Topic Synopsis
This subtopic explores the statutory and case law definitions of 'plant and machinery' for capital allowances, which determine the deductible expenditure for tax purposes. Professionals must apply these principles to distinguish between qualifying and non-qualifying assets, and navigate complex rules for contributions, group sales, and transactions with connected persons to accurately compute allowances.
Key Concepts & Core Principles
- Income Tax: Understand the calculation of taxable income, including employment income, trading profits, property income, and savings/dividend income. Key elements include personal allowance, tax bands (basic, higher, additional), and reliefs such as the marriage allowance.
- National Insurance Contributions (NICs): Differentiate between Class 1 (employees), Class 2 (self-employed), Class 4 (self-employed profits), and Class 1A/1B (employer). Know thresholds and rates for each class.
- Capital Gains Tax (CGT): Compute gains on disposal of assets, apply annual exempt amount, and understand reliefs such as principal private residence relief, entrepreneurs' relief (now Business Asset Disposal Relief), and gift relief.
- Value Added Tax (VAT): Grasp the principles of output tax, input tax, VAT rates (standard, reduced, zero, exempt), and partial exemption. Understand VAT registration thresholds and schemes like the Flat Rate Scheme.
- Tax Administration: Know the self-assessment system, including filing deadlines (31 January and 31 October for paper), payment dates, penalties for late filing/payment, and HMRC enquiry powers.
Exam Tips & Revision Strategies
- Memorize key cases like Yarmouth v France and consistently apply its functional test to determine if an asset serves the business.
- For group sales, verify if both companies remain in the group post-sale to determine if the nil gain/nil loss rule applies.
- Always adjust the qualifying expenditure by any public or non-group contribution before calculating writing down allowances.
Common Misconceptions & Mistakes to Avoid
- Assuming that all fixtures are automatically plant without applying the functional test.
- Ignoring anti-avoidance provisions that substitute market value for sale proceeds between connected persons.
- Failing to restrict the cost of an asset by any contributions received from non-group entities.
Examiner Marking Points
- Award credit for correctly distinguishing between plant and building based on the functional test from case law.
- Expect accurate adjustment of asset costs for contributions received before computing allowances.
- Recognize correct treatment of group sales, including degrouping adjustments where applicable.
- Credit application of market value rules for connected person transactions to prevent tax avoidance.
