The Office of the President is returning nearly €240,000 in unspent allowances during Michael D Higgins' first term.
The president's spending was a major discussion point during this year's election.
During the election campaign President Higgins refused to release details of how he spent his un-audited annual allowance of over €317,000.
Today Áras an Uachtaráin revealed there was an under-spend totalling €238,443 over the period of his first seven years.
He overspent in 2014 only, to the tune of €4,700.
The figures reveal that most of the allowance went on food and beverages - an average of around €132,000 a year.
Hospitality and Entertaining averaged around €85,000 a year.
The Aras says the overall under-spend will be returned to the Exchequer by the end of the year.
