Silver Bow Property Tax Rates and Classifications
Silver Bow Property Tax rates are set every year by the Montana Department of Revenue using a tiered system based on property class. Residential homes, commercial buildings, agricultural land, and industrial sites all carry their own mill levy.
For tax year 2026, the average effective rate across Silver Bow County sits near 0.73 percent of taxable value, well below many larger Montana counties. Residential primary residences and long-term rentals now use lower tiered rates that took effect after the 2026 property tax overhaul.
The Montana Department of Revenue publishes a quick comparison of property tax rates by class for 2026, 2026, and 2026 at https://revenuefiles.mt.gov/property/property-tax-changes/compare-rates. This comparison helps owners see how the shift in rates will affect their annual bill.
| Property Class | Typical Use | 2026 Effective Rate |
|---|---|---|
| Class 3 | Agricultural land | Lower tier rate set by DOR |
| Class 4 Primary Residence | Owner-occupied home | Tiered rate based on value |
| Class 4 Long-term Rental | Rental with 30+ day stays | Tiered rate based on value |
| Class 4 Non-primary | Second home or vacation rental | Higher rate under 2026 rules |
| Class 7 | Commercial real property | Set by DOR formula |
| Class 9 | Industrial property | Set by DOR formula |
The tax bill you receive each November reflects these class-based rates combined with local mill levies approved by voters. Levies from Butte-Silver Bow schools, the county, and the city all stack onto the base state rate.
How Silver Bow County Property Assessments Work
Silver Bow Property Tax assessments follow a two-step process set by Montana law. The Montana Department of Revenue values the property based on class, while the county assessor maintains the parcel record and mailing address.
Property owners receive an appraisal notice each year showing the department’s classification, market value, and taxable value. The notice explains how to read each number, what the deadline for review is, and which office can answer questions about the data.
If you need to check the records held at the county level, the iTax portal lets you pull the parcel card. The card shows lot size, year built, improvement details, and the legal description used on the deed.
- The Montana Department of Revenue values the property using sales and income data.
- The county assessor keeps the parcel map, owner address, and exemption status current.
- Market value reflects what the home would sell for in an open market.
- Taxable value is the figure the mill levy is applied to after exemptions.
- Owners get a notice every spring with the new values before bills go out.
Reading Your Silver Bow Property Tax Bill
Silver Bow Property Tax bills arrive by mail in late October or early November each year. The bill lists two installments with separate due dates and shows every taxing district that receives a share of the payment.
Each section of the bill carries a specific code. The first line shows the countywide mill levy, the next line shows the city of Butte levy, and additional lines cover school districts, the college district, and any special districts like street or lighting funds.
Owners can see the full bill online through the iTax portal at https://itax.tylertech.com/ButteSilverBowMT/. The portal also shows a two-year mill levy comparison by parcel so you can track year-over-year changes at a glance.
| Line on Bill | What It Means |
|---|---|
| Taxable Value | Number the mill levy is applied to |
| Mill Levy | Total mills from all taxing districts |
| Base Tax | Taxable value times mill levy divided by 1,000 |
| Special Assessments | Street, lighting, or sidewalk fees |
| Total Due | Sum of base tax, assessments, and fees |
| Delinquent Date | Day late fees begin to accrue |
The bill also shows a barcode that scanners use at payment counters. Keep the bottom stub when you pay by mail and write the taxpayer ID on the check so the payment posts to the right parcel.

Property Tax Exemptions in Silver Bow County
Silver Bow Property Tax exemptions can lower the bill for qualifying owners. The Montana Department of Revenue runs several statewide programs that Silver Bow County residents can apply for through the state forms repository.
Common exemptions include the homestead exemption for primary residences, the disabled veteran exemption, and the elderly homeowner credit. Long-term rental owners may also qualify for the lower tier rate under the 2026 tax law changes.
Forms for these programs are posted on the Montana Department of Revenue forms page found at http://revenue.mt.gov/forms/. Each form lists the documents you must send with the application and the deadline for filing.
| Program | Who Qualifies | Benefit |
|---|---|---|
| Homestead Exemption | Owner-occupied primary residence | Reduces taxable value on class 4 homes |
| Disabled Veteran Exemption | Veterans with service-connected disability rating | Partial or full reduction based on rating |
| Elderly Homeowner Credit | Homeowners age 62 and older with limited income | Direct credit applied to the tax bill |
| Long-term Rental Rate | Rentals with 30+ day average stays | Lower tiered state rate under 2026 rules |
| Intensive Agricultural Use | Land producing at set yield levels | Lower class rate on qualifying parcels |
Most exemption applications must be filed with the Montana Department of Revenue rather than the county. After approval, the lower taxable value flows into the county tax roll and shows up on the next bill.
Silver Bow Property Tax Appeal Process
Silver Bow Property Tax appeals give owners a way to challenge the value, class, or both shown on the appraisal notice. The Montana Department of Revenue runs the informal review first, and the County Tax Appeal Board hears formal appeals when the two sides still disagree.
The informal review window opens when the appraisal notice is mailed and closes on the date printed on the notice. Formal appeals to the County Tax Appeal Board must be filed within 30 days of the notice date for most property classes.
Detailed steps for filing both the informal review and the formal appeal are posted at https://revenue.mt.gov/property/appraisal/appeals-and-reviews. The page explains the evidence you should gather, the hearing format, and the time limit for adjustments.
- Read the appraisal notice and note the class, market value, and taxable value.
- Pull recent sale prices of similar homes in the same neighborhood.
- Submit a written request for an informal review before the deadline.
- If the review is denied or the offer is too low, file a formal appeal with the County Tax Appeal Board.
- Bring photos, sales data, and repair estimates to the appeal hearing.
Homeowners who miss the informal deadline can still file a late appeal until June 1, 2026, but late appeals only apply to the 2026 tax year. Acting inside the standard window gives you the best chance of a value change for the current year.
Delinquent Taxes and Tax Lien Sales in Silver Bow
Silver Bow Property Tax bills that go unpaid move into the delinquent column and start to accrue interest and fees. The county publishes a list of delinquent parcels each year and runs a tax deed auction to recover the unpaid amounts.
Delinquent mobile home taxes for 2026 are tracked on a dedicated page on the county website. The page explains the late fees, the redemption period, and the auction date for any mobile home parcel that remains unpaid.
Information about the tax deed auction, the delinquent tax process, and the list of parcels headed for auction is found at https://www.co.silverbow.mt.us/2185/36502. The page is updated each year before the auction begins.
- Interest accrues monthly on any unpaid tax balance.
- A penalty fee is added once the bill reaches the delinquent date.
- Tax lien certificates can be sold to investors to help the county recover funds.
- Owners have a redemption period to pay the full balance plus fees.
- Unredeemed parcels are sold at the annual tax deed auction.
Paying a delinquent tax before the redemption deadline ends the process and removes the parcel from the auction list. Owners who cannot pay in full can contact the Treasurer to set up a payment plan when one is available.

Deadlines for the current cycle are posted on the 2026 tax information page at https://revenue.mt.gov/property/property-tax-changes/2026-property-tax-information. The page lists the tiered rate structure, the declaration form, and the penalty for missing the March 1 cut-off.
