US/UK Tax Assistant Manager

US/UK TAX ASSISTANT MANAGER - LONDON (£55,000 - £70,000)

Established US/UK Tax Boutique | London

First Management Role in a Technically Demanding Environment

We are looking for an Assistant Manager to step up into team leadership at a long-established, specialist US/UK tax practice. You will manage complex client work, develop junior staff, and gain real exposure to high-level advisory matters in a boutique where technical credibility matters far more than volume.

What You'll Do:

• Lead a small team handling complex expatriate tax matters.

• Review and sign off US and UK tax returns.

• Manage technically demanding client files (PFIC, CFC, expatriation, foreign tax credits).

• Contribute to cross-border tax planning and advisory projects.

• Mentor junior staff and support their ongoing technical development.

• Liaise with clients and tax authorities on complex matters.

What You Need:

• ATT qualified and/or IRS Enrolled Agent (essential); CTA study or qualification is a strong plus.

• 4-6 years' US/UK personal tax experience with proven technical depth.

• Track record handling complex cross-border matters.

• Team leadership experience or proven readiness to step up into management.

• Strong technical credibility across dual-handling work and excellent client-facing skills.

Why This Firm Is Different:

• Established Reputation: Recognised specialist practice in US expatriate taxation with decades of market presence.

• Technical Rigour: Leadership team includes highly experienced Directors holding ATT, CTA, and EA qualifications.

• Complex Work Focus: High-net-worth clients, intricate cross-border structures, and advisory-led engagements rather than assembly-line compliance.

• Boutique Environment: Genuine client portfolio ownership and direct exposure to senior partners.

• Specialist Niche: The ideal setup if you want to build a reputation as a true subject-matter expert in US/UK cross-border tax.

Salary & Benefits: £55,000 - £70,000 + Benefits
