134. Tax rules for United States citizens living in the US but being paid from outside the US
You can and are supposed to report self-employment income on Schedule C (or C-EZ if eligible, which a programmer likely is) even when the payer isn't required to give you 1099-MISC (or 1099-K for a payment network now). From there, after deducting permitted expenses, it flows to 1040 (for income tax) and Schedule SE (for self-employment tax). See https://www.irs.gov/individuals/self-employed for some basics and lots of useful links. If this income is large enough your tax on it will be more than $1000, you may need to make quarterly estimated payments (OR if you also have a 'day job' have that employer increase your withholding) to avoid an underpayment penalty. But if this is the first year you have significant self-employment income (or other taxable but unwithheld income like realized capital gains) and your economic/tax situation is otherwise unchanged -- i.e. you have the same (or more) payroll income with the same (or more) withholding -- then there is a 'safe harbor': if your withholding plus estimated payments this year is too low to pay this year's tax but it is enough to pay last year's tax you escape the penalty. (You still need to pay the tax due, of course, so keep the funds available for that.) At the end of the first year when you prepare your return you will see how the numbers work out and can more easily do a good estimate for the following year(s). A single-member LLC or 'S' corp is usually disregarded for tax purposes, although you can elect otherwise, while a (traditional) 'C' corp is more complicated and AIUI out-of-scope for this Stack; see https://www.irs.gov/businesses/small-businesses-self-employed/business-structures for more.

135. What are my investment options in real estate?
I compared investing in real estate a few years ago to investing in stocks that paid double digit dividends (hard to find, however, managing and maintaining real estate is just as hard).  After discussing with many in the real estate world, I counted the average and learned that most averaged about 6 - 8% on real estate after taxes.  This does not include anything else like Dilip mentions (maintenance, insurance, etc).  For those who want to avoid that route, you can buy some companies that invest in real estate or REIT funds like Dilip mentions.  However, they are also susceptible to the problems mentioned above this. In terms of other investment opportunities like stocks or funds, think about businesses that will always be around and will always be needed.  We won't outgrow our need for real estate, but we won't outgrow our need for food or tangible goods either.  You can diversify into these companies along with real estate or buy a general mutual fund. Finally, one of your best investments is your career field - software.  Do some extra work on the side and see if you can get an adviser position at a start-up (it's actually not that hard and it will help you build your skill set) or create a site which generates passive revenue (again, not that hard).  One software engineer told me a few years ago that the stock market is a relic of the past and the new passive income would be generated by businesses that had tools which did all the work through automation (think of a smart phone application that you build once, yet continues to generate revenue).  This was right before the crash, and after it, everyone talked about another "lost decade."  While it does require extra work initially, like all things software related, you'll be discovering tools in programming that you can use again and again in other applications - meaning your first one may be the most difficult. All it takes in this case is one really good idea ...

136. Does the Black-Scholes Model apply to American Style options?
A minor tangent. One can claim the S&P has a mean return of say 10%, and standard deviation of say 14% or so, but when you run with that, you find that the actual returns aren't such a great fit to the standard bell curve. Market anomalies producing the "100-year flood" far more often than predicted over even a 20 year period. This just means that the model doesn't reflect reality at the tails, even if the +/- 2 standard deviations look pretty. This goes for the Black-Sholes (I almost abbreviated it to initials, then thought better, I actually like the model) as well. The distinction between American and European is small enough that the precision of the model is wider than the difference of these two option styles. I believe if you look at the model and actual pricing, you can determine the volatility of a given stock by using prices around the strike price, but when you then model the well out of money options, you often find the market creating its own valuation.

137. Is there anything I can do to prepare myself for the tax consequences of selling investments to buy a house?
If you need less than $125k for the downpayment, I recommend you convert your mutual fund shares to their ETF counterparts tax-free: Can I convert conventional Vanguard mutual fund shares to Vanguard   ETFs? Shareholders of Vanguard stock index funds that offer Vanguard ETFs   may convert their conventional shares to Vanguard ETFs of the same   fund. This conversion is generally tax-free, although some brokerage   firms may be unable to convert fractional shares, which could result   in a modest taxable gain. (Four of our bond ETFs—Total Bond Market,   Short-Term Bond, Intermediate-Term Bond, and Long-Term Bond—do not   allow the conversion of bond index fund shares to bond ETF shares of   the same fund; the other eight Vanguard bond ETFs allow conversions.) There is no fee for Vanguard Brokerage clients to convert conventional   shares to Vanguard ETFs of the same fund. Other brokerage providers   may charge a fee for this service. For more information, contact your   brokerage firm, or call 866-499-8473. Once you convert from conventional shares to Vanguard ETFs, you cannot   convert back to conventional shares. Also, conventional shares held   through a 401(k) account cannot be converted to Vanguard ETFs. https://personal.vanguard.com/us/content/Funds/FundsVIPERWhatAreVIPERSharesJSP.jsp Withdraw the money you need as a margin loan, buy the house, get a second mortgage of $125k, take the proceeds from the second mortgage and pay back the margin loan. Even if you have short term credit funds, it'd still be wiser to lever up the house completely as long as you're not overpaying or in a bubble area, considering your ample personal investments and the combined rate of return of the house and the funds exceeding the mortgage interest rate.  Also, mortgage interest is tax deductible while margin interest isn't, pushing the net return even higher. $125k Generally, I recommend this figure to you because the biggest S&P collapse since the recession took off about 50% from the top.  If you borrow $125k on margin, and the total value of the funds drop 50%, you shouldn't suffer margin calls. I assumed that you were more or less invested in the S&P on average (as most modern "asset allocations" basically recommend a back-door S&P as a mix of credit assets, managed futures, and small caps average the S&P). Second mortgage Yes, you will have two loans that you're paying interest on. You've traded having less invested in securities & a capital gains tax bill for more liabilities, interest payments, interest deductions, more invested in securities, a higher combined rate of return. If you have $500k set aside in securities and want $500k in real estate, this is more than safe for you as you will most likely have a combined rate of return of ~5% on $500k with interest on $500k at ~3.5%.  If you're in small cap value, you'll probably be grossing ~15% on $500k. You definitely need to secure your labor income with supplementary insurance.  Start a new question if you need a model for that. Secure real estate with securities A local bank would be more likely to do this than a major one, but if you secure the house with the investment account with special provisions like giving them copies of your monthly statements, etc, you might even get a lower rate on your mortgage considering how over-secured the loan would be. You might even be able to wrap it up without a down payment in one loan if it's still legal.  Mortgage regulations have changed a lot since the housing crash.

138. Question about being a resident
This sort of involves personal finance, and sort of not. But it's an interesting question, so let's call it on topic? Short answer: yes. Long answer: it depends who's asking. If you're trying to qualify for in-state tuition, for example, you need to have been in state for a certain amount of time. For tax purposes, the first year you move to a new state you need to file part-time resident returns in your previous and current state of residency

139. Weekly budgets based on (a variable) monthly budget
If you know, approximately, the minimum he would get in a month, his budget should be planned based on this amount. In months where he gets more than this, the excess should be put aside. In really bad months where the income drops below the expected minimum, he can use the money put aside. After a year of putting money aside, he can plan to use and budget this for any other expenses.

140. How do annual risks translate into long-term risks?
The short answer is the annualised volatility over twenty years should be pretty much the same as the annualised volatility over five years. For independent, identically distributed returns the volatility scales proportionally. So for any number of monthly returns T, setting the annualization factor m = 12 annualises the volatility.  It should be the same for all time scales.  However, note the discussion here: https://quant.stackexchange.com/a/7496/7178 Scaling volatility [like this] only is mathematically correct when the   underlying price model is driven by Geometric Brownian motion which   implies that prices are log normally distributed and returns are   normally distributed. Particularly the comment: "its a well known fact that volatility is overestimated when scaled over long periods of time without a change of model to estimate such "long-term" volatility." Now, a demonstration.  I have modelled 12,000 monthly returns with mean = 3% and standard deviation = 2, so the annualised volatility should be Sqrt(12) * 2 = 6.9282.   Calculating annualised volatility for return sequences of various lengths (3, 6, 12, 60 months etc.) reveals an inaccuracy for shorter sequences.  The five-year sequence average got closest to the theoretically expected figure (6.9282), and, as the commenter noted "volatility is [slightly] overestimated when scaled over long periods of time". Annualised volatility for varying return sequence lengths  Edit re. comment Reinvesting returns does not affect the volatility much.  For instance, comparing some data I have handy, the Dow Jones Industrial Average Capital Returns (CR) versus Net Returns (NR).  The return differences are somewhat smoothed, 0.1% each month, 0.25% every third month.  More erratic dividend reinvestment would increase the volatility.

141. Fractional Reserve Banking and Insolvency
It certainly is possible for a run on the bank to drive it into insolvency.  And yes, if the bank makes some bad loans, it can magnify the problem. Generally, this does not happen, though.  Remember that banks usually have lots of customers, and people are depositing money and making mortgage payments every day, so there is usually enough on-hand to cover average banking withdrawl activity, regardless of any bad loans they have outstanding. Banks have lots of historical data to know what the average withdrawl demands are for a given day.  They also have risk models to predict the likelihood of their loans going into default.  A bank will generally use this information to strike a healthy balance between profit-making activity (e.g. issuing loans), and satisfying its account holders. In the event of a major withdrawl demand, there are some protections in place to guard against insolvency. There are regulations that specify a Reserve Requirement.  The bank must keep a certain amount of money on hand, so they can't take huge risks by loaning out too much money all at once.  Regulators can tweak this requirement over time to reflect the current economic situation. If a bank does run into trouble, it can take out a short-term loan.  Either from another bank, or from the central bank (e.g. the US Federal Reserve).  Banks don't want to pay interest on loans any more than you do, so if they are regularly borrowing money, they will adjust thier cash reserves accordingly. If all else fails and the bank can't meet its obligations (e.g. the Fed loan fell through), the bank has an insurance policy to make sure the account holders get paid.  In the US, this is what the FDIC is for.  Worst case, the bank goes under, but your money is safe. These protections have worked pretty well for many decades.  However, during the recent financial crisis, all three of these protections were under heavy strain.  So, one of the things banking regulators did was to put the major banks through stress tests to make sure they could handle several bad financial events without collapsing.  These tests showed that some banks didn't have enough money in reserve.  (Not long after, banks started to increase fees and credit card rates to raise this additional capital.) Keep in mind that if banks were unable to use the deposited money (loan it out, invest it, etc), the current financial landscape would change considerably.

142. What part of buying a house would make my net worth go down?
You can look at buying a house as being a long term investment in not paying rent.   In the short time there are costs to buying (legal, taxes, etc).   This depends on only buying house of the size/location you need e.g. no better then what you would have rented. House buying tent to work out best when there is high inflation, as the rent you would otherwise be paying goes up with  inflation – provided you can live with the short term pain of high interest rates.

143. How to make money from a downward European market?
If you want to make money while European equities markets are crashing and the Euro itself is devaluing: None of these strategies are to be taken lightly. All involve risk. There are probably numerous ways that you can lose even though it seems like you should win. Transaction fees could eat your profits, especially if you have only a small amount of capital to invest with. The worst part is that they all involve timing. If you think the crash is coming next week, you could, say, buy a bunch of puts. But if the crash doesn't come for another 6 months, all of your puts are going to expire worthless and you've lost all of your capital. Even worse, if you sell short an index ETF this week in advance of next week's impending crash, and some rescue package arrives over the weekend, equity prices could spike at the beginning of the week and you'd be screwed.

144. Is it inadvisable to leave a Roth IRA to charity upon death?
You need to keep in mind that there's an exemption amount of more than $5M (five million) dollars for estate tax. Unless you used all of it for gifts during your life time, it will more than cover all of your $70K estate, so there's no need in any additional planning. As to Roth vs Traditional IRA - if you want to leave something to your siblings, leave them the Roth. Why would you give the taxable income to your siblings when you can give them the nontaxable one? Charities are tax exempt anyway.

145. How to register LLC in the US from India? [duplicate]
Wyoming is a good state for this. It is inexpensive and annual compliance is minimal. Although Delaware has the best advertising campaign, so people know about it, the reality is  that there are over 50 states/jurisdictions in the United States with their own competitive incorporation laws to attract investment (as well as their own legislative bodies that change those laws), so you just have to read the laws to find a state that is favorable for you. What I mean is that whatever Delaware does to get in the news about its easy business laws, has been mimicked and done even better by other states by this point in time. And regarding Delaware's Chancery Court, all other states in the union can also lean on Delaware case law, so this perk is not unique to Delaware. Wyoming is cheaper than Delaware for nominal presence in the United States, requires less information then Delaware, and is also tax free. A "registered agent" can get you set up and you can find one to help you with the address dilemma. This should only cost $99 - $200 over the state fees. An LLC does not need to have an address in the United States, but many registered agents will let you use their address, just ask. Many kinds of businesses still require a bank account for domestic and global trade. Many don't require any financial intermediary any more to receive payments. But if you do need this, then opening a bank account in the United States will be more difficult. Again, the registered agent or lawyer can get a Tax Identification Number for you from the IRS, and this will be necessary to open a US bank account.  But it is more likely that you will need an employee or nominee director in the United States to go in person to a bank and open an account. This person needs to be mentioned in the Operating Agreement or other official form on the incorporation documents. They will simply walk into a bank with your articles of incorporation and operating agreement showing that they are authorized to act on behalf of the entity and open a bank account. They then resign, and this is a private document between the LLC and the employee. But you will be able to receive and accept payments and access the global financial system now. A lot of multinational entities set up subsidiaries in a number of countries this way.

146. Do I have to repay the First-Time Homebuyers tax credit if I refinance?
No. As long as you live in the house for 3 years, it's yours to keep. Financing has nothing to do with that.

147. Paid cash for a car, but dealer wants to change price
Let me get this straight. I would stand my ground. Your son negotiated in good faith. Either they messed up, or they are dishonest. Either way your son wasn't the one supposed to know all the internal rules. I don't think it matters if they cashed the check or not. I would tell them if they have cashed it, that is even more evidence the deal was finalized. But even if they they didn't cash it, it only proves they are very disorganized. If for some reason your son feels forced to redo the deal, have him start the negotiations way below the price that was agreed to.  If the deal for some strange reason gets voided don't let him agree to some sort of restocking fee.

148. Do people tend to spend less when using cash than credit cards?
Psychology Today had an interesting article from July 11, 2016, in which they go through the psychological aspects of using cash vs. a credit card. This article cites a 2008 paper in the Journal of Experimental Psychology: Applied that found: “the more transparent the payment outflow, the greater the aversion to spending or higher the ‘pain of paying’ …leading to less transparent payment modes such as credit cards and gift cards (vs. cash) being more easily spent or treated as play or ‘monopoly money.’” The article cites a number of other studies that are of interest on this topic as well.

149. Any difference between buying a few shares of expensive stock or a bunch of cheap stock
I was thinking that the value of the stock is the value of the stock...the actual number of shares really doesn't matter, but I'm not sure. You're correct.  Share price is meaningless.   Google is $700 per share, Apple is $100 per share, that doesn't say anything about either company and/or whether or not one is a better investment over the other. You should not evaluate an investment decision on price of a share.  Look at the books decide if the company is worth owning, then decide if it's worth owning at it's current price.
