My accountant has advised me that I should report these as "Other Income" for my Mining/Arbitrage/Trading LLC I set up in 2012, which basically means Bitcoins are taxed at the highest rate possible (akin to an increased salary). I might even have to pay more in Social Security tax, we still don't know.
Until we get clarity from the gov't on this, I'm going with my accountant and taking as legal of a route as possible. If cryptocurrencies do get taxed at lower rates, then I can always go back and file a claim for what they owe me. I do agree that these should be taxed at capital gains rates, but capital gains have very specific designations in the tax code (or so I'm told) and because the IRS is slacking off, we presently think that Bitcoins fall under Other Income at the present time. I don't think more familiar CPAs are going to be universal in their assessment of this, so take what I have to say here as you may. I'm just going the extra precautionary route though I'm definitely complaining every step of the way. Also, this $50k I made was a sale of only a small portion of my holdings, so this is kind of a "let's figure out what happens" sort of thing.
Also, because of the sharp contrast in my previous to my present bank account standings, I'm sure to get audited, so I imagine I'll have a lot to say to the IRS about this as well. This is partially the reason for why I was thinking of doing a blog, so I can complain about everything that happens and how unfairly I'm sure to get targeted. Maybe they'll surprise me and it'll be a cheery process or there won't be an audit at all. I find both unlikely.
TLDR; I'm going to be a shining beacon of the opposite that I want to be regarding taxes on cryptocurrencies. If the feds screw around with me, I'm leaving this god-forsaken bananapetrodollar republic and making sure they don't make another dime off of me and no one will be able to say I didn't try to work with them on this.
I'm right behind you brother. If I get any sort of pushback by the IRS I will move out as well. I have friends in Thailand who say I can get a flat in a tower on the ocean for $1000/month. I'll just move into my friend's building and hang out with Thai supermodels.
What you say about talking to an accountant of course makes sense and I would suggest anyone who is going to spend any of their bitcoin loot to do the same. I plan to use mine for a down payment on a house. I want to diversify my investments from just bitcoin to bitcoin and real estate in case my bitcoin holdings drop because of some unforeseen news.
Yes, I will have to declare some of my gains in taxes but I hope to offset those with mortgage interest payments.
