Park City Property Taxes: The 45% Break Most Second Home Buyers Never Get (And the Deadline That Just Passed)

I get some version of this question every single week. A buyer is comparing a home in Park City to something in California, Texas, or Florida, they look up Utah's property tax rate, and they come away thinking Summit County is one of the cheapest places in the country to own a home. Then they close on a second home here, the tax notice shows up in November, and the number is nothing like what they penciled out.

The gap almost never comes from the tax rate. It comes from a single line in the Utah State Constitution that most out of state buyers have never heard of, and one deadline that quietly passed three days ago.

What Is Utah's 45% Primary Residence Exemption?

Utah does something unusual. Under Article XIII, Section 3 of the Utah State Constitution, county assessors exempt 45 percent of the fair market value of a residential property, plus up to one acre of land, from taxation. If you qualify, your home is taxed on 55 percent of its market value instead of 100 percent.

The Utah State Tax Commission is direct about the limits. The exemption applies to a primary residence. It does not apply to property used for transient residential use, and it does not apply to condominiums in rental pools. That last clause matters enormously in a resort town.

Most homes in Utah get the exemption automatically, because most homes in Utah are somebody's primary residence. Park City is not most of Utah.

How Much More Does a Second Home Cost in Property Tax?

Here is the arithmetic, and it is simpler than people expect. A primary residence is taxed on 55 percent of value. A second home is taxed on 100 percent. That means the second home owner pays tax on roughly 1.8 times the base, which works out to about 82 percent more in annual property tax on an identical property at an identical rate.

Put real Park City numbers on it. According to the Park City Board of REALTORS Q2 2026 market report, the median single family sale price inside Park City limits (Areas 1 through 9) was $3.8 million. As a primary residence, that home is taxed on about $2.09 million. As a second home, it is taxed on the full $3.8 million. That is roughly $1.71 million of additional taxable value sitting on the same house, every year.

Run it down valley and the dollars shrink but the percentage does not. Heber Valley's Q2 2026 single family median was $940,000, so the exemption is worth about $423,000 of taxable value there. Snyderville Basin came in at $2.25 million and Jordanelle at $3.669 million.

I am deliberately not quoting you a dollar figure for the tax itself. Summit County has more than sixty separate tax areas and your rate depends on which one your parcel sits in, so the only number worth trusting is the one on your own notice. The Summit County Treasurer can confirm the exact rate for your address.

Who Actually Qualifies for the Exemption in Summit County?

Summit County's own rules are stricter and more specific than the state summary, and this is where people get tripped up.

You qualify if you are a Utah domiciled resident living in the property full time. The home must be occupied by that domiciled resident for 183 consecutive days of the calendar year. Not 183 days scattered across the year. Consecutive.

You also qualify, and this is the part almost nobody knows, if you rent the property to a Utah domiciled resident tenant year round. A landlord with a real annual tenant in Prospector or Silver Springs can hold the exemption on that unit. That is a meaningful carve out for anyone weighing long term rental against nightly rental in this market.

You do not qualify if the property is a vacation home, or if it is rented nightly or short term. Summit County spells this out plainly. The county FAQ also takes on the obvious workaround directly: a property rented long term for most of the year but flipped to nightly for Sundance and ski season is its own question, and one worth asking the Assessor about before you assume the answer.

The Park City Tax Deadline That Just Passed

Summit County's deadline for Primary Residence Exemption applications was September 15, 2026. That was three days ago.

Per the county, any application received after that date is considered for the next calendar year. So if you moved into your Park Meadows or Old Town home this summer, became a Utah resident, and never filed the paperwork, you are paying the non primary rate on this year's bill. You are not out of luck permanently. You are out of luck for 2026.

Wasatch County runs on a different calendar, which catches Heber City, Midway, and much of the Jordanelle side. There the standard application deadline is April 30, and applications after May 1 get processed as a Board of Equalization appeal with a September 15 filing cutoff. Two counties, one metro market, two sets of dates. If you own on both sides of that line, you have to track both.

What Happens Next With Your 2026 Tax Bill

The Summit County Treasurer's published calendar for the rest of this year runs like this. Tax bills mail to property owners on October 25, 2026. Payment is due November 30, 2026. A 1 percent penalty hits unpaid balances on December 1. December 31 is the final deadline for 2026 tax relief applications and all supporting documentation. After January 31, 2027, an additional 1.5 percent penalty applies and interest starts accruing back to January 1.

Your valuation notice from late July already told you whether you have the exemption, and your November tax notice will confirm it. If your taxable value equals your full market value, you do not have it. That is the fastest way to check.

How This Should Change the Way You Shop Park City

If you are buying a second home in Deer Valley, Empire Pass, Promontory, or Canyons Village, build the non exempt number into your carrying cost from day one. Do not let anyone hand you last year's tax figure from a seller who was a full time resident, because your bill on the same house will not look like theirs.

If you are relocating here full time, the exemption is real money, and it is worth organizing your move and your residency paperwork around the filing window rather than getting to it whenever the boxes are unpacked.

And if you are an investor choosing between a nightly rental in Old Town and a long term rental in Snyderville Basin or Kamas, the tax treatment belongs in that spreadsheet right next to the rent projections. Nightly rental income is higher. The property tax base underneath it is also 45 percent larger. Those two facts have to be weighed against each other, not looked at one at a time.

Park City Property Tax FAQ

Does my Park City ski condo qualify for the primary residence exemption?

Not if it sits in a rental pool or is rented nightly. The Utah State Tax Commission specifically excludes condominiums used in rental pools and property used for transient residential use.

I split my year between Park City and somewhere else. Can I still get it?

Summit County requires occupancy by a Utah domiciled resident for 183 consecutive days in the calendar year. Part year occupancy that never hits a consecutive 183 day stretch does not meet the county's stated standard.

Can I get the exemption on a home I rent out?

In Summit County, yes, if you rent it year round to a Utah domiciled resident tenant. Nightly and short term rentals do not qualify.

I missed the September 15 deadline. What now?

Summit County states that applications received after the September 15 appeal deadline are considered for the next calendar year. File anyway so you are in the queue, and talk to the Assessor's office about your specific situation.

Is it different in Heber City or Midway?

The 45 percent exemption itself is a statewide constitutional provision, so the benefit is the same. The filing calendar is not. Wasatch County's standard deadline is April 30, with a September 15 Board of Equalization path after May 1.

None of this is tax or legal advice, and your parcel can have wrinkles a blog post cannot anticipate. Confirm your own situation with the Summit County or Wasatch County Assessor before you rely on any of it.
