Filing your Income Tax Return (ITR) is an essential responsibility for taxpayers in India. Income Tax Section 139(1) of the Income Tax Act, 1961, explains the rules for mandatory and voluntary filing of returns. It covers individuals, companies, and other entities.
ITR filing FY25: IT dept extends last date for filing returns on income tax for FY25 from July 31 to 15 September 2025
The Income Tax Department has officially extended the last date for filing Income Tax Returns (ITRs) for the financial year 2024-25 (assessment year 2025-26). Originally set at 31 July 2025, the due date has now been moved to 15 September 2025. This applies to individual taxpayers and Hindu Undivided Families (HUFs) who do not need to have their accounts audited.
The extension has been announced to help taxpayers manage delays in accessing updated ITR forms and filing systems. The new forms have introduced changes aimed at making the process simpler, more transparent, and better aligned with digital systems. Additional time was needed to adjust backend systems and utilities accordingly.
Salaried individuals, freelancers, and small business owners who are not subject to audits will benefit from this relief, as they now have more time to collect documents and file without last-minute pressure.
Meanwhile, those who are required to get their accounts audited must still file their ITRs by 31 October 2025. Taxpayers are advised to file within the extended timeline to avoid late fees under Section 234F, which can go up to Rs. 5,000 for delayed submissions.Here’s everything you need to know about this section, explained in simple terms.
What is Section 139(1) of the Income Tax Act?
Section 139(1) of the Income Tax Act outlines who is legally required to file an Income Tax Return in India. It covers both mandatory and voluntary returns. Here are the key cases where filing under this section is necessary:
- Any individual whose total income exceeds the exemption limit must file their return before the due date.
- Companies—whether public, private, Indian, or foreign—operating in India must file their return.
- Firms, including Limited Liability Partnerships (LLP) or Unlimited Liability Partnerships (ULP), are also covered under this requirement.
- Indian residents who own assets abroad or are authorised signatories for foreign accounts must file a return, regardless of their income.
- HUFs (Hindu Undivided Families), AOPs (Association of Persons), and BOIs (Body of Individuals) are also required to file if their total income exceeds the tax-free threshold.
Section 139(1c) provides some relief. It allows certain categories of individuals to be exempt from filing returns, provided they meet specific conditions laid out by the government. These exemptions must be formally approved by both Houses of Parliament.
Additionally, voluntary returns can be filed by individuals whose income is below the taxable limit. Even though these returns are not required by law, they are treated as valid filings and can be useful in claiming refunds or carrying forward losses.Let’s look at who must file under this section.
Who needs to file ITR under Section 139(1)?

1. For companies

- Private companies
- Domestic companies
- Foreign companies
2. For firms
Every firm, including:
- Limited liability partnerships (LLPs)

5. Other entities
Entities like Hindu Undivided Families (HUFs), Associations of Persons (AOPs), and Bodies of Individuals (BOIs) must file ITR if their income exceeds the exemption limit.
ITR filing deadlines under Section 139(1)
As per Section 139(1) of the Income Tax Act, individuals and entities not required to audit their accounts must file their ITR by 31 July of the relevant assessment year. This deadline applies to salaried individuals, freelancers, small business owners, and Hindu Undivided Families (HUFs). If their income exceeds the basic exemption limit, they are legally required to file their returns on time. Filing after this date may attract penalties under Section 234F.

Penalties and fees for late ITR filing under Section 139(1)
If you fail to file your Income Tax Return by the due date specified under Section 139(1), you may have to pay a late fee of up to Rs. 5,000. However, if your total income is Rs. 5 lakh or less, the maximum penalty is reduced to Rs. 1,000. This fee is levied under Section 234F of the Income Tax Act. To avoid these charges, it’s important to file your return on or before the due date, even if your tax liability is nil or minimal.
