(Waupun) A Waupun woman has pled guilty to federal tax fraud charges. Kimberly Bagneski prepared and filed false tax returns to the IRS with fictitious claims for refunds.

On the returns, the 48-year-old claimed false deductions, tax credits and business income/losses.

Bagneski faces up to five years in prison and fines of up to $250,000 when she is sentenced in June.
