Income Tax Return (ITR) Filing in India: A Beginner's Guide (2026)
If the words "income tax return" make you nervous, you're not alone — for millions of first-time filers in India, the ITR feels far more complicated than it actually is. The truth is that for most salaried people, filing is a short, online process. And with the deadline for salaried individuals falling on 31 July 2026 for the financial year 2025–26, now is the time to understand it. This guide walks you through who needs to file, which form to use, what to keep ready, and how to do it — in plain language.
What is an ITR, and who needs to file one?
An Income Tax Return (ITR) is a form you submit to the Income Tax Department declaring your income, deductions, and the tax you've paid for a financial year. You generally need to file if:
- Your total income for the year is above the basic exemption limit.
- You want to claim a refund of extra tax deducted (TDS).
- You have foreign income or assets, or meet certain high-value transaction conditions.
Even when it isn't strictly mandatory, filing is often worth it — which brings us to the next point.
Why filing matters, even if your tax is zero
Many beginners assume that if their employer already deducted TDS, there's nothing to do. Filing still helps you in real ways:
- Refunds. If excess tax was deducted, filing is the only way to get it back.
- Proof of income. ITRs are widely accepted for visa applications, and by lenders when you apply for a loan or credit card.
- Carrying forward losses. Filing on time lets you carry certain losses forward to future years.
- A clean record. Regular filing keeps you compliant and avoids notices later.
Which ITR form is for you?
Choosing the right form trips up a lot of first-timers. Here's a simple guide for common cases:
| Form | Who it's usually for |
|---|---|
| ITR-1 (Sahaj) | Salaried individuals with income up to ₹50 lakh from salary, one house property, and other sources like interest |
| ITR-2 | Individuals with capital gains, more than one house property, or foreign income |
| ITR-3 | Individuals with income from a business or profession |
| ITR-4 (Sugam) | Presumptive income from a small business or profession |
If you're a salaried employee with a straightforward income, ITR-1 is very often the right choice. When in doubt, check the current criteria on the official portal before you start.
Old and new tax regimes: a quick note
Since a few years ago, India has offered two ways to calculate your tax: the old regime, which lets you claim many deductions and exemptions (like Section 80C investments and house rent allowance), and the new regime, which has lower slab rates but removes most of those deductions. The new regime is now the default, but you can still choose the old one if it works out cheaper for you.
For a beginner, the practical takeaway is simple: if you have meaningful deductions — insurance, PPF, ELSS, home loan interest, rent — the old regime may save you more. If you have few deductions, the new regime is usually simpler and lighter. Many filers compare both once at filing time and pick whichever gives the lower tax; the portal helps you see the difference before you commit.
Documents to keep ready
Gathering everything first makes filing much faster. For most salaried filers you'll want:
| Document | Why you need it |
|---|---|
| PAN and Aadhaar | Identity and mandatory linking |
| Form 16 | Your employer's summary of salary and TDS |
| Bank statements | Interest income and account details for refunds |
| Investment proofs | To claim deductions (for example under Section 80C) |
| Form 26AS / AIS | To cross-check the tax already credited against your PAN |
Keeping these in one folder before you log in saves you from stopping halfway.
How to file, step by step
The exact screens change year to year, but the flow is consistent:
- Register or log in on the official Income Tax e-filing portal using your PAN.
- Choose the correct assessment year (for income earned in 2025–26, that's AY 2026–27).
- Select the right ITR form and filing mode.
- Review the pre-filled data — salary, TDS, and interest are often filled in for you. Correct anything that looks wrong.
- Add any deductions you're eligible for, and confirm the tax payable or refund.
- Submit, and then e-verify — usually via an OTP linked to your Aadhaar. Filing is not complete until you verify.
That final e-verification step is the one beginners most often forget, so don't skip it.
Common mistakes to avoid
A few simple errors cause most of the trouble:
- Forgetting to e-verify — an unverified return is treated as not filed.
- Using the wrong form, which can make the return defective.
- Not reporting interest income from savings or fixed deposits.
- Ignoring Form 26AS/AIS, so the tax you claim doesn't match the department's records.
- Waiting until the last day, when the portal is busiest.
Key dates and penalties
For the financial year 2025–26 (assessment year 2026–27), the due date for most salaried individuals is 31 July 2026. Missing it can mean a late-filing fee under Section 234F — up to ₹5,000 — plus interest on any unpaid tax, and you may lose the ability to carry forward some losses. Filing a week or two early avoids both the penalty and the last-minute portal rush.
After filing: what happens next
Submitting isn't quite the end. Once you've e-verified, the Income Tax Department processes your return, and you'll get an intimation under Section 143(1) confirming whether their calculation matches yours. If a refund is due, it's credited directly to your pre-validated bank account, often within a few weeks. It's worth keeping an eye on your filing status on the portal until you see it marked as processed. If there's a mismatch or a query, you may receive a notice — usually nothing to panic about, but respond within the time given. Holding on to your filed ITR, Form 16, and proofs for a few years is a good habit, in case you ever need to refer back.
Common questions
Do I have to file if my employer already deducted TDS? Often yes — filing is how you claim any refund and stay compliant. TDS deduction and filing your return are two separate things.
What happens if I miss the 31 July deadline? You may still file a belated return later, but with a late fee under Section 234F and interest on unpaid tax, and some benefits like carrying forward losses can be lost.
Which ITR form should a salaried beginner use? For most salaried people with income up to ₹50 lakh and simple sources, ITR-1 (Sahaj) is the usual choice. Confirm the current eligibility before filing.
Is filing an ITR free? Yes, filing on the official government portal is free. You only pay if you choose a paid service or professional to help you.
How do I get my refund faster? File early, make sure your bank account is pre-validated and linked to your PAN, and complete e-verification immediately after submitting.
