VAT on International Trade Post-Brexit: Real Challenges for UK SMEs in 2025

Since Brexit, the UK's departure from the EU has reshaped how small and medium-sized enterprises (SMEs) manage VAT on international trade. Navigating import and export VAT, customs declarations, and cross-border services compliance presents new complexities—and opportunities. This blog post outlines the practical challenges SMEs face, with insights for tax consultants helping clients thrive amid regulatory changes in 2025.

1. Overview of Post-Brexit VAT Changes

Brexit ended the UK’s participation in the EU VAT regime, introducing:

  • Separate VAT regimes for the UK and EU.
  • Customs declarations for goods crossing borders.
  • New VAT registration and reporting requirements for cross-border sales.
  • Changes in place of supply rules for services.

These changes impact every SME engaged in international trade, requiring new compliance measures and strategic planning.

2. Import VAT: Key Considerations for UK SMEs

Customs Declarations and Import VAT

All goods entering the UK from the EU or other countries now require customs declarations. VAT is charged at importation based on the customs value, which includes:

  • Purchase price of the goods.
  • Shipping, insurance, and related costs.
  • Duties and other taxes.

Accounting for Import VAT

SMEs can use the Postponed VAT Accounting (PVA) scheme to declare and reclaim import VAT on the same VAT return, improving cash flow by avoiding upfront VAT payments at the border.

  • Benefits:
    • No immediate cash outlay on VAT when goods enter the UK.
    • Simplifies VAT accounting.
  • Requirements:
    • VAT registration in the UK.
    • Accurate record keeping and declaration on VAT returns.

Common PVA Pitfalls to Avoid

ExplanationHow to Avoid
Incomplete customs dataMissing items can delay clearance or trigger finesUse reliable customs brokers and software
Improper use of PVADeclaring VAT twice or missing declarationsTrain staff and reconcile import records
Not updating VAT registrationsChanges in business activity can affect eligibilityReview VAT status regularly

3. Export VAT: Becoming Zero-Rated

Exports from the UK to non-UK countries—including EU member states—are zero-rated, meaning no VAT is charged on exported goods, provided proper evidence is retained.

Export Documentation Requirements

  • Proof of export (shipping documents, commercial invoices).
  • Contracts and order confirmations.
  • Customs paperwork for EU and non-EU countries.

Maintaining comprehensive records is essential to claim zero-rating and withstand HMRC audits.

4. Cross-Border Services: Complex Place of Supply Rules

Post-Brexit, VAT on services depends on the place of supply:

  • B2B services: Generally taxed where the customer belongs. UK businesses selling to VAT-registered EU businesses will not charge UK VAT.
  • B2C services: VAT is usually charged where the supplier belongs, but certain exceptions apply, especially for digital services.

Understanding OSS for Non-Union Businesses

UK businesses selling digital services to EU consumers must consider the Non-Union One Stop Shop (OSS) scheme to simplify VAT registration and reporting across multiple EU countries.
