When to choose Pennsylvania vs Washington
Pennsylvania charges 6% vs 6.5% in Washington, a 0.50-point spread the buyer pays at title transfer. Pennsylvania requires title transfer within 20 days; Washington allows 15. Tight 15-day deadlines push back-dated late fees onto buyers who delay. Pennsylvania publishes MV-4ST as the official bill of sale form; Washington accepts a generic bill of sale that includes the federally-required odometer disclosure. For a RV sale comparison, the buyer-side cost stack is dominated by sales/use tax, title fee, and any inspection or notary trip. Sellers should match the bill of sale format to the buyer's titling state because the buyer files the title transfer, not the seller.
Cross-state transfer: Pennsylvania to Washington
If the RV moves from Pennsylvania to Washington after the sale, the buyer registers and titles in Washington — not Pennsylvania. The seller's bill of sale should still match Pennsylvania sale-side conventions (because the sale happened there), but the buyer takes that bill of sale plus the endorsed Pennsylvania title to Washington DOL within 15 days of arrival. Washington will assess 6.5% sales or use tax on the purchase price when the new title is issued. Washington requires a VIN inspection for vehicles arriving from out of state — WA requires a VIN inspection by a DOL inspector, law enforcement, or licensed vehicle dealer for out-of-state titles with no VIN visible on the vehicle. The federal odometer disclosure rules apply regardless of which state owns the title at sale time; RVs newer than 2011 need a written odometer reading on the bill of sale or title. If a lien existed on the Pennsylvania title, the Pennsylvania lienholder must release it (MV-38L) before Washington DOL will issue a clean title to the buyer.
