You can use a 1031 exchange to buy in Park City, but not to buy a second home you plan to use whenever you like. Section 1031 defers tax only on real property held for investment or business use. A vacation home used primarily for personal enjoyment does not qualify, and that is where most Park City exchanges fall apart. The workable path is the IRS safe harbor for dwelling units, which allows limited personal use alongside genuine rental use.
This is general information, not tax advice. Every exchange needs a CPA and a qualified intermediary before the first property closes.
Can you 1031 into a Park City ski home?
Yes, if you hold it as an investment. The statute defers gain on real property "held for productive use in a trade or business or for investment" exchanged for like-kind real property held the same way. Nearly all US real estate is like-kind to other US real estate, so an apartment building in Dallas can be exchanged for a Deer Valley condominium. What matters is not the property type but how you hold and use it.
Since the 2017 tax law, only real property qualifies. Furniture, equipment and other personal property no longer do, which matters in a market where many ski properties sell furnished. The furnishings have to be valued and carved out of the purchase price, and that portion is not part of the exchange. On a $6 million furnished home with $400,000 of furniture, you are exchanging into $5.6 million of real property, and the $400,000 has to come from somewhere else if you want full deferral.
What is the IRS safe harbor for vacation homes?
Revenue Procedure 2008-16 tells you exactly how much personal use is survivable. If you meet it, the IRS will not challenge whether the property was held for investment.
| Requirement | Property you sell | Property you buy |
|---|---|---|
| Ownership period | At least 24 months before the exchange | At least 24 months after the exchange |
| Rental use | Rented at fair market rent at least 14 days in each 12-month period | Same, in each of the two 12-month periods after |
| Personal use limit | No more than the greater of 14 days or 10% of the days it was rented | Same |
The 10 percent prong is what makes Park City work. A home rented 150 nights a season supports 15 personal nights. A home rented only 20 nights is capped at 14. Personal use includes use by family members and any stay at below-market rent, so a free week for your brother counts against you.
There is a Park City-specific trap inside this. The safe harbor assumes you can legally rent the property, and much of Park City cannot be rented nightly. Zoning and HOA rules prohibit short-term rentals across large parts of the market, including most of Old Town's residential streets and a majority of Promontory. Buying a home that cannot be rented nightly and then claiming investment intent is an exchange built on a plan you are not permitted to execute. Confirm rental eligibility for the specific address before you identify it, not after.
What are the deadlines?
Two clocks start when the property you are selling closes, and they run at the same time.
| Deadline | Days | Detail |
|---|---|---|
| Identify replacement property | 45 | In writing, signed, delivered to the intermediary; unambiguous addresses or legal descriptions |
| Complete the purchase | 180 | Or the due date of that year's tax return, including extensions, whichever comes first |
The 45 days are the first 45 of the 180, not an additional period. A sale closing late in the year can compress the 180 days unless you extend your return.
In practice, 45 days is the hardest part of a Park City exchange. The median Park City area sale took 37 days on market in the third quarter of 2026, and inventory above $3 million is thin. Identify before you sell, not after.
How many properties can you identify?
Three rules, and you only need to satisfy one.
- Three-property rule. Identify up to three properties, at any value.
- 200 percent rule. Identify any number, as long as their combined value is no more than twice what you sold.
- 95 percent rule. If you blow both, the exchange still works if you actually acquire 95 percent of the value you identified.
Most Park City buyers use the three-property rule and identify a backup. A Delaware Statutory Trust interest is a common third identification, because it can close on schedule if a deal falls through and can absorb leftover cash that would otherwise be taxable.
Why you cannot touch the money, and why your broker cannot hold it
The proceeds must go to a qualified intermediary before the sale closes. If you receive them, even briefly, the exchange is over and the gain is taxable.
The IRS also disqualifies your own agents from serving as intermediary, and it names real estate agents and brokers specifically, along with your accountant, attorney and anyone who worked for you in those roles within the previous two years. This is why I hand clients to an independent qualified intermediary rather than handling exchange funds.
What is boot, and how do people get taxed anyway?
Boot is anything you receive that is not like-kind property. Two kinds show up in Park City deals.
- Cash boot. Money left over because you bought cheaper than you sold.
- Mortgage boot. Debt relief. If you pay off a $2 million loan and take on only $1 million in Park City, the $1 million difference is treated as money received.
Debt you take on offsets debt you shed, so trading up in both price and financing is the clean version. Trading down produces a taxable slice even when the rest of the exchange is valid.
Your basis carries over, which means the deferred gain follows you and your depreciable basis is lower than it would be on an ordinary purchase.
Can you move into it later?
Eventually, with limits that surprise people.
- Section 121's $250,000 or $500,000 exclusion does not apply to a property acquired in a 1031 exchange until five years after you acquired it.
- Even then, the years it was a rental count as nonqualified use, and that share of the gain stays taxable.
- Depreciation you took after May 1997 is never excludable, and unrecaptured depreciation is taxed up to 25 percent.
- Higher earners may also owe the 3.8 percent net investment income tax.
The shorthand circulating online, that you rent for two years and then convert tax-free, collapses two separate rules. The two-year figure is the safe harbor for the exchange itself. The five-year rule governs the exclusion.
Does Utah tax the exchange?
Utah starts from federal adjusted gross income, so a fully deferred federal exchange produces no Utah gain. Utah is also not one of the states with a clawback provision, and it does not withhold state tax from a nonresident seller at closing, though a nonresident still files a Utah return for Utah-source income.
Your home state may be less generous. California, for example, tracks deferred gain on property exchanged out of state and taxes it later. If you are selling a California rental to buy in Park City, that clawback is the first question for your CPA.
When a straight exchange will not work
Two structures come up often here.
- Reverse exchange. You buy first and sell afterward, with an accommodation titleholder parking the property. Useful when the Park City property you want appears before your sale closes. The combined parking period is capped at 180 days.
- Improvement exchange. Exchange proceeds fund construction, but only work actually completed within 180 days counts toward the replacement value. In a market where mountain construction runs into winter, that window is tight, and new East Village deliveries scheduled for 2027 will not meet it.
The practical sequence
- Engage a qualified intermediary before your sale closes.
- Start identifying Park City property before the sale, not after.
- Confirm the rental plan meets the safe harbor, in writing, with your CPA.
- Match or exceed both price and debt.
- Keep rental records from day one; the safe harbor is a documentation exercise.
Frequently asked questions
Can I use a 1031 exchange to buy a vacation home in Park City?
Only if you hold it as an investment property rather than for personal use. The IRS safe harbor allows limited personal use: at least 14 days of fair-market rental in each of two 12-month periods, with personal use capped at the greater of 14 days or 10 percent of the days rented.
How long do I have to complete a 1031 exchange?
You have 45 days from closing on the property you sell to identify replacement property in writing, and 180 days total to complete the purchase, or your tax return due date including extensions, whichever comes first. Both clocks start at the same time.
Can my real estate agent hold my 1031 funds?
No. The IRS disqualifies your agents from acting as your intermediary, and names real estate agents and brokers specifically, along with your accountant and attorney. The funds go to an independent qualified intermediary.
Can I move into my 1031 replacement property later?
Yes, but the primary residence exclusion does not apply until five years after you acquired the property, the rental years remain taxable as nonqualified use, and depreciation taken is never excludable.
Does Utah tax a 1031 exchange?
Utah begins from federal adjusted gross income, so a fully deferred exchange creates no Utah gain, and Utah has no clawback provision. Your home state may still tax the deferred gain later.
