ITR Form Selection Guide for AY 2026-27: Which Form to File Under the New Income Tax Act 2025

Choosing the wrong ITR form is one of the most common and costly mistakes a taxpayer can make during income tax filing. Filing your income tax return on an incorrect form makes the return defective. The Income Tax Department sends a defective return notice under the applicable provision, and if the taxpayer does not rectify it within the specified period, the return is treated as if it was never filed. That means losing deductions, losing refunds, and potentially attracting penalties.

For Assessment Year 2026-27, the stakes are higher than in previous years. The Income Tax Act 2025 came into force on April 1, 2026, replacing the Income Tax Act 1961. This structural overhaul has introduced new terminology, restructured section references, and updated the schedules embedded inside each income tax return form. While the broad categories of ITR forms - from ITR-1 to ITR-7 - continue to exist, the conditions for eligibility, the schedules within each form, and the way income and deductions are reported have all been updated to align with the new Act.

This guide walks through every ITR form applicable for AY 2026-27, explains who must use each one, who is excluded from each, and helps taxpayers and CA firms make the correct selection from the very start of the itr filing process.

Why ITR Form Selection Matters More in AY 2026-27

Every assessment year brings some degree of change to ITR forms - updated schedules, new disclosure requirements, or revised instructions. But AY 2026-27 is structurally different because it is the first filing season under an entirely new piece of legislation.

The Income Tax Act 2025 reorganised the entire framework of taxation. Concepts that were spread across hundreds of sections in the 1961 Act have been consolidated and renumbered. The Act also introduced cleaner terminology - for instance, the concept of a unified "Tax Year" replacing the older "Previous Year" and "Assessment Year" distinction in the legislative text, even though the filing cycle continues to reference AY 2026-27 for practical purposes.

ITR forms for AY 2026-27 have been updated to reference the new section numbers from the Income Tax Act 2025. Schedules for capital gains, foreign income, deductions, and tax computation now carry revised references. Taxpayers and CA firms using outdated form versions or filing software that has not been updated will encounter validation errors when uploading the return on the income tax portal.

Additionally, the default tax regime under the Income Tax Act 2025 is the new regime. Every taxpayer must make a conscious, explicit choice at the time of filing - and the ITR form selected must support the correct regime computation. This makes form selection and regime selection two interconnected decisions that must be made together before filing begins.

Overview of ITR Forms for AY 2026-27

There are seven ITR forms applicable for different categories of taxpayers for AY 2026-27. Here is a quick reference before we go into the detailed eligibility conditions for each.

ITR-1 (Sahaj) - For Simple Salaried Taxpayers

ITR-1, popularly known as Sahaj, is the simplest ITR form and is designed for resident individual taxpayers with straightforward income profiles. For AY 2026-27, ITR-1 can be used by a resident individual whose total income does not exceed Rs. 50 lakh during the financial year FY 2025-26, and whose income comes from the following sources only:

• Salary or pension income
• Income from one house property (excluding cases where loss is carried forward from previous years)
• Income from other sources such as interest from savings accounts, fixed deposits, or family pension - but not from lottery, horse races, or speculative sources
• Agricultural income up to Rs. 5,000

Who Cannot Use ITR-1 for AY 2026-27

Even if total income is below Rs. 50 lakh, a taxpayer cannot use ITR-1 if any of the following conditions apply:

• The taxpayer is a non-resident or not ordinarily resident in India
• The taxpayer is a director in any company
• The taxpayer holds unlisted equity shares at any time during the year
• The taxpayer has income from capital gains - short-term or long-term - on any asset
• The taxpayer has income from more than one house property
• The taxpayer has foreign assets or income from foreign sources
• The taxpayer has brought forward losses to be set off in AY 2026-27
• Tax has been deducted under provisions applicable to non-residents
• The taxpayer has deposited more than Rs. 1 crore in a current account, paid electricity bills above Rs. 1 lakh, or incurred foreign travel expenses above Rs. 2 lakh - these are high-value transaction disclosures that mandate a more detailed form

ITR-1 is the most heavily pre-filled form on the income tax e filing portal. Salary data from Form 16, TDS credits from Form 26AS, and interest income from banks are automatically populated. However, taxpayers must verify this data carefully before submitting - particularly for AY 2026-27 where the pre-filled data is sourced from systems now aligned with Income Tax Act 2025 section codes.

ITR-2 - For Individuals and HUFs with Capital Gains or Multiple Income Sources

ITR-2 is for individuals and Hindu Undivided Families who have income from sources that go beyond ITR-1's scope, but who do not have any income from business or profession. ITR-2 is the correct income tax return form for the following taxpayer profiles:

• Taxpayers with capital gains income - from sale of property, mutual funds, shares, or any other capital asset
• Taxpayers with income from more than one house property
• Non-residents or not-ordinarily-resident individuals
• Taxpayers who are directors in a company
• Taxpayers holding unlisted equity shares
• Taxpayers with foreign assets or foreign income
• Taxpayers with total income exceeding Rs. 50 lakh (if no business income)
• Taxpayers with brought-forward losses from capital gains to be set off

ITR-2 is significantly more detailed than ITR-1. It includes dedicated schedules for capital gains computation - broken into short-term and long-term categories - as well as schedules for foreign assets and foreign income disclosure, which are now mandatory under the updated FEMA and income tax compliance framework.

For AY 2026-27, taxpayers filing ITR-2 must ensure that the capital gains schedules reference the correct provisions of the Income Tax Act 2025, particularly for transactions such as the sale of property or redemption of mutual fund units where the holding period and tax rate calculations have specific section references in the new Act.

ITR-3 - For Individuals and HUFs with Business or Profession Income

ITR-3 is the ITR form for individuals and HUFs who earn income from a proprietary business or from a profession - including doctors, lawyers, consultants, architects, freelancers, and any individual running a business in their own name or as part of a partnership.

ITR-3 must be used when:

• The taxpayer has income under the head "Profits and Gains of Business or Profession"
• The taxpayer is a partner in a partnership firm and receiving salary, interest, or share of profit from the firm
• The taxpayer has business income along with salary, capital gains, house property, or other income
• The taxpayer is opting out of the presumptive taxation scheme after having opted in for five consecutive years

ITR-3 is the most comprehensive form for individual filers. It includes a full profit and loss account and balance sheet requirement for businesses with turnover above specified thresholds, as well as schedules for depreciation, partner details, quantitative details of traded goods, and more. For AY 2026-27, the financial statements and computation schedules within ITR-3 follow the updated provisions of the Income Tax Act 2025 relating to business income, disallowances, and deductions.

ITR-4 (Sugam) - For Presumptive Taxation Scheme Taxpayers

ITR-4, also called Sugam, is designed for individuals, HUFs, and firms (other than LLPs) who have opted for the presumptive taxation scheme under the relevant provisions of the Income Tax Act 2025. The presumptive scheme allows eligible taxpayers to declare income at a flat percentage of turnover or gross receipts without maintaining detailed books of accounts.

ITR-4 is applicable when:

• The taxpayer is a resident individual, HUF, or firm (not LLP) with business turnover up to Rs. 3 crore under the business presumptive scheme, where digital receipts account for at least the required proportion
• The taxpayer is a professional with gross receipts up to Rs. 75 lakh under the professional presumptive scheme
• The taxpayer also has salary income, income from one house property, or income from other sources alongside the presumptive business or profession income
• Total income does not exceed Rs. 50 lakh

Who Cannot Use ITR-4

• Non-residents and not-ordinarily-resident individuals
• Taxpayers who are directors in a company
• Taxpayers holding unlisted equity shares
• Taxpayers with capital gains income
• Taxpayers with foreign assets or foreign income
• LLPs - they must use ITR-5
• Taxpayers whose business turnover or professional receipts exceed the presumptive scheme threshold

An important point for AY 2026-27: if a taxpayer has been using the presumptive scheme for the past five consecutive years but wishes to opt out this year, they must file ITR-3 and will be required to maintain books of accounts and get them audited if income exceeds the basic audit threshold. This decision must be made before filing and cannot be reversed mid-way.

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

ITR-5 is for entities other than individuals, HUFs, and companies. This form is used by:

• Partnership firms (registered or unregistered)
• Limited Liability Partnerships (LLPs)
• Association of Persons (AOPs)
• Body of Individuals (BOIs)
• Artificial juridical persons
• Cooperative societies
• Local authorities

ITR-5 requires a full set of financial statements including the profit and loss account, balance sheet, and audit information where applicable. For LLPs, partner details, contribution details, and remuneration paid to designated partners must also be disclosed.

For AY 2026-27, firms and LLPs filing ITR-5 must ensure that all income head references and deduction claims use the updated provisions of the Income Tax Act 2025. This is especially relevant for firms that claim deductions on partner remuneration and interest, as the section governing these deductions has been renumbered in the new Act.

ITR-6 - For Companies

ITR-6 is mandatory for all companies registered under the Companies Act 2013 or earlier Acts, except those that claim exemption under the provisions applicable to charitable or religious trusts under the Income Tax Act 2025.

Companies filing ITR-6 must include:

• Complete audited financial statements
• Schedule AL (Asset and Liability disclosure)
• Details of shareholding and changes during the year
• Related party transactions
• ICDS (Income Computation and Disclosure Standards) adjustments
• Minimum Alternate Tax (MAT) computation where applicable
• Country-by-country reporting details for multinational groups where applicable

Companies that claim deduction under the relevant provisions of the Income Tax Act 2025 for charitable activities and file under those provisions must use ITR-7 instead of ITR-6.

ITR-7 - For Trusts, Political Parties, and Exempt Institutions

ITR-7 is filed by persons - including companies - that are required to file their income tax return under specific provisions applicable to charitable or religious trusts, political parties, scientific research institutions, universities, and similar exempt entities under the Income Tax Act 2025.

This includes registered public charitable trusts, educational institutions, hospitals, religious trusts, electoral trusts, political parties, and mutual benefit funds. The filing requirements for ITR-7 are detailed and include schedules for income application, accumulation of income, foreign contributions, and compliance with registration conditions under the Income Tax Act 2025.

How to Choose the Right ITR Form: A Step-by-Step Decision Framework

For most individual taxpayers, the form selection decision can be made by working through the following questions in order. This framework is particularly useful for CA firms managing a large client base during the AY 2026-27 itr filing season.

Step 1: Identify the Taxpayer Category

Is the taxpayer an individual, HUF, firm, LLP, company, or trust? Companies always file ITR-6 or ITR-7. LLPs always file ITR-5. Trusts and exempt institutions file ITR-7. For individuals and HUFs, proceed to Step 2.

Step 2: Check for Business or Profession Income

Does the individual or HUF have any income from business or profession? If yes, check whether presumptive taxation applies. If presumptive taxation is applicable and opted for, use ITR-4. If the taxpayer has regular business income outside the presumptive scheme, use ITR-3. If there is no business or profession income, proceed to Step 3.

Step 3: Check for Capital Gains, Foreign Assets, or Directorship

Does the individual have capital gains income, foreign assets, foreign income, a directorship in any company, or unlisted equity shares? If yes, use ITR-2 regardless of income level. If none of these apply, proceed to Step 4.

Step 4: Apply the ITR-1 Eligibility Test

Is the taxpayer a resident individual with income only from salary, one house property, and other sources, with total income below Rs. 50 lakh? If all conditions are met, ITR-1 is the correct form. If any condition is not met, use ITR-2.

Key Changes Under Income Tax Act 2025 That Affect ITR Form Filing

Beyond form selection, taxpayers and CA firms must be aware of how the Income Tax Act 2025 has changed the internal structure of each ITR form for AY 2026-27.

New Section Numbers Across All Schedules

Every schedule within every ITR form now references sections from the Income Tax Act 2025. The schedule for Chapter VI-A deductions, the schedule for exempt income, the capital gains schedules, and the tax computation statement all carry new section numbers. Using an outdated reference or filing software that has not been updated will result in schema validation errors when uploading the return on the income tax e filing portal.

Tax Regime Selection Is Now a Mandatory Declaration

Every ITR form for AY 2026-27 requires an explicit declaration of whether the taxpayer is opting for the new tax regime (default) or the old tax regime (opt-in). This selection changes the entire computation - which exemptions are available, which deductions are allowed, and how the tax liability is calculated. Once filed and verified, regime selection cannot be changed after the original filing deadline in most circumstances. This decision must be made carefully before the income tax return is submitted.

Revised Schedules for Capital Gains

The Union Budget 2024 revised the capital gains tax structure - changing holding period thresholds, tax rates for certain assets, and the indexation benefit availability. ITR forms for AY 2026-27 incorporate these revisions fully. Taxpayers with capital gains from property, equity, mutual funds, or bonds must use the updated schedules in ITR-2 or ITR-3 as applicable, ensuring the correct asset type, holding period, and applicable rate are selected from the new provisions of the Income Tax Act 2025.

Mandatory Disclosure of High-Value Transactions

The threshold-based disclosure requirements for cash deposits, electricity bills, and foreign travel expenses - which already existed - have been retained and recodified under the Income Tax Act 2025. Taxpayers who exceed these thresholds cannot use the simplified ITR-1 form and must move to ITR-2 or ITR-3, where these disclosures can be made in the appropriate schedule.

Common Mistakes in ITR Form Selection for AY 2026-27

Even experienced filers make form selection errors every year. For AY 2026-27, these are the mistakes most likely to occur during the first filing season under the Income Tax Act 2025.

Filing ITR-1 When Capital Gains Exist

This is the single most common form selection error for salaried taxpayers. Many individuals who are primarily salaried also redeem mutual fund units, receive equity dividends, or sell property during the year. Any capital gains transaction - even a small redemption - disqualifies the taxpayer from using ITR-1. Such taxpayers must use ITR-2.

Using ITR-4 When Presumptive Turnover Threshold Is Exceeded

If a business that has been filing ITR-4 under the presumptive scheme crosses the turnover threshold during FY 2025-26, they are no longer eligible for the scheme and must file ITR-3 for AY 2026-27 with complete books of account. Continuing to file ITR-4 beyond the threshold limit is a defective return.

Partners Filing ITR-1 or ITR-2 Instead of ITR-3

Individuals who are partners in a firm - whether active partners or sleeping partners - receive income in the form of salary, interest, and profit share from the firm. This income falls under "Profits and Gains of Business or Profession" and requires ITR-3, not ITR-1 or ITR-2, regardless of how small the partnership income is.

Not Updating to the AY 2026-27 Form Version

Every year, the Income Tax Department notifies the updated ITR forms for the new assessment year. For AY 2026-27, the forms are updated to align with the Income Tax Act 2025. Filing on an outdated form version from AY 2025-26 will be rejected by the portal's validation system. Always ensure you are using the forms notified for AY 2026-27 specifically when you file income tax return online for this year.

How Income Tax Filing Software Simplifies Form Selection

For CA firms managing hundreds of clients during the AY 2026-27 income tax itr filing season, manual form selection for each client is time-consuming and prone to oversight. A reliable income tax software simplifies this process by automatically mapping the taxpayer's income profile to the correct ITR form based on data entered - flagging eligibility conditions, prompting for mandatory disclosures, and ensuring that the form version used is the one notified for AY 2026-27 under the Income Tax Act 2025.

Beyond form selection, good income tax software also validates the return against the Income Tax Department's schema before upload, catches errors in section references, ensures the tax regime selection is consistent throughout the computation, and generates the final XML or JSON file required for submission on the income tax portal. For a filing season as structurally significant as AY 2026-27, using updated and validated software is not a convenience - it is a compliance requirement.

ITR Filing Deadline for AY 2026-27

The key deadlines for income tax filing for AY 2026-27 are:

The July 31 deadline for non-audit cases is the critical date for the majority of individual taxpayers. Filing before this date ensures refunds are processed faster, avoids the late filing fee, and keeps the taxpayer's compliance record clean for AY 2026-27.
