How the tools work
Each tool asks a short series of questions, applies current UK tax rules and shows you a first result straight away. To see the full breakdown on screen, which you can print or save as a PDF, we ask for your email address. Each tool page explains how it works, the assumptions it makes and what the result does and does not mean.
What the tools are for, and what they are not
They are for orientation. They help you see the scale of a question, decide whether it is worth acting on and prepare for a conversation. They are not tax advice, and they cannot replace an adviser who knows all your facts. Rules change and personal circumstances matter. Treat the numbers as an informed estimate.
Take it further
When you have a result, the next step is simple: book a free first call and bring it with you. We will go through it, test the assumptions against your actual circumstances and explain your options. You can also read about the related services in Private Families, Business Owners and International Tax.

Q1What tools does ASWATAX offer?
Three: an Inheritance Tax Calculator to estimate the likely bill on an estate, a UK Residency Checker that works through the Statutory Residence Test, and a Business Exit Calculator that compares what you keep from a sale, management buy-out or employee ownership trust. All are free.
Q2Are the tools free to use?
Yes. You can use each tool without charge and without obligation. You will see a first result straight away. To see the full breakdown on screen, we ask for your email address. You can then print it or save it as a PDF.
Q3Why do you ask for my email address?
So we can follow up if you would like to talk it through. Your full breakdown appears on screen straight away, and you can print it or save it as a PDF to keep. We use your email under our privacy policy, and you can unsubscribe from any follow-up emails at any time.
Q4Can I rely on a tool instead of advice?
No. The tools give a general first view based on the information you enter and stated assumptions. They are not tax advice and cannot take account of every detail of your situation. For a decision that matters, speak to an adviser.
Q5How current are the tools?
They are built on the rules for the 2026/27 tax year, as reviewed at 9 October 2026, and we update them when the law changes. Each tool page states the assumptions it uses so you can see what has been applied.
