Pennsylvania Income Tax: A Plain-English Guide

Last updated May 18, 2026

·Independent Pennsylvania tax education

Pennsylvania has a flat personal income tax that catches almost anyone earning income in the state. This guide covers who files, the current rate, deductions and credits, and how to file the PA-40.

Key takeaways

Pennsylvania has a flat personal income tax that applies to most residents and most income earned in PA.
Almost everyone who earns wages, self-employment income, or rental income in PA needs to file a PA-40.
Pennsylvania does not allow most federal deductions but does have several PA-specific credits.
Most filers can file the PA-40 online through myPATH for free.

Pennsylvania income tax at a glance

Pennsylvania charges a flat percentage on most personal income. It does not use brackets the way the federal system does. The return is called the PA-40 and is filed once a year, generally on the same April deadline as the federal Form 1040.

On top of state income tax, most workers also pay a separate local earned income tax (EIT) set by their municipality and school district. The PA-40 does not cover local EIT.

Who has to file a PA-40

You generally have to file a Pennsylvania PA-40 if any of the following is true:

You were a PA resident and earned more than the PA filing threshold.
You were a part-year PA resident with PA-source income.
You were a non-resident with PA-source income (wages earned in PA, PA rental property, PA business income).
You owe Pennsylvania use tax on out-of-state purchases.
You want a refund of PA tax withheld.

Even if no PA tax is owed, you usually still need to file to get a refund of any withholding. The PA Department of Revenue does not send refunds automatically without a return.

The flat PA income tax rate

Pennsylvania's personal income tax rate is set by statute and has been a flat percentage of taxable compensation, net profits, and certain other income classes for many years. Because rates can change with new budgets, always confirm the current rate on the PA Department of Revenue before you file.

What PA taxes (and what it does not)

Pennsylvania taxes eight classes of income, including:

Compensation (wages, salaries, tips).
Net profits from a business or profession.
Net gains from the sale of property.
Net gains or income from rents, royalties, patents, and copyrights.
Dividends.
Interest.
Gambling and lottery winnings (with state-specific rules).
Income from estates or trusts.

Pennsylvania generally does not tax Social Security benefits or qualified employer-sponsored retirement income for people who have reached retirement age. Distributions taken before retirement age can be treated differently. Confirm your situation with the PA Department of Revenue or a qualified PA preparer.

Deductions and credits

Pennsylvania does not offer a standard deduction or personal exemption. Instead, several PA-specific credits and programs lower what you owe:

Tax Forgiveness (Schedule SP). Reduces or eliminates PA tax for lower-income households based on eligibility income.
Credit for Taxes Paid to Other States. If you live in PA but earned income in another state with its own income tax, you may avoid double taxation.
Education tax credits (where available). Some PA-administered programs offer credits to businesses or families, subject to caps and eligibility.

How to file your PA-40

Most filers have three practical options for filing the PA-40:

myPATH, the PA Department of Revenue's free online portal. Most filers can file electronically and get faster refunds.
Commercial tax software that supports Pennsylvania returns. Many federal tax products bundle PA support.
A licensed preparer like a Pennsylvania CPA, enrolled agent, or tax attorney. Useful for complicated PA returns, multistate filings, or audits. See our guide to finding a PA tax professional.

Paying what you owe

If you owe PA tax with your return, you can pay through myPATH using electronic funds withdrawal, debit/credit card, or mailed check. If you can't pay the full balance, the Department of Revenue offers payment plan options.

Self-employed Pennsylvanians and many landlords are also expected to make quarterly estimated payments. See our Pennsylvania tax deadlines page for the estimated payment calendar.

Best practices

Confirm the current PA flat tax rate at the PA Department of Revenue website each year before you file.
Track every W-2, 1099, and rental statement so your PA-40 matches what employers and payers reported.
Save proof of estimated payments and PA tax withheld in case the Department of Revenue contests them later.
Check Schedule SP for tax forgiveness eligibility if your household income is lower.
File electronically through myPATH for faster refunds and fewer math errors.

Common mistakes

Treating PA the same as a federal return and trying to claim the federal standard deduction.
Missing the local earned income tax (EIT) filing entirely, which is separate from the state PA-40.
Forgetting Schedule SP (tax forgiveness) when household income would qualify.
Letting an employer's incorrect PA withholding go uncorrected.
Filing late and assuming there is no penalty because no PA tax is owed.

Frequently asked questions

Is Pennsylvania income tax really a flat rate?

Yes. Unlike many states, Pennsylvania charges a single flat percentage on taxable personal income. There are no income brackets. Local earned income tax is separate and varies by municipality.

Do I need to file a PA-40 if I had no PA tax withheld?

Often yes. The withholding question and the filing question are different. If you earned PA-taxable income above the filing threshold, you generally need to file even if no PA tax was withheld.

Does Pennsylvania tax Social Security or retirement income?

Pennsylvania generally does not tax Social Security benefits, and qualified retirement income from a former employer is often excluded. Distributions taken before retirement age can be treated differently. Always confirm with the PA Department of Revenue or a qualified preparer.

Is there a Pennsylvania standard deduction?

No. Pennsylvania does not offer a standard deduction or personal exemption the way the federal return does. Instead, PA has tax forgiveness for lower-income households (Schedule SP).

Where can I file my PA-40 for free?

Most filers can file the PA-40 online through myPATH, the PA Department of Revenue's free portal. Some commercial tax software also supports PA returns.
