Income Tax Return Filing in India: Complete Guide to ITR-1 to ITR-7

Choosing the correct income tax return (ITR) form is the first step in filing accurately. A salaried person may need ITR-2 instead of ITR-1; a self-employed person may need ITR-3 instead of ITR-4. The answer depends on the taxpayer, every source of income and the form’s eligibility rules.

This guide covers income earned in FY 2025–26 and reported in Assessment Year (AY) 2026–27. Select AY 2026–27 on the e-filing portal for that income.

What Is Income Tax Return Filing?

Income tax return filing is the process of reporting your income, eligible deductions, taxes paid and any refund due to the Income Tax Department. An ITR brings together income such as salary, business profits, house-property income, capital gains and interest, where applicable.

Tax deducted at source (TDS) does not replace your return. You may still be required to file and filing may be necessary to claim a refund. Whether a return is compulsory depends on the applicable income limits and other legal conditions, so do not decide solely by looking at the tax deducted from your salary.

Which ITR Form Should You File?

First identify who is filing, then check the income sources. Use this table as a starting point; the detailed eligibility conditions should be checked against the official ITR forms and utilities provided by the Income Tax Department.

For example, an LLP generally files ITR-5 even if it is a small business. A sole proprietor, on the other hand, reports business income in an individual return, usually ITR-3 or, if eligible, ITR-4.

ITR-1 to ITR-7: Key Differences

Who Can File ITR-1?

File ITR-1 (Sahaj) form can be filed by an eligible resident individual with total income up to ₹50 lakh from the permitted sources. These include the salary or pension, eligible house-property income and various specified other sources such as interest. For AY 2026–27, the department’s guidance permits income from up to two house properties, agricultural income up to ₹5,000 and eligible long-term capital gains under Section 112A up to ₹1.25 lakh.

ITR-1 has exclusions. It generally cannot be used by a company director, someone who held unlisted equity shares during the year or someone with foreign assets or foreign-source income. Short-term capital gains and a loss that must be carried forward can also rule it out. Non-resident and resident but not ordinarily resident individuals should check the applicable detailed form.

Who Can File ITR-2?

ITR-2 is for an individual or Hindu Undivided Family (HUF) without income chargeable as profits and gains of business or profession who cannot use ITR-1. Taxpayers who meet these conditions can file ITR2 form for reporting applicable income and other required details. It may suit someone reporting capital gains outside ITR-1’s limited allowance, foreign assets or income or other details the simplified form cannot accommodate. A non-resident individual without business or professional income may also need ITR-2.  

If you have business or professional income, examine ITR-3 instead.

Who Can File ITR-3?

ITR-3 form filing online generally applies to individuals and HUFs with business or professional income who are not eligible for ITR-4. This may include a proprietor reporting business results through regular accounts or a professional whose income and other circumstances do not meet ITR-4’s conditions.  ITR-3 generally applies to individuals and HUFs with business or professional income who are not eligible for ITR-4. This may include a proprietor reporting business results through regular accounts or a professional whose income and other circumstances do not meet ITR-4’s conditions.

ITR-3 can also report relevant income under other heads, such as salary, house property and capital gains. Having a salary alongside business income does not, by itself, make ITR-1 or ITR-2 suitable.

Who Can File ITR-4?

ITR-4 (Sugam) Form is an optional simplified form for an eligible resident individual, resident HUF or resident partnership firm other than an LLP declaring business or professional income on a presumptive basis under Section 44AD, 44ADA or 44AE.

For the AY 2026–27, its conditions include the total income not exceeding ₹50 lakh. The form also permits the certain other income, including the eligible income from up to two house properties and Section 112A long-term capital gains up to ₹1.25 lakh.

Presumptive taxation alone does not guarantee ITR-4 eligibility. A non-resident, company director, holder of unlisted equity shares or a person with short-term capital gains, for example, cannot use it. Check the full list of exclusions before filing.

Who Is Required to File ITR-5?

ITR-5 is generally the form for LLPs and partnership firms, as well as specified associations of persons, bodies of individuals, cooperative societies, local authorities and other eligible entities. An eligible resident partnership firm may choose ITR-4 if it satisfies that form’s conditions, but an LLP cannot file ITR-4.

Some trusts may use ITR-5. Their correct form depends on the provision under which they must file; the word “trust” alone does not determine the answer.

Who Is Required to File ITR-6?

ITR-6 applies to companies other than those claiming exemption under Section 11. A company files its own return, separate from any personal returns filed by its shareholders or directors. Companies required to file under the specified provisions covered by ITR-7 should assess that form instead.

Who Is Required to File ITR-7?

ITR-7 applies to persons, including companies, required to furnish returns under Sections 139(4A), 139(4B), 139(4C) or 139(4D). These provisions cover categories such as certain charitable or religious trusts, political parties, specified institutions and certain universities or colleges.

It is therefore incorrect to assume that every NGO files ITR-7. The entity’s legal status and the provision creating its filing obligation must be checked.

Documents Required for Income Tax Return Filing

Keep the documents relevant to your income and claims ready before opening the form: –

• Identity and account details: PAN, contact details and bank-account information.
• Salary and TDS records: Form 16, applicable TDS certificates and Form 26AS. Businesses and other deductors should also maintain the relevant records required for TDS Return Filing. 
• Income records: Bank interest statements, rental details, capital-gain statements and records of other income.
• Tax information: Annual Information Statement (AIS), advance-tax and self-assessment-tax payment details.
• Claims and business records: Documents supporting applicable deductions, business accounts, presumptive-income figures and audit details, where required.

AIS and Form 26AS are checking tools, not substitutes for your own records. Compare the reported transactions and tax credits with your documents, then investigate material differences before filing.

How to File an Income Tax Return Online

1. Sign in to the official Income Tax e-Filing portal.
2. Select AY 2026–27 for the income earned during the FY 2025–26.
3. Choose the appropriate ITR form after checking your taxpayer category, residential status, income and the exclusions.
4. Review pre-filled information against the AIS, Form 26AS, certificates and your own records.
5. Complete the remaining schedules for the income, deductions, losses, tax payments and the bank details, as applicable.
6. Review the tax computation, pay any balance tax and submit the return.
7. Save the acknowledgement and verify the return.

Check the tax-regime choice before submission. For an individual with business income who wants to opt for the old regime, Form 10-IEA may need to be filed before the applicable return due date.

Income Tax Return Filing Due Dates

The AY 2026–27 due date basically depends on the filing category. The department’s guidance refers to the 31 July or 31 August 2026 for applicable non-audit cases, 31 October 2026 for relevant audit cases and 30 November 2026 for relevant transfer-pricing cases. Check and verify the date applicable to your return and any official extension; do not assume that every taxpayer has the same deadline. As of September 2026, the ordinary July and August dates have passed.

If you missed or skipped your due date, you can usually file an AY 2026–27 belated return by 31 December 2026 or before the assessment is completed, whichever is earlier. A fee under the Section 234F may apply: ₹1,000 if total income does not exceed the ₹5 lakh and ₹5,000 otherwise. Interest and restrictions on carrying forward certain losses may also be relevant.

How to Verify Your Income Tax Return After Filing

After submitting an ITR, you must complete a separate verification step. You can use an available electronic method or submit the ITR-V as permitted by the official portal. The general time limit for the e-verification or submission of ITR-V is 30 days from the filing. Save the acknowledgement and confirm that the return’s status shows it has been verified.

Common Mistakes to Avoid While Filing ITR

• Choosing a form based only on salary: Capital gains, foreign assets, directorship or business income may change the form.
• Selecting the wrong year: FY 2025–26 income belongs in AY 2026–27.
• Accepting pre-filled figures without checking: Reconcile the AIS, Form 26AS and certificates with your own records.
• Missing an income source: Include applicable interest, rent, gains and business income.
• Claiming unsupported deductions or tax credits: Keep all the required records and check the relevant eligibility conditions.
• Forgetting verification: Confirm it within the prescribed time after the filing.

A final review of the completed return is especially useful when your income sources changed during the year.

What Happens After Filing an Income Tax Return?

After the return is submitted and verified, you can easily track its status on the e-filing portal. The department processes the return and may issue an intimation showing whether its computation matches yours, whether a refund is due or whether a demand has arisen. Review any communication against the return and your records before responding. If the Income Tax Department issues a notice requiring clarification or supporting information, an Income Tax Notice Reply should be prepared based on the specific communication and the relevant records. 

Found an error yourself? An AY 2026–27 return may usually be revised before the 31 March 2027 or completion of the assessment, whichever is earlier, subject to the applicable conditions. Keep the acknowledgement and relevant records so you can review a refund, demand or correction if needed.
