What is a tax calculator?

A tax calculator is a tool that helps you to estimate and understand the amount of tax you owe. In the context of UK Income Tax, we are specifically referring to an online Self Assessment tax calculator. In essence, this is a (typically free) software which provides a breakdown of your specific tax obligations towards HMRC.

What are the benefits of a tax calculator?

Working out whether you need to pay tax (and how much) is confusing at the best of times. When filing your tax returns, the range of financial factors involved can often feel overwhelming. Luckily, Self Assessment software is available to help make sense of the numbers and identify any errors.

Online tax calculators automatically generate a detailed breakdown of your Income Tax obligations, according to your individual circumstances. This breakdown shows you the range of variables added and subtracted from your total tax due. This can be invaluable when preparing your Self Assessment for HMRC.

Using Self Assessment software in this way increases tax transparency. By providing you with a clear breakdown of your individual tax variables, it empowers you take control and understand the steps underlying tax. The best part is that you can do all of this for free.
