Specialist Tax Advice Since 2007

Proactive Consultancy Group is a specialist tax advisory firm focused on complex VAT matters, HMRC disputes, historic tax reviews and high-value recovery opportunities.

Since 2007, we have helped businesses recover more than £120 million from HMRC, in addition to delivering multi-million-pound savings through successful technical challenges, reductions in proposed liabilities, penalty mitigation and negotiated settlements.

Our track record includes numerous individual engagements resulting in recoveries or savings exceeding £500,000, reflecting both the scale of the matters we handle and the depth of our specialist experience.

We are often engaged where the tax position is complex, the financial exposure is significant, or an existing interpretation needs to be reconsidered.

Our clients range from entrepreneurial and privately owned businesses to major UK and international organisations operating across healthcare, diagnostics, technology, e-commerce and other complex sectors.

Proactive Consultancy Group forms part of a wider international tax advisory group with established operations in Canada, the United Kingdom and Ireland.

The Group’s Canadian business, Canadian SR&ED, is a leading specialist tax consultancy focused on Scientific Research and Experimental Development tax incentives and other innovation funding programmes. In Ireland, the Group operates through NX Advisory, providing specialist support to businesses in relation to Irish R&D tax incentives and related advisory matters.

The Group is headquartered in Calgary, Alberta, with satellite offices in Vancouver, Toronto, London and Dublin, giving our clients access to specialist expertise across multiple jurisdictions.

A Track Record Built Over Nearly Two Decades

These results have been accumulated over many years and across a substantial portfolio of client engagements. They are not simply the product of identifying repayment opportunities. Our work has also involved preventing incorrect liabilities from arising, substantially reducing HMRC assessments, defending historic tax positions and resolving disputes where significant amounts were at stake.

What We Do

We specialise in tax matters that require detailed technical analysis rather than routine compliance.

Many of our engagements involve several of these areas simultaneously.

A change in the VAT treatment of one revenue stream, for example, can affect output VAT, input VAT recovery, partial exemption calculations, historic returns and potentially penalties and interest.

Our role is to understand and resolve the complete position.

Our work includes:

  • VAT recovery and historic error correction
  • healthcare and medical VAT exemption
  • partial exemption
  • HMRC enquiries and compliance checks
  • VAT assessments and technical disputes
  • complex supply and liability analysis
  • principal and agent arrangements
  • cross-border and international VAT
  • import VAT
  • historic VAT reconstruction
  • penalty mitigation
  • settlement and Time to Pay negotiations
