UK Uncut was a network of United Kingdom-based protest groups established in October 2010 to protest against cuts to public services and tax avoidance in the UK. Various sources have described the group as left-wing in its political orientation.

Tax avoidance is the legal usage of the tax regime in a single territory to one's own advantage to reduce the amount of tax that is payable by means that are within the law. A tax shelter is one type of tax avoidance, and tax havens are jurisdictions that facilitate reduced taxes. Tax avoidance should not be confused with tax evasion, which is illegal. Both tax evasion and tax avoidance can be viewed as forms of tax noncompliance, as they describe a range of activities that intend to subvert a state's tax system.
