Six people have made settlements of more than 1 million euro with the Revenue for tax issues.
Among the names on the latest defaulters' list was retired company director John Joseph McCarthy, formerly based at Flower Lodge, Strawhall, Fermoy, Co Cork.
He racked up the largest bill and paid 6.25m euro to the tax inspectors for underdeclaration of income tax, capital gains tax and stamp duty.
The business owed 1.8m euro in tax and was also fined 1.4m euro.
Gerald Clarke, a farming contractor from Greaghaduff, Bailieboro, Co Cavan racked up a bill of 1.43m euro for underdeclaration of VAT and income tax.
Pharmacist James Connolly from the Square in Kildare town settled for 1.25m euro for underdeclaration of income tax and capital acquisitions tax.
Landlord Patrick Wheelock, from Moneyhore, Enniscorthy, Co Wexford made a settlement for 1.1m euro for underdeclaration of income tax and VAT.
The Revenue said that in the three months to the end of September settlements relating to 88 taxpayers worth 27.6m euro were published.
Eight settlements exceeded 500,000 euro.
The list carried the usual mix of professions including meat wholesalers, publicans, dentists, horse breeders, farming contractors and a stockmarket advisor.
Revenue said it was a portion only of all audits and investigations concluded in the period and the names on the list are only released when chances to make voluntary disclosures are not availed of and the default is classed as careless or deliberate behaviour.
Some 1,888 Revenue audits and investigations and 21,449 risk management interventions were settled from July to September bringing in 116m euro for the Exchequer.
Elsewhere on the defaulters' list, 50 people were prosecuted for using laundered fuel.
Sentences for the offence ranged from fines of 2,500-10,000 euro, right up to one company director who was jailed for two years.
Ten people were named for cigarette smuggling. And another five for illegal selling of tobacco.
Three of the people found to have been smuggling live outside of Ireland - two in Estonia and one in Romania - and only three of them were sentenced to anywhere from three months to a year behind bars. One man had received a suspended sentence.
The fines for the cigarette smugglers ranged from 2,500-3,000 euro.
