Dear Liz: You mentioned that the federal estate tax exemption limit this year is $5.49 million per person. Can I double that if married?
Answer: Essentially, yes. Married couples can double the amount that can be given or bequeathed to heirs tax free. If one spouse doesn’t use up his or her exemption, the surviving spouse can use the remaining amount in addition to the surviving spouse’s own exemption.
You also should know that you can leave an unlimited amount of money to a spouse who is a U.S. citizen. (The rules for non-citizen spouses are different and could fill a whole column on their own.) This is known as the unlimited marital deduction.
