Pennsylvania has a refreshingly simple state income tax — one flat rate, no brackets, no confusion. But the moment you hire your first employee and discover you need to register with over 2,600 possible local tax jurisdictions, "simple" stops being the right word. Here's everything you need to run PA payroll correctly in 2026.
- PA state income tax: flat 3.07% on all wages — no brackets, no exemptions
- PA SUI (employer-paid): taxable wage base of $10,000; new employer rate approximately 3.8% (experience-rated employers vary)
- Local EIT: required in nearly every PA municipality — rates typically 1% to 3.75%; employer withholds based on work location
- No state SDI: Pennsylvania has no state disability insurance program — nothing to withhold
- PA-4 form: PA's equivalent of the federal W-4; collect one from every new hire
Pennsylvania State Payroll Taxes: What Employers Must Withhold
There are three state-level tax obligations every PA employer needs to understand. Federal taxes (FICA, FUTA) layer on top — this article covers what's specific to Pennsylvania.
| Tax | Rate (2026) | Who Pays | Wage Base |
|---|---|---|---|
| PA Personal Income Tax (PIT) | 3.07% flat | Employee (employer withholds) | All wages |
| PA SUI / SUTA | ~3.8% new employer; varies for experienced | Employer only | $10,000 per employee |
| Local EIT | 1% to 3.75% (varies by municipality) | Employee (employer withholds) | All earned income |
The PA Personal Income Tax has been locked at 3.07% since 2004 — one of the most stable tax rates in the country. No brackets, no complicated calculations. Multiply gross wages by 0.0307 and you're done.
PA SUI is employer-paid and experience-rated after your first few years in business. New employers use a standard rate (approximately 3.8% as of recent years — confirm your assigned rate with the PA Office of Unemployment Compensation, as it's set annually). The $10,000 wage base is per employee per calendar year, so SUI costs stop once each worker crosses that threshold.
Pennsylvania Local Earned Income Tax (EIT): The Tricky Part
"PA payroll isn't hard — it's the local layer that catches small businesses off guard. Get that right from day one and the rest is straightforward."
This is the part most out-of-state business owners don't see coming. Pennsylvania is unusual: nearly every municipality levies its own earned income tax on top of the state rate. Over 2,600 taxing jurisdictions.
Pennsylvania has more local earned income tax jurisdictions than almost any other US state — making it one of the most complex payroll environments in the country. The good news: once you've identified your correct local tax collector, the ongoing process is routine.
The core rule: withhold local EIT based on where the employee works, not where they live. If your employee works at your Allentown shop but lives in a neighboring township with a higher rate, they may owe the difference when they file — but your obligation is to withhold based on the work location.
Rates typically run from 1% to about 2%, but Philadelphia is the outlier at up to 3.75% for residents. Philadelphia employers also face additional city-specific taxes (BIRT and NPT) — if you're operating in Philly, get a local accountant involved for the initial setup.
You don't remit local EIT to the state — you remit to the correct local tax collector for your work location. The three major collectors are Berkheimer, Keystone Collections Group, and Jordan Tax Service, but your specific municipality may use a different one. Use the PA Department of Community & Economic Development (DCED) Act 32 Local Tax Collector lookup tool to find the right collector and rate for every work location. Take David, a plumbing company owner in Bucks County (a composite of clients we see), who had employees working across three different townships — each had its own collector and rate. Fifteen minutes with the DCED lookup tool, three registrations, and it was sorted.
PA Payroll Compliance Checklist for Small Businesses
Get these seven steps done before your first paycheck and you won't have to scramble later.
- 1 Register with the PA Department of Revenue for a state employer withholding account (myPATH portal).
- 2 Register with the PA Office of Unemployment Compensation (UC Management System) for SUI.
- 3 Identify your local EIT collector using the DCED Act 32 lookup tool — do this for every work location, not just your main office.
- 4 Collect a PA-4 form from every new employee (Pennsylvania's withholding certificate — similar to the federal W-4 but state-specific).
- 5 Withhold 3.07% state PIT plus the correct local EIT rate from every paycheck.
- 6 Remit on schedule — the PA Department of Revenue assigns your filing frequency (monthly or quarterly) based on withholding volume. Late deposits carry penalties.
- 7 Issue pay stubs showing all withholdings — state PIT, local EIT, and SUI (employer portion). Clear pay stubs protect you and keep employees informed.
Pennsylvania payroll comes down to three numbers: 3.07% state income tax (flat, no exceptions), your SUI rate on the first $10,000 per employee, and the local EIT rate for your work location. The local layer takes a one-time setup effort — after that, running PA payroll is routine. Register correctly, withhold accurately, issue compliant pay stubs, and you're covered.
Frequently Asked Questions
What is the Pennsylvania state income tax rate for 2026?
Pennsylvania has a flat state income tax rate of 3.07% on all wages. No brackets, no tiered rates — every employee pays the same percentage regardless of income level. Employers withhold 3.07% from every paycheck and remit to the PA Department of Revenue.
Do I have to withhold local earned income tax (EIT) for my Pennsylvania employees?
Yes — and this applies to nearly all PA employers. You withhold local EIT based on where the employee works, not where they live. Rates vary by municipality, typically between 1% and 3.75%. You must register with and remit to the correct local tax collector for your specific work location, which you can find via the DCED Act 32 lookup tool.
Does Pennsylvania have state disability insurance (SDI)?
No. Pennsylvania has no state disability insurance program or paid family leave tax, so there's no SDI withholding from employee paychecks. This simplifies payroll compared to states like California or New Jersey, which both levy mandatory SDI contributions.
What is the PA-4 form and do I need it?
The PA-4 is Pennsylvania's employee withholding certificate — the state equivalent of the federal W-4. Collect a completed PA-4 from every new hire before their first paycheck. Unlike the federal W-4, it's a simple one-page document that reflects the flat-rate structure.
What happens if I withhold the wrong local EIT rate?
Under-withholding means your employee will owe the difference at tax time — and potentially face penalties. If the error is yours (wrong municipality identified), you may face liability for the shortfall plus interest. Fix it quickly: contact the correct local tax collector, correct future withholdings, and issue a corrected W-2 if the error spans a full year.

Generate Pennsylvania-Compliant Pay Stubs FreeBottom Line
Pennsylvania payroll is more manageable than most states — a flat 3.07% income tax, no SDI, and straightforward SUI rates — but the local EIT layer is where employers get tripped up. Work location, not residence, determines which municipality gets the tax, and rates can swing from near zero to 3.75%.
Get the municipality right, collect your PA-4s on day one, and document every deduction on each pay stub. Do those three things and you'll stay compliant without needing a dedicated payroll department.
