Rate Breakdown

Property taxes in Mineral County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Mineral County

Every year the Mineral County Assessor’s Office determines the taxable value of each parcel of real‑estate within the county. The process begins with a market‑value assessment, which reflects what the property would likely sell for on the open market as of January 1st of the tax year. This value is then multiplied by the appropriate assessment ratio (usually 100 % for residential property in Colorado) to arrive at the assessed value.

The county applies a series of millage rates—one mill is equal to $1 of tax per $1,000 of assessed value. Mineral County’s total mill rate is the sum of:

• Mineral County General Fund (approximately 23 mills)
• School District 2 (approximately 115 mills)
• Special districts (fire protection, water & sewer, and road improvement, averaging 12‑15 mills)
• Any voter‑approved bonds or levies (varies yearly)

To calculate the annual tax bill, multiply the assessed value by the combined mill rate, then divide by 1,000. For example, a home assessed at $150,000 with a total mill rate of 150 mills would owe ($150,000 × 150) ÷ 1,000 = $22,500 in property taxes before exemptions.

Available Exemptions

Colorado law provides several exemptions that can lower the taxable portion of a property’s assessed value. In Mineral County, eligible owners may claim one or more of the following:

• Homestead exemption – Reduces the taxable value by up to $200,000 for primary residences, effectively eliminating tax on that portion.
• Senior citizen exemption – Residents aged 65 or older may receive an additional $50,000 reduction, subject to income limits set by the state.
• Disability exemption – Qualifying individuals with a physical or mental disability can claim a $75,000 reduction, also subject to income qualifications.
• Veteran exemption – Veterans (or surviving spouses) who served on active duty and have a service‑connected disability may obtain up to $100,000 of exempted value, with larger amounts available for those who are totally disabled.

Exemptions must be applied for on the annual “Property Tax Forms” packet or electronically through the Colorado Revenue Service portal. Once approved, the exemption remains in effect until the property is sold or the owner’s circumstances change.

Payment Schedule & Deadlines

Mineral County property taxes are due in two installments:

• First installment – 10 % of the total bill is due by March 15.
• Second installment – The remaining 90 % is due by October 15.

Property owners may also elect to pay the full amount in a single payment before March 15 to avoid the small administrative surcharge that applies to split payments. Late payments incur a 5 % penalty plus interest calculated at the legal rate, and the county may issue a tax lien if balances remain unpaid after the deadline.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, you have the right to appeal. Follow these steps:

• File a written appeal with the Mineral County Assessor’s Office no later than the Monday following the mailing of the assessment notice (typically early May).
• Include supporting evidence such as recent comparable sales, a professional appraisal, or errors in property data.
• The assessor will schedule a hearing; you may attend in person or, if approved, by telephone.
• After the hearing, the assessor issues a written decision. If the outcome is unsatisfactory, you can appeal to the Colorado Board of Assessment Appeals within 30 days of the decision.

Timely filing and thorough documentation are key to a successful appeal. The county provides a “Guide to Property Tax Appeals” booklet that can be requested online or at the Assessor’s Office.
