First of all, in the U.S., no Federal gift tax has to be paid by the recipient of  the gift; it is the donor who has to pay gift tax, if any is due. Nor does the recipient have to pay Federal income tax on the gift; it is not considered taxable income.  I do not believe that any states view matters differently for the purposes of state gift and income taxes, but I am always ready to be disabused of any such fondly-held notions. If your parents were required to pay any gift tax, that would have been at the  time the gift was originally given and only if they gifted more than the maximum allowable exemption per person for that year. Currently the exemption is $14K from each donor per recipient per year. Additional gifts were made by your parents to you during your minority when your parents paid any income tax  due on the distributions in your account, but these amounts would unlikely to have been larger than the exemption for that year. In any case, gift tax is  none of your concern. If you have been declaring the income from distributions from the mutual funds all these years, then the only tax due on the distributions from the funds in 2013 is the Federal income tax for the 2013 tax year (plus a special assessment of Medicare tax on investment income if your income is large; unlikely based on your question and follow-up comment).  If you sold all or part of your shares in the funds in 2013, then you would need to calculate the basis of your investments in the fund in order to figure out if you have capital gains or losses.  Ditto if you are thinking of cashing out in 2014 and wish to estimate how much income tax is due. But if you want to just hang on to the funds, then there is no immediate need to figure out the basis right away, though taking care of the matter and keeping in top of things for the future will be helpful. As a final note, there is no tax due on the appreciation of the fund's shares. The increased value of your account because the fund's share price rose is not a taxable event (nor are decreases in the account deductible). These are called unrealized capital gains (or losses) and you do not pay tax on them (or deduct them as losses) until you realize the gains by  disposing of the property. "Lending of shares happens in the background. Those who have lent them out are not aware that they have been lent out, nor when they are returned. The borrowers have to pay any dividends to the lenders and in the end the borrowers get their stock back. If you read the fine print on the account agreement for a margin account, you will see that you have given the brokerage the permission to silently loan your stocks out.  Since the lending has no financial impact on your portfolio, there's no particular reason to know and no particular protection required.  Actually, brokers typically don't bother going through the work of finding an actual stock to borrow.  As long as lots of their customers have stocks to lend and not that many people have sold short, they just assume there is no problem and keep track of how many are long and short without designating which stocks are borrowed from whom. When a stock becomes hard to borrow because of liquidity issues or because many people are shorting it, the brokerage will actually start locating individual shares to borrow, which is a more time-consuming and costly procedure.  Usually this involves the short seller actually talking to the broker on the phone rather than just clicking ""sell.""" "Why only long term investments? What do they care if I buy and sell   shares in a company in the same year? Simple, your actually investing when you hold it for a long term. If you hold a stock for a week or a month there is very little that can happen to change the price, in a perfect market the value of a company should stay the same from yesterday to today so long as there is no news(a perfect market cannot exist). When you hold a stock for a long term you really are investing in the company and saying ""this company will grow"". Short term investing is mostly speculation and speculation causes securities to be incorrectly valued. So when a retail investor puts money into something like Facebook for example they can easily be burned by speculation whether its to the upside or downside. If the goal is to get me to invest my money, then why not give apply   capital gains tax to my savings account at my local bank? Or a CD   account? I believe your gains on these accounts are taxed... Not sure at what rate. If the goal is to help the overall health of business, how does it do   that? During an IPO, the business certainly raises money, but after   that I'm just buying and selling shares with other private   shareholders. Why does the government give me an incentive to do this   (and then hold onto it for at least a year)? There are many reasons why a company cares about its market price: A companies market cap is calculated by price * shares outstanding. A market cap is basically what the market is saying your company is worth. A company can offer more shares or sell shares they currently hold in order to raise even more capital. A company can offer shares instead of cash when buying out another company. It can pay for many things with shares. Many executives and top level employees are payed with stock options, so they defiantly want to see there price higher. these are some basic reasons but there are more and they can be more complex." No. If you didn't specify LIFO on account or sell by specifying the shares you wish sold, then the brokers method applies.  From Publication 551 Identifying stock or bonds sold.   If you can adequately identify the   shares of stock or the bonds you sold, their basis is the cost or   other basis of the particular shares of stock or bonds. If you buy and   sell securities at various times in varying quantities and you cannot   adequately identify the shares you sell, the basis of the securities   you sell is the basis of the securities you acquired first. For more   information about identifying securities you sell, see Stocks and   Bonds under Basis of Investment Property in chapter 4 of Pub. 550. The trick is to identify the stock lot prior to sale. Is it just -34*4.58= -$155.72 for CCC and -11*0.41= -$4.51 for DDD? Yes it needs to be recorded as negative because at some point in time, the investor will have to spend money to buy these shares [cover the short sell and return the borrowed shares]. Whether the investor made profit or loss will not be reflected as you are only reflecting the current share inventory. I don't have a direct short position. It is a structured product linked to the performance of Tesla. I basically get a fixed coupon payment every quater and as long as Tesla doesn't move up more than 50% in the next half year I get my initial investment back plus the coupons. If it should move up more than 50% I lose that percentage of my initial investment I started investing in Robinhood, I'm 18 and just felt like it would be a good move. Bought 2 stocks of Nextera and 1 LIT. The stock prices both grew today, but very little as expected. But should I be concerned about the day to day growth of these stock or just leave them and let them sit for a couple months. From what I hear and know you sell when you're up and buy when it's down. "That share class may not have a ticker symbol though ""Black Rock MSCI ACWI ex-US Index"" does have a ticker for ""Investor A"" shares that is BDOAX.  Some funds will have multiple share classes that is a way to have fees be applied in various ways.  Mutual fund classes would be the SEC document about this if you want a government source within the US around this. Something else to consider is that if you are investing in a ""Fund of funds"" is that there can be two layers of expense ratios to consider.  Vanguard is well-known for keeping its expenses low."
