ITR-1 vs ITR-4: Differences, Eligibility and Filing Process for AY 2026–27

The correct filing of an Income Tax Return (ITR) is a critical aspect of financial management. Each year, many taxpayers inadvertently select an incorrect ITR form because they are unaware of the differences. This is especially true for those taxpayers who have difficulty deciding which of the two simplified forms they should choose between ITR-1 vs ITR-4.

Both the ITR-1 and ITR-4 forms are intended to streamline the tax return filing process; however, they are designed for different types of taxpayers. This article provides a comprehensive overview of the differences, eligibility requirements, and processes for filing both ITR Forms.

What is ITR-1 (Sahaj ITR)?

ITR-1, or Sahaj ITR, is a simplified form for individuals residing in India with relatively simple income sources. The focus of this form is to ease tax compliance for salaried taxpayers who receive fixed salaries. The purpose of this form is to allow people to easily fill out their tax forms. A majority of employees in India file their tax returns using Sahaj ITR.

Who is Eligible to File ITR-1?

If you are a resident Indian citizen and your total annual income for AY 2026–27 is ₹50 Lakh or less, you may file ITR-1. Income eligible to be reported on ITR-1 must come from one of the following sources:

1. Income from salary or pension
2. Income from one house property
3. Income from other sources, such as interest from bank deposits

Note: ITR-4 applies only to income declared under presumptive taxation schemes with turnover limits of ₹3 Crore for business (44AD) and ₹75 Lakh for professions (44ADA).

Who Cannot File ITR-1?

Sahaj ITR is a simple form; however, there are limitations on who qualifies to use it. You cannot file an ITR-1 if you:

• Earn income from a business or profession.
• Have capital gains.
• Have more than one house property.
• Are a director of a company.
• Hold unlisted equity shares.

If you do file for ITR-1 under any of those conditions, your return will be considered defective or invalid.

What is ITR-4 (Sugam ITR)?

The Sugam ITR (ITR-4) is specifically for individuals, Hindu Undivided Families (HUF), and firms under the presumptive taxation scheme for the previous year. The Sugam ITR provides a simple tax compliance solution for businesses and freelancers, allowing you to declare your income based on your gross turnover.  It simplifies the filing process and eliminates the need to maintain detailed accounts for small businesses, making it a streamlined option.

Who is Eligible to File ITR-4?

Taxpayers eligible to file ITR-4 for the Assessment Year 2026-27 must meet the following criteria:

• The Taxpayer is a Resident Individual, HUF, or Firm
• Income is declared under Sections 44AD, 44ADA, or 44AE
• The taxpayers' Total Income does not exceed ₹ 75,00,000
• The taxpayers' Business Turnover or Professional Receipts do not exceed the prescribed limits

The ITR-4 is used by Traders, Shopkeepers, Freelancers and Small Professionals.

Who Cannot File ITR-4?

The Sugam Income Tax Return (ITR) cannot be filed by taxpayers who are:

•  Non-resident individuals (NRI).
•  Earning capital gains.
•  Receiving rent from multiple properties.
•  Maintenance of foreign assets or income.
•  Company directors.

Taxpayers with these characteristics will need to apply for an alternate ITR based on their income source.

ITR-1 vs ITR-4: Key Differences

Here’s a quick comparison to help you understand the key differences between ITR-1 and ITR-4:

How to Choose Between ITR-1 and ITR-4

Selecting the correct return form depends on the nature and source of income.

Factors to Consider Before Selecting the ITR Form

In determining which ITR form to complete, you must carefully review your income sources and eligibility requirements. 

• Nature of Income Earned During the Year: A taxpayer who has earned only salary and interest income would qualify for ITR-1. A taxpayer who earns income from a business or professional services would need to review ITR-4 or another form.
• Presumptive Option: ITR-4 can be used only by taxpayers who declare their income under the Presumptive Taxation Scheme. A taxpayer who keeps regular books of accounts cannot utilise the Sugam ITR form.
• Total Income: Both ITR-1 and ITR-4 limit total income to ₹75 Lakh. If a taxpayer's total income exceeds this cap, a different return form must be filed.
• Tax Calculator: A tax calculator will aid you in verifying your income classifications and determining your tax liability before submitting your ITR. This will reduce the risk of you filing the wrong ITR form and facilitate a quicker, smoother process.
