Utah's 45% Property-Tax Exemption: Your Long-Term Rental May Still Qualify
Program and regulatory figures verified July 24, 2026. Details change; confirm your scenario with us.
Most lender and real-estate sites tell Utah investors that rentals are taxed at 100% of value. That is only true for short-term rentals and vacant second homes. A genuine long-term rental with a tenant living in it can keep the same 45% exemption an owner-occupant gets, and that reversal is worth real money.
How Utah's primary-residence exemption actually works
Utah's Constitution and tax code let county assessors exempt 45% of the fair market value of a bona fide primary residence, plus up to one acre of land. The owner of a primary residence is therefore taxed on the remaining 55% of value. The test for "primary residence" is occupancy for at least 183 consecutive days in the year, and here is the part that changes the investment case: the exemption follows whoever occupies the home as their primary residence, not necessarily the person on the deed.
Does renting my Utah house to a tenant kill the exemption?
No, not for a genuine long-term rental, and this is the single most valuable correction on this site. Salt Lake County's Assessor states it plainly: if you own an investment property and a tenant occupies it for at least 183 consecutive days in the year, that home also likely qualifies for the exemption, and an application to the county is usually required. The tenant can even be a family member and does not have to pay rent. So a long-term tenant living there full time keeps the 45% exemption in place, and your rental is taxed on 55% of value, exactly like an owner-occupied home.
What does lose the exemption: property used for transient (short-term) residential use, condominiums in rental pools, vacation rentals, summer homes, recreational cabins, and second homes that no one occupies as a primary residence. Those are taxed on 100% of value. This is a tax and assessment matter, so confirm your specific situation with your CPA and the county assessor; we are describing the rule, not giving tax advice.
The second-home and STR penalty: roughly 1.8 times
Put the two treatments side by side and the math is stark. Take a $500,000 Salt Lake County home as a labeled hypothetical. As the owner's primary residence, or occupied by a long-term tenant, the 45% exemption applies and the county taxes only 55% of value, a $275,000 taxable base. Turn that same house into a short-term rental, or leave it as a vacant second home, and the exemption disappears: the full $500,000 is taxable. That is roughly 1.8 times the taxable base, and therefore roughly 1.8 times the property-tax bill at the same rate. The lesson for Utah investors is direct: a long-term buy-and-hold operated with a real tenant carries a materially lighter tax load inside PITIA than the same property run as a nightly rental. We build that difference into your DSCR ratio before you decide how to operate the property.
Can I claim the exemption on more than one Utah property?
Only one exemption may be claimed per household statewide, so you cannot stack it on both your own home and a part-time-occupied second home. But the rule is per household, not per owner. An owner's own home is one household, and a separately tenant-occupied rental is a different household, so each can independently qualify if each is that household's primary residence. In practice that means a landlord with several long-term rentals, each with a full-time tenant, can have the 45% exemption apply on each of those homes (one per occupying household) while also claiming it on their own residence. The county administers the applications, so file per property and keep the occupancy documentation. Full mechanics of assessment and reassessment: Utah rental property taxes.

Frequently asked questions
Does renting my Utah house to a tenant kill the property-tax exemption?
No, not for a genuine long-term rental. Utah's 45% primary-residence exemption follows whichever household occupies the home as its primary residence. A tenant living there at least 183 consecutive days can preserve it (a county application is usually required, and the tenant can be a family member). Only short-term/transient rentals and vacant second homes lose it and pay on 100% of value.
Is investment property taxed higher than a primary home in Utah?
It depends on how it is used. A short-term rental or vacant second home gets no primary-residence exemption and is taxed on 100% of value, while an owner-occupied or long-term-tenant-occupied home is taxed on 55%. So a non-qualifying investment property pays roughly 1.8 times the property-tax bill of an identical owner-occupied home at the same rate.
Can I claim the primary residence exemption on more than one Utah property?
Only one exemption per household statewide, so you cannot claim it twice for your own household. But a landlord's own home and a separately tenant-occupied rental are two different households and can each qualify independently, because the exemption tracks the occupying household's primary residence. File the county application per property and keep occupancy records.
What counts as a primary residence for the Utah exemption?
Occupancy as a primary residence for at least 183 consecutive days in the year, by whoever lives there. That can be the owner or a long-term tenant. Short-term and transient use, rental-pool condos, vacation homes, recreational cabins, and vacant second homes do not qualify. Confirm your specific situation with the county assessor and your CPA before relying on it.
