How to pass your ACCA Advanced Taxation exam. Straight talk from Ireland's leading ATX expert

If you're sitting the Advanced Taxation (ATX) paper there's a good chance you already know it's one of the more demanding papers at Strategic Professional level. Two sittings a year. Two distinct papers. And an examiner who, as our own Paula Byrne puts it, writes a beautifully crafted exam question where not a single sentence is wasted.

Paula recently delivered a live webinar exclusively for students studying the Irish ATX variant, covering everything from general exam approach to a deep dive on the December 2025 paper. We've pulled together the key takeaways below, but honestly, you'll want to watch the full recording. It's well worth the hour.

The single most important thing: know your conditions

Paula is emphatic on this. If you take one thing from the webinar, it's that you need to know the conditions of your tax reliefs off by heart, every single one of them. Not three out of five. All five.

Why? Because the examiner builds his questions around those conditions. He drops clues, a taxpayer's age, their shareholding percentage, their residency status, and if you know your conditions cold, you'll immediately recognise what relief is in play. If you don't, you're flying blind.

"...by knowing your conditions, you can spot in the exam question what is he asking you? For example, he might say somebody is aged 55. So you might think, okay, so this might be a retirement relief question. Without you knowing your conditions off by heart, you won't be able to spot the steer, and indeed you won't be able to answer the question" — Paula Byrne

The examiner's own report flagged this directly, students didn't know all their conditions. He said it twice. Know your clawback periods too. Telling a client they qualify for retirement relief but failing to mention the six-year clawback isn't good enough advice, and it won't be good enough in the exam either.

Professional marks: the examiner has gone to town on these
 

There are 20 professional marks across the paper, and they're no longer confined to question one. Commercial acumen in particular has become a much bigger feature of recent papers, and the December 2025 sitting leaned into it heavily.

Commercial acumen essentially means two things: giving unsolicited advice, and thinking about what something will cost. It's the kind of thing you probably do naturally when talking to someone about their finances, flagging something useful even when nobody asked.

What good commercial acumen looks like in practice:

• Alert the client to the six-year clawback on retirement relief, even if they didn't ask
• Flag that they've already used part of their lifetime threshold
• Point out they might only need to wait one more year to qualify for a relief
• Raise the cost implications of taking on a conflicting client, the "Chinese wall" scenario

Ethics carries five marks and will appear in question one. Paula's memory aid: think Wolf of Wall Street and cold-calling. I = Integrity, O = Objectivity, C = Competence, C = Confidentiality, P = Professional behaviour. Anti-money laundering ties into the ethics section too, so don't neglect it.

Paula mentions a specific ACCA ethics podcast available on HERE, if you listen to it, she says, there's no ethics question you won't be able to answer.

Time is not your friend. Plan before you go in

You have 195 minutes and three compulsory questions. At 2.4 minutes per technical mark, time management has to be decided in advance, not on the day. Research consistently shows you pick up more marks at the start of a question than at the end, so don't chase the last mark. Move on.

Question one can be a trap for students who over-invest in it. Paula's suggestion: consider leaving it until last. And whichever response option you use, word processor, spreadsheet, or both — make sure it's a deliberate choice based on what you've practised, not a panicked decision in the exam hall.

For question one, communication marks require a letter, email, or memorandum written in the word processor. Your calculations go in the spreadsheet function, with the results referenced back into your written answer. For questions two and three, the choice is yours, use whatever format you've practised and can execute within the time.

How to spot the "steers" in the question

The examiner writes with intention. Every detail in the case study is there for a reason. Paula's advice is to treat each piece of information as a clue:

• Taxpayer's age — points toward a specific relief (retirement relief, young trained farmer, dwelling house)
• Shareholding percentages — likely a close company or share buyback question
• Non-domiciled but Irish resident — residency question; think remittance basis
• List of errors in tax returns — revenue audit
• Shareholders not getting along — share buyback
• Two taxpayers in similar circumstances — usually one qualifies for a relief and one doesn't

You can only spot these steers if you know your conditions inside out. That's why it always comes back to the same point.

A note on Finance Act 2024

Finance Act 2024 is the examinable legislation, and it covers you for the June and December sittings this year — and the June sitting next year as well. This is worth knowing if you don't get through first time: you won't need to relearn a new Finance Act for the following sitting. That said, if you're working from older materials, update them now. The advice in older solutions may not reflect the current legislation.

Watch the full webinar

The recording covers Paula's full walkthrough of the December 2025 paper, including how she reads the case study for steers, how she structures the answer to question one, and how to handle the ethics and commercial acumen components. It's the closest thing to sitting beside Ireland's most experienced ATX lecturer for an hour — and it's free.
