Rate Breakdown

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

How Property Tax Works in Douglas County

In Douglas County, your property tax bill is calculated by multiplying the County’s assessed value of your land and improvements by the combined millage rates of the taxing entities that serve your address. The assessment process begins with the Douglas County Assessor’s Office, which determines market value each year based on comparable sales, size, age, and condition of the property. Once the market value is established, the assessor applies a uniform assessment ratio—75 % for residential property—to arrive at the taxable value. Millage rates are expressed in “mills,” where one mill equals one‑tenth of one percent ($0.001) of the taxable value. In 2024, the total combined rate for most residential parcels is roughly 8.5 mills (≈ $85 per $10,000 of assessed value), but rates vary depending on school districts, fire protection, and special districts that overlap your parcel.

Available Exemptions

Colorado offers several exemptions that can reduce the taxable portion of your property. Douglas County applies these exemptions automatically when you qualify, but you must submit the appropriate application forms to the Assessor’s Office.

• Homestead Exemption: Reduces the taxable value of your primary residence by $200,000 (or $120,000 for properties built before 1975). The exemption applies automatically if the property is your legal residence.
• Senior Citizen Exemption: Residents aged 65 or older may receive an additional $35,000 reduction in taxable value, provided they meet income thresholds (generally $30,000 household income).
• Disability Exemption: Qualified disabled persons can claim a $10,000 exemption (or $20,000 for qualifying children). Proof of disability from a licensed physician is required.
• Veteran Exemption: Eligible veterans, especially those with service‑connected disabilities, may receive a $1,200 exemption per qualifying veteran residing in the home. Surviving spouses of veterans killed in action are also eligible.

Payment Schedule & Deadlines

Douglas County collects property taxes in two installments. Paying on time can save you from interest and penalties.

• First installment: Due on March 5 each year. The amount is 50 % of the estimated tax bill, calculated from the previous year’s assessment.
• Second installment: Due on August 5. This payment covers the remaining balance and any adjustments due to reassessments.
• Late payment consequences: If a payment is not received by the due date, a 5 % penalty is added to the overdue amount, plus a 0.5 % per month interest charge.
• Installment options: The County offers electronic payments through the Douglas County Treasurer’s online portal, as well as mailed checks and in‑person payments at the Treasurer’s office. Automatic recurring payments can be set up to avoid missed deadlines.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, Douglas County provides a formal appeals process.
