How to File Pennsylvania Sales Tax Online in 2026

How to file Pennsylvania sales tax in myPATH: filing frequency, due dates on the 20th, AST prepayments, zero returns, EFT rules, discount, penalties.

How to File Sales Tax Online in Pennsylvania

Pennsylvania sales, use, and hotel occupancy tax returns are filed online in myPATH (my Pennsylvania Tax Hub), the Department of Revenue's free online tax system, on the Sales, Use, and Hotel Occupancy Tax Return. Monthly and quarterly returns are due on the 20th of the month after the period, semiannual returns are due August 20 and February 20, and a return is required every period, even when no taxable transactions occur.

This guide covers who files and how often, what the return asks for, how Allegheny County and Philadelphia local tax fits in, due dates for 2026, prepayment rules for larger businesses, how to pay, the vendor discount, and what late filing costs.

This article is educational information, not tax advice. Filing rules, thresholds, and penalties can change, so confirm current requirements with the Pennsylvania Department of Revenue before you file.

Pennsylvania sales tax filing at a glance

  • Who administers it: Pennsylvania Department of Revenue.
  • Online portal: myPATH at mypath.pa.gov. Approved third-party software and TeleFile (by approval only) are the other options.
  • Return: Sales, Use, and Hotel Occupancy Tax Return (PA-3). The Department says PA-3 forms are not available for download from the internet.
  • Filing frequency: Monthly (with prepayments for larger filers), quarterly, or semiannual, based on your tax liability. New filers are set up as quarterly filers.
  • Due dates: The 20th of the month after the period. Semiannual returns are due August 20 and February 20. If the 20th falls on a weekend or holiday, the report and payment are due the next business day.
  • Zero returns: Required for every period, whether or not taxable transactions occurred.
  • Payment: ACH debit, ACH credit, or credit card. Payments of $1,000 or more must be made electronically.
  • Economic nexus: More than $100,000 in annual Pennsylvania gross sales, measured by calendar year.
  • Vendor discount: For timely returns and payments, the lesser of 1% of tax collected or $25 (monthly), $75 (quarterly), or $150 (semiannual).

Who has to file, and how often

Every business holding a Pennsylvania sales tax license files a return for each assigned period. The Department says a business with property or inventory in Pennsylvania must collect the tax on direct sales to Pennsylvania customers. Sellers with no physical presence have economic presence, and must register and collect, when their Pennsylvania gross sales exceed $100,000. The Department measures that threshold by calendar year, counts taxable and nontaxable sales on all channels, and applies no transaction count. After the first year, collection begins in the second quarter (April 1) to give sellers time to compile the prior calendar year's sales. Marketplace sellers count only direct sales and sales through facilitators that do not collect the tax for them. See our Pennsylvania sales tax guide for registration details. Selling software? Our post on Pennsylvania SaaS sales tax explains how it is treated there.

The Department's guide to starting a business says new sales tax filers are set up as quarterly filers. Each year the Department reviews every filer's frequency and, if it changes, notifies the business in writing. The frequency levels in the Retailer's Information guide (REV-717) are:

Filing frequencyActual tax liabilityDue date
Monthly with prepayments (AST)$25,000 or more per quarterPrepayment by the 20th of the current month; return by the 20th of the following month
MonthlyMore than $600 per quarter, but less than $25,00020th of the following month
QuarterlyLess than $600 per quarter, but more than $300 annually20th of the month after the quarter
Semiannual$300 or less annuallyAugust 20 (January to June) and February 20 (July to December)

Another Department publication describes the quarterly cutoff by third-quarter liability, so confirm the frequency assigned to your own account in myPATH.

Accelerated sales tax (AST) prepayments

Larger businesses make prepayments on top of their monthly returns. The level depends on your actual tax liability for the third calendar quarter of the preceding year:

  • AST Level 1 ($25,000 to less than $100,000): Prepay 50% of your tax liability for the same month of the previous year, or at least 50% of the actual liability for the current period.
  • AST Level 2 ($100,000 or more): Prepay 50% of your tax liability for the same month of the previous year. The alternate calculation is not available.

Prepayments are due by the 20th of the current month, and the return for the period is due by the 20th of the following month. The Department says the current month's prepayment and the prior month's remaining liability must be separate payments.

Before you start: set up myPATH

  1. Register in myPATH at mypath.pa.gov. The Department says sales tax license registration is completed through the Pennsylvania Online Business Tax Registration in myPATH, and returns are filed under the 8-digit sales tax account ID it assigns. Our sales tax permit overview explains the process. myPATH is free and available 24 hours a day, and some features are available without creating a username and password, while others require an account.
  2. Gather your numbers for the period. The Department's TeleFile page lists the figures the return asks for: Pennsylvania gross sales, rentals, and services; net taxable sales, rentals, and services; use tax due; any E-911 fee; applicable credits; and the corresponding sales tax amounts for Philadelphia and Allegheny County, if applicable.

Step-by-step: filing a Pennsylvania sales tax return in myPATH

The Department does not publish a screen-by-screen walkthrough for the sales tax return, so these steps follow the information the return asks for.

  1. Log in to myPATH and open your sales, use, and hotel occupancy tax account for the period you are filing.
  2. Report gross sales. Enter total Pennsylvania gross sales, rentals, and services for the period.
  3. Report net taxable sales. Enter taxable sales, rentals, and services after exempt and resale transactions. See the Pennsylvania resale certificate rules for what to collect from buyers.
  4. Report use tax. All licensees report use tax on taxable purchases they did not pay tax on through this same return, with the first return filed after the first taxable use. The Department says use tax is reported on line 6 of the return and that no discount applies to it.
  5. Report local tax. Enter the corresponding Philadelphia and Allegheny County amounts if you have sales there.
  6. Add fees and credits. Enter any prepaid wireless E-911 surcharge, which has its own line on the return, and any applicable credits.
  7. Pay and submit. Pay electronically and save the confirmation.

Local tax and rate pitfalls

The Department states that the Pennsylvania sales tax rate is 6%. By law, a 1% local tax is added to purchases in Allegheny County and a 2% local tax is added to purchases in Philadelphia. All three taxes are reported on the same return under the same sales tax account ID. Per the Department, only Allegheny County and Philadelphia have imposed local taxes.

The local tax applies only to sales originating in, or property or services used in, the county or city that imposed it. Sales of property delivered to an out-of-state location are not subject to the local tax. The Department also says vendors located in Allegheny County or Philadelphia must collect the local tax, while vendors located elsewhere may collect it voluntarily to relieve purchasers of reporting use tax. Because the rules turn on where a sale originates and where property is used, check the Department's guidance before applying local tax to a shipment. Our Pennsylvania sales tax calculator shows current rates by location.

Due dates and the weekend rule

Monthly and quarterly returns are due on the 20th day of the month after the period ends. Semiannual returns are due August 20 for January through June and February 20 for July through December. If the 20th falls on a weekend or holiday, the report and payment are due the next business day. Our Pennsylvania sales tax due dates page also lists upcoming dates.

The Department's 2026 schedule (REV-819) lists the adjusted dates. Upcoming due dates for returns include:

ReturnPeriodDue date
Monthly and quarterlySeptember 2026 and Q3 2026October 20, 2026
MonthlyOctober 2026November 20, 2026
MonthlyNovember 2026December 21, 2026
Monthly and quarterlyDecember 2026 and Q4 2026January 20, 2027
SemiannualJuly to December 2026February 22, 2027

For monthly filers with prepayments, the same schedule shows the prepayment for the month ending September 30 due September 21, 2026, and for the month ending October 31 due October 20, 2026.

Filing a zero return

The Department says all registered businesses must file a sales tax return each reporting period, even if they owe no tax for the period, and that returns are to be filed whether or not taxable transactions occur. A missed return can lead to a Notice of Delinquency, which must be paid in full within 15 days or discussed with the Department's Delinquent Call Center. The Department's pages we reviewed do not describe the myPATH screens for a period with no activity, so follow the prompts in your account or ask the Department.

Amending a return

The Department's pages we reviewed do not publish step-by-step instructions for amending a sales tax return in myPATH, so confirm the process with the Department before you change a filed return. Some timing rules are published in the Retailer's Information guide (REV-717):

  • Refunds: A taxpayer generally has three years from the date of payment to petition for a refund of tax overpaid.
  • Assessments: Once a return is filed, the Department generally has three years to issue an assessment for additional tax owed, and longer in certain cases, such as fraud or failure to file a return. After an assessment, you have 60 days from its mailing date to petition for reassessment.
  • Amended returns are not appeals: The Department says it will not accept or process an original or amended return filed to challenge an assessment.

Payment methods and EFT rules

Pennsylvania requires payments of $1,000 or more to be made through electronic funds transfer. The electronic options are ACH debit, ACH credit, and credit card. The card processor charges a convenience fee based on the tax due. Failing to pay electronically when required can result in an assessment of a penalty equal to 3% of the total tax due, up to $500. Businesses below the $1,000 threshold can choose to pay electronically. Tax documents must still be filed even when payment is made by EFT.

The Department's TeleFile page also says payments of $1,000 or more may be made by certified or cashier's check delivered in person or by express mail, with the tax documents, by 4 p.m. Eastern time on the due date. Confirm which method applies to your account before relying on it.

TeleFile (1-800-748-8299) lets you file and pay by phone. The Retailer's Information guide describes it as a system for taxpayers who do not have computer access, who must submit a TeleFile Request Form with the reason (such as no internet access or a religious exemption) about 30 days before the due date. Call 717-787-1064 to request the form.

The vendor discount

For timely filed returns and payments, the vendor discount is the lesser of 1% of tax collected or $25 for a monthly filer, $75 for a quarterly filer, or $150 for a semiannual filer. The Department's discount Q&A explains that these limits add up to a $300 annual cap on the discount however often you file, and that the cap applies to sales, use, and hotel occupancy returns. The discount is apportioned between the state and local jurisdictions on the return. No discount is granted on a late return, and none is allowed on use tax reported.

Illustration only, not a Department example. A monthly filer that collects $1,800 in tax and files and pays on time calculates 1% of $1,800, which is $18. That is below the $25 monthly limit, so the discount is $18. If the same filer collects $4,000, 1% is $40, which exceeds the limit, so the discount is capped at $25.

Penalties and interest for late filing

  • Late return: An addition of 5% of the tax due for each month or fraction of a month a proper return remains unfiled, up to 25% of the tax for the period, and never less than $2.
  • Lost discount: No vendor discount is granted on a late return.
  • Interest: Calculated daily as tax times days late times the daily interest rate. The rate is set each January 1 based on the rate established by the U.S. Secretary of the Treasury, and published on form REV-1611.
  • EFT noncompliance: A penalty of 3% of the total tax due, up to $500.

If proper tax, interest, and additions are not paid, the Department makes an assessment. For a state-by-state comparison, see our guide to sales tax filing penalties and discounts by state.

Common Pennsylvania sales tax filing mistakes

  • Skipping zero returns. Every period needs a return, even with no taxable transactions.
  • Leaving out use tax. Licensees report use tax on the sales tax return, not separately, and no discount applies to it.
  • Missing local tax. Philadelphia and Allegheny County sales carry a local tax that is reported on the same return.
  • Ignoring AST prepayments. Once your third-quarter liability reaches $25,000, prepayments are due each month on top of the return, as separate payments.
  • Paying $1,000 or more by an unapproved method. That can trigger the EFT penalty.
  • Assuming the due date is always the 20th. Check REV-819 for dates that move because of weekends and holidays.
  • Filing late and losing the discount. The discount requires timely filing and payment.
  • Measuring nexus by the wrong period. The $100,000 threshold is measured by calendar year and includes nontaxable sales.

If you receive a sales tax notice

A missed or late return often leads to a letter. Our Pennsylvania sales tax notices guide explains the notices the Pennsylvania Department of Revenue sends, including Notice of Delinquency, Billing Notice, and Notice of Assessment. It also covers how to ask for penalty relief: Request for Compromise with a Board of Appeals petition (DBA-10, Request for Compromise). Check the date on the notice, match it to your filing period, and follow the instructions on the notice itself.
