Motor Tax Online is a secure service provided by the Department of Transport, which allows motor tax customers to tax their vehicles online with the PIN Number on their motor tax renewal notice RF100B which is sent by the Department of Transport.
Vehicles may normally be taxed online using the last 6 digits of your Vehicle Registration Certificate number as the PIN required by the online service. This number (beginning with the letter C) appears at the top right hand corner on the front of your Vehicle Registration Certificate.
In the case of the first taxing of a brand new or imported vehicle, the PIN is the last 6 characters of your vehicle’s chassis number as printed on your RF100 Form. You should have received your RF100 Form either from your motor dealer or the NCTS.
If you don’t have a home computer, you can still renew your motor tax on-line by using the Internet access available at your local library.
If you can’t retrieve your PIN or have other queries regarding online taxing, you should contact the Department of Transport at 0818 411 412
Pay by post or in person

2. RF100A / RF100A Irish– this is a blank motor tax renewal form
3. RF100B – this is a computer-generated renewal form issued by the Department of Transport which is posted to you when your tax is due to expire (and may include a PIN to allow you tax online).
You can use your preferred method of payment whether that is bank draft, cheque, Postal or Money Order, or by completing the Credit Card details section on the form.
