What is the difference between income tax and national insurance?

Income tax is a tax on your total income (earned and unearned) calculated using progressive rates and personal allowances. National Insurance Contributions (NICs) are paid on earned income (employment or self-employment) and fund state benefits like the NHS and pensions. NICs have different classes and thresholds, and unlike income tax, they are not charged on investment income.

How do I calculate capital gains tax on shares?

To calculate CGT on shares, determine the gain by subtracting the cost of acquisition (including incidental costs) from the disposal proceeds. You can use the annual exempt amount (£3,000 for 2024/25) to reduce taxable gains. Shares are usually matched using the 'same day' rule and 'bed and breakfasting' rules. Gains are taxed at 10% for basic rate taxpayers and 20% for higher rate taxpayers.

What VAT schemes are available for small businesses?

Small businesses can use the Flat Rate Scheme, where you pay a fixed percentage of turnover (varies by trade) instead of calculating input tax. The Cash Accounting Scheme allows you to account for VAT when payment is received/paid, not when invoices are issued. The Annual Accounting Scheme lets you make advance payments and file one return per year. Each scheme has eligibility criteria and thresholds.

When is the deadline for filing a self-assessment tax return?

For the 2023/24 tax year, the paper return deadline is 31 October 2024, and the online return deadline is 31 January 2025. If you miss the deadline, you face an automatic £100 penalty, with further penalties for longer delays. Payment of tax owed is also due by 31 January 2025.

What is entrepreneurs' relief and how does it work?

Entrepreneurs' Relief (now called Business Asset Disposal Relief) reduces the CGT rate to 10% on qualifying gains up to a lifetime limit of £1 million. It applies to disposals of a business, shares in a trading company (with certain conditions), or assets used by the business. You must have owned the business for at least two years before disposal.

How do I treat dividends for income tax purposes?

Dividends are taxed at 8.75% for basic rate, 33.75% for higher rate, and 39.35% for additional rate taxpayers (2024/25). You have a dividend allowance of £500 (2024/25) which is tax-free. Dividends are treated as the top slice of income, so they are taxed after other income. No National Insurance is payable on dividends.

Assessment Guidance

Guidance for achieving higher grades

💡Use specific legislation references (e.g., Finance Act, VAT regulations) when discussing requirements and penalties to demonstrate depth of knowledge.
💡In case studies, always link the compliance checks to HMRC's stated compliance strategy (e.g., 'Promote, Prevent, Respond').
💡Practice applying penalty calculations to scenario-based questions, showing the escalation from failure to notify to daily penalties.
💡Always show your workings clearly, especially when calculating tax liabilities. Examiners award marks for method even if the final answer is wrong, so break down each step (e.g., separate income types, apply allowances in correct order).
💡Memorise key thresholds and rates (e.g., personal allowance £12,570, basic rate band £37,700 for 2024/25) but double-check the tax year in the exam. Use the provided tax tables accurately.
💡For VAT, practice completing a VAT return (Box 1-9) from given data. Common errors include misclassifying exempt vs zero-rated supplies or forgetting to adjust for partial exemption.

Common Mistakes

Common errors to avoid in your coursework

Assuming that HMRC only checks records during a formal investigation, rather than understanding the continuous compliance monitoring.
Misunderstanding the retention period for records (e.g., 5 years for income tax vs. 6 years for VAT) or failing to differentiate between digital and paper requirements.
Believing that penalties are only financial, whereas serious failures can lead to criminal prosecution.
Misconception: All income is taxed at the same rate. Correction: Income tax is progressive, with different rates for different types of income (e.g., savings income may have a 0% starting rate) and personal allowances that reduce taxable income.
Misconception: Capital gains tax is only payable on property sales. Correction: CGT applies to many assets, including shares, business assets, and personal possessions worth over £6,000, though main residences are usually exempt.
Misconception: VAT is always 20%. Correction: VAT rates include standard (20%), reduced (5%), and zero-rated (0%) supplies, and some items are exempt (e.g., insurance, education).
