Who Must File an Income Tax Return in India? Complete Guide for FY 2025-26

Filing an Income Tax Return (ITR) is one of the most important financial responsibilities for individuals and businesses in India. But many taxpayers are still confused about who is actually required to file — especially when their tax liability works out to zero.

The answer has changed dramatically over the years. Today, ITR filing is no longer just about whether you earned above a certain income. It is also triggered by high-value transactions, foreign assets, business turnover, and more.

This guide covers every mandatory filing scenario for Financial Year 2025-26 (Assessment Year 2026-27) — in plain language.

1. The Basic Rule: Income Exceeding the Exemption Limit

The most fundamental rule is simple: if your gross total income exceeds the basic exemption limit, you must file an ITR.

⚠️ Important: The threshold is tested on your gross income — before deductions under Chapter VI-A (80C, 80D, 80G, etc.) or capital gains exemptions (Sections 54, 54F, etc.). Even if deductions bring your final tax to zero, you must still file.

Exemption Limits for FY 2025-26

| Taxpayer Category | Old Tax Regime | New Tax Regime (Default) | |---|---|---| | Individuals below 60 years, HUFs, AOPs | ₹2,50,000 | ₹4,00,000 | | Senior Citizens (60–79 years) | ₹3,00,000 | ₹4,00,000 | | Super Senior Citizens (80+ years) | ₹5,00,000 | ₹4,00,000 | | NRIs (all ages) | ₹2,50,000 | ₹4,00,000 |

Under the New Tax Regime (now the default), a flat ₹4,00,000 limit applies uniformly to all age groups.

What About the ₹12 Lakh Tax-Free Income?

Under the New Tax Regime, taxpayers with income up to ₹12,00,000 get a full rebate under Section 87A (₹60,000 rebate). For salaried individuals, the standard deduction of ₹75,000 extends this to ₹12,75,000 effectively.

But the rebate does NOT remove the filing obligation. If your gross income exceeds ₹4,00,000, you must still file — even if you owe zero tax.

2. Companies and Firms: Mandatory Filing, No Exceptions

For incorporated and registered entities, there is no income threshold — filing is absolutely compulsory every year.

Companies (ITR-6)

Every company registered under the Companies Act must file an ITR, regardless of:

Whether it has started operations
Whether turnover is zero
Whether it is running at a loss
Whether it holds "dormant" status

This includes private limited companies, public limited companies, OPCs, Section 8 companies, and foreign company branches operating in India.

Partnership Firms and LLPs (ITR-5)

All traditional partnership firms and Limited Liability Partnerships (LLPs) must file an annual ITR — even with zero revenue or massive losses. This is required to carry forward losses, validate partner remuneration, and maintain regulatory standing.

3. Residents with Foreign Assets: File Regardless of Income

If you are a Resident and Ordinarily Resident (ROR) in India, you must file an ITR if at any point during the year you:

Hold any asset outside India — foreign real estate, foreign shares, overseas retirement accounts, ESOPs from a foreign employer
Have a financial interest in any foreign entity
Hold signing authority in any foreign bank or brokerage account (even a zero-balance account)
Are a beneficiary of any foreign asset or trust

This applies even if your Indian income is below the exemption limit. Such taxpayers must use ITR-2 or ITR-3 and complete Schedule FA (Foreign Assets) and Schedule FSI (Foreign Source Income). Non-disclosure can attract severe penalties under the Black Money Act, 2015.

4. NRIs: When Is Filing Required?

NRIs are taxed only on income earned or received in India — not on global income. Common Indian-source income includes:

Salary for services rendered in India
Rental income from Indian property
Interest on NRO fixed deposits
Capital gains from Indian assets (shares, mutual funds, property)

Note: Interest on NRE accounts is fully tax-free.

An NRI must file an ITR if their India-sourced gross income exceeds ₹4,00,000 (New Regime) or ₹2,50,000 (Old Regime). Age-based concessions (₹3L or ₹5L) do not apply to NRIs.

Special NRI trigger: Even if total Indian income is below the threshold, an NRI must file if they have:

Short-Term Capital Gains (STCG) on equity shares or mutual funds, or
Any taxable Long-Term Capital Gains (LTCG)

5. The Seventh Proviso to Section 139(1): High-Value Transaction Triggers

This is one of the most important reforms in recent years. Introduced in 2019, the Seventh Proviso mandates ITR filing for anyone — regardless of income — who meets any of the following in a financial year:

Trigger 1: Current Account Deposits Exceeding ₹1 Crore

If you deposit more than ₹1 crore (in aggregate across all current accounts across all banks), you must file. This includes cash, cheques, and digital transfers (NEFT/RTGS/UPI).

Why it matters: Targets large unorganized traders who manage high cash flow but declare minimal income.

Trigger 2: Foreign Travel Expenditure Exceeding ₹2 Lakh

If you spend more than ₹2 lakh on international travel — for yourself or anyone else — you must file. This covers airfare, visa fees, and accommodation, whether paid in India or abroad.

Why it matters: International travel is a clear indicator of financial capacity that may not match declared income.

Trigger 3: Electricity Bill Exceeding ₹1 Lakh

If your aggregate electricity consumption charges cross ₹1 lakh in the year, filing is mandatory — even if the connection is in another person's name.

Why it matters: High electricity usage signals large property or industrial activity, inconsistent with nil-income declarations.

6. Rule 12AB: Additional Triggers Added in 2022

The CBDT expanded the net further via Rule 12AB (effective AY 2022-23 onwards), adding four more triggers:

| Trigger | Threshold | Who It Targets | |---|---|---| | Business Sales / Turnover / Gross Receipts | Exceeds ₹60 Lakh | Mid-size traders and retailers | | Professional Gross Receipts | Exceeds ₹10 Lakh | Consultants, freelancers, IT professionals | | Aggregate TDS/TCS (Non-Senior Citizens) | ₹25,000 or more | Gig workers, commission agents, FD interest earners | | Aggregate TDS/TCS (Senior Citizens 60+) | ₹50,000 or more | Retirees with FDs and SCSS income | | Savings Account Deposits (aggregate) | ₹50 Lakh or more | Informal operators diverting receipts to savings accounts |

The ₹50 Lakh savings account trigger specifically closed a loophole where business operators were routing current account volumes into personal savings accounts to avoid the ₹1 Crore current account rule.

7. Filing to Carry Forward Losses (Section 139(3))

Even if none of the above apply, you must file an ITR on time if you want to carry forward:

Business or professional losses (carry-forward up to 8 years)
Capital losses — short-term or long-term (up to 8 years)
Speculative business losses (up to 4 years)

⚠️ If you miss the due date, your right to carry forward these losses is permanently lost. No exceptions.

Exception: House property losses and unabsorbed depreciation can be carried forward even with a belated return.

8. Filing to Claim a TDS Refund

If your employer, bank, or client has deducted TDS but your actual tax liability is zero (because your income is below the threshold), the government will not automatically refund the TDS.

You must file an ITR to claim the refund. This is especially common for:

Freelancers earning below ₹4 lakh with 10% TDS deducted by clients
Fixed deposit holders with TDS deducted at 10%
Students or homemakers with FD interest below the taxable limit

Even a "Nil Return" builds your financial record and helps with loan applications, visa processing, and subsidy eligibility.

9. Who Is Exempt? The Section 194P Carve-Out

Senior citizens aged 75 years or above are exempt from filing an ITR if ALL of the following conditions are met:

Income consists only of pension and interest income
The interest income is from deposits in the same bank where pension is credited
The senior citizen submits Form 12BBA to that bank
The bank deducts the applicable TDS on their behalf

Once these conditions are satisfied, the bank handles the tax, and no separate ITR filing is required.

10. Which ITR Form Should You Use?

| Form | Who Should Use It | |---|---| | ITR-1 (Sahaj) | Salaried individuals, one house property, income up to ₹50 lakh (no foreign assets, no business income) | | ITR-2 | Individuals/HUFs with capital gains, multiple properties, or foreign assets | | ITR-3 | Individuals/HUFs with business or professional income | | ITR-4 (Sugam) | Presumptive taxation filers (Sections 44AD, 44ADA, 44AE), income up to ₹50 lakh | | ITR-5 | Partnership firms, LLPs, AOPs, BOIs | | ITR-6 | All companies | | ITR-7 | Trusts, political parties, research institutions, universities |

Company directors and holders of unlisted shares cannot use ITR-1 or ITR-4 — they must use ITR-2 or ITR-3.

11. Key Deadlines for AY 2026-27

| Taxpayer Category | Due Date | |---|---| | Individuals, HUFs (no audit required) | July 31, 2026 | | Non-audit business/professional taxpayers | August 31, 2026 | | Companies, LLPs, audit cases (Section 44AB) | October 31, 2026 | | Transfer pricing cases (Section 92E) | November 30, 2026 |

12. Penalties for Missing the Deadline

Late Filing Fee (Section 234F)

Income above ₹5 lakh → ₹5,000 flat fee
Income below ₹5 lakh → ₹1,000 flat fee

Penal Interest (Section 234A)

1% per month on outstanding tax from the day after the due date until the return is actually filed.

Belated returns (under Section 139(4)) can be filed until December 31, 2026, but loss carry-forward rights are permanently forfeited.

13. The New Income Tax Act, 2025: What Changes?

From April 1, 2026, the Income Tax Act, 2025 replaces the 1961 Act. Key changes relevant to ITR filing:

No more "Assessment Year" — replaced by a single "Tax Year" (e.g., Tax Year 2026-27)
Section 263 replaces Section 139 as the primary filing mandate section
High-value transaction triggers are now part of the main law (not just a proviso)
Revised return window extended to 12 months (from 9 months), with a nominal fee for the extra 3-month window
Expanded PAN requirements: cash deposits above ₹10 lakh and property deals above ₹20 lakh will now require PAN, feeding directly into automated scrutiny

ITRs filed in 2026 (for FY 2025-26) will still follow the 1961 Act rules. The 2025 Act governs income earned from April 1, 2026 onwards.
