Learning Objectives
What you need to know and understand
- Understand the sources of information used when assessing risk, Understand the common areas of risk, and how to share information on risk
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for clearly identifying at least three internal and external sources of risk information, such as client records, third-party data feeds, and HMRC alerts.
- Demonstrate ability to categorise common risk areas (e.g., cash-based trades, property income, employment expenses) with specific examples of what constitutes a red flag in each.
- Provide a well-structured explanation of protocols for escalating risk findings, including internal reporting lines and when to make a disclosure to HMRC under the Code of Practice 9.
Assessment Guidance
Guidance for achieving higher grades
- 💡In scenario-based questions, always link the source of risk information to the specific risk area and the appropriate action—don't just list potential issues.
- 💡Use the 'Plan, Source, Assess, Share' framework to structure your answers on risk handling, showing a systematic approach to align with HMRC's risk-based compliance model.
- 💡Reference the AAT's Professional Standards and HMRC's Compliance Handbook when justifying your risk-sharing decisions to demonstrate ethical and regulatory awareness.
- 💡Always show your workings clearly, especially for calculations, as marks are awarded for method.
- 💡Use the correct tax year rates and allowances; exam questions will specify the year, so apply the relevant figures.
Common Mistakes
Common errors to avoid in your coursework
- Treating risk assessment as a one-off task rather than an ongoing, iterative process throughout the tax year and during return preparation.
- Overlooking indirect risk indicators such as lifestyle discrepancies or unexplained wealth, focusing only on numerical inconsistencies.
- Assuming all risk information must be shared with HMRC immediately without first evaluating the client's explanation or considering legal professional privilege.
- Misunderstanding that all income is taxed the same way; in fact, different types (employment, trading, savings) have specific rules.
- Believing that capital gains tax applies to all asset sales; only chargeable assets (e.g., shares, property not main residence) are taxable.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: Calculate the income tax liability for a taxpayer with employment income of £45,000 and savings income of £2,000 for 2023/24. Assume personal allowance of £12,570 and basic rate band of £37,700.
- 1.Step 1: Total income = £45,000 + £2,000 = £47,000.
- 2.Step 2: Deduct personal allowance: £47,000 - £12,570 = £34,370 taxable income.
- 3.Step 3: Apply basic rate (20%) to first £37,700 of taxable income: £34,370 × 20% = £6,874.
- 4.Step 4: No higher rate as taxable income is below £37,700. Total tax = £6,874.
Question: A sole trader has trading profits of £60,000 for 2023/24. Calculate Class 4 National Insurance contributions due. Rates: 9% on profits between £12,570 and £50,270, 2% on profits above £50,270.
- 1.Step 1: Lower limit £12,570, upper limit £50,270.
- 2.Step 2: Profits between limits: £50,270 - £12,570 = £37,700. NIC = £37,700 × 9% = £3,393.
- 3.Step 3: Profits above upper limit: £60,000 - £50,270 = £9,730. NIC = £9,730 × 2% = £194.60.
- 4.Step 4: Total Class 4 NIC = £3,393 + £194.60 = £3,587.60.
