All three CBEs must usually be passed (or exemptions applied for as appropriate) before you can enter for your final CTA tax exam (i.e. passed by the end of February for the May exams or the end of August for the November exams).

For May 2025 exams, there is a late entry period which will run from 1 March 2025 to 19 March 2025.
An additional late entry fee of £115 will apply in this period.
Please note that exam centre capacity is now very limited and we cannot guarantee you will be able to make an exam entry during the late entry period.
You are not permitted to complete your CBEs during the late exam entry period (and still enter for your last tax exam that session).
