The practical impact of Budget 2026 will unfold beyond Budget Day. Alongside the headline changes, HMRC’s investment in people, technology and information gathering is reshaping how it identifies risks, conducts enquiries and pursues liabilities. For businesses and individuals, understanding that direction of travel is essential to managing costs, protecting cash flow and avoiding unnecessary disruption.

What matters now

• Understand your exposure. Consider how the changes affect your business, existing arrangements and reporting obligations, including when they take effect.
• Keep the evidence. Clear records and documented reasons for tax treatments can make a significant difference when HMRC asks questions.
• Act early. A considered response at the outset of an enquiry can help focus the issues, contain costs and prevent avoidable escalation.
• Protect your position. HMRC’s conclusions are open to challenge. Understanding your rights, the scope of its powers and the relevant deadlines is fundamental to an effective response.
• Keep commercial priorities in view. The right strategy should account for the financial, operational and reputational consequences of a dispute, alongside its legal merits.

Resolve the dispute. Move forward with confidence.

Our Tax Disputes, Investigations and Financial Crime team helps clients navigate every stage of an interaction with HMRC—from initial enquiries and information requests to assessments, penalties, debt recovery and litigation.

We combine technical tax expertise with a practical understanding of the pressures our clients face. We help establish the facts, assess HMRC’s position and develop a clear strategy, whether that involves narrowing an enquiry, negotiating a settlement, pursuing alternative dispute resolution or challenging a decision before the courts and tribunals. Where an investigation carries potential criminal or regulatory consequences, we advise on the response from the outset.

Our focus is on securing the best achievable outcome efficiently, protecting our clients’ interests and enabling them to get on with running their businesses. To discuss how these developments affect you, or any current or anticipated interaction with HMRC, please contact a member of our team below.
