Which ITR Form Should I File? – Guide to Choosing the Right Income Tax Return Form

Last Updated on June 19, 2026

Choosing the correct Income Tax Return (ITR) form is one of the most important steps in filing your taxes accurately. The right form depends on three factors: who you are as a taxpayer (individual, HUF, firm, company, or trust), where your income comes from (salary, business, capital gains, etc.), and how much you earn in a financial year.

For FY 2025-26 (AY 2026-27), the Income Tax Department has revised several ITR forms, including expanded eligibility for ITR-1 and ITR-4 under the new Income Tax Act, 2025 framework. Filing the wrong form can get your return marked “defective,” delay your refund, or trigger a notice. This guide breaks down all seven ITR forms, the latest changes for this assessment year, due dates, and penalties for missing them.

What is an Income Tax Return?

An ITR is a form filed with the Income Tax Department declaring your income, taxes paid, deductions claimed, and final tax liability for a financial year. It helps you claim refunds, maintain financial records, and supports loan or visa applications. Filing it correctly using the right form is what makes all of this work without friction.

Which ITR Form Should I File?

Selection of the right Income Tax Return (ITR) form is imperative for accurate reporting and compliance with regulations. The choice of the form depends on the category of the individual and sources of income.

1. ITR-1 (Sahaj)

For resident individuals with total income up to ₹50 lakh, earning from salary or pension, up to two house properties (this is new for AY 2026-27 — earlier it was limited to one), and other specified income such as interest. You cannot use ITR-1 if you’re a company director, hold unlisted equity shares, have foreign assets, or have income above ₹50 lakh.

2. ITR-2

For individuals and Hindu Undivided Families (HUFs) who don’t have income from a business or profession but have capital gains, more than two house properties, foreign income/assets, or are company directors.

3. ITR-3

For individuals and HUFs with income from a business or profession. AY 2026-27 brings separate reporting requirements for F&O (futures and options) and intraday trading income within this form.

4. ITR-4 (Sugam)

For resident individuals, HUFs, and firms (excluding LLPs) opting for the presumptive taxation scheme under the Income Tax Act, with total income up to ₹50 lakh. Like ITR-1, eligibility now extends to up to two house properties. AY 2026-27 also requires additional disclosure of investment and bank balance details for ITR-4 filers.

5. ITR-5

For partnership firms, LLPs, Associations of Persons (AOPs), Bodies of Individuals (BOIs), and similar entities not covered under ITR-1 to ITR-4 or ITR-7.

6. ITR-6

For companies that do not claim exemption under Section 11 (income from property held for charitable or religious purposes).

7. ITR-7

For persons and entities required to file returns under Sections 139(4A), 139(4B), 139(4C), or 139(4D) – this includes charitable and religious trusts, political parties, research institutions, and similar entities.

Note: If you have no business or professional income, your choice is between ITR-1 and ITR-2. If you do have business or professional income, your choice is between ITR-3 and ITR-4 (presumptive scheme).

What’s New in ITR Forms for AY 2026-27

A few changes are worth knowing before you pick a form:

• House property limit raised: ITR-1 and ITR-4 now allow reporting income from up to two house properties, up from one.
• Unrealised rent field added: A new field lets you separately report rent you couldn’t recover from tenants.
• Tenant PAN/TAN disclosure: If TDS was deducted under Section 194-IB, you must report the tenant’s PAN or Aadhaar; under Section 194-I, the tenant’s TAN is required.
• Dual contact details: ITR-1 now accepts both primary and secondary mobile numbers, email addresses, and postal addresses.
• Foreign retirement accounts: Retirement benefit accounts held in notified foreign countries no longer need separate reporting in ITR-1 and ITR-4.
• Section 80A relief moved: Double-taxation relief claims under Section 80A can now only be made through ITR-2 and ITR-3, simplifying ITR-1 and ITR-4.

These changes generally make ITR-1 and ITR-4 usable by more taxpayers than before, so it’s worth re-checking eligibility even if you filed ITR-2 last year.

Old Tax Regime vs New Tax Regime: Why It Affects Your ITR Filing

Your choice of tax regime doesn’t change which ITR form you file, but it does affect what you report within that form, and it’s a decision you need to make before you start filing.

New Tax Regime is the default option for AY 2026-27. Under it, you get lower slab rates but cannot claim most common deductions and exemptions, including HRA, Section 80C (LIC, PPF, ELSS), and home loan interest under Section 24(b) (except for let-out property).

Old Tax Regime has higher slab rates but allows the full range of deductions and exemptions taxpayers are used to claiming.

A few points to keep in mind:

• If you have business or professional income (filing ITR-3 or ITR-4) and want to switch from the new regime back to the old regime, you can typically do so only once this choice has consequences in future years, so plan it carefully.
• Salaried individuals filing ITR-1 or ITR-2 can choose between regimes every year when filing.
• All ITR forms for AY 2026-27 carry a dedicated field to declare your regime choice; this isn’t optional, so get it right before submission.

Why is Filing an ITR Mandatory?

1. Legal requirement: All qualified people who satisfy specific income criteria under the Act must file Income Tax Returns (ITRs).
2. Income reporting: This guarantees the tax agency gets income reports from people by salaries, business income, professional income, investment income, property income, and other means.
3. Refund claims: Should they have overpaid their taxes, taxpayers have the right to request refunds by submitting ITRs.
4. Record maintenance: By filing ITRs, taxpayers may maintain records of their income declarations and tax payments all during the year.
5. Loan and credit applications: Banks and NBFCs routinely ask for ITR acknowledgements before approving credit or loans.
6. Visa and Immigration: Many nations’ embassies and immigration divisions demand that people provide ITRs so they can check their financial stability. It enables people to avoid interest payments, notices, late-filing fines, etc.
7. Future Deals: ITRs provide legitimacy for future transactions, including investments and business opportunities.

Process of Filing an ITR

1. Gathering Required Documents: Form 16 (or Form 130, which now carries TDS details for FY 2025-26), PAN, Aadhaar, bank statements, investment proofs, and Form 26AS/AIS.
2. Choosing an appropriate ITR Form: Choose the correct form as per the type and category of income you have received.
3. Calculate Total Income: Calculate your total taxable income.
4. Availing all Possible Tax Benefits: Include all possible benefits that are allowable as per the rules set by the authorities.
5. Verify Personal Information: Enter all your income, tax, and personal details correctly in the return form.
6. Filing Return: File ITR through the online income tax portal.
7. Completing E-verification Process: Validate your return online within the prescribed period of time.

Due Dates and Consequences of Late Filing (AY 2026-27)

Due dates for AY 2026-27 are now split by form type rather than applying a single date to everyone:

If you miss the due date, here’s what it costs you:

1. Late filing fee (Section 234F): Up to ₹5,000 if your total income exceeds ₹5 lakh; capped at ₹1,000 if income is below ₹5 lakh.
2. Interest on unpaid tax (Section 234A): 1% per month on outstanding tax from the day after the due date until you pay.
3. Loss of carry-forward benefits: Business losses and most capital losses cannot be carried forward if you file after the due date.
4. Delayed refunds: Late filing pushes your refund further back in the processing queue.
5. Notices and scrutiny: Late or inconsistent filings increase the chance of department correspondence, especially with AIS now cross-checking capital gains, dividends, and foreign remittances against your return.
6. Loan and visa friction: Banks and embassies may flag missing or late ITR acknowledgements during verification.
7. Updated returns as a last resort: If you miss even the belated return deadline, an Updated Return (ITR-U) under Section 139(8A) is available for up to 48 months from the end of the assessment year, but it comes with an additional 25% to 70% penalty on the aggregate tax and interest due, so it should never be your first plan.

To avoid these penalties and file with confidence, Kanakkupillai’s tax experts can help you choose the right form, pick the right regime, and file on time every time.

Conclusion

Selecting the correct ITR form is the foundation of accurate tax filing; get it wrong, and even a correctly computed return can be marked defective. With AY 2026-27 bringing expanded eligibility for ITR-1 and ITR-4, split due dates by form type, and tighter AIS-based reconciliation, it’s worth confirming your form and regime choice fresh this year rather than assuming last year’s filing still applies.

Kanakkupillai’s ITR filing professionals help you identify the right ITR form, compare old- and new-regime outcomes, and file accurately so you stay compliant without the back-and-forth.
