A federal jury Friday found FedEx pilot Vernice Kuglin not guilty of evading income taxes on $920,000.
The question of tax payment was unresolved at the end of the five-day trial.
"I think it is safe to assume the IRS will attempt civil collection, but she is not guilty of tax evasion," said defense attorney Robert Bernhoft of Milwaukee.
"I feel justified," a grinning Kuglin said after the verdict was returned at mid--afternoon. She stood outside the federal building, chatting with supporters and jurors.
Federal prosecutor Joe Murphy was not available for comment.
Kuglin, 58, was charged with six counts of tax evasion that could have meant up to 30 years in prison and $1.5 million in fines.
The government accused Kuglin of filing false W4 forms for the period from 1996 to 2001.
Kuglin, a pilot for FedEx since 1985, said she had paid taxes like anyone else for most of her life. But about 10 or 11 years ago, she began to question the federal tax system.
