Q2022 unit supportThis page supports the AAT Level 4 Diploma in Professional Accounting (Q2022). Check that this is the qualification route shown in your MyAAT account or by your training provider.

BNTA develops a structured approach to adjusted profits, capital allowances, losses and corporation-tax computations. Learners also consider how business decisions affect tax and how advice should be communicated professionally.

How to revise this unit

Common pitfalls
