Us Tax Manager

At Sopher + Co, we've spent more than 50 years helping entrepreneurs and high-net-worth individuals navigate complex financial and commercial challenges. From tax planning and private office services to business advisory and technology, we bring everything together to make life simpler and help our clients focus on what matters most.

We don't just solve problems. We build relationships, offer clarity, and give our clients the confidence to move forward. And it's our people who make that possible.

We started in Elstree in 1975, working closely with clients in the media, entertainment and music industries. Today, we support a diverse and prestigious client base across more than 20 sectors, with a continued strong and long-standing presence in entertainment and media. While we've grown, our approach hasn't changed. We keep things straightforward and focus on advice that is practical, personal, and easy to act on.

If something's complex, we simplify it. That's where we add value.

Your clients include US citizens and green card holders living in the UK, UK residents with US income or assets, internationally mobile executives, entrepreneurs, and clients from our long-standing entertainment and media base with earnings in both countries.

• Help clients bring their US filings up to date, including under the IRS Streamlined Filing Compliance Procedures.

• Own the financial management of your engagements, including budgets, WIP, billing, recoveries and cash collection.
• Support marketing events and business development, and build your network with lawyers, wealth managers and family offices.

• Manage and develop assistant managers, seniors and juniors, and take an active role in the annual appraisal process.
