US: Basics of taxation of stocks
E.g. I buy 1 stock unit for $100.00 and sell it later for $150.00 => income taxes arise. Correct. You pay tax on your gains, i.e.: the different between net proceeds and gross costs (proceeds sans fees, acquisition costs including fees). I buy 1 stock unit for $150.00 and sell it later for $100.00 => no income taxes here. Not correct. The loss is deductible from other capital gains, and if no other capital gains - from your income (up to $3000 a year, until exhausted). Also, there are two different tax rate sets for capital gains: short term (holding up to 1 year) and long term (more than that). Short term capital gains tax matches ordinary income brackets, whereas long term capital gains tax brackets are much lower.
A purchase of a stock is not a taxable event. No 1099 to worry about.  Welcome to Money.SE Some companies like Royal Dutch Shell have multiple share classes to suit the tax regimes in Holland and the UK the A shares have dutch withholding tax applied and the B shares dont.  Also some split capital investment trusts have multiple share classes http://www.trustnet.com/Education/Split.aspx?ms=1 Assuming the stock was worth more at the time she gave it to you than when she bought it, the cost basis would be the amount that she bought it for. You would then pay tax on the increase in value from that time.  Generally it's better to inherit assets than receive them as gifts, since the cost basis of inherited assets is raised to the value at the time of the death of the one leaving the inheritance. You will probably need to find some record of the original amount paid so you can determine the right cost basis. My understanding is that when you die, the stocks are sold and then   the money is given to the beneficiary or the stock is repurchased in   the beneficiaries name. This is wrong, and the conclusion you draw from michael's otherwise correct answer follows your false assumption.  You seem to understand the Estate Tax federal threshold. Jersey would have its own, and I have no idea how it works there. If the decedent happened to trade in the tax year prior to passing, normal tax rules apply.  Now, if the executor chooses to sell off and liquidate the estate to cash, there's no further taxable gain, a $5M portfolio can have millions in long term gain, but the step up basis pretty much negates all of it.  If that's the case, the beneficiaries aren't likely to repurchase those shares, in fact, they might not even know what the list of stocks was, unless they sifted through the asset list. But, that sale was unnecessary, assets can be divvied up and distributed in-kind, each beneficiary getting their fraction of the number of shares of each stock. And then your share of the $5M has a stepped up basis, meaning if you sell that day, your gains are near zero. You might owe a few dollars for whatever the share move in the time passing between the step up date and date you sell.  I hope that clarifies your misunderstanding.  By the way, the IRS is just an intermediary. It's congress that writes the laws, including the tangled web of tax code. The IRS is the moral equivalent of a great customer service team working for a company we don't care for. how is it double taxation when you didn't start off with that extra $100?  it's double taxation if they taxed you on the total amount you pulled out of the market, not the profit you made.   explain the math on your last part, please. "This question and your other one indicate you're a bit unclear on how capital gains taxes work, so here's the deal: you buy an asset (like shares of stock or a mutual fund).  You later sell it for more than you bought it for.  You pay taxes on your profit: the difference between what you sold it for and what you bought it for.  What matters is not the amount of money you ""withdraw"", but the prices at which assets are bought and sold. In fact, often you will be able to choose which individual shares you sell, which means you have some control over the tax you pay.  For a simple example, suppose you buy 10 shares of stock for $100 each in January (an investment of $1000); we'll call these the ""early"" shares.  The stock goes up to $200 in July, and you buy 10 more shares (investing an additional $2000); we'll call these the ""late"" shares.  Then the stock drops to $150.  Suppose you want $1500 in cash, so you are going to sell 10 shares. The 10 early shares you bought have increased in value, because you bought then for $100 but can now sell them for $150.  The 10 late shares have decreased in value, because you bought them for $200 but can now only sell them for $150.  If you choose to sell the early shares, you will have a capital gain of $500 ($1500 sale price minus $1000 purchase price), on which you may owe taxes.  If you sell the late shares, you will have a capital loss of $500 ($1500 sale price minus $2000 purchase price is -$500), which you can potentially use to reduce your taxes.  Or you could sell 5 of each and have no gain or loss (selling five early shares for $150 gives you a gain of $250, but selling five late shares for $150 gives you a loss of $250, and they cancel out). The point of all this is to say that the tax is not determined by the amount of cash you get, but by the difference between the sale price and the price you purchased for (known as the ""cost basis""), and this in turn depends on which specific assets you sell.  It is not enough to know the total amount you invested and the total gain.  You need to know the specific cost basis (i.e., original purchase price) of the specific shares you're selling.  (This is also the answer to your question about long-term versus short-term gains.  It doesn't matter how much money you make on the sale.  What matters is how long you hold the asset before selling it.) That said, many brokers will automatically sell your shares in a certain order unless you tell them otherwise (and some won't let you tell them otherwise).  Often they will use the ""first in, first out"" rule, which means they will always sell the earliest-purchased shares first. To finally get to your specific question about Betterment, they have a page here that says they use a different method.  Essentially, they try to sell your shares in a way that minimizes taxes.  They do this by first selling shares that have a loss, and only then selling shares that have a gain.  This basically means that if you want to cash out $X, and it is possible to do it in a way that incurs no tax liability, they will do that. What gets me very confused is if I continue to invest random amounts of money each month using Betterment, then I need to withdraw some cash, what are the tax implications.  As my long answer above should indicate, there is no simple answer to this.  The answer is ""it depends"".  It depends on exactly when you bought the shares, exactly how much you paid for them, exactly when and how much the price rose or fell, and exactly how much you sell them for.  Betterment is more or less saying ""Don't worry about any of this, trust us, we will handle everything so that your tax is minimized."" A final note: if you really do want to track the details of your cost basis, Betterment may not be for you, because it is an automated platform that may do a lot of individual trades that a human wouldn't do, and that can make tracking the cost basis yourself very difficult.  Almost the whole point of something like Betterment is that you are supposed to give them your money and forget about these details." "You cannot get ""your investment"" out and ""leave only the capital gains"" until they become taxable at the long-term rate. When you sell some shares after holding them for less than a year, you have capital gains on which you will have to pay taxes at the short-term capital gains rate (that is, at the same rate as ordinary income).  As an example, if you bought 100 shares at $70 for a net investment of $7000, and sell 70 of them at $100 after five months to get your ""initial investment back"", you will have short-term capital gains of $30 per share on the 70 shares that you sold and so you have to pay tax on that $30x70=$2100. The other $4900 = $7000-$2100 is ""tax-free"" since it is just your purchase price of the 70 shares being returned to you.  So after paying the tax on your short-term capital gains, you really don't have your  ""initial investment back""; you have something less. The capital gains on  the 30 shares that you continue to hold will become (long-term capital gains) income to you only when you sell the shares after having held them for a full year or more: the gains on the shares sold after five months are taxable income in the year of sale." "This answer is about the USA. Each time you sell a security (a stock or a bond) or some other asset, you are expected to pay tax on the net gain. It doesn't matter whether you use a broker or mutual fund to make the sale. You still owe the tax. Net capital gain is defined this way: Gross sale prices less (broker fees for selling + cost of buying the asset) The cost of buying the asset is called the ""basis price.""  You, or your broker, needs to keep track of the basis price for each share. This is easy when you're just getting started investing. It stays easy if you're careful about your record keeping.  You owe the capital gains tax whenever you sell an asset, whether or not you reinvest the proceeds in something else. If your capital gains are modest, you can pay all the taxes at the end of the year. If they are larger -- for example if they exceed your wage earnings -- you should pay quarterly estimated tax. The tax authorities ding you for a penalty if you wait to pay five- or six-figure tax bills without paying quarterly estimates.  You pay NET capital gains tax. If one asset loses money and another makes money, you pay on your gains minus your losses. If you have more losses than gains in a particular year, you can carry forward up to $3,000 (I think). You can't carry forward tens of thousands in capital losses.  Long term and short term gains are treated separately. IRS Schedule B has places to plug in all those numbers, and the tax programs (Turbo etc) do too. Dividend payments are also taxable when they are paid. Those aren't capital gains. They go on Schedule D along with interest payments. The same is true for a mutual fund. If the fund has Ford shares in it, and Ford pays $0.70 per share in March, that's a dividend payment. If the fund managers decide to sell Ford and buy Tesla in June,  the selling of Ford shares will be a cap-gains taxable event for you.  The good news: the mutual fund managers send you a statement sometime in February or March of each year telling what you should put on your tax forms.  This is great. They add it all up for you. They give you a nice consolidated tax statement covering everything: dividends, their buying and selling activity on your behalf, and any selling they did when you withdrew money from the fund for any purpose.   Some investment accounts like 401(k) accounts are tax free. You don't pay any tax on those accounts -- capital gains, dividends, interest -- until you withdraw the money to live on after you retire. Then that money is taxed as if it were wage income. If you want an easy and fairly reliable way to invest, and don't want to do a lot of tax-form scrambling, choose a couple of different mutual funds, put money into them, and leave it there. They'll send you consolidated tax statements once a year. Download them into your tax program and you're done. You mentioned ""riding out bad times in cash.""  No, no, NOT a good idea. That investment strategy almost guarantees you will sell when the market is going down and buy when it's going up. That's ""sell low, buy high."" It's a loser. Not even Warren Buffett can call the top of the market and the bottom.  Ned Johnson (Fidelity's founder) DEFINITELY can't." "I don't think its a taxable event since no income has been constructively received (talking about the RSU shareholders here). I believe you're right with the IRC 1033, and the basis of the RSU is the basis of the original stock option (probably zero). Edit: see below. However, once the stock becomes vested - then it is a taxable event (not when the cash is received, but when the chance of forfeiture diminishes, even if the employee doesn't sell the stock), and is an ordinary income, not capital. That is my understanding of the situation, do not consider it as a tax advice in any way. I gave it a bit more though and I don't think IRC 1033 is relevant. You're not doing any exchange or conversion here, because you didn't have anything to convert to begin with, and don't have anything after the ""conversion"". Your ISO's are forfeited and no longer available, basically - you treat them as you've never had them. What happened is that you've received RSU's, and you treat them as a regular RSU grant, based on its vesting schedule. The tax consequences are exactly as I described in my original response: you recognize ordinary income on the vested stocks, as they vest. Your basis is zero (i.e.: the whole FMV of the stock at the time of vesting is your ordinary income). It should also be reflected in your W2 accordingly." From 26 CFR 1.1012(c)(1)i): ... if a taxpayer sells or transfers shares of stock in a corporation that the taxpayer purchased or acquired on different dates or at different prices and the taxpayer does not adequately identify the lot from which the stock is sold or transferred, the stock sold or transferred is charged against the earliest lot the taxpayer purchased or acquired to determine the basis and holding period of the stock. From 26 CFR 1.1012(c)(3): (i) Where the stock is left in the custody of a broker or other agent, an adequate identification is made if—   (a) At the time of the sale or transfer, the taxpayer specifies to such broker or other agent having custody of the stock the particular stock to be sold or transferred, and ... So if you don't specify, the first share bought (for $100) is the one sold, and you have a capital gain of $800. But you can specify to the broker if you would rather sell the stock bought later (and thus have a lower gain). This can either be done for the individual sale (no later than the settlement date of the trade), or via standing order: 26 CFR 1.1012(c)(8) ... A standing order or instruction for the specific identification of stock is treated as an adequate identification made at the time of sale, transfer, delivery, or distribution. Any large stockbroker will offer trading in US securities. As a foreign national you will be required to register with the US tax authorities (IRS) by completing and filing a W-8BEN form and pay US withholding taxes on any dividend income you receive.  US dividends are paid net of withholding taxes, so you do not need to file a US tax return.  Capital gains are not subject to US taxes.  Also, each year you are holding US securities, you will receive a form from the IRS which you are required to complete and return. You will also be required to complete and file forms for each of the exchanges you wish to received market price data from. Trading will be restricted to US trading hours, which I believe is 6 hours ahead of Denmark for the New York markets.  You will simply submit an order to the desired market using your broker's online trading software or your broker's telephone dealing service. You can expect to pay significantly higher commissions for trading US securities when compared to domestic securities. You will also face potentially large foreign exchange fees when exchaning your funds from EUR to USD. All in all, you will probably be better off using your local market to trade US index or sector ETFs. This will work as intended, but there's another point to consider. In the US, the tax rate on proceeds from stock sales is higher for short term holdings, which are defined as held for less than one year. Both rates vary based on your income. Bracket numbers are for fiscal year 2014, filing as single. The difference between short and long term capital gains tax in the US is a minimum of ten percentage points, and works out to 15 percentage points on average. This is substantial. If you won't be reporting much income the year you move to the US (say because you only worked for a portion of the year) it is decidedly to your advantage to wait and sell the stocks in the US, to get that sweet 0% rate. At a minimum, you should hold the position for a year if you sell and rebuy, from a tax optimization perspective. Two caveats: A stock represents your share of ownership in a corporation. All of these shares indicate towards your part of ownership in a corporation a shareholder, stockholder or a shareowner in a company. In order to get a stock, be sure to secure the assistance of a licensed stockbroker to buy securities on your behalf. Yes, anyone having substantial amount of money to invest can buy/own/use stocks. Holding a stock for less than a year makes it a subject to tax on your regular income for short-term gains. Most of the people find it higher than the capital gains. In addition, your annual income also comes into play. Sale of a stock creates a capital gain. It can be offset with losses, up to $3000 more than the gains. It can be deferred when held within a retirement account.  When you gift appreciated stock, the basis follows. So when I gifted my daughter's trust shares, there was still tax due upon sale. The kiddy tax helped reduce but not eliminate it. And there was no quotes around ownership. The money is gone, her account is for college.  No 1031 exchange exists for stock. Restricted Stock Units are different from stock options because instead of buying them at a particular strike price, you receive the actual shares of stock. They are taxed as ordinary income at the time that the restriction is lifted (you don't have to sell them to be taxed). Usually, you can choose to have a percentage of the stock withheld to cover tax withholding or pay for the withholding out of pocket (so you can retain all of your shares).
