Advance Tax Calculator
Estimate your income tax for the financial year under the old and new tax regimes, subtract expected TDS/TCS and advance tax already paid, and see illustrative quarterly instalments for FY 2025-26 (June, September, December, and March due dates). Built for salaried earners with side income, freelancers, and small businesses planning cash flow.
Income (annual estimates)
Deductions (old regime only in this tool)
Chapter VI-A and house loan interest on self-occupied / let-out property (Section 24) reduce taxable income only under the old regime. The new regime ignores these (except standard deduction on salary and the usual 30% standard deduction on rental used here).
Taxes already paid / withheld
Instalments use cumulative targets (15%, 45%, 75%, 100%) on total estimated tax, with your combined TDS, TCS, and advance tax entered above treated as a credit from the first milestone onward. If most TDS lands late in the year, real-world shortfall interest can differ—refresh inputs as Form 26AS updates.
Presumptive tax (44AD / 44ADA)
If you opt for presumptive taxation under Sections 44AD or 44ADA, advance tax is commonly paid in one instalment by 15 March instead of four quarterly payments.

What is advance tax and who uses this calculator?
Advance taxis the prepayment of income tax during the same financial year in which income is earned. It helps you stay aligned with India's pay-as-you-earn framework, reduces the risk of interest under Sections 234B and 234C when estimates are reasonable, and smooths cash outflows compared to a single payment at filing time. This page targets freelancers, consultants, rental owners with limited employer TDS, traders, and salaried individuals with capital gains or significant other income where employer TDS may not cover the full year liability.
FY 2025-26 quarterly schedule (normal taxpayers)
| Due date | Cumulative of estimated tax |
|---|---|
| 15 June 2025 | 15% |
| 15 September 2025 | 45% |
| 15 December 2025 | 75% |
| 15 March 2026 | 100% |
Amount to pay for each slot is the cumulative target minus tax already paid (including TDS/TCS and advance tax credited). Payments on or before 31 March 2026 can still count as advance tax for the same financial year in many situations. Presumptive businesses may use a single March instalment instead.
Keywords: old vs new regime and rebates
Your advance tax estimate depends on which tax regime you choose when filing. The calculator shows old regime slabs with Chapter VI-A deductions and new regime slabs with a higher standard deduction on salary (illustrative ₹75,000) and no personal deductions in the model. Rebate and marginal relief around slab boundaries follow the same illustrative pattern as our tax regime comparator. Surcharge on very high incomes is not built in—refine with a CA if you are in the top brackets.
Interest if you fall short
- Section 234B — broadly, interest on shortfall when aggregate advance tax and TDS is below a specified percentage of final assessed tax by year-end.
- Section 234C — interest on deferred instalments when cumulative paid by each due date is below required percentages, subject to exceptions (e.g. safe-harbour percentages for early quarters in some cases).
Frequently asked questions
What is advance tax in India?
Advance tax means paying income tax in instalments during the financial year based on your estimated income, rather than only at the time of filing the return. It applies when estimated liability after TDS/TCS remains significant—commonly above ₹10,000.
Who should pay advance tax?
Individuals and businesses whose net estimated tax crosses the threshold after crediting TDS and TCS usually pay advance tax. Typical cases include independent professionals, business owners, landlords, and employees with large non-salary income. Resident senior citizens (60+) without business or professional income are often exempt.
How is advance tax different from TDS?
TDS is collected by payers on specified transactions. Advance tax is paid by you on self-assessment of total yearly tax. Both reduce final liability on the return; only the payer and timing differ.
What are the due dates for FY 2025-26?
Under the standard pattern: 15 June 2025 (15%), 15 September 2025 (45%), 15 December 2025 (75%), and 15 March 2026 (100%), each as a cumulative share of estimated total tax after credits. Section 44AD/44ADA taxpayers often pay 100% by the March due date only.
Do I include capital gains?
Yes. Include expected capital gains in your annual estimate when you can reasonably project them; you can top-up remaining instalments once a sale is completed.
Is this calculator legal or filing advice?
No. It is an educational illustration using simplified slabs and cess. Use the official income tax e-filing portal, AIS/Form 26AS, and a qualified adviser for compliance.
