Portability of the deceased spousal unused exclusion amount provided, and technical changes made and obsolete provisions removed.

HF 1448 allows surviving spouses to use their deceased spouse's unused federal estate tax exemption when calculating Minnesota estate taxes. The bill requires personal representatives of a decedent's estate to elect this "portability" option on Minnesota estate tax returns (or file a return if not otherwise required), making the election irrevocable. It directly affects married couples where one spouse dies before using their full federal estate tax exemption, potentially reducing estate taxes for the surviving spouse. The key change is streamlining access to this federal exemption for Minnesota estates of decedents dying after December 31, 2024.
