When this applies
- Your estimated liability is above the threshold and you need the four instalments.
- You want to check you have paid the right cumulative amount by a due date.
- You are setting aside money through the year for the March payment.
- You are estimating interest exposure before deciding how much to pay now.

What this calculator does
Split an estimated annual tax liability into the four advance-tax instalments, showing the cumulative percentage due by each date and the amount payable in each instalment.
How this is calculated
Advance tax is paid in four instalments through the year, and each one is a cumulative percentage of the year's estimated tax: 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March. The amount due in each instalment is that cumulative figure minus what has already been paid, which is what this calculator shows alongside the cumulative totals. The percentages above apply to taxpayers who are not computing income on a presumptive basis.
The formula
Cumulative: 15% · 45% · 75% · 100% by the four due datesCommon mistakes to avoid
Paying one quarter of the tax each time
The instalments are not equal. The first is only 15% and the last is 25%, so dividing by four leaves you short early and overpaid later.
Forgetting the cumulative basis
Each date is tested against the cumulative percentage of the year's tax, not the quarter's income. Testing each quarter on its own misses the rule.
Ignoring the 15 March instalment
The final instalment is the largest step for many taxpayers, and missing it attracts interest under 234C.
Not re-estimating mid-year
The estimate is meant to be revised at each date. Paying against a stale estimate leaves a shortfall that interest is charged on.
Frequently asked
- What are the advance tax due dates?
- 15 June, 15 September, 15 December and 15 March, with cumulative percentages of 15%, 45%, 75% and 100% of the estimated annual tax for non-presumptive taxpayers.
- Do I have to pay if my liability is small?
- Advance tax is generally required once the estimated liability for the year is above the threshold. Below it, it is not payable. Confirm the current threshold, which can change.
- How is each instalment amount worked out?
- Take the cumulative percentage for that date, apply it to the year's estimated tax, and subtract what you have already paid. That difference is the amount due now.
- What if my income estimate changes during the year?
- Re-estimate at each instalment date and adjust the remaining payments. Paying at least the cumulative percentage of your revised estimate by each date avoids interest under sections 234B and 234C.
- What happens if I underpay?
- Interest is charged on the shortfall - 234B for not paying enough overall and 234C for deferring an instalment. Paying the right cumulative amount by each date is what avoids it.
