Tax Calculators & Tools

Need a quick and accurate estimate of your tax position? You’re in the right place. Our collection of UK tax calculators helps you work out everything from your income tax, rental income tax and national insurance contributions to what you could claim back in your yearly mileage relief claims. Whether you're employed, self-employed or working through the CIS scheme, these tax calculators will give you a clearer view of your finances in seconds.

What are UK tax calculators for?

Tax calculators are a great way of keeping track of your tax situation. The UK tax laws are complicated, and it’s easy to end up missing out paying too much or claiming back too little. Worse still, if you’re not paying all the tax you owe on things like rental income, you could easily find yourself in hot water with HMRC.

With RIFT’s suite of UK tax calculators, you’ll see at a glance how much tax you’re likely to owe – and what kind of refund you’re owed back.
