What a chartered accountant really does
Updated March 2026 - The work of a chartered accountant goes well beyond "doing the books". Depending on the engagement letter and the company's needs, the scope may include bookkeeping, review work, tax, payroll, reporting, management support and sometimes broader finance-organisation assignments.
The core classic missions
The traditional mission base usually includes:
- ▸bookkeeping and accounting supervision;
- ▸VAT and tax filings;
- ▸annual accounts and tax package preparation;
- ▸payroll and social obligations, depending on the retained scope;
- ▸support on selected management issues.

What depends on the engagement letter
A chartered accountant is not automatically responsible for "everything" around the business. The exact framework depends on the engagement entrusted, its scope and the professional standards that apply.
That is why the engagement letter matters so much. It tells the company what is included, what is not, which deliverables should be expected and what level of advisory input is really covered.
Why is this clarification so important for the business?
Because it helps management understand:
- ▸what is included;
- ▸what remains the responsibility of the business owner or the finance team;
- ▸which outputs can realistically be expected;
- ▸how much advisory support is actually part of the mission.
