Montana levies a graduated personal income tax and a corporate income (license) tax, but it is one of only a handful of states with no general statewide sales or use tax. That single feature reshapes how owner-operated and hospitality businesses handle pricing, nexus, and compliance, while a separate set of statewide lodging taxes still applies squarely to short-term rentals, campgrounds, RV parks, and hotels. Most of these taxes are administered by the Montana Department of Revenue (DOR) through its TransAction Portal.

Montana levies a graduated personal income tax and a corporate income (license) tax, but it is one of only a handful of states with no general statewide sales or use tax. That single feature reshapes how owner-operated and hospitality businesses handle pricing, nexus, and compliance, while a separate set of statewide lodging taxes still applies squarely to short-term rentals, campgrounds, RV parks, and hotels. Most of these taxes are administered by the Montana Department of Revenue (DOR) through its TransAction Portal.
Montana imposes a graduated personal income tax on residents and on nonresidents with Montana-source income, and the state has restructured its brackets in recent years toward a simpler two-tier system tied closely to federal taxable income. Because most owner-operated businesses are pass-through entities, profits from sole proprietorships, partnerships, S corporations, and most LLCs flow through to owners and are taxed on their individual Montana returns rather than at the business level. Montana generally conforms to federal capital-gains treatment but applies its own rules and credits, so owners deciding how to draw income or recognize gains should model the Montana effect separately from the federal one.
C corporations doing business in Montana pay the corporate income tax (historically called the corporation license tax) on income apportioned to the state, with a minimum tax that applies even when a corporation shows little or no Montana income. Montana does not impose a traditional franchise or net-worth tax or a gross-receipts tax on general operating businesses. The state has also adopted a pass-through entity (PTE) tax election that lets eligible partnerships and S corporations pay Montana tax at the entity level, a workaround that can preserve a federal deduction for owners affected by the federal SALT cap; because Montana also requires pass-throughs to account for nonresident owners through withholding or composite filing, the right combination should be confirmed against current DOR guidance.
Montana has no general statewide sales or use tax, so most businesses selling goods or services within the state do not collect sales tax from customers and do not register for or remit a Montana sales tax. This also means the economic-nexus and marketplace-facilitator rules that drive remote-seller compliance in most states generally do not create a Montana sales-tax obligation, though a Montana-based seller shipping into other states can still trigger nexus and collection duties in those states. The main exceptions are narrow, locally authorized resort and local-option taxes in certain designated resort communities, plus selective taxes on specific goods such as fuel, tobacco, cannabis, and accommodations, rather than a broad sales tax.
Even without a general sales tax, Montana taxes overnight accommodations through a statewide lodging facility use tax and an accommodations sales tax that together apply to hotels, motels, short-term rentals, campgrounds, RV parks, and similar lodging for stays under 30 days. Operators are generally required to register with the Department of Revenue, collect the combined lodging tax from guests, and remit it on the assigned schedule. In addition, certain designated resort areas and resort communities can levy a local resort tax that often reaches lodging, prepared food, and tourism-related sales, so a property inside one of those jurisdictions can owe both the statewide lodging taxes and a local resort tax; hosts using online marketplaces should verify exactly which of these the platform collects, because marketplace collection may not cover every Montana lodging or resort tax.
Most Montana tax accounts, including income tax withholding, the lodging taxes, and corporate filings, are set up and managed through the Department of Revenue's TransAction Portal, while entity registration runs through the Montana Secretary of State. Lodging-tax returns are typically filed on a recurring cadence the state assigns based on volume, and income and corporate returns follow their own annual cycles with estimated payments for taxpayers above the state's thresholds. Because Montana has no sales tax to reconcile, the heaviest ongoing compliance for owner-operated businesses tends to be payroll withholding, the lodging taxes for hospitality clients, and clean documentation of any local resort-tax collections, all of which the DOR can examine on audit.
Montana's no-sales-tax status is a genuine competitive advantage for retail, e-commerce fulfillment, and any business that prices against neighboring states, but it does not exempt hospitality operators, who still face the statewide lodging taxes and, in resort towns like Whitefish, Red Lodge, Big Sky, or West Yellowstone, a local resort tax on top. The interaction between statewide lodging taxes and these local resort taxes is the single most common compliance gap for Montana STR, campground, and RV-park owners, especially seasonal operators whose revenue concentrates into the summer and winter tourism peaks. Treating each property's specific jurisdiction as its own lodging-tax question, rather than assuming a uniform statewide rule, is what keeps multi-property Montana hospitality operators clean.
Montana owner-operators work with Parikh Financial because the state's no-sales-tax structure removes one headache but leaves real complexity in lodging taxes, local resort taxes, pass-through entity elections, and multi-state nexus for anyone selling outside Montana. We handle the bookkeeping, lodging and resort-tax registration and remittance for STR, campground, and hospitality clients, and the entity-structure and PTE-election decisions that determine how much Montana tax owners actually pay.
