Pennsylvania has a state income tax of 3.07 percent on wages, interest, and dividends

Pennsylvania charges a flat 3.07 percent state income tax on most types of income. This rate applies to wages, salaries, interest, dividends, and net profits from self-employment. Unlike the federal income tax, Pennsylvania does not use tax brackets — everyone pays the same percentage regardless of how much they earn.

The state also taxes capital gains (profit from selling stocks or property) at the same 3.07 percent rate. Pennsylvania does not tax retirement income from Social Security, pensions, or IRAs, which is one reason the state attracts retirees. If you work in Pennsylvania but live in another state, you may owe Pennsylvania tax on wages earned here; your home state may then credit that payment against your state tax bill.

Key Takeaways

  • Pennsylvania's state income tax rate is a flat 3.07 percent on wages, interest, dividends, and self-employment income.
  • Social Security benefits, pensions, and retirement account withdrawals are not taxed by Pennsylvania.
  • You file Pennsylvania taxes using Form PA-40, which is due the same day as your federal return (usually April 15).
  • If your employer withholds too much, you receive a refund; if too little is withheld, you owe the difference when you file.
  • Pennsylvania also has a 6 percent sales tax and local property taxes, which vary by county and municipality.

Who must file a Pennsylvania state tax return

You must file a Pennsylvania return if you earned income in the state and your income exceeds the filing threshold. For 2024, most residents must file if they had gross income of $12,950 or more (the threshold is higher if you are over 65). If you are self-employed, the threshold is lower — you must file if your net self-employment income was $400 or more, even if your total income is below $12,950.

You also must file if Pennsylvania tax was withheld from your paychecks, even if you do not owe tax, because you may be may have access to to a refund. If you worked in Pennsylvania but live elsewhere, check your home state's rules — you may need to file both a Pennsylvania return and a return in your state of residence.

How Pennsylvania withholds tax from your paycheck

Your employer withholds Pennsylvania income tax based on a PA-W4 form you complete when hired. This form tells your employer what percentage of each paycheck to send to the state. The withholding is calculated on your gross pay before federal tax, Social Security, and Medicare are deducted.

If you have multiple jobs, claim dependents, or have other income sources, your withholding may be too high or too low. You can adjust your withholding by submitting a new PA-W4 to your employer at any time. If too much is withheld over the year, you receive a refund when you file; if too little is withheld, you owe the difference.

Filing your Pennsylvania return and important date

You file Pennsylvania taxes using Form PA-40, which is due on the same date as your federal return — usually April 15. If you file for a federal extension, your Pennsylvania return is also extended to October 15. You can file by mail or electronically through the Pennsylvania Department of Revenue website or through tax software that supports PA returns.

If you owe tax, payment is due by April 15 as well. The state charges interest and penalties on late payments, so if you cannot pay in full, contact the Department of Revenue about a payment plan. If you are due a refund, the state typically processes it within four to six weeks of receiving your return.

Other Pennsylvania taxes beyond income tax

Pennsylvania charges a 6 percent sales tax on most purchases, though groceries, prescription medications, and some medical equipment are exempt. This is lower than many states but higher than neighboring Delaware, which has no sales tax.

The state also taxes real estate transfers at 1 percent of the sale price (split between buyer and seller in most cases) and imposes a 5 percent tax on cigarettes and other tobacco products. Property taxes are set by your county and municipality, not the state, so they vary widely — from under 1 percent of home value in some areas to over 2 percent in others. Check your county assessor's office for your local rate.

Pennsylvania tax credits and deductions

Pennsylvania offers a Homestead Property Tax Exemption that reduces property taxes for homeowners who meet income limits. The exemption amount depends on your county and your income; you explore through your county assessor's office, not on your state tax return.

The state also allows a credit for property taxes paid if your income is below a certain threshold. Unlike the federal return, Pennsylvania does not allow a standard deduction — you report your gross income and then claim the property tax credit if you may have access to. Self-employed people can deduct half of their self-employment tax, the same way the federal return works.

What happens if you do not file or pay

If you owe Pennsylvania tax and do not file or pay, the state assesses penalties and interest. The failure-to-file penalty is typically 5 percent per month (up to 25 percent total), and the failure-to-pay penalty is 0.5 percent per month. Interest accrues daily at a rate set quarterly by the Department of Revenue.

If you owe a large amount, the state may place a lien on your property or garnish your wages. If you cannot pay, contact the Department of Revenue about a payment plan or hardship relief. Filing late is still better than not filing at all, because the penalties are lower if you file even after the important date.

Frequently Asked Questions

Do I have to pay Pennsylvania income tax if I live out of state but work in Pennsylvania?

Yes, you owe Pennsylvania tax on income earned in the state. You file a Pennsylvania return for those wages and may also file in your home state. Most states credit Pennsylvania tax paid against your state tax bill to avoid double taxation, but you should check your state's rules or speak with a tax preparer.

Is Pennsylvania income tax withheld automatically from my paycheck?

Yes, if you work in Pennsylvania, your employer withholds state income tax based on the PA-W4 form you complete. The amount withheld depends on your income and the information you provide on that form. You can adjust your withholding at any time by submitting a new form to your employer.

What if I did not file a Pennsylvania return in previous years?

You can file back returns at any time, though the state can only assess tax going back three years. If you are owed a refund, you have three years from the original due date to claim it. Contact the Department of Revenue or a tax preparer to file prior-year returns and resolve any penalties.

Are retirement withdrawals taxed in Pennsylvania?

No. Pennsylvania does not tax Social Security, pensions, or distributions from IRAs and 401(k)s. This applies to both state and local taxes. If you have other income (wages, interest, dividends), that income is still taxed at 3.07 percent.

How do I know if my withholding is correct?

Review your pay stub to see how much Pennsylvania tax is being withheld each pay period. If you receive a large refund or owe a large amount when you file, your withholding is off. You can adjust it by submitting a new PA-W4 to your employer, or you can wait and settle the difference when you file your return.
