Larimer County Property Tax Rate: How It Is Calculated
The Larimer County property tax rate is not one flat number for every home. Your bill depends on your home's assessed value and the taxing districts that serve your address.
The Larimer County property tax rate is usually expressed as an effective rate, which is the share of a home's value that goes to property tax. That percentage lets you compare homes at different prices on the same footing, so it is the number to look at first.
Third-party trackers report an effective rate of about 0.52% for a Larimer County example. [1] Fort Collins is reported at 0.57%. [2] Those figures are estimates from outside sites, so use them as a starting point rather than an exact bill.
This article walks through how your bill is built, from assessed value to the taxing districts that share it, and what to add to your monthly housing cost.
How is my property tax calculated in Larimer County?
Your Larimer County property tax bill starts with two things: your home's assessed value and the combined levies of every taxing district that covers the property. Both pieces matter, so you need to know which districts apply to the home you're considering. [3]
Assessed value and levies
The assessed value is the figure the county uses as the base for your tax. A home with a higher assessed value owes more, even if the levies stay the same. Think of it as the starting point, and the levies as the multiplier that turns it into a bill.
The levies come from each taxing district that covers the property. Each district sets its own levy, and your total is the sum of all of them. That is why two bills for similar homes can differ.
Districts make the difference
Districts differ from one area to the next, so two homes with the same price can carry different bills if they sit in different districts. Compare homes by district, not by price alone. A home in a metropolitan district, for example, is subject to that district's charges on top of the county's and other local taxes. [3]
If you are comparing two homes in the same neighborhood, check whether they fall in the same districts before you assume their bills will match. A home on the edge of a town can sit in a different set of districts than one a few streets away.
Use the county's calculator
The Larimer County Treasurer offers an online tool called Calculate Property Taxes Due, which works out the taxes due for a specific property. Because the bill is set property by property, run the tool for each home on your list rather than relying on a neighbor's figure. [4]
Open the tool from the Treasurer's website, enter the property you are considering, and read the taxes due it returns. Write down the annual figure for each home so you can compare them side by side. Those results give you a more reliable number than an estimate from a general website.
What do effective rates look like for real homes?
The effective rate is the share of a home's value that goes to property tax each year, so it lets you compare homes at different prices.
Fort Collins is reported at 0.57%, which is above the Colorado state median of 0.50% but well below the national median of 1.02%. [2] On the same home value, Fort Collins would carry a slightly larger bill than the typical Colorado home, and a much smaller one than the typical U.S. home.
Because the effective rate is a percentage, a higher home value raises the bill even when the rate stays the same. If a home sells for more, the same rate applies to a bigger number, so the annual tax grows.
Where does your property tax bill go?
Larimer County's share is only one slice of your property tax bill, so the county rate alone does not show what you will pay. For most districts inside a municipality, Larimer County receives about 25% of your total property tax payment [3]. The county figure is useful, but it is not the whole bill.
The split changes with location. In the Town of Timnath, the town received about 4% of the average property tax bill paid in 2022 [5]. On a home assessed at $460,000, that came to about $215 [5].
The rest of the bill goes to other local taxing bodies that levy on the same property. Each one adds its own levy, so the total depends on every district that covers the address.
This matters when you compare two addresses. Two homes at the same price can carry very different bills if they sit in different districts. A county share that looks large in one place can be a small part of the total in another.
Work through it in this order:
- Get the total property tax figure for the specific address.
- Find out which taxing districts cover that address.
- Compare the full totals across the homes you are considering, not the county percentage.
Use the county figure as one input, not the answer. The districts that cover the address decide how much the county share represents of what you actually pay. If you are choosing between two Fort Collins homes, the full bill for each one is the number to compare.
How much should you add to your monthly housing cost?
To add property tax to your monthly housing cost, divide the annual tax bill by 12. The result is the amount to add to your mortgage payment each month.
For example, a Larimer County home at $610,000 shows $3,146 in annual property tax, with an effective rate of 0.52% [1]. Divided by 12, that is about $262 per month.
How to run the numbers
- Find the annual property tax for the specific home you are considering.
- Divide that annual amount by 12.
- Add the result to your principal and interest payment.
Get the number for your home
Each property has its own assessed value and sits in its own taxing districts, so the tax on a different home can be higher or lower.
The Larimer County Treasurer's Calculate Property Taxes Due tool gives the figure for a specific property [4]. Run it for each home on your list before you settle on a monthly budget. Then divide that annual result by 12 using the steps above.
What should you take away about Larimer County property taxes?
The Larimer County property tax rate is applied to assessed value, so your actual bill depends on the specific home and the taxing districts it sits in. Reported effective rates of roughly 0.5% to 0.6% are far below the national median of 1.02%, but those figures come from outside estimates, not the county. [1][2]
Before you set your monthly budget, run the county treasurer's calculator for the exact property you are considering. It is the Calculate Property Taxes Due tool on the Larimer County Treasurer's site, and it gives a figure for that home rather than an average. [4]
