The Revenue Commissioners’ office yesterday launched a blitz against small businesses across the county including Letterkenny.
A number of small firms across the town were raided as part of a tax compliance operation.
Employees in a number of small businesses were interviewed and asked for their employment details including PPS numbers.
Among the premises visited by the Revenue was the CoLab building at Letterkenny’s Institute of Technology.
A number of officers from Revenue called to the campus to carry out an audit of firms there.
The CoLab is made up of small, start-up companies.
The owners of various small businesses were interviewed as part of a general investigation.
The latest raids are part of an overall step-up in operations by Revenue.
Last month, officers raided at least two building sites around the town and interviewed a number of construction workers on site.
Details of workers conditions of employment including RSI numbers were sought.
