Minister for Public Expenditure and Reform Paschal Donohoe has identified an issue that he is going to address in relation to his expenses during General Election 2020 in the coming days, according to sources.
It is understood the issue is seen as not as significant as his recently amended declaration to the Standards in Public Office Commission in relation to a donation by businessman Michael Stone for General Election 2016.
It is also believed the minister may speak publicly on the issue before the Dáil resumes on Tuesday.
A spokesperson for the minister has declined to comment.
Sinn Féin finance spokesman Pearse Doherty had said it is now time for Minister Donohoe to "come clean about everything".
He said if the minister is going to disclose further information in relation to General Election 2020 that information "must be disclosed immediately".
Earlier, Green Party leader Eamon Ryan has said questions surrounding Minister Donohoe are not distracting from the work of Government.
In a statement to the Dáil on Wednesday, Minister Donohoe said that during a review "in recent weeks" he was made aware for the first time that "a personal payment" of €1,100 had been made to workers who put up election posters in 2016.
He acknowledged that he made a "clear mistake" in not including the cost in his election expenses, something for which he apologised.
The expenses were amended on Sunday and given to the Standards in Public Office Commission (SIPO), he said.
Speaking in Athlone today, the Minister for the Environment said the Dáil arrangements are set and Mr Donohoe will answer questions on Tuesday, which is "appropriate".
"The Dáil arrangements are set. We don't have the Dáil over the weekend and the opposition were looking for it to be done it the Dáil, so I think Tuesday is the first time," he said.
Earlier today, Labour's Spokesperson on Finance and Public Spending Ged Nash has said there are "serious questions" to be asked of Mr Donohoe on issues surrounding his declaration in respect of the 2016 General Election campaign.
Speaking on RTÉ's Morning Ireland, Mr Nash said the minister has had several opportunities over the past number of years to address the issue and "he failed to do that".
"We have the rather puzzling situation where the minister has requested again the opportunity to make a statement in the Dáil next week, this time with Q&A."
Mr Nash added: "We have questions. Serious, serious questions."
He said when this issue first came to light in 2017, Minister Donohoe should have had questions for his election agent "who's responsible, legally, for election returns - who carried out the labour and at what cost?"

"And it seems to me that no examination of that particular issue occurred at that point in time.
"The minister now is trying to make the case, and I think he's failing to do so convincingly at least, that this is a donation that was made to the Fine Gael Dublin Central constituency organisation, but in fact, in the context of an election, there really is no such thing and the only person who can incur expenditure on behalf of, or authorise expenditure, is the election agent on behalf of the candidate.
"There's an attempt here to re-engineer the facts to present them in a certain way to bring a donation, a corporate donation to an individual candidate and different levels and standards in terms of thresholds apply, so an attempt here, I think to present the facts in in a particular way."
6 key points in the Paschal Donohoe expenses controversy
A measured approach should be taken, according to Fianna Fáil TD Barry Cowen.
Speaking on RTÉ's Today with Claire Byrne, he said Minister Donohoe's actions do not constitute "a sackable offence".
"No way should he be hounded out of office," Mr Cowen said.
"Is this a sackable office? Is it an offence that warrants or merits resignation? No, I don't believe it is when you measure his wrongdoings, his failures, his mistakes and his apology which is the other side of the scale which I mentioned.
"All of the positive aspects of his character should not necessarily exonerate him from wrongdoing but it should be noted and measured in considering his potential and his benefit to this State, and you measure that against any wrongdoing and quantify that wrongdoing."
Mr Cowen spoke about his own sacking in 2020.
"Of course people will say, Micheál Martin sacked me because I refused to answer questions in the Dáil as I favoured due process in the form of an independent investigation by GSOC.
"This week Paschal Donohoe said in the Dáil he wouldn't answer questions, favouring due process in the form of an independent investigation by SIPO.
"So if you look at that in face value you immediately try and say a precedent has been set, therefore he has to suffer the same consequences. But I don't subscribe to that, irrespective of the rights or wrongs of my case."
