Pennsylvania constables are not salaried employees of any government body. They cover 100% of the cost of running the office out of pocket: training, firearms qualification, body armor, duty belt, radio, ammunition, professional liability insurance (statutorily required), and a transport vehicle that meets AOPC equivalency standards including a prisoner cage.
From the same per-service fee income, constables pay 15.3% self-employment tax on top of ordinary income taxes — with no employer contribution, no benefits, no pension, no sick leave, no workers' compensation. The statutory fee schedule covering judicial duties has not kept pace with inflation.
The cost to taxpayers is real, even though constables aren't paid by the state. Unwarranted prosecutions cost both the constable (legal defense) and the Commonwealth (prosecution) thousands per case — for charges that get dismissed or end in acquittal. Pennsylvania ends up paying twice for the privilege of attacking its own elected officers.
Make the office expensive enough and only wealthy people can afford to run for it. Make it impossible to budget for and no one runs at all. Either way, communities lose locally elected law enforcement.
