Yes. Pennsylvania’s destination-sourcing change applies to taxable sales delivered to customers in Philadelphia and Allegheny County, with a retroactive effective date covering tax years after December 31, 2025. The Pennsylvania Department of Revenue says it will not begin enforcing the new rules until October 1, 2026. That enforcement delay is not the same as a later effective date: sellers should review sales from January 1 through September 30, 2026, rather than assume those transactions are outside the rule.
For taxable deliveries to Philadelphia, the local rate is 2%; for taxable deliveries to Allegheny County, it is 1%, in addition to Pennsylvania’s 6% state sales tax. The change concerns local tax sourcing, not the state rate. Whether a particular seller must collect and remit depends on its Pennsylvania sales-tax obligations and the transaction. Check the Department of Revenue’s current instructions and your account and filing circumstances; the exact position depends on your circumstances — confirm with the state, or talk to us and we will check it for you.

What Pennsylvania’s destination-sourcing change means
Destination-based sourcing means the local sales-tax treatment is determined by where a taxable product or service is delivered, rather than simply where the seller’s business or point of sale is located. Under Pennsylvania’s current rule, the relevant destinations are Philadelphia and Allegheny County. The Department of Revenue describes the change as moving local tax from point-of-sale sourcing to point-of-destination sourcing.
For an online seller, that makes the customer’s delivery address important. A seller located outside either jurisdiction may still need to account for local tax on a taxable order delivered into one of them if the seller is required to collect Pennsylvania sales tax. Conversely, a seller’s location alone does not determine whether the Philadelphia or Allegheny local rate applies to a delivery elsewhere.
This is a local-tax sourcing change. Pennsylvania’s state sales-tax rate remains 6%, and the Department says state sales-tax and state and local use-tax rules have not changed. For more background, see Did Pennsylvania change local sales tax sourcing on October 1 and Must Pennsylvania orders use destination local-tax sourcing.
When the rule took effect—and when enforcement begins
The Department of Revenue states that the change has a retroactive effective date for tax years after December 31, 2025. In practical terms, the covered period begins January 1, 2026. The Department also says it will not begin enforcing the new rules until October 1, 2026, to give vendors time to adjust.
Those dates answer different questions. January 1, 2026 is the stated effective date for the covered tax years; October 1, 2026 is the date the Department says enforcement begins. The enforcement grace period does not, by itself, erase the retroactive effective date or establish that pre-October sales are exempt from local tax.
Accordingly, sellers should not treat October 1 as the first date on which the rule can matter. Review taxable sales delivered to the two jurisdictions from January 1 onward, including transactions before October 1, and follow the Department’s current instructions for reporting and any adjustments. If the treatment of earlier transactions is unclear, confirm it with the Department or have a Pennsylvania compliance professional review the facts.
Which counties and deliveries are affected?
The Department identifies Philadelphia and Allegheny County as the jurisdictions affected by this destination-sourcing change. The local rates are 2% for Philadelphia and 1% for Allegheny County. These are local additions to the 6% Pennsylvania state sales-tax rate, so the combined rates for taxable sales are 8% and 7%, respectively.
Use the actual delivery destination to determine whether an order is going to Philadelphia or Allegheny County; do not rely only on a city name, seller location, or a broad regional label. The Department points vendors to address and ZIP-code resources for identifying whether a customer’s address falls within either jurisdiction. ZIP codes can cross boundaries, so verify the address when the jurisdiction is uncertain.
The change does not introduce local sales-tax rates for every Pennsylvania county. The Department’s published local-tax guidance identifies Philadelphia and Allegheny County for this rule. For a delivery elsewhere in Pennsylvania, do not add either of these local rates merely because the seller is based in one of those places; apply the state’s current rules to the transaction.
Who must register, collect, and remit local tax?
The Department says vendors already required to collect and remit Pennsylvania’s 6% sales tax must collect and remit the applicable local tax on taxable sales to customers in Philadelphia or Allegheny County. The local amount depends on the delivery destination: 2% for Philadelphia or 1% for Allegheny County. The change does not mean every marketplace or online seller automatically has the same registration or collection obligation.
First determine whether your business is required to collect Pennsylvania sales tax, including whether your activities or sales create an obligation to register. Marketplace sales, direct website orders, and inventory stored in Pennsylvania can raise different compliance questions. A marketplace’s collection on some transactions does not necessarily resolve every obligation for your own direct sales or other Pennsylvania activity.
For context, review Economic nexus in Pennsylvania and, if you use marketplace-fulfilled inventory, Amazon FBA sales tax in Pennsylvania. These topics can affect whether you need to register and collect, but the answer depends on your business’s facts and the current state rules. Confirm your registration status and filing responsibilities with the Department or a qualified adviser.
How to handle sales made before October 1, 2026
Do not assume that sales made before October 1 are outside the change. Pennsylvania’s Department of Revenue states both that the rule applies retroactively to tax years after December 31, 2025 and that enforcement begins October 1, 2026. The Department’s published explanation therefore calls for reviewing covered taxable sales from January 1 through September 30, not simply ignoring them because they occurred during the enforcement grace period.
Start by identifying taxable transactions delivered to Philadelphia or Allegheny County during that period. Separate them by destination, transaction date, taxability, sales channel, and whether tax was collected by you or a marketplace. Compare the local tax treatment used at the time with the destination rate that applies, and retain records showing how you reached your conclusion.
The Department’s public summary establishes the retroactive date and delayed enforcement, but it does not, in the material cited here, spell out every seller’s correction method or the treatment of every filing already submitted. Do not guess whether to amend a return, make an adjustment, or take another step. Check current Department instructions for your account and filing period; if the answer is not clear, ask the Department or have a service provider review the transactions.

What to update before filing
Before preparing a Pennsylvania return, review the address and tax settings used for taxable orders. Make sure your records distinguish Philadelphia deliveries from Allegheny County deliveries and from other Pennsylvania destinations. Check that the correct local rate is associated with each covered destination and that the state tax is accounted for separately.
Reconcile orders across your own store and each marketplace channel. Compare order-level destination data, tax collected, refunds or cancellations, and the amounts included in your sales-tax records. Pay particular attention to transactions from January 1 through September 30, 2026, because the retroactive effective date and delayed enforcement date do not match.
Also confirm that your Pennsylvania registration, filing frequency, return periods, and reporting process are current. The Department says local taxes are reported through the local tax columns of the Pennsylvania sales and use tax return, but follow the current return instructions for your account and period.

When to get help with Pennsylvania compliance
Get help if you are unsure whether you must register, whether a marketplace collected the right tax, how to classify a delivery address, or how to treat pre-October 2026 transactions. A review is especially useful if you have already filed returns for periods beginning January 1, 2026, collected tax using the seller’s location, or have sales through several channels that do not reconcile cleanly.
