“Tax manager” is one of the least useful phrases in a job specification. It describes at least four distinct disciplines with different technical demands, different candidate pools, different scarcity premiums and different failure modes — and a business that advertises for one and interviews for another will fill the role competently and regret it within a year.
This is a guide to what actually separates them, what genuinely transfers between them, and how to specify a tax hire so the shortlist contains people who can do the job you have rather than a job adjacent to it.
Why the distinction matters more in tax than elsewhere
In most finance disciplines, adjacent experience is a reasonable substitute. A management accountant from manufacturing can learn services; a financial controller from a £20m business can run a £40m one. The technical core travels.
Tax does not work like that, for two reasons.
The legislation is genuinely different. Corporate tax, VAT, personal tax and disputes draw on separate bodies of law that interact but do not overlap. Someone excellent at corporation tax computations has no particular advantage in a partial exemption calculation.
And the work has different shapes. Compliance is cyclical and deadline-driven. Advisory is episodic and judgement-heavy. Disputes are adversarial and unpredictable. People who thrive in one frequently dislike another, and that shows up as attrition rather than as poor performance.
1. Corporate tax: the largest pool and the widest range
The discipline most people mean when they say “tax manager”, and the one with the deepest candidate pool.
What the role covers: corporation tax computations and returns, group relief and consolidation, deferred tax for the financial statements, capital allowances, and increasingly the international dimension — transfer pricing, Pillar Two, and the reporting that follows.
The split that matters when specifying: compliance-weighted or advisory-weighted. A compliance-weighted role is cyclical, deadline-driven and well suited to someone who wants a defined annual rhythm. An advisory-weighted role is episodic and judgement-heavy — structuring, transactions, group reorganisations. Both are legitimate; specifying one and delivering the other is the commonest reason these appointments turn over.
Where employers go wrong: requiring CTA as essential on a compliance-weighted role. It narrows a competitive pool for a signal you do not need, and it prices the role higher than it has to be.

2. VAT: the scarcest transfer and the best-paid
Indirect tax is a genuinely different specialism, and the one where in-house demand most exceeds supply.
What the role covers: VAT returns and the reconciliations behind them, partial exemption where the business has exempt supplies, place-of-supply analysis for international trade, the treatment of complex transactions, and — increasingly — the systems and data work that Making Tax Digital has made unavoidable.
Why the pool is thin: most accountants encounter VAT as an adjacent obligation rather than a specialism, so genuine depth is acquired only by people who have chosen it. That scarcity is real and it prices accordingly — VAT specialists command a premium over corporate tax at equivalent seniority in most in-house markets.
What employers underestimate: the systems dimension. A VAT manager who cannot interrogate the underlying transaction data is dependent on whatever the ERP produces, and the errors that matter are usually in the data rather than the analysis.

3. Private client: plenty of supply, very little in-house demand
The discipline with the most awkward market structure, and the one where career advice most often goes wrong.
What the role covers: self-assessment for individuals, partnerships and trusts, capital gains, inheritance tax and estate planning, residence and domicile questions, and the extraction and structuring decisions facing owner-managed business shareholders.
The structural point: almost all private client work sits in accountancy practice, because most businesses have no personal tax obligations. The in-house market is genuinely small — family offices, wealth managers, and owner-managed businesses where the corporate and personal positions are entangled. Practitioners planning a move in-house should understand that early rather than discover it.
The seasonal reality: the self-assessment deadline removes private client specialists from the recruitment market entirely for the first month of the year. Searches launched in December stall. Recruit October to November, or from February onward.

4. Investigations: the smallest pool and the highest stakes
The specialism nobody writes about and the one where hiring badly costs the most.
What the role covers: managing HMRC enquiries from the opening letter to settlement, making and framing disclosures, quantifying exposure, and negotiating penalty mitigation and behaviour classification.
What makes it different: the technical position is rarely the hard part. The hard part is scope control — knowing what to provide and what to push back on, recognising an expanding enquiry before it expands, and understanding what is actually reportable. None of that is in the legislation, and it cannot be reasoned from first principles.
The candidate pool includes people from outside accountancy. Some of the strongest investigations specialists are ex-HMRC, and many hold no accountancy qualification at all. Writing “qualified accountant essential” into the specification removes them.
And most businesses should buy rather than hire. Unless exposure is recurring — more than one enquiry in three years, or a sector under sustained attention — a specialist firm or an interim for the duration of a case is the proportionate answer. Our page on tax investigations recruitment sets out when in-house capability is genuinely justified.
What actually transfers
Having drawn the distinctions, it is worth being clear about the common ground, because employers over-correct in both directions.
Transfers well: the habit of documenting a position contemporaneously; the judgement about what is worth escalating; the ability to explain a technical position to someone who is not a specialist; and relationship management with HMRC and external advisers. These are professional habits rather than technical knowledge, and they are what distinguish a good tax professional in any discipline.
Does not transfer: the legislation, the computational mechanics and the sense of where the risks sit. A corporate tax manager can learn partial exemption — but not while being the firm’s only tax resource, with nobody to check them.
Which gives the practical test for employers: the question is not whether the candidate knows your specific discipline. It is who in your business would notice if they got it wrong. Where there is genuine expertise elsewhere — an engaged adviser, an existing specialist, a technically strong FD — an adjacent candidate with strong professional habits is frequently the better and faster appointment. Where there is not, buy the specific experience.
Specifying a tax role properly
Four things, and most specifications include none of them.
Name the discipline, not “tax”. Corporate, indirect, employment, private client or disputes. This single change transforms the relevance of a shortlist.
State the compliance-advisory split as it will actually be, not as it sounds best. The two attract different people and mismatching them is the commonest cause of early attrition.
Be honest about whether they are alone. A sole in-house tax resource is a materially different job from a role in a team, and the candidates who suit each are different. Some people find the autonomy energising; others find it exposing.
And say what is not working. A position nobody has documented, a claim that has never been reviewed, an enquiry in progress. Good candidates read that as the reason the role exists, and it filters those who want a tidy inheritance.
When to hire and when to buy
A brief word on the decision that precedes the specification, because a good number of businesses hire when they should not.
The honest test is whether the difficult judgements are occasional or continuous. Occasional judgements — an annual compliance cycle, a transaction every few years, a first R&D claim — are better bought from a firm or covered by an interim. Continuous judgement, where the business is making decisions with tax consequences most months, justifies an in-house appointment.
The simplest indicator most businesses ignore: add up what was spent on tax advice last year, and list what nobody currently owns. Those two facts usually make the decision, and quite often they show that the answer is a bounded piece of work rather than a permanent hire.
Accountancy Capital’s tax recruitment practice covers in-house appointments across all four disciplines, permanent and interim.
The question worth asking at interview
One question works across every discipline on this page and it is the most revealing thing you can ask a tax candidate: tell me about a position you declined to take.
Technical knowledge is testable and it is table stakes. What distinguishes a good in-house tax professional is judgement about where the line sits — and judgement shows in what somebody would not do rather than in what they would. Candidates who have genuinely held a position under commercial pressure have an answer, and it is usually specific.
Candidates who have not will tell you about their qualifications.
