The EU's statistics agency, Eurostat, has said regular visits to member states to confirm national accounts such as GDP are standard practice.
This follows a report in today's Irish Times stating Eurostat is sending a team to Dublin next month to investigate Irish economic growth figures for 2015, which were abnormally high.
Last month the Central Statistics Office reported a 26% jump in Ireland's Gross Domestic Product in 2015, much of which was caused by aircraft purchases, corporate restructuring and companies re-locating assets to Ireland.
Reports on Eurostat's planned visit cited an internal document at the European agency, which said Ireland's explanations for an exceptionally high GDP figure of 26% last year "look plausible" but the agency wanted to conduct its own verification process.
In a statement to RTÉ News, Eurostat said: "Visits to member states are a standard part of the GNI verification procedure. As a matter of principle, Eurostat does not comment on such visits."
The CSO also described the planned visit as "routine" and said it was part of Eurostat's process of verification.
"Eurostat has held intensive discussions with the CSO on the changes to our National Accounts and Balance of Payments statistics driven by the location of capital assets in Ireland and accepts the recent GDP revisions," said Jennifer Banim, assistant director general at the CSO.
"The purpose of the planned visit is final verification".
The CSO said the figures were gathered in accordance with standards set by the United Nations and International Monetary Fund and accurately reflected the "complex and highly globalised nature of the Irish economy".
However Ms Banim added that the recent revisions also highlighted a challenge for bodies like the CSO, and how reliable GDP figures are in identifying the actual economic performance of an open, globalised country like Ireland.
She pointed out that the CSO had recently convened a cross sector group to try to address this in the future and provide a better insight into the state of the domestic economy.
Separately, the Department of Finance confirmed its chief economist John McCarthy will be part of that consultative group.
