Montana Property Taxes Explained for Out-of-State Buyers

The short answer: Starting with 2026 tax bills, Montana taxes homes differently depending on how they are used. A primary residence or long-term rental that qualifies for “homestead” status is taxed at tiered rates that start at 0.76 percent of market value. Second homes and short-term rentals are taxed at a flat 1.90 percent. The state projected that the average owner-occupied home would pay about 18 percent less than in 2024, while homes without homestead status would pay about 68 percent more. If you move here and live in your home at least seven months a year, you must apply for homestead status to get the lower rate.

This is one of the most important things I explain to relocating buyers in 2026, because it can change your monthly payment by hundreds of dollars. Here is how it works in plain English. I am a real estate agent, not a tax professional, so confirm your specific situation with the Montana Department of Revenue or a tax advisor.

How Montana property tax works

Your Montana property tax bill comes from three pieces:

Market value. The Department of Revenue appraises your property.
Tax rate. The state applies a tax rate to the market value to get your taxable value. This is the part that changed for 2026.
Mill levies. Local governments, school districts, and other taxing jurisdictions apply their mill levies to your taxable value. Mill levies vary by location, which is why two homes with the same value in Bozeman and Livingston can have different bills.

Your bill equals taxable value multiplied by the total mill levy, divided by 1,000.

What changed in 2026

The 2025 Montana Legislature passed Senate Bill 542 and House Bill 231, signed by Gov. Greg Gianforte in May 2025. The new system splits residential property into two groups.

Homestead and long-term rental property: tiered rates

According to a 2026 summary of the new rates, homestead property is taxed in tiers based on the statewide median home value, estimated at about $378,000:

Value up to the median: 0.76 percent
Value between 1 and 2 times the median: 0.90 percent
Value between 2 and 4 times the median: 1.10 percent
Value above 4 times the median: 1.90 percent

Second homes and short-term rentals: flat rate

Residential property that does not qualify for homestead status is taxed at a flat 1.90 percent of market value, regardless of value.

The Department of Revenue publishes the official rates and the current median each year, so check its rates page for the figures that apply to your bill.

An example: same house, two tax treatments

Here is how the taxable value works on an $800,000 home, using the rates above and the estimated $378,000 median.

As a homestead

First $378,000 at 0.76 percent: about $2,873
Next $378,000 (up to $756,000) at 0.90 percent: about $3,402
Remaining $44,000 at 1.10 percent: about $484
Taxable value: about $6,759

As a second home

$800,000 at 1.90 percent
Taxable value: $15,200

The second-home taxable value is more than double the homestead figure. Because your bill is taxable value times local mill levies, the bill would be more than double too, before any other adjustments. That is why claiming homestead status matters so much.

Who qualifies for homestead status?

Based on Montana Free Press’s explanation of the new law:

Homeowners who live in the home at least seven months a year.
Landlords who rent the home on long-term leases of at least 28 days at a time for at least seven months a year. Short-term vacation rentals do not qualify.
Ownership type: homes owned by individuals, couples, or revocable trusts can qualify. Owner-occupied homes held in an LLC or an irrevocable trust do not. Long-term rentals can qualify regardless of ownership structure.
Multi-unit properties are evaluated unit by unit.
Homes on agricultural land follow separate rules, so ask the Department of Revenue.

How to apply as a new Montana homeowner

Homestead status does not transfer with a sale. When you buy, you need to apply in your own name.

Move in and make it your principal residence.
Gather your information: your Montana driver’s license, the property address, and the parcel number from your closing documents.
Apply online through the state’s homestead portal at homestead.mt.gov, or at a Department of Revenue field office.
Watch the deadline. For 2026 tax bills, the application window closed March 1, 2026. Expect a similar deadline each year, and if you buy after the deadline, contact the Department of Revenue right away to ask how your property will be classified.
Check your notice. Make sure your assessment notice shows the property as homestead.

Qualification lasts until you sell, move, or claim homestead on another property. False claims carry penalties of up to three times the tax saved, plus possible criminal charges, so only claim the home you actually live in.

What this means for different buyers

Full-time movers

Good news. If you are relocating to live here year-round, the 2026 system generally works in your favor. Apply for homestead promptly.

Second-home buyers

Budget for higher taxes than past bills suggest. Ask for a tax estimate based on non-homestead rates, not the seller’s current bill, which may reflect homestead status.

Short-term rental investors

Short-term rentals pay the 1.90 percent rate. Factor that into your projected returns, especially in Gardiner, Big Sky, or Paradise Valley, where vacation rentals are common.

Snowbirds

If you split the year, count your months carefully. Homestead requires at least seven months in the home.

Common mistakes I see

Relying on the seller’s tax bill. The seller’s bill reflects their status. Yours may be different.
Buying in an LLC without checking. An owner-occupied home in an LLC does not qualify for homestead.
Forgetting to apply. Missing the deadline can mean paying the higher rate until the record is corrected.
Ignoring mill levies. The same home value can produce different bills in different towns and school districts.

Other Montana taxes worth knowing

No general sales tax. Montana has no statewide sales tax.
Income tax. Montana’s top rate is scheduled to drop to 5.65 percent for the 2026 tax year and 5.4 percent for 2027, according to the Tax Foundation.

How I help

When I write offers for relocating buyers, I flag how the property is currently taxed, help estimate what your taxes will look like under your intended use, and remind you to apply for homestead after closing. Whether you visit before you buy or buy entirely remotely, nothing about your tax status should catch you by surprise.

Your first year of Montana property taxes

Here is roughly how property taxes play out for a new homeowner. Exact dates and amounts come from your county treasurer, so confirm the details for your property.

At closing: property taxes are usually prorated between buyer and seller. Your closing statement will show the split.
Right after you move in: apply for homestead status through the state if the home is your primary residence.
When your assessment notice arrives: check that the property shows the correct classification and value. If something looks wrong, contact the Department of Revenue promptly, because appeal windows are limited.
When your tax bill arrives: Montana property taxes are commonly billed by the county and paid in two installments. If your lender escrows taxes, your monthly payment covers them.
Each year after: watch for changes in mill levies from local school, city, and county budgets, which can raise or lower your bill even if your home’s value is unchanged.

Questions to ask before you buy

How is the property taxed today, homestead or non-homestead?
What would my estimated taxes be under my intended use?
What are the local mill levies for this address, and are any new levies on the ballot?
Is any part of the property classified as agricultural, and how does that affect the home?
If I am buying a short-term rental, what will the 1.90 percent rate do to my projected returns?

Special situations

Buying in a trust or LLC. If you plan to live in the home, check the ownership structure with an attorney or tax advisor before closing. Owner-occupied homes held in an LLC or irrevocable trust do not qualify for homestead status, while revocable trusts can.

Moving in partway through the year. If you close after the application deadline, contact the Department of Revenue right away to ask how your property will be classified for that tax year.

Keeping your old home as a rental. If you are moving here and renting out a home in another state, your Montana home’s status is separate. Focus on qualifying the home you actually live in.
