If you have ever put off filing your income tax return because it sounded complicated, you are not alone. Every year, lakhs of first-time filers in India sit with the same question: where do I even start? The good news is that learning how to file ITR in India is far simpler than it looks, especially now that almost the entire process happens online. If you can book a train ticket or pay a bill on your phone, you can file your return.
An income tax return, or ITR, is simply a statement you send to the Income Tax Department each year declaring what you earned and what tax you paid on it. Filing it is not the same as paying tax. Many people who file a return actually get money back, because their employer or bank deducted more tax during the year than they finally owed.
This guide walks you through the whole thing — who needs to file, what to keep ready, which form to pick, and the actual steps on the portal — using a realistic example throughout.
Who Has to File an ITR?
The simplest rule is income. If your total income in a financial year crosses the basic exemption limit, you are expected to file. Under the old regime that limit is ₹2.5 lakh a year for most individuals below 60. Under the new regime it is ₹3 lakh. So a salaried person earning, say, ₹9 lakh a year definitely needs to file.
But income is not the only trigger. You must file a return even if your income is below the limit when certain conditions apply. Spent more than ₹2 lakh on foreign travel in a year? Deposited more than ₹1 crore in your bank accounts? Paid electricity bills above ₹1 lakh in a year? Bought or sold property above a threshold? Any of these makes filing mandatory. The same applies if you have foreign assets, hold a foreign bank account, or run a business with turnover above the audit threshold.
Then there are the cases where filing is not strictly compulsory but still makes sense. Your employer may have deducted TDS from your salary even though your total income is low. Your bank may have deducted TDS on fixed deposit interest. The only way to claim that money back is to file a return. A filed return also doubles as proof of income, which banks ask for when you apply for a home loan, a car loan, or even a visa.
Documents to Keep Ready Before You Start
A lot of the stress around filing comes from hunting for papers at the last minute. Spend twenty minutes gathering everything first, and the actual filing takes far less time.
Start with your PAN card and Aadhaar card. Your PAN is the key to the whole process — your return is filed against it. Your Aadhaar should be linked to your PAN; if it isn’t, link it first on the income tax portal, because an unlinked PAN can create problems later.
Next, your Form 16. If you are salaried, your employer gives you this after the financial year ends, usually by mid-June. It shows your total salary, the TDS your employer deducted, and the exemptions you claimed, like HRA. If you changed jobs during the year, collect a Form 16 from each employer. Both count.
Then gather your bank statements and interest certificates. Your savings account interest, fixed deposit interest, and recurring deposit interest are all taxable income, and people forget this more than anything else. Ask your bank for an interest certificate, or download one from net banking. It takes five minutes and saves you a mismatch notice later.
Keep your investment and deduction proofs in one folder too — your ELSS statements, PPF passbook, life insurance premium receipts, and health insurance premium receipts. You will need them if you are claiming deductions under sections like 80C or 80D. If you want a quick refresher on what else you can claim, our guide on how to save tax beyond 80C (https://smartfinanceindia.com/how-to-save-tax-beyond-80c-india/) is a useful companion read.
Finally, keep your Form 26AS and Annual Information Statement (AIS) handy. Both are available free on the income tax portal. They show the tax already deducted on your behalf and the income the department already knows about — salary, interest, dividends, even mutual fund redemptions. Cross-checking your return against these two documents is the best way to avoid a notice.
Choosing the Right ITR Form
This is the step that worries beginners the most, and it shouldn’t. For most people, the choice is between two forms. Here is a plain-English chooser.
| Your situation | Form to use |
|---|---|
| Salary or pension, one house property, other income like FD interest, total income up to ₹50 lakh | ITR-1 (Sahaj) |
| Salary plus capital gains, more than one house property, foreign income, or income above ₹50 lakh | ITR-2 |
| Income from a business or profession | ITR-3 |
| Presumptive income from a small business or profession | ITR-4 (Sugam) |
Take our example. Rohan earns ₹9 lakh a year from his job, has a fixed deposit that paid ₹18,000 in interest, and a savings account that earned ₹6,000. No shares sold, no second house, no business. He fits ITR-1 perfectly. If Rohan had sold some shares during the year and made a capital gain, he would move to ITR-2. The form matters because filing the wrong one is one of the most common mistakes — the department can treat a return filed on the wrong form as defective, and you would have to file it again.
New Regime or Old Regime? Decide Before You File
When you file, you will be asked to choose between the new and old tax regimes. This choice decides how much tax you pay, so it is worth a minute of thought.
Under the old regime, your taxable income goes down because of deductions — 80C investments up to ₹1.5 lakh, HRA, health insurance under 80D, home loan interest, and so on. Under the new regime, the slab rates are lower but most deductions disappear. The new regime is the default now, so if you do nothing, you are in it.
A quick rule of thumb: if your total deductions add up to more than about ₹2 lakh in a year, the old regime usually wins. If you don’t claim many deductions — you rent a house without HRA, you don’t invest much under 80C — the new regime is often better. For Rohan, whose employer gives him HRA and who puts ₹1.5 lakh into ELSS and PPF, the old regime probably saves him money. But this is genuinely a maths question, and the right answer changes from person to person. Our comparison of the new vs old tax regime (https://smartfinanceindia.com/new-vs-old-tax-regime-india/) works through the numbers with examples.
One reassuring detail: if you are salaried, you can switch regimes every year when you file. You are not locked in forever. Non-salaried taxpayers have stricter rules, so if you run a business, check before you switch.
How to File ITR in India: Step by Step
Here is the actual filing process on the income tax portal, incometax.gov.in. Set aside 30 to 45 minutes, keep your documents beside you, and go slowly.
Step 1: Log in to the portal
Go to incometax.gov.in and log in with your PAN as your user ID and your password. First time here? Register with your PAN, verify with an OTP sent to your registered mobile number, and set a password.
Step 2: Start a new return
From the dashboard, go to e-File, then Income Tax Return, then File Income Tax Return. Select the assessment year carefully. This trips people up every year. If you are filing for income earned between April 2025 and March 2026, the assessment year is 2026-27. The assessment year is always the year after the financial year in which you earned the money.
Step 3: Pick your filing mode and form
The portal will ask whether you want to file online or offline. For a beginner, online is easier — the form fills itself in with much of your data. Then select the right ITR form using the chooser above. In Rohan’s case, ITR-1.
Step 4: Check the pre-filled details
Here is where the portal does the heavy lifting. Your salary details, TDS, bank interest, and dividend income often appear pre-filled from your Form 16, Form 26AS, and AIS. Go through each section and check the numbers against your own documents. If a salary figure looks wrong, fix it. Pre-filled does not mean perfect — it means mostly right.
This is also where you add income the portal may not know about. Rent from a property you let out, freelance income, interest from a savings account at a small bank — if it isn’t in the AIS, add it yourself. Leaving income out is not a shortcut. The department’s data matching gets better every year, and an omission discovered later costs far more than the tax would have.
Step 5: Claim your deductions
Move to the deductions section and enter your 80C investments, health insurance premiums, and any other deductions you are eligible for. Enter the actual amounts from your receipts, not round figures from memory. If you are in the new regime, most of these sections won’t apply — the portal will grey them out — which is normal.
Step 6: Review the tax calculation
Before you submit, the portal shows you a summary: total income, deductions claimed, tax payable, tax already paid through TDS and advance tax, and the final figure — either tax due or a refund. Read this screen properly. If it says a refund of ₹4,200 is due to you, that’s the department telling you it owes you money. If it says ₹3,500 is payable, you need to pay it before submitting — the portal will let you pay through net banking or UPI, and the challan gets linked to your return automatically.
Step 7: Submit and e-verify
Hit submit. You have filed — but the job is not quite done. A return that is filed but not verified is treated as if it was never filed at all. You have 30 days from filing to e-verify, and it is best to do it the same day.
E-Verification: The Step You Must Not Skip
E-verification confirms that the return is really yours. The easiest method for most people is Aadhaar OTP: the portal sends a one-time password to the mobile number linked to your Aadhaar, you enter it, and you are done in under a minute. Other options include net banking — log in through your bank’s website and verify from there — or a bank account-based OTP, or sending a signed physical copy of the ITR-V acknowledgement to the CPC office in Bengaluru by post.
What Happens After You File
Once your return is verified, the department processes it. Processing usually takes anywhere from a few weeks to a couple of months. You will receive an intimation under section 143(1) on your registered email — this is a statement comparing the tax you calculated with the tax the department calculated. In most straightforward cases, the two match and nothing more is needed.
If a refund is due, it is credited directly to the bank account you mentioned in your return. Refunds typically arrive within two to six weeks of processing, though it can take longer during peak season. Make sure the bank account in your return is active and pre-validated on the portal, or the refund will bounce back.
Sometimes the intimation shows a small difference, a few hundred rupees, because of a rounding or a mismatch in interest figures. Read it before reacting. If the department’s figure is right, pay the difference. If you believe yours was right, you can respond to the intimation online or file a rectification. Don’t ignore it — unanswered intimations have a habit of turning into notices.
Common Mistakes That Cost Beginners
Most filing problems come from a handful of avoidable errors. Picking the wrong form is the first — a person with capital gains filing ITR-1, or a business owner filing ITR-4 when they should be on ITR-3, will get a defective-return notice. Use the chooser table above and don’t guess.
The second is forgetting income. Fixed deposit interest is the classic one — it doesn’t arrive in your account with a label on it, so people forget it exists. Savings account interest, dividends, even a small amount of freelance work all count. Your AIS knows about most of these, so compare your return with it before submitting.
The third is not verifying the return. Filing without e-verifying is the most pointless mistake in the whole process because the return simply doesn’t count. Verify the same day you file.
The fourth is entering the wrong bank account or an old one. Your refund goes where you tell it to go. If that account is closed, the refund fails and you spend weeks sorting it out.
And the fifth is waiting until the last day. The portal slows down badly in the last week of July every year. Servers crawl, OTPs arrive late, and one failed session can cost you an evening. Filing in June, when your Form 16 is in hand and the portal is quiet, is the calmest way to do it.
What Happens If You File Late
The usual deadline for individuals is 31 July of the assessment year. Miss it and the return can still be filed — it’s called a belated return — but there is a price.
A late fee applies under section 234F: ₹5,000 if you file after the deadline. If your total income is below ₹5 lakh, the fee is capped at ₹1,000. On top of that, interest is charged under section 234A at 1% per month on any unpaid tax, and you lose the ability to carry forward certain losses, like capital losses, to future years. You also can’t revise a belated return as freely as a timely one.
None of this is a disaster — the department would much rather you file late than not file at all — but it is money and flexibility lost for no reason. If you realise you missed the deadline, file as soon as you can. The fee is the same whether you file one day late or three months late, so delaying further only adds interest.
A Last Word
Filing your first ITR feels like a bigger deal than it is. Most of your data arrives pre-filled, and the whole process takes less than an hour once your documents are ready. The habit matters more than any single year’s return — a clean filing record builds your financial profile year by year, making loans easier and any future scrutiny much simpler to handle. So gather your Form 16, check your AIS, pick the right form, and file early. Next year, when July rolls around, you’ll wonder why the first time felt so daunting.
