Helena permits STR broadly across residential and commercial zones with a city business license + state lodging tax registration. No cap, no primary-residence requirement. As the state capital, Helena draws government + legislative-session demand alongside leisure tourism. Lewis and Clark County (unincorporated areas: East Helena, Lincoln, Augusta) operates parallel registration.
Operators must hold a short-term rental permit before listing. See the official permit portal.
City of Helena Community Development handles STR business licensing. Montana Department of Revenue collects the 4% Lodging Facility Use Tax + 4% accommodations sales tax. Application requires Montana lodging tax registration, designated local contact, life-safety self-certification, and proof of insurance. Annual renewal. Enforcement is complaint-driven. The Helena STR market is smaller than Whitefish/Bozeman/Big Sky/Missoula and ordinances are less actively debated, but track council agendas as the market grows.
Combined short-term lodging tax in Helena is approximately 8.000% of gross nightly revenue (state sales + state TRT + local TRT + applicable resort/city options).
Montana Lodging Facility Use Tax 4% + Montana sales tax on accommodations 4% — combined ~8.0% on transient lodging (Helena does not have a local resort tax)
Verify the current combined rate via the Utah State Tax Commission before remitting — rates drift quarterly.
