Does Wisconsin Have an Estate Tax?
YesWis. Stat. § 72.36 (Sunset; 2013 Wis. Act 20) — the ch. 72 estate tax "does not apply to deaths occurring after December 31, 2012, unless the federal estate tax law is modified to provide a federal estate tax credit for state death taxes." Ch. 72 remains on the books as a dormant federal-credit (pickup) tax that computes to $0, not a repealed one. Wisconsin has no inheritance tax and no state gift tax.Verified Jul 14, 2026View source. This means Wisconsin estates avoid the additional tax burden that exists in states like Minnesota, Illinois, and other jurisdictions with state-level death taxes.
What Happened to Wisconsin’s Estate Tax?
Wisconsin eliminated its state estate tax in 2005 as part of broader tax reform legislation. Before 2005, Wisconsin imposed both an estate tax and an inheritance tax, creating significant tax burdens for many families. The state legislature recognized that these taxes drove wealthy residents to other states and created administrative complexity without generating substantial revenue.
The elimination occurred during a period when many states were reconsidering their death tax policies. Wisconsin joined states like Florida, Texas, and Nevada in creating a more favorable environment for estate planning and wealth transfer.
How Does This Benefit Wisconsin Families?
Without state estate tax, Wisconsin families keep more of their inheritance. Consider the Johnson family from Milwaukee, whose patriarch left a $2 million estate in 2026. In neighboring Minnesota, this estate would face state estate tax on amounts exceeding $1.3 million. The Johnson family pays zero state estate tax in Wisconsin.
Another example involves the Peterson farm family near Madison. Their agricultural operation, valued at $4 million, passes to the next generation without state estate tax complications. This preservation of family wealth supports multi-generational farming operations throughout Wisconsin.
What About Federal Estate Tax in Wisconsin?
Wisconsin estates still face federal estate tax if they exceed the current exemption of $15,000,000. However, this threshold affects fewer than 1% of Wisconsin estates annually. Most families focus on income tax planning and probate avoidance rather than estate tax concerns.
How Does Wisconsin Compare to Neighboring States?
Wisconsin’s lack of estate tax (or inheritance tax) provides a competitive advantage over several neighboring states. Illinois imposes estate tax on estates exceeding $4 million, while Minnesota taxes estates above $1.3 million. Iowa eliminated its inheritance tax in 2025, joining Wisconsin in the tax-friendly category.
