How do I register a car brought from the Republic of Ireland to Northern Ireland?

Because the Republic is in the EU, NI has specific treatment for EU vehicle arrivals. Used vehicles are not automatically charged VAT in the same way as “new means of transport”; HMRC’s definition of new includes vehicles under the age/use thresholds it publishes.

You will need the Irish registration document and purchase evidence. A vehicle not yet registered in the UK can be added to the DVA test-booking system using the foreign/RoI vehicle webform where an NI test is needed.

Do not drive around indefinitely on Irish plates after becoming resident and permanently importing the vehicle. Temporary-import rules and permanent-registration rules are different.

Republic of Ireland to Northern Ireland movements sit inside the special NI/EU customs framework. NOVA notification is important, but the VAT outcome depends on facts such as whether the car is a “new means of transport”, the seller’s VAT status and the vehicle’s age/use. Customs duty treatment is also different from a vehicle arriving in NI from outside the UK and EU. Applied to the actual NI case, a car brought permanently from the Republic of Ireland to Northern Ireland normally needs HMRC/NOVA notification, any VAT due dealt with, appropriate approval evidence, then DVLA registration and NI testing arrangements. The safest NI approach is to verify the current DVA, DfI, PSNI, DVLA or HMRC record that governs the point before acting.
