Monthly RV rental, and the day the tax stops
Reviewed by Ben Kiser, RV rental operator and fleet consultant.
Utah Code 59-12-102(135) defines a short-term rental as one of "less than 30 consecutive days", so at 30 consecutive days the state's 2.5 percent and Salt Lake County's 7 percent stop applying. Below that line those 9.5 points sit on top of 8.45 percent sales tax.
It is not a discount a host grants, it is a definition that no longer fits. A 29 night booking and a 30 night booking at the same nightly rate are taxed differently, and the longer one can cost less in total. Write the 30 consecutive days into the booking rather than assuming the host will read it that way.
The supply side is the constraint. 28 of the 610 listings measured in this market on 18 September 2026 were flagged as accepting long-term stays, which is 4.6 percent. Search that 28 first, because a host who will not take 30 nights cannot give you the exemption at any price.
Local rule
Day 30 is a statutory line, not a negotiation
Utah Code 59-12-102(135) defines a short-term rental as one of less than 30 consecutive days. Below that the state 2.5 percent and Salt Lake County 7 percent motor vehicle rental taxes apply. At 30 and above they do not. Separately, a motorhome rated at 14,001 lbs GVWR or more is exempt at any length of rental under 59-12-1201(5)(a).

- +The unit's GVWR in writing, which may exempt the whole rental regardless of length
- +A written booking of 30 consecutive days or more where that is the plan
- +A site with a monthly rate, since no Utah national park campground allows a stay that long

Start with the road, then the rig
The length band is far harder to change than the dates. Browse current listings near Salt Lake City, then ask the host for the width mirror to mirror before you pay.
