The HMRC App allows you to:
• Calculate your income tax
• Find a form
• Go to HMRC guidance and tools on GOV.UK
HMRC Tax Calculator
Estimate how much Income Tax and National Insurance contributions you can expect to pay if you are a UK taxpayer paying tax through PAYE and pay Class 1 NI contributions.
This simple calculator only works with National Insurance letter A. If your tax affairs are complex it won’t give an accurate estimate. It doesn’t calculate any other taxes.
You will not be asked to provide any personal information. The information you enter isn’t stored by HMRC or used for any other purposes. The calculation result is not legally binding nor is it a demand for payment.
Search for HMRC forms, supplementary pages, worksheets and related help and guidance.
HMRC guidance and tools on GOV.UK
Guidance, tools and calculators from the UK's tax authority including help and support if you're self-employed or employ people.
Note that this app is for UK users only.
What's New in Version 4.2
Added a Support Information page showing the app version and other details we might ask for if you need support from us. You’ll find it under the settings menu.
An odd choice for a mobile app when online calculators are available, but if you want to calculate your taxes on your iOS device, you are now able to do so.
