Metro District Taxes in Broomfield, Colorado: What Every Buyer Needs to Know
Last Updated: March 2026
A metro district tax is a separate property tax - not your HOA fee - levied by a special government district created to fund the roads, water lines, parks, and community infrastructure that made your neighborhood possible. In Broomfield's master-planned communities like Anthem, Anthem Highlands, and Baseline, metro district taxes appear as a line item on your annual property tax bill, collected by the county alongside every other taxing authority. Every buyer in these communities pays them. Most buyers don't fully understand them until closing day - and by then it's too late to renegotiate your budget.
Here's how they actually work, what they cost by community, and the questions you should be asking before you write any offer in Broomfield.
What Is a Metropolitan District in Colorado?
A metropolitan district - "metro district" for short - is a special-purpose government entity created under Colorado state law (Title 32, C.R.S.) that allows real estate developers to fund large-scale infrastructure before a single home is built. The developer creates the district, the district issues bonds, and those bonds pay for the roads, water and sewer systems, parks, trails, fire protection infrastructure, and community facilities that turn raw land into a livable neighborhood.
Once homes are sold, the homeowners within the district's boundaries repay those bonds through a property tax mill levy - a specific dollar amount per $1,000 of assessed value, added to the annual tax bill every year until the bonds are retired.
Think of it this way: the pool at the rec center, the trails connecting your neighborhood, the park where your kids play - someone had to pay to build all of that before any houses went up. The metro district financed it. You're paying it back over time through your tax bill.
<strong>Metro districts are not HOAs.</strong> They are a separate government entity with the legal authority to levy taxes. Your HOA fee goes to a private association that maintains common amenities. Your metro district tax goes to a government district that services public infrastructure. You pay both.
How the Property Tax Formula Works in Colorado
Colorado property taxes follow a three-part formula:
Actual Value x Assessment Rate x Mill Levy = Annual Property Tax
Here's what each piece means for a Broomfield buyer:
Actual Value is the market value of your home as determined by the Broomfield County Assessor. Property valuations are done every odd year (2025 values apply to tax years 2025 and 2026). The values used in your 2026 tax bill are based on market data collected between July 1, 2022 and June 30, 2024 - a point that confuses many buyers when home prices have shifted.
Assessment Rate is set by the Colorado state legislature and applied to your actual value to get your "assessed value." For tax year 2025, the state set the residential assessment rate at 7.05% for school mill levies and 6.25% for non-school mill levies</strong>. (Source: broomfield.org, Property Tax 101, 2026). The 2024 $55,000 exemption expired and does not apply to 2025 tax bills.
Mill Levy is the total tax rate applied to your assessed value. In Broomfield, your mill levy is the combined total of every taxing authority whose jurisdiction covers your property: the City and County of Broomfield, your school district, North Metro Fire, Urban Drainage, Regional Transportation District, and any metro district in your specific tax area. Mill levies are certified each December and published in January by the Broomfield County Assessor. (Source: Mill Levies by District, broomfield.org, 12/31/2025)
What Metro District Taxes Actually Cost: A Community-by-Community Breakdown
Every property in Broomfield sits in a specific "tax area" with a unique total mill levy. Here's a real-dollar breakdown for Broomfield's three major master-planned communities, using official mill levy data certified as of December 31, 2025.
Important context on Baseline: Baseline is a newer community and its metro district mill levies are higher than Anthem's because the infrastructure debt is newer and less paid-down. This is normal and expected - Anthem's bonds have been retiring for years, Baseline's are early in that cycle. The lower purchase price of Baseline homes partially reflects this higher tax load. Always run the total cost of ownership, not just the purchase price.
Metro District vs. HOA: The Side-by-Side You Need
This is the question I answer more than almost any other in buyer consultations. Here it is clearly:
A Worked Example: What Total Property Costs Look Like in Anthem
Let's put real numbers on a real scenario. You're buying a $700,000 home in Anthem West.
Using official 2025 mill levy data (Tax Area 151, total mill levy 125.946):
Assessed value (school portion at 7.05%): $700,000 x 7.05% = $49,350
Assessed value (non-school portion at 6.25%): $700,000 x 6.25% = $43,750
Blended approximate assessed value: ~$45,500
Total estimated annual property tax: ~$5,700 (using blended assessed value x 125.946 mills)
Of that, the Anthem West Metro District bond levy (18 mills) represents roughly $820/year
Add your HOA: Anthem HOA fees typically run $180-$350/month, or $2,160-$4,200/year.
Combined total annual cost (property tax + HOA): roughly $7,860-$9,900/year on a $700K Anthem home.</strong>
That's your real monthly add-on beyond principal, interest, and insurance: approximately $655-$825/month. Factor this into every budget conversation before you shop. Buyers who skip this step routinely underestimate monthly costs by $300-$500.
Does the Metro District Tax Ever Go Away?
Partially. Metro districts typically levy two types of mill levies:
Debt service mills - these fund bond repayment. As the bonds are paid down over time, the debt service levy decreases and eventually ends. The Anthem West Metro District's debt service mill levy has been declining over time - by 2024, it was 18 mills, down from a higher ceiling authorized in the service plan.
Operations and maintenance mills - these fund ongoing services the district provides. This portion typically continues indefinitely as long as the district operates.
The practical implication: Anthem buyers are in a better position today than buyers 10 years ago, because more of the bond debt has been retired. Baseline buyers are earlier in that cycle and pay higher metro district levies now, with the expectation that those will decrease over time as bonds are paid down.
Mill levies are re-certified every December by each taxing authority and can go up or down. The final numbers for any given year are published by the Broomfield County Assessor in January.
What Colorado Law Requires Sellers to Disclose
This is important. Colorado's rewritten seller disclosure form (SPD19, effective January 2026) specifically includes metro district obligations. <strong>Sellers in Broomfield must disclose the existence of any metro district, the current mill levy, and provide the district's service plan documentation.</strong>
As a buyer, you have the right to review these documents before you close. Red flags to look for:
A metro district with a very high operations and maintenance levy (suggests ongoing service demands)
A district with bonds that are far from retired and a high outstanding balance
A district with no formal service plan or limited public documentation
I pull the metro district certification for every property my buyers are seriously considering. If your agent isn't doing this, ask.
How to Look Up Any Property's Metro District Tax
Go to the Broomfield County Assessor's website (broomfield.org)
Search the property address to find its tax area number
Download the current Mill Levies by District report (updated January each year)
Find your tax area in the report - your total mill levy and each authority's portion will be listed
Use the formula: Home Value x Assessment Rate (~6.25-7.05%) x Mill Levy / 1,000 = Annual Tax
Or email me the property address and I'll run the numbers for you.
Before you write an offer in Broomfield - make sure you have the full tax picture.
Most buyers focus on the purchase price and mortgage payment. The ones I work with also know the full monthly cost of ownership: principal, interest, taxes (including metro district), HOA, insurance, and reserves. If you're shopping in Anthem, Anthem Highlands, or Baseline and want me to pull the real numbers for a specific address, I'll do it.

Frequently Asked Questions
What is a metro district tax in Broomfield, Colorado? A metro district is a government tax district created under Colorado law to fund infrastructure - roads, water, parks, trails - in master-planned communities. Buyers pay a mill levy on their annual property tax bill to repay the bonds that financed that infrastructure. It is separate from, and in addition to, your HOA fee.
How much are metro district taxes in Anthem Broomfield? The Anthem West Metro District bond levy was 18 mills as of December 2025 (Source: Broomfield County Mill Levies, 12/31/2025). On a $700K home, that's roughly $820/year just for the metro district bond portion, out of a total estimated property tax of ~$5,700/year.
Are metro district taxes the same as HOA fees? No. Metro district taxes appear on your annual property tax bill and are collected by the county. HOA fees are paid monthly to a private homeowners association. In Anthem and Anthem Highlands, you pay both. They fund different things and have different legal mechanisms.
Do metro district taxes decrease over time? The debt service portion - which funds bond repayment - can decrease as bonds are retired. Anthem's debt levy has declined over the years as its bonds have been paid down. Baseline's are newer and higher. The operations and maintenance portion may remain ongoing. Mill levies are re-certified each December.
How do I find the metro district for a specific Broomfield property? Look up the property on the Broomfield County Assessor website to find its tax area number, then cross-reference with the annual Mill Levies by District report at broomfield.org. Your agent should pull this for you before any offer is written.
