Penalties, in the context of Indian taxation, are punitive charges imposed by the Income Tax Department on taxpayers who fail to comply with tax law requirements — including non-filing of returns, under-reporting of income, inaccurate disclosures, wilful tax evasion, failure to deduct or deposit TDS, and various other specified violations under the Income Tax Act, 1961. Key penalty provisions include: Section 234A (interest for delay in filing return — 1% per month on outstanding tax), Section 234B and 234C (interest for shortfall in advance tax payments), Section 270A (penalty for under-reporting of income — 50% of the under-reported tax; 200% for misreporting), Section 271(1)(b) (penalty for failure to comply with statutory notices — ₹10,000 per failure), and Section 276C (prosecution for wilful tax evasion — rigorous imprisonment of 6 months to 7 years). For SEBI-related penalties, violations of securities market regulations — insider trading, fraudulent trading, non-disclosure of shareholding changes, and RPT non-compliance — attract monetary penalties of up to ₹25 crore or three times the profit made, along with disgorgement orders and trading bans. For Indian investors, understanding penalty provisions helps in proactive compliance — filing returns on time, accurately reporting all income sources including capital gains, dividends, and foreign income, and ensuring TDS obligations are met on payments to contractors, professionals, and rent recipients above specified thresholds.
