"Whichever side has the better price." That's how most buyers explain the choice between Hudson and Stillwater, as if the St. Croix River were the only line that mattered. It isn't. A state line runs down the middle of that water, and unlike the bridge, it doesn't get shorter just because the drive does.
Buyers comparing these two towns tend to treat them as interchangeable versions of the same river lifestyle, just with different zip codes. The commute is similar. The scenery is the same water. But Wisconsin and Minnesota tax income, property, and cross-border work in genuinely different ways, and one of those differences has been sitting there since 2010, mostly unnoticed by anyone who hasn't had to file taxes on both sides of it.
The Bridge Doesn't Erase the Border
Wisconsin and Minnesota used to have an income tax reciprocity agreement. For more than 40 years, it let someone who lived in one state and worked in the other file a single state income tax return, in their home state, instead of two. Minnesota ended that agreement effective January 1, 2010, citing disputes over late reimbursement payments from Wisconsin. It has not come back.
Wisconsin lawmakers have tried to revive it. A 2023 law, Wisconsin Act 147, directed the state's Department of Revenue to study what reinstating reciprocity with Minnesota would actually cost each state, using 2020 and 2021 tax year data. That study was delivered in December 2024. As of this writing, no new agreement is in place. Any future deal would still need sign-off from both states' revenue departments, Wisconsin's governor, and the legislature's Joint Committee on Finance, so this isn't a formality waiting on paperwork. It's a negotiation that has been stalled for over fifteen years.
What that means in practice: a Wisconsin resident working in Minnesota has Minnesota income tax withheld from every paycheck and files a Minnesota nonresident return. They also file a Wisconsin resident return and claim a credit for the tax already paid to Minnesota. A Minnesota resident working in Wisconsin goes through the mirror version. Neither ends up taxed twice on the same dollar, but both end up filing twice, tracking two withholding forms (Wisconsin's WT-4 alongside Minnesota's W-4MN), and reconciling two returns every April instead of one.
Wisconsin's Department of Revenue has even built a special exception for employers who have operations in both states, allowing them to skip double withholding for Wisconsin residents working in Minnesota under certain conditions, specifically because the standard process was creating enough hardship for cross-border workers that the state felt it needed a workaround. That's not a footnote. That's a state agency admitting the current system creates friction for exactly the kind of commuter Hudson and Stillwater both attract.
Five minutes across the bridge changes your commute. It does not change how many state returns you file each April.
The Number That Actually Shows Up at Closing
Set the tax filing question aside for a moment and look at what the two markets are actually doing with price.
| Hudson, WI | Stillwater, MN | |
|---|---|---|
| Median sale price, citywide | Roughly $420,000 (three months ending June 2026) | Roughly $432,000 (as of June 2026) |
| Typical days on market | About 29 days (three months ending June 2026) | Roughly 22 to 27 days (active listing data pulled July and August 2026) |
| Effective property tax rate | About 1.26% | Roughly 1.0% to 1.4% across the Twin Cities metro |
The headline median prices sit close enough to call it a wash, and both towns are moving fast, with Stillwater's active listings generally turning over a few days quicker than Hudson's. That alone doesn't settle the comparison. The last clear per-square-foot read available for both markets, from data covering the back half of 2025 into early 2026, put Hudson around $211 per square foot against Stillwater closer to $238, a gap of roughly 13 percent. That comparison predates part of this year's price movement on both sides of the river, but given Stillwater's median has continued to run above Hudson's through June 2026, the underlying premium has more likely held than closed. Median sale price is also easy to skew with a handful of unusual closings in either direction. A market this size doesn't need many big estate sales or many small starter homes to swing its median a lot in one month, which is exactly why the per-square-foot comparison matters even when it isn't perfectly current.
Stillwater's own downtown segment makes that point clearly. Public sales data for the Downtown Stillwater submarket specifically showed a median sale price around $532,500 in January 2026, down close to 17 percent year over year, in a pocket where Victorian-era homes on half-acre in-town lots share the market with condo conversions from the 1880s. That's not a shrinking market. That's a small number of very different homes trading in the same twelve-month window and dragging the median around with them. Anyone using the citywide Stillwater median to estimate what a specific listing near downtown should cost is comparing apples to a fruit basket.
Hudson doesn't have a directly comparable downtown breakout in the same data set, but the same logic applies. The city's inventory mixes historic homes near the river with newer construction in the subdivisions further from the water, and a buyer targeting one segment specifically should ask their agent for that segment's numbers, not the citywide blend.
Where Minnesota Wins and Where Wisconsin Wins
Property tax and income tax pull in opposite directions here, and neither state comes out ahead once you add both together for a typical household.
Minnesota's property tax rates in the Twin Cities metro generally run lower than Wisconsin's, landing in that 1.0 to 1.4 percent range depending on the city and school district. Hudson's effective rate, calculated from actual tax bills against assessed value, sits closer to 1.26 percent, with a median annual bill in the mid-$4,000s. On property tax alone, Minnesota has the edge for a comparably priced home.
Wisconsin's advantage shows up on the income tax side, particularly for higher earners, and Wisconsin has no state estate tax. For a household with a strong income and a moderately priced home, Wisconsin's income tax structure can offset what they'd lose on property tax. For a household with a more modest income and an expensive home, Minnesota's lower property tax rate can win out instead.
There's no universal answer here, and that's the point. The right side of the river depends on your specific income level and home price, not on a general reputation either state has for being "cheaper." A household earning $180,000 a year and buying at $450,000 will run this math very differently than a retired couple with modest income buying the same house.
The Commute Routes Are Doing Different Jobs
Part of why Stillwater commands a higher price per square foot traces back to which commute it's actually selling. Stillwater sits about 20 miles from St. Paul and 26 miles from Minneapolis, with Highway 36 as the primary route into St. Paul, roughly 25 to 30 minutes under normal conditions, and into Minneapolis via the I-35W interchange, closer to 35 to 40 minutes, more with any backup at that interchange during rush hour.
Hudson's draw runs through the I-94 corridor instead, which is the more direct route for buyers whose jobs sit further out in the eastern Twin Cities suburbs or who are commuting into Minnesota via that highway rather than through St. Paul surface streets. Buyers choosing between the two towns aren't just picking a house. They're picking which highway interchange they're willing to sit at during a bad Tuesday morning, and that choice has been part of what shapes the price gap all along.
Before You Compare List Prices, Run These Numbers
- Ask what your specific employer situation means for withholding. If you'll be crossing state lines for work, confirm with your employer's payroll department whether they'll handle Wisconsin's WT-4 or Minnesota's W-4MN correctly, since getting this wrong is what turns a routine cross-border move into a surprise tax bill in April.
- Compare price per square foot, not just median sale price, especially in a market where a handful of sales in either direction can move the median significantly in one direction.
- Pull the actual assessed value and current tax bill on any specific home you're considering rather than relying on a citywide average rate, since Hudson's own tax notices show meaningful variation even within the same zip code.
- Time-test your actual commute route, not the mapped estimate, particularly if Highway 36 or the I-35W interchange is part of your daily drive.
FAQ
Will I be double-taxed if I live in Hudson and work in Stillwater, or the reverse? No. You'll file a nonresident return in the state where you work and a resident return in the state where you live, claiming a credit for tax already paid to the work state. What you lose isn't money on the same dollar, it's the convenience of filing once instead of twice, which the two states used to allow before Minnesota ended the reciprocity agreement in 2010.
Is Hudson actually cheaper than Stillwater? It depends which number you weight. Hudson's price per square foot runs lower, and its property tax rate sits above Minnesota's typical metro range, while Wisconsin's income tax advantage tends to matter more the higher your income climbs. There's no single answer that applies to every household, which is exactly why running your own numbers matters more than trusting either state's reputation.
