While the devil is in the details, it is possible that if President Biden’s elimination of step-up in basis proposal is passed by Congress you could be paying an estate tax at 40%, and a capital gains tax at 43.4%.
The graphic below shows an example of a business worth $50 million, and at the founder’s death, an 81% tax COULD be paid.
So pay close attention to what is being discussed and let your members of Congress know you do not support elimination of step up in basis.
