However, you can still tax your vehicles online at www.motortax.ie or call into any of the other Motor Tax Offices in Letterkenny, Lifford, Milford, Dungloe or Donegal Town.
Every effort is being made to resolve this issue and we hope to have this service available as soon as possible.
For any other queries contact the Council on 074 91 53900 or visit www.donegalcoco.ie
UPDATED: The motor tax service at Carndonagh is now re-open.
