Hudson's Lower Price Tag Comes With a Second Tax Return You Didn't Budget For

Every April, someone who lives in Hudson and earns a paycheck in downtown St. Paul or Minneapolis sits down to do something their neighbor across the river never has to. They file two state income tax returns instead of one: a Minnesota return reporting the wages earned there, and a Wisconsin return reporting everything else, with a credit claimed for the tax already paid to Minnesota. For more than 40 years, a reciprocity agreement let cross-border commuters skip that second return entirely. Minnesota ended the agreement effective January 1, 2010, and it has stayed ended ever since.

That filing requirement never shows up on a listing page. It matters because it sits right next to the number that does show up on every listing page: Hudson homes cost less than Woodbury homes. That gap looks like straightforward savings until you follow the tax math all the way through, and at that point it starts to look less like a discount and more like a trade.

The Gap on Paper

Over the three months ending in June 2026, Hudson homes sold for a median of $420,000, up 3.0 percent from the same period a year earlier, with homes going under contract in about 29 days on average, down from 43 days the year before. Woodbury, over the three months ending in August 2026, posted a median sale price of $499,000, up 5.1 percent year over year, with homes selling in about 28 days and drawing an average of three offers.

That's roughly a $79,000 gap, and it's tempting to read it as pure savings for crossing the river. The pace of both markets undercuts one common assumption too. Nobody should walk into Hudson expecting a slower, quieter market than Woodbury this year. Both are moving at almost identical speed, both are drawing competitive offers, and neither side of the St. Croix is sitting still waiting for buyers.

Where the Savings Start to Disappear

The price gap is real. What happens after closing is where it gets complicated. Wisconsin's average effective property tax rate runs around 1.32 percent of home value, compared to roughly 1.00 percent in Minnesota. On a $400,000 home, that difference works out to about $1,280 more per year in property tax on the Wisconsin side.

Wisconsin's income tax structure works in the opposite direction for most earners. Its top rate caps at 7.65 percent, well below Minnesota's 9.85 percent. At $100,000 in income, that translates to roughly $4,696 in Wisconsin state income tax versus about $5,277 in Minnesota, a savings of around $581 a year.

Put those two numbers next to each other and the property tax gap wins. A Wisconsin homeowner earning $100,000 saves about $581 a year on income tax but pays about $1,280 a year more in property tax on a $400,000 home, which nets out to roughly $699 more in combined state and local tax than the same household would pay living in Minnesota. The lower purchase price in Hudson is real. The lower total cost of ownership isn't guaranteed, and at this income level it actually runs the other way.

The Math Flips at Higher Incomes

None of this holds at every income level, which is exactly why it's worth running before you write an offer instead of after. At $250,000 in income, Wisconsin's income tax savings jump to roughly $4,777 a year, comfortably outweighing the property tax gap on most homes in that price range. At $500,000, the savings grow to around $12,220 a year. Above a certain income, Wisconsin genuinely comes out ahead on taxes, sticker price included.

At the lower end, the pattern gets stranger still. At $50,000 in income, Minnesota is actually about $187 cheaper on income tax alone, because Wisconsin's effective standard deduction is smaller at that bracket. Layer the property tax gap on top of that and a lower-income household crossing the river for a cheaper house can end up paying more in total state and local tax than they would have paid staying in Minnesota, even before counting the second tax return.

There's no single answer to whether Hudson or Woodbury costs less to own. The honest answer is that it depends on where your household income sits, and the crossover point is worth calculating with actual numbers rather than assumed.

Why There's No Quick Fix

Wisconsin lawmakers have pushed for years to study reviving the reciprocity agreement with Minnesota, and Minnesota's Department of Revenue currently lists reciprocity agreements only with Michigan and North Dakota, not Wisconsin. Reporting from Wisconsin Public Radio on the legislative effort describes a study process aimed at reviving the deal, not a reinstated agreement. As of now, nothing has changed for the households doing this math. If you're planning a move across the St. Croix, plan around the returns you'll be filing this year, not the ones you might file someday.

The Bridge Work Wraps Up Next Month

If you're touring homes in Hudson right now, you're catching the tail end of a construction season that has shaped commutes all year. The Wisconsin Department of Transportation has been rehabilitating the I-94 bridges over the St. Croix River between Hudson and Lakeland, with 2026 construction running from April 6 through late October. Westbound traffic has been held to two lanes for stretches of the project, with one lane shifted onto the eastbound structure. The work is unrelated to the newer St. Croix Crossing bridge that opened in 2017 a few miles north. This is routine deck and joint maintenance on the older I-94 crossing, and it closes out for the season within weeks.

What's Actually New on the Wisconsin Side

Hudson isn't standing still while the tax math gets sorted out. Creative Homes brought a new paired-home community called Canter Crossing to Hudson earlier this year, offering both quick move-in homes and build-to-order options, which gives buyers weighing the price gap an alternative to competing for existing inventory.

Longer term, St. Croix County is extending the Highway 35 Off-Road Trail, a project that will eventually link Hudson and North Hudson to schools, parks, and shopping before connecting north and west into Houlton, Stillwater, and the broader Twin Cities Regional Trail System. Once finished, the network runs 33 miles from Afton, Minnesota to the I-94 bridge crossing at Hudson. Design work on the next phase began over the winter, with construction tentatively planned for 2027 or 2028, so this is a future amenity to factor into a longer-term decision rather than something in place today.

Running the Numbers on Your Own Address

The comparison that matters isn't Hudson versus Woodbury in the abstract. It's your household income against the specific property tax bill on a specific address, on both sides of the river, run side by side before you write an offer. A $420,000 Hudson listing and a $499,000 Woodbury listing aren't apples to apples until you've added the property tax difference at that price point, checked where your income falls on the reciprocity-free tax comparison, and decided whether the second tax return every spring is worth the trade for your situation. Being licensed in both Minnesota and Wisconsin means that comparison can happen on one call instead of two.

A Few Questions Worth Asking Before You Cross the River

Does the lack of reciprocity mean I get taxed twice on the same income? Not exactly. The state where you live gives you a credit for tax paid to the state where you work, so you're not paying the full rate twice. What you are doing is filing two separate returns and calculating that credit yourself every year, which is the paperwork burden reciprocity used to eliminate.

Is Minnesota-Wisconsin reciprocity coming back soon? Not on any confirmed timeline. Wisconsin lawmakers have advanced legislation to study reviving the agreement, but a study isn't a deal, and any actual agreement would still need sign-off from both states' revenue departments and legislatures.

Does any of this matter if I'm retired or don't commute across state lines? The reciprocity filing issue only applies if you're earning wages in one state while living in the other. If you're retired or your income doesn't cross the border, the two-return requirement doesn't apply to you at all, and the property tax versus income tax comparison becomes the whole question, still worth running against your specific income and home value.
