A Cork-based radio DJ has been named on the Revenue tax defaulters list for under-declaration of income tax.
The morning host on Red FM, Neil Prendeville, has claimed his firm of accountants did not make the correct tax returns.
He said he was advised by them that all his taxes had been properly paid, and he was fully tax compliant.
Mr Prendeville issued High Court proceedings against this firm.
He said this case was quickly settled and he was also awarded compensation.
"Although Mr Prendeville had acted at all times on the advice of his accountants, the Revenue have a statutory obligation, and no discretion but to publish Mr Prendeville's name as a tax defaulter", a statement on his behalf said.
A new accountancy firm were employed to rectify the situation.
The filings by Revenue show Mr Prendeville owed some €541,636 between tax, interest and penalties.
However the insurance company for the accountancy firm paid all the penalties, interest and legal costs.
While the private ambulance service Lifeline has also been ordered to pay €416,965 for under-declaration of PAYE/PRSI or USC.
Lifeline Ambulance Service was formed in 1999 to provide transport for hospital inpatients.
Its service has expanded to cover repatriations, event cover, standby's and organ transport services.
The company says it is the biggest private ambulance provider in Ireland, and the number one provider to the Helath Service Executive (HSE).
The owner of Lifeline, David Hall, said: "This followed a voluntary disclosure made by me to Revenue in 2015 on historic underpayment of taxes due on staff expenses between 2008 - 2015.
"The settlement consists of €287,031 in underpayments, €70,884 in interest and a €59,050 penalty.
"During this time Lifeline employed 108 staff and had a turnover of €5-7m per year and this underpayment relates to approximately €35,000 per year which is 0.75% of turnover approximately."
Mr Hall stepped away from Lifeline in 2010 to focus on solutions to mortgage arrears.
In August 2015, he returned to the firm "to protect the staff and business", after he was told it was in trouble.
"During a full review of the business I noticed non-adherence by the company to correct Revenue mileage policy when it came to some employees.
"In October 2015, in the wake of a voluntary disclosure by me, a Revenue audit followed."
He added: "Lifeline is profitable again following a complete restructure. The audit was revisited in June 2019.
"No additional under payments were found and no additional fines or penalties were issued.
"The figures given to revenue by me were the figures accepted by Revenue".
Separately on the list, a Wexford-based engineer was fined €169,454 for non-declaration of capital gains tax in the amount of €127,243.
While a retired housekeeper in Donegal has been ordered to pay €89,839 for non-declaration of capital gains tax and income tax.
The total amount of fines and penalties imposed were €799,613.
