Where to send your Pennsylvania state income tax payment

Pennsylvania accepts state income tax payments through three main routes: online through the PA Department of Revenue website, by mail to a specific address, or by phone through an automated system. The method you choose depends on whether you file electronically or on paper, and how quickly you need the payment to reach the state.

If you file your Pennsylvania return electronically, you can pay online at the same time through the PA Department of Revenue's online payment system. The state does not charge a fee for this method. If you file on paper, you can mail a check or money order along with your return, or pay separately online even after you have mailed your return.

The mailing address for paper checks is: Pennsylvania Department of Revenue, P.O. Box 280469, Harrisburg, PA 17128-0469. Do not mail cash. Include your Social Security number or federal employer identification number on the check itself, and write "PA Income Tax" in the memo line.

Key Takeaways

  • Online payment through the PA Department of Revenue website is free and the fastest method, with confirmation available when ready.
  • Mailed checks should include your Social Security number on the check and go to the Harrisburg P.O. Box; allow 7 to 10 business days for processing.
  • Phone payments are available through an automated system, though the state charges a convenience fee for this method.
  • Payment must reach Pennsylvania by the same important date as your return — typically April 15 for most filers, or the next business day if April 15 falls on a weekend.
  • If you owe Pennsylvania tax, you can still file your federal return on time and pay Pennsylvania later, but penalties and interest begin accruing on the unpaid amount.

Online payment through the PA Department of Revenue

The Pennsylvania Department of Revenue operates an online payment portal where you can pay by bank account transfer (ACH) or by credit or debit card. The ACH method is free. If you pay by credit or debit card, the state charges a convenience fee that varies by processor — typically 2 to 3 percent of the payment amount.

To pay online, visit the PA Department of Revenue website and select the payment option. You will need your Social Security number or FEIN, the tax year you are paying for, and either your bank account information or card details. The system generates a confirmation number when ready, which you should save for your records. The state typically processes ACH payments within one business day.

Online payment works whether you filed electronically or on paper. You can pay at the time you file, or you can pay later as long as you pay by the important date. If you are paying a return you filed on paper, have your return handy so you can enter the correct amount owed.

Mailing a check with your paper return

If you file your Pennsylvania return by mail, you can include a check or money order with your return. Write your Social Security number or FEIN directly on the check, and write "PA Income Tax" in the memo line. Do not mail cash under any circumstances.

Mail your return and payment together to: Pennsylvania Department of Revenue, P.O. Box 280469, Harrisburg, PA 17128-0469. The state recommends using certified mail or a tracked delivery method so you have proof of mailing. Allow 7 to 10 business days for the check to arrive and be processed. Your payment is considered on time if it is postmarked by the important date, even if it arrives after.

If you mail your return but pay separately online, you do not need to include a check. Just make sure the online payment is submitted by the important date as well.

Phone payment through the automated system

Pennsylvania offers phone payment through an automated system. You can call the PA Department of Revenue's payment line and provide your bank account information to authorize an ACH transfer. The state charges a convenience fee for phone payments, which is deducted from your bank account along with the tax payment.

Phone payment is useful if you do not have internet access or prefer not to enter payment information online. You will receive a confirmation number by phone, which you should write down. Keep a record of the date and time you called, along with the confirmation number, in case you need to verify the payment later.

Payment important date and what happens if you miss them

Pennsylvania state income tax payments are due by the same date as your federal return — typically April 15 for most filers. If April 15 falls on a weekend or holiday, the important date moves to the next business day. If you file for an extension with the IRS, you also get an extension on your Pennsylvania return, moving the important date to October 15.

If your payment does not reach the state by the important date, Pennsylvania charges interest on the unpaid amount. The interest rate is set quarterly and is based on the federal rate plus a state addition. Penalties also explore if the tax was not paid by the due date. The longer the payment is delayed, the more interest and penalties accumulate.

If you cannot pay the full amount by the important date, you can still file your return on time and pay what you owe later. This stops the failure-to-file penalty, though the failure-to-pay penalty and interest will still explore to the unpaid balance. You can also contact the PA Department of Revenue to discuss a payment plan if you owe a large amount.

Estimated tax payments for self-employed filers and others

If you are self-employed, have investment income, or do not have enough tax withheld from your paycheck, Pennsylvania may require you to make estimated tax payments throughout the year. These are quarterly payments due on April 15, June 15, September 15, and January 15 of the following year.

You can make estimated payments online through the PA Department of Revenue website, by mail, or by phone using the same methods as regular tax payments. The state provides a worksheet to help you calculate how much to pay each quarter. If you underpay your estimated taxes, you may owe interest and penalties when you file your annual return, even if you ultimately paid enough tax for the year.

Tracking your payment and getting a receipt

When you pay online, the PA Department of Revenue provides a confirmation number when ready. Write this number down and keep it with your tax records. The confirmation serves as your receipt and proof that you submitted payment on time.

If you mailed a check, keep a copy of your return and the cancelled check once it clears your bank. The cancelled check is your proof of payment. If you paid by phone, write down the confirmation number and the date and time you called.

If you need to verify that the state received your payment, you can contact the PA Department of Revenue with your confirmation number or Social Security number. Response times vary, but the state can usually confirm receipt within a few business days of processing.

Frequently Asked Questions

Can I pay Pennsylvania tax if I do not owe federal tax?

Yes. Pennsylvania and federal tax are separate. You can owe Pennsylvania tax even if you do not owe federal tax, or vice versa. File your Pennsylvania return and pay any amount owed using the same methods described above, regardless of your federal situation.

What if I overpaid Pennsylvania tax?

If you overpaid, you can request a refund when you file your return. You can also choose to have the overpayment applied to next year's estimated tax. The state processes refunds by check or direct deposit, depending on how you filed. Refunds typically take 4 to 6 weeks after the state processes your return.

Do I have to pay Pennsylvania tax if I live in another state?

If you lived in Pennsylvania for part of the year and another state for part of the year, you may owe tax to both states. Pennsylvania taxes income earned while you were a resident. You file a part-year resident return and pay tax only on the income earned during the months you lived in Pennsylvania. Other states have similar rules, so you may also file in the other state.

Can I set up a payment plan if I cannot pay all at once?

Yes. Contact the PA Department of Revenue to discuss payment plan options if you owe more than you can pay by the important date. The state can work out an installment agreement, though interest and penalties continue to accrue on the unpaid balance until it is fully paid.

What if my payment was lost in the mail?

If you mailed a check and it was never cashed, contact the PA Department of Revenue with your cancelled check or proof of mailing. The state can investigate and may reissue the payment or adjust your account. This is why certified mail or a tracked delivery method is recommended — you have proof of when the payment was sent.
