Rate Breakdown

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

How Property Tax Works in Dolores County

Dolores County assesses the taxable value of each parcel of real property once a year, usually in the spring. The assessor determines market value by comparing the property to recent sales of similar properties, considering factors such as location, size, improvements, and condition. After the market value is established, the county applies an assessment rate of 7.15 % (the state‑mandated rate for residential property) to arrive at the assessed value that will be used for tax calculations.

Once the assessed value is fixed, the total tax bill is calculated by multiplying that value by the combined millage rate. Millage rates are expressed in “mills,” where one mill equals $1 of tax per $1,000 of assessed value. In Dolores County, the millage rate varies each fiscal year based on the funding needs of the County, School Districts, Water Districts, and special districts such as fire protection or senior services. For example, the 2025‑26 fiscal year showed a combined rate of roughly 56 mills (≈ 5.6 %). To estimate your annual tax, multiply your assessed value by the millage rate and divide by 1,000.

Available Exemptions

Colorado law provides several exemptions that reduce the taxable portion of a property’s assessed value. In Dolores County you may qualify for one or more of the following:

• Homestead Exemption: Reduces the taxable value of a primary residence by $75,000 (as of 2024) for owners who occupy the property as their main home.
• Senior Citizen Exemption: Residents 65 years or older may receive an additional $100,000 exemption on the homestead portion, provided they meet income limits set by the state.
• Disability Exemption: Qualified persons with a permanent disability can claim an extra $75,000 exemption on the homestead portion, subject to verification by the Colorado Department of Revenue.
• Veteran Exemption: Colorado veterans with a service‑connected disability of 60 % or greater are eligible for a $85,000 exemption on their homestead value. Surviving spouses of deceased veterans may also qualify.

All exemptions are applied before the millage rate is calculated, so they directly lower the amount of tax you owe. Applications are submitted to the Dolores County Assessor’s Office, usually by the October deadline for the upcoming tax year.

Payment Schedule & Deadlines

Dolores County issues property tax bills in two installments:

• First Installment: Due on October 1. A discount of 4 % is offered if paid by October 15.
• Second Installment: Due on December 31. No discount is available, but the bill remains payable through the end of the year.

If you miss either deadline, a late fee of 5 % of the unpaid amount is added, and interest accrues at 12 % annually on the delinquent balance. Continued non‑payment can result in a tax lien and, eventually, a tax sale of the property. To avoid penalties, many residents set up automatic bank drafts or pay online through the county’s secure portal.

Appealing Your Assessment

If you believe your property’s assessed value is too high, you have the right to appeal:

• File a Notice of Appeal: Submit the form to the Dolores County Assessor’s Office within 30 days of the date the Assessment Notice is mailed.
• Gather Evidence: Prepare comparable sales, recent appraisals, or photographs that support a lower market value.
• Informal Review: Request a meeting with the assessor for an informal discussion. This often resolves the issue without a formal hearing.
• Formal Hearing: If the informal review does not result in a satisfactory adjustment, your case will be heard by the County Board of Assessors. You may present evidence and testimony.
• Further Appeal: If the Board’s decision is still unsatisfactory, you may appeal to the Colorado Board of Assessment Appeals within 30 days of the Board’s final decision.

Keep all correspondence and documentation, as the appeal process relies heavily on timely and accurate records. Consulting a local property tax attorney or a qualified assessor can increase the likelihood of a successful outcome.
