The homestead reduced rate: who qualifies, and how to claim it
The homestead claim is the highest-value, most-missed item in Montana property tax. It is free, it is an application rather than an appeal, and one of its four conditions rules out a whole category of owners no matter what they file.
The short version
If you own your home and live in it at least 7 months a year, the homestead claim moves you off the 1.9% default and onto graduated bands that start at 0.76%. It is an application, not an appeal, and it is free.
The window for the 2027 tax year closes March 1, 2027. Check first whether a claim is already on file — many are, and the check takes a minute at homestead.mt.gov.
The four tests
These are the Department of Revenue’s own criteria, as stated in the letter it mailed to non-enrolled owners in September 2026. All four have to hold.
1. It is your principal residence, 7+ months a year
“Principal” is doing real work here — one per owner. A couple with two houses gets one homestead between them, not one each, and the second house sits at the default rate unless it can qualify as a long-term rental.
2. It is owned in your individual name(s), or by a grantor revocable trust
This is the test that surprises people, and it is structural rather than procedural. MCA 15-6-405 provides that class four residential property owned by an entity is not eligible, while “the trustee of a grantor revocable trust may apply… on behalf of the trust.”
So a house held in an LLC, corporation, partnership or irrevocable trust cannot hold a homestead no matter who lives in it. That is a floor, not an oversight — no amount of paperwork fixes it. The long-term rental rate is the only reduced rate an entity-held residence can reach, and it can reach it in full.
3. You are current on the property taxes
A delinquency can cost you the reduced rate on top of the penalty and interest. Worth knowing before letting a bill ride into the next year.
4. You filed — which is the entire point
Before 2026 nothing had to be filed, because the reduced rate applied to residential property generally. HB 231 made it opt-in. If your taxable value jumped roughly two-and-a-half times on an unchanged market value, an unfiled claim is the first thing to rule out.
What it is worth
The reduced rate is not a single number — it is four bands that fill in order, and the first is pegged to the median residential value for the cycle ($386,000 for 2026). A house sitting exactly at that median looks like this:
| Band | Market value in it | Rate | Taxable value |
|---|---|---|---|
| First band | $386,000 | 0.76% | $2,934 |
| Total | $386,000 | 0.76% | $2,934 |
The same house with no claim on file is taxed at the flat 1.9% default — $7,334 of taxable value. So the claim is worth $4,400 of taxable value on a median home. What that saves in dollars depends on your local mills, which nobody can tell you from an address alone — the free rate check will show you the taxable-value gap on your own parcel.
How and when to apply
The application is made electronically or by mail on a form provided by the department, between December 1 of the immediately preceding year and March 1, with a written declaration under penalty of perjury, the property’s geocode or identifier, and the applicant’s social security number.
The statutory window and the real window are not the same
The code says December 1. For the 2027 tax year the department opened applications on 4 May 2026 — roughly seven months early. Anyone calendaring from the statute alone starts late by default.
It is open now, and it closes March 1, 2027.
Four things about the deadline that are not obvious
Missing it costs a year, not the program
An application postmarked after March 1 is not thrown out — under MCA 15-6-405 it “applies to the following tax year.” You lose one year of the reduced rate, not your eligibility.
The saving shows up one bill later
A claim filed by March 1, 2027 reduces the 2027taxable value, which lands on the treasurer’s bill in the fall of 2027. There is no mid-year cure, and no adjustment to a bill already issued.
Once granted it rolls over — until something changes
The rate stays effective until ownership changes, the use changes, or you claim a different principal residence. A transfer into an LLC, an inheritance or a move ends it silently, and the first sign is a taxable value that has doubled.
2024 rebate recipients were enrolled automatically — check anyway
Owners who received the 2024 property tax rebate qualified for 2026 without applying, unless ownership changed, the property stopped being a principal residence, or they claimed the rate on a different property. That covers a lot of Montanans, and it is exactly the group most likely to assume they are fine when a transfer has quietly ended it.
If you were eligible for 2026 and never filed
There is a one-year recovery, and it is homestead-only. MCA 15-6-407 lets an owner who was eligible but “failed to file an application” recover the difference between the taxes paid and the taxes that would have been due, by filing an informal appeal with the department. The deadline is fixed, and it is earlier than most people expect — the mechanics, and who it does not reach, are here.
If a claim is denied
A denial runs on its own appeal ladder — MCA 15-6-418, beginning with an objection to the department within 30 days of the denial notification. It is not the same track as a value appeal, and there is a separate filing at the county board that is very easy to miss and that leaves the board without authority to hear the eligibility question at all. Options at that point include the departmental review, the county tax appeal board, and professional help; the sequence matters more than the argument.

- The long-term rental rate is not 1.1%
Nearly every summary calls Montana's long-term rental reduced rate a flat 1.1%. The statute gives a qualifying rental the same graduated bands as a homestead, starting at 0.76% — and the flat rate applies to multifamily units only.
- Can you still fix 2026?
The 2026 application window closed March 1 — but an owner who was eligible for the homestead rate and never applied can recover one year by informal appeal to the Department of Revenue, by May 31, 2027. There is no long-term-rental equivalent.
- The bands are cumulative, not a lookup
Montana's reduced-rate bands fill in order like tax brackets. Reading them as a lookup — finding your band and applying that rate to the whole house — overstates the taxable value on a larger home by thousands, and sends people into appeals with nothing to argue.
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.
