"There's a reason for the high review scores posted for this app...it is an extremely well designed and thought out app."

"Brilliant app. Just saved me £160. Email and print give a very clear printed breakdown."

"This app is easy to use...I rarely write app reviews, but this one deserves all the praise it gets..."

"Outstanding - one of the best personal finance apps available."


Tax Tool 2013 (formerly UK Tax Tool) was inspired by the quality of Apple's own apps. It was designed to be comprehensive, but also to be very easy to use and input information.

Choose to enter as much or as little as you want: accuracy is improved if you enter more information and if you enter your Tax Code, but it still gives a useful rough guide if you enter none of these.

A key feature is that it can perform reverse salary calculations. You can enter your desired take-home pay (what you need to receive, after payroll taxes are deducted, to cover your everyday lifestyle) and Tax Tool 2013 will instantly work out the salary needed to achieve that target. You can easily flip between these to work out net pay from gross salary or vice-versa.

The app also performs UK VAT calculations, and contains a handy reference for UK tax rates, limits and allowances.

Tax Tool 2013 is designed for UK taxpayers in paid employment, using the Pay-As-You-Earn (PAYE) system of automatic tax deduction. It’s a ‘ready reckoner’ in your pocket.

Quick and simple: this is not designed to be a replacement for a full tax return (it doesn’t ask for full details on all your financial affairs), but it does provide a quick and useful estimate of the amount you will receive in your pay packet.

The app is in active development. Please contact us with any issues, feedback or suggestions – our email address is uktaxtool@gmail.com.
