Lower your Larimer County property taxes
The Larimer County Assessor revalues homes in Fort Collins, Loveland, Windsor, Estes Park and the rest of the county every two years, and 2027 values will reflect the market as of June 30, 2026. The 2025 median barely moved, but most values shifted anywhere from −6% to +6%, so your home may not match the countywide picture. 30% of first-year savings, only if you save.
What a too-high value costs you
If your home is assessed at $550,000 but similar homes point to about $515,000, you're taxed on $35,000 too much. At a 0.63% rate that's about $221 a year. Our fee would be $66; you'd keep $154.
What gets missed in Larimer County
- The 2027 reappraisal. Every home gets a new value in May 2027, based on sales up to June 30, 2026. Each reappraisal is a fresh chance to protest.
- Town-by-town differences. 2025 medians ranged from $471,000 in Wellington to $824,000 in Windsor. Comparisons across towns can mislead.
- Mountain and rural homes. Homes near Estes Park or Red Feather Lakes have few close sales, so values can lean on poor matches.
- Condition. An original kitchen, an aging roof or a cracked foundation doesn't show up in the assessor's records.
Insider tip: Larimer offers Zoom appointments as well as online filing during the appeal window. Bring sales of similar homes in your town from before June 30, 2026.

Exemptions to check
If you're 65 or older and have owned and lived in your home for at least 10 years, the senior exemption takes 50% off the first $200,000 of actual value. Qualifying disabled veterans get the same exemption. For 2026, the local-government part of your tax is figured on your value minus 10% of the first $700,000.
