At tax time, what is the proper way to report cryptocurrency earnings and fiat income when you've started with “nothing”?
"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"
While you are required to do so as others have said, it's actually in your interest to do so. In a recent article at GlobeInvestor, Tim Cestnick discusses the benefits of filing tax returns for teens. This situation may or may not apply to you but the message is the same. The main benefits are (1) create RRSP contribution room and (2) be eligible for GST/HST credits and other possible one-shot credits (think oil royalty surplus cheques in Alberta). Excerpt: You see, when Lincoln was 14, he filed a tax return and reported $2,000 of income that year. He paid no tax thanks to the basic personal tax credit, but he created $360 of RRSP contribution room that year. Beginning in 2003, Lincoln started working part-time in his father's business. His father agreed to pay him $6,000 each summer to work in the business, to help save money for university. Lincoln didn't pay any tax on the money he earned in those summers because his basic personal tax credit was always higher than his earnings. In addition, Lincoln added to his RRSP contribution room simply by filing a tax return each year. As a new (very!) small business, the IRS has lots of advice and information for you. Start at https://www.irs.gov/businesses/small-businesses-self-employed and be sure you have several pots of coffee or other appropriate aid against somnolence.  By default a single-member LLC is 'disregarded' for tax purposes (at least for Federal, and generally states follow Federal although I don't know Mass. specifically), although it does have other effects. If you go this route you simply include the business income and expenses on Schedule C as part of your individual return on 1040, and the net SE income is included along with your other income (if any) in computing your tax. TurboTax or similar software should handle this for you, although you may need a premium version that costs a little more.  You can 'elect' to have the LLC taxed as a corporation by filing form 8832, see https://www.irs.gov/businesses/small-businesses-self-employed/limited-liability-company-llc . In principle you are supposed to do this when the entity is 'formed', but in practice AIUI if you do it by the end of the year they won't care at all, and if you do it after the end of the year but before or with your first affected return you qualify for automatic 'relief'. However, deciding how to divide the business income/profits into 'reasonable pay' to yourself versus 'dividends' is more complicated, and filling out corporation tax returns in addition to your individual return (which is still required) is more work, in addition to the work and cost of filing and reporting the LLC itself to your state of choice. Unless/until you make something like $50k-100k a year this probably isn't worth it. 1099 Reporting. Stripe qualifies as a 'payment network' and under a recent law payment networks must annually report to IRS (and copy to you) on form 1099-K if your account exceeds certain thresholds; see https://support.stripe.com/questions/will-i-receive-a-1099-k-and-what-do-i-do-with-it  . Note you are still legally required to report and pay tax on your SE income even if you aren't covered by 1099-K (or other) reporting. Self-employment tax. As a self-employed person (if the LLC is disregarded) you have to pay 'SE' tax that is effectively equivalent to the 'FICA' taxes that would be paid by your employer and you as an employee combined. This is 12.4% for Social Security unless/until your total earned income exceeds a cap (for 2017 $127,200, adjusted yearly for inflation), and 2.9% for Medicare with no limit (plus 'Additional Medicare' tax if you exceed a higher threshold and it isn't 'repealed and replaced'). If the LLC elects corporation status it has to pay you reasonable wages for your services, and withhold+pay FICA on those wages like any other employer. Estimated payments. You are required to pay most of your individual income tax, and SE tax if applicable, during the year (generally 90% of your tax or your tax minus $1,000 whichever is less). Most wage-earners don't notice this because it happens automatically through payroll withholding, but as self-employed you are responsible for making sufficient and timely estimated payments, and will owe a penalty if you don't. However, since this is your first year you may have a 'safe harbor'; if you also have income from an employer (reported on W-2, with withholding) and that withholding is sufficent to pay last year's tax, then you are exempt from the 'underpayment' penalty for this year.  If you elect corporation status then the corporation (which is really just you) must always make timely payments of withheld amounts, according to one of several different schedules that may apply depending on the amounts; I believe it also must make estimated payments for its own liability, if any, but I'm not familiar with that part. The Australian Tax Office website shows Tax Rates for individuals based on the income earned in the Financial Year. Calculating what you'll be taxed For instance, it show that every dollar you earn up to $18,200, you are not taxed. Every dollar over that, up to $37k is taxed at 19 cents. And so on.. Example 1 So as an example, if your income for the year is $25,000 you will be taxed $1292. Working: Here's how it's look if you were doing it in a spreadsheet using the Tax Rates table on the ATO website as a guide:  Example 2 If you income is $50,000, it'd look like this:  Withholding Your employer is obligated to remove the taxable part from your wage each time your paid. They do that using the calculation above.  If at the end of the financial year, the ATO determines that too much as been withheld (ie. you've claimed deductions that've reduce your taxable income to less than what your actual income is), that's when you may be eligible for a refund. If your employer didn't withhold enough or you had income from other sources that haven't been taxed already, then you may actually need to pay rather than expecting a refund. Your question If you earn $18,200 in the year and for some reason your employer did withhold tax from your pay, say $2,000, then yes, you'll get all that $2,000 back as a refund since the Tax Rate for income up to $18,200 is $0.00. If you earned $18,201 and your employer withheld $2000, you'd get $1999.81 back as a refund ($2000 - 19c). You have to pay 19c tax on that $1 over $18,200. "Welcome to the 'what should otherwise be a simple choice turns into a huge analysis' debate. If the choice were actually simple, we've have one 'golden answer' here and close others as duplicate. But, new questions continue to bring up different scenarios that impact the choice.  4 years ago, I wrote an article in which I discussed The Density of Your IRA. In that article, I acknowledge that, with no other tax favored savings, you can pack more value into the Roth.  In hindsight, I failed to add some key points. First, let's go back to what I'd describe as my main thesis: A retired couple hits the top of the 15% bracket with an income of   $96,700. (I include just the standard deduction and exemptions.) The   tax on this gross sum is $10,452.50 for an 'average' rate of 10.8%. The tax, paid or avoided, upon deposit, is one's marginal rate. But,   at retirement, the withdrawals first go through the zero bracket (i.e.   the STD deduction and exemptions), then 10%, then 15%. The above is the simplest snapshot. I am retired, and our return this year included Sch A, itemized deductions. Property tax, mort interest, insurance, donations added up fast, and from a gross income (IRA withdrawal) well into the 25% bracket, the effective/average rate was reported as 7.3%. If we had saved in Roth accounts, it would have been subject to 25%.  I'd suggest that it's this phenomenon, the ""save at marginal 25%, but withdraw at average sub-11%"" effect that account for much of the resulting tax savings that the IRA provides.  The way you are asking this, you've been focusing on one aspect, I believe. The 'density' issue. That assumes the investor has no 401(k) option. If I were building a spreadsheet to address this, I'd be sure to consider the fact that in a taxable account, long term gains are taxed at 15% for higher earners (I take the liberty to ignore  that wealthier taxpayers will pay a maximum 20% tax on long-term capital gains. This higher rate applies when your adjusted gross income falls into the top 39.6% tax bracket.) And those in the 10 or 15% bracket pay 0%. With median household income at $56K in 2016, and the 15% bracket top at $76K, this suggests that most people (gov data shows $75K is 80th percentile) have an effective unlimited Roth. So long as they invest in a way that avoids short term gains, they can rebalance often enough to realize LT gains and pay zero tax.  It's likely the $80K+ earner does have access to a 401(k) or other higher deposit account. If they don't, I'd still favor pretax IRAs, with $11K for the couple still 10% or so of their earnings. It would be a shame to lose that zero bracket of that first $20K withdrawal at retirement. Again working backwards, the $78K withdrawal would take nearly $2M in pretax savings to generate. All in today's dollars." "I'll add a bit to Paul's excellent write up. Foreign Earned Income Exclusion (form 2555): notice the earned there. It doesn't exclude capital gains, interest, dividends, and basically everything that is not salary. You pay US taxes on it from the first cent. Foreign tax credit - foreign tax credit (form 1116) doesn't reduce your US tax dollar for dollar (even though it may appear that it does from the generic explanations). By using this form you may end up accumulating unused credit while still paying double taxes at the same time. Happened to me. Thank Congress for the logical and reasonable US tax laws. New FATCA form 8938: as opposed to FBAR (that goes to the FinCEN in the Treasury), this one goes to the IRS. it contains very similar info, but the threshold requirements are different. You may have to file FBAR, but not these, or you may have to file both. Being an American citizen, some European banks will refuse to provide services to you. Again, thank Congress for FATCA. It requires foreign banks to enforce US tax regulations on US citizens, and banks that won't will get penalized in the US. Many banks refuse to provide services to Americans because of that because what IRS requires is illegal in most countries. Some countries (like UK and some other EU countries) have signed treaties with the US to resolve this, but many haven't. Currency conversion - as I commented to Paul, you convert the amounts when you receive them, which may have your fixed EUR salary be converted to different dollar amounts every time. You need to make sure you do it right. Pensions, savings, investments - if you're doing these in non-US instruments prepare to be penalized. US taxes foreign investments much more aggressively than domestic. If you're investing in indexes/mutual funds, or you're a principle in a corporation, or you create a pension account - you'll get hit by additional reporting requirements and tax. Tax treaties - the US has tax treaties with many EU countries, and equalization treaties with some. The tax treaties affect the standard tax treatment by the US and some of the ""generic"" info you got here may not apply because of a tax treaty, and some other rules may apply. Equalization treaties work similarly with regards to the Social Security. Bottom line, and I know Paul disagrees with me on this - talk with a US-licensed adviser in the country you're going to. It is very important for your tax adviser to know the relevant treaty (and not read it the first time when you call him), and to understand each and every financial instrument in your country. Missing piece of paper in your tax return can cost you thousands of dollars in penalties (not exaggerating, not filing form 3520 triggers a $10000 penalty, even if there's no tax) and additional taxes." The answer to this question requires looking at the mathematics of the Qualified Dividends and Capital Gains Worksheet (QDCGW). Start with Taxable Income which is the number that appears on Line 43 of Form 1040.  This is after the Adjusted Gross Income has been reduced by the Standard Deduction or Itemized Deductions as the case may be, as well as the exemptions claimed.   Then, subtract off the Qualified Dividends and the Net Long-Term Capital Gains (reduced by Net Short-Term  Capital Losses, if any) to get the non-cap-gains part of the Taxable Income. Assigning somewhat different meanings to the numbers in the OPs' question, let's say that the Taxable Income is $74K of which $10K is Long-Term Capital Gains leaving $64K as the the non-cap-gains taxable income on Line 7 of the QDCGW.   Since $64K is smaller than $72.5K (not $73.8K as stated by the OP) and this is a MFJ return, $72.5K - $64K = $8.5K of the long-term capital gains are taxed at 0%. The balance $1.5K is taxed at 15% giving $225 as the tax due on that part.   The 64K of non-cap-gains taxable income has a tax of $8711 if I am reading the Tax Tables correctly, and so the total tax due is $8711+225 = $8936.  This is as it should be; the non-gains income of $64K was assessed the tax due on it, $8.5K of the cap gains were taxed at 0%, and $1.5K at 15%. There are more complications to be worked out on the QDCGW for high earners who attract the 20% capital gains rate but those are not relevant here. "As cryptocurrencies are rather new compared to most assets, there hasn't been a lot of specific guidance for a lot of situation, but in 2014 the IRS announced that it published guidance in Notice 2014-21. I'm not aware of further guidance that has been published beyond that, though it wouldn't surprise me if treatments changed over time. In that notice, the answer to the first question describes the general treatment: For federal tax purposes, virtual currency is treated as property. General tax principles applicable to property transactions apply to transactions using virtual currency. Your specific questions (about what constitutes a ""business"", and when you're considered to be ""selling"" the cryptoproperty) are likely to be considered on a case by case basis by the IRS. As the amounts involved here are so small (relatively speaking), my recommendation would be to read through what the IRS has published carefully, make reasonable assumptions about what scenarios that are described are closest to what you're doing, and document doing so clearly as part of your tax preparations. And when in doubt, erring on the side of whichever option incurs more tax is unlikely to be objected to by them. Of course, I'm not a lawyer or tax advisor, I'm a stranger on the Internet, so for ""real"" advice you should contact somebody qualified. I doubt you'd be faulted too much for not doing so given the amounts involved. You could also attempt contacting a local IRS office or calling them with your specific questions, and they may be able to provide more specific guidance tailored to you, though doing so may not save you from an auditor deciding something differently if they were to examine your return later. There are also phone numbers to contact specific people listed at the end of Notice 2014-21; you could try calling them as well." If you hold this money in USD and spend it in the US as USD, then there is no tax liability or reporting requirement at all.  You are not subject to any tax on foreign exchange gains and losses because you have not performed any foreign exchange.  CRA says a foreign exchange gain or loss happens when the fx transaction occurs—not as the currency’s value fluctuates while on deposit - and since you are never performing an fx transaction, no such issues will arise.  The CRA is not interested in how you spend your money, only the money that you earn.   The only possible tax liability that would arise in the circumstances that you describe would be the tax liability arising from interest earned while the cash in on deposit.  If this interest exceeds the threshold of reportability, then your bank will issue you with a T-slip to be included in your tax return.
