A federal grand jury this week charged a 56-year-old Lafayette man with income tax fraud for allegedly failing to report hundreds of thousands of dollars in income, officials said.

Donald Domingues was indicted Wednesday on one count each of tax evasion and filing a false tax return, U.S. Attorney Stephanie Finley said.

Domingues reported $259,725 in income for 2007, and paid $64,909 in taxes, Finley said.

But the defendant failed to report a $351,000 sales commission he made that year, which would have upped his income to $610,725 and his tax liability to $185,959, Finley said.

If convicted, Domingues faces up to five years in prison and three years supervised release for tax evasion, and up to three years in prison and one year of supervised release for filing a false return, Finley said.

The IRS investigated the case that will be prosecuted by Assistant U.S. Attorney Howard C. Parker.
