Since Brexit, VAT and customs rules for trade between the Republic of Ireland and the UK have undergone significant changes. Businesses now face new requirements when moving goods and services across borders, and understanding these VAT implications is essential for compliance and cashflow management.
Trading between Ireland and Great Britain is now treated as international trade, with customs and VAT barriers post-Brexit affecting both imports and exports. Companies must be aware of:
For Northern Ireland, trade with Ireland and the EU remains covered by the Northern Ireland VAT Protocol under the Windsor Framework VAT rules, requiring an XI VAT number for certain transactions.


When goods move between Ireland and Great Britain, the following rules apply:
For Northern Ireland, Intrastat rules Northern Ireland–EU still apply for statistical reporting of goods movements.
The rules for VAT on services Ireland to UK B2B differ from VAT on services Ireland to UK B2C:
This includes VAT rules for digital services Ireland–UK, where place-of-supply rules determine which VAT rate applies.


Some sectors face additional complexity:
To trade smoothly, businesses should:


Brexit has significantly altered the VAT implications for trade between the Republic of Ireland and the UK, particularly for B2C sales of goods. Before 1 January 2021, Irish companies selling to UK consumers could apply Irish VAT until the distance sales threshold was met. However, post-Brexit rules have changed this approach entirely.
Previously, Irish businesses selling goods directly to UK customers charged Irish VAT until they exceeded the UK’s distance sales threshold of £70,000. Once that threshold was reached, the business was required to register for UK VAT.


From 1 January 2021, the distance sales threshold for VAT registration no longer applies for goods shipped from Ireland to Great Britain. Instead:
The Northern Ireland VAT Protocol means sales from Ireland to Northern Ireland are still treated as intra-EU transactions. This allows businesses to continue applying EU VAT rules, supported by the XI VAT number Northern Ireland system under the Windsor Framework VAT rules.


Irish businesses selling goods directly to UK consumers now face new compliance steps:
For B2C sales of goods from UK businesses to customers in the Republic of Ireland, the VAT implications for trade between Ireland and the UK remain an important compliance consideration post-Brexit.
UK companies selling goods to Irish consumers must register for Irish VAT and charge it on their supplies, regardless of whether they meet a sales threshold. This is because the previous distance sales threshold no longer applies for trade from the UK to the EU.




Goods shipped from Northern Ireland to Ireland are treated differently under the Northern Ireland VAT Protocol and Windsor Framework VAT rules. These movements are still considered intra-EU supplies, so EU VAT rules apply, and businesses may need an XI VAT number Northern Ireland instead of registering for Irish VAT separately.
Following Brexit, the UK is now treated as a non-EU country for VAT purposes. This means that many B2C services supplied from Ireland to UK customers are no longer subject to Irish VAT — but only if certain conditions are met under the use and enjoyment provisions.


Irish VAT is generally not applicable on the following VAT on services Ireland to UK B2C categories when supplied to non-business customers based outside the EU, including the UK:
If a service is not included in the above list and is supplied to a non-business customer outside the EU (including UK consumers), then Irish VAT must be charged at the applicable rate. This applies to certain leisure, entertainment, and in-person services, which may also fall under VAT in entertainment cross-border Ireland–UK rules.

Post-Brexit, the movement of goods from the EU to Ireland through the UK is subject to new customs and VAT rules under both the Union Customs Code and the EU–UK Trade and Cooperation Agreement (TCA). Irish Revenue has clarified several scenarios for goods transiting the UK before entering Ireland, each with its own VAT and customs implications.
When goods originating in the EU are shipped to Ireland but physically pass through the UK (e.g., via a UK port or logistics hub), special provisions apply:


If EU goods enter UK free circulation (i.e., cleared for sale in the UK) before being shipped to Ireland, they lose their EU origin status:
Where goods move through Northern Ireland en route to Ireland, the Northern Ireland VAT Protocol and Windsor Framework VAT rules may allow them to be treated as intra-EU movements rather than imports.
