Rate Breakdown

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

How Property Tax Works in City And Of Broomfield County

Every property in Broomfield County is assigned a taxable value based on its market value on the most recent assessment date, usually January 1. The County Assessor’s Office determines the market value by reviewing recent sales, property characteristics, and any improvements. Once the market value is established, a uniform “assessment ratio” of 10 % is applied, yielding the assessed value that is used to calculate your tax bill.

The actual tax amount is derived by multiplying the assessed value by the combined millage rate for the property’s location. A mill is one‑tenth of one percent (0.001) of the assessed value. In Broomfield, the millage rate is the sum of several components:

• City of Broomfield – funds local services such as police, fire, and streets.
• County – supports the sheriff’s office, courts, and health services.
• School Districts – generally the most significant portion of the rate.
• Special Districts – water, sewer, or library districts may add additional mills.

For example, if the combined millage rate for a residential parcel is 120 mills, the tax due on a $250,000 assessed value would be: $250,000 × 0.00120 = $300.00 annually.

Available Exemptions

Colorado law provides several exemptions that directly reduce the assessed value before the millage rate is applied. Eligibility is determined by the County Assessor, and approved exemptions are reflected on your tax bill.

• Homestead Exemption – All owner‑occupied residences receive a $2,000 reduction in assessed value.
• Senior Citizen Exemption – Residents age 65 + may qualify for a $50,000 exemption if they meet income limits (generally $75,000 household income).
• Disability Exemption – Qualified disabled persons can receive a $25,000 exemption, with additional $1,000 per dependent.
• Veteran Exemptions – Armed forces veterans may claim a $50,000 exemption for a primary residence, plus an additional $25,000 for a surviving spouse.

Applications for these exemptions are filed with the Broomfield County Assessor’s Office, typically by March 1 of the tax year. Supporting documentation (proof of age, disability rating, veteran status, etc.) must be included.

Payment Schedule & Deadlines

Property taxes in Broomfield County are due in two installments. Timely payment avoids penalties and preserves your good standing with the county.

• First Installment – Due by March 15. It covers the portion of the tax bill that is due for the first half of the fiscal year.
• Second Installment – Due by October 15. This final payment settles the remaining balance.
• Late Payments – A 5 % penalty plus interest accrues after the due date. Continued delinquency can result in tax lien placement and eventual foreclosure.
• Payment Options – Payments can be made online via the County Treasurer’s portal, by mail, in person at the Treasurer’s office, or through authorized third‑party providers. Some lenders also collect taxes through escrow accounts.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, you have the right to protest. The appeal process in Broomfield County follows a strict timeline and procedural steps.

• Notice of Unconditional Protest – File this form with the County Assessor’s Office by July 31 of the assessment year. No supporting evidence is required at this stage.
• Notice of Conditional Protest – Submit a detailed protest, including comparable sales, appraisal reports, or error corrections, by August 31. Attach all supporting documentation.
• Hearing – The Broomfield County Board of Assessment Appeals will schedule a hearing, usually in September. You may present your case in person or by written statement.
• Decision – An official written decision is issued within 30 days of the hearing. If you disagree with the outcome, you may appeal to the Colorado Board of Assessment Appeals.

Retaining a qualified property tax consultant or attorney can improve the odds of a successful protest, especially for complex commercial properties or significant assessment discrepancies.
