Are these scenarios considered as taxable income?
For case 1, there is no tax due as you sold the book for less than your cost basis. If you had sold for more than $100, then you would have had a profit. For case 2, that depends on the value of the gift card with respect to the value of your fare. Most likely that gift card is less than the cost of the fare. And in that case it would generally be treated as a reduction in the purchase price. The same way that rebates and cash back on credit card are treated. Note if for some reason a 1099 was generated that would change the situation and you would need to consult a tax professional. Since that would indicate that the other party to the transaction had a different view of the situation. You can always reduce the income by the direct expenses required to earn it, and figure out whether it is ultimately a net profit or loss.   The net profit is taxable income.  The loss may be tax deductible if the underlying thing is tax deductible.    For the book, the $50 revenue required a $100 expense, so that's a $50 net loss.  You don't owe any income tax since it's a loss.  You could take the loss as a tax deduction if you have a business trading books, or if buying the book would be tax deductible for some reason.  Note that in the latter case you can only deduct the $50 not the $100.  For the airline ticket, it is to compensate you for the losses you took as a result if the delayed flight. So you tally up the $22 meal you had in the airport waiting for news, the $110 on the motel room you rented or forfeited, any other way you can peg a cash value to any losses you took.  Total them up, again, a net loss is only deductible if the travel is already deductible. Note that if the actual expenses (book, flight) were tax deductible for some reason, the cash-back reduces the amount of your tax deduction, so it has the same effect as the sale/gift being taxable income.
"Yes, this is a miscellaneous itemized deduction. https://www.irs.gov/publications/p529/ar02.html For this to impact your taxes, you have to be itemizing deductions (have total deductions greater than standard deduction), and the total of all miscellaneous deductions needs to exceed the ""2% floor"" described in the IRS link above." "What theyre fishing for is whether the money was earned in the U.S.  It's essentially an interest shelter, and/or avoiding double taxation.   They're saying if you keep income you make outside the US in a bank inside the US, the US thanks you for storing your foreign money here and doesn't tax the interest (but the nation where you earned that income might).   There is no question that the AirBNB income is ""connected with a US trade or business"".   So your next question is whether the fraction of interest earned from that income can be broken out, or whether IRS requires you to declare all the interest from that account.   Honestly given the amount of tax at stake, it may not be worth your time researching.   Now since you seem to be a resident nonresident alien, it seems apparent that whatever economic value you are creating to earn your salary, is being performed in the United States. If this is for an American company and wages paid in USD, no question, that's a US trade or business. But what if it's for a Swedish company running on Swedish servers, serving Swedes and paid in Kroner to a Swedish bank which you then transfer to your US bank? Does it matter if your boots are on sovereign US soil?  This is a complex question, and some countries (UK) say ""if your boots are in our nation, it is trade/income in our nation""... Others (CA) do not.  This is probably a separate question to search or ask. To be clear, the fact that your days as a teacher or trainee do not count toward residency, is a separate question from whether your salary as same counts as US income." "The answer to your first question is true. No tax on withdrawls. Under these circumstances, the withdrawl is ""qualified"". To your second question, as long as the withdrawl is qualified, it is not taxed, regardless of your additional income. http://www.investopedia.com/articles/retirement/03/030403.asp?lgl=rira-baseline-vertical has a very comprehensive, plain English, description of the IRS rules (as of today, anyway)." A stipend received for the specific purposes of studies is not taxable. It is not clear from your question as to whether there are any strings attached to the money you receive. If its not for specific purpose, then its taxable as income and tax need to be paid accordingly. Please consult a CA and he can go through the specifics of your case. "In the Income Statement that you've linked to, look for the line labeled ""Net Income"". That's followed by a line labeled ""Preferred Dividends"", which is followed by ""Income Available to Common Excl. Extra Items"" and ""Income Available to Common Incl. Extra Items"". Those last two are the ones to look at. The key is that these lines reflect income minus dividends paid to preferred stockholders (of which there are none here), and that's income that's available to ordinary shareholders, i.e., ""earnings for the common stock""." I'm not sure I am fully understanding the nuance of your question, but based on your answer in the comments you and your business are not separate legal entities. So your income is the full $70K, there is no distinct business to have income. If you clarify your question to include why you want to know this I might be able to give a more meaningful answer for your situation. "Taxability depends on residential status when the $ were earned. If it was earned during his status as ""Non-Resident"" in India, then its tax free. If the money was earned when his tax status was resident in India, then its taxable as per the tax bracket. Edit: Taxability does not depend on whether to transfer the money into India, or keep it out of India or bring it as Cash or Electronically. It only depends on NRI status. Of course transferring the funds into NRE makes the paperwork simpler in case there is a scrutiny." The IRS defines income quite specifically. On the topic What is Taxable and Nontaxable Income, they note: You can receive income in the form of money, property, or services. This section discusses many kinds of income that are taxable or nontaxable. It includes discussions on employee wages and fringe benefits, and income from bartering, partnerships, S corporations, and royalties.  Bartering, or giving someone wages (or similar) in something other than currency (or some other specifically defined things, like fringe benefits), is taxed at fair market value: Bartering Bartering is an exchange of property or services. You must include in your income, at the time received, the fair market value of property or services you receive in bartering. For additional information, Refer to Tax Topic 420 - Bartering Income and Barter Exchanges. Bartering is more specifically covered in Topic 420 - Bartering Income: You must include in gross income in the year of receipt the fair market value of goods or services received from bartering. Generally, you report this income on Form 1040, Schedule C (PDF), Profit or Loss from Business (Sole Proprietorship), or Form 1040, Schedule C-EZ (PDF), Net Profit from Business (Sole Proprietorship). If you failed to report this income, correct your return by filing a Form 1040X (PDF), Amended U.S. Individual Income Tax Return. Refer to Topic 308 for information on filing an amended return. More details about income in general beyond the above articles is available in Publication 525, Taxable and Nontaxable Income.  It goes into great detail about different kinds of income. In your example, you'd have to calculate the fair market value of an avocado, and then determine how much cash-equivalent you were paid in.  The IRS wouldn't necessarily tell you what that value was; you'd calculate it based on something you feel you could justify to them afterwards.  The way I'd do it would be to write down the price of avocados at each pay period, and apply a dollar-cost-averaging type method to determine the total pay's fair value.   While the avocado example is of course largely absurd, the advent of bitcoins has made this much more relevant.  Publication 525 has this to say about virtual currency: Virtual Currency.   If your employer gives you virtual currency (such as Bitcoin) as payment for your services, you must include the fair market value of the currency in your income. The fair market value of virtual currency (such as Bitcoin) paid as wages is subject to federal income tax withholding, Federal Insurance Contribution Act (FICA) tax, and Federal Unemployment Tax Act (FUTA) tax and must be reported on Form W-2, Wage and Tax Statement. Gold would be fundamentally similar - although I am not sure it's legal to pay someone in gold; assuming it were, though, its fair market value would be again the definition of income.  Similarly, if you're paid in another country's currency, the US dollar equivalent of that is what you'll pay taxes on, at the fair market value of that currency in US dollars. Form 1099-misc reports PAYMENTS, not earnings.  This does not imply the EARNINGS are not taxable in the year they were earned. "Context: My parents overseas (Japan) sent me a little over $100,000 to   cover an expensive tuition payment and moderate living expenses in   2014. They are not US residents, Green card holders or citizens. They did not remit the tuition payment directly to the school. I am a   resident (for tax). This is enough to answer yes. That's basically the set of requirements for filing: you received >$100K from a non-US person and you yourself are a US person. You have to report it, and unless it is taxable income - it is a gift. Taxable income is reported on the form 1040, gifts are reported on the form 3520. The fact that in Japan it is not considered a gift is irrelevant. Gift tax laws vary between countries, some (many) don't have gift taxes at all. But the reporting requirement is based on the US law and the US definition of ""gift"". As I said above, if it is not a gift per the US law, then it is taxable income (and then you report all of it regardless of the amount and pay taxes). Had they paid directly to the institution, you wouldn't need to count it as income/gift to you because you didn't actually receive the money (so no income) and it went directly to cover your qualified education expenses (so no gift), but this is not the case in your situation. Whether or not this will be reported by the IRS back to Japan - I don't know, but it was probably already reported to the authorities in Japan by the banks through which the transfers went through. As to whether it will trigger an audit - doesn't really matter. It was, most likely, reported to the IRS already by the receiving banks in the US, so not reporting it on your tax return (either as income or on form 3520) may indeed raise some flags." "Not sure I understood, so I'll summarize what I think I read: You got scholarship X, paid tuition Y < X, and you got 1098T to report these numbers. You're asking whether you need to pay taxes on (X-Y) that you end up with as income. The answer is: of course. You can have even lower tax liability if you don't include the numbers on W2, right? So why doesn't it occur to you to ask ""if I don't include W2 in the software, it comes up with a smaller tax - do I need to include it?""?" You only need to report INCOME to the IRS. Money which you are paying to a landlord on behalf of someone else is not income. As Victor says, you pay tax on net profit. If this is a significant source of income for you, you should file quarterly estimated tax payments or you're going to get hit with a penalty at the end of the year. It should be reported as Miscellaneous Income. Congratulations for wanting to report this income. The argument seems to derive from the fact that state law bars cities from taxing net income. Hence the city is arguing it doesn't apply to gross income. Of course the city would also have to argue that income isn’t property. I don't think it's going to work out for them.
