Tax is usually one of the main reasons that lead our clients to make inquiries about a Will. The concern to know the amount of taxes that their heirs will have to pay if they die.
The problem is that, as we all know, taxes are something that all governments like to change frequently. Therefore it is impossible to know if what is now in force will be what is applied six months later.
What we can do, and do, is make an estimate. A calculation based on the value of the inheritance at the time the Will is made taking into account the tax rules in force at the time. It is not definitive but it helps our clients in many cases to decide on making their Will in one way or another.
