Yes, you can buy duty-free in France, but it is mostly beneficial for those living outside the European Union (including UK residents post-Brexit). When shopping in French cities, you can benefit from a VAT refund (Détaxe) of up to 12% if you spend more than €100.01 in a single store on the same day. You must present your original passport at the time of purchase and get a "PABLO" tax-free form. When leaving the EU, you must scan this form at a digital kiosk at the airport or train station before you check your bags to validate the export. For traditional duty-free shopping (liquor, perfume, tobacco), you can buy at the airport after passing through passport control. Be aware that since 2026, customs limits are strictly enforced: for example, bringing more than 1 liter of spirits or 200 cigarettes back to the US or UK may result in you paying the duty you "saved" in France. Always keep your receipts handy, as French customs (Douane) are quite diligent about checking the items you are claiming a refund for.
