Tax Clearance Certificate

A Tax Clearance Certificate is a written confirmation from Revenue that a person's tax affairs are in order at the date of issue of the Certificate.

In some instances a Certificate may be issued to a customer who has tax arrears provided such arrears are covered by an instalment arrangement that has been agreed with Revenue.

The requirement to produce a Tax Clearance Certificate usually arises in the context of a person seeking State money (e.g. Government contracts, grants) or obtaining licences (e.g. excise licence, road transport licence). An individual or business that has been approved for DLR CEB funding must hold an up-to-date certificate in order to draw down funds.

To apply for a certificate, visit and download a form for submission to your local tax office. You can also apply online. If in doubt, call Revenue on (01) 632 9400 (Dún Laoghaire-Rathdown residents).
