How much can I claim?
You may claim the total of any amounts paid to the union for the previous financial year from 1 July - 30 June. For example, in this year's tax return, you will claim all amounts paid to the union between 1 July 2022 and 30 June 2023.
As the CPSU/CSA does not accept donations or levies to a strike fund, all amounts paid to the union are covered under ‘union fees’, so the total of any amounts paid may be claimed without exception. If you are a member of another union you should check with that union as to their fee structure before making your claim, or see the ATO guidance on claiming union fees.
