🏡 Montana Property Taxes Are Changing Again
Here’s What It Means for Your Home, Land, or Business
Montana property taxes have been a moving target the last few years — between sudden valuation spikes, surprise bills, and rebate programs you have to chase down, it’s been a bit of a mess.
Now they’re changing *again *in 2026.
If you've heard rumblings, you may have questions.
If you haven’t — now you know. Either way, you deserve a clear explanation.
This isn’t a lecture. It’s a real-world breakdown of what’s happening, who it affects, and what you need to do (if anything). We’ve kept it tight, skipped the jargon, and added Swanson Takeaways throughout — so you can understand exactly how this impacts your bottom line.
🔗 Full legislative summary here »
🏠 If You Live in Your Home Full-Time (Primary Residence)
You’re eligible for a $400 property tax rebate on your 2024 taxes — but it’s not automatic.
You have to apply in 2025.
And doing that unlocks lower tax rates on your home starting in 2026 — no second application required.
✅ What to Do:
Apply between August 15 and October 1, 2025
Application is online or by mail.
You must have lived in the home at least 7 months during 2024
🔍 Swanson Takeaway:
If this is your home, apply for the rebate in 2025.
It puts money back in your pocket now and ensures you don’t pay more in 2026.
🏘 If You Rent Property Long-Term (28+ Day Leases)
If you lease a home or apartment to long-term tenants who live there at least 7 months a year, you can qualify for the same reduced rates homeowners get — starting in 2026.
But the state won’t just assume that — you need to certify it.
✅ What to Do:
Apply between December 1, 2025 and March 1, 2026
Certify the use with the Montana Department of Revenue
Keep records showing lease terms and tenant occupancy
🔍 Swanson Takeaway:
If it’s a genuine long-term rental, claim the lower rate.
If you don’t, the state will treat it like a short-term rental — and tax it like one.
🏕 If You Own a Second Home or Short-Term Rental
This is where the increase hits hardest.
Starting in 2026, second homes, cabins, Airbnbs, and short-term rentals will be taxed at the highest residential rate.
This includes:
Vacation homes
Properties rented for fewer than 28 days at a time
Inherited homes that sit vacant
Cabins or second homes used only part of the year
Properties you split time between — even within the same household
💬 Client FAQ we expect:
“Can my spouse and I each claim a different home?”
“I live at the cabin in summer, the house in winter — doesn’t that count?”
Nope. Under the law, you can only claim one principal residence per household.
You can’t split time and claim both. The state wants to see year-round primary use, and you’ll be required to certify that when you apply for the rebate.
🚫 What to Do:
There’s no exemption or workaround here.
You can’t reclassify a second home or seasonal property to avoid the rate increase.
🔍 Swanson Takeaway:
Only one home gets the preferred rate.
If it’s not your full-time home — even if it’s family-owned or used part-time — you’ll pay the higher rate.
🌾 If You Own Agricultural Land (Especially Under 160 Acres)
If your property is 160+ acres and already classified as ag land, you’re likely good to go — you’ll get a modest tax cut, and no action is needed.
But if your parcel is under 160 acres, you’ll need to prove it’s in active agricultural use to get the same treatment.
✅ What to Do:
Visit Montana Cadastral to see how your land is currently classified
If it's labeled “non-qualified ag” but you're actively grazing, growing, or leasing:
You’ll need to show $1,500+ in ag income for 3 years
Then apply through your local DOR field office
🔍 Swanson Takeaway:
If your land is working land, get it properly classified.
It’s the difference between a fair bill and a steep overcharge.
🏢 If You Own Commercial Property
Offices, retail spaces, and income-generating properties will see higher taxes in 2026 under the new structure. There’s no form to file — the rates are baked in.
🔍 Swanson Takeaway:
You don’t need to do anything, but expect an increase.
If you run a business or own commercial rentals, budget accordingly.
✅ What Should You Do?
If you... | Action to Take |
---|---|
Live in your home full-time | Apply for the $400 rebate Aug–Oct 2025 |
Rent your property long-term | Certify it with the state Dec 2025–Mar 2026 |
Own a short-term rental or second home | Plan for a higher 2026 tax bill — no exemption available |
Own ag land under 160 acres | Apply for ag classification if income-qualified |
Own commercial property | No action required — plan for increase in 2026 |

👋 Final Thought from Bjorn
I get it — it’s hard to keep up with what’s changing, and it’s frustrating when the rules feel like they keep moving.
But here’s what I want you to hear from me directly:
You shouldn’t have to guess where you stand.
You shouldn’t need a law degree to protect your own wallet.
This isn’t about finding loopholes — it’s about knowing the rules and making smart, timely decisions. That’s what we’re here for.
