What does it cost to set up a cleaning business in Montana?

The state's entity fee is $35 to file the Articles of Organization for Domestic Limited Liability Company. License, permit and examination fees are set by the issuing body and charged on top. We publish the entity fee because it is the one figure that is the same for every cleaning business in Montana.

Does a cleaning business need a license in Montana?

Montana issues no statewide license for a cleaning business. Local registrations and specialty permits can still apply.

Montana licenses no cleaning trade, and no board of the Business Standards Division covers it. Montana's construction contractor scheme changed on 1 January 2026 when the old contractor registration law was repealed and replaced by a new contractor licensing law, and the definition in that law covers work to construct, alter, repair, add to, subtract from, improve, move, wreck or demolish a structure attached to real estate, which does not reach janitorial cleaning. Montana levies no general sales tax; the selective sales tax in state law applies to accommodations, campgrounds and rental vehicles only.

A state that issues no license of its own is not a state with no rules. City and county business registrations, specialty endorsements and sales tax permits are set separately, and we do not track them page by page, so confirm those with Montana and with the locality you work in.

This rests on the state's own enumeration of the occupations it licenses, which does not include this trade. The source below is the record's primary citation and may not be that enumeration itself.

This records what Montana publishes, not a determination about your business. Scope, thresholds and local requirements are set by the issuing body, so confirm with them before you bid or file.

What the LLC has to do first

Almost no state licenses house cleaning as a trade. The registrations that do apply are the entity filing, sales tax where cleaning is taxable, and any local business license.

The entity filing is separate from anything the license requires. In Montana it is made with the Montana Secretary of State. File directly with the state here. The order matters wherever the license is issued to the company rather than to a person: the entity has to exist before an application can name it.

Forming an LLC as a cleaning business in Montana covers the filing itself, step by step.

Insurance Montana cleaning businesses are asked to show

Residential clients hand over a key and commercial contracts require a certificate before the first shift, so general liability is bought at the point of winning work rather than at the point of registering.

We do not publish Montana premium figures for this trade, so nothing here is a quote. Our business insurance guide for cleaning businesses covers what each policy does and does not pay for.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state licensing board publishes for this trade, with the sources this page cites. It cannot tell you whether your own work needs a licence: that turns on the scope of the job, the value of the contract, and the city or county you work in, which commonly adds its own registration on top of the state's. Confirm your own position with the board named on this page and with your local building or business licensing office before you bid or start work.
