Specialist VAT Advice: VAT Compliance Through Expert Consultancy

VAT compliance is an essential aspect of business operations, but it’s not always straightforward. While standard VAT guidance covers most scenarios, often particular VAT transactions don’t fit neatly into the usual rules, leaving businesses uncertain about the correct VAT treatment and potentially facing HMRC enquiries.

Complex VAT supplies, international VAT requirements, and industry-specific VAT regulations can all create significant challenges. Getting these wrong can lead to unexpected tax liabilities and potential interest and penalties. Having expert VAT advice available ensures businesses receive clear, reliable answers to their bespoke scenario when they need them – without the excessive delays that have become commonplace when dealing directly with HMRC.


Recent statistics highlight the difficulties businesses face when seeking clarification on VAT matters directly from HMRC:

  • In the year to March 2023, taxpayers and their agents spent an astonishing 798 years (7 million hours) waiting to speak to an HMRC adviser
  • This represents more than double the 365 years (3.2 million hours) spent waiting in 2020
  • Correspondence handling has fallen significantly short of targets, with fewer than half (45.5%) of responses provided within 15 working days in 2022 – well below the 80% target
  • HMRC has acknowledged it won’t meet its telephone performance target for 2024-25, creating ongoing uncertainty for businesses seeking VAT guidance

These delays make obtaining timely VAT advice through official channels increasingly challenging, heightening the value of expert VAT consultancy services that can provide rapid, reliable guidance.


Many businesses manage their VAT returns and affairs effectively, but certain situations require deeper VAT expertise. Common VAT scenarios that demand specialist support include:

The VAT treatment for property transactions varies depending on whether a building is residential or commercial, new or existing, or subject to an option to tax. Errors in accounting for VAT on property transactions can result in significant unexpected tax costs that impact project viability and profitability.

Organisations that make both VAT-exempt and taxable supplies – such as financial service providers, charities, and healthcare organisations – need to calculate their recoverable input VAT carefully using approved partial exemption methods. Understanding these VAT recovery calculations ensures businesses neither overclaim VAT (risking penalties) nor underclaim VAT (increasing costs). Considering the most efficient method available may provide additional VAT recovery opportunities.

Businesses trading in goods or services across borders may need to navigate VAT registration requirements in other countries, import VAT rules, and special VAT schemes like the One Stop Shop (OSS) and Import One Stop Shop (IOSS) for services. Brexit has introduced additional layers of VAT complexity for UK businesses selling to EU customers, requiring specialised knowledge of both UK VAT and EU VAT regulations.

Certain industries, including education, hospitality and not-for-profit organisations, have specific VAT exemptions or special VAT rules. Applying the correct VAT treatment is vital for maintaining compliance and maximising VAT efficiency within your sector.


VAT is a transaction-based tax, meaning businesses must apply the correct VAT treatment at the point of the supply. VAT mistakes can lead to:

  • Unplanned VAT liabilities that impact cash flow and business planning
  • HMRC penalties and interest charges when VAT corrections are needed
  • Missed opportunities to optimise VAT recovery, increasing overall business costs
  • Time-consuming VAT investigations and correspondence with HMRC

Rather than spending valuable time interpreting complex VAT legislation or waiting in HMRC queues for clarification, working with a VAT specialist provides businesses with practical, tailored VAT advice specific to their situation—typically within days rather than months.


For businesses with regular VAT questions, a VAT consultancy service on a retained basis offers:

  • Direct access to VAT expertise without the administrative delays experienced with HMRC
  • VAT advice tailored to specific transactions rather than general guidance
  • Clear written VAT opinions for record-keeping, compliance documentation, and future reference
  • Predictable costs through a fixed-fee VAT advisory structure
  • Rapid response times, with queries handled or updated within 48 working hours—dramatically faster than HMRC’s current performance where fewer than half of queries receive responses within 15 working days

Having professional VAT support gives businesses confidence that VAT compliance matters are handled correctly from the outset. This allows finance teams to focus on strategic business priorities without worrying about VAT risks or spending excessive time on HMRC hold lines.


While VAT follows clear principles in many situations, complex business circumstances often require specialised VAT knowledge to ensure correct application and optimal VAT efficiency. Whether dealing with cross-border VAT requirements, partial exemption calculations, or property-related VAT matters, having access to expert VAT guidance prevents costly errors and saves valuable time that would otherwise be spent navigating HMRC’s increasingly stretched resources.

For organisations that need ongoing VAT support, a retained VAT consultancy relationship provides a cost-effective way to access expertise when it matters most, with response times measured in hours rather than weeks or months.
