The estate of the late Des Traynor has made a settlement of €4m with the Revenue Commissioners.
Mr Traynor was a central figure in the Ansbacher tax evasion scandal.
His name is included in the quarterly list of tax defaulters published today.
Mr Traynor administered funds which paid for former Taoiseach Charlie Haughey's lifestyle.
Mr Traynor was chairman of cement company CRH, and he also designed a complex system of tax evasion for Ireland's business elite.
Funds were held off-shore at the Ansbacher bank in the Cayman Islands.
His estate reached a settlement because he held an Ansbacher account and under-declared other taxes.
Jack Stakelum, a former associate of Mr Traynor, was also included in today’s list of tax defaulters.
The retired accountant, who lives in Kilpedder, Co Wicklow, made a settlement of €425,000.
He ran the Ansbacher accounts, met Mr Haughey regularly and ensured the former Taoiseach's household expenses were paid.
Earlier this year Mr Stakelum was disqualified from involvement in the management, that is, from being a Director, of any company for five years.
The High Court found he acted in a calculated way to facilitate tax evasion.
He made a settlement for holding an Ansbacher account and under-declaring income tax.
