This article covers Indian income-tax law. Under-reporting is the statutory threshold category; misreporting is a defined subset that can trigger the higher penalty. Under the Income-tax Act, 1961, the general penalty is 50% of the tax payable on under-reported income, rising to 200% when that under-reporting results from misreporting—not 50% or 200% of the income itself. For cases governed by the Income-tax Act, 2025, the successor rule is in section 439. Which Act applies depends on the relevant tax year and transition provisions.
What is the difference?
Under-reporting describes income that meets statutory tests comparing a return, assessment or reassessment. Misreporting is not simply another name for an income discrepancy: it is under-reported income connected to one or more specified forms of conduct. The distinction matters because the 1961 Act sets a higher penalty rate when under-reporting is in consequence of misreporting.

Under section 270A of the Income-tax Act, 1961, the penalty is generally 50% of the tax payable on under-reported income. If that under-reporting is in consequence of misreporting, the rate is 200% of that tax. The tax base is the tax payable on the under-reported income, not the amount of income itself. See the Income Tax Department’s guidance on penalties.
How does the 1961 Act identify under-reported income?
Section 270A(2) sets out circumstances in which income is treated as under-reported. These include, among others, assessed income exceeding the amount determined in a return processed under section 143(1)(a), income above the maximum amount not chargeable to tax in specified no-return cases, an increase in income on reassessment, certain comparisons involving deemed income, and an assessment that reduces a declared loss or converts a loss into income.
#1 Best Overall
The amount of under-reported income is subject to statutory calculation rules. It should not be assumed to equal the gross difference between a return and an assessment in every case. The governing text is section 270A of the Income-tax Act, 1961.
What counts as misreporting under section 270A?
For cases under the 1961 Act, section 270A(9) lists six forms of misreporting. Whether particular facts fit one of them depends on the evidence and the applicable statutory requirements.
Rank #2
- Misrepresentation or suppression of facts.
- Failure to record investments in the books of account.
- A claim of expenditure that is not substantiated by evidence.
- Recording a false entry in the books of account.
- Failure to record a receipt that has a bearing on total income.
- Failure to report specified international or domestic transactions governed by Chapter X.
An assessment adjustment or an error in a return does not, by itself, establish that the higher misreporting rate applies. The under-reported income must be in consequence of a listed category for that higher rate to be relevant.

When can an amount be excluded?
Section 270A(6) excludes specified situations from under-reported income. One example is where the taxpayer offers an explanation, the authority is satisfied that it is bona fide, and all material facts have been disclosed. The section also addresses specified estimates, certain transfer-pricing adjustments subject to documentation and disclosure conditions, and undisclosed income dealt with under another provision.
An explanation does not automatically prevent a penalty. The statutory conditions must be met, and the authority’s satisfaction is part of the test. The facts and any other applicable exclusions need to be considered in the particular case.
Which Act applies after 1 April 2026?
The Income-tax Act, 2025 came into force on 1 April 2026, and its successor penalty provision is section 439. The amended 2025 Act text provides a 200% rate for misreporting and includes a category added by the 2026 amendments. Do not carry section 270A’s six-item list across as though it exhausts the categories under every case governed by the 2025 Act.

- Identify the governing law. Check the tax year, the Act cited in the notice, and any relevant commencement or transition rules.
- Check the statutory basis for under-reporting. Read the comparison and calculation used in the assessment or reassessment; do not assume the gross adjustment is automatically the penalty base.
- Check the alleged misreporting category. If the higher rate is proposed, identify which statutory category is alleged and how the facts are said to fit it.
- Review exclusions and supporting records. Consider whether a statutory exclusion may apply and gather the return, books, supporting evidence, disclosures and assessment documents relevant to its conditions.
- Get case-specific advice where needed. A chartered accountant or India-focused tax adviser can assess the notice, calculations, applicable provisions and response deadlines.
A printed Act or annotated reference can be useful, but check that its edition contains amendments applicable to the relevant tax year. The official online statute is the reference for the current text.
