Rate Breakdown

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

How Property Tax Works in Gilpin County

Gilpin County determines property taxes by first assessing the market value of each parcel. The County Assessor’s Office conducts an annual physical inspection, reviews recent sales, and applies standardized valuation models to arrive at a “assessed value,” which is typically 100 % of the market value for residential properties. That assessed value is then multiplied by the county’s combined millage rate—expressed as dollars per $1,000 of assessed value—to calculate the annual tax bill. For 2024, Gilpin’s total millage rate (county, school, fire, and special districts) is approximately 48.5 mills, but individual districts may vary, so the exact amount can differ from one address to another.

Available Exemptions

Colorado law provides several exemptions that can lower the taxable portion of your assessed value. Gilpin County applies these state‑wide programs as follows:

• Homestead Exemption: Homeowners qualifying for the Colorado homestead exemption receive a $2,500 reduction in assessed value. The exemption applies automatically once you file a homestead declaration with the county assessor.
• Senior Citizen Exemption: Residents aged 65 or older may qualify for an additional $1,000 reduction if their household income does not exceed the state‑defined limit (typically around $60,000). Proof of age and income must be submitted annually.
• Disability Exemption: Colorado offers a $1,000 exemption for property owners with a qualifying disability. Documentation from a licensed medical professional is required.
• Veteran Exemptions: Disabled veterans receive a $250 reduction per year for every 10% of disability rating, up to a maximum of $2,500. Surviving spouses of veterans who died in service may also be eligible for the full exemption.

All exemptions must be claimed on the Colorado Statewide Property Tax Exemption Application (Form DR 1400) and submitted to the Gilpin County Assessor’s Office before the assessment notice deadline.

Payment Schedule & Deadlines

Gilpin County parcels are taxed on a fiscal year that runs July 1 through June 30. The county offers two primary payment options:

• Annual Lump‑Sum: Pay the full amount by March 31. This option includes a modest 0.5 % discount for early payment.
• Two‑Installment Plan: Pay 50 % by March 31 and the remaining 50 % by July 31. No discount is applied, but the schedule helps spread cash flow.

If either deadline is missed, a 10 % penalty is assessed on the overdue portion, plus interest at the state‑mandated rate (currently 7 % per annum). Continued non‑payment can lead to tax lien issuance, property seizure, or forced sale by the county.

Appealing Your Assessment

If you believe your property has been over‑assessed, Gilpin County provides a clear appeals process:

• Step 1 – Notice of Intent: Submit a written Notice of Intent to Appeal to the Assessor’s Office within 30 days of receiving your assessment notice.
• Step 2 – Formal Appeal: File a Formal Appeal with the Gilpin County Board of Assessment Appeals (BAA) within 60 days of the assessment. Include supporting evidence such as comparable sales, independent appraisals, or photographs.
• Step 3 – Hearing: The BAA will schedule a hearing, typically within 90 days of filing. You may present your case in person or via a qualified representative.
• Step 4 – Decision: The Board issues a written decision within 30 days of the hearing. If the decision is unfavorable, you may further appeal to the Colorado Board of Assessment Appeals within 30 days of the county decision.

Preparing a well‑documented appeal and meeting each deadline greatly improves the likelihood of a successful outcome.
