Rate Breakdown

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

How Property Tax Works in Lake County

Lake County property taxes are calculated by multiplying the assessed value of your real‑estate by the cumulative millage rate set by the county and its taxing authorities. The Colorado Department of Local Affairs first determines the market value of a property at the time of sale or, for non‑sale years, at the county’s annual reassessment. This market value is then reduced by a statutory assessment ratio (usually 7.15 % for residential property) to arrive at the “assessed value.”

The assessed value is the base figure that each taxing district (county, school district, fire protection, water & sewer, etc.) applies its millage rate to. A mill is one‑tenth of one percent, or $1 of tax per $1,000 of assessed value. For example, if Lake County’s total millage for a given year is 120 mills (0.120), a home assessed at $200,000 would owe $24,000 × 0.120 = $2,880 in property taxes.

Millage rates can vary each year based on budgetary needs, voter‑approved bonds, and state legislative changes. The Lake County Assessor’s Office posts the current rates on its website and includes a breakdown of how each district’s portion contributes to the total.

Available Exemptions

Colorado offers several exemptions that can lower the taxable portion of your assessment. In Lake County you may qualify for one or more of the following:

• Homestead Exemption: 100 % of the first $200,000 of the market value of a primary residence is exempt from assessment, effectively reducing the taxable base.
• Senior Citizen Exemption: Residents age 65 or older may receive an additional $500,000 exemption on the market value of their home, provided the homeowner’s total income does not exceed the state‑defined limit.
• Disability Exemption: Qualified persons with a permanent physical or mental disability can claim a $300,000 market‑value exemption, subject to income testing.
• Veteran Exemption: Veterans who served on active duty and have a service‑connected disability may be eligible for a $500,000 exemption on the market value of their primary residence.

To claim any exemption, submit the appropriate application to the Lake County Assessor’s Office by March 1 of the tax year. Supporting documentation—such as proof of age, disability rating, or veteran status—must accompany the request.

Payment Schedule & Deadlines

Lake County property taxes are due in two installments:

• First installment: Due October 15. This covers the first half of the annual tax bill.
• Second installment: Due January 15 of the following year. This completes the remaining balance.

If you prefer, you may set up an automatic monthly debit with the county treasurer, spreading the liability across twelve equal payments. Early payment discounts are not offered, but paying on or before the due dates avoids the statutory late‑payment penalty of 5 % plus interest, which accrues daily after the deadline.

Unpaid taxes become a lien on the property, and after 90 days of delinquency the county may initiate tax‑sale proceedings. Prompt payment or enrollment in a payment‑plan agreement with the treasurer’s office is essential to protect your ownership rights.

Appealing Your Assessment

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

• Step 1 – Review: Examine the assessor’s notice and compare the market value to recent sales of comparable properties.
• Step 2 – File a Petition: Submit a written appeal to the Lake County Assessment Review Board (ARB) within 20 days of receiving the notice. Include supporting evidence such as appraisals, sales data, and photographs.
• Step 3 – ARB Hearing: The board will schedule a hearing, usually within 30 days of the petition. You may present your case in person or via a designated representative.
• Step 4 – Decision: The ARB issues a written decision. If dissatisfied, you can appeal the board’s ruling to the Colorado Board of Assessment Appeals within 30 days.

All appeals are free of charge, but you must meet the filing deadlines. Keeping records of your property’s condition and recent market activity will strengthen your case.
