I am not a tax accountant. However, there seems to be a mix of state and local tax provisions here, and capital gains, personal income and business income tax law intertwined within in the responses. By the way, there is a story in the Wall Street Journal today that suggests that the federal income tax alone may be too complex to be constitutional.
All I will add to the mix is that the Obama health care bill enacted and signed into law last year has a provision that brought lots of complaints at the time; dealers in coins and precious metals will have to report transactions, SSN of the counter party, etc. to the IRS.
