Manco and Manco owners Charles and Mary Bangle entered their pleas Monday in federal court in Camden. They were charged earlier this month.
The government says the couple failed to report $980,000 in income from 2007 until 2011.
Charles Bangle is also accused of moving $340,000 over that span from the business accounts of the Ocean City-area shops to personal accounts in increments of less than $10,000. Authorities say that was done so the couple's bank would not be required to report the transaction.
A judge set a trial date for June, but it's expected it will be delayed.
