Moving from Canada to Wisconsin: Graduated Rates to 7.65%, Milwaukee's New Sales Tax, and the Twin Cities Commute

Wisconsin draws Canadians to Madison's healthcare technology and university sector, Milwaukee's manufacturing and financial services employers, and the western counties along the St. Croix where Twin Cities workers live for the lower cost of living. Wisconsin's tax picture is a graduated income tax topping out at 7.65%, moderate sales tax that Milwaukee County raised in 2024, high property tax, and no estate tax. The commuter question matters: Wisconsin and Minnesota ended their reciprocity agreement in 2010, so a Hudson resident working in St. Paul files in both states.

Key takeaways

• Wisconsin's graduated income tax runs 3.5% to 7.65%. No local income taxes.
• Wisconsin and Minnesota have had no reciprocity agreement since 2010; a Wisconsin resident working in Minnesota files a Minnesota non-resident return and claims a Wisconsin credit.
• Sales tax is 5% state plus local, 7.9% in Milwaukee County since 2024, 5.5% in Dane County.
• Property tax is high, near 1.6% effective.
• No estate tax. Wisconsin starts from federal AGI and exempts Social Security.

The Canadian departure

Departure tax applies to non-registered investments, private company shares, crypto, and foreign property at fair market value on the day you leave. Canadian real estate, RRSPs, TFSAs, and pensions are excluded. Report on Form T1243, list holdings on Form T1161 if the total exceeds $25,000, and post security under Form T1244 to defer tax on illiquid assets. The rate is your province's: on a $300,000 unrealized gain, roughly $72,000 from Alberta and $80,000 from Ontario, Quebec, or BC. Provincial health coverage ends around your departure date; confirm the exact date with your plan and arrange US coverage to start the same month.

US federal side

Dual-status return in the arrival year, FBAR on Canadian accounts above $10,000 aggregate, Form 8938 above thresholds, and the RRSP treaty deferral federally. The TFSA loses its tax-free status the day you become a US person; close it before crossing. Equity compensation vesting after the move is split by working days between Canada and the US.

Wisconsin's side

Graduated income tax from 3.5% to 7.65%; no local income taxes; 5% state sales tax plus local, 7.9% in the City of Milwaukee after the 2024 city and county increases and 5.5% in Dane County (Madison); property tax near 1.6% effective with a lottery and gaming credit and a school levy credit; no estate tax. Wisconsin starts from federal AGI, exempts Social Security, and excludes 30% of long-term capital gains. A Wisconsin resident working in Minnesota pays Minnesota non-resident tax and claims a Wisconsin credit; the net effect approximates the higher of the two rates.

The RRSP

Federally deferred under Article XVIII of the treaty and deferred for Wisconsin because the state starts from federal AGI. Withdrawals face 25% Canadian withholding on lump sums, 15% on periodic RRIF payments within the treaty limit, a US foreign tax credit federally, and Wisconsin's graduated rates. CPP and OAS, treated like Social Security under the treaty, are exempt from Wisconsin tax.

Who makes this move

Canadian healthcare technology professionals to Epic Systems in Verona and Madison's health-tech sector, Canadian academics to the University of Wisconsin, Canadian manufacturing and finance staff to Milwaukee's employers (Rockwell Automation, Northwestern Mutual, Harley-Davidson), and Manitoba and Ontario professionals working in the Twin Cities who choose Hudson or River Falls.

Worked example

A Toronto health-tech engineer moves to Madison on June 30 with $200,000 of unrealized gain in a non-registered account, $450,000 in an RRSP, and a Toronto condo sold in the departure year.

• Departure tax. $200,000 gain, $100,000 taxable, at about 53.5%: roughly $53,500.
• Condo. Sold as a resident under the principal residence exemption.
• RRSP. No tax on departure; federal and Wisconsin deferral.
• Madison. Combined top rate about 44.65%. HST 13% becomes sales tax 5.5%. Property tax on a $500,000 home around $8,000.

"When you leave Canada, you are considered to have sold certain types of property (even if you have not sold them) at their fair market value (FMV) and to have immediately reacquired them for the same amount. This is called a deemed disposition and you may have to report a capital gain (also known as departure tax)." — Canada Revenue Agency, Leaving Canada (emigrants), https://www.canada.ca/en/revenue-agency/services/tax/international-non-residents/individuals-leaving-entering-canada-non-residents/leaving-canada-emigrants.html

"You will be considered a United States resident for tax purposes if you meet the substantial presence test for the calendar year. To meet this test, you must be physically present in the United States (U.S.) on at least: 31 days during the current year, and 183 days during the 3-year period that includes the current year and the 2 years immediately before that." — Internal Revenue Service, Substantial Presence Test, https://www.irs.gov/individuals/international-taxpayers/substantial-presence-test

Practitioner note

The Wisconsin-Minnesota commuter question is the one most often answered wrong: the reciprocity agreement ended in 2010 and has not been restored, so a Hudson resident working in St. Paul files both returns. For most, the result is close to Minnesota's rate anyway, and the Wisconsin advantage is property price rather than income tax.
