed professionals and business owners with business/profession income (in addition to other sources).
ITR-4 (Sugam)Individuals with income from business/profession under the Presumptive Taxation Scheme (Section 44AD/44ADA) with turnover below ₹2 crore.

If you are a salaried employee with income only from salary, savings account interest, dividends, and maybe some rent from one property — use ITR-1. If you sold any stocks or mutual fund units in the year, switch to ITR-2.

Documents to Gather Before You Start

Keep these ready before you log in to the income tax portal. Trying to find them mid-filing is frustrating and can lead to mistakes.

Step-by-Step: Filing ITR on incometax.gov.in

1

Log in to the Income Tax Portal

Go to incometax.gov.in. Log in with your PAN (as user ID) and password. If it's your first time, register using your PAN — you'll need Aadhaar OTP for verification. Once logged in, go to e-File → File Income Tax Return.

2

Select Assessment Year and Filing Mode

Select Assessment Year 2026-27 (for income earned in FY 2025-26). Choose "Online" mode for the easiest experience. The portal pre-fills many fields from Form 26AS and AIS — review them carefully for accuracy.

3

Select ITR Form and Tax Regime

Choose ITR-1 for most salaried individuals. The system may suggest a form based on your income details. You'll also need to select your tax regime — New or Old. The portal will show your estimated tax under both — choose whichever results in lower tax. You can switch regime every year when filing the return (New Regime is the default from FY 2023-24 onwards).

4

Verify and Fill in Income Details

The portal pre-fills salary income from Form 26AS. Cross-check with your Form 16. Add any other income — savings account interest, rental income, dividends. Under the Old Regime, fill in all deductions: 80C investments, HRA, home loan interest, 80D health insurance premiums, and NPS contributions under 80CCD(1B).

5

Verify Tax Computation and Check for Refund

The portal calculates your tax automatically. If total tax payable is less than TDS already deducted, the difference is your refund amount — it will be credited to your bank account within 4–6 weeks of filing. If you owe additional tax, pay it via the Self-Assessment Tax option before submitting.

6

Preview and Submit the Return

Review every section — personal details, income, deductions, tax paid. Once satisfied, click Preview Return and then Submit. You'll get an acknowledgement number (ITR-V) immediately. This proves your return has been filed.

7

E-Verify Your Return (Mandatory)

Filing is NOT complete until you e-verify. You have 30 days from submission. Verification options: Aadhaar OTP (fastest), Net Banking, Bank Account EVC, Demat Account EVC, or Digital Signature Certificate. Alternatively, send the signed ITR-V printout by post to CPC Bengaluru — but this takes 4–5 weeks.

New Regime vs Old Regime — Which Should You Choose?

The New Tax Regime (default from FY 2023-24) has lower slab rates but no deductions. The Old Regime allows Section 80C, HRA, home loan interest, NPS, and other deductions. The choice depends on your deductions:

Your SituationLikely Better Regime
No investments, no home loan, paying rent in non-metroNew Regime
Maxing 80C (₹1.5L) + health insurance 80D + NPS (₹50k)Old Regime (usually)
Home loan in metro city + HRA + 80COld Regime (calculate carefully)
Income below ₹7.75 lakh/year (after std deduction)New Regime (zero tax)
Very high income (₹30L+) with limited deductionsNew Regime (lower surcharge)

The simplest rule: use our income tax calculator — enter your income and deductions and it instantly shows the tax under both regimes and which saves more.

After Filing: What to Check

Once you've e-verified your ITR, the Central Processing Centre (CPC) in Bengaluru processes it. You'll receive an intimation under Section 143(1) at your registered email — usually within 4–8 weeks. This intimation tells you if the return was processed correctly, if there are any discrepancies, or if a refund has been issued.

Check your Form 26AS periodically to confirm TDS credits match what your employer and banks have deposited. Mismatches must be resolved with the deductor before the return is processed.

Frequently Asked Questions — ITR Filing India

Do I need to file ITR if my income is below ₹5 lakh?
If your gross income exceeds ₹2.5 lakh (₹3L for seniors), you must file even if the 87A rebate makes your final tax liability zero. Exception: resident individuals with income only from salary (and TDS is fully covered) may not be required to file if gross income is ≤ ₹5 lakh. However, filing is still strongly recommended for refunds, visa, and loan purposes.
What is Form 26AS and why is it important?
Form 26AS is your consolidated tax statement — it shows all TDS deducted from your income by employers, banks, and others; advance tax you've paid; and any tax refunds received. The IT department uses 26AS to verify your ITR. If 26AS shows ₹50,000 TDS but your return claims only ₹40,000, you'll receive a deficiency notice. Always cross-check your Form 16 with 26AS before filing.
Can I revise my ITR after filing?
Yes. You can file a revised ITR if you discover a mistake — like forgetting to declare bank interest income or claiming the wrong deduction amount. You can revise your return any number of times before December 31 of the assessment year (December 31, 2026 for FY 2025-26 returns). The last revised return filed is considered the final one.
How long does it take to get an ITR refund?
Most refunds are processed within 4–6 weeks of filing and e-verification if your bank account is pre-validated on the portal. Refunds are credited directly to the bank account linked to your PAN. For FY 2025-26 returns filed by July 31, 2026, you should receive refunds by September–October 2026 in most cases.
What happens if I don't file ITR?
If you don't file by July 31 (the normal deadline), you can file a belated return by December 31 with a penalty of ₹5,000 (₹1,000 if income ≤ ₹5 lakh). After December 31, filing is not possible unless you receive a notice from the IT department. Persistently not filing can result in prosecution under Section 276CC for those with significant tax liability.
Should I use a CA or file myself?
For a straightforward salaried return (ITR-1 with only salary, interest, and standard deductions), filing yourself on the portal is easy and free. The portal pre-fills most data. Consider a CA if you have: capital gains from multiple assets, foreign income, multiple house properties, a side business, or a complicated deduction structure. CA fees for ITR-1/2 typically range from ₹500–₹2,000 per year.
