Answer:
The U.S. tax code allows an unlimited marital deduction to transfer the entire estate to the survivor tax-free, assuming the recipient is a U.S. citizen.
Step-by-step explanation:
The United States Federal Estate and Gift Tax Law provide the unlimited marital deduction for a person who wishes to transfer an unlimited number of assets to his/her marriage partner even if the original owner has passed away, without having to pay any tax. Such institutions consider this deduction an estate preservation tool since surviving partners can perceive these assets free from tax obligations.
