The Income Tax Act, 1961 contains over 40 penalty provisions — a dense web of consequences for various types of non-compliance, from simple failures to file returns to deliberate tax evasion. Most taxpayers discover which penalty applies to them only after receiving a penalty notice. By then, the opportunity to minimise the penalty by voluntary compliance may have already passed.
This guide decodes every major penalty provision — what triggers it, how much it is, and what defences are available.
Section 270A — Penalty for Under-Reporting or Misreporting of Income
Section 270A was introduced in 2016 to replace Section 271(1)(c). It creates two distinct categories of default with very different penalty rates:
Under-Reporting of Income
What it covers: Income assessed by the AO exceeds income declared by the taxpayer — i.e., the AO makes an addition to income.
Penalty rate: 50% of tax on the under-reported income.
Defence available: If the taxpayer can show that the addition was based on a bona fide dispute on a question of law or fact, penalty may not be levied. Penalty is not automatic on mere addition — the AO must satisfy themselves that the under-reporting was deliberate.
Misreporting of Income
What it covers: Misrepresentation or suppression of facts, failure to record investments in books, claim of false expense, false entry in books, failure to report international transactions at arm's length, or income in excess of loan from unregistered parties.
Penalty rate: 200% of tax on the misreported income — four times the under-reporting rate.
No defence: Misreporting penalties are nearly absolute — the AO has limited discretion once misreporting is established.
Section 271 — The Old Penalty Provision (Still Applicable for Pre-AY 2017-18 Cases)
Section 271(1)(c) — penalty for concealment of income or furnishing inaccurate particulars — continues to apply for assessment years prior to AY 2017-18. The penalty is 100% to 300% of tax on concealed income. Based on the Supreme Court's ruling in Reliance Petroproducts, mere addition of income does not automatically warrant penalty — the AO must prove deliberate concealment.
Section 271A — Non-Maintenance of Accounts
Trigger: Failure to keep and maintain books of accounts as required under Section 44AA.
Penalty: ₹25,000 fixed penalty.
Who must maintain accounts: Professionals (doctors, lawyers, CAs, engineers) with gross receipts above ₹1.5 lakh; businesses with turnover above ₹25 lakh (or ₹10 lakh for certain professionals) in any 3 of the past 5 years.
Section 271AA — Failure to Maintain Transfer Pricing Documentation
Trigger: Failure to maintain prescribed transfer pricing documentation under Rule 10D, or failure to report international transactions, or maintaining incorrect documentation.
Penalty: 2% of the value of each international transaction or specified domestic transaction for which documentation is not maintained.
Section 271AAA — Penalty in Search Cases (Pre-1 June 2016)
Trigger: Income found during search (Section 132) that has not been disclosed in any return.
Penalty: 10% of undisclosed income — significantly lower than Section 271(1)(c) to encourage disclosure during search.
Section 271AAB — Penalty in Search Cases (Post-1 June 2016)
Trigger: Undisclosed income found during search assessment.
Penalty rates: 30% of undisclosed income admitted and taxes paid during search; 60% of undisclosed income not admitted during search.
Key takeaway: During a search operation, admitting undisclosed income and paying tax on it before the search concludes reduces penalty from 60% to 30%.
Section 271B — Failure to Get Accounts Audited
Trigger: Failure to get accounts audited under Section 44AB where turnover exceeds ₹1 crore (₹2/3 crore for digital transactions) or professional receipts exceed ₹50 lakh.
Penalty: 0.5% of turnover/gross receipts or ₹1.5 lakh — whichever is less.
Section 271C — Failure to Deduct TDS
Trigger: Failure to deduct tax at source where required, or failure to pay TDS after deduction.
Penalty: Equal to the amount of TDS not deducted or not paid — i.e., 100% of the TDS amount.
Note: This penalty is in addition to interest under Section 201 and disallowance of expense under Section 40(a)(ia).
Section 272A — Non-Compliance with Notices
Trigger: Failure to comply with notices under Sections 94(6), 94A, 115TC, 131, 133, 133B, 133C, 134, 139(4A), 139(4B), 139(4C), 139(4D), 142, 143(2), or 148.
Penalty: ₹10,000 for each failure. Can be levied multiple times — one for each notice not complied with.
Section 275 — Time Limit for Imposing Penalty
Penalty must be imposed within the prescribed time limits — otherwise it becomes time-barred:
Penalty relating to assessment: 6 months from the end of the month in which penalty proceedings are initiated (or 6 months from end of financial year in which the relevant assessment/order becomes final).
Penalty relating to non-compliance: 6 months from the end of the month in which the penalty is imposed by the competent authority.
Always check time limits when contesting a penalty — many penalties are levied outside the prescribed period and can be challenged on limitation grounds alone.
General Defences Against Income Tax Penalties
Reasonable cause: Section 273B provides that no penalty shall be levied if the taxpayer proves there was reasonable cause for the failure. What constitutes reasonable cause depends on facts — illness, natural disaster, incorrect advice from CA, technical issues on portal.
Bona fide dispute: For Section 270A under-reporting (not misreporting), a genuine dispute on law or facts is a defence.
Voluntary disclosure: Disclosing income before notice reduces penalty in many cases — e.g., Section 271AAB.
Limitation: Penalty beyond the prescribed time limit is void. Always check whether the penalty notice was issued within time.
