Job description

If you're at the stage in your career where you're looking for more than just reviewing returns and hitting deadlines, this could be worth exploring.

I'm working with a nationally recognised public accounting and advisory firm that's continuing to invest heavily in its Commercial Services practice. They're looking for a Tax Senior Manager to help lead client relationships, oversee complex engagements, and play a key role in developing both the team and the practice.

The client portfolio spans a mix of established middle-market businesses and high-growth companies across sectors including Consumer Products, Hospitality, Manufacturing, and Distribution. It's a varied role with plenty of exposure to business owners, executives, and decision-makers.

What you'll be doing

You'll take ownership of a portfolio of clients from planning through delivery, acting as the trusted advisor throughout the engagement. This is a leadership role where you'll balance technical tax expertise with commercial thinking and client management.

Responsibilities include:

• Managing multiple tax engagements from planning through completion.
• Acting as the main point of contact for clients, building long-term trusted relationships.
• Reviewing partnership and corporate tax work while ensuring quality and technical accuracy.
• Advising clients on complex tax matters and providing practical, commercial solutions.
• Leading engagement teams, allocating work, mentoring staff, and supporting their professional development.
• Managing budgets, project timelines, billing, and overall engagement profitability.
• Conducting technical research and communicating findings clearly to clients and internal teams.
• Supporting business development by identifying new opportunities within existing client relationships.

What they're looking for

• 8+ years of public accounting tax experience.
• Strong experience managing client relationships and leading engagement teams.
• Technical expertise across partnership and corporate taxation.
• Confident communicator with the ability to explain complex tax matters in a practical way.
• Strong organisational skills with the ability to manage multiple priorities.
• Experience with leading tax software and Microsoft Office.

This is a firm that gives experienced professionals room to grow. You'll work with a collaborative leadership team, have direct client exposure, and be trusted to make decisions rather than simply execute them.

The position is based in New York with a hybrid working model, offering flexibility while maintaining regular in-person collaboration with colleagues and clients. NO SPONSORSHIP IS AVAILABLE FOR THIS POSITION

If you're looking for a move where you can genuinely influence client relationships, develop people, and continue progressing your career within a respected national firm, I'd be happy to share more details confidentially.
