The Canyon County Prosecuting Attorney’s Office is pushing for a revised financial arrangement with the City of Caldwell over misdemeanor prosecutions, arguing that county taxpayers have been left to absorb costs that Idaho law places squarely on cities to fund.
Background: Who Pays for Misdemeanor Cases?
Under Idaho law, cities are responsible for funding the prosecution of misdemeanor cases originating within their boundaries. Canyon County handles that work countywide, but the cost-sharing agreements between the county and individual cities determine how much each city reimburses. Canyon County Prosecuting Attorney Chris Boyd has made closing that gap a priority.
The county currently spends roughly $2.4 million annually to prosecute misdemeanor cases across all of Canyon County. Caldwell generates a significant share of that workload — about 22.9% — yet under the previous contract, the city was reimbursing only 7% of the total cost back to the county.
That imbalance meant Caldwell’s fair share of the bill last year would have totaled approximately $569,000, but the city paid just over $350,000 — leaving other Canyon County taxpayers to make up a shortfall of more than $218,000.
Boyd Points to Nampa Agreement as a Model
Boyd has already worked through a similar renegotiation with Nampa, the county’s largest city. That effort produced what his office describes as a reasonable cost-sharing structure, and Boyd indicated he is seeking the same outcome with Caldwell.
“We worked with Nampa last year and they now do pretty reasonable cost-sharing with us,” Boyd said. “I appreciate Caldwell’s understanding that costs need to be fairly reimbursed.”
The quote suggests some level of ongoing dialogue between the two governments, though the specifics of any new Caldwell contract have not yet been finalized. The prosecutor’s office said it intends to pursue proportionate reimbursement going forward. For Canyon County residents and taxpayers in smaller communities who have no hand in generating Caldwell’s caseload, the current arrangement amounts to a quiet subsidy flowing to Idaho’s third-largest city.
Impact on Canyon County Residents
The financial stakes are real for families across Nampa, Middleton, and unincorporated Canyon County who have no connection to Caldwell’s municipal courts but whose tax dollars help fund its misdemeanor prosecutions. Canyon County commissioners and local officials have increasingly focused on ensuring that city governments carry their fair share of shared services — a concern that mirrors broader fiscal conversations happening across the Treasure Valley as population growth strains public budgets.
The prosecuting attorney’s push aligns with a principle of fiscal responsibility that many Canyon County residents support: government costs should be borne by the jurisdiction that generates them, not spread across the broader taxpayer base. For context on how law enforcement and public safety funding decisions play out at the local level, the Caldwell Police Department has recently drawn attention for its own service record — officers were recognized earlier this year for their actions during a high-risk incident. The quality of law enforcement and the funding of prosecution are connected pieces of the same public safety system.

What Comes Next
The Canyon County Prosecuting Attorney’s Office has indicated it will continue working toward a proportionate cost-sharing agreement with Caldwell. Whether the city and county reach a new contract — and at what reimbursement level — remains to be seen. Canyon County taxpayers and city officials in Caldwell will both have a stake in the outcome. Boyd’s office has framed the goal as fairness, not conflict, and the precedent set by the Nampa agreement suggests a workable path forward if both sides engage in good faith.
