Introduction
Income Tax Return filing for Assessment Year 2026-27 has started, and one of the most common questions taxpayers ask is: “Is ITR filing mandatory for me if my tax is zero?” The answer depends on income level, transaction value, TDS/TCS, foreign assets and taxpayer category.
Many individuals assume that if no tax is payable because of rebate, they do not need to file an ITR. This is incorrect. The requirement to file an income tax return is linked primarily to total income and specific mandatory filing conditions, not only to final tax payable.
For AY 2026-27, taxpayers should check their income, high-value transactions, foreign investments and reporting obligations before deciding whether ITR filing is required.
Basic Rule for Mandatory ITR Filing
The main rule is that a person must file an ITR if total income exceeds the maximum amount not chargeable to tax. The relevant statutory language under Section 139 provides:
“Every person, if his total income or the total income of any other person in respect of which he is assessable under this Act during the previous year exceeded the maximum amount which is not chargeable to income-tax, shall, on or before the due date, furnish a return”
This means the taxpayer should first check total income. The focus is not on whether the final tax payable is nil after rebate.
For example, under the new tax regime, many resident individuals may get rebate benefit where taxable income is within the prescribed limit. However, if income exceeds the basic exemption limit, ITR filing can still become mandatory even if final tax payable is zero.
Basic Exemption Limit for Individuals in AY 2026-27
For individuals, the basic exemption limit depends on the regime and age category. Under the old regime, the limit differs for ordinary individuals, senior citizens and super senior citizens. Under the new tax regime, the nil slab starts up to ₹4,00,000.
| Taxpayer category | Old regime basic exemption | New regime nil slab |
|---|---|---|
| Below 60 years | ₹2,50,000 | ₹4,00,000 |
| Senior citizen, 60 to below 80 years | ₹3,00,000 | ₹4,00,000 |
| Super senior citizen, 80 years or above | ₹5,00,000 | ₹4,00,000 |
The important practical point is this: rebate and exemption limit are different concepts. Rebate may reduce tax payable, but it does not automatically remove the return filing requirement where income crosses the applicable basic limit.
Mandatory ITR Filing Due to High-Value Transactions
Even where income is below the basic exemption limit, ITR filing may still become compulsory if the taxpayer has certain high-value transactions during the financial year.
These conditions are important because they are often reported in AIS and Form 26AS. If a taxpayer does not file a return despite such transactions, the Income Tax Department may ask for an explanation.
| Transaction or condition | Mandatory filing trigger |
|---|---|
| Deposit in one or more current accounts | More than ₹1 crore |
| Deposit in one or more savings accounts | More than ₹50 lakh |
| Foreign travel expenditure | More than ₹2 lakh |
| Electricity consumption expenditure | More than ₹1 lakh |
| Business turnover/sales/gross receipts | More than ₹60 lakh |
| Professional gross receipts | More than ₹10 lakh |
| Aggregate TDS/TCS | ₹25,000 or more |
| Aggregate TDS/TCS for senior citizens | ₹50,000 or more |
These conditions are especially relevant for small businesses, professionals, consultants, freelancers, traders and taxpayers with large banking activity.
Business and Professional Receipts
If a taxpayer is carrying on business and total sales, turnover or gross receipts exceed ₹60 lakh during the financial year, ITR filing becomes mandatory. This applies even if the taxpayer believes that the final taxable income is low.
Similarly, if a professional’s gross receipts exceed ₹10 lakh, ITR filing becomes mandatory. This can apply to doctors, lawyers, consultants, architects, freelancers, designers, accountants and other professionals.
Today, a large amount of financial data is reflected in AIS. GST turnover, TDS details, business receipts and banking information may be available to the department. Therefore, if the reported turnover or receipts cross the mandatory threshold, not filing ITR may increase the risk of a notice.

TDS, TCS and Refund Cases
If total TDS and TCS during the year is ₹25,000 or more, filing becomes mandatory. For senior citizens, this threshold is ₹50,000 or more.
In addition, even where filing is not mandatory, a taxpayer should file ITR if a refund is due. The department will not automatically refund excess TDS unless the taxpayer files a valid return and claims the refund.
For example, if bank TDS, salary TDS, professional TDS or TCS has been deducted and the taxpayer’s final tax liability is lower, filing ITR is required to claim the refund.
Foreign Assets and Foreign Income
If a resident taxpayer holds foreign assets, foreign financial interest, foreign bank account signing authority or foreign income, ITR filing becomes important and, in many cases, mandatory.
This is highly relevant for Indian residents investing in US stocks through platforms such as Vested, INDmoney or similar apps. Even if the investment amount is small, foreign assets may need to be reported in Schedule FA. If there is foreign income, such as dividend or capital gains, Schedule FSI and related foreign tax credit reporting may also become relevant.
Taxpayers should not ignore foreign investments simply because the income is small. Non-reporting of foreign assets can create serious compliance issues.
Loss Carry Forward
If a taxpayer has a loss and wants to carry it forward, timely filing of ITR is important. Business loss, capital loss and certain other losses can generally be carried forward only if the return is filed within the prescribed time.
For example, if a taxpayer has a share market capital loss and wants to set it off against future capital gains, the ITR should be filed correctly and within time. If the return is not filed, or is filed late in cases where timely filing is required, the taxpayer may lose the benefit of carrying forward the loss.
High-Value Transactions in AIS
AIS has made ITR filing more data-driven. If high-value transactions are visible in AIS, the department may expect the taxpayer to either report the transaction in the ITR or explain why it is not taxable.
Examples include large deposits, securities transactions, mutual fund investments, credit card payments, foreign remittances, property transactions and GST-related turnover.
If the transaction is genuine and properly explained in the return, the chances of unnecessary notice reduce. If the taxpayer does not file ITR at all, the department may raise a query asking for the source and nature of the transaction.

Special Relief for Senior Citizens Aged 75 or More
Senior citizens aged 75 years or more may get relief from filing ITR if specific conditions are satisfied. This is not a blanket exemption for all senior citizens.
The conditions include that the senior citizen must be resident in India, should have only pension income and interest income, and the interest should be from the same specified bank where pension is received. The senior citizen must also furnish the required declaration to the specified bank.
Earlier, this declaration was referred to as Form 12BBA. Under the newer form framework, the equivalent declaration may be referred to as Form No. 125. Taxpayers should check the applicable form and bank process before assuming exemption.
If these conditions are not satisfied, the senior citizen may still need to file ITR.
Companies, LLPs and Firms
For companies, LLPs and partnership firms, ITR filing is generally mandatory irrespective of income or loss. A company must file its return even if it has no income or has incurred loss. Firms and LLPs are also required to file returns as applicable.
This is different from individual taxpayers, where the filing requirement depends on income level and prescribed conditions.
Key Takeaways
ITR filing depends on total income and mandatory filing triggers, not merely final tax payable.
Zero tax after rebate does not always mean no ITR is required.
Business turnover above ₹60 lakh and professional receipts above ₹10 lakh trigger mandatory filing.
TDS/TCS of ₹25,000 or more requires filing; for senior citizens, the limit is ₹50,000.
Foreign assets and US stock investments should be reported carefully.
ITR should be filed to claim refunds and carry forward eligible losses.
Companies, LLPs and firms must generally file ITR in all cases.
Conclusion
For AY 2026-27, taxpayers should not decide ITR filing only by checking whether tax payable is zero. The correct approach is to review total income, exemption limits, high-value transactions, TDS/TCS, foreign assets, business receipts, professional receipts and refund or loss carry forward requirements.
Filing ITR correctly helps avoid notices, claim refunds, carry forward losses and maintain a clean tax record. Where AIS shows high-value transactions or foreign investments, professional review is strongly recommended before filing.
