Could capital gains from a stock sale impact my IRA eligibility?
Yes, eligibility for contributing to a Roth IRA is determined by your Modified Adjusted Gross Income (MAGI) which is based on your Adjusted Gross Income (AGI). Now, AGI includes the net capital gains from your transactions and MAGI adds back in things that were subtracted off (e.g. tuition deductions, foreign earned income exclusion) in arriving at the AGI. There is a worksheet in Publication 590 that has the details. You are always entitled to contribute to a Traditional IRA. The MAGI affects how much of your contribution is tax-deductible on that year's tax return, but not your eligibility to contribute.  Both the above paragraphs assume that you have enough compensation (wages, salary, self-employment income) to contribute to an IRA: the contribution limit is $5500 or total compensation, whichever is smaller. (If you earned only $2K as wages, you can contribute all of it; not just your take-home pay which is what is left after Social Security and Medicare taxes, Federal taxes etc have been withheld from that $2K). If your entire income is from capital gains and stock dividends, you cannot contribute to any kind of IRA at all. Yes. Look at form 1040 AGI is line 37, and it comes well after you report your schedule D cap gains.  I read this question as meaning you wish to contribute to a traditional IRA pretax. There is no income limit to contribute to an IRA and not take the deduction.
"I recommend a Roth IRA. At your age you could turn 25K into a million and never pay taxes on these earnings. Of course there are yearly limits (5.5k) on the amount your can contribute to a Roth IRA account. If you haven't filed your taxes this year yet ... you can contribute 5.5K for last year and 5.5K for this year.  Open two accounts at a discount brokerage firm. Trades should be about $10 or less per. Account one ... Roth IRA. Account two a brokerage account  for the excess funds that can't be placed in the Roth IRA. Each year it will be easy transfer money into the Roth from this account. Be aware that you can't transfer stocks from brokerage acct to Roth IRA ... only cash. You can sell some stocks in brokerage and turn that into cash to transfer. This means settling up with the IRS on any gains/losses on that sale. Given your situation you'd likely have new cash to bring to table for the Roth IRA anyway. Invest in stocks and hold them for the long term. Do a google search for ""motley fool stock advisor"" and join. This is a premium service that picks two stocks to invest in each month. Invest small amounts (say $750) in each stock that they say you should buy. They will also tell you when to sell. They also give insights into why they selected the stock and why they are selling (aka learning experience).  They pick quality companies. So if the economy is down you will still own a quality company that will make it through the storm. Avoid the temptation to load up on one stock. Follow the small amount rule mentioned above per stock. Good luck, and get in the market." You are missing something very significant. The money in a traditional IRA (specifically, a deductible traditional IRA; there is not really any reason to keep a nondeductible traditional IRA anymore) is pre-tax. That means when you pay tax on it when you take it out, you are paying tax on it for the first time. If you take ordinary money to invest it in stocks, and then pay capital gains tax on it when you take it out, that is post-tax money to begin with -- meaning that you have already paid (income) tax on it once. Then you have to pay tax again on the time-value growth of that money (i.e. that growth is earned from money that is already taxed). That means you are effectively paying tax twice on part of that money. If that doesn't make sense to you, and you think that interest, capital gains, etc. is the first time you're paying tax on the money because it's growth, then you have a very simplistic view of money. There's something called time value of money, which means that a certain amount of money is equivalent to a greater amount of money in the future. If you invest $100 now and end up with $150 in the future, that $150 in the future is effectively the same money as the $100 now. Let's consider a few examples. Let's say you have $1000 of pre-tax income you want to invest and withdraw a certain period of time later in retirement. Let's say you have an investment that grows 100% over this period of time. And let's say that your tax rate now and in the future is 25% (and for simplicity, assume that all income is taxed at that rate instead of the tax bracket system). And capital gains tax is 15%. You see a few things: Traditional IRA and Roth IRA are equivalent if the tax rates are the same. This is because, in both cases, you pay tax one time on the money (the only difference between paying tax now and later is the tax rate). It doesn't matter that you're paying tax only on the principal for the Roth and on the principal plus earnings for Traditional, because the principal now is equivalent to the principal plus earnings in the future. And you also see that investing money outside fares worse than both of them. That is because you are paying tax on the money once plus some more. When you compare it against the Roth IRA, the disadvantage is obvious -- in both cases you pay income tax on the principal, but for Roth IRA you pay nothing on the earnings, whereas for the outside stock, you pay some tax on the earnings. What may be less obvious is it is equally disadvantageous compared to a Traditional IRA; Traditional and Roth IRA are equivalent in this comparison. 401(k)s and IRAs have a fundamental tax benefit compared to normal money investment, because they allow money to be taxed only one time. No matter how low the capital gains tax rate it, it is still worse because it is a tax on time-value growth from money that is already taxed. "I agree with Grade 'Eh' Bacon's answer, but there are a couple of ideas that are relevant to your particular situation: If I were you, I would invest at least half of the cash in growth ETFs because you're young enough that market variability doesn't affect you and long term growth is important. The rest should be invested in safer investments (value and dividend ETFs, bonds, cash) so that you have something to live off in the near term. You said you wanted to invest ethically.  The keyword to search is ""socially responsible ETFs"".  There are many, and if this is important to you, you'll have to read their prospectus to find one that matches your ethics. Since you're American, the way I understand it, you need to file taxes on income; selling stocks at a gain is income.  You want to make sure that as your stocks appreciate, you sell some every year and immediately rebuy them so that you pay a small tax bill every year rather than one huge tax bill 20 years from now.  Claiming about $20600 of capital gains every year would be tax free assuming you are not earning any other money.  I would claim a bit more in years where you make a lot. You can mitigate your long term capital gains tax exposure by opening a Roth IRA and maxing that out.  Capital gains in the Roth IRA are not taxable.  Even if you don't have income from working, you can have some income if you invest in stocks that pay dividends, which would allow you to contribute to a Roth IRA. You should figure where you're going to be living because you will want to minimize the currency risk of having your money in USD while you're living abroad.  If the exchange rate were to change by a lot, you might find yourself a lot poorer.  There are various hedging strategies, but the easiest one is to invest some of your money in securities of the country you'll be living in. You should look into how you'll be converting money into the foreign currency.  There are sometimes way of minimizing the spread when converting large amounts of money, e.g., Norbert's gambit.  Shaving off 1.5% when exchanging $100k saves $1500." "A qualifying distribution seems guaranteed to fall under long term capital gains. But a disqualifying distribution could also fall under long term capital gains depending on when it is sold. So what's the actual change that occurs once something becomes a qualifying as opposed to a disqualifying distribution? Yes a qualifying distribution always falls under long term capital gain. The difference between qualifying and disqualifying is how the ""bargain element"" of benefit is calculated. In case of disqualifying distribution it is always the discount offered, Irrespective of the final sale price of the stock. In case of qualifying distribution it is lower of actual discount or profit. Thus if you sell the stock at same price or slightly lower price than the price on exercise date, your ""bargain element"" is less. This is not the case with disqualifying distribution." Is that basically it? Trading off between withdrawing-anytime vs paying-capital-gain-tax? No. Another significant factor is dividends. In an IRA they incur no immediate tax and can be reinvested. This causes the account value to compound over the years. Historically, this compounding of dividends provides about half of the total return on investments. In a non-IRA account you have to pay taxes each year on all dividends received, whether you reinvest them or not. So outside of an IRA you have a tax drag on both capital gains and dividends. "There some specific circumstances when you would have a long-term gain. Option 1:  If you meet all of these conditions: Then you've got a long-term gain on the stock.  The premium on the option gets rolled into the capital gain on the stock and is not taxed separately.  From the IRS: If a call you write is exercised and you sell the underlying stock, increase your amount realized on the sale of the stock by the amount you received for the call when figuring your gain or loss. The gain or loss is long term or short term depending on your holding period of the stock. https://www.irs.gov/publications/p550/ch04.html#en_US_2015_publink100010630 Option 2: If you didn't hold the underlying and the exercise of the call that you wrote resulted in a short position, you might also be able to get to a long-term gain by buying the underlying while keeping your short position open and then ""crossing"" them to close both positions after one year. (In other words, don't ""buy to cover"" just ""buy"" so that your account shows both a long and a short position in the same security.  Your broker probably allows this, but if not you, could buy in a different account than the one with the short position.)  That would get you to this rule: As a general rule, you determine whether you have short-term or long-term capital gain or loss on a short sale by the amount of time you actually hold the property eventually delivered to the lender to close the short sale. https://www.irs.gov/publications/p550/ch04.html#en_US_2015_publink100010586 Option 1 is probably reasonably common.  Option 2, I would guess, is uncommon and likely not worthwhile. I do not think that the wash sale rules can help string along options from expiration to expiration though.  Option 1 has some elements of what you wrote in italics (I find that paragraph a bit confusing), but the wash sale does not help you out." You're asking whether the shares you sold while being a US tax resident are taxable in the US. The answer is yes, they are. How you acquired them or what were the circumstances of the sale is irrelevant. When you acquired them is relevant to the determination of the tax treatment - short or long term capital gains. You report this transaction on your Schedule D, follow the instructions. Make sure you can substantiate the cost basis properly based on how much you paid for the shares you sold (the taxable income recognized to you at vest). "Yes- you do not realize gains or losses until you actually sell the stock.  After you sell the initial stocks/bonds you have realized the gain.  When you buy the new, different stocks you haven't realized anything until you then sell those. There is one exception to this, called the ""Wash-Sale Rule"".  From Investopedia.com: With the wash-sale rule, the IRS disallows a loss deduction from the   sale of a security if a ‘substantially identical security' was purchased within 30 days before or after the sale.  The   wash-sale period is actually 61 days, consisting of the 30 days before   and the 30 days after the date of the sale. For example, if you bought   100 shares of IBM on December 1 and then sold 100 shares of IBM on   December 15 at a loss, the loss deduction would not be allowed.   Similarly, selling IBM on December 15 and then buying it back on   January 10 of the following year does not permit a deduction. The   wash-sale rule is designed to prevent investors from making trades for   the sole purpose of avoiding taxes."
