Treasure County Tax Parcel Mapping and Valuation Methodology

Tax parcel mapping data in Treasure County is maintained by the Assessor office using the county’s cadastral system. Parcels are linked to ownership records filed with the Clerk and Recorder, and each parcel carries a unique geocode used in valuation calculations. The taxable property definition applied by the Montana Department of Revenue includes land, improvements, structures, and certain mobile homes classified as real property.

• Residential parcels include single-family homes, townhomes, and condominiums.

Property taxes are paid in arrears under Montana’s two-installment payment system, and full payment is also an option. Half payments are accepted under the state’s two-installment payment system.

• Second installment due date: Refer to the official county website for the current year’s tax calendar.
• Delinquency date: Refer to the official county website for the current year’s tax calendar.

For specific due dates, penalty rates, and payment plan terms, owners should contact the Treasurer’s office directly or visit the county website at https://www.treasurecountymt.gov for the current year’s tax calendar.

Treasure County Property Tax Assessment Appeal Process

Treasure County Property Tax assessment appeal follows a two-step process governed by Montana law. The first step is an informal review with the Montana Department of Revenue, which handles valuation and classification for most property types. The second step is a formal appeal to the Treasure County Tax Appeal Board (CTAB), an independent panel that reviews disputed assessments.

1. Property owner receives the notice of assessment from the Department of Revenue.
2. Owner files a written protest with the county treasurer and pays the disputed tax under protest by the payment due date, as required under 15-1-402, MCA.
3. Owner requests an informal review with the Department of Revenue within 30 days of the notice.
4. If unsatisfied with the informal review decision, owner appeals to the CTAB within 30 days of the decision.
5. CTAB holds a hearing and issues a determination.
6. Further appeals may be filed with the Montana State Tax Appeal Board or district court.

Detailed filing instructions and the CTAB appeal form are available at https://hometaxappeal.us/mt/treasure/. The Montana Property Tax Appeal Form (CTAB form) can be completed online and submitted to the Treasure County Clerk and Recorder’s office. Owners appealing their assessment must continue paying the disputed tax under protest during the appeal process, with refunds issued if the appeal succeeds.

Paying taxes under protest activates the property tax refund process if the appeal results in a reduced valuation. Montana law requires the county treasurer to hold protested funds in escrow until the appeal concludes, after which refunds are issued for any overpayment plus statutory interest.

Treasure County Property Tax Protest Forms and Filing Steps

Property tax protest forms in Treasure County are standardized under Montana’s CTAB system. Property owners can obtain the official CTAB appeal form through the Montana Department of Revenue, the Treasure County Clerk and Recorder, or the online fillable version at https://www.pdffiller.com/45556539-CTAB_TaxAppealForm09pdf-Montana-Property-Tax-Appeal-Form-. The form requires parcel identification, owner’s contact details, the disputed assessed value, the owner’s opinion of value, and supporting evidence such as comparable sales, appraisal reports, or income documentation.

File the completed protest form with the Treasure County Clerk and Recorder at the county courthouse in Hysham, MT. The Clerk and Recorder’s office accepts protests on behalf of the CTAB and forwards them to the appropriate review body. Property owners filing a protest must also submit a written protest to the county treasurer and pay the disputed tax under protest, as detailed at https://revenue.mt.gov/property/appraisal/appeals-and-reviews.

Appeals filed after the 30-day deadline risk dismissal, so property owners should respond promptly upon receiving the assessment notice. CTAB hearings are open to the public and conducted in Hysham at the county courthouse, with scheduling coordinated through the Clerk and Recorder’s office.

Treasure County Property Tax Lien Auction Schedule

Treasure County Property Tax lien auctions are conducted by the county for properties with delinquent taxes that remain unpaid after the delinquency date. The lien auction process follows Montana’s tax sale procedures, with the county publishing a list of delinquent properties in a local newspaper and on the county website before the sale date. The property tax lien auction schedule for Treasure County is set by the county commissioners and published in advance.

Properties not sold at the initial lien auction may be struck off to the county, which then holds the tax lien until the property is redeemed, sold, or foreclosed. Redemption periods and interest rates on tax liens are set by Montana statute, with redemption typically allowed for a set number of years after the tax sale. Owners facing a tax lien auction can prevent the sale by paying all delinquent taxes, penalties, and interest before the auction date.

For current auction schedules, delinquent property lists, and redemption procedures, contact the Treasure County Clerk and Recorder through the county website. Information about tax sale procedures is also available through the county website at https://www.treasurecountymt.gov.

Treasure County Property Tax Delinquency Penalties

Property tax delinquency penalties in Treasure County follow Montana’s statutory framework, which includes interest accrual on unpaid balances and potential lien placement. After the second installment due date passes, unpaid taxes become delinquent, and interest begins accruing at the rate set by the Montana Department of Revenue. The interest rate is adjusted periodically and applies to both the tax amount and any accumulated penalties.

• Late payment interest accrues monthly on the unpaid balance.
• Penalty fees apply as a percentage of the delinquent tax amount.
• Property lien filing occurs after the statutory redemption period expires.
• Court costs and attorney fees may be added if the county pursues foreclosure.

Property owners who cannot pay their full tax obligation should contact the Treasurer’s office before the delinquency date to request a payment plan. Property tax payment plans typically allow the owner to pay delinquent taxes in monthly installments over a set period, with interest continuing to accrue on the unpaid balance. Owners receiving a notice of delinquency should respond promptly to avoid lien placement and additional collection costs.

For the current delinquency penalty rate, interest rate, and payment plan eligibility requirements, contact the Treasure County Treasurer’s office or visit the Montana Department of Revenue website at https://revenue.mt.gov/property/appraisal/appeals-and-reviews.

Treasure County Property Tax Refund Process

The property tax refund process in Treasure County applies to owners who overpaid their taxes, paid under protest and won an appeal, or qualify for a retroactive exemption. Refunds are issued by the Treasure County Treasurer’s office after a refund claim is approved. The refund amount includes the overpaid tax plus statutory interest accrued from the original payment date.

Owners who paid taxes under protest and received a favorable CTAB decision are entitled to a refund of the protested amount exceeding the corrected tax liability. The Treasure County Treasurer processes these refunds after receiving the CTAB determination and the owner’s refund request. Refund claims for overpayment due to clerical error or duplicate payment are filed directly with the Treasurer’s office.

To initiate a refund request, contact the Treasure County Treasurer’s office at the phone number listed on the county website, or visit the office in person at the county courthouse in Hysham, MT. Required documentation includes proof of overpayment, the CTAB decision (if applicable), and a completed refund claim form.

Treasure County Property Tax Abatement Criteria

Property tax abatement criteria in Treasure County allow owners to seek reduction or elimination of taxes under specific circumstances defined by Montana law. Abatement may be granted for properties affected by natural disaster, demolition, fire damage, or other qualifying conditions that reduce the property’s value. The application is filed with the Montana Department of Revenue, which reviews the request and forwards a recommendation to the county commissioners for final approval.

• Fire or natural disaster damage reducing the property’s value.
• Demolition of a structure leaving only land value.
• Change in property use or classification affecting taxable value.
• Error in valuation or classification by the assessor.

Property tax abatement applications require supporting documentation, including photographs, repair estimates, contractor invoices, or appraisal reports verifying the reduced value. The Treasure County Commissioners hold a public hearing on each abatement request and issue a decision within the statutory timeframe. Approved abatements result in a tax reduction for the affected tax year only, and owners must reapply for subsequent years if conditions persist.

For abatement forms, filing instructions, and statutory criteria, contact the Montana Department of Revenue or the Treasure County Clerk and Recorder through the county website.

Treasure County Property Tax Audit Procedures

Property tax audit procedures in Treasure County apply to commercial, industrial, and income-producing properties where reported income, expenses, or operating data must be verified. The Montana Department of Revenue periodically conducts property tax audits to confirm that reported rental income, expense ratios, and occupancy rates align with the income approach used in the property’s valuation. Property owners selected for audit receive a written notice identifying the records required and the audit timeline.

Owners selected for a property tax audit must provide income and expense statements, rent rolls, lease agreements, and operating data covering the relevant audit period. The Department of Revenue compares the reported data against industry benchmarks and may adjust the property’s valuation if discrepancies are found. Audit results can be appealed through the same CTAB process used for regular assessment appeals.

Property owners facing a property tax audit should gather documentation early and consider engaging a certified appraiser or tax professional to represent them. Detailed records of income, expenses, and capital improvements strengthen the owner’s position during the audit review. Contact the Montana Department of Revenue for current audit selection criteria and procedures.

Treasure County Property Tax Calculator and Estimation Methods

Property owners estimating their Treasure County Property Tax liability can use the statewide calculator at https://statecalc.com/property-tax/montana-property-tax-calculator/, which applies Montana’s effective rate of 0.84% to estimate annual taxes. The calculator factors in the homestead exemption of up to $250,000 for owner-occupied primary residences and the 2026 tiered rate structure for higher-value properties.

Property owners can also request a written estimate from the Assessor office through the county website.

The Montana Property Tax records and lookup resources at https://propertytaxusa.org/montana-property-tax/ provide county-level data, payment instructions, and answers to frequently asked questions about property tax estimation and billing.

Treasure County Residential Property Tax Rebates and Senior Credits

Residential property tax rebates in Treasure County may be available through Montana’s Residential Property Tax Credit for Seniors and the Disabled, also known as the Elderly Homeowner Credit. This refundable income tax credit reimburses a portion of property taxes paid by qualifying Montana residents who meet age and income requirements set by the state. The credit is claimed on the owner’s Montana state income tax return, not on the property tax bill.

• Age requirement: Refer to the Montana Department of Revenue for current criteria.
• Income limit: set annually by the Montana Department of Revenue.
• Maximum credit: based on property taxes paid and income level.
• Application: filed with the Montana state income tax return.

Property tax credit for seniors and disabled residents is separate from the senior property tax exemption applied at the county level. The exemption reduces the property’s taxable value, while the credit provides a direct refund based on income and property taxes paid. Property owners may qualify for both programs if they meet the respective eligibility criteria.

For current income limits, credit maximums, and application procedures, visit the Montana Department of Revenue website or consult a tax professional familiar with Montana property tax programs.

Treasure County Commercial Property Tax Surcharge and Special Assessments

Commercial property tax in Treasure County follows the same valuation methodology as residential property but faces higher effective rates under Montana’s 2026 tiered system. Commercial property classified as a long-term rental qualifies for the reduced tier-one rate, while short-term rentals, second homes, and investment properties fall into higher tiers. Property owners should verify their property’s classification with the Montana Department of Revenue, as classification errors can result in significant overpayment.

Special assessment charges apply to properties located within special improvement districts, tax increment financing districts, or other designated areas. These charges fund local infrastructure improvements such as roads, sidewalks, water lines, and sewer systems. Special assessment charges are billed separately from the regular property tax bill and are typically collected by the county or the local improvement district.

Tax increment financing districts in Treasure County capture a portion of property tax revenue from the district’s assessed value growth to fund public improvements. Property owners in a TIF district pay the same property tax rate, but the incremental revenue above the district’s base value is directed to the TIF fund rather than the general taxing jurisdictions. The Treasure County Commissioners oversee TIF district establishment and reporting requirements.

Treasure County Historic Preservation Tax Relief and TIF Districts

Historic preservation tax relief in Treasure County is available for properties listed on the National Register of Historic Places or designated as local historic landmarks. Montana offers a property tax freeze for qualifying historic residential properties, allowing owners to maintain their assessed value at the pre-rehabilitation level for up to five years following qualified rehabilitation work. Commercial historic properties may qualify for additional incentives through the federal historic rehabilitation tax credit.

• Property must be listed on the National Register of Historic Places.
• Rehabilitation work must meet the Secretary of the Interior’s Standards.
• Minimum investment threshold: 25% of the property’s assessed value.
• Application: filed with the Montana Department of Revenue before work begins.

Real estate tax incentive programs in Treasure County also include the Montana Affordable Housing Tax Credit, which provides incentives for developers of qualifying low-income housing projects. Developers can apply for the credit through the Montana Board of Housing, and the credit can be combined with federal Low-Income Housing Tax Credits to support affordable housing development in the county.

Property owners interested in historic preservation tax relief or affordable housing incentives should contact the Montana Department of Revenue, the Montana State Historic Preservation Office, or the Treasure County Assessor through the county website for guidance on program eligibility and application procedures.

Treasure County Municipal Tax Revenue Trends and Property Tax Burden

Municipal tax revenue trends in Treasure County reflect the county’s rural character and limited population base. Property tax revenue is the primary funding source for county services, schools, and special districts, with the county’s annual property tax levy published on the Montana Department of Revenue’s Annual Property Tax Changes page at http://revenue.mt.gov/propertytaxchanges/. Treasure County’s tax base is dominated by agricultural land, residential properties, and a small number of commercial holdings, making the property tax burden analysis sensitive to changes in agricultural commodity prices and assessed valuations.

Property tax burden analysis for Treasure County residents shows a moderate burden compared to the Montana statewide average, with the county’s effective rate of 0.71% sitting below the statewide 0.84% effective rate. Homeowners in Hysham face a higher effective rate of 1.01% due to overlapping municipal, school, and county levies. Property tax revenue per capita in Treasure County tracks with rural Montana counties and supports essential services including road maintenance, emergency services, and K-12 education.

Statewide comparison data from the Tax Foundation at https://taxfoundation.org/data/all/state/property-taxes-by-state-county/ ranks Montana’s effective property tax rate in the lower half of all U.S. states, with Treasure County positioned below the state median. The 2026 tiered rate changes aim to shift more of the property tax burden onto higher-value and non-primary-residence properties while providing relief for owner-occupied homes.

Treasure County State Property Tax Cap Legislation

State property tax cap legislation in Montana limits the annual growth of property tax revenue for certain taxing jurisdictions. Under current Montana law, local government entities and school districts face limits on the amount of property tax revenue they can raise from existing properties each year, though voter-approved levies and new construction are exempt from the cap. The cap formula accounts for inflation, population growth, and other factors, with the final calculation performed by the Montana Department of Revenue.

Treasure County taxing jurisdictions, including the county, school districts, and special districts, must comply with the state’s property tax cap when setting annual budgets. The Montana Department of Revenue certifies mill levies each year and notifies jurisdictions of any required reductions to stay within the cap. Property tax revenue per capita figures and cap compliance data are published annually at http://revenue.mt.gov/propertytaxchanges/.

The 2026 tiered rate structure introduced by the Montana Legislature works in conjunction with the state’s property tax cap provisions. Primary residences and long-term rentals receive the most favorable treatment under the new system, while second homes, short-term rentals, and high-value properties contribute a larger share of the overall tax burden.

Treasure County Property Tax Payment Plans and Real Estate Tax Incentive Programs

Property tax payment plans in Treasure County allow owners facing financial hardship to pay delinquent taxes over time rather than facing immediate lien or foreclosure action. The Treasure County Treasurer evaluates payment plan requests on a case-by-case basis, considering the owner’s financial situation, the amount of delinquency, and the likelihood of collection. Approved plans typically require monthly payments, accrual of interest on the unpaid balance, and timely payment of current-year taxes as a condition of the agreement.

Real estate tax incentive programs available in Treasure County include the Montana property tax abatement for damaged property, the historic preservation tax freeze, the senior and disabled property tax credit, and the long-term rental reduced rate. Developers of affordable housing can access state and federal tax credits through the Montana Board of Housing, and agricultural property owners benefit from the state’s productivity-based valuation system for qualified farmland.

Property owners exploring available incentive programs should contact the Treasure County Assessor through the county website for information on exemptions and reduced rates, the Montana Department of Revenue at https://revenue.mt.gov/property/property-tax-changes/enroll for the 2027 reduced rate enrollment, and the Montana Board of Housing for affordable housing incentives.
