Brexit: Will it affect us? Will it affect tax? There is huge uncertainty as to exactly how and when the UK will impliment Britain's Exit from the European Union (Brexit), and even less certainty as what will come in its place.

The UK might:

The table below provides an indication of what the first and third of these could mean for direct and indirect taxes. 

The tax issues arising from a bilateral treaty depend entirely on the terms negotiated. Based on the Canada and Switzerland agreements it is likely that some EU rules would need to be adopted such that the position would be similar as for EEA membership.

In the absence of a crystal ball, this all remains speculative.  As HMRC’s phoneline message says it is therefore very much a case of ‘business as usual’ at present.

  Current position EEA Membership Out of EU completely
Direct Tax EU law takes precedence over UK law EEA law must be considered when interpreting UK law UK not subject to EU or EEA law
Recourse to EU Courts (ECJ / CJEU) Recourse to EFTA Court No recourse to EFTA / EU Courts
EU freedoms have influence on direct tax rules, including restrictions on state aid Similar rules apply

No requirement to comply with EU freedoms

May be scope to widen SME tax incentives as state aid rules would not need to be considered

Interest and Royalties directive eliminates withholding tax on cross border payments.

Directive would not apply

Withholding tax levels would depend on individual treaties (which may not get you to 0%)

Capital Duties Directive prevents member states from charging indirect tax on companies raising capital.

Directive would not apply

Social Security Agreement means workers moving in the EU are only subject to social security in one country Same agreement applies UK may wish to sign up to agreement as other non-member states (e.g. Switzerland) have.
Indirect Tax Indirect taxes are harmonised and the UK is obliged to respect EU VAT legislation.

UK would not be subject to EU VAT legislation.

Given the revenues involved the UK would be likely to retain its VAT system in some form.

There may be additional burdens for business operating in the EU.

Customs Duties Customs duty is an EU tax imposed by EU regulations.

Customs duties would no longer apply:

  • Revenues would be lost.
  • Duties would be charged on the export of goods from the UK to the EU.

However, the UK would most likely enter into some form of agreement with the EU / EEA so there may be little change other than to compliance procedures.
