Why Advance Tax Planning Matters
Advance tax under Sections 207-211 of the Income Tax Act applies to every assessee whose tax liability for the financial year exceeds ₹10,000 after TDS credit. The interest exposure under Section 234B (1% per month for non-payment) and Section 234C (1% per month for shortfall in installments) makes accurate quarterly tax projection a high-impact compliance activity. For salaried individuals with significant capital-gains income, freelancers, professionals under presumptive taxation electing out, and corporate entities, the difference between disciplined advance tax payment and ad-hoc payment can be 6-12% of the year's tax liability.
The Quarterly Installment Schedule
For all assessees other than those electing presumptive taxation under Section 44AD/44ADA: 15% by 15 June, 45% cumulative by 15 September, 75% cumulative by 15 December, and 100% by 15 March. For 44AD/44ADA presumptive assessees, a single 100% installment by 15 March is sufficient. Capital gains and casual income are exempt from the first installment but must be included in subsequent installments based on when they are realised — a common error among individuals with mid-year property sales or LTCG events.
Our Advance Tax Process
Each quarter, we project income from all heads (salary, business/profession, capital gains, house property, other sources), apply appropriate slabs and surcharge for the assessee's regime (old vs new), deduct expected TDS based on Form 26AS / AIS, and compute the advance tax payable. We also run scenario analyses for major expected events (property sale, ESOP exercise, dividend distributions) to ensure the right installment captures the liability. The deliverable is a one-page advance tax memo with the challan amount, due date, and reconciliation against year-end estimate.
Sections 234B and 234C — Avoidance Strategy
Section 234C interest is assessed installment-by-installment — even if the year-end advance tax is fully paid, an installment shortfall at any quarter triggers interest. Section 234B applies if 90%+ of the assessed tax is not paid as advance tax. The combined interest cost can run 6-9% of the assessed tax for delayed payments. We design the quarterly review cadence to avoid both — including the 15 March residual sweep that catches any year-end income not previously projected.
Special Situations — Capital Gains, ESOPs, Dividends
Section 234C provides relief for unexpected capital gains and dividend income — an installment shortfall arising from these sources, where tax is paid in the next installment in which the income arose, does not attract interest. Documentation of the timing of the realisation event is essential to claim this relief. We maintain such documentation as a standard part of our advance tax engagement deliverables.
Engagement
Quarterly advance tax engagements are billed on a fixed-fee basis covering all four installments plus the year-end ITR filing. For complex cases (non-residents, multi-source income, ESOP-heavy compensation, or significant capital-gains activity), we offer a more intensive monthly tax-projection model.

Frequently Asked Questions
Who is required to pay advance tax?
This service can be provided by qualified professionals with relevant credentials. At Virtual Auditor, CA V. Viswanathan holds FCA (ICAI), ACS (ICSI), CFE (ACFE USA), and IBBI Registered Valuer (IBBI/RV/03/2019/12333) certifications — covering the full spectrum of regulatory requirements. Our practice operates from Chennai, Bangalore, and Mumbai.
What are the advance tax due dates?
The specific requirements, documents, and procedures are detailed in the relevant regulatory provisions. Virtual Auditor provides comprehensive support including documentation, filing, representation, and follow-up. Our multi-credential team ensures nothing is missed across regulatory intersections.
What is the interest rate under Section 234B and 234C?
Both charge simple interest at 1% per month or part of a month. Section 234B of the Income-tax Act, 1961 (section 424 of the Income-tax Act, 2025 from tax year 2026-27) applies when advance tax paid is less than 90% of the assessed tax, from 1 April following the year until the tax is paid. Section 234C (section 425 of the 2025 Act) applies to shortfalls in the individual instalments (15 June, 15 September, 15 December, 15 March), charged for three months per instalment (one month for the March instalment).
Is advance tax required for capital gains?
The answer depends on the specific provisions of the applicable Act/regulation and your factual situation. Virtual Auditor provides definitive advisory backed by FCA + ACS + CFE + IBBI RV credentials. Contact us for clarity.
How is advance tax calculated for business income?
Estimate the year's total income from all sources, compute tax at the applicable rates (plus surcharge and cess), deduct TDS/TCS credit and relief, and pay the balance in instalments: 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March. Taxpayers under the presumptive schemes (sections 44AD/44ADA of the Income-tax Act, 1961; section 58 of the Income-tax Act, 2025 from tax year 2026-27) may pay the whole amount by 15 March. Advance tax is payable when the liability after TDS exceeds ₹10,000.
What are the tax consequences of my proposed transaction or income situation?
We need four facts: who you are (resident or not, and your entity type), the tax year, what is being sold or received, and when it was acquired and for how much. From these we work out the head of income, the holding period and whether the gain is short or long term, the rate (for example 12.5% without indexation on most long-term gains from 23 July 2024), any exemption by reinvestment in a house or specified bonds, tax deducted at source, and any treaty relief if you are a non-resident (the Income-tax Act, 1961 for tax years up to 2025-26; the corresponding provisions of the Income-tax Act, 2025 from tax year 2026-27). You receive a written note comparing the lawful options, with the assumptions, the records to keep and the filing steps.
