Last updated on: Jun 12, 2026
Section 139 of the Income Tax Act, 1961 is crucial for anyone who earns taxable income in India. Whether you’re an individual, freelancer, business owner, or part of a charitable or religious organisation, knowing the requirements and deadlines under Section 139 can save you from costly penalties. Failing to file your Income Tax Return (ITR) on time can lead to fines, legal issues, and a disrupted financial plan. Stay ahead and ensure you're fully compliant with tax laws, so you don't miss out on essential benefits or face unexpected charges.
Section 139 of the Income Tax Act, 1961 requires taxpayers—individuals, companies, or firms—to file their Income Tax Returns (ITR) if their total income exceeds the non-taxable limit. This section establishes a clear deadline for e-filing to ensure compliance with tax laws. If the deadline is missed, Section 139 allows taxpayers to file a belated return up to the end of the relevant assessment year or before the completion of the assessment, whichever is earlier.
Additionally, Section 139 provides provisions for filing revised returns to correct any errors or omissions in the original filing. This flexibility helps taxpayers maintain compliance and avoid penalties. The section also covers special cases such as charitable organisations and political parties, offering specific filing requirements.
Understanding Section 139 of the Income Tax Act is essential to avoid penalties and ensure timely submission of returns.
There are different forms of error codes under Section 139 of Income Tax Act, 1961. They specify a list of defects for which the assessee may receive a defective return notice. Here is a look at some of the error codes under Section 139 of Income Tax Act, 1961.
ITR is treated as a defective return when the assessee provides a negative amount in gross profit or net profit sections.
If the total income under Section 44AD is less than 8% of gross turnover/gross receipt and the assessee submits ITR‑4S, it will be treated as a defective return.
It is displayed when a taxpayer is having income under the head 'Profits and Gains of Business and Profession', but has not filled the Balance Sheet and Profit and Loss Account.
This code is shown when tax is determined as payable in the return of income filed but not paid.

Section 139(1) of the Income Tax Act, 1961 outlines the mandatory and voluntary requirements for filing Income Tax Returns (ITR). It applies to individuals, businesses, and entities that are required to submit their returns to ensure compliance with tax regulations.
Certain individuals and entities are obligated to file their ITR under Section 139(1) if their total income exceeds the taxable exemption limit. Here’s who falls under this category:
There are certain exemptions available for individuals who meet specific criteria. These exemptions are granted by the Central Government, and the notification must be placed before Parliament for 30 days before they become effective. If both Houses of Parliament agree, the exemption is granted, otherwise, the notification becomes ineffective.
In some cases, individuals or entities are not required by law to file an ITR but may choose to do so voluntarily. Filing a voluntary return is perfectly valid and can be beneficial for various reasons, such as:
It is important to note that voluntary returns do not carry any penalties but must still comply with the Income Tax Act’s filing requirements.
Income Exceeds Exemption Limit: Individuals whose income exceeds the threshold must file by the due date.
Section 139(3) of the Income Tax Act, 1961 covers the filing of Income Tax Returns (ITR) when an individual or entity sustains a financial loss in the previous year. While it may not always be mandatory for individuals, it is crucial for companies and firms to file their returns when they incur a loss to ensure they can carry it forward to offset future income.
For Individuals
For Companies and Firms
Loss from Capital Gains or Business Profits
If an individual, company, or firm incurs a loss under ‘Capital Gains’ or ‘Profits and Gains of Business and Profession,’ they must file the return on time. This ensures the loss can be carried forward to offset future income.
Loss from House Property
Losses incurred from ‘House or Residential Property’ can be carried forward even if the ITR is filed after the due date. This offers flexibility for individuals and firms dealing with real estate-related losses.
Losses from Other Sources
Losses from other sources, such as business or professional losses, cannot be carried forward unless the ITR is filed within the due date. However, losses under house property are an exception.
Losses Being Offset Within the Same Year
A taxpayer can offset a loss against income from a different category within the same fiscal year. This is permitted even if the ITR is filed after the due date.
Filing for a loss return allows you to carry forward the loss, which can reduce your tax liabilities in the future
This is especially beneficial for businesses and individuals with fluctuating income over the years
Unabsorbed depreciation can also be carried forward in certain cases, reducing taxable income in future years
Section 139(4) allows belated returns to be filed up to the end of the relevant assessment year or before completion of assessment, whichever is earlier.
Late filing fee under Section 234F:
₹5,000 if filed late
₹1,000 if income does not exceed ₹5 Lakhs
Fee applies only where filing is mandatory.
Section 139(5) of the Income Tax Act, 1961 allows taxpayers to file a revised Income Tax Return (ITR) if they discover any error, omission, or incorrect statement in the original return. This provision applies to both original returns and belated returns.
A revised return may be filed when:
A taxpayer discovers an error or omission in the original return
The original return was filed under Section 139(1) or Section 139(4)
The revised return must be filed up to the end of the relevant assessment year or before the completion of the assessment, whichever is earlier.
Both original returns and belated returns are eligible for revision
A revised return replaces the originally filed return from the date of filing
Any number of revisions may be made within the permissible time limit
The revised return replaces the original return from the date it was filed
Once filed, the original return is considered withdrawn, and the revised return becomes valid
Revised returns can be used to correct:
Omitted income
Incorrect deductions or exemptions
Errors in income classification or tax computation
Intentional concealment, misrepresentation, or fraudulent reporting is not permitted and may attract penalties and prosecution under the Act.
Section 139(4A) of the Income Tax Act, 1961 outlines the filing requirements for charitable and religious organisations. These organisations must file their Income Tax Returns (ITR) if they earn income from specific sources and their total income exceeds the exemption limit.
Organisations that are charitable or religious trusts are required to file their ITR if they meet certain conditions:
Section 139(4B) requires political parties to file Income Tax Returns (ITR) if their income exceeds the exemption limit, regardless of benefits under Section 13A.
Sections 139(4C) and 139(4D) of the Income Tax Act, 1961 apply to institutions claiming tax exemptions under Section 10. These sections mandate the filing of Income Tax Returns (ITR) if the institution’s income exceeds the exemption limit, regardless of other exemptions.
Section 139(4C) requires institutions to file their return if their total income exceeds the taxable exemption limit, excluding any other exemptions under Section 10. These institutions include:
These institutions must file their ITR in the prescribed form, verifying it according to the requirements.
Section 139(4D) applies to universities, colleges, and other institutions not covered under other provisions. These institutions must file an ITR if they have income or loss, similar to other taxpayers.
Both Section 139(4C) and Section 139(4D) ensure institutions claiming exemptions under Section 10 remain compliant when their income exceeds the exemption limit.
Section 139(4F) of the Income Tax Act, 1961 applies to investment funds mentioned in Section 115UB. This section outlines the filing requirements for these funds, ensuring they comply with tax regulations related to income or loss.
Section 139(9) of the Income Tax Act, 1961 addresses defective returns when required documents or information are missing or incomplete in a filed Income Tax Return (ITR). If the return is deemed defective, the taxpayer is notified by the Assessing Officer (AO) and given an opportunity to correct the issues.
A return is considered defective if the following documents are missing or incorrect:
To prevent your return from being deemed defective, ensure the following documents are included:
If the taxpayer does not maintain books of account, they must submit a statement of gross receipts, turnover, bank balance, expenses, and net profit.
Section 139 of the Income Tax Act, 1961 outlines various deadlines for filing Income Tax Returns (ITR) based on the type of taxpayer and specific conditions. These deadlines are crucial to ensure timely compliance and avoid penalties. Here are the key deadlines for filing ITR:
This is the standard deadline for individuals and entities that do not require an audit. It applies to the following taxpayers:
Salaried employees who do not have additional sources of income
Self-employed individuals or professionals who do not require an audit of their books
Freelancers or consultants without the need for an audit
This deadline is often extended to August 31st by the tax authorities in case of any delays or unforeseen circumstances.
Taxpayers who are required to undergo an audit of their financial accounts must file their Income Tax Returns by October 31st, unless extended by the Central Board of Direct Taxes (CBDT). This deadline applies to:
Business entities whose accounts are subject to audit
Self‑employed individuals or professionals with mandatory audit requirements
Partners of firms where the firm’s accounts are audited
The government may extend this deadline in special circumstances.
Under Section 139 of the Income Tax Act, 1961, taxpayers are required to file accurate Income Tax Returns (ITR). If the return contains errors or missing information, it may be deemed defective. The Assessing Officer (AO) assigns specific error codes to highlight these issues. Here’s a breakdown of some common error codes under Section 139:
This error occurs if the assessee provides a negative amount in the Gross Profit or Net Profit sections of the ITR. Such entries result in the return being marked as defective.
If the total income under Section 44AD is less than 8% of gross turnover or gross receipts and the assessee submits ITR‑4S, the return will be treated as a defective return.
When the taxpayer has income under the head 'Profits and Gains of Business and Profession' but fails to include the Balance Sheet and Profit and Loss Account, the return is considered defective.
This error occurs when tax is determined as payable in the ITR, but the tax has not been paid. The return will remain defective until the payment is made.
To avoid these common defective return errors, ensure that:
All figures provided are accurate and reasonable
The appropriate forms are filed, especially if using presumptive income under Section 44AD
All necessary documents, such as the Balance Sheet and Profit and Loss Account, are included
The tax payable is correctly paid and reflected in the return

Here’s an overview of the recent amendments to Section 139 of the Income Tax Act, which bring important changes to return filing and revision processes for taxpayers:
The words 'provisions of section 10A' were replaced with 'provisions of clause (38) of section 10 or section 10A' from 1st April 2017.
The phrase 'or sub-section (2) of section 73A' was added after 'sub-section (2) of section 73' in sub-section (3).
