Core concepts
Concept 1
Taxable business profit begins with the appropriate records and adjusts for the tax treatment of income, expenditure and capital items.
Exam cue: Confirm the assessment Finance Act, accounting period and elected basis before applying any rate or allowance.
Concept 2
Capital allowances replace accounting depreciation for qualifying expenditure and depend on asset, pool, period and private-use facts.
Exam cue: Separate accounting adjustment, capital-allowance computation, loss relief and partner allocation.
Concept 3
Partnership profit is computed for the business and then allocated between partners under the applicable profit-sharing arrangements.
Exam cue: Use the official assessment tax tables rather than memorised thresholds.
