Tax specialist recruitment

Senior Tax Specialist Search — Big 4, Mid-Tier, Boutique and In-House Corporate Tax

Exec Capital provides senior tax specialist search across the UK tax market. The UK tax specialist senior search market is shaped by four distinct candidate pools that warrant separate practitioner treatment — UK Big 4 tax practices (PwC Tax, KPMG Tax, EY Tax, Deloitte Tax), UK mid-tier tax practices (BDO UK, Forvis Mazars, Grant Thornton UK, RSM UK, Crowe UK, Buzzacott, Saffery, Blick Rothenberg, PKF Littlejohn, Evelyn Partners), UK boutique and specialist tax firms (Andersen LLP UK, Ryan UK, plus tax practices at major UK law firms including Slaughter and May, Macfarlanes, DLA Piper, Fieldfisher, Skadden UK), and UK in-house corporate tax leadership at FTSE 100, FTSE 250, mid-market, PE-backed, and family office firms. Each candidate pool has materially different senior compensation calibration, partnership track expectations, technical specialism, and career path patterns.

Our practice covers UK senior tax specialist appointments across the principal UK tax specialism areas — corporate tax (UK CT compliance and advisory, group tax planning, R&D tax credits at UK and international scale), VAT and indirect tax (UK VAT post-Brexit, complex VAT compliance, customs duties), international tax and transfer pricing (BEPS Pillar 2 effective 1 January 2024 in UK, controlled foreign companies, tax treaty optimization), M&A tax (due diligence, structuring, post-merger integration), employment tax (PAYE, IR35 off-payroll working, share schemes including EMI), private client tax (UK and international HNW tax planning following the non-dom regime abolition effective 6 April 2025), R&D tax credits (UK R&D Expenditure Credit and SME scheme), property tax (SDLT, ATED, capital allowances), and tax disputes and HMRC investigations. Every senior tax mandate is led personally by Adrian Lawrence FCA. For senior CFO appointments at UK tax-qualified contexts including FCA-authorised accountancy and audit firms, see our sister firm FD Capital.

The four UK tax specialist candidate pools

UK tax specialist senior search divides into four distinct candidate pools, each operating with materially different career patterns, compensation structures, and senior progression frameworks.

1. UK Big 4 tax practices

The largest UK tax specialist candidate pool by professional headcount, covering Senior Manager, Director, and Partner-level appointments at the four UK Big 4 tax practices. The cohort includes PwC Tax (the largest UK tax practice by partner count and revenue, covering UK and international tax across all specialism areas), KPMG Tax (UK Big 4 tax practice with major UK and international tax presence), EY Tax (UK Big 4 tax practice), and Deloitte Tax (UK Big 4 tax practice, with UK presence following the EY structural separation reversal in 2023 and the Deloitte global structural changes in progress). UK Big 4 tax practices typically employ 1,500-3,000+ tax professionals across the UK, with senior team structure running Tax Senior Manager, Tax Director, Tax Senior Director (where the firm operates this rank), and Tax Partner.

UK Big 4 tax senior search activity covers Tax Director appointments (typically promotion from Senior Manager rank with 8-12 years post-qualification experience, or lateral move from comparable Big 4 or mid-tier firm), Tax Senior Director appointments (typically 12-15 years post-qualification with UK and international tax track record), and Tax Partner appointments (typically internal promotion from Director rank, occasionally lateral from Big 4 competitor or in-house corporate tax leadership). Compensation calibration at UK Big 4 tax — Tax Senior Manager typical base salary £85k-£115k with bonus 15-25% of base, Tax Director typical base £130k-£180k with bonus 30-60% of base, Tax Partner profit share typically £400k-£800k+ with variation by firm, specialism, client portfolio, and year-on-year firm performance. Tax Partners at the largest UK Big 4 practices in the strongest specialism areas (typically transfer pricing, M&A tax, international tax) can earn materially above the typical band.

2. UK mid-tier tax practices

The UK mid-tier tax practice candidate pool covers Senior Manager, Director, and Partner appointments at the UK mid-tier accountancy firms operating significant tax practices. The cohort includes BDO UK Tax (the largest UK mid-tier accountancy firm by revenue, with major UK tax practice across compliance and advisory), Forvis Mazars (formed by the 2024 international combination of Mazars and Forvis with major UK tax practice), Grant Thornton UK Tax (UK mid-tier tax practice with material UK private equity portfolio company tax practice), RSM UK Tax (UK mid-tier tax practice), Crowe UK Tax, Buzzacott (London-based UK mid-tier with major private client tax practice), Saffery (formerly Saffery Champness, UK mid-tier with major private client and family office tax practice), Blick Rothenberg (London-based UK mid-tier with major private client and entrepreneurial business tax practice), PKF Littlejohn (UK mid-tier accountancy with material tax practice), and Evelyn Partners (formed by the 2022 Tilney-Smith & Williamson merger, with major UK private client tax practice).

UK mid-tier tax practice senior search activity covers Tax Manager and Tax Senior Manager appointments (for early-career to mid-career talent), Tax Director appointments (typical Director rank with 8-15 years post-qualification experience, often transitioning from Big 4 to mid-tier with material commercial responsibility uplift), and Tax Partner appointments (typically internal promotion or lateral move from Big 4 with established client portfolio). Compensation calibration at UK mid-tier tax practices typically below Big 4 at Manager and Director rank but with materially faster Partner promotion velocity — typical UK mid-tier Partner promotion timeline is 8-12 years post-qualification against 12-18 years at Big 4. UK mid-tier Tax Partner profit share typical range £200k-£500k with material variation by firm and specialism.

3. UK boutique and specialist tax firms

The UK boutique and specialist tax firm candidate pool covers senior tax appointments at UK tax boutiques, UK and international tax-specialist firms, and major UK law firm tax practices. The cohort includes Andersen LLP UK (the UK practice of Andersen Tax, a major US-rooted international tax network with UK presence), Ryan UK (UK tax recovery and consulting specialist, US-rooted), and the major UK law firm tax practices including Slaughter and May Tax (UK Magic Circle tax practice), Macfarlanes Tax (UK silver circle tax practice with major private client tax presence), DLA Piper Tax UK, Fieldfisher Tax UK, Travers Smith Tax (UK silver circle tax practice with major private equity tax presence), Mishcon de Reya Tax (UK private client tax practice), Skadden UK Tax (US-rooted UK tax practice), and a UK boutique tax firm community covering specific tax specialisms.

UK boutique and specialist tax firm senior search activity covers senior tax adviser appointments at UK private client boutiques (typically combining UK tax-qualified credentials with UHNW client portfolio management track record), Tax Partner appointments at UK law firms (typically combining UK tax-qualified credentials with UK legal-qualified credentials at solicitor-advocate or barrister rank — UK law firm Tax Partners often hold dual qualifications), and senior in-house tax appointments at UK and international tax network firms. UK law firm Tax Partner compensation operates within UK law firm partnership economics — typical UK Magic Circle Tax Partner profit share £1.5m-£3m+, UK silver circle Tax Partner £600k-£1.5m, UK boutique law firm Tax Partner £300k-£800k.

4. UK in-house corporate tax leadership

The UK in-house corporate tax leadership candidate pool covers senior tax team appointments at FTSE 100, FTSE 250, large mid-market, PE-backed, and family office firms. The principal in-house UK tax senior roles include Group Head of Tax (the senior tax team leadership role at the firm — at FTSE 100 firms typically with 20-50+ tax team headcount across UK and international jurisdictions), Group Tax Director (typically a senior team member supporting the Group Head of Tax at firms with major tax team scale), International Tax Director (with accountability for transfer pricing, CFC compliance, treaty optimization, BEPS Pillar 2 implementation), Transfer Pricing Director (typically a major senior role at firms with material cross-border revenue), VAT and Indirect Tax Director (UK VAT compliance, EU VAT post-Brexit, customs duties), Employment Tax Director (PAYE, IR35 implementation, share scheme administration), M&A Tax Director (deal due diligence, transaction structuring at firms with active acquisition programmes), and Tax Risk and Governance Director.

UK in-house corporate tax senior candidate pool typically combines former Big 4 tax practice candidates (most common path — typical career pattern is Big 4 to in-house at Senior Manager or early Director rank, with progression through in-house ranks), former mid-tier tax practice candidates, and (at the most senior in-house roles) former Big 4 Tax Partners moving in-house at Group Head of Tax level. Compensation calibration at UK in-house corporate tax — FTSE 100 Group Head of Tax typical base £200k-£400k with bonus 30-60% of base plus LTIP equity participation, FTSE 250 Group Head of Tax typical base £150k-£250k with bonus 25-50% of base plus LTIP, mid-market Group Head of Tax typical base £120k-£200k with bonus 20-40% of base. PE-backed firm in-house tax leadership typically operates with material equity participation typical of PE-backed senior team compensation structures.

The UK tax specialism areas

Senior UK tax specialist search briefs typically address specialism specificity at the brief stage. The principal UK tax specialism areas include:

Corporate tax. UK corporate tax compliance and advisory at the firm level — UK CT600 compliance, group tax computation, deferred tax accounting (FRS 102 and IFRS), tax provision for financial reporting, R&D tax credit computation, capital allowances claims, and group tax planning. Senior corporate tax specialist roles typically cover Group Head of Tax at FTSE-listed and mid-market firms, plus Director and Partner appointments at Big 4 and mid-tier tax practices serving corporate clients.

VAT and indirect tax. UK VAT compliance and advisory across UK and EU contexts post-Brexit — UK VAT registration and compliance, complex VAT scenarios (partial exemption, capital goods scheme, group VAT registration, VAT on cross-border services and goods), customs duties, and indirect tax. UK VAT post-Brexit operates with complexity — UK firms with EU customer or supplier exposure typically require UK VAT specialism and (where relevant) EU member state VAT specialism. For dedicated VAT senior search context, see our VAT Specialist Recruitment service.

International tax and transfer pricing. UK and international tax compliance and advisory at multinational firm scale — UK transfer pricing compliance under the OECD Transfer Pricing Guidelines and UK domestic law, controlled foreign company (CFC) compliance, double taxation treaty optimization, BEPS Pillar 2 framework implementation (effective 1 January 2024 in UK with the multinational top-up tax provisions), and UK and international tax structuring. International tax senior roles typically cover International Tax Director and Transfer Pricing Director appointments in-house, plus Director and Partner appointments at Big 4 international tax practices.

M&A tax. UK and international tax aspects of M&A transactions — buy-side and sell-side tax due diligence, transaction tax structuring, post-merger tax integration, tax warranty and indemnity advisory. M&A tax senior roles typically cover M&A Tax Director appointments at Big 4 tax practices (the principal candidate pool for senior M&A tax roles), in-house M&A Tax Director appointments at acquisitive UK firms, and Tax Partner appointments at UK and international law firm tax practices supporting M&A advisory.

Employment tax and reward. UK employment tax compliance and advisory — PAYE compliance, IR35 off-payroll working framework (which has materially elevated employment tax senior search activity post the April 2021 private sector IR35 reform implementation), share scheme advisory (EMI for SMEs, CSOP, SIP, SAYE for larger firms, plus bespoke share plan design), employment-related securities, salary sacrifice arrangements, and reward strategy advisory. Employment tax senior roles typically cover Employment Tax Director appointments in-house and Director and Partner appointments at Big 4 and mid-tier tax practices.

Private client tax. UK and international tax planning for HNW and UHNW individuals and family offices — UK income tax, capital gains tax, inheritance tax, trust taxation, UK and international residence and domicile planning (with material reform impact following the non-dom regime abolition effective 6 April 2025), and UK private client tax compliance. Private client tax senior roles typically cover Tax Partner appointments at UK private client boutiques (Buzzacott, Saffery, Blick Rothenberg, Evelyn Partners, plus the broader UK private client boutique cohort), Tax Partner appointments at UK law firms with major private client tax practice (Macfarlanes, Mishcon de Reya, plus the broader UK private client law firm cohort), and Group Head of Tax appointments at UK family offices and family office advisory firms.

R&D tax credits. UK Research and Development tax relief — the UK R&D Expenditure Credit (RDEC) historically for large companies, the UK SME R&D scheme historically for SMEs, and the merged R&D scheme effective for accounting periods beginning on or after 1 April 2024. UK R&D tax credit senior search activity has been elevated through 2023-2024 reflecting the UK R&D regime reform and the elevated HMRC scrutiny of UK R&D claims that has prompted UK firms to recalibrate R&D tax claim strategy. R&D tax senior roles typically cover R&D Tax Director appointments at specialist UK R&D tax firms and major Big 4 R&D tax practices.

Property tax. UK property tax compliance and advisory — Stamp Duty Land Tax (SDLT) including SDLT surcharge structures, Annual Tax on Enveloped Dwellings (ATED), capital allowances on UK property holdings, and UK Real Estate Investment Trust (REIT) tax framework. Property tax senior roles typically cover Director and Partner appointments at Big 4 and mid-tier tax practices serving UK property and real estate clients, plus in-house Tax Director appointments at UK REITs and major UK property firms.

Tax disputes and HMRC investigations. UK tax dispute resolution — HMRC enquiries and investigations, Code of Practice 9 (COP9) cases, tax tribunal litigation, and tax dispute negotiation. UK tax disputes senior search activity has elevated reflecting elevated HMRC compliance activity and UK tax tribunal case law development. Tax disputes senior roles typically cover Director and Partner appointments at Big 4 tax disputes practices and tax-specialist UK law firms (with material UK and Crown Office contentious tax practice).

The UK tax framework reform velocity — what senior candidates need to demonstrate

BEPS Pillar 2 framework. The OECD/G20 Inclusive Framework on BEPS Pillar 2 framework introduces a 15% global minimum tax for multinational firms with consolidated group revenue above EUR 750 million. The UK implemented Pillar 2 through Finance (No 2) Act 2023 with the multinational top-up tax (MTT) and domestic top-up tax (DTT) provisions effective for accounting periods beginning on or after 31 December 2023 (effectively 1 January 2024 for most calendar-year firms). UK in-house tax leadership at affected multinational firms operates against the Pillar 2 framework — Group Head of Tax appointments at Pillar 2 affected firms typically address Pillar 2 implementation track record explicitly at brief stage. For UK regulatory framework context, see UK Government BEPS Pillar 2 implementation guidance.

UK non-domiciled tax regime abolition (April 2025). The UK non-domiciled tax regime — historically allowing UK-resident non-domiciled individuals to elect for the remittance basis of taxation on foreign income and gains — was abolished with effect from 6 April 2025. The new four-year foreign income and gains (FIG) regime applies for individuals arriving in UK after 10 years of non-UK residence. The abolition has material implications across UK private client tax practice, UK family office tax practice, UK international wealth management, and the broader UK HNW and UHNW client market. UK private client tax senior candidates typically demonstrate non-dom abolition advisory track record explicitly at brief stage.

R&D tax credit regime reform. UK R&D tax credit regime materially reformed through 2023-2024 — the merged R&D scheme effective for accounting periods beginning on or after 1 April 2024 replaces the historic split of RDEC for large companies and SME R&D scheme for SMEs. The reform also introduces the new R&D-intensive SME scheme. The reform has been accompanied by elevated HMRC scrutiny of UK R&D tax credit claims, with enquiry volume and reduction in R&D claim approval rates. R&D tax senior candidates demonstrate the reform fluency explicitly at brief stage.

UK private school VAT (effective January 2025). UK private school VAT was introduced effective 1 January 2025, with material implications across UK private school finance and UK private school tax compliance. UK independent school finance teams have built tax capability in response — typical UK independent schools have engaged tax advisory support to navigate the new framework.

UK National Insurance Contributions employer rate changes. UK Employer National Insurance Contributions rate increased from 13.8% to 15% with effect from April 2025, with the secondary threshold reduced from £9,100 to £5,000. The NIC reform has material implications across UK reward strategy and UK employment tax practice — UK firms have actively recalibrated reward design in response.

UK IR35 off-payroll working framework. UK IR35 framework reforms effective April 2017 (public sector) and April 2021 (private sector) shifted IR35 status determination accountability from contractor to engaging firm at medium and large UK firms. UK employment tax senior candidates demonstrate IR35 implementation fluency at brief stage. For UK regulatory framework context, see UK Government IR35 guidance.

UK tax specialist professional bodies and qualifications

UK tax specialist senior candidates typically hold one or more professional tax qualifications. The principal UK tax professional bodies include the Chartered Institute of Taxation (CIOT — the UK’s professional body for tax practitioners, with the Chartered Tax Adviser CTA designation as the principal UK tax professional qualification), the Association of Taxation Technicians (ATT — the UK professional body for tax compliance practitioners, with the ATT designation), the Society of Trust and Estate Practitioners (STEP — the UK and international professional body for trust and estate practitioners with material tax dimension, particularly relevant for private client tax), and the Institute of Chartered Accountants in England and Wales (ICAEW — the UK chartered accountancy body with material tax-qualified member cohort, including ICAEW Tax Faculty membership), the Institute of Chartered Accountants of Scotland (ICAS), and the Association of Chartered Certified Accountants (ACCA) with tax-qualified members.

UK tax specialist senior candidates at the most senior levels typically hold combinations of UK accountancy qualifications (ACA, ACCA, CIMA, ICAS) and UK tax qualifications (CTA, ATT). UK law firm Tax Partners typically hold UK legal qualifications (Solicitor, Barrister) plus UK tax qualifications. UK private client tax senior candidates often hold STEP qualifications alongside UK tax-qualified credentials. For UK regulatory framework context, see Chartered Institute of Taxation, Association of Taxation Technicians, and STEP.
