Accumulated profits at the main entertainment firm owned by crooner Daniel O'Donnell last year topped the €3m mark.
DOD Promotions also recorded profits of €215,554 in 2013.
The O'Donnell entertainment business consistently produces strong profits on the back of a hectic touring schedule. The profits last year followed the firm recording a profit of €219,000 before exceptional items in 2012.
O'Donnell (52) announced earlier this year that he was taking an extended break from music from February 2015 after realising that "life is short".
O'Donnell said that he and his wife, Majella, had to take stock of things after her cancer diagnosis.
The new accounts filed by O'Donnell's firm show that the company's accumulated profits increased from €2.79m to €3m in the 12 months to the end of October 31, 2013.
Accounts for O'Donnell's DOD Promotions show that the firm's cash pile last year decreased from €1m to €875,452.
The firm's 2012 accounts show that it wrote down its fixed-asset investments from €2.6m to €500,000.
A major contributor to the wealth of DOD Promotions is the singer's own touring company, Brockwell.
The returns show that Mr O'Donnell's manager, Sean Reilly, and Majella O'Donnell serve as directors of DOD Promotions.
Latest accounts for Brockwell show that it had accumulated profits of €2m at the end of December 2012 and had cash of €989,373.
But O'Donnell previously said: "I've never sung to make money. When I'm performing I never think about how much I'm making on the night. I sing because I love it and the money is just a by-product of what I do.
"My biggest payment is being on the stage and that is a big part of the secret of my success. If it all ended tomorrow, I couldn't say there is anything the world could have offered me that is better than what I have.
"Being a 'personality' is, I suppose, what I have become as a result of my success as a singer.
"I do feel that I have handled it well because I haven't allowed it to change me as a person."
During his lucrative career, the entertainer has sold more than 10 million records and in June 2012, O'Donnell received the Freedom of Donegal in recognition of his contribution to music and the ambassadorial role he has undertaken for Donegal.
O'Donnell will add to his companies' coffers next week when he performs at Norsk Hostfest in North Dakota - while he will entertain passengers on a seven-day Caribbean cruise next February.
Away from touring and performing, O'Donnell carries out a lot of community-based work.
His wife Majella is to release her autobiography 'It's All In My Head' next month recounting her battle with cancer.
Donegal country music star Lisa McHugh is one of the new faces of Ireland's first international channel Irish TV. She will present series 'On the Road' travelling around the country and meeting some of Ireland's most popular singers, such as Daniel O'Donnell.
