HMRC Calculator Services

HMRC has a range of checkers and calculators to ensure you’re paying the right amount of tax or getting all the benefits that you are entitled to. Below is a list of the calculators and other services, as well as how they work.

HMRC Income Tax Calculator

HMRC has two calculators for income tax- one to check if you have overpaid tax, and the other to predict how much tax you will be paying this year.

You must enter your income for the year before tax, as well as how much tax you paid. The calculator will then tell you if you have overpaid. It won’t tell you if you have underpaid however, only that you are not due a refund.

You can use the checker to work out if you may be due a tax refund if all of the following apply:
You were born after 5 April 1938
You are a basic rate (20%) or higher rate (40%) taxpayer
You get the basic Personal Allowance of £10,600 (2015 to 2016 tax year.

Benefits Calculators

HMRC does not have it’s own benefits calculator, but you can use an independent one such as Turn2Us or Entitledto to see if you are eligible for any welfare benefits that you are not already receiving.

You can’t use the calculators if you are under 18 and they won’t give accurate information if you are a prisoner or student.
