What Are Property Taxes in Littleton, CO? A Complete Guide for Homebuyers

By Bryan Messick, REALTOR®, AI Certified Agent™ & Littleton Lifestyle Specialist

Property taxes are one of the largest ongoing costs of homeownership — and one of the most confusing for buyers to estimate. Unlike a mortgage payment, which is predictable, property taxes can vary significantly depending on which county your home is in, which school district serves it, and which special districts (fire, water, recreation) apply.

Littleton spans three counties — Jefferson, Arapahoe, and Douglas — which means property tax rates can differ from one neighborhood to the next. Here is a complete guide to understanding and estimating property taxes in Littleton, CO.

How Colorado Property Taxes Work

Colorado property taxes are calculated using a three-step formula:

1. Actual Value: The county assessor determines the market value of your property. This is reassessed every two years (in odd-numbered years).
2. Assessed Value: For residential property, the assessed value is approximately 6.95% of the actual value. (This percentage — the "residential assessment rate" — is set by the state legislature and can change.)
3. Mill Levy: The assessed value is multiplied by the mill levy for your tax district. One mill = $1 per $1,000 of assessed value. The mill levy is the sum of all taxing entities: county, school district, fire district, water district, recreation district, and any special districts or bond approvals.

The formula: Actual Value × 6.95% × Mill Levy ÷ 1000 = Annual Property Tax

Example: Property Tax on a $725,000 Home in Littleton

Let's calculate the approximate annual property tax on Littleton's median single-family home price of $725,000:

• Actual value: $725,000
• Assessed value (6.95%): $50,388
• Typical mill levy (varies by district): 85–110 mills
• Annual property tax: $4,283 to $5,543

On a monthly basis, that is approximately $357 to $462 per month added to your mortgage escrow payment. This is why it is critical to include property taxes in your affordability calculations — not just the principal and interest.

Littleton Spans Three Counties — Here is How They Differ

The mill levy varies depending on which county and tax district your home falls in:

• Jefferson County: Most of central and western Littleton, including Ken Caryl and Columbine. Mill levies typically range from 85 to 100+ mills depending on the specific district.
• Arapahoe County: Parts of eastern Littleton, including some areas of Highlands Ranch that use a Littleton mailing address. Mill levies are generally in a similar range.
• Douglas County: Highlands Ranch and some southern Littleton areas. Douglas County tends to have slightly different mill levies due to different school district and special district structures.

The exact mill levy for any property can be found on the county assessor's website or in the MLS listing. Always verify the current tax amount for any property you are considering — do not rely on estimates.

Property Tax Reassessment: What to Expect

Colorado counties reassess property values every two years, in odd-numbered years (2025, 2027, etc.). The reassessment reflects market conditions as of January 1 of that year, based on sales from the prior two-year period.

This means your property taxes can increase (or decrease) after a reassessment, even if your tax rate does not change. If home values in your area have risen significantly, your assessed value — and your tax bill — will likely go up at the next reassessment.

Colorado has a Gallagher Amendment mechanism and TABOR (Taxpayer's Bill of Rights) that interact to limit property tax growth in some ways, but the details are complex. The practical takeaway: budget for property tax increases at each reassessment cycle, especially in appreciating neighborhoods.

How Littleton Compares to Nearby Communities

Property taxes in Littleton are generally comparable to nearby Denver metro communities. The differences between Littleton, Highlands Ranch, Centennial, and Lakewood are typically modest — a few hundred dollars per year on similar-valued homes — and are driven by differences in school district mill levies and special district assessments.

Compare Littleton vs. Highlands Ranch, Littleton vs. Centennial, or Littleton vs. Lakewood for a full cost comparison.

Property Tax Exemptions and Reductions

Colorado offers several property tax exemptions that may reduce your bill:

• Senior Homestead Exemption: Available to homeowners 65+ who have owned and occupied their home as their primary residence for at least 10 consecutive years. This exempts 50% of the first $200,000 of actual value.
• Disabled Veteran Exemption: Available to veterans with a permanent disability rating of 100%.
• Property Tax Exemption for Veterans: Certain disabled veterans may qualify for a partial exemption.

These exemptions are subject to state budget availability and may be suspended in some years. Check with the county assessor for current availability.

How to Find the Property Tax for a Specific Littleton Home

The most accurate way to find the property tax for a specific home is to look up the parcel on the county assessor's website:

• Jefferson County: jeffco.us assessor's office
• Arapahoe County: arapahoegov.com assessor's office
• Douglas County: douglas.co.us assessor's office

Always verify the actual tax amount for any property you are considering — estimates can be off by hundreds of dollars depending on the specific tax district.
