Dublin GAA generated more than €1.6m in commercial revenue in 2017, a hike of €130,000 that comfortably cancelled out a similar figure spent on the preparation of inter-county teams.
The commercial revenue figure contains the standard €175,000 distributed to all counties for their share of central commercial and media revenues.
Dublin's main sponsor is AIG but they have entered into partnerships with 12 other brands, allowing them to increase their overall take to €1,462,529.
A modest fundraising return of €54,997 was also recorded in accounts presented to the Dublin convention last night.
Team expenditure climbed by €90,000 to €1,604,353, second only to Cork who have spent over €1.74m.
Their share of the national league pot is €461,943, courtesy of their home league games and a league football final against Kerry.
Dublin's overall income was €4,481,063 with expenditure of €4,364,154.
Meanwhile, Limerick GAA had an operating deficit of €43,000 for the year as their team expenses rocketed by €250,000, despite the early exits of their footballers and hurlers.
The success of the U-21 hurlers, winning an All-Ireland title for the second time in three years, is incorporated into that figure.
The alarming figures were revealed at the weekend convention by outgoing treasurer Donal Morrissey who claimed he was excluded from the decision-making process with regard to financial matters.
Some €1,262,535 was spent on preparing all inter-county teams from U-17 to senior in hurling and football up from €997,418 in 2016. That included management costs of €270,000.
The sharp rise is in keeping with figures across the country that will see the overall expenditure on inter-county teams climb from €23,315,284 in 2016.
