Your tax bill, payment dates and monthly savings plan
Secure checkout. Your download link is sent as soon as payment clears.

If you're self-employed, nobody takes tax off your income as you earn it – you pay it yourself through Self Assessment, usually in large lump sums on 31 January and 31 July. The rules on payments on account mean the January payment can be far bigger than people expect. This planner estimates your income tax, National Insurance, student loan and High Income Child Benefit Charge for the year, sets out every Self Assessment payment with its due date, and turns it all into one simple figure: how much to put aside each month so the money is there when HMRC wants it.
