Every year, as the ITR filing season opens, the same question comes up repeatedly: do I actually have to file a return? Many people assume that if they have no tax to pay, or if their employer has already deducted TDS, there is nothing left to do. This assumption is incorrect and can be costly. Filing an income tax return is not just about paying tax. It is a legal obligation for many people, a financial necessity for others, and a smart habit for almost everyone. This article explains clearly who must file a return for FY 2025-26, what triggers mandatory filing even when income is below the taxable limit, and why filing voluntarily still makes sense even when it is not strictly required.
What Is an Income Tax Return
An income tax return, commonly called an ITR, is a formal document filed with the Income Tax Department that declares your total income earned during the financial year, the tax you have already paid or that has been deducted, and any tax that remains payable or is due back to you as a refund. For FY 2025-26, the ITR covers income earned between 1st April 2025 and 31st March 2026, and is filed in Assessment Year 2026-27. The return must be filed in the prescribed form, verified in the prescribed manner, and submitted by the applicable due date.
Who Must File an ITR: The Basic Income Rule
The most fundamental trigger for mandatory ITR filing is crossing the basic exemption limit. Under Section 139(1) of the Income Tax Act, every individual whose income before claiming deductions under Chapter VI-A and before claiming capital gain exemptions exceeds the basic exemption limit must file a return. This is important: the test is based on gross income before deductions, not the taxable income after deductions. Even if your final tax liability is zero because of deductions or the Section 87A rebate, you are still required to file if your gross income crosses the threshold.
Every company and every partnership firm must file a return regardless of whether they made a profit or a loss during the year. There is no income threshold exemption for companies and firms.
When You Must File Even If Income Is Below the Exemption Limit
This is the part that most taxpayers are unaware of. The law prescribes several specific situations where ITR filing becomes mandatory regardless of income level. These are triggered by high-value financial activity or specific asset holdings that indicate financial capacity beyond what income alone might suggest.
Under Rule 12AB of the Income Tax Rules, a person not otherwise required to file a return must still file one if any of the following conditions are met during the year.
- First, if total sales, turnover, or gross receipts from business exceed Rs 60 lakh.
- Second, if total gross receipts from a profession exceed Rs 10 lakh.
- Third, if the aggregate of TDS and TCS deducted during the year is Rs 25,000 or more. For senior citizens aged 60 years or above, this threshold is Rs 50,000.
- Fourth, if the aggregate deposits in one or more savings bank accounts during the year are Rs 50 lakh or more.
Beyond Rule 12AB, Section 139(1) also makes filing mandatory in the following situations.
- If you have deposited more than Rs 1 crore in one or more current accounts during the year, filing is required.
- If you have spent more than Rs 2 lakh on foreign travel, whether for yourself or for any other person, filing is required.
- If your electricity consumption for the year exceeded Rs 1 lakh in total, filing is required.
These conditions were introduced specifically to bring people with significant spending power into the tax net even when their declared income appears low.
Special Rule for Residents With Foreign Assets
If you are a Resident and Ordinarily Resident in India and you hold any asset outside India at any time during the year, you must file an ITR regardless of your income level. This includes any foreign bank account, shares in a foreign company, property outside India, or any financial interest in any foreign entity. Even if you are a beneficiary of a foreign asset, meaning someone else holds it but you benefit from it, the filing obligation applies.
This rule is strict and the consequences of non-compliance are serious. The Black Money Act imposes a penalty of Rs 10 lakh per year for failure to report foreign assets, and in serious cases prosecution is possible. Being unaware of the requirement is not treated as a valid defence once a notice is issued.
NRI Taxpayers: When Filing Is Required and When It Is Not
Non-Resident Indians are taxed in India only on income earned in India or received in India. An NRI must file an ITR if their Indian income exceeds the basic exemption limit applicable to non-residents, which is Rs 2,50,000 under the old regime. Unlike residents, NRIs do not get the benefit of the enhanced exemption limits available to senior and super senior citizens under the old regime.
If an NRI wishes to claim a refund of excess TDS deducted, filing a return is the only way to do so, even if the income is below the exemption limit or is otherwise not taxable in India due to DTAA provisions.
Who Should File Voluntarily Even When Not Legally Required
Even when filing is not strictly mandatory, there are strong practical reasons to file an ITR every year.
- The first and most immediate reason is claiming a TDS refund. If tax has been deducted at source from your interest income, salary, or professional fees, and your actual tax liability is lower, the only way to recover the excess is by filing a return. Without filing, the refund is simply not processed.
- The second reason is carrying forward losses. If you have made a loss from capital gains or from a business or profession, you can carry it forward to set off against future income, but only if the return is filed on or before the original due date. A belated return does not generally allow most losses to be carried forward.
- The third reason is financial documentation. Banks require at least two to three years of filed ITRs when processing home loans, car loans, or business loans. Visa applications for several countries, also ask for ITR acknowledgements as proof of income and financial standing. A filed ITR is one of the cleanest and most widely accepted documents for these purposes.
- The fourth reason is simply building a clean financial record. A consistent history of filed returns demonstrates financial responsibility and makes compliance much easier when income increases in future years and filing becomes mandatory.
Due Dates for Filing for FY 2025-26
Getting the due date right is as important as getting the return right. For most salaried individuals and others filing ITR-1 or ITR-2, the due date is 31st July 2026. For those filing ITR-3 or ITR-4 with business or professional income not requiring an audit, the due date is 31st August 2026. For cases requiring a tax audit, the audit must be completed and the return filed by 31st October 2026. For cases involving international transactions requiring a transfer pricing report, the return deadline is 30th November 2026.
Missing the original due date means a belated return can be filed up to 31st December 2026 under Section 139(4), but with a late filing fee under Section 234F of Rs 5,000 for those with income above Rs 5 lakh, and Rs 1,000 for those with income up to Rs 5 lakh. Interest under Section 234A also applies on any unpaid tax for the period of delay.
Updated Return: A Safety Net With a Four-Year Window
If you have already filed your return but later realise you missed some income or made an error, Section 139(8A) provides for an updated return. An updated return can be filed within 48 months from the end of the relevant assessment year. For AY 2026-27, this window remains open until 31st March 2031. However, an updated return can only be used to declare additional income and pay additional tax. It cannot be used to claim a refund, reduce an existing tax liability, or declare a loss.
What Happens If You Do Not File
The consequences of not filing when required go beyond the late fee. If the department has information suggesting you have unreported income, it can initiate assessment proceedings, which can result in a tax demand, interest, and penalties. In serious cases involving deliberate tax evasion, prosecution is possible. Practically speaking, missing the return also means losing the ability to carry forward losses, missing the chance to claim refunds, and creating gaps in your financial record that can affect loan applications and visa processes for years afterward.
Frequently Asked Questions
1. My income is below Rs 12 lakh and I pay zero tax under the new regime. Do I still need to file an ITR? Yes, if your income before deductions exceeds the basic exemption limit of Rs 4,00,000 under the new regime. The Section 87A rebate reduces your tax to zero, but the obligation to file is based on your gross income, not your final tax payable.
2. My employer has deducted full TDS. Is filing still required? Yes, if your gross income exceeds the basic exemption limit. TDS deduction by the employer satisfies the tax payment obligation but does not replace the return filing obligation. Filing is still required, and it is also the only way to claim a refund if TDS was over-deducted.
3. I have savings bank deposits of Rs 60 lakh but my income is only Rs 3 lakh. Do I need to file? Yes. Under Rule 12AB, deposits of Rs 50 lakh or more in savings accounts trigger a mandatory filing obligation regardless of income level.
4. What is the last date to file ITR for FY 2025-26 for a salaried individual? 31st July 2026 for those filing ITR-1 or ITR-2 without any audit requirement. For ITR-3 and ITR-4 non-audit cases, the due date is 31st August 2026.
5. Can I file after the due date? Yes. A belated return can be filed up to 31st December 2026 under Section 139(4), but it attracts a late filing fee under Section 234F and interest under Section 234A on any unpaid tax. Most losses also cannot be carried forward from a belated return.
6. What is an updated return and how long do I have to file one? An updated return under Section 139(8A) allows you to correct omissions or declare additional income after the original or revised return deadline has passed. It can be filed up to 48 months from the end of the assessment year. It cannot be used to claim a refund or reduce tax liability.
7. I hold a foreign bank account. Do I need to file even if my income is low? Yes. Every Resident and Ordinarily Resident individual who holds any asset outside India, including a foreign bank account, must file an ITR under Section 139(1) regardless of their income level.
