What documents do I need to tax a car at a Post Office in Northern Ireland?

GOV.UK specifically lists a paper insurance certificate or cover note and an original MOT certificate or suitable TEC evidence for Northern Ireland Post Office transactions.

You will also need the appropriate V5C, new-keeper slip or tax application document depending on the transaction.

Online taxation can be simpler because some checks are electronic, but if you use the Post Office, take the originals requested rather than assuming a phone screenshot will be accepted for every document.

For 'What documents do I need to tax a car at a Post Office in Northern Ireland?', keep the DVLA confirmation or reference number once the transaction is completed. Tax, SORN and keeper records are separate, so a dated confirmation helps show exactly when your responsibility changed.
