Per-state pillar

Sales tax in Pennsylvania

Pennsylvania runs a single 6% statewide base administered by the Pennsylvania Department of Revenue (PA DOR), layered with a 1% Allegheny County Sales & Use Tax (SUT) add-on and a 2% Philadelphia SUT add-on — so most of the state runs 6% combined, Allegheny County (Pittsburgh) shipments run 7% combined, and Philadelphia shipments run 8% combined, with no other county-by-county overlay to track. This pillar walks through the PA DOR's default monthly-on-the-20th remittance cadence with semi-annual / quarterly carve-outs for low-liability accounts, the Wayfair-era single-prong $100K economic-nexus threshold (no transaction-count prong, no multi-year look-back), the marketplace-facilitator carve-out framing for direct-channel sales, the REV-1220 / REV-413 exemption-certificate series on manufacturing machinery and intermittent-isolated-sale exempt sales, and the operator-persona exemptions — restaurants (PA-prepared food + most beverages taxable on the full sales line), agencies (production-of-TPP work taxed at the production step), and service shops (installation labor separately stated from parts).

Pegged to the PA DOR's monthly-on-the-20th remittance calendar

Stillpost estimates your Pennsylvania sales-and-use-tax liability off your daily sales and lines it up with the PA DOR's monthly-on-the-20th remittance calendar via the myPATH portal — so the estimate lands on the day the PA DOR expects the return, not 10 days late on the last-day-of-the-month mental model California uses or 5 days late on the quarterly ST-100 mental model New York uses. Below the PA DOR low-liability threshold the PA DOR may move your account down to semi-annual or quarterly — the monthly-vs-quarterly reclassification trigger the PA DOR administers based on prior-12-month liability rather than auto-promoting on a single low-liability month; Stillpost keeps the same per-period view either way. The always-file-a-no-activity-month rule once the PA DOR Certificate of Registration has been issued is reflected in the same per-period view, so a zero-liability month still files the standard PA DOR return on the 20th.

On top of the cadence-pegged estimate, you also get the PA DOR's single-prong $100,000 Wayfair-aligned economic-nexus tracker (gross-receipts-only, no transaction-count prong, no multi-year look-back — PA-100 registration through myPATH starting on the next calendar month after crossing nexus), the marketplace-facilitator carve-out on the direct-channel side (a remote seller whose entire Pennsylvania business runs through an in-state marketplace facilitator is generally NOT required to register a PA-100 for those marketplace-channel transactions, but the direct-channel owner who runs an own-site or direct invoicing channel alongside the marketplace channel must always register a PA-100 and apply the rate at the ship-to address on every direct sale), the REV-1220 / REV-413 exemption-certificate series the PA DOR requires on file at the point of sale for manufacturing-machinery and intermittent-isolated-sale exempt sales, the operator-persona exemption treatment (restaurants: PA-prepared food + most beverages on the full sales line; agencies: production-of-TPP work taxed at the production step; service shops: installation labor separately stated from parts), and the tangible-personal-property vs. real-property line that drives construction / software / restaurant audit exposure under the PA DOR's enumerated-list posture.
