Why Wisconsin has no estate tax
The Legislative Fiscal Bureau’s informational paper on the estate tax explains the mechanism: “the state estate tax was modified under 2001 Act 16”. For a specified period Act 16 linked the Wisconsin tax to the federal credit as computed before the 2001 federal changes. The Department says that for a death before 2008 you consult the Form W706 instructions.
Does Wisconsin have an inheritance tax?
The Department says “There is no Wisconsin inheritance tax” for decedents dying on or after January 1, 1992, and no Wisconsin gift tax for gifts made on or after that date.
CMG’s inheritance tax by state page covers the beneficiary side.
What applies to a Wisconsin estate instead
Federal estate tax is separate. Revenue Procedure 2025-32 says the One Big Beautiful Bill Act, section 70106, increased the “basic exclusion amount to $15,000,000 for calendar year 2026”.
An estate of $3,000,000 in Wisconsin owes $0 of state estate tax, and $3,000,000 is below the federal $15,000,000.
Probate: Wisconsin probate cost. Retirement accounts: how Wisconsin taxes 401(k) and IRA withdrawals.
Common mistakes
- Using Wisconsin’s pre-2008 estate tax rules for a recent death; the Department says there is no estate tax for decedents dying after December 31, 2007.
- Assuming the state answer settles the federal one, or the answer for property held in another state.
