How is an LLC Taxed in Montana?
By default:
Single-Member LLCs are taxed like Sole Proprietorships.
Multi-Member LLCs are taxed like Partnerships.
Profits pass through to your personal tax return — so the LLC doesn’t pay federal income taxes itself.
You can also elect to be taxed as a C-Corp or S-Corp if it’s a better fit for your situation.
For state taxes, Montana generally aligns with federal treatment. Learn more on the Montana Department of Revenue website.
