Criminal investigators from the HM Revenue and Customs (HMRC) arrested two men in Co Down and another in Co Armagh on Thursday.
Three properties were searched and investigations are continuing.
Two men, aged 20 and 49, were detained in Newry, Co Down and a 54-year-old man was arrested in Keady, Co Armagh.
John Whiting, HMRC's assistant director of criminal investigation, said: "We take tax fraud extremely seriously and will not hesitate to investigate those suspected of stealing public funds at the expense of the taxpayer."
The men have been bailed to various dates in September pending further inquiries.
