To pay sales tax in PA, file the PA-3 return and remit payment through myPATH, the Department of Revenue’s online portal, by the 20th of the month after each reporting period ends. The state rate is 6%, plus 2% in Philadelphia and 1% in Allegheny County. Your filing frequency (monthly, quarterly, or semi-annual) is assigned by the Department based on how much tax you report, and a return is required for every period even if you had no taxable sales.
Register Before Your First Sale
You need a Pennsylvania sales tax license before collecting any tax. Registration is free through the Pennsylvania Online Business Tax Registration on myPATH, which replaced the older E-TIDES system in late 2022.1Commonwealth of Pennsylvania. Register My Business for Taxes The same application covers sales, use, and hotel occupancy tax. Once processed, you’ll receive a Pennsylvania Tax ID number and your license, usually within a few weeks. Creating a myPATH login at the same time makes filing easier later.
How Often You File
The Department sets your filing frequency by looking at the tax you reported in the third quarter (July through September) and applying the result to the next calendar year:2Pennsylvania Department of Revenue. How Is My Filing Period for Sales Tax Determined
- Monthly if you reported $600 or more in Q3
- Quarterly if you reported between $75 and $599.99
- Semi-annual if you reported less than $75
Whatever your frequency, returns are due by the 20th of the month after the period ends. A monthly filer’s January return is due February 20. A quarterly filer’s January-through-March return is due April 20. When the 20th lands on a weekend or holiday, the deadline shifts to the next business day.3PA.gov. 2026 Pennsylvania Sales, Use, and Hotel Occupancy Tax Returns, Tax Periods, and Administrative Due Dates REV-819
A quiet period doesn’t excuse you. If you had zero taxable sales, you still owe a zero return; skipping it counts as a compliance failure.
What Goes on the PA-3
The return walks you through the calculation in order. Start with total gross sales for the period, including any exempt transactions. Then subtract exempt sales to arrive at net taxable sales. Apply the 6% state rate plus 2% for Philadelphia sales or 1% for Allegheny County sales, based on where the buyer takes possession of the goods rather than where your business sits.4Department of Revenue. Sales, Use and Hotel Occupancy Tax – Section: Overview
Use tax gets reported on the same PA-3. If you bought taxable goods or services for your business and the seller didn’t charge Pennsylvania sales tax (a common issue with out-of-state vendors), you owe use tax at the same 6% rate plus any local rate.5Commonwealth of Pennsylvania. Use Tax The same applies if you pull an item from resale inventory and use it in your own operations; use tax is owed on that item’s purchase price.
One trap catches retailers off guard. If a customer never pays and you’ve already remitted sales tax on that sale, you cannot deduct the bad debt on your PA-3. You have to file a separate petition for refund with the Department, and the debt must be written off in your books and claimed as a bad debt deduction on your federal return.6Pennsylvania General Assembly.

Paying Through myPATH
MyPATH is the main portal for filing and payment. The system takes your return data and calculates the vendor discount automatically. If you prefer phone filing, TeleFile is available at 1-800-748-8299, and you’ll need your eight-digit Account ID, your FEIN or SSN, and the period ending date.4Department of Revenue. Sales, Use and Hotel Occupancy Tax – Section: Overview
Payment options through myPATH include:
- ACH debit, where you authorize the Department to pull funds from your bank account
- ACH credit, where you instruct your bank to push funds to the state
- Credit card, processed through a third party that charges a convenience fee
Paper filers approved to do so can mail a check or money order payable to the Commonwealth of Pennsylvania with the PA-3. Electronic filing is faster and gives you immediate confirmation, which matters most when you’re filing close to the deadline.
The Vendor Discount for On-Time Filing
Pennsylvania gives on-time filers a small discount for handling collection. When you file and pay by the deadline, myPATH and TeleFile calculate it automatically on Line 4:7Pennsylvania Department of Revenue. What Is the Latest Date and Time a Sales and Use Tax Return and Payment Can Be Submitted
- Monthly filers: 1% of tax due or $25, whichever is less
- Quarterly filers: 1% of tax due or $75, whichever is less
- Semi-annual filers: 1% of tax due or $150, whichever is less
The return and payment must be submitted by 11:59 PM on the due date to qualify. One day late and the discount is gone.
Accelerated Prepayments for Large Filers
Businesses that remit substantial sales tax owe accelerated prepayments on top of their monthly returns. The requirement is triggered by your actual tax liability during the third quarter of the prior year:8Commonwealth of Pennsylvania. Accelerated Sales Tax AST Prepayments
- AST Level 1 ($25,000 to $99,999 in Q3 liability): prepay 50% of either the current month’s actual liability or the same month from the prior year
- AST Level 2 ($100,000 or more in Q3 liability): prepay 50% of the same month’s liability from the prior year, with no alternate calculation
Prepayments are due by the 20th of the current month; the full return for that period is due by the 20th of the following month. Missing a prepayment carries the same penalties and interest as any other missed deadline.
Penalties and Interest If You File Late
Late filing gets expensive fast. Pennsylvania charges a 5% penalty on the unpaid tax for the first month a return is late, and another 5% for each additional month or partial month, up to 25%. The minimum penalty is $5, no matter how small the balance.9Pennsylvania Bulletin. Pennsylvania Code 61 121.26 – Penalties for Failure to File or for Filing a Late Return
Daily interest runs on top of the penalty. For 2025 and 2026, the annual rate is 7%, applied daily at 0.000192. Multiply the unpaid tax by the number of days late, then by 0.000192.10PA Department of Revenue. 2026 Interest Rate and Calculation Method for Title 72 Taxes Due After Jan 1 1982 REV-1611
A vendor who owes $5,000 and files three months late faces a $750 penalty (15%) plus roughly $90 in interest, close to $850 in avoidable cost. The Department can waive the penalty if you show reasonable cause and no willful neglect, but forgetting doesn’t clear that bar. Interest is never waived.
