Pennsylvania sales tax for out-of-state customers generally does not apply when you ship or deliver the product to an address outside Pennsylvania. The exemption turns on where the customer physically takes possession of the goods, not on where the customer lives. Ship it to Ohio by UPS and you charge no PA tax. Hand it to that same Ohio customer at your counter in Erie and you owe the full state (and any local) rate. Getting this distinction wrong is one of the most common ways sellers end up with an audit assessment.
The Rule That Decides the Sale
Pennsylvania’s multi-state sales regulation, 61 Pa. Code § 32.5, sets the standard. When you sell tangible personal property and you are obligated to deliver it to a point outside Pennsylvania, or to hand it off to a common carrier for shipment to a point outside the state, the sale is not subject to Pennsylvania sales tax.1Pennsylvania Code Website. Pennsylvania Code 61 Pa. Code 32.5 – Multi-State Sales The delivery obligation should be visible on the face of the transaction: the order, the invoice, or the shipping contract shows you are responsible for getting the goods out of state.
The flip side is written into the same regulation. “Delivery in this Commonwealth to a nonresident purchaser does not make the transaction exempt.”1Pennsylvania Code Website. Pennsylvania Code 61 Pa. Code 32.5 – Multi-State Sales A New Jersey buyer who drives to your Philadelphia showroom and walks out with the product owes PA tax on that sale. A Maryland contractor who picks up materials at your Lancaster warehouse owes PA tax. Their home address does not save the sale. The point of possession does.
Delivery Methods That Preserve the Exemption
To keep an interstate sale exempt, you need a verifiable record showing the product left Pennsylvania before the buyer took control of it. Two methods work: shipment through a common carrier such as FedEx, UPS, or the U.S. Postal Service, or delivery in your own company vehicles to the out-of-state address.
A carrier is the cleaner option for most businesses because tracking numbers and delivery confirmations automatically document the destination. If you deliver with your own fleet, build a habit of collecting trip logs, fuel receipts, and signed delivery confirmations that name the drop-off address. The Department of Revenue can ask for this material years after the sale, so treat it as core business documentation rather than paperwork you toss once the invoice clears.
Documentation to Keep
Claiming interstate exemptions without proof is how sellers lose them in audits. For every out-of-state shipment, keep the bill of lading, freight receipt, tracking confirmation, or shipping manifest. Each record should show the customer’s name, the shipment date, and a delivery address outside Pennsylvania. If an auditor cannot see the goods leaving the state, they can reclassify the sale as taxable and assess the tax, interest, and penalties against you.
A four-year retention period is the safe standard. Pennsylvania’s REV-1220 exemption certificate carries a four-year retention requirement, and applying the same window to your out-of-state shipping records keeps everything on one clock.2Pennsylvania Department of Revenue.

Digital Products Follow the Billing Address
Physical goods are sourced by delivery destination. Digital products are not. Under Act 84 of 2016, Pennsylvania imposes its six percent sales tax on digital products transferred electronically, including video, music, e-books, apps, games, and prewritten software.3Commonwealth of Pennsylvania. Digital Products | Department of Revenue For these sales, the taxable location is the customer’s billing address on file with you, not any shipping address.
The outcome for true out-of-state customers is the same: Pennsylvania sales tax does not apply to items delivered to customers outside the state, whether transferred electronically or otherwise.3Commonwealth of Pennsylvania. Digital Products | Department of Revenue The catch is that your billing-address data has to be right. If your records show a Pennsylvania billing address, you owe the tax even if the customer happens to be sitting in another state when they download the file.
Philadelphia and Allegheny County Add-Ons
Pennsylvania’s base rate is six percent statewide. Philadelphia adds two percent for an eight percent total, and Allegheny County adds one percent for a seven percent total.4Commonwealth of Pennsylvania. Tax Rates | Department of Revenue Both local taxes follow the same destination-based sourcing as the state tax. Ship from a Philadelphia warehouse to a customer in Virginia and neither the six percent state tax nor the two percent Philadelphia add-on applies. Let that same Virginia customer walk out of the Philadelphia location with the item in hand and you collect the full eight percent.
The local rate is the rate at the destination, not the rate where your business sits. A shipment from Pittsburgh to Centre County carries only the six percent base rate. A shipment from anywhere in the state to a Philadelphia address carries eight percent.
You May Still Owe Tax in the Customer’s State
This is the part sellers most often miss. Skipping PA tax on an out-of-state shipment does not mean the sale is tax-free. Since the U.S. Supreme Court’s 2018 decision in South Dakota v. Wayfair, states with a sales tax can require out-of-state sellers to collect and remit tax once the seller crosses certain sales thresholds in that state, without needing any physical presence there.
Pennsylvania applies this same rule to sellers based elsewhere: any business making more than $100,000 in annual gross sales into Pennsylvania must register, collect, and remit PA sales tax, with no separate transaction-count trigger.5Commonwealth of Pennsylvania. Online Retailers | Department of Revenue Other states apply the mirror image of that rule to you when you ship into their borders.
Most states set the threshold at $100,000 in annual sales, though several are higher. California uses $500,000. Alabama and Mississippi use $250,000. Some states also add a 200-transaction trigger that applies regardless of dollar volume, and the measurement periods vary. If you sell meaningful volume into a particular state, look up that state’s specific threshold before assuming you have no obligation there. A destination state that discovers uncollected tax typically assesses it against the seller, with penalties and interest layered on top.
Quick Reference by Scenario
- You ship from PA to an out-of-state address by UPS, FedEx, USPS, or your own truck: no PA sales tax, keep the shipping documentation.
- A customer from another state picks up the item at your PA location: charge PA sales tax at the location’s rate, including any local add-on.
- You sell a digital product to a customer whose billing address is outside PA: no PA sales tax.
- You sell a digital product to a customer whose billing address is inside PA, wherever they physically are: PA sales tax applies.
- Your out-of-state sales into a particular state get large: check that state’s economic nexus threshold, because you may owe tax there.
The Pennsylvania answer is simple once the delivery point is fixed. The harder question is often the second one, in the buyer’s state, and it deserves its own look whenever your volume into that state starts to grow.
