ITR Form Selection Guide AY 2026-27: ITR-1 vs 2 vs 3 vs 4

Picking the wrong ITR form is the single most common reason a return gets flagged as defective under Section 139(9) and bounced back by the Centralised Processing Centre (CPC). The seven ITR forms are not interchangeable. Each one is scoped to a specific class of taxpayer and a specific income mix, and crossing even one eligibility line, a single mutual fund redemption, a second source of business income, a directorship held on paper, forces you into a different form.

This guide walks through all seven forms for AY 2026-27 (the assessment year for income earned during FY 2025-26): who each form is for, the exclusions that disqualify you, the changes CBDT notified this year, and a decision tree you can run top-to-bottom to land on the correct form before you open the portal.

How ITR Form Selection Works for AY 2026-27

Form selection is driven by three things, checked in this order:

1. Who you are (taxpayer status). An individual, an HUF, a partnership firm, an LLP, a company, or a trust each starts in a different lane. Companies always file ITR-6 (unless exempt under Section 11). Firms and LLPs file ITR-5. Trusts and political bodies file ITR-7. Individuals and HUFs choose between ITR-1, ITR-2, ITR-3, and ITR-4 based on income mix.
2. What income you earned (income heads). Salary, house property, capital gains, business or professional income, and other sources each carry their own form restrictions. Capital gains and business income are the two heads that most often push a filer up to a more detailed form.
3. Any disqualifying flags. Foreign assets, directorship, unlisted shares, income above Rs 50 lakh, more than the permitted number of house properties, and brought-forward losses each act as a hard gate that overrides the simpler forms.

Run all three. The form you can use is the simplest one that still accommodates every line of your income and every flag that applies to you. When two forms could fit, the rule is to move up, not down: if you have any business or professional income alongside capital gains, ITR-3 covers both, so ITR-2 is wrong.

Quick Decision Table: Which ITR Form Fits Your Income

A Step-by-Step Decision Tree

Work through these questions in sequence. Stop at the first one that lands you on a form.

• Are you a company? Yes, and you do not claim exemption under Section 11: file ITR-6. Yes, but you are registered under Section 11 (Form 12A charitable or religious registration): file ITR-7.
• Are you a partnership firm, LLP, AOP, or BOI? If presumptive taxation applies and you are a firm (not an LLP) with total income up to Rs 50 lakh, ITR-4 is available. Otherwise the entity files ITR-5.
• Are you a trust, charity, political party, or research institution filing under Section 139(4A) to 139(4D)? File ITR-7.
• You are an individual or HUF. Do you have any business or professional income? If yes and it is fully under the presumptive scheme (44AD/44ADA/44AE) with total income up to Rs 50 lakh, consider ITR-4. If yes and you keep regular books or you are a firm partner, file ITR-3.
• No business income. Do you have any capital gains (other than Section 112A LTCG up to Rs 1.25 lakh), more than two house properties, foreign assets or income, a directorship, unlisted shares, or income above Rs 50 lakh? If yes to any, file ITR-2.
• None of the above flags apply, and you are a resident individual with income up to Rs 50 lakh from salary, pension, up to two house properties, and other sources? File ITR-1 (Sahaj).

The two questions that catch the most filers are the capital gains gate (a single equity or debt fund sale moves you off ITR-1 and ITR-4) and the business income gate (a side consulting practice moves you off ITR-2 to ITR-3).

ITR-1 (Sahaj): The Simplest Form

ITR-1 is the most-used return in India and the most tightly scoped. It is built for resident individuals with a clean, salaried-style profile.

Who can file ITR-1

You can use ITR-1 if all of these are true:

• You are a resident individual (not RNOR, not an NRI, not an HUF).
• Your total income is up to Rs 50 lakh for FY 2025-26.
• Your income comes from salary or pension, income from up to two house properties, other sources (savings and FD interest, dividends, family pension), long-term capital gains under Section 112A up to Rs 1.25 lakh, and agricultural income up to Rs 5,000.

The headline change for AY 2026-27 is the two house property limit. ITR-1 was historically restricted to a single house property, which forced anyone with a second flat into ITR-2. From AY 2026-27, two properties (any mix of self-occupied and let-out) keep you in ITR-1, provided every other condition holds. ITR-1 and ITR-3 also carry a new unrealised rent field this year, aligned to Section 25A, so uncollected rent can be recorded directly in the house property section.

Who cannot file ITR-1

Any one of these pushes you to ITR-2 or ITR-3:

• Total income above Rs 50 lakh.
• Capital gains other than Section 112A LTCG up to Rs 1.25 lakh. Short-term capital gains, debt fund gains, property sale gains, and crypto or VDA gains all disqualify ITR-1.
• Director in any company, listed or unlisted.
• Holding of unlisted equity shares at any time during the year.
• TDS deducted under Section 194N (cash withdrawals above Rs 1 crore).
• ESOP tax deferred under Section 17(2) for an eligible startup.
• Foreign assets, foreign income, or signing authority on a foreign account.
• NRI or RNOR residential status.
• HUF status, or any business or professional income.
• More than two house properties, or agricultural income above Rs 5,000.
• Brought-forward losses to set off.

The full eligibility walkthrough sits in the ITR-1 Sahaj filing guide for AY 2026-27. ITR-1 is a non-audit form by definition, so its due date is July 31, 2026.

ITR-2: Capital Gains, Multiple Properties, Foreign Assets

ITR-2 is the form for individuals and HUFs whose profile is richer than ITR-1 allows, but who have no business or professional income. If your only complication is investments, property, or foreign holdings, ITR-2 is where you go.

Who should file ITR-2

File ITR-2 if you have no business income and any of the following applies:

• Capital gains from equity, mutual funds, real estate, bonds, or other capital assets (short-term or long-term, and any amount of Section 112A LTCG above Rs 1.25 lakh).
• More than two house properties.
• Foreign income or foreign assets, including ESOPs in a foreign parent, overseas bank accounts, or foreign mutual funds. Schedule FA disclosure is mandatory for residents even when those assets produce no taxable income.
• Director in any company, or holdings of unlisted equity shares.
• Total income above Rs 50 lakh.
• Agricultural income above Rs 5,000, or income from lottery, horse racing, and other special-rate sources.

For AY 2026-27, ITR-2 carries a dedicated buy-back loss row in Schedule CG. The loss is allowed only if the matching deemed dividend is disclosed under Income from Other Sources, so the two entries must travel together. The pre and post July 23, 2024 capital gains split continues, because LTCG rates and indexation rules changed mid FY 2024-25.

The line filers miss most often is the capital gains gate: any taxable capital gain, regardless of size, takes you off ITR-1 and onto ITR-2. The form-specific detail is in the ITR-2 AY 2026-27 guide. Due date is July 31, 2026 for non-audit filers, and October 31, 2026 in the rare case an audit applies.

ITR-3: Business and Professional Income

ITR-3 is the form for individuals and HUFs who earn business or professional income and do not fully use the presumptive scheme. It is the most schedule-heavy of the individual forms.

Who should file ITR-3

• You run a proprietary business or profession and keep regular books rather than opting for presumptive taxation.
• You are a partner in a firm or LLP drawing remuneration, interest on capital, or a share of profit. The firm files ITR-5; you, as a partner, file ITR-3.
• You have speculative business income, or treat intra-day equity or F&O activity as business income.
• You have business income alongside salary, capital gains, foreign income, or rental income. ITR-3 absorbs all of them in one return.

ITR-3 is the catch-all once business or professional income is in the picture. If you have a side consulting practice on top of a salary, you cannot use ITR-2; the professional income forces ITR-3. The same buy-back loss row and pre/post July 23, 2024 capital gains split that appear in ITR-2 also appear here, and GST-registered filers must report GSTIN-wise turnover so it can be cross-checked against GSTR-1 and GSTR-3B.

Audit triggers to check first

A tax audit under Section 44AB applies if business turnover exceeds Rs 1 crore (raised to Rs 10 crore where 95% or more of receipts and payments are digital), or professional gross receipts exceed Rs 75 lakh, or you declare profit below the presumptive rate while your income exceeds the basic exemption limit. Audit changes your deadline, not your form.

The full breakdown is in the ITR-3 AY 2026-27 guide. Non-audit ITR-3 is due August 31, 2026, a permanent shift under the Finance Act 2026; audit cases file by October 31, 2026, and transfer pricing cases by November 30, 2026.

ITR-4 (Sugam): Presumptive Taxation

ITR-4 is the presumptive form. Its whole purpose is to let small businesses and professionals declare a deemed profit at a fixed rate without maintaining detailed books or filing a balance sheet.

Who can file ITR-4

You can use ITR-4 if all of these hold:

• You are a resident individual, HUF, or partnership firm. LLPs are excluded and file ITR-5.
• Your total income is up to Rs 50 lakh.
• Your business or professional income is declared under one of the presumptive sections:
  • Section 44AD: business turnover up to Rs 3 crore where cash receipts are 5% or less of total receipts (otherwise Rs 2 crore). Deemed profit is 6% of digital turnover and 8% of cash turnover.
  • Section 44ADA: professional gross receipts up to Rs 75 lakh where cash receipts are 5% or less (otherwise Rs 37.5 lakh). Deemed profit is 50% of gross receipts.
  • Section 44AE: goods carriage operators owning up to 10 vehicles at any point in the year.
• Your other income is limited to salary or pension, one house property, and interest or family pension.

Who cannot file ITR-4

• Any capital gains, even Rs 100 of LTCG or STCG. Move to ITR-3 (since you also have business income).
• NRI or RNOR status, directorship, or unlisted equity holdings.
• Foreign assets, foreign income, or signing authority abroad. ITR-4 has no Schedule FA.
• Total income above Rs 50 lakh, or agricultural income above Rs 5,000.
• More than one house property, or brought-forward losses to set off.

Note the operational quirk: presumptive filers pay advance tax in a single instalment by March 15, not in four instalments. The ITR-4 Sugam filing guide covers the deemed-profit computation and the Section 44AD five-year lock-in. Non-audit ITR-4 is due August 31, 2026 under the same Finance Act 2026 change as ITR-3.

ITR-5: Firms, LLPs, AOPs, and BOIs

ITR-5 is the entity-level return for non-corporate, non-individual bodies. It requires a full balance sheet, profit and loss account, and Schedule BP to convert book profit into taxable income.

ITR-5 is mandatory for:

• Registered and unregistered partnership firms.
• Limited Liability Partnerships (LLPs).
• Associations of Persons (AOPs) and Bodies of Individuals (BOIs).
• Artificial juridical persons, investment funds, business trusts, and estates of deceased or insolvent persons.

It cannot be used by individuals or HUFs (ITR-1 to ITR-4), companies (ITR-6), or trusts and bodies exempt under Section 11 (ITR-7). A frequent error is a partner filing ITR-5 for themselves: the firm files ITR-5, while each partner reports remuneration, interest, and profit share on their personal ITR-3. Firms and LLPs are taxed at a flat 30% plus surcharge and cess, with partner remuneration deductible within the Section 40(b) limits. The ITR-5 filing guide for partnership firms, LLPs, and AOPs details Schedule BP and the Section 40(b) computation. Non-audit firms file by July 31, 2026; audit cases by October 31, 2026; transfer pricing cases by November 30, 2026.

ITR-6: Companies

ITR-6 is the return for every company registered under the Companies Act 2013 (or prior company law), with one exception: companies that claim income exemption under Section 11 (charitable or religious bodies holding Form 12A registration) file ITR-7 instead.

Points that define ITR-6:

• It must be filed electronically using a Digital Signature Certificate (DSC). There is no Aadhaar OTP option for companies and no physical filing. If the authorised signatory's DSC has lapsed, the return cannot be filed until it is renewed.
• Every incorporated company must file, including loss-making, zero-turnover, and dormant companies. A company stays a filing entity until it is struck off by the Registrar of Companies.
• A Section 8 (not-for-profit) company files ITR-6 unless it holds valid Form 12A registration, in which case it uses ITR-7.

ITR-6 carries Minimum Alternate Tax under Section 115JB, ICDS adjustments, and Schedule AL for all companies. Because audit is effectively mandatory, the due date is October 31, 2026 (November 30, 2026 where transfer pricing applies). The ITR-6 filing guide for companies covers Schedule BP, MAT, and the DSC workflow.

ITR-7: Trusts, Charities, and Political Parties

ITR-7 is the return for persons and institutions filing under Sections 139(4A), 139(4B), 139(4C), and 139(4D). This covers:

• Charitable and religious trusts and institutions claiming exemption under Sections 11 and 12.
• Political parties under Section 139(4B).
• Research associations, news agencies, and notified institutions under Section 139(4C).
• Universities, colleges, and institutions under Section 139(4D).
• Section 8 companies that hold Form 12A registration.

ITR-7 filers are due October 31, 2026 in audit cases and July 31, 2026 in non-audit cases. The defining test is the registration status, not the legal form: a Section 8 company without Form 12A drops back to ITR-6, while one with valid registration uses ITR-7.

AY 2026-27 Filing Deadlines by Form

The non-audit deadline most filers know is July 31, 2026, and audit cases run to October 31, 2026. The one nuance for AY 2026-27 is that ITR-3 and ITR-4 non-audit cases now have a permanent August 31 date under the Finance Act 2026. The full picture:

Filing on time preserves your loss carry-forward rights, keeps the regime choice open for that year, and removes exposure to the Section 234F late filing fee (Rs 1,000 if income is up to Rs 5 lakh, Rs 5,000 otherwise) and Section 234A interest. The complete deadline reference is in the ITR filing last date AY 2026-27 guide.

Common Form Selection Mistakes That Trigger a Defective Return Notice

These are the selection errors CPC catches most often, each leading to a defective return notice under Section 139(9):

• Filing ITR-1 with capital gains. Any equity, debt fund, or property sale (beyond Section 112A LTCG up to Rs 1.25 lakh) invalidates ITR-1. Use ITR-2, or ITR-3 if you also have business income.
• Filing ITR-1 or ITR-4 as a company director. A directorship, even nominal and unpaid, blocks both forms. The minimum is ITR-2.
• Filing ITR-2 when professional income exists. Freelance or consulting income is professional income and requires ITR-3. ITR-2 is for investment-type income only.
• Filing ITR-4 with foreign income or assets. ITR-4 has no Schedule FA. A single overseas brokerage holding (US stocks via a Vested or IndMoney account) forces ITR-2 or ITR-3.
• Filing ITR-4 above the presumptive ceiling. Turnover above Rs 3 crore (business) or receipts above Rs 75 lakh (profession) pushes you to ITR-3 with regular books.
• A partner filing ITR-5 personally. The firm files ITR-5; the partner files ITR-3 for remuneration, interest, and profit share.
• A dormant or loss-making company skipping ITR-6. Zero turnover does not remove the filing obligation while the company remains incorporated.
• Treating two house properties as an ITR-2 trigger. From AY 2026-27, two properties are allowed in ITR-1, so check whether the simpler form now fits before defaulting to ITR-2.

What Happens If You File the Wrong Form

When CPC processes a return filed on the wrong form, it issues a defective return notice under Section 139(9) with a window (commonly 15 days) to file a corrected return. Miss that window and the original return can be treated as invalid, which means the return is regarded as never filed: you lose loss carry-forward rights, your refund stalls, and if the corrected return crosses the original due date you face the Section 234F fee and Section 234A interest. The fix is always to confirm the form before filing, not after the notice arrives.

The which ITR form to file for AY 2026-27 overview summarises the same selection logic with this year's changes side by side.
