Estate Planning Laws in Wisconsin.

Wisconsin's marital-property (community-property) regime, effective January 1, 1986. Property acquired during marriage is generally marital property, producing a full federal step-up in basis for both halves at the first spouse's death.

Wisconsin's probate framework — covering wills, intestacy, probate administration, and informal probate procedures.

Wisconsin's enactment of the Uniform Trust Code (effective 2014) — the principal framework for trust creation, modification, and administration.

Wisconsin's estate tax (the federal "pickup" tax) ceased to operate when federal law eliminated the state-credit mechanism; Wisconsin has no state estate or inheritance tax as of 2026.
