The Senior Corporate Tax Manager brief has changed materially since the OECD’s Pillar Two global minimum tax came into effect in the UK from 1 January 2024. The skills that defined the role before Pillar Two — UK corporation tax compliance, tax accounting under FRS 102 or IFRS, management of the external audit of the tax charge, relationship management with HMRC — remain essential. But the additional capability now required to manage Pillar Two compliance has narrowed the candidate pool and raised the specification for what a strong Senior Corporate Tax Manager needs to know.

This piece explains what Pillar Two requires of the in-house corporate tax team, what additional skills employers are specifying, and what the candidate market looks like for Senior Corporate Tax Manager appointments in 2026.

What Pillar Two Actually Requires of the In-House Tax Team

The OECD Pillar Two Global Anti-Base Erosion Rules (GloBE) require UK-headquartered multinationals with consolidated revenue above €750 million to calculate a top-up tax for any constituent entity in any jurisdiction where the effective tax rate is below 15%. The UK has implemented these rules through the Multinational Top-up Tax (MTT) and the Domestic Top-up Tax (DTT), both effective from 1 January 2024.

The calculation requires the in-house tax team to produce jurisdiction-by-jurisdiction effective tax rate calculations based on GloBE income, which is derived from the consolidated financial statements but adjusted for a significant number of specific GloBE adjustments. The data requirements are extensive: the team needs jurisdiction-level profit and loss and tax charge data at a level of granularity that many group reporting processes were not designed to produce.

In practice, this means the Senior Corporate Tax Manager at an in-scope group needs three capabilities that were not standard in the role before 2024: the ability to interpret and apply the HMRC MTT/DTT guidance, the ability to work with financial data at entity and jurisdiction level to produce the GloBE calculations, and the project management capability to coordinate the Pillar Two compliance process across a complex group structure.

What Employers Are Specifying

The Senior Corporate Tax Manager briefs we are receiving in 2026 for groups within Pillar Two scope reflect the additional requirements. The most common additions to the specification since 2023 are:

Pillar Two awareness or experience. Employers are distinguishing between candidates who have theoretical knowledge of the GloBE rules and candidates who have been directly involved in a Pillar Two compliance process — either preparing the group’s MTT return, managing the Safe Harbour analysis, or working with the external advisers who prepared the first-year Pillar Two filings. The latter are in significantly shorter supply.

Data and systems capability. The Pillar Two data requirements have accelerated the demand for corporate tax managers who can work with ERP systems, data extraction tools and Excel at an advanced level. The manual data gathering process that many groups used for their first Pillar Two filing is not sustainable at scale, and employers are specifying candidates who can help build more efficient data processes.

Tax accounting depth. The interaction between Pillar Two and current tax and deferred tax accounting under IAS 12 or FRS 102 is complex and the subject of ongoing IASB guidance. Senior Corporate Tax Managers who can manage the tax accounting implications of Pillar Two — including the specific IAS 12 amendment that temporarily exempts deferred tax relating to Pillar Two from recognition — are in demand.

The Candidate Market in 2026

The market for Senior Corporate Tax Managers in 2026 is characterised by strong demand and a candidate pool that has not expanded as fast as the specification has risen. The addition of Pillar Two to the already-demanding corporate tax manager specification — UK compliance, tax accounting, transfer pricing awareness, HMRC relationship management — has created a genuine skills shortage at the senior manager level in corporate tax.

Salary ranges reflect this. Senior Corporate Tax Managers with Pillar Two experience at in-scope groups are achieving salaries at the top of or above the standard range for the role — typically £85,000 to £110,000 in London, £75,000 to £95,000 outside London — with employers who need the capability quickly willing to move above those ranges to secure the right candidate.

Candidates who have been directly involved in Pillar Two compliance at a previous employer should ensure their CV makes this explicit — the experience is in demand and should be highlighted prominently rather than buried in a list of responsibilities. For employers briefing a Senior Corporate Tax Manager search, Accountancy Capital Senior Corporate Tax Manager Recruitment covers the current candidate market and the briefing process in detail.

What to Prioritise in the Interview

For employers interviewing Senior Corporate Tax Manager candidates with Pillar Two experience, the most diagnostic interview question is: describe the Pillar Two compliance process at your current employer — who is responsible for what, what data sources are used for the GloBE calculations, and what has been the biggest challenge in year one? A candidate who has genuinely owned or co-owned the process can answer this in specific operational detail. A candidate who has had peripheral involvement will give a more generic answer about the rules.
