Sales tax in Pennsylvania

Question 1

What is Pennsylvania's combined sales tax rate?

Accepted Answer

Pennsylvania runs a 6% statewide base rate administered by the Pennsylvania Department of Revenue (PA DOR). On top of that base, the PA DOR layers a flat 2% local add-on in Philadelphia and a 0.5% local add-on in Allegheny County — so most Pennsylvania ships-to run 6% combined, Allegheny County ships-to run 6.5% combined, and Philadelphia ships-to run 8% combined. There is no county-by-county discretionary surtax to track: the only overlay the PA DOR stacks is the Allegheny 0.5% and the Philadelphia 2%, both collected and remitted on the same PA DOR return rather than as separate filings.

Question 2

How often does Pennsylvania require sales tax filings with the PA DOR?

Accepted Answer

Most Pennsylvania sellers file monthly through the PA DOR on the 20th of the month following the reporting period — for example, the September return is due October 20. The PA DOR reclassifies a low-liability account to semi-annual (and, below the next PA DOR threshold, quarterly) once the prior-12-month liability drops below the PA DOR carve-out points; accounts that cross back up are re-promoted to monthly on the next reassignment. Registered sellers must file the PA sales-tax return even on no-activity months — a zero-liability return is still required once the PA DOR Certificate of Registration has been issued.

Question 3

When does a business need to register for Pennsylvania sales tax with the PA DOR, and how do marketplace facilitators interact with it?

Accepted Answer

Pennsylvania's economic-nexus threshold is $100,000 in gross receipts from Pennsylvania-bound sales in the prior twelve-month period — a single dollar-only prong with no transaction-count alternative (Pennsylvania-set under the Wayfair v. South Dakota decision rather than adopting the federal floor). Once crossed, the seller registers with the PA DOR via form PA-100 through the myPATH portal and receives a Certificate of Registration before the close of the month after crossing nexus. Marketplace-facilitator collection in Pennsylvania is narrower than in some sibling states; remote sellers who run both a marketplace channel and a direct own-channel must still register a PA-100 and apply the PA DOR-published rate at the ship-to address on every direct sale — facilitator collection does not relieve them of registration or of the direct-channel filing obligation.

Question 4

What are the common operator pitfalls with Pennsylvania sales tax, and how does the REV-1220 exemption-certificate series work?

Accepted Answer

Late filings under the PA DOR carry a penalty plus interest, both compounding against the unpaid balance; a single missed monthly return can quickly double the original liability when the late-filing penalty stacks on top of the interest, and skipped no-activity returns can move an account up the PA DOR audit-review list. The four most common operator pitfalls: confusing the sales-tax return (collected at the point of sale) with the use-tax return (self-assessed on stored or consumed items); missing the Allegheny/Philadelphia overlay rotation when the ship-to changes mid-order; forgetting to file a no-activity return once registered (the PA DOR still expects one); and skipping the REV-1220 exemption certificate on qualifying manufacturing-machinery and intermittent-isolated-sale exempt sales. Exempt categories include most unprepared groceries, prescription drugs, most medical equipment and prosthetics, manufacturing machinery and qualifying production-related tangible personal property, and occasional isolated sales not in the regular course of business.
