Minimum Salary to File ITR in India (2026): Real Threshold vs Mandatory Filing

The minimum salary that legally requires you to file an Income Tax Return in India for FY 2025-26 (AY 2026-27) is ₹4 lakh per year under the new tax regime and ₹2.5 lakh under the old tax regime (raised from ₹3 lakh in Budget 2025 for the new regime; PIB, Feb 2025). But this answer is incomplete - and that's where most first-time filers go wrong. Filing isn't decided by salary alone. Section 139(1) of the Income Tax Act lists nine separate triggers that force you to file even at ₹0 income, and TDS already deducted from your bank interest or salary creates a legitimate refund opportunity that vanishes if you skip filing.

What is the minimum salary to file ITR in India for FY 2025-26?

The threshold depends entirely on which tax regime you choose. Budget 2025 raised the new regime's basic exemption from ₹3 lakh to ₹4 lakh, effective FY 2025-26 (PIB, Feb 1, 2025). Here are the exact thresholds at which filing becomes legally mandatory:

• New tax regime (default): Gross income above ₹4,00,000 per year
• Old tax regime - below 60 years: Gross income above ₹2,50,000
• Old tax regime - 60 to 80 years (senior citizens): Gross income above ₹3,00,000
• Old tax regime - above 80 years (super senior citizens): Gross income above ₹5,00,000

The word "gross" matters. The threshold applies to your income before any deduction - before standard deduction, before Section 80C, before HRA. So if your CTC is ₹4.2 lakh and you claim the ₹75,000 standard deduction to bring taxable income to ₹3.45 lakh, you still must file because gross income exceeds ₹4 lakh.

Why salaried people earning ₹12 lakh still pay zero tax

72% of taxpayers have switched to the new regime as of AY 2024-25 (PIB/CBDT, Aug 2024), and the math is straightforward: under the new regime, salaried employees get a ₹75,000 standard deduction plus a Section 87A rebate of up to ₹60,000 on tax payable for income up to ₹12 lakh. Combined, this means a salaried individual earning up to ₹12.75 lakh in CTC pays zero income tax - but they're still legally required to file an ITR because their gross income exceeds ₹4 lakh.

When does filing become mandatory below the ₹4 lakh threshold?

Section 139(1) of the Income Tax Act, 1961, defines nine specific situations where you must file ITR even if your gross income is below the basic exemption limit. These are called "specified transaction" triggers, and CBDT has expanded them over the past five years to bring high-spending but low-declared-income individuals into the tax net:

• Bank deposits: Aggregate cash deposits ≥ ₹1 crore in current accounts, or ≥ ₹50 lakh in savings accounts during the financial year
• Foreign travel: Personal expenditure ≥ ₹2 lakh on foreign travel for self or any other person
• Electricity bill: Annual electricity consumption ≥ ₹1 lakh
• Business turnover: Gross receipts from business exceed ₹60 lakh, or from profession exceed ₹10 lakh
• TDS / TCS deducted: Total TDS plus TCS ≥ ₹25,000 (₹50,000 for senior citizens) - this is the most common trigger for low-income individuals
• Foreign assets / signing authority: Any foreign asset ownership, beneficial interest, or signing authority over a foreign account requires filing under Schedule FA - regardless of income
• Savings account deposits: Deposits in savings accounts ≥ ₹50 lakh during the year

The TDS trigger catches most first-time filers off guard. If your bank deducted ₹26,000 TDS on fixed deposit interest, you must file - even if your total income is ₹2.8 lakh and you owe zero tax. The good news: filing is the only way to claim that ₹26,000 back as a refund.

Should you file ITR even when not legally required?

Yes - voluntary filing builds practical leverage that goes beyond tax compliance. The Income Tax Department issued ₹3.5 lakh crore in refunds in FY 2024-25, and 38% of these went to salaried taxpayers whose TDS exceeded their final tax liability (CBDT data, Mar 2025). Without filing, that money stays with the government. Beyond refunds, voluntary filing creates four documented benefits:

• Loan eligibility: HDFC, ICICI, SBI and most NBFCs require 2–3 years of ITRs as primary income proof for home loans, business loans, and personal loans above ₹5 lakh
• Visa applications: US, UK, Schengen, Australia and Canada visa interviews systematically check 3 years of ITRs - bank statements alone don't suffice
• Loss carry-forward: Capital losses (equity, mutual funds, F&O) can be carried forward up to 8 years to offset future gains - but only if you file the loss return on time
• Credit card limit increases and insurance underwriting: Term insurance for cover above ₹50 lakh increasingly requires verified ITR copies

What happens if you don't file when you should?

Two cost layers apply: a fixed late filing fee under Section 234F, and interest on unpaid tax under Section 234A/B/C. The penalty structure under Section 234F is:

• Income up to ₹5 lakh: ₹1,000 late filing fee
• Income above ₹5 lakh: ₹5,000 late filing fee
• Filing after December 31, 2026 (for FY 2025-26): Belated return only - the ITR-U updated return window extends 24 months but with additional 25–50% tax penalty

On top of the late filing fee, Section 234A charges 1% per month simple interest on any unpaid tax from August 1, 2026 (the day after the deadline) until the date you actually pay. For a salaried person with ₹15,000 tax due, filing in November means an additional ₹450 in interest plus the ₹5,000 Section 234F penalty - a 36% effective surcharge on the original tax liability.

Can you file an ITR for previous years you missed?

Yes, through ITR-U (Updated Return) introduced in Budget 2022 and expanded in Budget 2025. ITR-U lets you file or revise returns for up to 4 assessment years back, with an additional tax of 25% (within 12 months of the relevant AY end), 50% (within 12–24 months), 60% (within 24–36 months), or 70% (within 36–48 months) on top of the regular tax. For FY 2025-26, ITR-U remains available until March 31, 2030. It's a release valve - not a substitute for filing on time.

How to file when you're below the threshold but want a refund

If your gross income is below ₹4 lakh and you only want to claim a TDS refund, the process is the simplest version of ITR filing - typically 15–25 minutes on the income tax portal:

1. Log into incometax.gov.in using PAN as user ID
2. Select "File Income Tax Return" → AY 2026-27 → Online mode → ITR-1 (Sahaj)
3. The portal pre-fills your income data from AIS (Annual Information Statement) and Form 26AS - verify the salary and TDS figures match your Form 16
4. Confirm tax regime selection - new regime is the default; switching to old regime requires Form 10-IEA only if you have business income
5. The portal calculates refund automatically - submit and e-verify within 30 days using Aadhaar OTP, net banking, or DSC

The full step-by-step walkthrough is covered in our first-time ITR filing guide, including what to do when AIS data doesn't match Form 16. For freelancers and small business owners whose threshold rules differ, see who needs to file ITR in India.

Frequently asked questions

Is there any minimum salary below which I cannot file ITR?

No. There is no lower limit on filing. You can file an ITR even with ₹0 income (a "nil return") - and many first-time filers do, specifically to claim TDS refunds on bank interest, build income history for loans, or carry forward capital losses from equity investments.

If my salary is ₹3 lakh, do I need to file ITR?

Under the new regime, filing is not legally mandatory at ₹3 lakh because the threshold is ₹4 lakh. Under the old regime, ₹3 lakh exceeds the ₹2.5 lakh threshold (below 60 years), so filing is mandatory. Also check: if any TDS was deducted (typically on bank FD interest above ₹40,000), you must file regardless to claim the refund.

Do I need to file ITR if I earn ₹6 lakh and pay zero tax under the new regime?

Yes. The Section 87A rebate brings your tax liability to zero, but it doesn't eliminate the requirement to file. Any gross income above ₹4 lakh under the new regime triggers mandatory filing under Section 139(1).

What's the minimum income for senior citizens to file ITR?

Under the old regime: ₹3 lakh for citizens aged 60–80 years, ₹5 lakh for citizens above 80 years. Under the new regime, the basic exemption is ₹4 lakh regardless of age - there are no age-based slabs in the new regime. Senior citizens above 75 years with only pension and bank interest income from a specified bank can opt out of filing entirely under Section 194P.

If I'm a student earning ₹2 lakh from internships and freelance work, do I need to file?

Below the basic exemption, filing isn't mandatory - but freelance income reported on Form 26AS with TDS deducted (commonly 10% under Section 194J for professional services) means you can claim a full refund by filing ITR-3 or ITR-4. Most students earning under ₹4 lakh from freelance work get 100% of TDS back.

Understanding the minimum salary to file ITR is the first step - but the bigger question for most first-time filers is whether voluntary filing is worth the effort. The data is clear: ₹3.5 lakh crore in refunds processed in FY 2024-25, growing visa rejection rates without ITR history, and compounding loss carry-forward benefits all argue in favor of filing whenever there's any TDS deducted or income proof needed. If you're unsure whether your specific situation triggers mandatory filing, a quick tax consultation resolves it in under 15 minutes - saving 4 years of ITR-U penalty exposure.
