Educational information • Last reviewed September 2026
What is an Income Tax Return?
An Income Tax Return is a prescribed return through which a taxpayer reports relevant income, deductions, tax liability and other required information to the Income Tax Department.
Depending on the taxpayer and the nature of income, an ITR may include information relating to salary, business or professional income, house property, capital gains, interest, dividends and other sources.
Who may need to file an ITR?
Whether a person needs to file an Income Tax Return depends on the applicable provisions of income-tax law and the taxpayer's circumstances.
Filing requirements can depend on factors such as total income, sources of income, residential status, business or professional activity and other conditions specified under the law.
Important
The requirement to file should be determined using the rules applicable to the relevant assessment year and the taxpayer's individual circumstances.
Understanding the Assessment Year
The Assessment Year (AY) is the year in which income from the relevant previous period is assessed and the corresponding return is filed.
For example, income earned during FY 2025–26 is reported for AY 2026–27. The Income Tax Department states that the return for income earned during FY 2025–26 is filed for AY 2026–27 under the Income-tax Act, 1961.
Taxpayers should therefore select the correct assessment year when preparing their return.
Choosing the right ITR form
Different ITR forms apply to different categories of taxpayers and income situations. The appropriate form depends on factors such as residential status, income sources and whether the taxpayer has business or professional income.
ITR-1
For qualifying resident individuals meeting the applicable conditions. For AY 2026–27, the Income Tax Department lists conditions including total income up to ₹50 lakh and specified income sources. Additional exclusions and conditions apply.
ITR-2
Generally applicable to individuals and HUFs who do not have income from profits and gains of business or profession and who are not eligible to use ITR-1.
ITR-3
Generally applicable to individuals and HUFs having business or professional income, subject to the applicable conditions.
ITR-4
Applicable in specified cases involving presumptive taxation and qualifying individuals, HUFs and firms other than LLPs, subject to the conditions prescribed for the relevant assessment year.
The above is only a general overview. The Income Tax Department publishes detailed conditions and exclusions for each form, so the appropriate form should be checked before filing.
Documents commonly needed
The documents required depend on the taxpayer's income and circumstances. Commonly relevant records may include:
PAN and Aadhaar details, where applicable.
Form 16 for salary income.
Bank statements and interest information.
Form 26AS and information available through the income-tax portal.
Annual Information Statement (AIS), where relevant.
Details of investments, capital gains or other income.
Documents supporting eligible deductions or claims.
Business or professional income and expense records, where applicable.
Details of tax deducted or tax already paid.
Step 1: Collect your income information
Start by identifying all relevant sources of income for the financial year. Depending on the taxpayer, this may include salary, pension, interest, dividends, rental income, capital gains, business income or professional receipts.
Reviewing the information available in the tax department's records can help identify discrepancies before the return is submitted.
Step 2: Check deductions and tax details
Review the deductions, exemptions and other tax-related claims that may be applicable to your circumstances.
Supporting documents should be retained even where they are not uploaded with the return, because they may be relevant for future verification or queries.
Step 3: Select the applicable ITR form
Select the assessment year and determine which ITR form applies based on your income sources and circumstances.
Selecting a form simply because it appears shorter or easier is not a reliable approach. The eligibility conditions for the form should be checked first.
Step 4: Prepare and submit the return
The Income Tax Department provides online and utility-based filing options for applicable returns. Enter the required information carefully, review the tax computation and submit the return using the applicable process.
Before submission, review personal information, income, deductions, tax credits, bank details and other relevant fields for consistency.
Step 5: E-verify the return
Filing the return is not the end of the process. The return must be verified through an accepted verification method.
The Income Tax Department currently states that the time limit for e-verification or submission of ITR-V is 30 days from the date of filing the return.
Common verification options
- Aadhaar-based OTP, where eligible.
- EVC through eligible pre-validated accounts.
- Net banking, where available.
- Digital Signature Certificate, where applicable.
- Physical ITR-V submission where permitted.
Common mistakes to avoid
Selecting the wrong assessment year.
Choosing an ITR form that does not match the taxpayer's circumstances.
Leaving out a source of income.
Not checking Form 26AS or AIS information.
Entering incorrect bank-account details.
Claiming deductions without checking eligibility or retaining supporting records.
Forgetting to complete e-verification after filing.
Ignoring notices or communications from the Income Tax Department.
What happens after filing?
After the return is successfully submitted and verified, the Income Tax Department processes it according to the applicable procedures.
Depending on the return, processing may result in a refund, additional tax payable, an intimation or another communication from the department.
Taxpayers should keep the acknowledgement and supporting records safely for their records.
Frequently asked questions
What is the difference between FY and AY?
The financial year is the period in which income is earned, while the assessment year is the year in which that income is assessed and the corresponding return is filed.
Which ITR form should I use?
It depends on your residential status, income sources, business or professional activity and other applicable conditions. The Income Tax Department's current guidance should be checked for the relevant assessment year.

A filed return needs to be verified through an accepted method. The current e-filing guidance provides a 30-day period for e-verification or submission of ITR-V.
