The article discusses how the introduction of common European Union tax (VAT) regulations may affect the voluntary sector in Sweden. Historically nonprofit organizations in Sweden have enjoyed tax exemption given that their activities are considered to be of a common good purpose. The Commission of the European Union considers the tax exemption to be too generous in the case of Sweden and that it may distort competition in the free market.

The EU policy is interpreted by many nonprofit actors as threatening the existing institutional setting.
