The congestion tax area encompasses essentially the entire Gothenburg City Centre and the E6 main road passing the city. Curiously, cars passing the city are also taxed, providing no incentive to drive around the city rather than through the city, contrary to most other congestion charge schemes in the world. As an example in Stockholm, only vehicles entering and exiting the central city are taxed, not those passing by the city on the main highway. In Stockholm, there is no need to tax people driving creative detours.

There are unmanned electronic control points (in Swedish: betalstation, literally payment station) at all entrances to this area. The congestion tax is applied when passing stations in both directions. There is also a control point on the west of the city on Älvsborgsbron, far from the main congestion charge zone, which is perhaps odd since neither side of the bridge is within a charging zone. The effect of placing a control point here effectively means that any vehicle wishing to drive along the west coast of Sweden past Gothenburg must pay the congestion charge, with the shortest detour to avoid the charge adding 45 km to a journey, via Partille.

The amount of tax payable depends on what time of the day a motorist enters or exits the congestion tax area. There is no charge on Saturdays, Sundays, public holidays or the day before public holidays, nor during nights (18:30 – 05:59), nor during the month of July.

The maximum amount of tax per vehicle per day is 60 SEK (6.40 Euro, 7.70  USD). 22 SEK is around 2.35 Euro or 2.80 USD.^[1]

If a vehicle passes two stations within one hour, only the higher tax is paid.

Some vehicles are exempt from tax, although notably environmentally friendly vehicles (mainly electric or natural gas or ethanol fuelled) must still pay.

Foreign registered vehicles were exempt until 2014 mainly for practical reasons, hard to get access to foreign car registers, and to claim payment from foreigners. But they are included now because of objections from companies about unfair taxation, and because the "Eurovignette" EU directive (1999/62/EC article 7 and 2006/38/EC) requires that user charges may not discriminate on the grounds of the nationality of the haulier or the origin of the vehicle. The authority has contracted a collection agency, ParkTrade,^[2] which in turn has contracted collection agencies in the most common countries that charge the owners, using the brand name EPASS24.^[3]

Rental car customers will be billed afterwards, typically around two months after the rental period, because the authority takes its time to calculate, decide and bill the tax. For this reason it is not possible for the customer to quickly pay the tax. Administrative fee and VAT will be added even if the tax has no VAT, because the payment to the rental company is legally seen as rental fee. Some rental company adds a fixed fee in order to cover the tax cost if renting in Gothenburg.^[4]
