Which state is easier for sellers?

For low-revenue sellers: nexus triggers first in Pennsylvania because of its $100,000 threshold. If you cross that first, you register there first.

On rate: Pennsylvania is friendlier for customers with a combined state + local rate of 6.34% vs 8.99%.

Neither state has a transaction-count trigger — only the dollar threshold matters.

California — nexus note

California sales tax nexus and economic nexus threshold: CDTFA guidance says remote retailers must register and collect California use tax when total combined sales of tangible personal property for delivery into California exceed $500,000 during the preceding or current calendar year. California uses a sales-only threshold — no transaction-count test. AB 147 replaced the earlier $100,000/200-transaction Wayfair threshold with the current $500,000 standard, and related-person sales count toward the threshold. CDTFA marketplace guidance says sellers include both direct California sales and marketplace-facilitated sales when testing the $500,000 threshold, but sellers whose California sales are entirely facilitated by registered marketplace facilitators may not need separate registration for those marketplace transactions. Direct-to-consumer sales outside a marketplace remain the seller's own collection responsibility once California nexus is met.

Pennsylvania — nexus note

Pennsylvania sales tax nexus and economic nexus threshold: more than $100,000 in annual Pennsylvania gross sales, measured by calendar year, creates economic presence for remote sellers and marketplace facilitators (eff. 2019-07-01 under Act 13 of 2019 and Sales and Use Tax Bulletin 2019-01). Pennsylvania uses a sales-only threshold -- no transaction-count test. Gross sales include taxable and nontaxable sales across channels. A marketplace facilitator with no Pennsylvania physical presence counts both facilitated and direct Pennsylvania sales; a marketplace seller counts direct sales plus marketplace sales only when the facilitator does not collect Pennsylvania sales tax on its behalf. After the first collection year, Pennsylvania measures prior calendar-year sales and starts the annual collection period in the second quarter. The state rate is 6%, with local add-ons in Allegheny County (+1%) and Philadelphia (+2%). Pennsylvania 2026 sales/use tax filing calendars list monthly, quarterly, semi-annual, and monthly-with-prepayment filer tracks; returns are due even when no taxable transactions occur in the period. Sellers without physical presence can use a Pennsylvania-certified service provider for registration, filing, collection, and remittance support.

Which has the lower sales tax rate, California or Pennsylvania?
Pennsylvania has the lower combined state and local sales tax rate at 6.34%, compared with 8.99% in California. These are the statewide base rate plus the average local rate; the exact rate depends on the customer's delivery address. As of 2026-05-30.
Do I need to register for sales tax in both California and Pennsylvania?
It depends on where you cross each state's economic nexus threshold (or have physical presence there). California's published threshold is $500,000, and Pennsylvania's is $100,000. You generally register in a state only once you cross its threshold, so you may have an obligation in one, both, or neither.

When did economic nexus take effect in California and Pennsylvania?
California's economic nexus rule took effect on 2019-04-01, and Pennsylvania's took effect on 2019-07-01. Both stem from the 2018 South Dakota v. Wayfair Supreme Court decision, which let states require remote sellers to collect once an economic threshold is met.
