BEFORE YOU READ: This thread is not for debate on the morality or the legitimacy of our (our any) federal government's claim on our money. If you don't intend to pay your taxes, that's your cross to bear. Please keep the discussion related to tax advice and planning. Thank you!
Okay - We all know its coming. If you're converting it to USD, the IRS already knows about it. Let's swap ideas on how to set up logs of our gains and expenses so that when the time rolls around we're ready to file. I live in the US, so anything I say will naturally be related to that. Experts on the subject are highly encouraged to participate and correct errors or misconceptions. I am not such an expert.
Now, what I understand so far is that profit made by purchasing bitcoins low and selling them high qualifies as capital gains tax, which in normal situations is identical the income tax rate as indicated by the individual's income tax bracket.
Here's a simple example of what that could look like for you when you file in 2012, using 2011 tax rates;
If you are single, and you did very well for yourself, earning $60,000 for yourself through Bitcoin speculation, you'd fall into the bracket that owed $4750 + 25% of income over $34,500, which comes out to be $11,125, before deductions. If you used the standard deduction of $5,800 for single persons with no other benefits or bonuses, you'd owe a total of $5,325 to Uncle Sam. Of course there are many ways that individuals and corporations can pay less (and sometimes are forced to pay more!) than this example.
I have read that bitcoins held for over a year before being cashed in may qualify for long term capital gains rates, which are substantially lower. I don't have that kind of advanced tax knowledge to be certain of this. Does anyone know?
Another subject of particular interest to me, is that miners may be subject to very different rules. Can miners consider their bitcoins an asset produced as inventory, and would that mean different tax rules? Would a miner be able to consider rigs, equipment and power consumption as expenses for purposes of determining their net profit?
