Sixty-year-old John Karoly Jr. would serve 10 years if federal prosecutors get their way.
But the defense says Karoly is losing his law license and his reputation, and should not be harshly punished.
Karoly pleaded guilty to evading taxes on $5 million in income.
A judge later found him guilty of fraud and money laundering.
Karoly had steered a $500,000 donation he made to the Lehigh Valley Community Foundation to his church - which forwarded most of it back to Karoly.
Karoly admitted on the stand he used that money for office expenses, clothing, pet care and catering costs for his brother's funeral.
