Due date to file ITR Soon: What will happen if you miss?

Filing an income tax return is a must for anyone earning in India. It’s how you report your income to the tax department. Who needs to file and the rules depend on whether you’re an individual, company, firm, or other entity. Filing on time is important late or wrong returns can lead to fines or loss of benefits.

Due date of filing of return of income

  • Companies (not required to file Form 3CEB): They must file their income tax return by October 31 of the assessment year. The Due Date was extended to 15th December 2025 for Financial Year 2024-25.
  • Any person or company that must file Form 3CEB (Transfer Pricing cases): They need to file their return by November 30 of the assessment year.
  • Any person (not a company) whose accounts must be audited under Income Tax Law or any other law: Their due date to file the return is October 31 of the assessment year. The Due Date was extended to 15th November 2025 for Financial Year 2024-25.
  • A working partner in a firm whose accounts must be audited: They also must file their return by October 31 of the assessment year. The Due Date was extended to 15th November 2025 for Financial Year 2024-25.
  • All other taxpayers: They must file their return by July 31 of the assessment year.

Belated Return

A belated return is an Income Tax Return (ITR) filed after the original due date has passed. This is permitted under Section 139(4) of the Income Tax Act in India, allowing taxpayers a second chance to meet their compliance obligations, albeit with specific penalties and restrictions. It can be filed at any time three months before the end of the relevant assessment year or before completion of assessment, whichever comes first.

Consequences of delay in filing the return of income

If a person files their income tax return late, there can be several negative results. Here are the main problems that can happen when you delay filing your return:

  • Losses (except house property loss) cannot be carried forward.
  • Interest will be charged for late filing (Section 234A).
  • A late filing fee must be paid (Section 234F).
  • Exemptions under Sections 10A and 10B cannot be claimed.

Penalty

Fee for default in furnishing return of income will be Rs 5,000. However, where the total income of the person does not exceed Rs 500,000 the fee will not exceed Rs 1,000.

Revision of return

Sometimes, while filing an income tax return, a taxpayer may forget to include some information or may make a mistake. If this happens, the taxpayer can correct the error by filing a revised return. A revised return can be filed anytime up to 3 months before the end of the assessment year or before the tax department finishes the assessment, whichever happens first. However, only returns filed on time under Section 139(1) or late returns filed under Section 139(4) can be revised.

Defective Return

Section 139(9) lists the situations where a taxpayer’s income tax return can be considered defective, meaning it has missing information or required documents. If the Assessing Officer finds that a return is defective under this section, then he may ask the taxpayer to correct the mistakes.

The taxpayer must fix the mistakes in the return within 15 days from the date the tax department informs them, or within any extra time the Assessing Officer may give. If the taxpayer does not correct the defect within this time, the return will be treated as invalid, which means it will be considered as not filed at all, and all rules applying to non-filing of return will apply.

A return of income will be regarded as defective unless all the following conditions are met:

  • All parts of the return related to calculating income under different heads, gross total income, and total income must be properly filled in.
  • The return must include a statement showing how the tax payable is calculated.
  • If the taxpayer needs an audit under Section 44AB, the return must include the audit report or proof that it was submitted earlier.
  • The return must include proof of TDS/TCS, advance tax, or self-assessment tax paid; however, if the TDS/TCS certificate was not issued, the return is still valid if the certificate is produced later within the allowed two-year period.
  • If regular books of accounts are maintained, copies of the trading/manufacturing account, profit and loss account, and balance sheet must be attached.
  • Personal accounts of the proprietor, partners, or members must also be attached, depending on the type of business.
  • If the accounts are audited, copies of audited statements and the auditor’s report must be included, along with any cost audit report if applicable.
  • If books of accounts are not maintained, a statement of turnover, gross receipts, profits, expenses, and closing balances of debtors, creditors, stock, and cash must be attached.

Updated Return

An Updated Return (ITR-U) is a special provision under Section 139(8A) of the Indian Income Tax Act that allows a taxpayer to correct errors, disclose omitted income, or file a return if the original and belated deadlines have passed. It offers a final opportunity for voluntary compliance, but it comes with the liability to pay additional tax and cannot be used to claim or increase a refund or report losses.

Filling the return through Tax return Preparers

To help certain groups of people file their income tax returns easily, the government has introduced the Tax Return Preparer (TRP) Scheme. Under this scheme, these people can file their returns with the help of a trained and authorized Tax Return Preparer, who is allowed to assist them in preparing and submitting their returns.

Tax Return Preparer

A Tax Return Preparer (TRP) is a trained person who is officially authorised under the TRPScheme to help people file their income tax returns. However, this person cannot be someone who is already covered under section 288(2)(ii)/(iii)/(iv) such as lawyers or accountants allowed to represent taxpayers or an employee of the person whose return is being filed.

Specified class or classes of person

‘Specified class of persons’ means any taxpayer who has to file an income tax return, except companies and people whose accounts must be audited under Section 44AB or any other law.
