Advance Tax Calculator

Estimate your advance tax after TDS and get the quarterly payment schedule with due dates and amounts.

How Advance Tax Calculator works

Advance tax is the pay-as-you-earn rule that requires you to pay your income tax in instalments through the year rather than all at once at the end, once your liability crosses a threshold. Missing or underpaying those instalments quietly builds interest charges, and working out how much to pay each quarter after accounting for tax already deducted is fiddly. This calculator estimates your advance tax after TDS and lays out the quarterly schedule with the due dates and the amount due at each one.

You enter your estimated income and deductions for the year, and the TDS already deducted on your behalf, and the tool computes your total tax and subtracts what has been paid through TDS. It then splits the remaining amount across the year's instalments in the prescribed proportions and shows each due date with its cumulative and instalment amounts. Because it nets off TDS first, you are not asked to pay twice on income where tax was already withheld.

The method computes your full-year liability from the slabs, deducts the TDS credit, and then applies the standard instalment percentages that build up across the four due dates so that the required share is paid by each. Salaried people often have most of their tax handled by employer TDS, while freelancers and those with capital gains or rental income are the ones who usually owe advance tax directly. Because the due dates, instalment percentages, and slab rates are set by the government, confirm the current official schedule for your year rather than assuming it never changes.

Use this when you have income that is not fully covered by TDS, which is the trigger for advance tax in the first place. If your goal is only to know which regime is cheaper or your total bill, an income tax calculator handles that, while this tool exists specifically to schedule the payments across the year.

It fits several situations. A freelancer or consultant can plan each quarter's payment so no interest accrues. An investor who booked a large capital gain can work out the extra advance tax that gain triggers. A salaried person with big side income can top up beyond employer TDS on time.

Everything is calculated in your browser, so your income and TDS figures are never uploaded or stored on a server. There is no account and no fee, and the only real limit is your device's own memory, which a tax schedule will not strain. Since interest rules and dates carry specifics this tool simplifies, confirm the exact due dates and current thresholds on the official portal before you pay.

Frequently asked questions

Who actually needs to pay advance tax?

Broadly, anyone whose total tax liability for the year after TDS crosses the official threshold is expected to pay in instalments, which most often affects freelancers, business owners, and people with large investment or rental income. Salaried people whose employer deducts enough TDS may owe little or nothing extra.

How does the calculator use my TDS figure?

It subtracts the TDS already deducted from your total computed liability, so you only schedule the balance rather than paying tax twice on withheld income. Entering an accurate TDS figure is important, since overstating it would understate what you still owe.

What are the quarterly due dates?

Advance tax follows a fixed set of instalment dates through the financial year, each requiring a cumulative percentage of your liability to have been paid. The tool lists them, but confirm the exact dates for your year on the official portal since they are government-set.

What happens if I underpay an instalment?

Underpaying or paying late generally attracts interest under the relevant sections until the shortfall is cleared. Paying each instalment on time and in the right proportion, which the schedule here helps with, is how you avoid those charges.

Does it handle capital gains that arise mid-year?

Capital gains often drive an advance tax obligation, and you can fold the resulting tax into your estimated liability, though gains realised late in the year have special timing rules. Treat the schedule as a guide and adjust as new gains arise.

Is the estimate final?

No, it is based on your projected full-year income, which can change, so revisit it if your income or deductions shift during the year. Updating your estimate keeps the remaining instalments accurate.
