As a public service broadcaster, RTÉ publishes the earnings of its highest paid presenter’s every year.
In 2021, RTÉ said Mr Tubridy earned €440,000 (£376,250), about €26,000 (£22,200) less than what he made the previous year due to a 15% pay cut.
However, it recently said that it had misstated figures for Mr Tubridy’s pay, and the presenter had actually earned €515,000 (£440,380) in 2021.
The extra payments were found during an audit of the broadcaster’s finances.
It said that between 2017 and 2022 Mr Tubridy received a series of payments totalling €345,000 (£294,300) above what was made public.
A review, the organisation’s board said, found that under a separate agreement Mr Tubridy was guaranteed €75,000 (£64,000) of additional annual income by RTÉ which was intended to be paid by a commercial partner.
However, the partner did not renew the contract for a second year, and given it was guaranteed by RTÉ, the payments were made directly by the broadcaster to Mr Tubridy’s agent.
As a result, he received two payments totalling €150,000 (£128,000) in 2022, for that year and the previous year.
