How to File ITR 2026: Forms, Last Date, Refund & 143(1)

📄🚀 What ITR Filing Means and Who Must File

An income tax return, or ITR, is how you declare your year's income, deductions and tax paid to the government. You file it online on the official portal.

You must file if your total income crosses the basic exemption limit for your regime. Filing is also required in some cases even below that, such as high spending or foreign assets.

Even when not strictly required, filing is worth it. An ITR is solid proof of income for loans, visas and credit cards, and it is needed to claim a refund.

If your employer cut more TDS than your actual tax, only filing gets that money back. The government does not refund excess tax on its own.

The financial year and assessment year confuse many people. You earn income in a financial year, then file for it in the next year, called the assessment year.

So income from April 2025 to March 2026 is FY 2025-26, and you file it in AY 2026-27. Always pick the assessment year, not the financial year, on the portal.

Filing builds a financial track record over the years. Lenders and embassies often ask for two or three years of returns, so consistent filing helps later.

If this is your first time, do not be intimidated. A simple salaried return on the official portal is far easier than it looks once your documents are ready.

📋🧾 Which ITR Form Should You Use

Picking the right form matters, because the wrong one can make your return defective. The form depends on your income type, not your job title.

ITR-1 (Sahaj) is for most salaried people with income up to ₹50 lakh from salary, one house and interest. It is the simplest form.

ITR-2 is for those with capital gains, more than one house, or foreign income, but no business income. ITR-3 is for business or professional income.

ITR-4 (Sugam) is for small business or professional income under the presumptive scheme. If unsure, the portal often suggests the right form based on your data.

Income from salary, one house and bank interest is the simplest case, and ITR-1 handles it. The moment you add capital gains, ITR-1 no longer fits.

Freelancers and consultants usually fall under business or professional income, so ITR-3 or ITR-4 applies to them. Filing ITR-1 by mistake here causes problems.

When you genuinely cannot decide, the portal's guided filing asks a few questions and points you to the right form. It is a safe fallback.

Getting the form right the first time saves a lot of trouble. A wrong form can make the whole return defective, forcing you to file again.

🔢🪜 The Filing Steps in Detail

Start by gathering Form 16 from your employer, your AIS and Form 26AS from the portal, plus bank and investment proofs. These hold most of your numbers.

Log in at incometax.gov.in with your PAN and password. Select the assessment year, currently AY 2026-27 for income earned in FY 2025-26.

Choose the correct ITR form and let the portal pre-fill your salary and TDS. Cross-check every figure against your own documents before accepting.

Claim your eligible deductions, review the tax summary, then submit. The return is not done until you e-verify it, which is the step people forget.

The AIS, or Annual Information Statement, is your friend here. It lists income the department already knows about, from salary to interest to large transactions.

Reconcile your return with the AIS before you submit. If your figures do not match what the department has, that mismatch is the top cause of a notice.

Save a draft as you go. The portal lets you return later, so you do not lose work if you need to fetch a missing document mid-way.

Use the pre-fill, but never trust it blindly. The portal pulls a lot automatically, yet you are responsible for the final numbers, so verify each one.

Take your time on the review screen. A few minutes checking each figure now saves weeks of dealing with a notice later.

📑🚀 Documents You Need to File

You do not need a thick file, but a few documents make filing smooth. Most numbers come from just three or four sources.

Form 16 from your employer summarises your salary and the TDS deducted. It is the backbone of a salaried return.

Your AIS and Form 26AS, downloaded from the portal, show all income and tax credits the department has on record. Bank interest certificates fill the rest.

Keep your investment proofs for deductions, like 80C receipts and insurance premiums, especially if you use the old regime. PAN and a validated bank account complete the set.

Download the AIS and 26AS fresh each year before filing. They update through the year as employers and banks report, so an old copy may be incomplete.

📊📋 Filing Essentials

💼💰 Filing for Salary, Freelance and Other Income

A salaried person with only salary, one house and interest has the easiest return, usually ITR-1. Form 16 does most of the work.

A freelancer or consultant reports professional income, often under the presumptive scheme in ITR-4, which lets you declare a fixed percentage as profit.

If you trade in stocks or sell property, capital gains push you into ITR-2 or ITR-3. These need your broker statements and purchase records.

Many people have a mix, like salary plus some freelance work. In that case the business income decides the form, so you move up from ITR-1.

Whatever your income mix, report all of it. Leaving out a small freelance payment or interest income is exactly what the AIS catches and flags.

Pensioners file much like salaried people, usually ITR-1, using the pension and any interest income. The process is the same straightforward route.

Keep records through the year, not just at filing time. A simple folder of payslips, interest certificates and proofs turns a stressful July into a quick task.

⚖️⚖️ Old Regime vs New Regime

At filing you choose between the old and new tax regimes. The new regime is now the default if you do nothing.

The old regime lets you claim deductions like 80C, 80D and home loan interest, but has higher slab rates. It suits people with big deductions.

The new regime has lower slab rates but removes most deductions. It often suits those who do not invest heavily in tax-saving instruments.

Run both before deciding. Our Section 80C guide and a tax calculator help you compare, since the better choice depends entirely on your deductions.

There is no permanently right answer. A person with a home loan and heavy 80C investments often saves more in the old regime.

Someone who does not invest much for tax saving usually pays less under the new regime's lower rates. The only way to be sure is to compute both.

Once you file, your regime choice for that year is largely locked. So compare carefully before submitting, rather than discovering a better option afterwards.

📈📊 Old vs New Regime at a Glance

If you miss the filing deadline and file belated, you cannot choose the old regime. The new regime applies automatically.

📅🧾 ITR Last Date for AY 2026-27

For FY 2025-26 (AY 2026-27), the deadline is no longer a single date for everyone. It now depends on which form you file.

Salaried filers using ITR-1 or ITR-2, with no audit, must file by 31 July 2026. This covers most ordinary taxpayers.

Business and professional income on ITR-3 or ITR-4, where no audit is needed, gets until 31 August 2026. Audit cases get 31 October 2026.

If you miss your date, you can still file a belated return up to 31 December 2026, with a late fee and interest. Last year's extension was a one-off, so plan for your date.

Filing opens around the start of the financial year, but most people wait until July. Filing early avoids the last-week portal rush and gets your refund sooner.

Do not bank on a deadline extension. Last year saw one because forms came late, but that is not guaranteed, so treat your date as firm.

Mark your specific date based on your form. A salaried person and a small business owner now have different deadlines, so know which one is yours.

Set a personal reminder a week before your date. That buffer gives you room to fix a missing document without missing the deadline itself.

💸🚀 Your Refund and How to Track It

If you paid more tax than you owed, the extra comes back as a refund after your return is processed. It is credited to your pre-validated bank account.

Refunds usually arrive within a few weeks of e-verification, often in 30 to 45 days, once the department processes the return. Filing early means an earlier refund.

Track it on incometax.gov.in under your filing history, or on the NSDL refund status page using your PAN and assessment year. The status shows each stage.

If a refund is delayed, check that your bank account is pre-validated and your return is e-verified. Both are common reasons a refund gets stuck.

Pre-validate your bank account on the portal before filing. A refund can only be credited to a validated account linked to your PAN.

If the refund fails, it is usually a bank detail issue. Fix the account, raise a refund reissue request on the portal, and it is sent again.

Do not fall for messages promising to speed up your refund for a fee. The department never charges for refunds, and such messages are scams.

Patience helps after filing. Refunds depend on the department's processing queue, which is busiest right after the deadline, so early filers are served sooner in the queue.

File early in the season if a refund is due. Early returns are processed sooner, so your money comes back faster.

📬📨 Understanding the 143(1) Intimation

After processing, you get an intimation under Section 143(1) by email. This is normal and is not a scary notice by itself.

It simply compares your figures with the department's calculation. It shows one of three results: a refund due, no difference, or extra tax demanded.

If it matches your return with no demand, you do nothing. If it shows a refund, that is on its way to your bank.

If it shows a demand or a mismatch you disagree with, respond on the portal within the time given. The intimation is password protected, opened with your PAN and date of birth.

Keep this intimation safe. It is your official record that the return was processed and shows the final accepted figures.

If you genuinely disagree with a demand in it, you can file a rectification request online. Do not ignore a real demand, as interest keeps adding up.

Most intimations are simple confirmations. Treat the email calmly, open it with your password, and read the comparison table before assuming anything is wrong.

If the intimation shows a refund smaller than you expected, the comparison table tells you why. Read which figure the department adjusted before you react.

In short, the 143(1) intimation is part of normal processing, not a reason to worry. Read it, keep it, and act only if it shows a genuine demand.

🚫⚠️ Common Mistakes That Trigger Notices

The most common error is a mismatch between your return and your AIS or Form 26AS. The department now flags these automatically, so reconcile them first.

Picking the wrong ITR form is another. A salaried person with capital gains who files ITR-1 instead of ITR-2 can get a defective return notice.

Forgetting to report interest income, or income from a previous job, is a frequent trigger. The AIS captures these, so leaving them out invites a mismatch.

And of course, not e-verifying. An unverified return is invalid, so all the effort is wasted if you skip that final step.

Another quiet mistake is using the wrong assessment year. Filing under the previous year by accident creates confusion and may need a fresh filing.

Claiming deductions you cannot prove is risky too. Only claim what you have documents for, since the department can ask for proof later.

Double-check your bank and personal details before submitting. A wrong account number or IFSC quietly blocks your refund even when the return is perfect.

Filing in a last-minute rush is itself a mistake. Errors creep in under time pressure, and a jammed portal near the deadline adds avoidable stress.

🔄📈 Belated, Revised and Discarded Returns

If you miss the due date, a belated return lets you still file, up to 31 December 2026, with a late fee. It is better than not filing at all.

If you filed but spotted an error, a revised return corrects it. You can revise before the end of the assessment year, replacing the original.

There is also a discard option, which lets you delete an unverified return entirely and start fresh, as long as you had not e-verified it.

An updated return, or ITR-U, is a separate route to fix or declare income for older years, within the allowed window, usually with extra tax.

A belated return has real costs beyond the fee. You cannot carry forward most losses, and you lose the old regime option, so the early date is worth meeting.

If you are unsure whether to revise, remember a revised return fully replaces the original. File it carefully, because it becomes your return of record.

The discard option is genuinely useful if you realise, before verifying, that you filed wrongly. It is cleaner than revising a return you never confirmed, as your final return of record.

Filing ITR is not just a duty. It is how you reclaim excess tax, build a financial record for loans and visas, and stay clear of penalties and notices.
