Inheritance tax can be a complicated topic and this calculator is intended to help you understand some of the key areas. It has been prepared in good faith and is based on our understanding of the law and our interpretation of it. However we do not provide tax advice. So, although we have tried to illustrate the effect of inheritance tax in a simpler manner, this calculator is not intended as a proxy for taking professional advice.


The calculator does not take into account levels of income and expenditure and how these may impact the estate value over time.


The output of the calculator is based on current legislation, which may be subject to change. This is for illustrative purposes only and does not constitute advice.


This calculator is provided for illustrative purposes only and does not constitute advice by TIME Investments (‘TIME’) and should not be taken as a basis for investment. Independent tax advice should be obtained and TIME does not warrant that this calculator is free from error.
