Who sends the property tax bill in Broomfield County, and how do you pay it?
The bill comes from the City and County of Broomfield Treasurer's Office. The value it is based on is set by a separate office, the City and County of Broomfield Assessor, which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.
Broomfield is a combined city and county, so one bill from the Treasurer covers the city and county, school district and special districts; there is no separate city property tax bill. Colorado taxes are paid a year behind: the notice sent around the third week of January 2027 is for 2026 taxes, and it goes to the owner, not the mortgage company. Colorado revalues homes in odd-numbered years, so new values arrive with the May 2027 notice of value. Online card payments carry a 2.50% provider fee and eCheck payments a $2.50 fee.
When are property taxes due in Broomfield County?
For the 2026 taxes payable 2027 bill, Broomfield County splits the bill into 3 payments, the first due February 28, 2027 and the last June 15, 2027. Late payments are charged interest of 1% a month under state law: from March 1 on a late first half, from June 16 on a late second half, and from May 1 when the whole bill is paid in one payment after April 30.

Unpaid taxes are normally advertised in October, which adds charges, and a tax lien is sold in early November; paying by the end of September avoids those charges.
| Payment | Due | Note |
|---|---|---|
| First half (two-payment option) | February 28, 2027 | February 28, 2027 is a Sunday. State law makes a payment due on a Saturday, Sunday or legal holiday on time if made the next business day, Monday, March 1. For a mailed payment, the U.S. Postal Service postmark date counts as the date received; the county suggests asking the postal clerk for a hand-stamped postmark so it matches the day you mail it. |
| Full payment (one-payment option) | April 30, 2027 | Instead of two halves, the whole bill can be paid in one payment by April 30. A bill under $25 must be paid in one payment. |
