Minister of State Robert Troy has apologised for what he called serious "mistakes" in relation to "omissions" he made regarding property he owned that should have been included in a register of politicians' interests.
The junior minister confirmed he has now submitted seven amendments to the Register of Members to correct inaccuracies.
In a statement today, he said he had been under the "mistaken impression" that only property in his possession on 31 December of any year needed to be registered and not properties sold during that year.
He said: "I take my role and responsibility as a TD for Longford-Westmeath and Minister of State very seriously and I fully appreciate the seriousness of my mistake.
"I sincerely regret that my omissions and errors could be seen as my deflection or disregard of my responsibilities as public representative.
"I take full responsibility and I apologise unreservedly to my constituents, colleagues in Government, to the Dáil, and to SIPO for these errors and omissions."
The development comes after website On The Ditch ran a series of reports on the issue.
Minister Troy denied that he had insisted that rent be paid to him in cash.
He said that Westmeath County Council paid rent to him through electronic transfer.
He also rejected allegations of improper tax conduct and said he was fully tax compliant as a landlord and as a public representative.
This afternoon, Taoiseach Micheál Martin said he "accepts and acknowledges Minister Troy's apology, and welcomes his comprehensive statement to clarify the issues, and his amendments to the Register of Members' Interests".
However, People Before Profit TD Paul Murphy said he had made an additional complaint to the Standards in Public Office Commission regarding Mr Troy.
Mr Murphy has already requested that SIPO hold an investigation into Mr Troy's disclosures.
Mr Murphy said: "We now have at least seven breaches of the ethics legislation by Minister Troy. That includes four failures to declare property, one failure to declare a directorship and two failures to declare contracts with a council."
Earlier this week, a spokesperson for SIPO confirmed said any property valued over €13,000 had to be disclosed if it was owned by a public representative.
However, the sale of a property to a local authority does not need to be declared.
In terms of amendments made to the Register of Public Interests Robert Troy detailed the following changes.
2021 - I have now added that I have my former registered private dwelling house (PDH), Main Street Ballynacargy, rented out since November 2021.
2020 - I have now included Oak Crest, which was omitted by error due to it being sold in 2020, but registered in 2019.
2018 - I have now included the sale of Ashfield, which was recorded in all previous years.
Under directorship, the following applies:
2021 - I have now added RMT Management Limited. This was declared in previous years. I began the VSO process to close in 2020, and ceased operations in 2020. I was unaware that the process was not formally completed until 2021 hence my error.
Under land, the following applies:
2011 - 2021 I have now included all properties under land and occupation. Previously I had declared them under 'Occupation ', on advice from SIPO these should be declared secondly under 'Properties'.
2019 - I have now declared the sale of Ashlawn, Clonbalt Woods, Longford. This was omitted in error as the property was bought and sold that year.
2018 - I have now included the sale of Ashfield under land secondly as per the above advice.
While I understand the following information does not have to be declared, I have provided the following details to ensure full transparency:
I have at all times declared my 50% ownership of 39 Cathedral View Mullingar. During the course of my review, it was brought to my attention that this property is in fact registered in the sole name of the co-owner. That is clearly an error, and I will take the necessary steps now to have this corrected.
I have two Rental Accommodation Scheme (RAS) contracts with Westmeath County Council. I have disclosed details in relation to negotiations for potential sales of properties.
My now wife and then-girlfriend was a secretary of RMT Management Limited.
I held voluntary and non remunerative directorships with Westmeath Community Development and Mullingar Arts Centre - ending in 2011 and 2015 respectively.
I have provided details of the sale of the garden of one of my registered properties, 25 A Rathdown Road, in 2020.
I registered an inter-parliamentary trip to Taiwan in 2013. I participated in a Rent-a-Room scheme in 2019 in my private dwelling house.
