The owner of Tammy's Tax Service in Moncks Corner is accused of filing bogus tax returns to obtain fraudulent refunds for her clients.

Investigators from the state Department of Revenue arrested Tammy Brinson on Wednesday. She is charged with nine counts of willfully assisting in the preparation of false or fraudulent tax returns, according to Samantha Cheek, the Revenue Department's spokeswoman.

For tax years 2007 and 2008, Brinson met with clients and filed income tax returns in their names with fraudulent information, Cheek said. The clients, who received improper refunds, were unaware that Brinson was doing anything wrong, she said.

The Revenue Department would not say how much money was involved in the bogus refunds.

Brinson did not return a phone call to her office Thursday. But she shared her opinions on the state charges in a post made to her Facebook page.

"Tax man can try and bully me, but i will always fight for my clients and see to it that they get what they pay for!" she wrote. "Its unfortunate that some lied to me and i have to face this madness but it will be ok. Truth always prevails!"

Investigators still are trying to determine the motive for Brinson's actions, Cheek said.

In some cases, unscrupulous tax preparers try to drum up business by falsely promising that they can get the filer a larger refund than their competitors, Cheek said. Others try to inflate the refund because their fee is based on the amount of money their clients get back, she said.

If convicted, Brinson could face up to 45 years in prison and/or $4,500 in fines, Cheek said.
