If your tax liability after TDS crosses ₹10,000 in a year, the law expects you to pay it in four instalments rather than in one lump at the end. Missing them costs 1% a month.
The schedule
15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March — each figure cumulative, not incremental. The calculator converts them into what you actually transfer on each date.
Who needs to bother
Salaried people whose employer deducts enough TDS usually have nothing left to pay. Advance tax becomes real when you have rental income, capital gains, interest income, freelance receipts or a business. Senior citizens without business income are exempt from advance tax entirely.
Capital gains are the awkward case
You cannot forecast a gain you have not made. The law accepts this: a gain that arises after an instalment date can be paid in the next one without attracting 234C interest on the earlier shortfall.
Frequently asked questions
Who has to pay advance tax?
Anyone whose tax liability after TDS exceeds ₹10,000 in a financial year. In practice that means people with rental income, capital gains, interest income, freelance receipts or business income. Resident senior citizens without business income are exempt.
What happens if I miss an instalment?
Section 234C charges 1% a month for three months on the shortfall in each instalment. Section 234B adds 1% a month from April until payment if you have paid less than 90% of the total liability by 31 March.
How do I handle capital gains I could not predict?
The law accepts that a gain cannot be forecast. Tax on a gain arising after an instalment date can be paid in the next instalment, or by 31 March for a gain in the final quarter, without attracting 234C interest on the earlier shortfall.
Can I pay the whole amount in one go?
You can, but interest applies to the instalments you skipped along the way. Paying everything in March does not avoid 234C on the June, September and December shortfalls.
