Federal agents arrested Hawaii island resident Sherilyn K. Wahinekapu Monday morning on charges that she filed six fraudulent tax returns, falsely claiming refunds, for tax years 2006 through 2008.

Wahinekapu, 60, was arraigned Monday and pleaded not guilty Monday in U.S. District Court in Honolulu, the U.S. Attorney’s Office said.

A federal grand jury indicted her April 12 on six counts of making a false claim against the government. Trial is scheduled to begin June 13.

Florence T. Nakakuni, U.S. attorney for Hawaii, said Wahinekapu knowingly claimed false refund amounts ranging from $40,941 to $1,652,187.

Each count carries a penalty of up to five years in prison and a fine of up to $250,000.
