Advance Tax Calculator

What does this tool calculate?

This tool estimates your tax for FY 2025-26 under either the new or the old regime, subtracts the TDS you expect, and if the remainder is ₹10,000 or more splits it into four cumulative instalments. The labelled dates are June 15, September 15, December 15 and March 15, at 15%, 45%, 75% and 100% cumulative. The instalment amounts are therefore 15%, 30%, 30% and 25% of the net figure.

How is annual tax worked out inside the tool?

It subtracts a standard deduction (₹75,000 in the new regime, ₹50,000 in the old) from the income you enter, plus your deductions field for the old regime only, and applies slabs from 0% to 30% before adding 4% cess. The new-regime slabs have seven rows and the old-regime four. If taxable income is within the coded rebate limit, tax is zero. Tax rules change every year, this tool’s tables are not updated automatically, and the Income Tax Department or a qualified adviser governs.

When does the tool say advance tax is not applicable?

When tax after cess minus the TDS you entered is below ₹10,000. In that case it shows Not applicable, the net liability and a short note instead of instalments. The test is on the net figure, so a high TDS entry can move you below the line, and an income that produces zero tax always lands there.

Does it calculate interest or penalties on late payment?

No. Although the tool mentions due dates, it does not compute interest on shortfalls or late instalments, and it does not know what you actually paid or when. It only splits the net figure. If you have paid some instalments already, you will need to work out the remaining balance yourself.

Is the standard deduction applied to every taxpayer?

Yes. The tool always subtracts the standard deduction for the regime you pick, whatever type of income you have, because it has no employment-type input. If a large part of your income is from business or other sources where that does not apply, the taxable income and tax it shows will be lower than the true figure.

Are presumptive-scheme and senior-citizen rules covered?

No. The tool uses one schedule of four instalments for everyone and does not model a single March instalment, age-based exemptions or different slabs. It also treats all income as one amount at normal slab rates, so capital gains and other special-rate income are not separated.

What happens at zero income?

A zero income, which is also what an emptied box becomes, returns Advance tax ₹0 straight away. A positive income whose tax after TDS is below ₹10,000 shows Not applicable. Deductions larger than income simply bring taxable income to zero.
