The expenses are worth over €2000
Sinn Féin has uncovered 5 separate expenses it should have declared for the 2016 General Election campaign.
The party will now have to resubmit its returns to the Standards in Public Office Commission.
The expenses, worth over €2000, relate to six press conferences held in Dublin venues in 2016.
The party said it regrets the omissions.
The news comes following recent revelations that Minister for Public Expenditure Pascal Donohoe failed to declare expenses in the 2016 and 2020 election.
