Tax Investigations Manager

Nationwide Big 4 firm with a London HQ BUT very Hybrid working (1-2 days in office a week) Up to £65,000

A leading Big Four firm is looking for a Tax Investigations Manager to join a specialist disputes team with a national client base and a genuinely flexible working model.

This is a strong move for someone who enjoys HMRC enquiry work, tax investigations and dispute resolution, but wants more autonomy, direct Partner exposure and a better route into commercial client development. The role sits within a high-trust team where people are judged on output, not how often they can be seen near a desk looking professionally exhausted.

As Tax Investigations Manager, you'll work directly with an impressive Partner and support a mix of corporate, owner-managed, private client and family office matters. Based Nationwide, the team has a strong internal network of clients and referrers, giving you the chance to build business development confidence without having to start from a cold market.

\n
• Supporting corporate, entrepreneurial and private wealth clients
\n
• Preparing technical correspondence, reports and settlement recommendations
\n
• Working directly with the Partner on complex cases and client strategy

\n
• Strong written communication and confidence dealing with HMRC
\n

Ex-HMRC candidates will be considered where there is genuine enquiry experience, particularly where you have dealt directly with taxpayers, agents and technical casework.

This Tax Investigations Manager role would suit someone who wants the quality of Big Four work, the flexibility of a national platform, and the chance to grow commercially without losing the technical work that made them good in the first place.

Confidential conversations are welcomed from candidates across Nationwide with tax investigations experience in accountancy, HMRC or specialist advisory work.
