Filing taxes on stocks
Generally stock trades will require an additional Capital Gains and Losses form included with a 1040, known as Schedule D (summary) and Schedule D-1 (itemized).  That year I believe the maximum declarable Capital loss was $3000--the rest could carry over to future years. The purchase date/year only matters insofar as to rank the lot as short term or long term(a position held 365 days or longer), short term typically but depends on actual asset taxed then at 25%, long term 15%.  The year a position was closed(eg. sold) tells you which year's filing it belongs in. The tiny $16.08 interest earned probably goes into Schedule B, typically a short form. The IRS actually has a hotline 800-829-1040 (Individuals)  for quick questions such as advising which previous-year filing forms they'd expect from you.  Be sure to explain the custodial situation and that it all recently came to your awareness etc. Disclaimer: I am no specialist. You'd need to verify everything I wrote; it was just from personal experience with the IRS and taxes. You need to talk to an accountant who practices tax accounting, preferaby someone who is an Enrolled Agent (EA) with the IRS, and possibly an attorney who specializes in tax law.  There are multiple issues here, and the executor of your father's estate might need to be involved here too.  Presumably you were a minor in 2007 since the transactions took place in a custodial account, and perhaps you were a dependent of your father in 2007.  So, were the transactions reported on your father's 2007 income tax return? or did he file a separate income tax return in your name? You say you have a W2 for 2007. So you were  earning some income in 2007? This complicates matters. It is necessary to determine who has the responsibility to file income tax returns for a minor with earned income. Above all, I urge you to not file income tax returns on your own or using a tax return preparation program, or after talking to a tax return preparation service (where you will likely get someone who works on a seasonal basis and is unlikely to be familiar with tax law as of 2007). You need to submit an updated return. The problem is that once three years have passed you can't update the return to get any kind of refund, but if they are going after you for the sale price of the stocks, not knowing the cost, your goal is to show them there was no gain, and in fact you'd have had the loss if you were aware of the account. This is less than ten years back, so the broker should be able to give you the statements pretty easily.
You can always take deduction for foreign tax paid on Schedule A, or calculate foreign tax credit using form 1116. Credit is usually more beneficial, but in some cases you will be better of with a deduction. However, in very specific cases, you can claim the credit directly on your 1040 without using the form 1116. Look at the 1040 instructions for line 47: Exception.   You do not have to complete Form 1116 to take this credit   if all of the following apply. All of your foreign source gross income was from interest and dividends and all of that income and the foreign tax paid on it were   reported to you on Form 1099-INT, Form 1099-DIV, or Schedule K-1 (or   substitute statement). The total of your foreign taxes was not more than $300 (not more than $600 if married filing jointly). You held the stock or bonds on which the dividends or interest were paid for at least 16 days and were not obligated to pay these   amounts to someone else. You are not filing Form 4563 or excluding income from sources within Puerto Rico. All of your foreign taxes were: Legally owed and not eligible for a refund or reduced tax rate under a tax treaty, and Paid to countries that are recognized by the United States and do not support terrorism. For more details on these requirements, see the Instructions for   Form 1116. "I finally found it! Johnson Controls International PLC FORM 8-K/A (Amended Current report filing) Filed 10/03/16 for the Period Ending 09/02/16 from http://investors.johnsoncontrols.com/financial-information/johnson-sec-filings, says on page II-6: (my emphasis for the relevant paragraph) On September 2, 2016, Johnson Controls and Tyco completed their   combination pursuant to the Agreement and Plan of Merger (the “Merger   Agreement”), dated as of January 24, 2016, as amended by Amendment No.   1, dated as of July 1, 2016, by and among Johnson Controls, Tyco and   certain other parties named therein, including Jagara Merger Sub LLC, an   indirect wholly owned subsidiary of Tyco (“Merger Sub”).   Pursuant to the terms of the Merger Agreement, on September 2, 2016,   Merger Sub merged with and into Johnson Controls with Johnson Controls   being the surviving corporation in the merger and a wholly owned,   indirect subsidiary of Tyco (the “merger”).   Following the merger, Tyco changed its name to “Johnson Controls   International plc.”  Immediately prior to the merger and in connection   therewith, Tyco shareholders received 0.955 ordinary shares of Tyco   (which shares are now referred to as “combined company ordinary shares”)   for each Tyco ordinary share they held by virtue of a 0.955-for-one   share consolidation. In the merger, each outstanding share of common   stock, par value $1.00 per share, of Johnson Controls (“Johnson Controls   common stock”) (other than shares held by Johnson Controls, Tyco and   certain of their subsidiaries) was converted into the right to receive   either the cash consideration or the share consideration (each as   described below), at the election of the holder, subject to proration   procedures described in the Merger Agreement and applicable withholding   taxes.   The election to receive the cash consideration was undersubscribed. As a   result, holders of shares of Johnson Controls common stock that elected   to receive the share consideration and holders of shares of Johnson   Controls common stock that made no election (or failed to properly make   an election) became entitled to receive, for each such share of Johnson   Controls common stock, $5.7293 in cash, without interest, and 0.8357   combined company ordinary shares, subject to applicable withholding   taxes.   Holders of shares of Johnson Controls common stock that elected to   receive the cash consideration became entitled to receive, for each such   share of Johnson Controls common stock, $34.88 in cash, without   interest, subject to applicable withholding taxes.   In the merger, Johnson Controls shareholders received, in the aggregate,   approximately $3.864 billion in cash. Immediately after the closing of,   and giving effect to, the merger, former Johnson Controls shareholders   owned approximately 56% of the issued and outstanding combined company   ordinary shares and former Tyco stockholders owned approximately 44% of   the issued and outstanding combined company ordinary shares. This answers what actually happened in the transaction; as far as my cost basis in the new JCI, it's a little more obscure; on page II-7 it says: For pro forma purposes, the valuation of consideration transferred is   based on, amongst other things, the adjusted share price of Johnson   Controls on September 2, 2016 of $47.67 per share and on page II-8: Johnson Controls adjusted share price as of September 2, 2016 (2): $47.67 (2) Amount equals Johnson Control closing share price and market   capitalization at September 2, 2016 ($45.45 and $29,012 million,   respectively) adjusted for the Tyco $3,864 million cash contribution   used to purchase 110.8 million shares of Johnson Controls stock for   $34.88 per share. and both agree with the information posted at http://www.secinfo.com/dpdtb.w6n.2n.htm#1stPage (R66 Merger Transaction Fair Value of Consideration Transferred (Details)) which I can't seem to find on an ""official"" website but it purports to post from the SEC EDGAR database.    So for each share of JCI, it had a fair value of $47.67 prior to the acquisition, and transformed into $5.7293 in cash, plus 0.8357 of ""new"" JCI shares with a basis of $47.67 - $5.7293 = $41.9407. Stated in terms of ""new"" JCI shares, this is $50.1863 (=$41.9407/0.8357) per ""new"" JCI share. (I'm not really 100% sure of this calculation though.)  I also found JCI's Form 8937 which states Fair market value generally is the price at which property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell and both having reasonable knowledge of the facts. U.S. federal income tax law does not specifically prescribe how former JCI shareholders should determine the fair market value of the Tyco ordinary shares received in the merger.  One possible method of determining the fair market value of one Tyco ordinary share is to use the average of the high and low trading prices on the date of the merger, which was $45.69. Other methods for determining the fair market value of Tyco ordinary shares are possible. Former JCI shareholders are not bound by the approach described above and may, in consultation with their tax advisors, use another approach.   as well as similar text on the IRS website: One possible method of determining the fair market value of one Tyco ordinary share is to use the average of the high and low trading prices on the date of the merger, which was $45.69. Using this figure, former JCI shareholders that elected to receive shares in the merger would receive cash and Tyco ordinary shares worth approximately $43.91 per share of JCI common stock exchanged in the merger (assuming no cash received in lieu of fractional shares)." "No, there are no issues.  When you form the corp in DE, you pick a business there to serve as your ""agent"" (essentially someone who knows to get in contact with you).  The ""agent"" will notify you about taxes and any mail you get, but besides the fee they charge you for being the agent, you should file all the taxes directly with DE (franchise tax is easy to file on the web) instead of going through the agent and paying a surcharge. When your LLC files taxes, you'll do so in DE and then the LLC will issue you a federal and state K1.  You'll file taxes where you reside and use the federal K1, but I think you might have to file DE state taxes (unsure about this part, feel free to edit or comment and I'll correct)." Here're some findings upon researches: Two main things to watch out for: Estate tax and the 30% tax withholding. These 2 could be get around by investing in Luxembourg or Ireland  domiciled ETF. For instance there's no tax withholding on Ireland domiciled ETF dividend, and the estate tax is not as high. (source: BogleHead forums)  Some Vanguard ETF offered in UK stock market: https://www.vanguard.co.uk/uk/mvc/investments/etf#docstab. Do note that the returns of S&P 500 ETF (VUSA) are adjusted after the 30% tax withholding! Due to VUSA's higher TER (0.09%), VOO should remain a superior choice. The FTSE Emerging Markets and All-World ETFs though, are better than their US-counterparts, for non-US residents. Non-US residents are able to claim back partials of the withhold tax, by filing the US tax form 1040NR. In 2013, non-US resident can claim back at least $3,900. Kindly correct me if anything is inaccurate. "An investment is sold when you sell that particular stock or fund. It doesn't wait until you withdraw cash from the brokerage account. Whether an investment is subject to long term or short term taxes depends on how long you held that particular stock. Sorry, you can't get around the higher short term tax by leaving the money in a brokerage account or re-investing in something else. If you are invested in a mutual fund, whether it's long or short term depends on when you buy and sell the fund. The fact that the fund managers are buying and selling behind your back doesn't affect this. (I don't know what taxes they have to pay, maybe you really are paying for it in the form of management fees or lower returns, but you don't explicitly pay the tax on these ""inner"" transactions.) Your broker should send you a tax statement every year giving the numbers that you need to fill in to the various boxes of your income tax form. You don't have to figure it out. Of course it helps to know the rules. If you've held a stock for 11 1/2 months and are planning to sell, you might want to consider waiting a couple of weeks so it becomes a long term capital gain rather than short term and thus subject to lower tax." 10-Q is the quarterly report, and accordingly is filed quarterly. Similarly, 10-K is the annual report. 8-K is a general form for notification of material events. It is filed every time a material event is required to be reported to the shareholders. It may accompany the periodical reports, but doesn't have to. It can be filed on its own. If you're only interested in the financial statements, then you should be looking for the 10K/10Q forms. SEC will tell you when the forms were filed (dates), but it won't tell you what's more material and what's less. So you can plot a stock price graph on these dates, and see what was deemed more material by the investors based on the price fluctuations, but be prepared to find fluctuations that have no correlation to filings - because the market as a whole can drag the stock up or down. Also, some events may not be required to be reported to SEC, but may be deemed material by the investors. For example, a Cupertino town hall meeting discussing the zoning for the new AAPL HQ building may be deemed material by the investors, based on the sentiments, even if no decision was made to be reported to SEC. You realise a capital gain as soon as you sell the stock. At that point, you will have to pay taxes on the profits when you fill in your tax return. The fact that you used the money to subsequently purchase other stocks is not relevant, unless you sell those stocks within the same tax year. For example, purchase $5000 of stock A in 2010. Sell for $6000 in 2010. Purchase $6000 of stock B in 2010. Sell stock B for $6500 in 2010. Purchase $6500 of stock C in 2010. Sell stock C for $7000 in 2011. You owe capital gains on ($6000 - $5000) + ($6500 - $6000) = $1500 for tax year 2010. You owe capital gains on ($7000 - $6500) = $500 for 2011. "There are many people who have deductions far above the standard deduction, but still don't itemize. That's their option even though it comes at a cost. It may be foolish, but it's not illegal.  If @littleadv citation is correct, the 'under penalty of perjury' type issue, what of those filers who file a Schedule A but purposely leave off their donations? I've seen many people discuss charity, and write that they do not want to benefit in any way from their donation, yet, still Schedule A their mortgage and property tax. Their returns are therefore fraudulent.  I am curious to find a situation in which the taxpayer benefits from such a purposeful oversight, or, better still, a cited case where they were charged with doing so. I've offered advice on filings return that wasn't ""truthful"". When you own a stock and cannot find cost basis, there are times that you might realize the basis is so low that just entering zero will cost you less than $100 in extra tax. You are not truthful, of course, but this kind of false statement isn't going to lead to any issue. If it gets noticed within an audit, no agent is going to give it more than a moment of time and perhaps suggest, ""you didn't even know the year it was bought?"" but there would be no consequence.  My answer is for personal returns, I'm sure for business, accuracy to the dollar is actually important."
