Result: More than £100,000 removed from the initial exposure, £45,000+ penalty fully suspended, and a £9,000 monthly payment plan secured

A US-based e-commerce retailer approached Proactive Consultancy Group after HMRC opened an investigation into its historic UK VAT affairs.

The business sold goods to UK consumers through a major online marketplace. Some orders were dispatched directly from outside the UK, while other inventory was imported into the UK, stored at fulfilment centres and subsequently supplied to UK customers.

Although the business was VAT registered, it had misunderstood the VAT treatment of certain sales fulfilled from stock physically located in the UK.

By the time we became involved, the client’s potential historic exposure was approximately: £405,000.

For a relatively small overseas business, the financial consequences were potentially severe.

Key Case Facts

Sector: E-commerce / Online Retail

Client: US business selling to UK consumers

Initial exposure: Approximately £405,000

Formal VAT assessment: £301,895

Reduction from starting exposure: More than £100,000

Penalty: £45,295.95

Penalty suspended: 100%

Immediate penalty payable: £0

Debt including interest: Approximately £322,653

Payment arrangement: £9,000 per month

The Challenge

The client had been accounting for VAT correctly on its current transactions but historic sales fulfilled through UK warehouses had not been fully included in earlier VAT returns.

This created two immediate issues.

First, the business faced a substantial historic VAT liability.

Second, because the business had already changed its VAT treatment going forward, there was a significant risk of penalties arising from HMRC’s investigation into the earlier periods.

Our initial reconstruction identified approximately £337,500 of historic unpaid VAT before penalties. At that stage, penalties could potentially have been substantial.

The client’s ability to pay was also a serious concern. It made clear that a short repayment period could place the continued operation of the business at risk.

Reconstructing the UK Sales Position

Rather than simply accepting a broad historic liability, we reconstructed the underlying sales by VAT period.

A critical element was distinguishing sales that actually represented UK taxable transactions from the client’s wider international sales activity.

For example, our review of one early period identified total product sales of approximately £360,000, but only the portion fulfilled through the UK marketplace structure was identified as subject to UK VAT.

This period-by-period approach provided a substantially more reliable basis for determining the client’s actual UK VAT exposure.

Identifying Import VAT Credits

The output VAT calculation represented only one side of the equation.

Inventory stored in UK fulfilment centres first had to be imported into the UK. This meant that import VAT had potentially already been paid when the goods entered the country.

We therefore examined the client’s historic import position and specifically investigated VAT charged through its freight and customs arrangements.

The client confirmed that VAT had been charged by its freight provider when goods entered the UK, and we analysed the extent to which that import VAT had already been recovered or could be taken into account in establishing the correct liability.

This prevented the historic calculation from focusing solely on additional output VAT without giving appropriate consideration to the client’s import VAT position.

Challenging the Starting Exposure

The parties used £405,066 as the starting exposure for measuring any reduction ultimately achieved.

That figure reflected the estimated VAT payable together with an assumed minimum penalty component. The client was sufficiently concerned about the exposure that specialist support was structured on a success-related basis, with fees linked directly to reductions below that starting point.

Following the reconstruction of the sales and import VAT position and discussions with HMRC, the formal VAT assessment was ultimately reduced to: £301,895.

This removed more than £100,000 from the initial £405,000 exposure before considering the separate penalty outcome.

Turning the Penalty Position Around

The potential penalty position was another significant risk.

At the outset, there was concern that HMRC could treat the historic inaccuracies severely because the business had subsequently begun applying the correct VAT treatment without voluntarily correcting all earlier periods.

Our strategy was therefore based on full cooperation with HMRC, transparent disclosure of the historic position and demonstrating that the errors arose from misunderstanding rather than intentional non-compliance. The correspondence shows that from the outset we were seeking to move the behaviour away from a potentially deliberate characterisation and obtain the most favourable penalty treatment available.

HMRC ultimately treated the inaccuracies as careless rather than deliberate.

The calculated penalty was: £45,295.95

HMRC agreed to suspend: £45,295.95

Immediate penalty payable: £0

This was a major part of the overall result. The client avoided an additional immediate cash cost of more than £45,000.

Solving the Cash-Flow Problem

Even after significantly improving the client’s tax and penalty position, the remaining liability was substantial.

An immediate lump-sum payment could have put the overseas business under severe financial pressure.

We therefore entered into separate negotiations with HMRC’s Debt Management team.

The eventual HMRC arrangement covered an outstanding balance of approximately £322,653 including interest and allowed the business to repay the debt at:

£9,000 per month

This gave the client a realistic route to bringing its historic UK VAT affairs completely up to date without an immediate payment that could have threatened the viability of the business.

The Result

Our involvement produced several distinct benefits for the client:

  • The starting exposure of approximately £405,000 was challenged and the formal VAT assessment was reduced to £301,895.
  • The client’s historic sales and import VAT position was reconstructed rather than relying on a broad assessment.
  • A potential penalty of £45,295.95 was fully suspended, leaving £0 immediately payable in penalties.
  • HMRC accepted the behaviour as careless rather than deliberate.
  • A sustainable repayment arrangement of £9,000 per month was secured.

Why the Case Matters

For overseas e-commerce businesses, the VAT consequences of selling into the UK depend heavily on how goods reach the customer.

Goods dispatched directly from overseas and goods imported into and stored within a UK fulfilment centre can produce very different VAT consequences.

The case also demonstrates why an HMRC investigation should be considered as a whole.

The ultimate commercial outcome may depend not only on the amount of output VAT identified, but also on:

historic transaction analysis, import VAT recovery, assessment periods, behavioural classification, penalties, interest and the client’s ability to pay.

For Proactive Consultancy Group, the case demonstrates our approach to complex HMRC investigations: reconstruct the actual liability, identify every legitimate credit, challenge excessive exposure, minimise penalty risk and negotiate a practical route to settlement.
