Is ITR filing compulsory below the taxable limit?

Not always. Whether you must file depends on your income before deductions compared with the basic exemption limit, not on whether you end up paying tax. If your income is under the limit and no special condition applies, filing is optional. If it is above the limit, you must file even when the rebate brings your tax to zero.

The figures below are signed off for the tax year 2025-26. For the tax year 2026-27 they are provisional: they repeat the 2025-26 values and have not yet been signed off against the Income-tax Act, 2025.

"Taxable limit" means two different things

People say "taxable limit" for two different numbers, and mixing them up is the main source of confusion.

The rebate is why a salaried person earning ₹10,00,000 can owe nil tax in the new regime. It does not remove the duty to file. The filing test looks at your gross total income, which is your income from all heads before the deductions in the deduction chapter, so a ₹1,50,000 investment under section 80C does not bring you below the limit either.

When you must file even with low income

TaxCare's rules check these conditions:

• Income above the limit for your age, as in the table above.
• TDS and TCS together of ₹25,000 or more (₹50,000 or more for a senior or super senior citizen).
• Other specified triggers, which TaxCare records as a "mandatory filing trigger". For an individual or HUF these are, under the 1961 Act:
• business turnover above ₹60 lakh in the year;
• gross receipts from a profession above ₹10 lakh;
• deposits of ₹50 lakh or more in one or more savings bank accounts;
• deposits above ₹1 crore in one or more current accounts;
• spending above ₹2 lakh on foreign travel for yourself or anyone else;
• an electricity bill above ₹1 lakh for the year.

These conditions come from the seventh proviso to section 139(1) and rule 12AB of the 1961 Act, and apply to the tax year 2025-26. Their counterparts under the Income-tax Act, 2025 for the tax year 2026-27 are not covered in this guide.

Cases where you may skip the return

If your gross total income is below your limit, no TDS-and-TCS threshold is crossed and none of the special triggers applies, you are not required to file. Typical examples are a student with a small stipend, a homemaker with a little interest income, or a pensioner whose pension is below the senior citizen limit.

Why many people file anyway

Even when it is optional, a return is often the better choice:

• To claim a refund. If TDS was deducted on interest or salary and your actual tax is lower or nil, the only way to get the money back is to file.
• To keep an income record. Banks, visa offices and credit-card issuers often ask for returns as proof of income.
• To carry forward a loss. A capital loss or business loss can be carried forward only if the return is filed on time.
• To keep your records clean. The department already holds your salary, interest and transactions in your AIS. A return that agrees with it avoids questions later.

What happens if you file late but were never required to

On TaxCare's rules, the late fee under section 234F is charged only on a person who was required to file. A late return from someone below the limit owes no fee. Interest for late payment applies only where there is tax to pay.

How to check your own position

1. Open your AIS and Form 26AS (Form 168 from the tax year 2026-27) and add up your income from every source.
2. Compare the total with the limit for your age.
3. Add up the TDS and TCS shown against your PAN.
4. Ask whether any special trigger applies, such as a foreign asset or large cash deposit.
5. If you are close to a limit, file. A return you did not need costs a little time. A return you needed and missed can cost a fee, interest and a notice.

How TaxCare helps

TaxCare brings your AIS, TIS and Form 26AS or Form 168 from the Income Tax portal after you confirm with an OTP, adds up your income and TDS, and tells you whether your figures cross the filing thresholds. If you only want a refund, it shows how much excess TDS there is before you decide. Nothing is submitted until you approve the return. See how pricing works.
