Our client is a boutique mid-market M&A and strategic advisory firm dedicated to the technology, media, and telecommunications sectors. Comprised of transaction experts, sector specialists, and chartered accountants, they deliver exceptional outcomes across buy-side advisory, sell-side advisory, and financial due diligence.

We are seeking a technically excellent and commercially aware M&A Tax Advisor to deliver high-quality tax due diligence and M&A tax advice across transactions. This is a standalone consultant role, structured on a project-based, part-time model, and ideally suited to a Senior Manager or equivalent level with strong UK tax expertise and transaction exposure.

The successful candidate will operate as part of a forward-looking, technology-enabled financial due diligence business, but with full autonomy over scoping, executing, and delivering tax due diligence outputs. You will engage directly with clients, produce clear, pragmatic advice, and integrate with the wider deal team on live buy-side and sell-side projects.

This position is inside IR35 to ensure smooth integration with our advisory team. It is initially designed for flexible, part-time engagement in line with client demand, but with scope to expand as deal flow increases and as we grow our tax capability.

Key Responsibilities

• Independently scope, execute, and deliver tax due diligence projects for both buy-side and sell-side clients.
• Prepare red-flag reports that clearly identify, quantify, and prioritise tax risks.
• Draft input into SPAs, including suggested tax warranties, indemnities, and disclosures.
• Lead on follow-up Q&A with target companies and their advisers.
• Provide structuring advice on share versus asset deals, tax attribute preservation, and post-deal considerations.
• Deliver clear, client-facing tax advice, adapting communication style for both technical and non-technical audiences.
• Advise founders and shareholders on capital gains, BADR, EMI, and other deal-specific personal tax issues.
• Collaborate with the financial due diligence team to produce integrated Financial and Tax DD reports.
• Develop and maintain internal templates and tax DD frameworks to support repeatable, scalable project delivery.
• Access support from the non-tax team for data, client coordination, and reporting assistance as required.

Skills & Attributes

• CTA, ACA, or equivalent UK qualification.
• 7–10+ years of relevant UK tax experience, including clear exposure to M&A transactions.
• Strong grounding in corporation tax, VAT, employment taxes, and structuring.
• Proven ability to deliver both red-flag and full-scope tax due diligence independently.
• Excellent written reporting skills and pragmatic verbal advice in business English.
• Comfortable advising both technical and non-technical stakeholders.
• Confident operating independently with variable input and changing deal pace.
• Commitment to quality, discretion, and client-first thinking.
