Hunter Biden has pled not guilty to all charges in the DOJ's case accusing the President's son of tax evasion.
As we reported, President Joe Biden's son was indicted last month on 9 charges, including failure to pay taxes, evasion of assessment, filing false or fraudulent tax returns ... and more.
Hunter made his first appearance in the case Thursday ... appearing before Judge Mark C. Scarsi, an appointee of former President Donald Trump, at the federal courthouse in downtown L.A.
He faces up to 17 years behind bars if convicted.
Special counsel David Weiss brought the case after an investigation involving Hunter's business dealings overseas.
Prosecutors claim Hunter spent millions on an extravagant lifestyle instead of paying his taxes.
As we reported, Hunter was indicted on separate gun charges back in Sept ... originally getting a plea deal for both the federal tax case and the gun situation.
But, the deal fell through after the judge questioned the terms of the arrangement.
