Re: I didn't pay capital gains tax on bitcoin sales to IRS today
Ultimately it is "Not a Law" until the courts rule that it is. This is the "only place" laws are made. Keep that in mind 
In this case, the law authorizes the IRS to act as an 'agency' of the US Government. That agency is also empowered by the very same law to interpret the laws of Congress as appropriate.
oh really?
What law are you talking about?
