Philadelphia changed who has to collect its sales tax this year. The city says its 2 percent local tax now follows where a taxable purchase is delivered, not where the seller is, that the state law took effect July 12, 2026 and applies to tax years after Dec. 31, 2025, and that enforcement would not start until Oct. 1, 2026, a date that has now passed. For a store outside the city that already collects Pennsylvania's 6 percent tax, that means a Philadelphia address can carry a local portion it did not carry before. The city is also a stage for dated events: the Philadelphia Flower Show lists March 12 to 21, 2027 at the Pennsylvania Convention Center, and the Marathon, the Penn Relays and Wawa Welcome America each post only their 2026 dates. This page puts both on one calendar.
Check how your store handles the local portion for Philadelphia deliveries. The city says enforcement was set to start Oct. 1, 2026, that businesses outside the city that already collect Pennsylvania tax must collect the 2 percent local tax on deliveries to Philadelphia customers, and that questions go to the Pennsylvania Department of Revenue. This is not tax advice.
The Marathon's site lists Nov. 20 to 22 for its 2026 weekend and no 2027 date. A weekend offer shown in the live offers widget gives that date a reason to be on the storefront, and it should end on the last day of the event.

Publish one offer for the length of the Flower Show and show it in the widget for those ten days. Because the show posts both its dates and a preview day on March 12, you can end the offer on March 21 and say so in the offer line.
Leave these two as month-level windows until the organizers post 2027 dates. The Penn Relays site lists April 23 to 25 for 2026 and Wawa Welcome America lists 2026 events from June 19 to July 4, so plan the offer shape now and set exact dates the day each site updates.

Run one offer at a time in the widget. Several live offers at once make it hard to tell which one moved orders, and a single offer per event lets you compare one event to the next.
Build it with the Today's offers widget template.
Requires: Growth plan or higher.
Schedule an offer for March 12 to 21, 2027 and let the storefront widget list it while it is live, so a visitor sees the offer and its end date without a banner redesign. Ten days is long enough to measure and short enough to cap.
A 50 dollar taxable product delivered to a Philadelphia address now carries a 2 percent local portion, which is 1 dollar, collected at purchase and paid to the Commonwealth, according to the city. If your offer compares totals, compare them before tax.
The city's beverage tax is a per ounce tax on distributors of sweetened beverages, and its page does not address shipments to consumers. A store that does not sell sweetened beverages can skip it, and one that does should ask the Department of Revenue.

Philadelphia runs a spring to fall run of citywide events, from a flower show in March to a marathon weekend in November, and a store that sells to Philadelphia addresses now has a local tax rule that follows the delivery address.
The City of Philadelphia says its 2 percent local sales tax now follows where a taxable purchase is delivered rather than the seller's location, that the new state law took effect on July 12, 2026 and applies retroactively to tax years after Dec. 31, 2025, and that enforcement would not start until Oct. 1, 2026.

The city's explainer says the new law requires businesses outside Philadelphia that already collect Pennsylvania's 6 percent sales tax to also collect Philadelphia's tax on taxable products delivered to Philadelphia customers, and that vendors collect it at the time of purchase and pay it to the Commonwealth of Pennsylvania.
