Income Tax Penalties and Prosecution: Sections 439 Onwards

The Income-tax Act enforces compliance in two ways. Penalties are civil consequences imposed by tax authorities for under-reporting income or failing to comply with procedural duties. Prosecution is criminal: courts may imprison and fine those who wilfully evade tax, fail to file returns or make false statements. The Finance Act, 2026 softened both sides of this scheme. This note covers the main penalties and offences under the Income-tax Act, 2025 as amended.

1. Under-reporting and Misreporting: Section 439

• Penalty. Where income is under-reported, a penalty of 50 per cent of the tax payable on the under-reported income may be levied; where the under-reporting is in consequence of misreporting, the penalty is 200 per cent (old s.270A)
• Under-reporting. Covers cases such as assessed income exceeding returned income, or income assessed where no return was filed.
• Immunity, s.440. Immunity from penalty and prosecution is available where the assessee pays the tax and interest within the time allowed and does not appeal (old s.270AA); from 1 April 2026 it extends to penalty for misreporting as well.
• In the assessment order. From 1 April 2026, the penalty for under-reporting is imposed in the assessment order itself rather than in separate proceedings.
• Not automatic. In CIT v Reliance Petroproducts (2010), decided under the earlier concealment penalty, the Supreme Court held that a mere claim that is not accepted does not by itself amount to furnishing inaccurate particulars.

The 2025 Act also penalises failure to keep books and documents (s.441), false or omitted entries in books (s.444), failure to deduct or pay tax at source (s.448) and to collect it (s.449), and non-compliance with summons and notices (s.465). A person in default of tax payable may also face a penalty up to the tax in arrears (s.412). The Finance Act, 2026 converted the penalties for failure to get accounts audited (s.446), failure to furnish an accountant's report (s.447) and default in statements of financial transactions (s.454) into graded fees from 1 April 2026.

3. Prosecution and the 2026 Decriminalisation

Figure 3: Main offences (1961 Act numbering)

• Finance Act, 2026. In Chapter XXII of the 2025 Act (ss.473 to 485 and 494), rigorous imprisonment became simple imprisonment, the maximum term fell from seven years to two (three for repeat offences), fines were added or substituted, offences where tax evaded is up to Rs 10 lakh became punishable with fine only, and some offences were decriminalised, from 1 April 2026.
• Wilful evasion (old s.276C). A wilful attempt to evade tax, penalty or interest remains an offence, now within the reduced scale of punishment.
• Failure to file a return (old s.276CC). Wilful failure to furnish a return in time remains an offence, graded by the tax involved.
• Tax at source (old ss.276B, 276BB). Failure to pay to the Government tax deducted or collected at source is punishable.
• False verification (old s.277). Making a false statement in a verification or delivering a false account is punishable.
• Culpable mental state (old s.278E). The court presumes the existence of a culpable mental state, and the accused must prove its absence beyond reasonable doubt.
• Sasi Enterprises v ACIT (2014). The Supreme Court held that prosecution for wilful failure to file returns can proceed independently of pending assessment proceedings, and that the presumption of culpable mental state applies.

4. Frequently Asked Questions
