Vacant land: why no reduced rate exists, in any year
Most sources will not tell a bare-land owner plainly that there is no form to file. There is not. What there sometimes is, is a classification argument — and unlike everything else in property tax, it never expires.
The short version
Both reduced rates require a dwelling. A vacant residential lot qualifies for neither, in 2026 or in any future year, and no application will change that. It sits at 1.9%.
That is the honest answer, and most sources will not give it to you. The lever that does sometimes exist is not the rate at all — it is the classification.
Why the door is closed
MCA 15-6-402 defines a long-term rental, and the definition begins with the structure:
… a single-family dwelling unit, unit of a multiple-unit dwelling, trailer, manufactured home, or mobile home and the parcel on which the long-term rental improvements are located, but not including any contiguous or adjacent parcels…
There is nothing on bare ground to rent as a residence, so the rental claim cannot reach it. The homestead claim asks you to live there at least seven months a year, which a vacant lot also cannot satisfy. Two doors, both shut, for a structural reason rather than a procedural one.
The adjacent-parcel clause catches people with a house next door
Read that last phrase again: “but not including any contiguous or adjacent parcels.” If your house is one geocode and the acreage behind it is another, the claim on the house does not extend to the land. The bare parcel keeps paying 1.9% even though you own both, live on one, and have always thought of them as one place.
This is worth checking before you count a portfolio saving. Two parcel numbers on one driveway is a very common arrangement in Montana.
What it costs
On a $200,000 lot, the 2026 change looks like this in taxable value:
| Tax year | Rate | Taxable value |
|---|---|---|
| 2025 | 0.76% | $1,520 |
| 2026 | 1.9% | $3,800 |
| Increase | $2,280 |
Two and a half times, with no election available to undo it. And note what the 2025 row proves: bare land was on 0.76% last year, and bare land can never have held a homestead. So that rate was never an exemption anyone qualified for — it was simply the general residential rate. You did not lose anything you had; a rate that used to be automatic became conditional, and vacant land cannot meet the condition.
Check this first — it moves more than anything else
Before accepting the residential answer, confirm the parcel is genuinely residential and genuinely vacant. Two checks are worth making:
Is there a mobile or manufactured home on it?
A mobile or manufactured home is frequently assessed as its own record, separate from the land. That means the land parcel can read as vacant in the public record while a dwelling genuinely sits on it — and a dwelling is exactly what the reduced rates require. Mobile-home owners have been the group most often caught out by the opt-in change, from both directions.
Should it be agricultural or forest land instead of residential?
Class three agricultural land is taxed on productive capacity rather than market value, and class ten forest land on forest productivity. Both produce dramatically lower taxable values than a residential market-value assessment on the same ground.
Under MCA 15-7-202, contiguous parcels totalling 160 acres or more under one ownership are eligible as agricultural land. Between 20 and 160 acres, and below 20 acres, land actively devoted to agricultural use is eligible if it produces at least $1,500 in annual gross income from agricultural products. Below 160 acres the department may not classify land as agricultural unless the owner has applied.
A classification argument has no deadline
This matters more than it sounds. The rate is fixed by statute and the mills are set by jurisdictions, but classification is one of only two things that can ever be contested — and under MCA 15-8-601 a genuine classification error is correctable by the department whenever it is found, without an open appeal window.
So a bare-land owner who has missed every deadline in the calendar still has this one available. Options include asking the department to review the classification, applying for agricultural classification if the use supports it, or having the notice reviewed before you decide which.
If it really is a vacant residential lot
Then the options are the honest short list: build on it — a dwelling opens both doors, and a rental claim is available from the year the tenancy meets the tests; sell it; or pay the 1.9% and treat it as a holding cost. A lot held for a future build now costs meaningfully more per year to hold than it did in 2025, and that belongs in the arithmetic of whether to keep waiting.
What is not worth doing is appealing. If the market value is right and only the rate moved, an appeal has nothing to work with — the rate is statutory, and the letter the department sent about it is not an appealable determination. Spend the effort on the classification question instead.

Montana taxable values jumped for 2026 and most of it is not an error. HB 231 made the reduced rates opt-in: the 0.76% rate that used to apply to everyone now requires an application. What changed, what you can still do, and what is not worth fighting.

There is no relief program for a Montana second home as such — HB 231 left cabins and short-term rentals at the 1.9% default deliberately. The four options, costed: pay it, convert to a long-term rental, move in, or sell. Plus the seasonal lease most owners miss.

Where your own parcel stands
The rate check is free and takes about ten seconds — look up any Montana property and see which rate applies, which reduced rate it could qualify for, and the gap between them. No email required. If you would rather someone went through the whole notice, that is what we do.
