I just keep thinking, if I was running a lemonade stand or knitting scarves at a LOSS would I really bother reporting it to the IRS? It's not like I'm skipping on owing them anything, not to mention the ridiculous detail involved in daily payouts on my spreadsheets.
My thinking on this exact question is that establishing the basis now as legitimately as possible should reduce problems with any future capital gains (hopefully!).
I know, famous last words right?
I'm personally not too concerned about the record-keeping, unless there's some compelling information I'm not privy to yet, because it seems insane that the IRS would get so granular as to scrutinize pool shifts. I'm figuring just settling the amount mined by day and extending by say a Coinbase quote for that day would be perfectly fine for establishing basis. That's already kind of insane, but the wording of the guidance kind of suggests to me that would be the right approach. Admittedly this is pretty trivial to track just with very basic relational database proficiency, spreadsheet lookups, or very simple coding.
I'm tempted to just write a quick and dirty python script that does this straight off the CSV Bitcoin-qt can dump, assuming the Coinbase API has a function for historical lookups via HTTP GET (?). If anybody thinks that might be useful I'll post the script if I actually do that.
I went to
http://bitcoincharts.com/charts/btceUSD#rg180ztgSzm1g10zm2g25zv and clicked "load raw data"- the column all the way to the right is the day's weighted average price and that is what I used for payouts. I'm just making spreadsheets to get a better idea of how this looks before I make any decisions. I am trying to get a hold of a CPA but I'm almost certain that the mention of Bitcoin has scared them off. Left to my own devices I might not report but will keep my detailed records ready for next year. I only had 2 months of mining in 2013 so that's not really my concern as much as 2014 will be.
My problem is I've got all these 0.05 payouts, and it's around one per day. Each one is converted to USD, but along the way I was spending BTC on new mining gear. The IRS is expecting me to treat each time I bought gear to be a sale, but my cost basis tax lots are 0.05BTC each!! So if I'm using a FIFO method that would mean my first whole bitcoin spent would come from the first 20 payouts- trying to make a running system with daily payouts and fractional spending is f'ing insane. I'll need to find a way to maybe just take my annual average cost basis and say "good enough". That method might even be allowed, I mean non-public companies don't need to worry about GAAP requirements, pretty sure we can determine a reasonable method be it LIFO, FIFO, or average cost so long as we stick with it.
Lastly, I was chatting on a fairly popular chat room tonight about this. Everyone there was basically saying I am insane for even considering filing my mining income. Seems the general vibe on the forums here is much different than the pool chat rooms. I wonder what the casual mining non-message-board-addict is thinking. The only moment I started getting worried was when I read these forums and saw all the panic.
