He was bringing home a six-figure salary...so why didn't local doctor pay his taxes?

MILWAUKEE (WITI) -- A local doctor tells the IRS he didn't pay his taxes because he couldn't afford to -- even though he was making more than $100,000 a year! FOX6's Meghan Dwyer caught up with Dr. Michael Mangold outside the federal courthouse in Milwaukee on Thursday, May 22nd.

Meghan Dwyer: "I'm Meghan Dwyer with FOX6 News. Do you have a couple seconds to talk?"

Dr. Mangold: "Um, any of the plea agreement details? Not on camera."

Meghan Dwyer: "Not on camera? Why not?"

Dr. Mangold: "Well, I'm just shy."

Federal authorities say Mangold was anything but shy when it came to not paying his taxes.

Dr. Mangold: "It's all very complicated. You know, it took the government 16 years to come down on this."

Meghan Dwyer: "Why do you think that was?"

Dr. Mangold: "Because it's so complicated."

Mangold has been working at local hospitals, emergency rooms and urgent care centers since 1993. Federal authorities say from 1997 to 2007, he hid his wages from the IRS -- sometimes reporting zero income, even though he was bringing home a six-figure salary.

Meghan Dwyer: "Can you tell my why you decided to lie about your income?"

Dr. Mangold: "Oh, I didn't lie about my income."

Meghan Dwyer: "But you pleaded guilty today."

Dr. Mangold: "Yeah. Right. I did."

At one point, federal investigators say Mangold owed the IRS almost $200,000 in taxes and interest.

Dr. Mangold: "Am I on camera right now?"

Meghan Dwyer: "Yeah."

Dr. Mangold: "Oh, well you should actually talk to my lawyer."

Mangold has also admitted to lying about his income in order to get out of paying his student loans.

When asked to report his income, he only told the government about one of his jobs -- even though he was a doctor at multiple local clinics.

Most recently, Mangold practiced medicine in West Bend, and the now-shuttered Mangold Center for Family Wellness.

Meghan Dwyer: "Do you agree that you were actively trying to evade paying your taxes?"

Dr. Mangold: "Well, that's the thing that you'll have to talk to my lawyer about."

Mangold could get up to 10 years in prison for tax evasion and lying to the IRS.

He'll be sentenced in September.

The state revoked Mangold's medical license last year, but not because he failed to pay his taxes.

He can't practice medicine anymore because of unprofessional conduct with patients and bad record keeping.

He now lives in Illinois.
