Pennsylvania Minimum Wage Rules: 43 P.S. § 333.104, Local Preemption & Back Pay
An authoritative legal guide to Pennsylvania’s statutory $7.25 per hour wage floor, the mechanics of statewide municipal preemption, Philadelphia contractor wage rules, and the statutory formula for back-pay recovery.
Direct Answer Summary
The statutory minimum wage in Pennsylvania is $7.25 per hour for all non-exempt private-sector employees. Under 43 P.S. § 333.105, Pennsylvania law preempts cities and counties from establishing higher local minimum wages for general private employers. Philadelphia’s 21st Century Minimum Wage Standard ($17.63/hr for new, amended, or renewed contracts in FY27 effective July 1, 2026; $16.82/hr for transitional FY26 contracts; $16.35/hr for FY25 contracts; $12.40/hr in calendar 2026 and $15.51/hr in calendar 2025 for qualifying unamended contracts executed on or before April 18, 2019) applies only to municipal contracts, city leaseholders, and subsidized entities. Any hour paid below $7.25 constitutes an unlawful wage underpayment enforceable through the Pennsylvania Wage Payment and Collection Law (WPCL).

1. The Statutory Baseline: 43 P.S. § 333.104
The governing statute for minimum wages across the Commonwealth of Pennsylvania is the Pennsylvania Minimum Wage Act of 1968 (PMWA), enacted as P.L. 11, No. 5 and codified at 43 P.S. §§ 333.101–333.115.
Under 43 P.S. § 333.104(a), the standard minimum wage rate matched the federal Fair Labor Standards Act (FLSA) rate on July 24, 2009, establishing a base rate of $7.25 per hour. Unlike neighboring jurisdictions such as New York, New Jersey, Maryland, or Ohio, Pennsylvania does not index its minimum wage to changes in the Consumer Price Index (CPI), nor has the General Assembly enacted a statutory step schedule.
2. Statewide Municipal Preemption (43 P.S. § 333.105)
A frequent source of worker confusion in Pennsylvania is whether municipalities like Philadelphia, Pittsburgh, Allentown, or Erie can mandate higher wage rates for local workers.
Pennsylvania applies strict statutory preemption under 43 P.S. § 333.105. The statute explicitly specifies that the PMWA establishes exclusive statewide standards for minimum wages. Consequently, municipal ordinances attempting to mandate higher private-sector minimum wages are invalid and unenforceable against general commercial employers.
The Philadelphia 21st Century Minimum Wage Exception
In Philadelphia, the City Council enacted the 21st Century Minimum Wage Standard (Philadelphia Code Chapter 17-1300), which adjusts minimum compensation annually for covered city contracts based on CPI. Under official City of Philadelphia Finance Department wage schedule letters:
- FY27 Standard ($17.63/hr): Effective July 1, 2026, for qualifying new, renewed, or amended covered city service contracts, leases, and concessions, as well as multi-year / long-term contracts entered into on or after April 19, 2019 subject to annual escalation under Philadelphia Code § 17-1305.
- FY26 Transitional Standard ($16.82/hr): Applicable to qualifying FY26 contracts during legally applicable transitional terms.
- FY25 Standard ($16.35/hr): Applicable to qualifying FY25 contracts effective July 1, 2024 through June 30, 2025 during their historical term.
- Grandfathered Pre-April 19, 2019 Contracts ($12.40/hr in 2026 / $15.51/hr in 2025): Applicable strictly to qualifying unamended contracts originally executed on or before April 18, 2019 (under official FY27 letter Footnote 2 and FY26 letter). Execution date alone is insufficient without verified continuity/absence of intervening amendment, and absence of amendment alone does not establish pre-April-2019 execution.
- Unverified / Historical Contracts: Older contracts without verified execution terms, duration, renewals, or unamended status fail closed as unverified rather than assuming an arbitrary rate.
Because of state preemption under 43 P.S. § 333.105, this standard applies only to direct municipal contractors, airport concessionaires, leaseholders on city property, and designated financial aid recipients. General private employers in Philadelphia remain governed exclusively by the state $7.25 statutory rate.
3. The Mathematical Back-Pay Formula
Under Pennsylvania Department of Labor and Industry guidelines and the WPCL, back pay represents the difference between mandatory statutory earnings and confirmed gross earnings received.
Required Gross Wages = Regular Hours Worked × Applicable Rate ($7.25)
Confirmed Shortfall = max(0, Required Gross Wages - Confirmed Actual Gross Wages)
Worked Numerical Examples
Employee works 40 hours at the statutory rate of $7.25/hr. Required gross wages = 40 × $7.25 = $290.00. If employer pays $290.00, confirmed shortfall = $0.00 (Fully Compliant).
Employee works 20 hours and is paid an unlawful rate of $6.50/hr ($130.00 gross). Statutory earnings floor = 20 × $7.25 = $145.00. Confirmed shortfall = $145.00 - $130.00 = $15.00 in back wages owed.
Employee works 20 hours, but actual pay stubs are unavailable. Required earnings floor = $145.00. Under StateWageCalc.com standards, the calculator marks status as Payment Unverified rather than assuming zero payment and fabricating a $145 shortfall.
4. Common Misconceptions About PA Minimum Wage
- Misconception 1: "Philadelphia has a $15.00 minimum wage for everyone."
As discussed above, state preemption prohibits Philadelphia from regulating general private commerce. Unless you work under a municipal city contract, the state minimum is $7.25. - Misconception 2: "Tips can reduce an employer’s direct cash wage below $2.83."
Even if a server earns hundreds of dollars in tips, Pennsylvania law requires the employer to pay at least $2.83/hr in direct cash wages (34 Pa. Code § 231.101a). Tips never eliminate this cash wage obligation. - Misconception 3: "Pennsylvania requires daily overtime after 8 hours."
Pennsylvania has no statutory daily overtime standard. Overtime is calculated solely on hours exceeding 40 in a 7-day workweek.
