1Which of the following best describes a direct tax?
A.A tax charged on spending, collected by the seller
B.A tax charged directly on the income, profits or gains of the person who bears it
C.A tax that always rises as a percentage of income
D.A tax collected only from companies
Explanation: A direct tax is levied directly on the income, profits or gains of the person who ultimately bears it, such as income tax or corporation tax. Indirect taxes, such as VAT, are charged on spending and collected by an intermediary.
2A tax takes a higher proportion of income from those on high incomes than from those on low incomes. This tax is best described as:
A.Regressive
B.Progressive
C.Proportional
D.Indirect
Explanation: A progressive tax takes a rising proportion of income as income increases. UK income tax, with its rising rate bands, is the classic example of a progressive tax.
3Which of the following is an objective of a good tax system as commonly described by the principle of 'economy'?
A.Tax should be as high as possible to maximise revenue
B.The cost of collecting the tax should be small relative to the revenue raised
C.Tax should always be a flat rate
D.Tax should only ever be charged on companies
Explanation: The principle of economy (one of Adam Smith's canons of taxation) states that the cost of collecting a tax should be small in relation to the amount raised. An efficient system does not waste a large share of revenue on administration.
4What is the key difference between tax avoidance and tax evasion?
A.Avoidance is illegal; evasion is legal
B.Avoidance uses the law to reduce tax; evasion involves illegally hiding income or facts
C.They are the same thing
D.Avoidance applies only to companies; evasion only to individuals
Explanation: Tax avoidance uses lawful arrangements to reduce a tax liability, whereas tax evasion is illegal and involves deliberately misrepresenting or concealing income, gains or facts from HMRC. Evasion is a criminal offence.
5Under the ICAEW Code of Ethics, which of the following is one of the five fundamental principles?
A.Profit maximisation
B.Confidentiality
C.Minimising the client's tax at all costs
D.Avoiding all contact with HMRC
Explanation: Confidentiality is one of the five fundamental principles, alongside integrity, objectivity, professional competence and due care, and professional behaviour. A member must not disclose client information without proper authority.
6A tax adviser acts for two companies that are bidding against each other for the same contract. This situation is an example of which ethical threat?
A.Self-interest threat
B.Self-review threat
C.Conflict of interest
D.Intimidation threat
Explanation: Acting for two clients whose interests directly oppose each other creates a conflict of interest. The adviser must consider safeguards such as disclosure and consent, or may have to decline to act for one party.
7If a tax adviser discovers during routine work that a client has been deliberately concealing income from HMRC and the client refuses to correct it, the adviser should normally:
A.Ignore it to protect client confidentiality
B.Cease to act for the client and consider their reporting obligations, including a money-laundering report
C.Correct the client's return without telling the client
D.Pay the tax on the client's behalf
Explanation: Where a client refuses to disclose deliberate concealment, the adviser should usually cease to act and consider their legal obligations, which may include making a suspicious activity report under the money-laundering rules. Continuing to act could make the adviser complicit.
8Which UK body is responsible for the administration and collection of the main taxes such as income tax, corporation tax and VAT?
A.The Bank of England
B.HM Revenue & Customs (HMRC)
C.The Financial Conduct Authority
D.Companies House
Explanation: HM Revenue & Customs (HMRC) is the UK government department responsible for administering and collecting most taxes, including income tax, National Insurance, corporation tax, capital gains tax and VAT.
9Which of the following is an indirect tax?
A.Income tax
B.Corporation tax
C.Value added tax (VAT)
D.Capital gains tax
Explanation: VAT is an indirect tax because it is charged on supplies of goods and services and is collected by businesses on behalf of HMRC, rather than being levied directly on a person's income or gains.
10The principle of 'professional competence and due care' requires a member to:
A.Always charge the lowest possible fee
B.Maintain professional knowledge and skill and act diligently in accordance with applicable standards
C.Disclose all client affairs publicly
D.Guarantee a tax refund for every client
Explanation: Professional competence and due care means a member must keep their knowledge and skill at the level required to give competent service and must act diligently and in line with applicable technical and professional standards.

About the ICAEW Principles of Taxation Exam

Principles of Taxation is the Certificate Level tax module of the ICAEW ACA qualification, renamed Tax Fundamentals under the Next Generation ACA from September 2025. It introduces the objectives of taxation and the ethical framework that tax advisers work within, then teaches students to compute the main UK taxes in straightforward scenarios: income tax and National Insurance contributions, capital gains tax, corporation tax and VAT, together with the administration of these taxes through self-assessment. The computer-based exam mixes objective questions (multiple-choice, multi-part, multiple-response and numeric entry) worth around 80% of the marks with two scenario-based questions worth 20%. Relevant rates and allowances are provided in the exam, so the emphasis is on understanding the computation method and the rules rather than memorising every threshold.

Assessment

ICAEW Principles of Taxation Study Tips from Top Performers

1Learn the layout of the income tax computation - non-savings, savings then dividend income, applying allowances and bands in the correct order - because most marks are lost on sequence, not arithmetic.
2Practise corporation tax by always starting from the accounting profit and adjusting: add back disallowable expenses, deduct non-trading income, then deal with capital allowances separately.
3Memorise the National Insurance class map (Class 1 employees, Class 1 and 1A employers, Class 2 and 4 self-employed) so you pick the right class quickly in scenario questions.
4For VAT, get fast at the output-minus-input logic and remember that irrecoverable input VAT (such as on cars and entertaining) cannot be reclaimed.
5Use the rates and tax tables provided in the exam to confirm figures rather than memorising them, and time yourself so the two scenario questions get their fair share of the 90 minutes.
6Drill the administration rules - filing dates, payment dates, payments on account, and penalties - because these are quick marks that many students leave to the last minute.
