How to Choose a Payroll Company or PEO in Pennsylvania

Payroll software, payroll services, and PEOs

Pennsylvania payroll runs through the Department of Revenue and the Department of Labor & Industry, then adds a local tax layer that changes with an employee’s home and work address.

There are three models to choose from. The difference is how much of the work you keep and whether the provider becomes a co-employer.

• Payroll software. You operate the system and keep the state and local registrations in your company’s name. The software calculates withholding and files returns when the plan includes Pennsylvania and local tax filing. More on payroll and HR software
• A payroll service. A payroll bureau runs payroll and files under your employer accounts. In Pennsylvania, ask specifically whether the service handles PSD codes, Act 32 local earned income tax, Local Services Tax, and Philadelphia or Pittsburgh filings where they apply. More on payroll services
• A PEO. A professional employer organization becomes a co-employer and bundles payroll, benefits, workers’ compensation, and HR administration. Pennsylvania still keeps unemployment compensation on the client’s account and rate. More on PEOs

A payroll service can take over the filing work without changing who the employer is. A PEO changes the employment arrangement, but Pennsylvania’s unemployment rules still treat the client as the UC employer of covered workers.

What Pennsylvania costs an employer in 2026

Pennsylvania unemployment compensation uses a $10,000 taxable wage base. The Department of Labor & Industry’s 2026 rate table sets the newly liable non-construction rate at 3.822% and the construction rate at 10.5924%. Experienced employers range from 1.4190% to 10.3734%.

Employees also contribute 0.07% of gross wages to unemployment compensation in 2026. The employee contribution rule has no taxable wage ceiling, so the employee-side amount keeps running after the employer reaches the $10,000 wage base.

Take a non-construction employee earning $60,000 at a newly liable Pennsylvania employer. State-only employer payroll taxes stop at the UC wage base, while employee withholding continues on gross wages.

Social Security and Medicare are federal and excluded from the comparison. Workers’ compensation varies by classification and payroll, and Pittsburgh adds a separate Payroll Expense Tax for work performed in the city.

Unemployment compensation

Pennsylvania calls its unemployment system UC. The 2026 Yearly Tax Highlights set a 9.2% surcharge adjustment and a 0.60% additional contributions tax for experienced employers. Those amounts are already built into the published 1.4190%–10.3734% total rate range, and the 2026 interest factor is 0.00%.

The new-employer schedule sets a newly liable non-construction employer at 3.8220% and a newly liable construction employer at 10.5924%. Those rates apply to the first $10,000 of each employee’s wages, and the Department of Labor & Industry says the new-employer contribution rate applies for the first two or three calendar years that the employer pays wages.

The 2026 Yearly Tax Highlights say newly liable employers do not pay the 0.60% additional contributions tax unless the account is also subject to a delinquency increase. For 2026, an employer with a delinquency through the second quarter of 2025 can have 3% added to its basic contribution rate before the 9.2% surcharge is applied.

Quarterly wage and tax reports are filed electronically through UCMS. The quarterly filing schedule sets April 30, July 31, October 31, and January 31 as the regular due dates.

Pennsylvania is also one of the states that withholds an unemployment contribution from employees. The 2026 Yearly Tax Highlights set the employee contribution at 0.07% of total gross wages with no wage cap. The employer’s $10,000 taxable wage base does not limit the employee contribution.

State income tax withholding

The Pennsylvania Department of Revenue requires employers to withhold 3.07% of compensation from resident employees and from nonresident employees earning taxable wages in Pennsylvania. Residents of reciprocal states can be exempt from Pennsylvania withholding when the required certificate is on file and the employer withholds the resident state’s income tax instead.

The Pennsylvania Department of Revenue sets deposit frequency from the amount of tax withheld. Employers expected to withhold less than $300 per quarter remit quarterly, $300–$999 monthly, $1,000–$4,999.99 semimonthly, and $5,000 or more per quarter or $20,000 or more per year semiweekly.

Every withholding account still files a quarterly reconciliation. The frequency changes when the Department of Revenue reevaluates an employer’s reported withholding for the next calendar year.

Residents of six reciprocal states

Pennsylvania has reciprocal compensation agreements with Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia. A resident of one of those states working in Pennsylvania can file Form REV-419 to stop Pennsylvania personal income tax withholding when the employer agrees to withhold and remit the employee’s resident-state income tax instead.

The Department of Revenue employer guide requires the employer to withhold the reciprocal state’s tax when it accepts the exemption. The agreement applies to state personal income tax. Pennsylvania local earned income tax still follows the employee’s home and work locations.

Local earned income tax

Local earned income tax is what separates Pennsylvania payroll from most states. Under Act 32 employer guidance, an employer compares the employee’s total resident EIT rate with the work-location nonresident EIT rate and withholds the higher of the two.

Each employee completes a Residency Certification Form showing the six-digit political subdivision, or PSD, code for the home and work locations. The DCED address lookup returns the resident rate, work-location rate, Local Services Tax, and the tax collectors tied to those addresses.

Employers register with the local collector for the worksite tax collection district. DCED employer instructions require quarterly local EIT returns and remittances within 30 days after each calendar quarter, followed by the W2-R annual reconciliation by the last day of February.

An address change can change the PSD code and the withholding rate without changing the employee’s employer. Payroll therefore needs an address-driven local-tax setup for each employee.

Local Services Tax

Pennsylvania municipalities and school districts may also levy a Local Services Tax. The Department of Community and Economic Development caps the combined annual amount at $52 for one taxpayer.

DCED’s Local Services Tax guidance requires an LST above $10 to be spread across payroll periods. A $52 tax comes out to $1 per weekly payroll or $4.33 per monthly payroll, subject to the statutory rounding rule.

The same DCED guidance requires a jurisdiction charging more than $10 to provide a low-income exemption for a worker whose earned income and net profits from all sources in that jurisdiction are under $12,000. Once an employee gives the employer an exemption certificate, withholding stops unless the employee later crosses the threshold or the tax collector instructs the employer to restart it.

DCED also caps the total LST paid in a calendar year at $52, even when the employee works in several Pennsylvania municipalities. The primary place of employment determines which jurisdiction has first claim to the tax.

Philadelphia and Pittsburgh

Philadelphia operates outside the ordinary Act 32 withholding system. The Philadelphia Department of Revenue sets the Wage Tax at 3.735% for residents and 3.425% for nonresidents for pay dates from July 1, 2026 through June 30, 2027.

A Philadelphia employer withholds the Wage Tax from taxable compensation and files through the Philadelphia Tax Center. Employers withholding less than $350 a month pay quarterly, $350–$16,000 a month pay monthly, and employers at $16,000 or more move to semimonthly or weekly payments depending on the payroll schedule.

The City of Pittsburgh states that residents pay a 3% earned income tax, made up of 1% city tax and 2% school district tax. Non-Pennsylvania residents working in Pittsburgh pay 1% earned income tax.

The City of Pittsburgh charges employers a 0.55% Payroll Expense Tax on payroll expense generated by work performed in the city. A $900,000 annual Pittsburgh payroll produces $4,950 of Payroll Expense Tax before workers’ compensation and unemployment tax.

The City of Pittsburgh requires Payroll Expense Tax returns quarterly. The regular due dates are May 31, August 31, November 30, and February 28 for the preceding quarter.

Pittsburgh’s Local Services Tax is $52 per year and is collected from employees over the year. Pittsburgh applies the $12,000 low-income exemption and requires quarterly employer reports.

Minimum wage and overtime

Pennsylvania’s Minimum Wage Act guidance sets the minimum wage at $7.25 an hour and the tipped cash wage at $2.83. An employer can use the tip credit only where the employee receives more than $135 a month in tips and total pay reaches at least the full minimum wage.

Pennsylvania overtime guidance requires covered nonexempt employees to receive 1.5 times the regular rate after 40 hours in a workweek. Pennsylvania has no general daily-overtime rule, but the Prohibition of Excessive Overtime in Health Care Act limits mandatory overtime for certain health care workers.

Paydays and pay records

Pennsylvania’s Wage Payment and Collection Law requires employers to use regular paydays designated in advance. Wages earned in a pay period are due within the period set by a written employment contract, the customary lapse in the trade, or no later than 15 days after the pay period ends. Overtime may be paid with wages for the next pay period.

At hire, the employer has to tell employees the time and place of payment, rate of pay, and any fringe benefits or wage supplements, or post that information conspicuously at the workplace. Department of Labor & Industry wage guidance also requires the pay stub to show hours worked, rate of pay, gross wages, taxes and authorized deductions, and the beginning and ending dates of the pay period.

Final wages are due by the next regular payday after an employee quits, is laid off, or is discharged, according to the Department of Labor & Industry wage FAQs.

Workers’ compensation

Pennsylvania generally requires workers’ compensation coverage from the first employee. The Department of Labor & Industry applies the requirement to part-time and seasonal employees as well as full-time staff, subject to limited exclusions. Coverage can also follow work outside Pennsylvania when the employment is principally localized here or the contract of hire was made here under the state’s extraterritorial rules.

Employers can buy coverage from a licensed insurer, use the State Workers’ Insurance Fund, or apply to self-insure. Limited exclusions include certain agricultural and domestic workers, some casual employees, workers covered by other compensation systems, and employees with an approved religious exemption.

An uninsured employer can be required to reimburse the Uninsured Employers Guaranty Fund for benefits, costs, interest, penalties, and attorney fees. L&I’s employer guidance also states that each day without required coverage can support a criminal charge, with a potential $2,500 misdemeanor fine or $15,000 felony fine for an intentional violation.

Can you run Pennsylvania payroll yourself?

Yes, but Pennsylvania has more moving parts than a state with one statewide withholding rate and no municipal payroll taxes. State withholding and unemployment are straightforward. PSD codes, local EIT, Local Services Tax, and city-specific rules are the parts that create recurring administration.

Find payroll software that fits your business

PayGenie’s internal benchmark for payroll software is $6–$25 per employee per month. Full-service software can calculate and file state and local taxes, but the setup still depends on accurate home and work addresses and the right local tax collector accounts.

A payroll service fits when the main problem is keeping up with filings and local withholding. A PEO changes more of the arrangement because it adds co-employment, benefits administration, and workers’ compensation support while Pennsylvania keeps unemployment wages on the client account.

A 17-person machine shop in Pittsburgh

A 17-person precision machine shop in Pittsburgh has 12 production employees earning $52,000 a year, three supervisors at $72,000, and two office employees at $48,000. Annual payroll is $936,000, and every employee earns past the $10,000 UC wage base.

At the newly liable non-construction rate, Pennsylvania UC costs $382.20 per employee, or $6,497.40 across all 17. Pittsburgh’s 0.55% Payroll Expense Tax adds $5,148 on the $936,000 payroll.

Thirteen employees live in Pittsburgh, two live elsewhere in Pennsylvania, and two commute from West Virginia. Pittsburgh residents have 3% local earned income tax withheld. The West Virginia commuters can use Form REV-419 to stop Pennsylvania’s 3.07% state withholding when the reciprocal-state requirements are met, but because they work in Pittsburgh they remain subject to the city’s 1% nonresident earned income tax. The two Pennsylvania residents outside Pittsburgh use the higher of their resident EIT rate or Pittsburgh’s 1% nonresident work-location rate.

Each employee also contributes 0.07% to Pennsylvania UC on gross wages and, because all 17 earn above the local exemption threshold, Pittsburgh’s $52 Local Services Tax applies if this is their primary place of employment. Workers’ compensation pricing separates the production classifications from the office work even though both groups sit on the same payroll.

PEO rules specific to Pennsylvania

Pennsylvania’s Professional Employer Organization Act governs ongoing co-employment arrangements and applies regardless of whether a provider calls itself a PEO, staff leasing company, employee leasing company, or administrative employer. Temporary help arrangements and independent contractor relationships sit outside the Act.

What the agreement has to say

The professional employer agreement has to be in writing and signed by both parties. It allocates employer rights and duties and requires the PEO to pay covered employees and handle payroll-related withholding, reporting, and remittance required by the agreement and the Act.

Bonuses, commissions, severance, deferred compensation, profit sharing, and paid leave are outside the Act’s definition of wages unless the PEO expressly agrees to assume them. The agreement must also state how either side can terminate the relationship and identify any fees or costs payable on termination.

The PEO gives each covered employee written notice of the general nature of the co-employment relationship. Section 102 of Act 102 also defines the PEO administrative fee separately from wages, benefits, workers’ compensation, payroll taxes, withholding, and other assessments paid on behalf of covered employees.

What stays with the client

Unless the agreement expressly says otherwise, the client keeps the exclusive right to direct and control the work. Act 102 also leaves the client responsible for Pennsylvania wage and labor laws, and licensed professional work remains under the client’s direction for licensing and regulatory purposes.

Whose account reports unemployment wages

Pennsylvania keeps unemployment compensation at the client level. L&I’s professional employer arrangement guidance states that the client is the UC employer of leased workers, wages are reported on the client’s UC tax account, and contributions are paid at the client’s tax rate.

Section 304 of Act 102 lets the client authorize the PEO to file reports and pay contributions, interest, and penalties on the client’s behalf. The client account and experience rate stay in place, and the statute does not allow multiple employer reports on the same client account for one calendar quarter.

L&I tells a client using a PEO to add the PEO as a representative in UCMS. The authorization lets the PEO work on the account, while the client remains responsible for making sure its reporting requirements are met accurately.

Workers’ compensation and the client record

Section 303 of Act 102 requires the professional employer agreement to assign workers’ compensation responsibility to either the client or the PEO. If the PEO carries coverage, Pennsylvania permits multiple coordinated policies, an approved PEO self-insurance arrangement, or a master policy. Client-specific experience data and risk classifications still have to be reported separately.

At the client’s written request, the PEO must make available evidence of workers’ compensation coverage, loss history, and total wages paid for the client’s covered employees. The client remains responsible for direct-hire employees who are outside the PEO coverage.

If the PEO terminates the professional employer agreement, the workers’ compensation notice must explain when coverage will end. Under Section 303 of Act 102, termination by the insurer is effective at the earliest of 60 days after notice, 15 days after notice for nonpayment, or the date replacement coverage takes over.

Pennsylvania also sets reporting deadlines when the PEO provides workers’ compensation. Section 303 of Act 102 requires notice to L&I within 15 days after the professional employer agreement takes effect. The PEO has 10 days to report cancellation or termination of an agreement under which it assumed coverage, and 10 days to report a cancellation, termination, or change of workers’ compensation insurer.

Registration, filing, and deadlines

1. Register the business. Use myPATH and Pennsylvania employer registration guidance to establish state withholding and unemployment accounts. L&I uses the registration to determine UC liability and assign the employer account and rate.

Pennsylvania UC Tax Registration requires a new employer to register within 30 days after covered services are first performed. Late registration adds a 3% delinquency increase to the contribution rate and can carry an assessment of up to $10,000.

1. Set up local withholding. Use the DCED address lookup for each employee’s home and work address, keep the Residency Certification Form, and register with the appropriate local tax collector.
2. Report new hires. The 2026 Pennsylvania UC Employer’s Handbook requires new hires and employees returning after at least 30 days away to be reported within 20 days of hire.
3. File UC quarterly. Electronic reports and contributions are due April 30, July 31, October 31, and January 31 through UCMS.
4. File state withholding returns. The Department of Revenue requires every employer withholding account to file quarterly reconciliation returns, while deposits follow the quarterly, monthly, semimonthly, or semiweekly schedule assigned based on withholding volume.
5. File local returns. Act 32 employer instructions generally require EIT returns and remittances within 30 days after the quarter, with the W2-R annual reconciliation due by the last day of February. Philadelphia and Pittsburgh have separate city filing systems where applicable.

Pennsylvania payroll reference

Your unemployment rate

Pennsylvania issues Form UC-657, the Contribution Rate Notice, at the end of each calendar year. The notice shows the contribution rate for the coming year and the factors that make up the total rate.

For a 2026 notice mailed December 31, 2025, the regular appeal deadline was March 31, 2026. A notice mailed on another date carries its own deadline. Whoever prepares payroll needs the current notice because an experienced employer’s rate can change even when the $10,000 taxable wage base does not.

Rates and deadlines are current as of September 2026 and change annually. Verify against the linked source before filing.

Frequently asked questions

• How much should a payroll service cost in Pennsylvania?

  PayGenie’s internal benchmark for a payroll service is $20–$50 per employee per month. Payroll software runs $6–$25, and a PEO generally runs $40–$150 per employee per month or 3–12% of gross payroll. Pennsylvania quotes should be checked for local EIT, Local Services Tax, and Philadelphia or Pittsburgh filing because local-tax coverage varies by provider.

• What payroll taxes do employers pay in Pennsylvania?

  A newly liable non-construction employer pays 3.822% Pennsylvania UC on the first $10,000 of each employee’s wages in 2026. Employers also withhold 3.07% Pennsylvania income tax, 0.07% employee UC on gross wages, and applicable local EIT and Local Services Tax from employee pay. Workers’ compensation is a separate employer cost.

• Does Pennsylvania have local payroll taxes?

  Yes. Most Pennsylvania employers handle local earned income tax through Act 32 and use PSD codes based on the employee’s home and work addresses. Local Services Tax can add up to $52 per year. Philadelphia uses a separate Wage Tax, and Pittsburgh also imposes a 0.55% Payroll Expense Tax on employers.

• How does Pennsylvania local earned income tax withholding work?

  For an employee who lives and works in Pennsylvania, the employer compares the total resident EIT rate with the nonresident rate at the work location and withholds the higher rate. The employee’s Residency Certification Form and six-digit PSD codes identify the jurisdictions and tax collector.

• Does Pennsylvania require workers’ compensation for one employee?

  Generally, yes. Pennsylvania requires coverage when an employer has at least one employee who could be injured or develop a work-related disease in the state, subject to limited statutory exclusions. Coverage can come from a private carrier, the State Workers’ Insurance Fund, or approved self-insurance.

• Does a Pennsylvania PEO use its unemployment tax rate or mine?

  Pennsylvania uses the client’s unemployment compensation account and contribution rate. A PEO can be authorized to file the reports and make payments for the client, but the wages remain on the client account and the client remains the UC employer for covered workers.

• What is a PSD code in Pennsylvania?

  A PSD code is a six-digit number that identifies a Pennsylvania municipality for local earned income tax. Employees complete a Residency Certification Form at hire and after an address change so the employer can use the correct home and work PSD codes, tax rates, and collector.

• Does Pennsylvania have reciprocal tax agreements?

  Yes. Pennsylvania has reciprocal compensation agreements with Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia. A resident of one of those states can file Form REV-419 so Pennsylvania personal income tax is not withheld when the employer withholds the resident state’s income tax instead. Local earned income tax can still apply.

• What is the Philadelphia Wage Tax in 2026?

  For pay dates from July 1, 2026 through June 30, 2027, Philadelphia Wage Tax is 3.735% for residents and 3.425% for nonresidents. Employers withhold it from taxable compensation and file through the Philadelphia Tax Center.

• What is the Pittsburgh Payroll Expense Tax?

  Pittsburgh charges employers 0.55% of payroll expense tied to work performed in the city. The tax is employer-paid and filed quarterly. A $900,000 annual Pittsburgh payroll produces $4,950 of Payroll Expense Tax.

• How often do I file Pennsylvania unemployment reports?

  Pennsylvania UC wage and tax reports are filed quarterly through UCMS. Regular due dates are April 30, July 31, October 31, and January 31 for the preceding quarter.

• How often do employees have to be paid in Pennsylvania?

  Pennsylvania requires regular paydays designated in advance. Under the Wage Payment and Collection Law, wages are due within the period set by a written employment contract, the customary timing for the trade, or no later than 15 days after the pay period ends. Final wages are due by the next regular payday.
