2-Minute Analysis: The Difference Between a Mistake and a Crime

In tax law, there is a clear distinction between making an honest mistake and deliberately hiding income. The Act treats them very differently.

An honest mistake, such as forgetting to include bank interest income, can result in a penalty of 50% of the tax on that income. A deliberate act, such as maintaining false entries or suppressing material facts, attracts 200% of the tax. And if the evasion is large enough, it means imprisonment.

Here is a simple mental model with three levels:

Level 1, Procedural default: You filed late, missed a deadline, or did not furnish a required report. These attract flat fees.
Level 2, Under-reporting income: Your income as assessed is higher than what you declared. Penalty is 50% of the tax on the difference.
Level 3, Misreporting income: You actively suppressed facts, recorded false entries, or made false claims. Penalty is 200% of the tax. At large amounts, prosecution follows.

Penalty for Under-Reporting and Misreporting of Income

Section 439 of the Income Tax Act, 2025 (corresponding to Section 270A of the Income Tax Act, 1961) is the primary penalty provision.

What is Under-Reporting?

You are deemed to have under-reported your income when [Section 439(2)]:

Income assessed is greater than income shown in your processed return
You did not file a return and income assessed exceeds the basic exemption limit
Income reassessed is greater than income previously assessed
The assessment reduces a declared loss or converts it into income

Penalty: 50% of Tax on Under-Reported Income

Section 439(9) prescribes a penalty of 50% of the tax payable on the under-reported income.

Example: Rajan declared business income of Rs. 8 lakh. During assessment, the officer adds Rs. 2 lakh as unaccounted cash receipts, a sum not recorded but identifiable from third-party data. Tax on Rs. 2 lakh at 20% = Rs. 40,000. Penalty = 50% x Rs. 40,000 = Rs. 20,000. This is in addition to the tax of Rs. 40,000.

What is Misreporting? (200% Penalty)

Sections 439(10) and 439(11) prescribe a 200% penalty where under-reporting is a consequence of misreporting. The Act identifies the following specific acts as misreporting:

Act Constituting Misreporting	Practical Example
Misrepresentation or suppression of facts	Claiming a non-existent expense or denying a receipt
Failure to record investments in books	Acquiring an asset and not entering it in accounts
Claim of expenditure without substantiating evidence	Showing contractor payments with no supporting bills
Recording false entries in books	Inflating expenses with fabricated invoices
Failure to record receipts affecting total income	Cash sales received but not entered in books
Failure to report international or specified domestic transactions under Chapter X	Transfer pricing transactions not disclosed
Income referred to in Section 195(1)(b) as inserted by Finance Act, 2026	Specific category of income under that provision

Example: Sunita’s company shows Rs. 10 lakh in consulting expenses backed by fake invoices. The officer disallows the entire amount. Tax on Rs. 10 lakh at 30% = Rs. 3 lakh. Penalty = 200% x Rs. 3 lakh = Rs. 6 lakh. The original Rs. 3 lakh tax is also due. Total outflow on that single disallowance: Rs. 9 lakh.

When is Penalty NOT Levied?

Section 439(8) provides important exceptions. No penalty applies when:

The assessee offers a bona fide explanation and has disclosed all material facts to substantiate it
The under-reporting is based on an estimate, the books are correct and complete, but the accounting method does not permit precise income computation
The assessee made a lower estimate on his own, included it in the return, and disclosed all material facts relevant to the issue

These exceptions protect honest taxpayers who made genuine estimation errors with full transparency.

Late Filing Fee and Other Procedural Fees

Late Filing Fee (Section 428(a), corresponding to Section 234F of the 1961 Act)

Miss the ITR due date and a fee is payable before filing:

Rs. 1,000 if total income does not exceed Rs. 5,00,000
Rs. 5,000 in any other case

This applies when filing a belated return under Section 263(4).

Section 428(b) also prescribes the same fee (Rs. 1,000 or Rs. 5,000) if you furnish a revised return under Section 263(5) beyond nine months from the end of the relevant tax year.

Fee for Not Getting Accounts Audited (Section 428(c), corresponding to Section 271B of the 1961 Act)

If you were required to get accounts audited under Section 63 but failed to do so and furnish the audit report, you pay:

Rs. 75,000 for a delay up to one month
Rs. 1,50,000 for a delay beyond one month

Under Section 271B of the Income Tax Act, 1961, the penalty was the lesser of 0.5% of turnover or Rs. 1,50,000. The new Act restructures this as a time-based fee. The maximum cap stays at Rs. 1,50,000, but a Rs. 75,000 slab now applies for shorter delays.

Penalty for Non-Compliance with Information Requirements

Failure	Penalty
Failure to furnish required information or documents	Rs. 25,000 per instance [Section 441]
Failure to report transfer pricing or specified domestic transactions	2% of transaction value [Section 442]

Prosecution: When Non-Compliance Becomes Criminal

Prosecution converts a tax matter into a criminal proceeding. It is reserved for wilful conduct, not honest mistakes.

Tax Evasion (Section 478, corresponding to Section 276C of the 1961 Act)

If a person willfully attempts in any manner to evade any tax, penalty, or interest, or under-reports income:

Amount Sought to Be Evaded	Punishment
Exceeds Rs. 50 lakh	Simple imprisonment up to 2 years, or fine, or both
Rs. 10 lakh to Rs. 50 lakh	Simple imprisonment up to 6 months, or fine, or both
Any other amount	Fine only

Section 478(4) clarifies that wilful evasion includes: possessing books with false entries, making false entries, wilfully omitting relevant entries, or causing circumstances that enable evasion.

Finance Act, 2026 change: The original Section 478 prescribed rigorous imprisonment with minimum terms (minimum 6 months up to 7 years for evasion above Rs. 25 lakh). The Finance Act, 2026 substituted this with simple imprisonment (up to 2 years) with no mandatory minimum, introduced a new Rs. 10 to Rs. 50 lakh slab, and raised the higher slab threshold from Rs. 25 lakh to Rs. 50 lakh.

Wilful Failure to File Return (Section 479, corresponding to Section 276CC of the 1961 Act)

If you wilfully fail to furnish a return required under Section 263(1) or by notice under Section 268(1) or 280:

Tax Evasion Amount	Punishment
Exceeds Rs. 50 lakh	Simple imprisonment up to 2 years, or fine, or both
Rs. 10 lakh to Rs. 50 lakh	Simple imprisonment up to 6 months, or fine, or both
Any other case	Fine only

Protected from prosecution if [Section 479(2)]:

You subsequently file a belated return under Section 263(4) or an updated return under Section 263(6), or
The net tax payable, after advance tax, self-assessment tax paid before the belated return deadline, and TDS, does not exceed Rs. 10,000

This protection covers most small taxpayers who simply forgot to file, as long as they file eventually.

Waiver of Penalty and Immunity from Prosecution

Section 440 of the Income Tax Act, 2025 (corresponding to Section 270AA of the 1961 Act, as substituted by Finance Act, 2026) provides a path to close the matter without prosecution. You can apply to the Assessing Officer for waiver of penalty under Section 439 and immunity from prosecution under Sections 478 and 479, if:

(a) Tax and interest under the assessment order have been paid in full within the notice of demand period

(b) Additional income-tax has been paid in lieu of penalty:

For misreporting under Section 439(11)(a) to (f): Pay 100% of the tax payable on the under-reported income in lieu of the penalty
For misreporting under Section 439(11)(g): Pay 120% of the tax payable on the under-reported income in lieu of the penalty

Clarification on the numbers: The penalty for misreporting is 200% of the tax on under-reported income. The immunity route replaces that penalty with an additional tax of 100% (or 120%) of the same underlying tax. So if tax on misreported income is Rs. 3 lakh: the penalty would have been Rs. 6 lakh, but paying Rs. 3 lakh as additional tax (100% of the underlying tax) settles the matter and bars prosecution entirely.

The application must be filed within one month from the end of the month in which the assessment order is received [Section 440(2)].

Wilful tax evasion above Rs. 50 lakh	Simple imprisonment up to 2 years, plus fine
Wilful failure to file above Rs. 50 lakh	Simple imprisonment up to 2 years, plus fine
Immunity route (misreporting, (a)-(f))	Pay 100% of tax on under-reported income; penalty waived, prosecution barred

Practical Compliance Checklist

If you made an honest error in a past return: File an updated return under Section 263(6) and pay the applicable additional tax (25% to 70% depending on timing). Proactive correction before any notice is issued protects you from penalty and prosecution.
If you are facing a proposed addition during assessment: Determine whether the addition arises from under-reporting or misreporting. If it is a genuine estimation difference with full disclosure, push back on any attempt to charge 200%. The correct rate for honest discrepancies is 50%.
If you have previously misreported income and the department has not yet acted: Consider proactive disclosure via updated return. Once a notice under Section 280 or a search is initiated, that window closes permanently.
If a penalty order is received and you want to avoid prosecution: Evaluate Section 440. Pay the full assessed tax, interest, and the 100% (or 120%) additional tax within the notice of demand period. File the immunity application within one month of receiving the assessment order. Do not file an appeal if you choose this route.

Penalties and prosecutions under the Income Tax Act are not designed to trap honest taxpayers. They exist to deter deliberate evasion. The law is forgiving of genuine errors made transparently and corrected promptly. It is severe only when the intent to evade is clear. Keep your records accurate, file on time, and respond honestly to any notice, and the prosecution chapter of this Act will never be relevant to you.
