The Swedish Tax Agency is a government agency in Sweden responsible for national tax collection and administering the population registration. The agency was formed on 1 January 2004 through the merger of the Swedish National Tax Board (Riksskatteverket) and the then 10 existing regional tax authorities (skattemyndigheter). The Swedish Tax Agency (and prior to that, the Swedish National Tax Board) was also formerly the parent agency of the Swedish Enforcement Administration (Kronofogdemyndigheten). Since 1 July 2008, the Swedish Enforcement Administration is an independent agency but with close administrative ties to the Swedish Tax Agency. The agency has local offices in over a hundred cities across Sweden, with the headquarters located in Solna, Stockholm County.
