Boulder County property owners, brace yourselves for a squeeze on your wallets this year, with the former $55,000 relief on residential value assessment now a thing of the past and a new two-tier tax rate system kicking in, a significant shift in how property taxes will be doled out for 2025, bills payable come 2026. According to Boulder County, the temporary measures that were once a financial cushion are no longer in play, potentially ramping up tax bills even if property valuations haven't wavered much.
The blow will be felt most by owners of manufactured homes; the removal of the valuation reduction could double their tax bills, with an example given where a home valued at $100,000 would see its tax jump from around $275 in 2024 to approximately $550 in 2025, the two-rate system for residential properties separating the levies for schools at 7.05% and other local governments at 6.25%, which means you'll be calculating your taxes in two slices this year, one for educational coffers and another for various local governmental needs and this isn't a mistake, but rather the new normal for the foreseeable future.
For those wondering about their options come payment time, Boulder County has laid out the schedule with a two-installment plan set for March 2 and June 15, or a full payment deadline slated for April 30 of the same year. Looking at nonresidential properties, like commercial and agricultural lands, the county details a valuation for assessment at 27%, which is described as a reduction from the previous 29%, according to Boulder County Assessor Cynthia Braddock's statement, "If you have questions about your value notice, the new split residential rates, or want guidance in how to appeal your tax bill, please reach out. We are here to help you understand your information and your options," as per Boulder County.
For elderly Boulder residents and those active in the military, a glimmer of relief still exists with the tax deferral applications being taken by the Boulder County Treasurer's Office, an adjustment that became effective as of 2025, the rolling process handles by the counties with deferral loans managed by the Colorado State Treasurer's Office, those interested should make their moves between January and mid-March to apply for this support, reachable via phone or email to the treasurer's office, the new calculation for your 2025 property tax bill will consider the actual value, the aforementioned fresh assessment rates, and the mill levy, setting the stage for your total sum payable for schools and other local governance which are first shown separately, then collectively added to give you the total you owe.
