✅ Verified: Income-tax Act 2025 Sections 400–420 | incometax.gov.in | CBDT Circulars

Penalty is the most feared outcome of a tax assessment — and the most misunderstood. The Income-tax Act 2025 consolidates and renumbers penalty provisions originally scattered across Sections 271 to 275B of the old Act. The rates are unchanged, but the section numbers are new, the immunity routes have been clarified, and the faceless penalty framework is now formally codified. This guide maps every key penalty section, explains what triggers each, and shows how to respond or seek immunity.

Under-Reporting vs Misreporting — Critical Distinction

The distinction between under-reporting and misreporting determines whether the penalty is 50% or 200% of tax. This is the single most important distinction in the penalty chapter:

Under-Reporting (50% Penalty) — Triggers

Misreporting (200% Penalty) — Triggers

🚨
200% Penalty Is Not Negotiable Downward: If the AO classifies an addition as "misreporting," the penalty is mandatorily 200% — there is no discretion to impose a lower rate. This is why taxpayer responses to assessment must never admit to suppression or fraud — distinguish the case clearly as a bona fide interpretation difference (under-reporting) if that is the true characterisation.

Case Study: How One Word Cost ₹18 Lakh in Penalty

Textile Trader, Surat — AY 2023-24

Harish, a fabric trader, made a cash purchase of ₹9 lakh that he couldn't explain to the AO's satisfaction. During the assessment, his accountant, trying to cooperate, said in a written submission: "the entry was made in the books but the purchase was bogus." The AO used this to classify the addition as "misreporting" under Section 270A(9) (old Act), triggering 200% penalty.

Tax on ₹9L Addition
₹3.15 lakh (35% slab + cess)
Penalty at 200%
₹6.30 lakh

Total outgo: ₹9.45 lakh — more than the original unexplained amount itself. Had the accountant characterised the matter as an unsubstantiated purchase (under-reporting), the 50% penalty would have been ₹1.575 lakh — saving ₹4.73 lakh in penalty alone.

Lesson: Every word in a written response to the AO matters. Never admit to false entries, bogus claims, or suppression — always characterise additions as bona fide interpretation differences or lack of evidence.

Immunity from Penalty — When You Can Escape

Under Section 404 of the new Act (old Section 270A), penalty is not leviable in the following cases:

Faceless Penalty Proceedings — How They Work

The Faceless Penalty Scheme (FPS) was launched under the old Act and is now formally part of the new Act under Section 403. Key features:

Penalty for TDS Non-compliance

TDS-related penalties remain one of the most common penalty triggers for businesses:

TDS DefaultOld SectionNew SectionPenalty
TDS not deducted271C407100% of TDS amount not deducted
TDS deducted but not deposited271C407100% of TDS amount not deposited
Late filing of TDS return (26Q/24Q)271H412₹10,000 to ₹1 lakh
Incorrect PAN in TDS return272B421₹10,000 per incorrect PAN
⚠️
TDS Penalty Has No Immunity Route: Unlike the under-reporting penalty (which has immunity if the taxpayer accepts and pays), TDS non-deduction penalty under Section 407 has very limited escape routes. The only defence is that the payment was not chargeable to TDS under the law, or that deduction was made and deposited with a bona fide reasonable belief.

Penalty Response Checklist

  • Read the penalty notice carefully — identify which section and which addition is the basis
  • Never admit suppression, false entry, or bogus claim in written response
  • Characterise any addition as: bona fide interpretation difference or lack of evidence (never fraud)
  • If considering accepting assessment, file immunity application within 1 month under Section 404(7)
  • For TDS penalty: check if the transaction genuinely attracted TDS obligation before conceding
  • Respond within the time given in the show-cause notice — penalty is automatic if no response
  • Appeal against penalty order within 30 days if immune application is rejected

Frequently Asked Questions

Under Section 404 of the Income-tax Act 2025 (old Section 270A), the penalty for under-reporting of income is 50% of the tax payable on the under-reported income. For misreporting — which involves false entries, suppression of facts, or fraudulent claims — the penalty is 200% of the tax. The AO must pass a separate penalty order and give the taxpayer an opportunity to respond before the penalty is levied.
Under Section 404(7) of the Income-tax Act 2025, if you accept the assessment order (without filing an appeal) and pay the entire tax and interest within the prescribed time, you can file an immunity application within 1 month. If immunity is granted, the 50% under-reporting penalty is waived. For 200% misreporting penalty, immunity is not available through this route — it requires either the Vivad Se Vishwas scheme or a successful appeal proving there was no misrepresentation.
No. A penalty is not automatic. The Assessing Officer must separately initiate penalty proceedings, issue a show-cause notice (SCN) to the taxpayer, and pass a penalty order after considering the taxpayer's response. The SCN gives you an opportunity to explain why penalty should not be levied — a bona fide reason (like a genuine interpretation dispute or documentation gap) can result in penalty being waived.
