Does Iowa recognize 1031 exchanges?
Yes. An Iowa 1031 exchange works the same way for state tax as it does federally. The Iowa Department of Revenue says the Iowa Code is automatically conformed to the Internal Revenue Code, with certain exceptions, and Iowa adopted rolling conformity for tax years beginning on or after January 1, 2020. Section 1031 is not one of the exceptions, so gain deferred on your federal return is deferred on your Iowa return too.
What an exchange is worth in Iowa
In 2026 the Iowa share is 3.8% of the gain you defer, because Iowa taxes all income at a flat 3.8% under Senate File 2442. On a $1,300,000 gain, that is $49,400 of Iowa tax put off, on top of the federal capital gains tax, recapture tax and the 3.8% net investment income tax.
Owners who remember the old Iowa capital gain deduction sometimes assume they can skip the exchange and deduct the gain instead. For apartment buildings, that option is gone. The Department of Revenue’s IA 100 instructions say the deduction was repealed for most transactions on or after January 1, 2023, and the remaining exceptions cover farm real estate and breeding livestock. A 2026 apartment sale outside an exchange is taxed on the full gain in Iowa.
Owners who also hold Iowa farmland
Farmland is the one place where the Iowa capital gain deduction still competes with an exchange. Under Iowa Code 422.7(13), an owner who has held real property used in a farming business for at least 10 years and materially participated in farming for at least 10 years, or who sells it to a relative, can subtract the net capital gain on that sale from Iowa income.
The deduction removes only the Iowa tax, at 3.8%, and only on qualifying farm property. An exchange defers the federal tax as well, which is usually the larger number. Some owners sell farmland with the deduction and exchange their apartment buildings, or the reverse, in different years. Because the two choices interact, model both with your CPA before you list either property.
Debt, cash and boot in an Iowa exchange
Boot comes in two forms, and Iowa taxes both at 3.8%. Cash boot is money you take out at closing or receive from the intermediary. Mortgage boot happens when the loan paid off on the old building is larger than the debt on the new one and you do not add cash to make up the difference.
Many Iowa apartment owners carry low loan balances after years of paydown, which makes mortgage boot easy to avoid. Owners who refinanced recently need to watch it, since a $1,000,000 payoff matched with a $700,000 new loan creates $300,000 of boot unless they bring $300,000 of other cash to the purchase.
Federal 1031 rules that apply in Iowa
Iowa has no deadlines of its own, so the federal timeline controls. You have 45 days from the sale to identify replacement property in writing and 180 days, or your return due date if earlier, to close. Both properties must be real property held for business or investment, and a qualified intermediary must hold the proceeds so you never touch them.
To defer the full gain, buy replacement property of equal or greater value and reinvest all the net cash. Cash you keep, or debt paid off that you do not replace with new debt or added cash, is boot. Our guide to 1031 exchange rules covers identification rules and boot in detail, and the full 1031 exchange guide walks through the process start to finish.
Iowa withholding at closing and estimated tax
We did not find an Iowa rule on the Department of Revenue’s pages that requires a closing agent to withhold Iowa income tax from a seller’s proceeds, whether the seller lives in Iowa or not. Iowa’s concern is that the gain gets reported. Nonresidents must include 100% of the gain on Iowa real property in their Iowa-source income, and a nonresident with $1,000 or more of Iowa-source net income files an Iowa return.
In a full exchange there is no recognized gain to report beyond the exchange forms. In a partial exchange, the boot is taxable in the year of the sale, so a seller who takes cash should plan an estimated payment of 3.8% of the recognized gain.
Does Iowa have a 1031 clawback?
No. Iowa does not require an annual filing or keep a claim on deferred gain when you exchange Iowa property for property in another state. The states with tracking or clawback rules are California, Massachusetts, Montana and Oregon.
In practice, an Iowa owner who exchanges into Texas or Florida and later moves there owes Iowa nothing more on the deferred gain once the move is complete and the replacement is sold as a nonresident. Iowa taxes nonresidents on gain from property located in Iowa at the time of sale, and the replacement property is not in Iowa. Keep records of your residency change, since a move made on paper but not in fact can be questioned.
Does Iowa regulate qualified intermediaries?
No. Iowa is not one of the nine states with a law regulating exchange facilitators. Those states are California, Colorado, Connecticut, Idaho, Maine, Nevada, Oregon, Virginia and Washington.
Without a state bond or trust account rule, the protection for your exchange money is whatever your contract and your intermediary’s own practices provide. Ask before you sign:
- Will my funds sit in a separate, segregated account, and who must approve a withdrawal?
- Does the intermediary carry a fidelity bond and errors and omissions coverage, and for how much?
- Will I get statements showing the balance and any interest?
- Is the intermediary disqualified because it has been my attorney, CPA, employee or broker in the past two years?
Common 1031 exchange paths for Iowa owners
Most Iowa exchanges follow one of three paths.
Iowa to Iowa is the most common for owners who want to stay local, such as trading two older buildings in Waterloo for one newer building in Ankeny. Nothing changes on the Iowa side except your basis, which carries over to the new property.
Iowa to another state is common for owners retiring to warmer, lower-tax states. It needs no extra Iowa filings. Remember that the replacement state may tax the gain when you eventually sell there.
Out of state into Iowa brings no Iowa clawback. A seller arriving from California or Oregon may still owe that state annual tracking forms, and the gain built up there remains taxable by it.
How the 2026 property tax law affects exchange buyers
If your replacement is an Iowa apartment building, underwrite its property tax under the new rules. Senate File 2472 (2026) recreates a multiresidential property class starting with the 2027 assessment year, with a rollback 3 points above the residential rate in 2027 and 6 points above from 2028. That raises taxable value on most apartment buildings by about 6.7% in 2027 and 13.5% in 2028 if the residential rate holds steady.
Iowa reassesses in odd-numbered years, and January 1, 2027 is the next one, so a building you buy in 2026 may be revalued toward your purchase price at the same time the new rollback starts. Our page on the property tax rate in Iowa works through the numbers.
Worked example: an Iowa exchange with cash boot
An owner sells a 30-unit building in Cedar Rapids for $2,400,000 and pays $120,000 in selling costs. The building cost $1,400,000 and has $420,000 of depreciation, for an adjusted basis of $980,000, so the gain is $1,300,000.
The owner buys a $2,600,000 building in Kansas City through the intermediary, taking a new loan large enough to replace the old one, but keeps $150,000 of cash at closing. That $150,000 is boot, so $150,000 of gain is recognized and $1,150,000 is deferred. Iowa tax on the boot is $5,700 (3.8% of $150,000). The Iowa tax deferred is $43,700.
Had the owner reinvested all the cash, the full $1,300,000 would be deferred, putting off $49,400 of Iowa tax plus the federal tax. Because Iowa has no clawback, the owner files no Iowa tracking form for the Missouri building.

Timeline tips for an Iowa exchange
Line up the replacement before the relinquished property closes. The 45 days start at closing and do not stop for weekends or holidays.
- Sign the exchange agreement and assign the sale contract before closing.
- Tell your closing agent the sale is part of an exchange so proceeds go straight to the intermediary.
- If you sell late in the year, extend your return so the due date does not cut the 180 days short.
- If your Iowa building was placed in service before 2021, ask your CPA whether its Iowa basis differs from federal.
- Check an Iowa replacement’s tax bill against the 2027 rollback change before you commit.
Selling an Iowa apartment building as part of an exchange
Skyline buys apartment buildings with five or more units in Iowa. We buy directly, close on your timeline, and can work inside 1031 deadlines. We work with your intermediary on the contract assignment and can set a closing date that gives you time to find a replacement before the 45 days start.
For the tax you would owe without an exchange, see Iowa capital gains tax on real estate. The 1031 exchange calculator runs the federal side with your own numbers.
Selling? Spread the tax with seller-carry terms
If a large tax bill is what is keeping you from selling, an installment sale may help. When you carry part of the price as a note, the gain is generally reported as you receive payments instead of all in the year of sale. Some parts of the gain, such as certain depreciation recapture, can still be due up front, so run the numbers with your CPA first.
Skyline Capital Investments buys apartment buildings with five or more units and can offer seller-carry terms, or a delayed closing that fits your 1031 timeline.
