Local Taxes in Montana

Montana Sales Tax Holidays

No state or local sales tax. During a sales tax holiday, qualifying items are sold without collecting state sales tax — and sometimes local sales tax too. Check the Montana Department of Revenue website for exact dates, eligible items, and price limits each year.

What You Can Buy Tax-Free in Montana

In Montana, virtually all retail purchases are made without sales tax. This includes clothing, electronics, furniture, vehicles, and most services. The only exceptions may be specific excise taxes on items like tobacco, fuel, or alcohol, which are taxed separately from sales tax in every state.

Tips for Accurate Sales Tax Calculations

Always confirm the exact local rate for your specific city or county — the combined average (0%) is a statewide mean and may differ from your actual checkout rate. Large purchases like vehicles, appliances, or electronics are where the difference between state-only and combined rates matters most. Keep receipts that show the tax rate used; this helps verify correct tax was charged and supports any refund claims for exempt purchases. If you are making a business purchase, check whether your state offers a sales tax exemption certificate to avoid paying tax on resale items.
