CFP Note on Penalty Avoidance
Advance tax is a "pay-as-you-earn" obligation. Missing a due date triggers 234C interest at 1% per month on the shortfall — this cannot be avoided even if you pay the full amount later. Set calendar reminders for all four dates (15 Jun / 15 Sep / 15 Dec / 15 Mar). For business income, review your estimate each quarter and top up if income has risen — a small overpayment is always cheaper than 234B/234C interest.
