What catches Montana business owners off guard
Montana requires LLCs to file an annual report by April 15 with a $20 filing fee — one of the lowest in the nation. But Montana’s reputation as a no-sales-tax state creates a specific compliance trap for business owners who relocate from other states. While Montana genuinely has no general sales tax, it does have a resort tax in certain tourist-heavy areas, and businesses in those zones must collect and remit it. Owners who assumed “no sales tax” meant no transaction-based tax compliance have been caught off guard.
Montana also has an unusual vehicle registration advantage that attracts out-of-state buyers — forming a Montana LLC to register vehicles and avoid sales tax in their home state. While this practice has become widespread, it exists in a legal gray area and several states have begun cracking down on it. If your Montana LLC was formed primarily for vehicle registration, understanding the compliance and legal risks is critical.
Montana's no-sales-tax reputation hides compliance traps that catch new owners.

Quick-Start Teaser
Avoid the biggest traps new owners face – from my 27-page full guide
PHASE 1: BUSINESS PLANNING & LEGAL STRUCTURE
Validate idea, choose entity (LLC/S-Corp/etc.), register with Secretary of State, get EIN, DBA, operating agreement/bylaws.
■ TRAP ALERT: Picking default LLC when S-Corp would save on SE taxes → MT’s top rate recently reduced to 5.65% (2026) but SE tax still adds 15.3% — S-Corp election saves thousands at higher profits.
PHASE 2: STATE & LOCAL REGISTRATIONS
Register for state tax accounts, sales/gross receipts tax, local licenses and permits, unemployment insurance, new hire reporting.
■ TRAP ALERT: Missing the annual report ($20, due April 15) → Administrative dissolution and loss of LLC status.
PHASE 3: FEDERAL COMPLIANCE
Check federal licenses, set up payroll taxes (EFTPS), I-9 for hires, workplace safety (OSHA/state plan).
■ TRAP ALERT: Commingling personal and business funds → Pierces the corporate veil and exposes your personal assets to lawsuits and debts.
PHASE 4: INSURANCE & RISK MANAGEMENT
General liability, workers’ comp (required in most states), state-mandated benefits, standard contracts/agreements.
■ TRAP ALERT: Skipping workers’ comp — Montana requires coverage for ALL employers with 1+ employee → Criminal penalties and personal liability; MT has a competitive state fund option.
PHASE 5: FINANCIAL SETUP & TAX COMPLIANCE
Open dedicated business bank account, set up bookkeeping/accounting systems.
■ TRAP ALERT: Not understanding Montana has NO SALES TAX (one of only 5 states) → While great for retail, MT’s lack of sales tax means the state relies heavily on income and property taxes — budget accordingly.
PHASE 6: OPERATIONS & ONGOING COMPLIANCE
Navigate ongoing taxes/regulations, maintain compliance calendar, annual filings.
■ TRAP ALERT: Missing ongoing filings or poor record-keeping → Escalating penalties, audits, or forced dissolution.
