Original link: Hunter Biden enters guilty plea in federal tax case, avoiding a trial / NBC.
He must have realized that there was no pint in discussing guilt. The entire world knows that he spend his consulting income on alcohol, cocaine and prostitutes without paying taxes for 4 years. The trial is only a matter of what sentence he should get.
The maximum punishment of 17 years sound way off. The taxes did eventually get paid 4 years ago, so the tax authorities got their money way before the trial started. And for the main issue then he did not try to hide his income and file a fraudulent tax return - he just didn't file a tax return at all.
He may get more trouble for the fact that first attempt to file the tax returns had fraudulent deductions.
