How Property Tax Works

San Miguel County's property tax system funds essential local services including schools, county operations, fire protection, library services, and various special districts throughout the county. Property taxes are calculated based on assessed values determined by the County Assessor and applied tax rates that vary significantly by location within the county due to multiple overlapping special taxing districts.

The county follows Colorado's standard assessment practices with residential properties assessed at 6.765% of actual value and most commercial properties at 24% of actual value. Effective tax rates typically range from approximately 0.8% to 1.4% of market value, though rates can vary considerably depending on which special districts serve your specific property location. Areas within municipalities like Telluride, Mountain Village, and Norwood, as well as various fire protection and metropolitan districts, will have different total tax rates than unincorporated county areas.

When Are Property Taxes Due?

For the 2025/2026 tax year in San Miguel County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in San Miguel County are additional property tax bills issued when there are changes to property ownership, new construction completion, or significant improvements that increase assessed value mid-tax year. These supplemental assessments pro-rate the additional tax liability from the date of change through the end of the current tax year.

For example, if you complete a $200,000 home addition in July and your property is in an area with a combined tax rate of 12 mills ($12 per $1,000 of assessed value), the supplemental tax would be calculated on the increased assessed value ($200,000 × 6.765% = $13,530 additional assessed value × 0.012 = $162.36) pro-rated for approximately 6 months, resulting in a supplemental bill of about $81. Supplemental tax bills are typically mailed within 30-60 days of the assessor processing the change and become due immediately upon issuance.

Section 5

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts for San Miguel County properties, collecting monthly payments equal to 1/12 of your annual property tax bill plus insurance premiums. Lenders typically maintain a 2-month cushion in escrow accounts and conduct annual analyses to adjust monthly payments based on actual tax bills and account balances.

Property tax payments from escrow accounts are usually made in two installments following the county's payment schedule: the first half by February 28th and the second half by June 15th, though lenders may opt to pay the full amount by the April 30th deadline. Property owners should verify their lender is making timely payments, as the property owner remains ultimately responsible for tax obligations. You can verify payments online through the San Miguel County Treasurer's website or by calling (970) 728-3700.

Q: When are property taxes due in San Miguel County? A: For tax year 2024, you can pay the full amount by April 30, 2025, or make half payments by February 28, 2025 (first half) and June 15, 2025 (second half). Late payments incur interest charges and potential tax lien procedures.

Q: What tax credits are available and how do I apply? A: San Miguel County offers several tax credits that require annual application: Senior Homestead Credit (up to $6,800 for qualifying seniors), Disabled Veteran Credit, and Agricultural Classification. Applications must be filed with the Assessor's office by July 1st for the following tax year. Contact (970) 728-3954 for applications.

Q: How does the Homestead Credit work? A: The Homestead Credit limits annual assessment increases to no more than 10% for qualifying primary residences, regardless of market value changes. This is NOT automatic - you must apply annually by July 1st with the County Assessor. The credit can provide substantial savings in rapidly appreciating markets.

Q: How often are properties reassessed? A: Colorado requires county-wide reappraisals every two years. San Miguel County typically conducts physical inspections and market analysis updates on this schedule, with values effective for the following two tax years.

Q: Can I pay property taxes online? A: Yes, San Miguel County offers online payment options through their website at sanmiguelcountyco.gov. You can pay by electronic check or credit card, though credit card payments include processing fees.

Q: How do special district taxes work? A: Your property may be served by multiple special districts (fire, water, parks, metropolitan districts) each with separate tax rates. These appear as line items on your tax bill and fund specific local services. Special district rates can change based on voter-approved mill levies and bond issues.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed by June 8th (for the current tax year) with the San Miguel County Board of Equalization. You'll need comparable sales data or professional appraisal evidence to support your appeal. Contact the Assessor's office at (970) 728-3954 for appeal forms and procedures.
