Level 3 — Business Taxation

Level 3 starts with the questions every business return answers — what entity is this, what method does it use, and how does income reach the owners — then works through each return type. Learners first build the books-to-return bridge from a trial balance, because most business returns start from the client's accounting, not from tax forms.
