Frequently asked questions
Who must pay advance tax?
Any taxpayer whose estimated tax liability (after TDS) exceeds ₹10,000 in a financial year must pay advance tax. This includes salaried employees with other income (interest, rent, capital gains), freelancers, business owners, and professionals. Senior citizens without business income are exempt.
What are the advance tax due dates?
For all taxpayers (except 44AD/44ADA filers): June 15 — 15%, September 15 — 45%, December 15 — 75%, March 15 — 100%. For businesses under presumptive taxation (44AD/44ADA): entire advance tax by March 15.
What is the penalty for not paying advance tax?
Interest under Section 234B applies at 1% per month if advance tax paid is less than 90% of the assessed tax. Interest under Section 234C applies at 1% per month for each quarter where the cumulative payment is short of the required percentage (15%, 45%, 75%, 100%).
How do I pay advance tax?

Advance tax schedule and due dates
Advance tax is paid in 4 instalments: 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15. For businesses under 44AD presumptive taxation, the entire advance tax is due by March 15 (single instalment). Non-payment attracts 1% monthly interest under Sections 234B and 234C.
Advance tax for freelancers and consultants
Freelancers and consultants often underestimate their tax because TDS is deducted at only 10% on professional fees, while their actual slab may be 20–30%. The shortfall must be covered through advance tax. Missing all advance tax payments and paying the full amount at year-end results in interest of typically 1–3% of the total tax — a significant but avoidable cost.
