How will my stock purchase affect my taxes?
Assuming you are in the US, and are an average joe, the answer to your question is no. Investment costs do not reduce your taxable income for the year you make the investment. They do factor in to the cost basis of your investment and so will affect your taxes in the year you sell the investment. If you want to reduce your taxable income, you could contribute the $5000 to a traditional ira, or 401k, assuming you qualify. Depending on where the account is held, you may then be able to use that $5k to purchase stock in the company you are interested in. The stock would be held in your IRA or 401k account, and would be subject to more restrictions than a normal brokerage account. Purchasing stock doesn't affect your immediate taxes any more than purchasing anything else, unless you purchase it through a traditional 401k or some other pre-tax vehicle. Selling stock has tax effects; that's when you have a gain or loss to report.
"Long term: Assuming you sold stock ABC through a registered stock exchange, e.g., the Bombay Stock Exchange or the National Stock Exchange of India, and you paid the Securities Transaction Tax (STT), you don't owe any other taxes on the long term capital gain of INR 100. If you buy stock BCD afterwards, this doesn't affect the long term capital gains from the sale of stock ABC.  Short term: If you sell the BCD stock (or the ABC stock, or some combination therein) within one year of its purchase, you're required to pay short term capital gains on the net profit, in which case you pay the STT and the exchange fees and an additional flat rate of 15%.  The Income Tax Department of India has a publication titled ""How to Compute your Capital Gains,"" which goes into more detail about a variety of relevant situations." No, you're not missing anything. RSUs are pretty simple when it comes to taxes. They are taxed as compensation at fair market value when they vest, basically equivalent to the company giving you a cash bonus and then using it to buy company stock. The fair market value at vesting then becomes your cost basis. Assuming the value has increased since vesting, selling the shares that vested at least a year ago (to qualify for lower long-term capital gains tax rates) with the highest cost basis with result in the minimum taxes. You only got 75 shares, so your basis is the fair market value of the stock as of the grant date times the number of shares you got: $20*75.  Functionally, it's the same thing as if your employer did this: As such, the basis in that stock is $1,500 ($20*75). The other 25 shares aren't yours and weren't ever yours, so they aren't part of your basis (for net issuance; if they were sell to cover, then the end result would be pretty similar, but there'd be another transaction involved, but we won't go there).  To put it another way, suppose your employer paid you a $2000 bonus, leaving you with a $1500 check after tax withholding. Being a prudent person and not wishing to blow your bonus on luxury goods, you invest that $1500 in a well-researched investment. You wouldn't doubt that your cost basis in that investment at $1500. It's not all roses, as I understand it, one effect of a tax inversion move is that existing stockholders will get hit with capital gains tax on the stock they hold as part of the conversion process.  Edit: going a bit further, often officers of the corporation are insulated from this tax as they have agreements that the company will pay their tax in the event of such a conversion. Seems like a potential for conflict of interest of officers vs shareholders to me.  It's unknown if this is the case with BK execs. ESPP tax treatment is complicated.  If you received a discount on the purchase of your stock, that discount is taxable as ordinary income when you sell the stock.  Any profit about the market value when the stock was purchased is taxed based upon the holding period of the stock. If you have held the stock less than a year, the profit is taxed at your marginal tax rate (ie taxed as ordinary income). If the stock is held for more than a year, it is taxed at a special capital gains tax rate, which ranges from 0-20% depending on your marginal tax rate (most people pay 15%). 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. Note that you're asking about withholding, not about taxing.  Withholding doesn't mean this is exactly the tax you'll pay: it means they're withholding a certain amount to make sure you pay taxes on it, but the tax bill at the end of the year is the same regardless of how you choose to do the withholding.  Your tax bill may be higher or lower than the withholding amount. As far as tax rate, that will be the same regardless - you're just moving the money from one place to the other.   The only difference would be that your tax is based on total shares under the plan - meaning that if you buy 1k shares, for example, at $10, so $1,500 discounted income, if you go the payroll route you get (say) $375 withheld.  If you go the share route, you either get $375 worth of stock (so 38 shares) withheld (and then you would lose out on selling that stock, meaning you don't get quite as much out of it at the end) or you would ask them to actually buy rather more shares to make up for it, meaning you'd have a slightly higher total gain.  That would involve a slightly higher tax at the end of it, of course. Option 1:  Buy and then sell $10000 worth, share-based withholding.  Assuming 15% profit, and $10/share at both points, then buy/sell 1000 shares, $1500 in profit to take into account, 38 shares' worth (=$380) withheld.  You put in $8500, you get back $9620, net $1120.   Option 2:  Buy and then sell $13500 worth, share based withholding.  Same assumptions.  You make about $2000 in pre-tax profit, meaning you owe about $500 in tax withholding.  Put in $11475, get back $13000, net $1525.  Owe 35% more tax at the end of the year, but you have the full $1500 to spend on whatever you are doing with it. Option 3:  Buy and then sell $1000 worth, paycheck withholding.  You get the full $10000-$8500 = $1500 up front, but your next paycheck is $375 lighter.  Same taxes as Option 1 at the end of the year. Assuming US. The only con that I know of is that hassle factor. You have to remember to sell when you get the new shares, and your taxes become a bit more complicated; the discount that you receive is taxed as ordinary income, and then any change in the price of the stock between when you receive it and you sell it will be considered a capital gain or loss. It's not hard to account for properly if you keep good records. It was not 100% clear if you have held all of these stocks for over a year.  Therefore, depending on your income tax bracket, it might make sense to hold on to the stock until you have held the individual stock for a year to only be taxed at long-term capital gains rates.  Also, you need to take into account the Net Investment Income Tax(NIIT), if your current modified adjusted income is above the current threshold.  Beyond these, I would think that you would want to apply the same methodology that caused you to buy these in the first place, as it seems to be working well for you. 2 & 3. No.  You trigger a taxable event and therefore have to pay capital gains tax on any gains.  If you have a loss in the stock and repurchase the stock within 30 days, you don't get to recognize the loss and have to add the loss to your basis in the stock (Wash Sales Rules). The original post's $16 has two errors: Here is the first scenario: .                                                 Tax Liability($) on   Net .

Yes, this is 25% of $172 - $100. "In the USA there are two ways this situation can be treated. First, if your short position was held less than 45 days. You have to (when preparing the taxes) add the amount of dividend back to the purchase price of the stock. That's called adjusting the basis. Example: short at $10, covered at $8, but during this time stock paid a $1 dividend. It is beneficial for you to add that $1 back to $8 so your stock purchase basis is $9 and your profit is also $1. Inside software (depending what you use) there are options to click on ""adjust the basis"" or if not, than do it manually specifically for those shares and add a note for tax reviewer. Second option is to have that ""dividednd payment in lieu paid"" deducted as investment expence. But that option is only available if you hold the shorts for more than 45 days and itemize your deductions. Hope that helps!" You wouldn't fill out a 1099, your employer would or possibly whoever manages the stock account.   The 1099-B imported from E-Trade says I had a transaction with sell price ~$4,500.   Yes.  You sold ~$4500 of stock to pay income taxes.  Both the cost basis and the sale price would probably be ~$4500, so no capital gain.  This is because you received and sold the stock at the same time.  If they waited a little, you could have had a small gain or loss.   The remainder of the stock has a cost basis of ~$5500.   There are at least two transactions here.   In the future you may sell the remaining stock.  It has a cost basis of ~$5500.  Sale price of course unknown until then.  You may break that into different pieces.  So you might sell $500 of cost basis for $1000 with a ~$500 capital gain.  Then later sell the remainder for $15,000 for a capital gain of ~$10,000. You normally only pay taxes on the difference between the sale price and the cost basis of the asset. In your example, you would probably pay taxes on the $10 difference, not the full sale price of $110. If you paid a commission, however, you would be taxed on your gain minus the commission you paid. Since you held the asset for less than a year, you wouldn't pay the long-term capital gains rate of 20%; you'd be taxed on the capital gain as if it were ordinary income, which depends on your federal income tax bracket. Also, littleadv makes a good point about the implications of buying the asset with after-tax funds too, so that's another part of the equation to consider as well. "This stock is the same as any other, but you need to keep clear in your head that you and your company are now different entities.  You (the person) will pay tax on capital gains and losses when you sell any stock that you hold in your own name.  You'll also owe ""regular"" tax if you draw a salary, etc.  The fact that it may be ""your"" company does not change these things. The company will not recognize a gain by selling stock to raise capital since it's nominally exchanging things of equal value, say $100 in cash for $100 in stock.  In order to sell stock, however, you MIGHT need to register with the SEC depending on how you're going about finding your investors, so keep that in mind." I gift my daughter stock worth $1000. No tax issue. She sells it for $2000, and has a taxable gain of $1000 that shows up on her return.  Yes, you need to find out the date of the gift, as that is the date you value the fund for cost basis. The $3500 isn't a concern, as the gift seems to have been given well before that. It's a long term capital gain when you sell it.  And, in a delightfully annoying aspect of our code, the dividends get added to basis each year, as you were paying tax on the dividend whether or not you actually received it. Depending on the level of dividends, your basis may very well be as high as the $6500 current value.  (pls ask if anything here needs clarification)
