A trawl of construction companies by the Revenue Commissioners yielded a total of €154m last year.
The figure is included in preliminary business figures published today.
Revenue conducted 3,807 audits of construction firms in 2007 which saw building companies pay a total of €129m in interest, tax and penalties.
In addition it conducted 40,000 assurance checks when documents indicated there could be unusual activity in certain transactions.
These checks yielded a further €21m.
