Utah Transient Room Tax and Short-Term Rental Tax: What STR Operators Owe

Running a short-term rental in Utah without understanding the tax structure is how operators end up with surprise assessments from the Utah State Tax Commission and their county. The total tax burden on a nightly rental isn't just what Airbnb collects at checkout — there are multiple layers, and several of them are your direct responsibility to remit.

Here's what Utah STR operators actually owe.

The Tax Stack on Short-Term Rentals

STR income in Utah is subject to several distinct taxes simultaneously:

Utah State Sales Tax: The base Utah state sales tax rate is 4.85%. Transient room rentals are subject to sales tax as a taxable service.

Utah Tourism Tax: An additional statewide tourism tax applies to transient room rentals. This is collected on top of the base sales tax.

Local Option Sales Tax: Counties and municipalities layer additional local option sales taxes on top of the state rate, bringing the combined general sales tax to between 7.19% and 7.42% depending on the county.

Utah Transient Room Tax: A separate transient room tax of up to 4.25% applies at the county level, specifically on lodging. This is distinct from the general sales tax and applies only to transient accommodations.

Local Resort Community Tax: Resort communities (Park City, Moab, St. George resort overlays) may levy additional local resort taxes on transient accommodations.

In practice, the combined tax burden on a nightly rental can reach 12% to 15% of gross revenue depending on location — a material line item in any STR underwriting model.

How the State Defines Transient Use

The Utah State Tax Commission classifies a rental as transient if the stay is less than 30 consecutive days. This 30-day threshold is the dividing line between:

• Transient lodging: Subject to transient room tax, sales tax, and local lodging taxes
• Long-term rental: Not subject to transient taxes (governed by normal landlord-tenant law)

This is why the medium-term rental (MTR) strategy — requiring a minimum 30-day stay — legally removes a property from the transient tax framework entirely. Many investors in over-regulated STR markets (Moab, Park City residential zones) pivot to 30-day minimums to avoid both the licensing burden and the transient tax filing requirements.

Property Tax Consequence of STR Classification

Here's the tax implication most investors miss: short-term rental properties are classified as non-primary use under Utah Code § 59-2-103. This means they do not qualify for the 45% Primary Residential Exemption.

A qualifying long-term rental (with a tenant in primary residence for at least 183 consecutive days) is taxed on only 55% of its assessed fair market value. An STR property is taxed on 100% of assessed value.

On a $500,000 property with a 0.6% effective tax rate:

• Long-term rental with exemption: $500,000 × 55% × 0.6% = $1,650/year
• Short-term rental without exemption: $500,000 × 100% × 0.6% = $3,000/year

That $1,350 difference represents a real carrying cost. Factor it into your STR pro forma before closing.

Income Tax: The Flat 4.5% State Rate

All rental income — including STR income — earned from Utah properties is subject to Utah's flat 4.5% state income tax rate. This applies to both resident and nonresident investors.

Short-term rental income is not treated as "passive" income by default for investors who actively manage their properties and meet the IRS material participation tests. For Utah tax purposes, net STR income flows through to the investor's Utah income tax return at the flat 4.5% rate.

Federal treatment: STR income for properties rented for fewer than 14 days per year is excluded from federal taxable income (the "Augusta Rule"). Once you rent more than 14 days, the full rental income is reportable, and you can deduct ordinary and necessary rental expenses including mortgage interest, depreciation, supplies, platform fees, and repairs.

Remittance Requirements

Utah requires STR operators to obtain a Sales Tax License from the Utah State Tax Commission before accepting the first booking. Tax must be collected from guests and remitted to the state on a regular schedule (monthly or quarterly depending on volume).

Airbnb and VRBO remit certain taxes on behalf of hosts in Utah through tax collection agreements with the state. However, local transient room taxes and resort community taxes may not be fully covered by the platform's automatic collection — verify what the platform remits versus what you are responsible for filing directly.

Grand County (Moab) and Summit County (Park City) require STR operators to register separately with their county systems and remit local lodging taxes of 10% directly — these are typically not covered by Airbnb's state tax agreement.

Park City and Moab: The High-Tax Markets

Park City / Summit County: In addition to state taxes, Park City levies a municipal resort tax on transient accommodations. Combined with county transient room tax and state sales tax, the total tax load on a Park City nightly rental is among the highest in the state.

Moab / Grand County: Grand County levies a 10% local lodging tax in addition to all state taxes. Within Moab City limits, the same 10% local tax applies. These taxes are remitted monthly directly to the county. Combined with permit fees (charged at $100 per advertised occupant per year) and state taxes, the effective tax cost per rental night in Moab is substantial.

St. George / Washington County: Washington County charges a $160 annual STR license fee plus state transient room tax and sales tax. The county requires strict compliance with off-street parking requirements — one space per bedroom — and failure to comply results in license revocation, which eliminates your legal ability to collect any rent on the property until you're reinstated.

Getting Your Tax Structure Right Before Day One

The sequence for a Utah STR investor:

1. Confirm zoning permits STR use at the specific property address
2. Apply for a Nightly Rental License or Short-Term Rental License from the municipality or county before your first listing goes live
3. Register for a Sales Tax License with the Utah State Tax Commission
4. Identify which local taxes are automatically remitted by Airbnb/VRBO versus which you must file directly
5. Set up a separate account for tax reserves (a common rule of thumb is to set aside 15% of gross revenue for combined taxes)
6. Model the property tax without the 45% residential exemption in your STR pro forma

The tax structure is knowable before you buy. Investors who underwrite it correctly aren't surprised mid-year by bills they didn't account for.
