Whats the difference between day trading and flipping and their tax implications?
Flipping usually refers to real-estate transaction: you buy a property, improve/renovate/rehabilitate it and resell it quickly. The distinction between flipper and investor is similar to the distinction between trader and investor, even though the tax code doesn't explicitly refer to house flipping. Gains on house flipping can be considered as active business gain or passive activity income, which are treated differently: passive income goes on Schedule E and Schedule D, active income goes on Schedule C. The distinction between passive and active is based on the characteristics of the activity (hours you spent on it, among other things). Trading income can similarly be considered as either passive (Schedule D/E treatment) or active (Schedule C treatment). Here's what the IRS has to say about traders: Special rules apply if you are a trader in securities, in the business   of buying and selling securities for your own account. This is   considered a business, even though you do not maintain an inventory   and do not have customers. To be engaged in business as a trader in   securities, you must meet all of the following conditions: The following facts and circumstances should be considered in   determining if your activity is a securities trading business: If the nature of your trading activities does not qualify as a   business, you are considered an investor... Investor, in this context, means passive income treatment (Schedule D/E). However, even if your income is considered active (Schedule C), stock sale proceeds are not subject to the self-employment tax. As you can see, there's no specific definition, but the facts and circumstances matter. You may be considered a trader by the IRS, or you may not. You may want to be considered a trader (for example to be able to make a mark-to-market election), or you may not. You should talk to a professional tax adviser (EA/CPA licensed in your State) for more details and suggestions.
"During the day, market and limit orders are submitted at any time by market participants and there is a bid and an ask that move around over time.  Trades occur whenever a market order is submitted or a limit order is submitted that at a price that matches or exceeds an existing limit order.  If you submit a market order, it may consume all best-price limit orders and you can get multiple prices, changing the bid or ask at the same time.  All that stuff happens during the trading day only. What happens at the end of the day is different.  A bunch of orders that were submitted during the day but marked as ""on close"" are aggregated with any outstanding limit orders to create a single closing price according to the algorithm established by the exchange.  Each exchange may handle the details of this closing event differently.  For example, the Nasdaq's closing cross or the NYSE's closing auction. The close is the most liquid time of the day, so investors who are trading large amounts and not interested in intraday swings will often submit a market-on-close or limit-on-close order.  This minimizes their chance of affecting the price or crossing a big spread.  It's actually most relevant for smaller stocks, which may have too little volume during the day to make big trades, but have plenty at the close.  In short, the volume you see is due to these on-close orders. The spike in volume most likely has no special information about what will happen overnight or the next day.  It's probably just a normal part of the market for illiquid stocks." &gt;Why not give extra tax breaks for the sale of stock purchased during a public offering (since that goes to helping the company) but not for secondhand (less necessary) trading  Because secondary trading determines how easy it is for companies to raise additional money and it also allows the company to manipulate private vs publicly held stakes in their company.  &gt;Should we give big tax breaks to people who lend businesses money?  There's a difference between lending money and investing in a corporation. Furthermore the income tax code when it comes to lending money via bonds is a complete mess. Corporate bond coupons are taxed like regular income (although the principal return is, of course, tax free). Federal and munis are taxed differently. There is also the advantage that you do get a tax break in the event of default, so any additional risk you take on has some marginal tax benefits. Congrats! Make sure you nail down NOW what happens to the house should you eventually separate. I know lots of unmarried couples who have stayed together for decades and look likely to do so for life; I've also seen some marriages break up that I wouldn't have expected to. Better to have this discussion NOW.  Beyond that: Main immediate implications are that you have new costs (taxes, utilities, maintenance) and new tax issues (mortgage interest and property tax deductability) and you're going to have to figure out how to allocate those between you (if there is a between; not sure whether unmarried couples can file jointly these days). "From what I have read from O'Neil to Van Tharp, etc, etc, no one can pick winners more than 75% of the time regardless of the system they use and most traders consider themselves successful if 60% of the trades are winners and 40% are losers.  So I am on the side that the chart is only a reflection of the past and cannot tell you reliably what will happen in the future. It is difficult to realize this but here is a simple way for you to realize it. If you look at a daily chart and let's say it is 9:30 am at the open and you ask a person to look at the technical indicators, look at the fundamentals and decide the direction of the market by drawing the graph, just for the next hour. He will realize in just a few seconds that he will say to him or her self ""How on earth do you expect me to be able to do that?""  He will realize very quickly that it is impossible to tell the direction of the market and he realizes it would be foolhardy to even try. Because Mickey Mantle hit over 250 every year of his career for the first 15 years it would be a prudent bet to bet that he could do it again over the span of a season, but you would be a fool to try to  guess if the next pitch would be a ball or a strike. You would be correct about 50% of the time and wrong about 50% of the time. You can rely on LARGER PATTERNS OF BEHAVIOR OVER YEARS, but short hourly or even minute by minute prediction is foolish. That is why to be a trader you have to keep on trading and if you keep on trading and cut your losses to 1/2 of your wins you will eventually have a wonderful profit.  But you have to limit your risk on any one trade to 1% of your portfolio.  In that way you will be able to trade at least 100 times.  do the math.  trade a hundred times.  lose 5% and the next bet gain 10%.  Keep on doing it. You will have losses sometimes of 3 or 4 in a row and also wins sometimes of 3 or 4 in a row but overall if you keep on trading even the best traders are generally only ""right"" 60% of the time.  So lets do the math. If you took 100 dollars and make 100 trades and the first trade you made 10% and reinvested the total and the second trade you lost 5% of that and continue that win/loss sequence for 100 trades you would have 1284 dollars minus commissions. That is a 1200% return in one hundred trades.  If you do it in a roth IRA you pay no taxes on the short term gains.  It is not difficult to realize that the stock market DOES TREND. And the easiest way to make 10% quickly is to in general trade 3x leveraged funds or stocks that have at least 3 beta from the general index.  Take any trend up and count the number of days the stock is up and it is usually 66-75% and take any down trend and it is down 66-75% of the days.  So if you bet on the the beginning of a day when the stock was up and if you buy the next day about 66-75% of the time the stock will also be up. So the idea is to realize that 1/3 of the time at least you will cut your losses but 2/3 of the time you will be up then next day as well.  So keep holding the position based on the low of the previous day and as the stock rises to your trend line then tighten the stock to the low of the same day or just take your profit and buy something else.  But losing 1/3 times is just part of ""the unpredictable"" nature of the stock market which is causes simply because there are three types of traders all betting at the same time on the same stock.  Day traders who are trading from 1 to 10 times a day, swing traders trading from 1 day to several weeks and buy and hold investors holding out for long term capital gains. They each have different price targets and time horizons and THAT DIFFERENCE is what makes the market move.  ONE PERSON'S SHORT TERM EXIT PRICE AT A PROFIT IS ANOTHER PERSONS LONG TERM ENTRY POINT and because so many are playing at the same time with different time horizons, stop losses and exit targets it is impossible to draw the price action or volume.  But it is possible to cut your losses and ride your winners and if you keep on doing that you have a very fine return indeed." A stock is only worth what someone is willing to pay for it. If it trades different values on different days, that means someone was willing to pay a higher price OR someone was willing to sell at a lower price.  There is no rule to prevent a stock from trading at $10 and then $100 the very next trade... or $1 the very next trade. (Though exchanges or regulators may halt trading, cancel trades, or impose limits on large price movements as they deem necessary, but this is beside the point I'm trying to illustrate). Asking what happens from the close of one day to the open of the next is like asking what happens from one trade to the next trade... someone simply decided to sell or pay a different price.  Nothing needs to have happened in between. Here are three key factors that you do not explicitly state: So while I cannot say exactly why the tax law is the way it is, I can infer that it encourages long-term investments rather than short-term, which would seem to be a good thing for society overall.  The fast that capital gains are taxed at all somewhat discourages cashing out investments (although I suspect it's more of a nuisance factor - the cash received is likely more on an incentive that the tax is a disincentive). Yes, if you can split your income up over multiple years it will be to your advantage over earning it all in one year.  The reasons are as you mentioned, you get to apply multiple deductions/credits/exemptions to the same income. Rather than just 1 standard deduction, you get to deduct 2 standard deductions, you can double the max saved in an IRA, you benefit more from any non-refundable credits etc. This is partly due to the fact that when you are filing your taxes in Year 1, you can't include anything from Year 2 since it hasn't happened yet. It doesn't make sense for the Government to take into account actions that may or may not happen when calculating your tax bill. There are factors where other year profit/loss can affect your tax liability, however as far as I know these are limited to businesses. Look into Loss Carry Forwarded/Back if you want to know more. Regarding the '30% simple rate', I think you are confusing something that is simple to say with something that is simple to implement.  Are we going to go change the rules on people who expected their mortgage deduction to continue? There are few ways I can think of that are more sure to cause home prices to plummet than to eliminate the Mortgage Interest Deduction. What about removing Student Loan Interest? Under a 30% 'simple' rate, what tools would the government use to encourage trade in specific areas? Will state income tax deduction also be removed? This is going to punish those in a state with a high income tax more than those in states without income tax. Those are all just 'common' deductions that affect a lot of people, you could easily say 'no' to all of them and just piss off a bunch of people, but what about selling stock though? I paid $100 for the stock and I sold it for $120, do I need to pay $36 tax on that because it is a 'simple' 30% tax rate or are we allowing the cost of goods sold deduction (it's called something else I believe when talking about stocks but it's the same idea?) What about if I travel for work to tutor individuals, can I deduct my mileage expenses? Do I need to pay 30% income tax on my earnings and principal from a Roth IRA? A lot of people have contributed to a Roth with the understanding that withdrawals will be tax free, changing those rules are punishing people for using vehicles intentionally created by the government. Are we going to go around and dismantle all non-profits that subsist entirely on tax-deductible donations? Do I need to pay taxes on the employer's cost of my health insurance? What about 401k's and IRA's? Being true to a 'simple' 30% tax will eliminate all 'benefits' from every job as you would need to pay taxes on the value of the benefits. I should mention that this isn't exactly too crazy, there was a relatively recent IRS publication about businesses needing to withhold taxes from their employees for the cost of company supplied food but I don't know if it was ultimately accepted. At the end of the day, the concept of simplifying the tax law isn't without merit, but realize that the complexities of tax law are there due to the complexities of life. The vast majority of tax laws were written for a reason other than to benefit special interests, and for that reason they cannot easily be ignored. "When a question is phrased this way, i.e. ""for tax purposes"" I'm compelled to advise - Don't let the tax tail wag the investing dog.  In theory, one can create a loss, up to the $3K, and take it against ordinary income. When sold, the gains may be long term and be at a lower rate. In reality, if you are out of the stock for the required 30 days, it will shoot up in price. If you double up, as LittleAdv correctly offers, it will drop over the 30 days and negate any benefit. The investing dog's water bowl is half full."
