Revenue investigations and settlements between the start of April this year and the end of June resulted in €135m in income.
The Revenue Commissioners' list of defaulters who made settlements with them in the three months from April to June this year includes the largest tax settlement ever made public by Revenue.
Leslie Reynolds and Company Ltd, of 126 East Wall Rd, Dublin, is engaged in the sale and distribution of engineering components.
The company paid €9.5m to the Revenue. On top of this Leslie Reynolds himself, with an address at Offington Lawn, Sutton, Co Dublin, made a personal tax settlement of €400,000.
The case involving Mr Reynolds and his company came about as a result of a Revenue tax audit that highlighted underpayment of corporation tax, VAT, income tax and PRSI.
Mr Reynolds pleaded guilty to tax evasion in the Circuit Criminal court in July. His case is currently adjourned awaiting sentencing.
The tax defaulters' list shows that a total of €6.3m of the €9.9m Mr Reynolds and his company had to pay was interest and penalties on the original tax due.
The second highest settlement included in today's list relates to cattle dealer and farmer Patrick Brady of Lakefield, Gort, Co Galway. He settled for €3.39m as a result of a Revenue investigation into undisclosed funds he had invested in a bogus non-resident account.
A settlement for €3.32m was made on behalf of deceased company director James Murray, of Hadley, Coast Road, Mornington, Co Meath. Mr Murray had been an investor in the Ansbacher offshore accounts that were operated by former Taoiseach Charles Haughey's financier Des Traynor.
Another Ansbacher investor, retired company director Thomas Clifford, of The Kerries, Tralee, Co Kerry, paid €3.1m.
Overall, today's Revenue list includes 170 settlements, eight of which were over €1 million each. The total amount raised from these 170 tax defaulters was €39.5m.
97 of the cases listed involved people who had money invested in bogus non-resident accounts, while 21 related to the investigation into Offshore Accounts and Assets.
Two involved Ansbacher Investors, and one, for €200,000, concerned a person who invested in National Irish Bank's controversial CMI offshore investment scheme.
The names published today are those of taxpayers with settlements in excess of at least €12,700. Other settlements too small for publication raised an additional €95m for the Exchequer.
