US Senior Tax Manager - Single Family Office

US Tax Advisor – Single Family Office

Location: London (with flexibility)

Level: Experienced Manager to Senior Manager (or equivalent)

Specialism: US Corporate & Private Client Tax – Mid-Market Focus

We are partnering with a substantial single-family office representing a family with significant global investments, including a major stake in a hedge fund alongside private structures, SPVs, and diverse asset holdings. With a growing number of family members preparing to relocate to the US & vice versa, this is a unique opportunity to be the in-house eyes and ears on all things US tax.

The Role

We are seeking an experienced US Tax Advisor with a career dedicated to US tax – so no UK tax work involved. You will advise on a wide range of matters for both individuals and corporates, including:

• Corporate, personal, and partnership tax
• Planning for family members moving to the US
• Structuring and advisory work across SPVs and private investments
• Liaising with external advisors to ensure efficient tax outcomes
• Reviewing K-1s, identifying relevant matters for escalation, and ensuring smooth tax compliance processes
• Modelling transactions, preparing analysis in spreadsheets, and delivering recommendations in clear, concise presentations

This role offers exposure to a breadth of work in a fast-paced, high-value environment, with significant autonomy and the opportunity to contribute to strategic decision-making.

What We're Looking For

• US-trained tax professional preferred, although we will consider UK-trained candidates who have moved into a US tax role
• 4-8 years post-qualification experience (Experienced Manager to Senior Manager level) – NB as with most family office roles / firm they offer a flat structure
• A mixed US tax background (corporate + private client) ideal; if specialism is required, preference is for private client with partnership expertise
• Proven ability to work self-sufficiently in an in-house environment- this is not a siloed advisory role; you'll be hands-on with the detail and the abilty to work cross fucntionally and globally.
• Strong track record in advisory work rather than purely process-driven compliance
• CPA (or US equivalent) preferred; enrolled agents with relevant depth of experience also considered
• Hedge fund, asset management, real estate, or crypto exposure would be a bonus, but is not required

Why Join?

• Be part of a sizable, collaborative tax team within a prestigious single-family office
• Work on varied, complex, and high-value matters spanning corporate and personal US tax
• Operate at the intersection of technical tax and strategic business planning
• Enjoy a flat, non-hierarchical culture with direct engagement at senior levels
• Play a key role in an environment where your advice has immediate, tangible impact

This is an exciting opportunity for a seasoned US tax professional seeking variety, autonomy, and the chance to work closely with ultra-high-net-worth clients and their businesses in a genuinely collaborative setting.
