1031 Exchange in Wisconsin

By Skyline Capital Investments · Updated October 26, 2026 · 7 min read

Does Wisconsin recognize 1031 exchanges?

Yes. A Wisconsin 1031 exchange works the same way for state tax as for federal tax, because Wisconsin follows the Internal Revenue Code as amended to December 31, 2022, according to the Department of Revenue’s Wisconsin Tax Bulletin 234. Section 1031 in that version covers real property held for investment or business use, the same rule the IRS applies.

The state tax at stake is smaller than in some states but still real. Wisconsin taxes 70% of a long-term gain at rates up to 7.65%, so deferring a $1,000,000 gain at the top rate defers about $53,550 of Wisconsin tax on top of the federal amount.

Federal 1031 rules that apply in Wisconsin

Wisconsin sets no extra deadlines. You have 45 days from closing to identify replacement property in writing and 180 days, or your tax return due date if that comes sooner, to acquire it. A qualified intermediary must hold the sale proceeds so you never have access to them.

To defer the full gain, buy replacement property of equal or greater value and reinvest every dollar of net proceeds. Cash you keep and debt you are relieved of without replacing it are boot, taxed in the year of sale by both the IRS and Wisconsin. Our guide to 1031 exchange rules explains identification and boot in detail, and the complete 1031 exchange guide covers the full process.

How boot is taxed in Wisconsin

Boot that is long-term capital gain gets the same 30% Wisconsin deduction as any other long-term gain, so only 70% of it is taxed. That makes a partial exchange somewhat cheaper at the state level than the headline 7.65% rate suggests.

The deduction applies to net capital gain from assets held more than one year. Boot that the federal return treats as ordinary income, such as Section 1245 recapture on personal property identified in a cost segregation study, does not get the deduction. For an exchange, the federal rules generally let you count the time you held the old property toward the holding period of the new one, which matters when you later sell the replacement.

Wisconsin basis may also differ from federal basis. Wisconsin follows the Code as of January 1, 2014 for depreciation and did not adopt later federal bonus depreciation, including the 2025 law, so the Wisconsin basis carried into your replacement property can be higher than the federal figure. Keep a separate Wisconsin depreciation schedule for the replacement.

Does Wisconsin have a 1031 clawback?

No. Wisconsin is not one of the four states with a clawback or tracking rule for exchanges into other states. Those states are California, Massachusetts, Montana and Oregon, and each keeps some claim on deferred gain after the money leaves the state, through annual filings or a consent to jurisdiction.

For a Wisconsin resident, the absence of a clawback matters less than it sounds, because Wisconsin taxes residents on their income wherever it comes from. If you trade into an Arizona building and later sell it in a taxable sale while still living in Wisconsin, the gain, including the deferred Wisconsin gain, is taxed by Wisconsin then. The difference shows up for owners who exchange out of Wisconsin and later become residents of another state.

Withholding and estimated tax on a Wisconsin exchange

The Department of Revenue’s nonresident guidance says gain from selling Wisconsin real estate must be reported to Wisconsin whatever the owner’s residence, and that estimated tax on the gain is due at the time of the sale unless it is reported on the installment method. In an exchange, only the recognized gain, mainly boot, is taxable that year, so that is the figure your estimated payment is based on.

When the property is held in a partnership, LLC or S corporation with nonresident owners, the entity must withhold Wisconsin tax on Wisconsin income allocated to those owners under section 71.775, at 7.65% for individuals, estates and trusts and 7.9% for partnerships and corporations, reported on Form PW-1. No withholding is needed for an owner whose share of Wisconsin income is under $1,000.

• Run the recognized gain for each owner before closing, so estimated payments and any PW-1 withholding match the boot, not the full price.
• A full exchange with no boot leaves no recognized gain to pay estimated tax on.
• Ask your CPA how drop-and-swap or tenant-in-common restructurings affect who is the taxpayer before you sign.

Does Wisconsin regulate qualified intermediaries?

No. Wisconsin is not one of the nine states with a qualified intermediary law, which are California, Colorado, Connecticut, Idaho, Maine, Nevada, Oregon, Virginia and Washington. Those laws set bonding, insurance or account rules for exchange companies.

That leaves the protection of your money to your contract and your questions. Ask for written proof of a fidelity bond and errors and omissions coverage, whether funds sit in a separate account in your name, who must sign to move money and how often you get statements. The intermediary cannot be someone who was your agent in the past two years, such as your attorney, CPA, employee or real estate broker.

Common 1031 exchange paths for Wisconsin owners

Wisconsin exchanges tend to follow one of three paths.

Wisconsin to Wisconsin is the most common for owners who know their local market. Trading a set of Milwaukee duplexes for a larger building in Madison or Waukesha keeps the property, the tax return and the landlord-tenant rules the same.

Wisconsin to another state works with no Wisconsin tracking filing. Owners heading to Arizona, Florida or Texas often pair the exchange with a planned move, and the tax result depends on where they live when they eventually sell.

Another state into Wisconsin brings no Wisconsin clawback, but an owner selling in California, Massachusetts, Montana or Oregon may still owe filings or consent to that state on the deferred gain.

Family and related-party exchanges

Wisconsin owners often hold buildings with siblings, children or a family LLC, and those deals need extra care. Under Section 1031(f), if you exchange property with a related person, such as a family member or an entity you control, and either side disposes of its property within two years, the deferred gain generally becomes taxable. Wisconsin follows the same rule because it follows Section 1031.

Buying your replacement from a relative is also restricted by the IRS. If a family deal is part of the plan, raise it with your CPA before you list, not after you have identified the property.

Worked example: a Wisconsin exchange into Arizona

The Wisconsin tax uses the 7.65% top rate, assuming the owners’ other income already puts them in that bracket.

A married couple in Green Bay sells an 18-unit building in Appleton for $2,000,000. After $100,000 of selling costs and with an adjusted Wisconsin basis of $750,000, the gain is $1,150,000, all long-term and all from straight-line depreciation and appreciation. The $800,000 loan is paid off, leaving $1,100,000. They keep $120,000 at closing and the intermediary receives $980,000.

They buy a $2,200,000 building in Phoenix with the $980,000 and a new $1,220,000 loan. The $120,000 they kept is boot, so $120,000 of gain is recognized and $1,030,000 is deferred. After the 30% deduction, $84,000 of the boot is taxable in Wisconsin, for about $6,426 of state tax. The Wisconsin tax deferred on the remaining $1,030,000 is about $55,157.

Wisconsin requires no annual filing because the replacement is in Arizona. If the couple still lives in Wisconsin when they sell the Phoenix building in a taxable sale, Wisconsin taxes that gain then. Had they reinvested all $1,100,000 and kept no cash, the full $1,150,000 would be deferred, along with about $61,583 of Wisconsin tax.

Timeline tips for a Wisconsin exchange

Pick your intermediary and sign the exchange agreement before closing. The 45-day clock starts the day the sale closes, and Wisconsin owners buying in an unfamiliar out-of-state market often need every one of those days.

• Assign the sale contract to the intermediary before closing, not at the table.
• Line up financing for the replacement early, since replacing the old loan helps avoid debt-relief boot.
• If you sell late in the year, extend your return so the due date does not cut the 180 days short.
• Keep your Wisconsin depreciation schedule with the exchange file and carry it to the replacement.
• If the property is in an LLC with out-of-state members, settle PW-1 withholding on any boot before closing.

Selling a Wisconsin apartment building as part of an exchange

We work with your intermediary on the contract assignment and can set a closing date that leaves room to identify the replacement before your 45 days start.
