EaseValueChapter XXI of the Income-tax Act, 2025 sets out the penalties for non-compliance. The most significant is the penalty for under-reporting and misreporting of income — broadly 50% of the tax on under-reported income and up to 200% for misreporting — the successor to Section 270A.
Other penalties cover TDS/TCS defaults, failure to maintain or audit accounts, late filing, and non-response to notices. Many penalties can be reduced or dropped where there is a reasonable cause, which is why a proper reply matters.
See the sections below for each penalty, and ask in the discussion if a penalty has been proposed against you.
