ITR Filing Deadline for Startups in 2025
Startups, irrespective of whether they generate revenue or operate at a loss, are required to file their income tax returns annually under the Income Tax Act, 1961. For the financial year 2024-25 (assessment year 2025-26), the due date for non-audit cases has been set as September 16, 2025. This date was extended by one day from the original September 15 due to technical issues on the income tax portal. For startups that fall under audit requirements because of turnover thresholds or other compliance conditions, the filing deadline is October 31, 2025. Meeting these deadlines ensures that startups stay compliant, maintain financial transparency, and retain credibility with investors and financial institutions.
ITR Filing Deadline for LLPs in 2025
Limited Liability Partnerships (LLPs) must file their returns using the ITR-5 form. The deadlines depend on turnover and audit requirements. For LLPs with an annual turnover below Rs. 40 lakhs or partner capital contributions below Rs. 25 lakhs, the filing deadline is July 31, 2025. However, LLPs exceeding these thresholds must undergo a mandatory tax audit, shifting their deadline to September 30, 2025. Alongside income tax return filing, LLPs are also obligated to file Form 8 (Statement of Account and Solvency) with the Ministry of Corporate Affairs by October 30 each year, requiring audited accounts.
Applicable ITR Forms for Startups and LLPs
The correct ITR form depends on the structure and nature of income. Startups operating as private limited companies generally use ITR-6, unless they claim exemptions under Section 11. Founders earning personal income from salary, freelancing, or capital gains may need to file ITR-1, ITR-3, or ITR-4, depending on the sources of income. LLPs are required to file ITR-5, which is specifically designed for partnership firms and LLP structures. Choosing the right form is critical to avoid rejection or scrutiny from tax authorities.
Penalties for Late ITR Filing in 2025
Missing the deadline attracts penalties and interest. Under Section 234F, a penalty of up to Rs. 5,000 applies if the total income exceeds Rs. 5 lakh. For incomes below this limit, the penalty is capped at Rs. 1,000. Additionally, interest under Section 234A is charged at 1% per month on any outstanding tax liability. These penalties and interest charges can quickly add up, creating an unnecessary financial burden. Filing late also delays refunds and may trigger closer scrutiny from tax authorities.
Can Startups and LLPs File Belated Returns?
Startups and LLPs that miss their original due date for filing income tax returns are not left without recourse, as the law provides the option to file belated returns. A belated return is essentially a return filed after the prescribed deadline under Section 139(4) of the Income Tax Act. For the financial year 2024-25 (assessment year 2025-26), the last date to file a belated return is December 31, 2025. While this provision gives businesses an extended window to stay compliant, it does come with certain consequences.
Filing a belated return attracts penalties under Section 234F, which can go up to Rs. 5,000 if the total income exceeds Rs. 5 lakh, and Rs. 1,000 for incomes below this threshold. In addition to fixed penalties, taxpayers may also be liable to pay interest on outstanding tax dues under Section 234A at the rate of 1 per cent per month until the return is filed and the tax is paid. These costs can add up quickly, making delayed filing more expensive than meeting the original deadlines.
Another important limitation of belated returns is the loss of certain benefits. For example, businesses that incur losses under the head of business or capital gains may not be allowed to carry these losses forward to subsequent years if the return is filed late. This can significantly affect startups and LLPs that rely on loss carry-forward provisions to reduce their tax liability in future profitable years. Refunds are also delayed in belated filings, which impacts cash flow management for small and growing enterprises.
Apart from belated returns, the Income Tax Act also allows taxpayers to file an updated return, known as ITR-U, introduced under Section 139(8A). This facility is particularly useful for those who have already filed a return but later discover income that was omitted or errors that need rectification. Updated returns can be filed within two years from the end of the relevant assessment year, giving startups and LLPs more time to correct past mistakes. However, filing an ITR-U generally involves paying additional taxes along with interest and fees, depending on the extent of the correction.
In practical terms, while both belated and updated returns serve as important compliance tools, they should be seen as a fallback option rather than a preferred approach. Timely filing ensures that penalties are avoided, refunds are processed sooner, losses can be carried forward, and credibility with investors, lenders, and regulators remains intact. For startups and LLPs working in competitive and regulated environments, adhering to deadlines is not only about legal compliance but also about building financial trust and long-term sustainability.
Importance of Timely ITR Filing for Compliance and Funding
Filing income tax returns within the stipulated deadlines carries far more significance than simply avoiding late fees or interest charges. It reflects a company’s commitment to transparency and accountability, both of which are highly valued in today’s business environment. When returns are filed on time, it creates a reliable financial record that can be referred to by regulators, banks, and potential investors. This record demonstrates that the business is serious about compliance and operates with financial discipline.
For startups, timely ITR filing often becomes a deciding factor when approaching venture capital firms, angel investors, or financial institutions for funding. Investors carefully evaluate a startup’s compliance history before committing capital, as tax irregularities or missed deadlines raise concerns about risk management and long-term stability. Government incentives and tax benefits aimed at startups are also conditional upon timely filing, which means delays could lead to missed opportunities that might otherwise ease cash flow or reduce tax liabilities.
For LLPs, which function as professional partnerships, the importance of punctual filing extends beyond investors to include clients and statutory authorities. Clients seeking long-term relationships with professional firms often assess credibility and reputation, and a consistent record of timely compliance adds to the firm’s professional standing. Furthermore, timely returns ensure that partners can declare accurate income, avoid disputes over tax liabilities, and maintain clarity in profit-sharing. Regulatory authorities, including the Ministry of Corporate Affairs, also cross-check tax compliance records, which makes punctual filing a safeguard against legal or administrative complications.
Another important aspect is the impact on cash flow. Income tax refunds, where applicable, are processed only after returns are filed and verified. Filing on time ensures that refunds are released quickly, improving liquidity and allowing businesses to reinvest in growth initiatives. Delays in filing, on the other hand, defer refunds, strain working capital, and in some cases create avoidable borrowing costs.
Overall, timely filing of income tax returns is not a mere procedural requirement. It is a strategic practice that enhances a business’s reputation, secures smoother access to credit and investment, strengthens operational efficiency, and ensures that both startups and LLPs remain in good standing with tax and corporate regulators.

FAQs
Q1. Does TaxBuddy offer both self-filing and expert-assisted plans for ITR filing, or only expert-assisted options?
TaxBuddy provides flexibility for taxpayers by offering both self-filing and expert-assisted plans. In the self-filing option, startups, LLPs, and individuals can upload their documents such as Form 16, bank statements, or TDS certificates, and the AI-driven platform auto-fills relevant details, performs error checks, and ensures accuracy before submission. For those who prefer guidance or have complex returns involving audits, capital gains, or multiple income heads, the expert-assisted plan connects users with trained professionals who prepare, review, and file the return while also providing post-filing support in case of notices or clarifications from the Income Tax Department.
Q2. Which is the best site to file ITR?
The official Income Tax e-filing portal is the primary site for filing ITRs. However, many taxpayers prefer using platforms that simplify the process and reduce errors. TaxBuddy is considered among the best platforms due to its AI-powered system, which streamlines filing by pulling data from PAN and Aadhaar, cross-verifying TDS details, and reducing manual effort. It also offers notice-handling support, something that traditional filing portals do not provide, making it a more comprehensive solution for startups, LLPs, and individuals with complex filing needs.
Q3. Where to file an income tax return?
Income tax returns can be filed directly on the official Income Tax Department website. Alternatively, taxpayers can use reliable platforms like TaxBuddy, which integrates directly with the department’s systems but adds layers of convenience such as automated data entry, real-time validation, and professional review. For startups and LLPs, using a platform like TaxBuddy reduces compliance risks while ensuring deadlines are met without stress.
Q4. Is ITR filing mandatory for startups with no income?
Yes, filing an ITR is mandatory for startups even if they have zero income or are operating at a loss. This requirement ensures the entity remains compliant under the Income Tax Act, 1961. Filing returns also helps startups build a credible financial track record, which is essential for securing funding, opening business bank accounts, applying for government schemes, or even claiming tax benefits in future years. Non-filing can attract penalties and complicate regulatory filings later.
Q5. What is the ITR filing deadline for startups in 2025?
For the financial year 2024-25 (assessment year 2025-26), the deadline for startups not subject to audit is September 16, 2025, extended by a day from September 15 due to technical issues with the portal. For startups that require an audit, such as those crossing turnover thresholds or falling under specific compliance conditions, the deadline is October 31, 2025. Any delay beyond these dates may invite penalties and interest under Sections 234F and 234A of the Income Tax Act.
Q6. What is the ITR filing deadline for LLPs in 2025?
For LLPs not subject to audit, the ITR filing deadline is July 31, 2025. LLPs that meet the audit requirement—those with turnover above Rs. 40 lakh or partner contributions exceeding Rs. 25 lakh—must file their returns by September 30, 2025. Additionally, LLPs are required to file Form 8 (Statement of Account and Solvency) with the Ministry of Corporate Affairs by October 30 every year, making compliance stricter than for individual taxpayers.
Q7. Which ITR form should LLPs file?
LLPs must use ITR-5, the designated form for partnership firms, LLPs, and certain other entities. This form is specifically structured to capture partnership-related financial details, including business income, capital contributions, and profit-sharing ratios among partners. Unlike individuals who may use ITR-1, ITR-3, or ITR-4 depending on their income sources, LLPs are restricted to ITR-5. Filing any other form can lead to rejection or legal complications.
Q8. Can startups and LLPs file belated returns if they miss the deadline?
Yes, belated returns are permitted under Section 139(4) of the Income Tax Act. For FY 2024-25, startups and LLPs can file belated returns until December 31, 2025. However, belated returns carry penalties and interest, and taxpayers may lose certain benefits such as the ability to carry forward losses. Filing late also delays refunds and increases the chances of tax scrutiny, making timely filing the more prudent approach.
Q9. What penalties apply for late ITR filing?
Under Section 234F, taxpayers with income above Rs. 5 lakh face a penalty of up to Rs. 5,000 for late filing. For those with an income below Rs. 5 lakh, the penalty is Rs. 1,000. In addition to these fixed penalties, Section 234A imposes interest at 1% per month on any unpaid tax liability until the return is filed. This combination of penalties and interest can significantly increase costs for startups and LLPs, making delays financially risky.
Q10. What happens if startups or LLPs fail to file ITR?
Non-filing of ITR can result in multiple consequences. Financially, taxpayers may face penalties and interest. Legally, it can lead to notices from the Income Tax Department. For startups, failure to file hampers credibility with investors, banks, and regulators. LLPs may face additional compliance issues with the Ministry of Corporate Affairs, which requires financial statements supported by timely ITRs. In severe cases, continued non-compliance can trigger prosecution under the Income Tax Act.
Q11. Can updated returns be filed later?
Yes, the Income Tax Act now allows taxpayers to file an updated return (ITR-U) under Section 139(8A). This facility enables startups and LLPs to correct errors, disclose additional income, or rectify missed details up to two years from the end of the relevant assessment year. However, filing an updated return comes with additional tax and penalty implications, depending on the nature of the correction. It is a safety net, but not a substitute for timely filing.
Q12. How does TaxBuddy simplify ITR filing for startups and LLPs?
TaxBuddy combines automation with professional expertise to make compliance stress-free. Its AI-driven system fetches and auto-fills data from PAN, Aadhaar, and Form 16, minimising manual input errors.
