How Property Tax Works

Eagle County's property tax system funds essential local services including schools, fire protection, libraries, and county operations. The county uses an assessment-based system where properties are valued by the County Assessor, then taxed at rates set by various local government entities. For the 2025 tax year, residential properties are assessed at 6.25% of their actual (market) value for local government mill levies, with a separate assessment rate applying to school district levies.

Your actual property tax rate depends on your specific location within Eagle County, as you may be subject to additional taxes from special districts such as fire districts, library districts, water districts, or metropolitan districts. The total effective tax rate typically ranges from approximately 0.4% to 0.8% of market value, though this can vary significantly based on the special taxing districts that serve your property. Property taxes are collected by the County Treasurer and distributed to the various taxing entities that provide services to your area.

Supplemental Tax Bills

Supplemental taxes in Eagle County are additional property tax bills issued when there are mid-year changes to your property's assessed value. The most common triggers include new construction completion, property improvements with permits, ownership changes that remove certain exemptions, or corrections to the original assessment. Unlike the regular tax bill, supplemental taxes are prorated based on the number of months remaining in the current tax year when the change becomes effective.

For example, if you complete a $100,000 home addition in September and it's added to the tax roll in October, you would receive a supplemental tax bill covering October through December (3 months) of that tax year. The supplemental tax would be calculated on the additional assessed value ($100,000 × 6.25% = $6,250) multiplied by your area's total mill levy rate, then prorated for the remaining months. If your total mill levy is 40 mills, the annual tax on the addition would be $250, and your supplemental bill would be $62.50 (3/12 × $250).

Section 5

Escrow & Property Taxes

Most mortgage lenders in Eagle County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects 1/12 of your estimated annual property tax bill with each monthly mortgage payment, holding these funds in an escrow account. The lender then pays your property tax bills directly to Eagle County when they become due on March 2nd and June 15th.

Lenders typically maintain a cushion of 2-3 months of tax payments in your escrow account as required by federal regulations. Each year, your lender will conduct an escrow analysis to compare the actual tax bills paid against the amount collected. If taxes increased, you may face a shortage requiring higher monthly payments or a lump-sum payment. If you paid too much, you'll receive a refund or credit toward future payments. You have the right to review your escrow account annually and request explanations of any changes to your monthly escrow amount.

Frequently Asked Questions

Q: When are property taxes due in Eagle County for the current fiscal year? A: Property taxes are due in two equal installments: March 2nd and June 15th. You can pay the full amount by April 30th if you prefer. Taxes become delinquent if not paid by June 15th for the first half or July 31st for the second half.

Q: What tax credits are available and do I need to apply? A: The main credit is the Senior Homestead Credit, which reduces taxes on 50% of the first $200,000 of actual value for qualifying seniors. This credit requires annual application by July 1st. Disabled veteran credits may also be available. Contact the Eagle County Assessor at (970) 328-8610 for applications and eligibility requirements.

Q: How does the Homestead Credit work? A: The Senior Homestead Credit doesn't reduce your home's market value but instead provides a tax credit that reduces your actual tax bill. It applies to 50% of the first $200,000 of your home's actual value, subject to available state funding. You must apply annually by July 1st.

Q: When are properties reassessed in Eagle County? A: Colorado law requires properties to be valued annually, with Eagle County conducting assessments each year. Assessment notices are typically mailed in early May, and you have 30 days from the notice date to appeal if you disagree with the valuation.

Q: What are the penalties for late property tax payments? A: Interest begins accruing at 1% per month on any unpaid balance after the due dates. Properties with taxes delinquent for three years may be subject to tax lien sale proceedings.

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

Q: Why did my tax bill increase if I haven't made improvements? A: Tax increases can result from rising property values, increased mill levies approved by voters, or new special district taxes. Even without improvements, your home's assessed value may increase due to market conditions.

Q: What special districts might affect my property taxes? A: Common special districts in Eagle County include fire protection districts, library districts, water and sanitation districts, and metropolitan districts. Each has separate mill levies that appear on your tax bill. Contact the Eagle County Assessor to determine which districts serve your specific property.
