Details

A Form AR21 is used by trade unions to make an annual return to the Certification Officer.

Additional reporting requirements resulting from the Trade Union Act 2016 which came into effect from 1 March 2017 (for reporting periods that begin on the day after 1 March 2017):

Unions whose reporting periods begin on the day after 1 March 2017 must now report on ballots held in respect of industrial action by the trade union during the reporting year and details of any industrial action taken during that period. For those unions with political funds there is a requirement for additional information for political fund expenditure.

All trade unions must complete the new pages 18-21 on ballots held and industrial action taken. Guidance on completing this section is at notes 74-80 of the guidance notes.

Those trade unions who hold Political Funds must complete pages 9 and 9i – 9vii. Guidance on how to complete this section is at notes 24-33 of the guidance notes.

AR21s not completed with this additional information will not comply with the duties on trade unions as provided in the Trade Union and Labour Relations (Consolidation) Act 1992 (as amended by the Trade Union Act 2016).
