In short

  • The tax office collected about $3.1 billion for other local governments in one year.1
  • It paid about $3.05 billion of that to those governments.1
  • Its fees brought the county about $12.2 million. Its own budget spent about $5.3 million.23

What the office does

The county tax office is run by the Tax Assessor-Collector. It collects county property taxes. It also collects taxes for many cities and districts in the county. It titles and registers cars and collects state and county fees.4

Money it holds for others

This money is not the county’s. The county keeps it in a separate account until it is paid out.1

Fiscal 2025 (year ended Sept. 30, 2025)Amount

The office’s own fees and costs

These two lines are in the county’s main fund.

Fiscal 2025BudgetActual
Fees the office brought in$11,606,000$12,229,7222
Office spending$5,900,189$5,310,2863

The fees came in about $624,000 over budget.2 The office spent about $590,000 less than its budget.3

The other side

  • The tax money is not the county’s. The county holds it in a separate account and pays it out to cities, schools and other districts.1
  • Fees and costs are not a profit figure. The audit compares fees with the office’s own budget line. It does not show whether that line holds all of the office’s costs, such as buildings or shared staff.23

What we still don’t know

  • How these amounts changed after fiscal 2025. The county’s audit for fiscal 2026 would show it. We have not seen it yet.

Questions to ask

  • How long does the tax office hold tax money before it pays it out?
  • Who keeps the interest earned on the money the tax office holds?
  • Which tax office costs are paid from other county budget lines?
