Who has to pay advance tax?

Anyone whose net tax liability for the year (after TDS/TCS) is ₹10,000 or more. A resident senior citizen with no business or professional income is exempt. Presumptive taxpayers (44AD/44ADA) pay the whole amount by 15 March.

What if I miss an instalment?

Interest u/s 234C runs at 1% per month for the shortfall period (with 12%/36% safe harbours for the first two instalments), and u/s 234B at 1% per month from April if less than 90% of the liability is paid by 31 March. Capital gains and windfalls arising after an instalment date can be paid in the remaining instalments without 234C interest.
