The latest tax defaulters list includes five medical consultants who made settlements as part of Revenue’s ongoing inquiry into the profession.

Twelve medical consultants have previously made settlements as a result of Revenue’s investigation, and more are expected to feature in future lists.

So far, the investigation into more than 500 medical consultants has netted more than €30 million in unpaid tax and penalties.

Officials found many had set up “controlled companies” to maximise their incomes but which were found to be involved in aggressive tax planning and avoidance.

The bulk of cases investigated to date are focused in Dublin but the inquiry has since been expanded nationwide.

In the biggest settlement in the current list, Humphrey Onome Ugbawa, a medical doctor and company director with an address at 1 The Green, Ocean Links, Strandhill, Co Sligo paid €1.54 million to Revenue.

Cardiothoracic surgeon Michael Tolan, of Suite 38, Hermitage Medical Clinic in Lucan, settled for €411,180, while three other doctors made settlements ranging from €109,000-125,000.
