Pennsylvania Marketplace Facilitator Law: eBay and Walmart Marketplace Sellers and the $100,000 Threshold

Pennsylvania's Marketplace Facilitator Law: Act 45 of 2016 and the 2019 Update

Pennsylvania was an early mover on marketplace facilitator legislation. Act 45 of 2016 initially established a notice-and-report regime requiring certain remote sellers and marketplace facilitators to either collect Pennsylvania sales tax or notify buyers of their use-tax obligations. The 2019 update — enacted in the wake of South Dakota v. Wayfair — converted this into a full collection mandate, requiring marketplace facilitators that exceed the $100,000 gross revenue threshold to collect and remit PA's 6% sales tax on all facilitated sales.

Under the statute, a marketplace facilitator is defined as a person who contracts with a marketplace seller to facilitate the sale of the seller's products through the facilitator's marketplace. The facilitator must list or advertise the products, collect payment from buyers, and transmit payment to sellers. eBay, Walmart Marketplace, Amazon, and Etsy all meet this definition and have been collecting Pennsylvania sales tax since July 1, 2019.

The critical structural difference between Pennsylvania and most other states is the absence of a transaction-count threshold. PA's economic nexus standard — for both remote sellers and marketplace facilitators — is $100,000 in gross revenue only. There is no 200-transaction alternative. This means:

• A seller doing 500 transactions totaling $80,000 into PA has no economic nexus based on those numbers alone
• The same seller in Georgia (which uses $100K or 200 transactions) would already have nexus on the transaction prong
• PA's threshold is purely dollar-based — high-volume, low-ticket sellers get more runway before triggering nexus

eBay's Facilitator Status in PA: What eBay Remits vs. What You Still Owe

eBay is a registered marketplace facilitator in Pennsylvania and collects the 6% PA sales tax on all orders facilitated through its platform. This covers fixed-price listings, auction sales, and Buy It Now transactions shipped to Pennsylvania addresses. eBay handles the full collection and remittance cycle — you do not need to separately collect or remit tax on eBay-facilitated PA sales.

However, eBay's facilitator coverage has clear boundaries:

Walmart Marketplace's Remittance Obligations and Independent Nexus Triggers

Walmart Marketplace is a registered marketplace facilitator in Pennsylvania and collects the 6% PA sales tax on all third-party seller orders placed through Walmart.com. This applies to both Walmart Fulfillment Services (WFS) orders and seller-fulfilled orders — as long as the sale is facilitated through Walmart's marketplace, Walmart handles collection and remittance.

But Walmart's facilitator status does not eliminate your independent nexus obligations in two important scenarios:

Scenario 1: Physical presence in Pennsylvania. If you store inventory in a Pennsylvania warehouse (including Walmart's own WFS fulfillment centers located in PA), maintain an office, or have employees in the state, you have physical nexus independent of any marketplace facilitator arrangement. Physical nexus requires you to register with the PA Department of Revenue and collect tax on all non-facilitated Pennsylvania sales — regardless of whether your revenue crosses the $100K economic nexus threshold.

Scenario 2: Multi-channel sales exceeding $100K. If your combined Pennsylvania sales across Walmart Marketplace, eBay, Amazon, your own website, and any other channels exceed $100,000, you have economic nexus. Walmart's collection on Walmart.com orders reduces your remittance — but you must still register and handle tax on all non-facilitated channels.

This is a common trap for Walmart Marketplace sellers who assume that because Walmart collects tax, they have no PA obligations. If you use WFS and Walmart routes your inventory to a Pennsylvania fulfillment center, you may have physical nexus in PA through your stored inventory — triggering an independent registration requirement that exists regardless of Walmart's facilitator remittance.

PA's “Already-Remitted” Deduction Rule: How to Avoid Double-Paying

Pennsylvania's “already-remitted” deduction is one of the most misunderstood — and most important — aspects of multi-channel selling in the state. Here is how it works:

When you file your PA-100 sales tax return, you report your total gross sales delivered into Pennsylvania across all channels. This includes eBay sales, Walmart Marketplace sales, Amazon sales, your own website sales, and any other channels. You then apply a deduction for tax already collected and remitted by marketplace facilitators. The net taxable amount is only the revenue on which you are responsible for collection.

Documentation is critical. The PA Department of Revenue may request verification that the deducted amounts were actually remitted by facilitators. Keep the following for each platform:

• Monthly or quarterly settlement reports showing PA-specific sales and tax collected
• Tax remittance confirmations from each platform's seller dashboard
• 1099-K forms for cross-referencing total gross sales against remittance records

Reconciling Multi-Platform 1099-K Income Against Facilitator Remittances

If you sell on eBay and Walmart Marketplace, you will receive a 1099-K from each platform reporting your gross payment volume. These 1099-K amounts will not match the sales tax that each facilitator remitted to Pennsylvania — and that discrepancy is expected. Here is why and how to reconcile.

Why the numbers differ: A 1099-K reports total gross payments received — the full sale price of every transaction, including shipping, handling, and sales in all states. The facilitator's PA tax remittance is only 6% of the taxable portion of PA-destined sales. These are fundamentally different numbers measuring different things.

Reconciliation process: For each platform, download the state-level sales report and the tax remittance report from your seller dashboard. Filter to Pennsylvania. Compare:

• Gross PA sales (from settlement report) — this feeds your “total gross sales” line on the PA-100
• PA tax collected by facilitator (from tax report) — this feeds your “already-remitted” deduction
• Difference — should be explainable by exempt sales, non-taxable items, or resale certificate transactions

If you find unexplained gaps — taxable sales where the facilitator did not collect — investigate before filing. Common causes include product category misclassification (the platform incorrectly marked an item as exempt) or address errors (the platform routed the order to the wrong state). Resolve these with the platform's seller support before your filing deadline. For PA filing deadlines and schedules, see the Pennsylvania sales tax filing deadlines guide.

Worked Example: $60K on eBay + $50K on Walmart + $30K Direct

Let's walk through a concrete scenario. You sell refurbished electronics across multiple channels and have the following Pennsylvania sales profile over the past 12 months:

Threshold analysis: Your combined Pennsylvania revenue is $140,000 — above the $100,000 threshold. You have economic nexus. (Note: even if your direct website sales were only $5,000, your combined total of $115,000 would still exceed the threshold.)

What you owe: On your PA-100 return, report $140,000 in total gross sales. Deduct $110,000 in facilitator-remitted sales (eBay $60K + Walmart $50K). Net taxable: $30,000. Tax due: $30,000 × 6% = $1,800.

What happens if you skip registration: The $30,000 in direct website sales goes untaxed. After two years of non-compliance:

The uncollected tax comes out of your pocket — you cannot retroactively charge buyers. For the full penalty and interest structure, see the Pennsylvania sales tax penalties guide. For step-by-step registration instructions, see how to register for Pennsylvania sales tax.
