Paying Tax on Stocks Trading
The answer to your question doesn't depend on who you trade with but what country you live in. If you live outside of the US, you will have to pay tax on dividends... sometimes. This depends on the tax treaty that your country has with the US. Canada, Australia, UK and a few other countries have favorable tax treaties with the US that allow you to not be double taxed. You must look into the tax treaty that your home country has with the US to answer the question. Each country is different.
No, you can not cheat the IRS. This question is also based on the assumption that the stock will return to $1 which isn't always a safe assumption and that it will continue to cycle like that repeatedly which is also likely a false assumption. "You have a sequence of questions here, so a sequence of answers: If you stopped at the point where you had multiple wins with a net profit of $72, then you would pay regular income tax on that $72. It's a short term capital gain, which does not get special tax treatment, and the fact that you made it on multiple transactions does not matter. When you enter your next transaction that takes the hypothetical loss the question gets more complicated. In either case, you are paying a percentage on net gains.  If you took a two year view in the second case and you don't have anything to offset your loss in the second year, then I guess you could say that you paid more tax than you won in the total sequence of trades over the two years. Although you picked a sequence of trades where it does not appear to play, if you're going to pursue this type of strategy then you are likely at some point to run into a case where the ""wash sale"" rules apply, so you should be aware of that.  You can find information on this elsewhere on this site and also, for example, here: http://www.marketwatch.com/story/understanding-the-wash-sale-rules-2015-03-02  Basically these rules require you to defer recording a loss under some circumstances where you have rapid wins and losses on ""substantially identical"" securities. EDIT A slight correction, you can take part of your losses in the second year even if you have no off-setting gain.  From the IRS: If your capital losses exceed your capital gains, the amount of the excess loss that you can claim on line 13 of Form 1040 to lower your income is the lesser of $3,000, ($1,500 if you are married filing separately)" 83(b) election requires you to pay the current taxes on the discount value. If the discount value is 0 - the taxes are also 0. Question arises - why would someone pay FMV for restricted stocks? That doesn't make sense. I would argue, as a devil's advocate, that the FMV is not really fair market value, since the restriction must have reduced the price you were willing to pay for the stocks. Otherwise why would you buy the stocks at full price - with strings attached that could easily cost you the whole amount you paid? 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 depends on the particular index, of course. Capital gains taxes occur when stock is sold (for a profit). This occurs less frequently in an index fund: Where an active manager frequently buys and sells stocks (after all, he wants to be active :-) ), the index fund only sells stocks when the particular stock leaves the index. For an index such as the S&P 500 this does not happen that often.  The more specific the criteria of the index fund, the more often the selling of stock and thus the need to pay capital gains taxes occurs. "There are two ways to handle this. The first is that the better brokers, such as Charles Schwab, will produce summaries of your gains and losses (using historical cost information), as well as your trades, on a monthly and annual basis. These summaries are ""ready made"" for the IRS. More brokers will provide these summaries come 2011. The second is that if you are a ""frequent trader"" (see IRS rulings for what constitutes one), then they'll allow you to use the net worth method of accounting. That is, you take the account balance at the end of the year, subtract the beginning balance, adjust the value up for withdrawals and down for infusions, and the summary is your gain or loss. A third way is to do all your trading in say, an IRA, which is taxed on distribution, not on stock sales." Normally, you don't pay capital gains tax until you actually realize a capital gain.  However, there are some exceptions. The exception that affected Eduardo Saverin is the expatriation tax, or exit tax.  If you leave a country and are no longer a tax resident, your former country taxes you on your unrealized capital gains from the period that you were a tax resident of that country.  There are several countries that have an expatriation tax, including the United States.  Saverin left the U.S. before the Facebook IPO. Saverin was perhaps already planning on leaving the U.S. (he is originally from Brazil and has investments in Asia), so leaving before the IPO limited the amount of capital gains tax he had to pay upon his exit.  (Source: Wall Street Journal: So How Much Did He Really Save?) Another situation that might be considered an exception and affects a lot of us is capital gain distributions inside a mutual fund.  When mutual fund managers sell investments inside the fund and realize gains, they have to distribute those gains among all the mutual fund investors.  This often takes the form of additional shares of the mutual fund that you are given, and you have to pay capital gains tax on these distributions.  As a result, you can invest in a mutual fund, leave your money there and not sell, but have to pay capital gains tax anyway.  In fact, you could owe capital gains tax on the distributions even if the value of your mutual fund investment has gone down. I don't see a tag for United States, so I'm having to assume this is US taxes.  It doesn't matter what app you use, IRS trades are all calculated the same. First, you have to report each trade on a 8949 and from that the totals go into a schedule D.  Short term trades are stocks that you've kept exactly one year or less, long term trades are for 1 year + 1 day or more.  Trades where you sold a stock for a loss, then bought that stock back again under 30 days don't get to count as a loss.  This only affects realized capital gains and losses, you don't count fees. First, take all of your short term gains then offset them by all of your short term losses.  Do the same for long term gains and losses.  Short and long term gains are taxed at different rates.  You can deduct losses from short term to your long term and vice versa.  Then you can deduct the total losses up to $3000 (household, $1500 married, filing separately) per year on your regular income taxes or other dividend taxes.  If you have over $3000 in losses, then you need to carry that over to subsequent years. Edited per Dave's comments: thanks Dave Capital gains taxes for a year are calculated on sales of assets that take place during that year.  So if you sell some stock in 2016, you will report those gains/losses on your 2016 tax return. Does my prior answer here to a slightly different question help at all? Are there capital gains taxes or dividend taxes if I invest in the U.S. stock market from outside of the country? If the brokerage account holds US assets, such as the stock of US companies, then it may be taxable under some conditions. The rules are complex and depend on the nationality of the individuals, because the results may be affected by tax treaties between the United States and whatever country the person is from. A purchase of a stock is not a taxable event. No 1099 to worry about.  Welcome to Money.SE "While @JB's ""yes"" is correct, a few more points to consider: There is no tax penalty for withdrawing any time from a taxable investment, that is, one not using specific tax protections like 401k/IRA or ESA or HSA. But you do pay tax on any income or gain distributions you receive from a taxable investment in a fund (except interest on tax-exempt aka ""municipal"" bonds),  and any net capital gains you realize when selling (or technically redeeming for non-ETF funds). Just like you do for dividends and interest and gains on non-fund taxable investments. Many funds have a sales charge or ""load"" which means you will very likely lose money if you sell quickly typically within at least several months and usually a year or more, and even some no-load funds, to discourage rapid trading that makes their management more difficult (and costly), have a ""contingent sales charge"" if you sell after less than a stated period like 3 months or 6 months.  For funds that largely or entirely invest in equities or longer term bonds, the share value/price is practically certain to fluctuate up and down, and if you sell during a ""down"" period you will lose money; if ""liquid"" means you want to take out money anytime without waiting for the market to move, you might want funds focussing on short-term bonds, especially government bonds, and ""money market"" funds which hold only very short bonds (usually duration under 90 days), which have much more stable prices (but lower returns over the longer term)." "Except for one thing, right now there is a large amount of speculation, lots of numbers are inflated. And then we have the high frequency traders, this tax would make it harder to make money on nothing, which is what they are doing currently. Personally I would be fine with it if the tax became ""exempt"" after say holding the stock for 3-6-12 months. This tax also isn't about making money, its about making the market more secure. One of the downsides is that if all the major markets don't commit to it, it likely will hurt anyone that does." "Aside from the fact that everyone - absolutely everyone, from the level of the individual to the government as a whole - treats ""free"" money frivolously, wastes it, misappropriates it, etc...  I do see one benefit to something like this.   The whole idea of the stock market isn't millisecond trading to game the casino that is Wall Street.  Optimistically, you purchase stocks as a long-term investment in companies to enable their continued growth and stability, they make profits, they pass along these profits to you, and everyone benefits.  Suppressing this sort of roulette wheel speculation, constant changing of hands, fractional gains and the like seems like it would stabilize markets, improve growth, stop the damn CEO's and their golden parachute tactics in killing companies, and all that jazz.  Joe Shmoe isn't going to care about a tax like this - he buys into whatever he wants and usually hangs on to it for the long term.  I'm a layman, and admittedly a damned rusty one at economics, so give me a little slack if I'm wrong or just misguided altogether."
