Back in 2011 I started mining Bitcoin. I earned no more than .75 BTC. At that time, it was worth no more than $0.75. I began to trade my bitcoins for alt-coins.

Regarding taxes and cryptocurrencies it is, and has always been, my intent to handle these funds properly at tax time. Back in 2011-2013, there were practically no US tax guidelines, so I didn't report anything to my taxes since I never cashed out my cryptocurrency for fiat. However, around 2014 I started cashing out some of my Bitcoin profits. Each year I've entered this on my tax records as 100%, capital gains. For example, if I sold 5 BTC at $500/each in a given year, I'd report the $2,500 as $2,500 capital gains.

Here is my primary question, if I've not spent a single dime on cryptocurrency, and my initial BTC "seed" was so small it wouldn't have even appeared on my taxes for 2011, am I properly handling my taxes when I cash out my BTC?

Also, I still hold a moderate amount of cryptocurrency. Since I'm not exchanging it back-and-forth for fiat, do I need to ever report it or is it legitimately some form of indeterminate asset that has no taxable value until I cash it into fiat cash?

The bottom line is that since I paid practically nothing for my original trading "seed" funds, do special rules apply when I do my taxes, especially in regards to assets I currently hold year over year?

    I think the term you're looking for here is "basis" or "cost basis". Regardless of wether you invested in BTC, ETH, stock, potatoes, dogs, or exotic cheese I think you'd use similar formulae to compute what the net profits are for tax purposes. – Freiheit Oct 12 '17 at 12:56

In 2014 the IRS announced that it published guidance in Notice 2014-21. In that notice, the answer to the first question describes the general tax treatment of virtual currency:

For federal tax purposes, virtual currency is treated as property. General tax principles applicable to property transactions apply to transactions using virtual currency.

As it's property like any other, capital gains if and when you sell are taxed. As with any capital gains, you're taxed on the "profit" you made, that is the "proceeds" (how much you got when you sold) minus your "basis" (how much you paid to get the property that you sold). Until you sell, it's just an asset (like a house, or a share of stock, or a rare collectible card) that doesn't require any reporting.

If your initial cryptocurrency acquisition was through mining, then this section of that Notice applies:

Q-8: Does a taxpayer who “mines” virtual currency (for example, uses computer resources to validate Bitcoin transactions and maintain the public Bitcoin transaction ledger) realize gross income upon receipt of the virtual currency resulting from those activities?

A-8: Yes, when a taxpayer successfully “mines” virtual currency, the fair market value of the virtual currency as of the date of receipt is includible in gross income. See Publication 525, Taxable and Nontaxable Income, for more information on taxable income.

That is to say, when it was mined the market value of the amount generated should have been included in income (probably on either Line 21 Other Income, or on Schedule C if it's from your own business). At that point, the market value would also qualify as your basis. Though I doubt there'd be a whole lot of enforcement action for not amending your 2011 return to include $0.75. (Technically if you find a dollar bill on the street it should be included in income, but usually the government cares about bigger fish than that.)

It sounds like your basis is close enough to zero that it's not worth trying to calculate a more accurate value. Since your basis couldn't be less than zero, there's no way that using zero as your basis would cause you to pay less tax than you ought, so the government won't have any objections to it.

One thing to be careful of is to document that your holdings qualify for long-term capital gains treatment (held longer than a year) if applicable.

Also, as you're trading in multiple cryptocurrencies, each transaction may count as a "sale" of one kind followed by a "purchase" of the other kind, much like if you traded your Apple stock for Google stock. It's possible that "1031 like kind exchange" rules apply, and in June 2016 the American Institute of CPAs sent a letter asking about it (among other things), but as far as I know there's been no official IRS guidance on the matter. There are also some related questions here; see "Do altcoin trades count as like-kind exchanges?" and "Assuming 1031 Doesn't Apply To Cryptocurrency Trading". But if in fact those exchange rules do not apply and it is just considered a sale followed by a purchase, then you would need to report each exchange as a sale with that asset's basis (probably $0 for the initial one), and proceeds of the fair market value at the time, and then that same value would be the basis of the new asset you're purchasing.

Using a $0 basis is how I treat my bitcoin sales, though I haven't dealt with other cryptocurrencies. As long as all the USD income is being reported when you get USD, I find it unlikely you'll run into a lot of trouble, even if you technically were supposed to report the individual transactions when they happened. Though, I'm not in charge of IRS enforcement, and I'm not aware of any high-profile cases, so it's hard to know anything for sure.

Obviously, if there's a lot of money involved, you may want to involve a professional rather than random strangers on the Internet. You could also try contacting the IRS directly, as believe-it-or-not, their job is in fact helping you to comply with the tax laws correctly. Also, there are phone numbers at the end of Notice 2014-21 of people which might be able to provide further guidance, including this statement:

The principal author of this notice is Keith A. Aqui of the Office of Associate Chief Counsel (Income Tax & Accounting). For further information about income tax issues addressed in this notice, please contact Mr. Aqui at (202) 317-4718

    I believe that OP made his money trading BTC as opposed to mining it. Is the basis still zero if the BTC was earned by mining? Mining has costs for hardware, electricity, software, etc. – Freiheit Oct 12 '17 at 14:02

    @Freiheit: That's starting to sound like a separate question, but there's info on mining in that IRS Notice 2014-21. Mining counts as income at fair market value at the time of mining (which if it's your business you could probably deduct expenses for), and that value becomes the basis for that asset. A sale of that asset would have the capital gain or loss on the change in value between that time you mined it and the sale. – user42405 Oct 12 '17 at 14:08
  • @PeterCooperJr. Freiheit is correct. In my case, I've been trading cryptocurrencies (but not fiat) back and forth for years. This is the essence of setting up my background (which was edited out.) Is my bases 0, still, if I've traded currency A for B in one year, then currency B for C in another year and, finally, currency C back to A this year, before selling A for USD? This is hard to document. Maybe I need to start, but I'd consider my gains "short term" since the trade-actions are more recent, but I could be wrong. I started with nothing, so when does my short/long-term begin? – RLH Oct 12 '17 at 15:05

    @RLH Every time you trade one e-currency for another, it is a taxable event, even if you didn't change it to "fiat money". If you traded someone your Apple shares for IBM shares, that would be a taxable event. This is no different. – Grade 'Eh' Bacon Oct 12 '17 at 15:25

    There, I've added a bit more on mining income, cryptocurrency exchanges, and who else you might be able to contact. – user42405 Oct 12 '17 at 16:04

You did not start with "nothing" unless you were accidentally paid a sum. Even if you scam or steal it, there are overheads.

You mined, therefore you had plant/capital assets. You paid for the electricity unless you had a free supply. This may include air conditioning. You may have had Internet charges. All these things contribute to the base cost, which in turn will reduce your imputed income or loss (the gap when compared to fair market value). You may have had to write off (not just depreciate) hardware. 0.75? If you were part of a pool, your calculations may need to be geared due to the factored nature of the payout. It is going to be hard after 7 years to arrive at the true base cost. You likely acquired it at a loss.

A lot of people mine at a loss. A lot.

In your jurisdiction, you will likely need an accountant. Particularly if you spend the currency you would need to know the dollar equivalent as well as the fee structure. If a game on Steam is $5.00 on Sale, you are not bartering for a value of $79.99.

  • I don't disagree but with this assessment but knowing a few factors of my setup, the costs were negligible. I used hardware I'd already owned and since it was the tail end of CPU mining days, my electrical costs were minimal-- maybe an additional $5-10/mo. All-in-all, I probably spent no more than $50 on my early crypto, and that's a liberal stretch on cost. – RLH Jan 30 '18 at 17:29
  • Fair enough, not something I would have published, as generally you want every deduction you are "entitled" to, but by all means include that figure as it is certainly reasonable. – mckenzm Jan 30 '18 at 22:51
  • The cost of mining cannot be added to the basis of the currency mined. If you are running the mining as a business, it is deductible in the year spent. If you are mining as a hobby, as it appears the OP was, you can only deduct expenses up to gross income ($0.75, by his estimate). In either case, the time to take advantage of that is long past for him. – prl May 9 '18 at 9:08
