A Stockholm chauffeur service is a private car and driver booked ahead at a fixed price, run by an operator holding a taxi traffic licence (taxitrafiktillstånd) from Transportstyrelsen, the Swedish Transport Agency, under the Taxitrafiklagen (2012:211). Sweden has no separate limousine licence, so every chauffeur car carrying paying passengers is a licensed taxi in law, driven by someone holding a taxiförarlegitimation. The difference lies in how the trip is sold: a Arlanda airport transfer, an hourly car service or a black car to a meeting is agreed in advance, with the car class and the total settled before the day.
Swedish law makes that model explicit. A licensed car either runs an approved taximeter reporting to a certified redovisningscentral, or, since 2021, is connected to a licensed booking centre (beställningscentral) and carries only pre-booked trips at a fixed price, with proof of the price before departure and payment through the booking centre. A fixed fare agreed in advance is therefore lawful and normal here. A Stockholm car service booked through RYDES works that way, and the total already contains the 6 percent moms on passenger transport, the congestion tax, which taxis pay like everyone else, and the terminal fee at Arlanda. That is the honest case for a taxi alternative: the number cannot move on the day.
The same booking reaches beyond the inner city. Arlanda to Stockholmsmässan for the February fairs, Arlanda to Nynäshamn for a cruise embarkation, Stockholm to Uppsala and Sigtuna on the airport side of the county, and long fixed-fare runs such as Stockholm to Gothenburg and Stockholm to Oslo. Companies with people landing every week can move that onto a corporate travel account in Stockholm with central invoicing. RYDES quotes in euros; your card is charged in euros.
