How Property Tax Works

Phillips County, Colorado operates on a property tax system that serves as the primary funding source for essential local services including education, road maintenance, public safety, and county operations. Property taxes in Phillips County are collected annually and fund various special districts throughout the county, meaning your actual tax rate will depend on your specific location within the county and which special taxing districts serve your property.

The county assesses residential properties using Colorado's dual assessment rate system, with different rates applied for school and non-school purposes. Phillips County has approximately 355 property owners currently benefiting from senior citizen and disabled veteran homestead exemptions. Property owners should note that most tax credits and exemptions require annual application and are not automatically applied to your assessment.

Effective property tax rates in Phillips County typically range from 0.8% to 1.2% of market value, depending on your location and applicable special district levies. The county also receives supplemental funding through State Highway Users Tax monies and FASTER funds to support road and bridge infrastructure.

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 Phillips County are triggered by changes in property ownership, new construction, or significant improvements that increase a property's assessed value during the tax year. When these events occur after the annual assessment date but before the tax year ends, a supplemental assessment is calculated based on the increased value for the remaining portion of the tax year.

The supplemental tax is calculated by determining the difference between the new assessed value and the original assessed value, then applying the current tax rate to this difference, prorated for the number of months remaining in the tax year. For example, if you complete a $50,000 home addition in July, and your total mill levy is 25 mills, the supplemental tax would be calculated on the increased assessed value ($50,000 × 6.25% = $3,125) × 25 mills × 6 months remaining = approximately $468 in additional taxes for that year.

Supplemental tax bills are typically issued within 60-90 days of the triggering event and become due immediately upon issuance. These taxes are separate from your regular annual property tax bill and must be paid to avoid delinquency fees.

Escrow & Property Taxes

Most mortgage lenders in Phillips County require borrowers to maintain an escrow account for property tax payments, particularly for loans with less than 20% down payment. Your lender will collect monthly escrow payments equal to 1/12th of your estimated annual property tax bill, plus a small cushion as allowed by federal law.

Property tax payments from escrow accounts are typically made directly by your lender to Phillips County before the January 31 due date. Lenders usually pay in late December or early January to ensure timely payment. Your lender will provide an annual escrow analysis showing how your payments were applied and any adjustments needed for the coming year.

If your property taxes increase due to reassessment or rising mill levies, your lender may require you to make up any escrow shortage over 12 months while simultaneously increasing your monthly payment. You can verify your property tax payments by checking with the Phillips County Treasurer's Office or reviewing your annual mortgage statement. Property owners remain ultimately responsible for ensuring taxes are paid even when using escrow services.

Frequently Asked Questions

Q: When are property taxes due in Phillips County? A: Property taxes are due by January 31 each year for the current tax year. If you don't receive your tax statement by January 31, contact the Treasurer's Office immediately. Taxes become delinquent on June 16 with additional fees and interest applied.

Q: What tax credits are available and how do I apply? A: Phillips County offers senior citizen and disabled veteran homestead credits. Both require annual application through the Assessor's Office. The senior homestead credit is available to qualifying residents age 65+ and limits assessment increases. Applications must be filed by the deadline specified by the Assessor's Office.

Q: How does the homestead credit work? A: The homestead credit caps annual assessment increases rather than reducing market value. It limits how much your assessed value can increase each year, providing tax relief as property values rise. You must apply annually and meet income and residency requirements.

Q: How often are properties reassessed? A: Colorado law requires properties to be reassessed every two years. Phillips County follows the state schedule for revaluation. Property owners receive notice of assessment changes and have the right to appeal through the county Board of Equalization.

Q: Can I pay my property taxes online? A: Contact the Phillips County Treasurer's Office directly for current online payment options and accepted payment methods. Payment policies may vary and change periodically.

Properties in different areas of Phillips County may have significantly different total tax rates based on their district combinations.

Q: What if I disagree with my property assessment? A: You have the right to appeal your assessment to the Phillips County Board of Equalization.
