Tax Avoidance, Tax Evasion and Acceptable Planning for ACCA ATX

Updated 11 October 2026 · Fact-checked

Tax evasion is illegal: you hide income or lie to HMRC. Tax avoidance uses the law in ways Parliament did not intend, and the GAAR can counter it. Acceptable tax planning uses reliefs as intended. In ATX you classify the measure, test it against the client's objectives, then advise on risk.

Understand Tax Avoidance, Tax Evasion and Acceptable Planning

Start with the legal line. Tax evasion is deliberately hiding income, gains or facts, or giving false information, to pay less tax than the law requires. It is a crime. Examples are leaving cash takings out of the accounts or not declaring rental income.

Tax planning (also called tax mitigation) means arranging your affairs to use reliefs, exemptions and rates in the way the legislation intended. Using an ISA, making pension contributions, or giving assets away to use the nil rate band are all acceptable. The client really does what the law encourages.

Tax avoidance sits in between. The arrangement is not hidden and may technically comply with the wording of the law. But it is designed to get a tax advantage that Parliament did not intend, often through artificial steps with no commercial purpose. It is not a crime, but it can be defeated. The UK's General Anti-Abuse Rule (GAAR) lets HMRC counteract tax advantages from abusive arrangements. An arrangement is abusive if it cannot reasonably be regarded as a reasonable course of action in relation to the relevant tax provisions. Think of a spectrum: acceptable planning, then aggressive avoidance, then evasion.

In ATX the question is rarely just 'which category is this?'. You are usually asked to advise whether a measure is appropriate for a particular client. A measure can be legal and still be wrong for the client. It may conflict with their objectives, be too costly or complex, tie up cash, carry a reputational risk, or rely on the client's circumstances staying the same. Always link the measure to the client's facts.

You must also think as a professional. Under the ACCA Code of Ethics and professional conduct in relation to taxation guidance, you must not assist evasion, and you should be cautious about aggressive schemes. Where a client will not correct a known error or disclose income, you consider your duties, which can include ceasing to act. Marks for professional skills reward scepticism, balanced judgement and clear communication.

Key rules to remember

Tax evasion: Evasion = deliberate non-disclosure or misstatement to HMRC → illegal; The key words are deliberate and hiding or lying. Penalties and prosecution can follow.
Tax planning (mitigation): Planning = using reliefs and exemptions as Parliament intended → acceptable; The client's real actions match the purpose of the relief, for example a genuine ISA subscription or pension contribution.
Tax avoidance: Avoidance = within the letter of the law, against its spirit → legal but open to challenge; Look for artificial steps, no commercial purpose, and a result Parliament did not intend.
GAAR test: Tax arrangement + tax advantage + abusive (not a reasonable course of action) → advantage can be counteracted; The GAAR targets abusive arrangements only. It is not aimed at ordinary, sensible planning.
Appropriateness test: Appropriate = legal and intended + meets client objectives + acceptable risk, cost and cash flow; A measure that saves tax but fails the client's wider aims is not appropriate.

How to solve Tax Avoidance, Tax Evasion and Acceptable Planning questions

Use this approach for any question asking you to assess or advise on a tax saving measure.

1Read the requirement and note the client, their objectives (for example cash needs, control, family, reputation) and any constraints.
2Identify what the measure actually does. State the tax advantage it aims to get.
3Classify it: is it planning as intended, avoidance with artificial steps or no commercial purpose, or evasion (concealment or false statements)?
4If it looks like avoidance, discuss the GAAR, and mention disclosure rules if relevant. Explain that HMRC could counteract the advantage and that penalties may follow.
5Test it against the client's circumstances. Consider liquidity, control, other taxes, timing, cost, complexity and reputation.
6Quantify the saving if figures are given, using the tax rates provided. Compare it with the risks and costs.
7Give a clear recommendation, offering an alternative measure where the first is not suitable.
8Add the professional point: if evasion is involved, say you cannot assist, and explain the steps you would take.

Quickest way: Three-question filter

When to use it: Use it when time is short and you must give a view on a measure in a few minutes.

Is anything hidden or false? If yes, it is evasion: say it is illegal and you cannot act.
Does the client really do what the relief was meant to encourage, with a genuine commercial reason? If yes, it is acceptable planning.
If not, it is avoidance: flag the GAAR, the risk of challenge and penalties, then say what you would advise instead.
Finish with one sentence linking the conclusion to the client's objectives.

Common mistakes in Tax Avoidance, Tax Evasion and Acceptable Planning

Treating avoidance and evasion as the same thing.
Both reduce tax and are often described loosely as dodging tax.
Fix: State that evasion is illegal and involves concealment or false statements. Avoidance is legal but may be counteracted.
Saying any tax saving is unacceptable.
Students overreact to the word avoidance and ignore ordinary planning.
Fix: Explain that using reliefs as intended is legitimate. The GAAR targets only abusive arrangements.
Describing the GAAR as a rule that bans all avoidance.
The name sounds broad and students do not recall the abuse test.
Fix: Say it applies where arrangements are abusive, meaning they cannot reasonably be regarded as a reasonable course of action. The advantage is counteracted.
Judging a measure only on whether it is legal.
Students stop at the technical rule and ignore the client.
Fix: Always test against the client's objectives, cash flow, control, risk and reputation.
Ignoring professional ethics when a client conceals income.
The scenario looks like a pure tax question.
Fix: Add that you cannot assist evasion, should encourage disclosure, and may need to consider ceasing to act. Keep confidentiality in mind.
Giving a list of points without applying them to the scenario.
Learned theory is written out rather than used.
Fix: Quote the client's facts in each point and reach a clear recommendation.

Worked examples

Example 1

Aisha, an additional rate taxpayer, wants to pay £20,000 into a registered pension scheme and also asks whether she can leave out £8,000 of cash rental income from her tax return because 'HMRC will never know'. Classify each action and advise her.

Show the solution

Pension contribution: a registered pension scheme is a relief Parliament intends people to use. Aisha is really saving for retirement, so this is acceptable tax planning.
Check suitability: she should consider whether the contribution fits within her annual allowance and whether she can afford to lock money away until retirement age.
Omitting rental income: she knows the income exists and plans to hide it. This is deliberate non-disclosure, so it is tax evasion and a criminal offence.
Consequences: she could face tax, interest on the underpaid tax at the rate provided, penalties and possible prosecution.
Professional advice: I cannot assist with leaving out the income. I should advise her to declare it. If she refuses, I would consider my ethical duties, including ceasing to act, and the rules on confidentiality and disclosure.

Answer: The pension contribution is acceptable planning, subject to the annual allowance and Aisha's liquidity. Omitting the rent is tax evasion. It must be declared, and I cannot act if she refuses.

Example 2

Raj owns a profitable trading company. An adviser proposes a series of circular transfers between connected companies with no commercial purpose, solely to create a deductible loss of £300,000. Advise Raj whether to proceed.

Show the solution

Identify the advantage: a deduction (and so corporation tax saving) with no real economic loss.
Classify: nothing is hidden, so it is not evasion. But the steps are artificial, have no commercial purpose and give a result Parliament did not intend. This is aggressive tax avoidance.
GAAR: HMRC could argue the arrangement is abusive because it cannot reasonably be regarded as a reasonable course of action in relation to the relevant tax rules. If so, the tax advantage can be counteracted.
Tax at stake: the possible saving at the main rate of 25% on £300,000 is £75,000 (£300,000 × 25%). This is for an assumed profit above the upper limit of £250,000. Marginal relief would alter this if profits were lower.
Client circumstances: Raj has a genuine trading business, so he risks reputational damage, adviser fees, an HMRC enquiry, interest on any tax later due, and possible penalties.
Alternative: use genuine planning, such as capital allowances on real investment (the annual investment allowance limit is £1,000,000) or pension contributions for directors, which give relief as intended.
Recommendation: do not proceed with the circular transfers.

Answer: The scheme is aggressive avoidance, not evasion. The potential £75,000 saving is at risk from the GAAR, plus interest, penalties and reputational harm. Raj should not proceed and should use genuine reliefs such as capital allowances instead.

Exam tips

Define the three terms in one line each, then spend most of your time applying them. Marks go to application.
Always link your conclusion to the client's stated objectives. A legal measure can still be inappropriate.
When you discuss the GAAR, say what it needs: arrangements that are abusive and give a tax advantage. Do not say it bans all avoidance.
Where concealment appears in the scenario, add the ethical response. This earns professional skills marks.
Use the rates in the tax tables given and show workings when you quantify a saving.

Tax Avoidance, Tax Evasion and Acceptable Planning: frequently asked questions

What is the difference between tax avoidance and tax evasion for ATX-UK?

Tax evasion is illegal. It involves hiding income or giving false information to HMRC. Tax avoidance is legal on the wording of the law but goes against its intended purpose, and HMRC can counteract it.

What is the GAAR and when does it apply?

The General Anti-Abuse Rule lets HMRC counteract tax advantages from abusive arrangements. An arrangement is abusive if it cannot reasonably be regarded as a reasonable course of action in relation to the relevant tax rules. Ordinary planning that uses reliefs as intended is not targeted.

Is tax planning the same as tax avoidance?

No. Tax planning, or mitigation, uses reliefs and exemptions as Parliament intended, such as ISAs or pension contributions. Avoidance uses artificial arrangements to get an advantage Parliament did not intend.

How should I advise a client who wants an aggressive scheme?

Explain the GAAR risk, the possible interest and penalties, and the reputational and cost issues. Test it against their objectives and suggest a genuine alternative. State clearly that you cannot support evasion.
