Plumber Salary in Pennsylvania (2026)

Worth knowing: UA Local 690 Philadelphia is one of the larger UA Local plumbing unions in the Mid-Atlantic at ~3,500 active members. PA's non-RTW status + substantial trades-friendly political environment supports robust UA Local membership. The 2025 OBBBA No Tax on Overtime federal deduction applies to non-exempt plumber OT premium pay through 2028 — cap $12,500 single / $25,000 MFJ. At $25K OT premium, OBBBA produces ~$5,500 federal + ~$1,225 PA savings (4% Philly residents get additional benefit from city wage tax application on the after-deduction base) = $5,500-$6,725 cumulative through 2028. The PA 401(k) state non-conformity affects active-career income — PA does NOT allow federal pre-tax 401(k) deferral to be excluded from PA-taxable wages. A senior UA journeyman at $120K maxing federal 401(k) at $24,500 saves federal but $0 PA. Roth 401(k) is the structural workaround. The critical late-career benefit: PA does NOT tax retirement distributions (401(k)/IRA/pension/UA Local pension) at withdrawal — combined with the substantial UA Local defined-benefit pension benefits, PA-resident UA Local journeymen running Roth 401(k) during active career achieve some of the most favorable US trade-worker retirement math. The Philadelphia City Wage Tax 3.79% catches Philly-area UA journeymen working at city construction sites; the 6-state reciprocity (NJ + MD + VA + OH + WV + IN) makes Philly cross-river commute from Cherry Hill NJ workable.
