Not all Plumbers earn the same — not even close
Missouri's plumbing trade market is anchored by UA Local 562 St. Louis (United Association Plumbers and Pipefitters, ~3,500 active members — one of the largest UA Locals in the Midwest), UA Local 8 Kansas City (~2,500 members), plus regional Locals in Springfield (UA Local 178) and Joplin/Columbia. MO is NOT a right-to-work state (Prop A repealed 2018 referendum) — UA Local pay scales remain competitive vs non-union at $80-105K journeyman base plus substantial OT during commercial + industrial construction cycles. The 2025 No Tax on Overtime federal deduction applies through 2028.

Worth knowing: UA Local 562 St. Louis is one of the largest UA Local plumbing + pipefitting unions in the Midwest at ~3,500 active members. Unlike many right-to-work states, MO's labor environment supports robust UA Local membership — voters REPEALED Prop A right-to-work legislation in August 2018 (67-33 referendum vote, defeating SB 19 of 2017). UA Local 8 Kansas City (~2,500 members) anchors the western MO market. The MO 2025 No Tax on Overtime federal deduction applies to non-exempt OT through 2028 — cap $12,500 single / $25,000 . For a UA Local 562 journeyman at $90K base plus $25K OT premium ($115K total), a single filer's deduction caps at $12,500, worth about $2,750 a year at 22% through 2028. Missouri adds nothing — its DOR says the deduction cannot be claimed on the Missouri return, and because Missouri deducts part of federal tax, the lower federal bill nudges Missouri tax up a few dollars. The 1% city earnings tax in St. Louis AND Kansas City applies to plumber wages earned within city limits — UA journeymen working downtown STL or KC commercial sites pay the additional 1% on city-earned wages. UA Local apprenticeship programs at both 562 (St. Louis) and 8 (Kansas City) run 5-year tracks with ~6,000+ OJT hours plus 880+ classroom hours through community college partnerships.
