If your tax exceeds 10,000 per year and you skip advance tax, Section 234B and 234C interest applies.
Advance tax is 'pay as you earn' — if your total tax liability for the year exceeds ₹10,000, you must pay it in installments through the year.
Who Must Pay
Any individual, HUF, or business whose total tax liability exceeds ₹10,000 in a financial year must pay advance tax. Salaried employees typically don't need to worry if their employer deducts sufficient TDS.

| 15 December | Up to 75% | Up to 75% |
| 15 March | Up to 100% | — |

Interest under Section 234C: 1% per month on shortfall. Under Section 234B: 1% per month if less than 90% of total tax is paid by 31 March.
