understand taxes when geting money from a project built long time ago plus my full time job
You need to register as self-employed with HMRC (it is perfectly fine to be self-employed and employed by an employer at the same time, in exactly your kind of situation). Then, when the income arrives you will need to declare it on your yearly tax return.  HMRC information about registering for self-employment and declaring the income is here: https://www.gov.uk/working-for-yourself/overview There's a few extra hoops if your clients are outside the UK; the detail depends on whether they are in the EU or not. More details about this are here: https://www.gov.uk/online-and-distance-selling-for-businesses/selling-overseas .
You only pay tax on the capital gain of the bond, not the principal, unless the source of the money for the principal was gain from another investment, if that makes sense.   In other words, if you bought the bond with income earned from your job, that money was already taxed as income, so it isn't subject to taxation again when you redeem the bond.  On the other hand, if you cashed out of one investment and used those proceeds to buy a bond, then the entire amount might be taxable. "Can I deduct the money that I giving to my team mates from the taxes   that I pay? If yes, how should I record the transaction? Why? Why are you giving money to your team mates? That's the most important question, and any answer without taking this into account is not full. You would probably have to talk to a professional tax adviser (a CPA/EA licensed in your state) about the details, but in general - you cannot deduct money you give someone just because you feel like it. Moreover, it may be subject to an additional tax - the gift tax. PS: We don't have any partnership or something similar, it is just   each of us on his own. Assuming you want to give your team mates money because you developed the project together - then you do in fact have a partnership. In order to split the income properly, you should get a tax ID for the partnership, and issue a 1065 and K-1 for each team mate. In most states, you don't need to ""register"" a partnership with the state. Mere ""lets do things together"" creates a partnership. Otherwise, if they work for you (as opposed to with you in the case above), you can treat it as your own business income, and pay your team mates (who are now your contractors/employees) accordingly. Be careful here, because the difference between contractor and employee in tax law is significant, and you may end up being on the hook for a lot of things you're not aware of. Bottom line, in certain situation you cannot deduct, in others you can - you have to discuss it with a professional. Doing these things on your own without fully understanding what each term means - is dangerous, and IRS doesn't forgive for ""honest mistakes""." "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." "Take a look at IRS Publication 15. This is your employer's ""bible"" for withholding the correct amount of taxes from your paycheck. Most payroll systems use what this publication defines as the ""Percentage Method"", because it requires less data to be entered into the system in order to correctly compute the amount of withholding. The computation method is as follows: Taxes are computed ""piecewise""; dollar amounts up to A are taxed at X%, and then dollar amounts between A and B are taxed at Y%, so total tax for B dollars is A*X + (B-A)*Y. Here is the table of rates for income earned in 2012 on a daily basis by a person filing as Single: To use this table, multiply all the dollar amounts by the number of business days in the pay period (so don't count more than 5 days per week even if you work 6 or 7). Find the range in which your pay subject to withholding falls, subtract the ""more than"" amount from the range, multiply the remainder by the ""W/H Pct"" for that line, and add that amount to the ""W/H Base"" amount (which is the cumulative amount of all lower tax brackets). This is the amount that will be withheld from your paycheck if you file Single or Married Filing Separately in the 2012 TY. If you file Married Filing Jointly, the amounts defining the tax brackets are slightly different (there's a pretty substantial ""marriage advantage"" right now; withholding for a married person in average wage-earning range is half or less than a person filing Single.). In your particular example of $2500 biweekly (10 business days/pp), with no allowances and no pre-tax deductions: So, with zero allowances, your employer should be taking $451.70 out of your paycheck for federal withholding. Now, that doesn't include PA state taxes of 3.07% (on $2500 that's $76.75), plus other state and federal taxes like SS (4.2% on your gross income up to 106k), Medicare/Medicaid (1.45% on your entire gross income), and SUTA (.8% on the first $8000). But, you also don't get a refund on those when you fill out the 1040 (except if you claim deductions against state income tax, and in an exceptional case which requires you to have two jobs in one year, thus doubling up on SS and SUTA taxes beyond their wage bases). If you claim 3 allowances on your federal taxes, all other things being equal, your taxable wages are reduced by $438.45, leaving you with taxable income of $2061.55. Still in the 25% bracket, but the wages subject to that level are only $619.55, for taxes in the 25% bracket of $154.89, plus the withholding base of $187.20 equals total federal w/h of $342.09 per paycheck, a savings of about $110pp. Those allowances do not count towards other federal taxes, and I do not know if PA state taxes figure these in. It seems odd that you would owe that much in taxes with your withholding effectively maxed out, unless you have some other form of income that you're reporting such as investment gains, child support/alimony, etc. With nobody claiming you as a dependent and no dependents of your own, filing Single, and zero allowances on your W-4 resulting in the tax withholding above, a quick run of the 1040EZ form shows that the feds should owe YOU $1738.20. The absolute worst-case scenario of you being claimed as a dependent by someone else should still get you a refund of $800 if you had your employer withhold the max. The numbers should only have gotten better if you're married or have kids or other dependents, or have significant itemized deductions such as a home mortgage (on which the interest and any property taxes are deductible). If you itemize, remember that state income tax, if any, is also deductible. I would consult a tax professional and have him double-check all your numbers. Unless there's something significant you haven't told us, you should not have owed the gov't at the end of the year." "You're certainly referring to ""Ex Post Facto"" laws, and while the US is constitutionally prohibited from passing criminal laws that are retroactive, the US Supreme Court has upheld many tax laws that apply tax code changes retroactively. You might ask a similar question on Law.SE for a more thorough treatment of the legalities of congress passing those laws, but I will stick to the personal finance portion of the question. What this means is that you can't expect that the current tax laws will be in force in the future, and your investment/retirement plans should be as flexible as possible. You may wish to have some money in both Roth and traditional 401(k) accounts. You might not want to have millions of dollars in Roth accounts, because if congress does act to limit the tax benefits of those accounts, it will probably be targeting the larger balances. If you are valuing tax deductions, you should put slightly more weight on deductions that you can take today than deductions that would apply in the future. If you do find yourself in trouble because of a retroactive change, be sure to consult a tax lawyer that specializes in dealing with the IRS to possibly negotiate a settlement for a lower amount than the full tax bill that results from the changes." "From the IRS page on Estimated Taxes (emphasis added): Taxes must be paid as you earn or receive income during the year, either through withholding or estimated tax payments. If the amount of income tax withheld from your salary or pension is not enough, or if you receive income such as interest, dividends, alimony, self-employment income, capital gains, prizes and awards, you may have to make estimated tax payments. If you are in business for yourself, you generally need to make estimated tax payments. Estimated tax is used to pay not only income tax, but other taxes such as self-employment tax and alternative minimum tax. I think that is crystal clear that you're paying income tax as well as self-employment tax. To expand a bit, you seem to be confusing self-employment tax and estimated tax, which are not only two different things, but two different kinds of things.  One is a tax, and the other is just a means of paying your taxes. ""Self-employment tax"" refers to the Social Security and Medicare taxes that you must pay on your self-employment income.  This is an actual tax that you owe.  If you receive a W-2, half of it is ""invisibly"" paid by your employer, and half of it is paid by you in the form of visible deductions on your pay stub.  If you're self-employed, you have to pay all of it explicitly. ""Estimated tax"" does not refer to any actual tax levied on anyone.  A more pedantically correct phrasing would be ""estimated tax payment"".  Estimated taxes are just payments that you make to the IRS to pay tax you expect to owe.  Whether you have to make such payments depends on how much tax you owe and whether you've paid it by other means.  You may need to pay estimated tax even if you're not self-employed, although this would be unusual.  (It could happen, for instance, if you realized large capital gains over the year.)  You also may be self-employed but not need to pay estimated tax (if, for instance, you also have a W-2 job and you reduce your withholding allowances to have extra tax withheld). That said, if you earn significant income from self-employment, you'll likely have to make estimated tax payments.  These are prepayments of the income tax and Social Security/Medicare taxes you accrue based on your self-employment income. As Pete B. mentioned in his answer, a possible reason that your estiamtes are low is because some taxes have already been withheld from the paychecks you received so far during the year (while you were an employee).  These represent tax payments you've already made; you don't need to pay that money a second time, but you may need to make estimated tax payments for your income going forward." "How can I avoid this, so we are taxed as if we are making the $60k/yr that we want to receive?  You can't. In the US the income is taxed when received, not when used. If you receive 1M this year, taking out 60K doesn't mean the other 940K ""weren't received"". They were, and are taxable. Create a pension fund in the corporation, feed it all profits, and pay   out $60k/yr of ""pension"". I doubt that the corporation could deduct a   million a year in pension funding. You cannot do that. You can only deposit to a pension plan up to 100% of your salary, and no more than $50K total (maybe a little more this year, its adjusted to inflation). Buy a million dollars in ""business equipment"" of some sort each year   to get a deduction, then sell it over time to fund a $60k/yr salary. I   doubt such a vehicle exists. If there's no real business purpose, it will be disallowed and you'll be penalized. Your only purpose is tax avoidance, meaning you're trying to shift income using your business to avoid paying taxes - that's illegal. Do crazy Section 79 life insurance schemes to tax-defer the income.   The law caps this so I can only deduct < $100k of the $1 million   annually, and there are other problems with this approach.\ Yes. Wouldn't go there.  Added: From what I understand, this is a term life insurance plan sponsored by the employer for the employee. This is not a deferral of income, but rather a deduction: instead of paying your term life insurance with your own after tax money, your employer pays with their pre-tax. It has a limit of $50K per employee, and is only available for employees. There are non-discrimination limitations that may affect your ability to use it, but I don't see how it is at all helpful for you. It gives you a deduction, but its money spent, not money in your pocket. End added. Do some tax avoidance like Facebook does with its Double Irish trick,   storing the income in some foreign subsidiary and drawing $60k/yr in   salary to be taxed at $60k/yr rates. This is probably cost-prohibitive   for a $1MM/yr company. You're not Facebook. What works with a billion, will not work with a million. Keep in mind that you're a one-man business, things that huge corporations like Google or Facebook can get away with are a no-no for a sole-proprietor (even if incorporated). Bottom line you'll probably have to pay the taxes. Get a good tax professional to help you identify as much deductions as possible, and if you can plan income ahead - plan it better." "I would suggest you pay quarterly. Or, if you prefer, do the extra withholding. Don't wait until the end of the year. My experience is that of having a day job with freelance work on the side. I've spent a few years just freelancing, and I paid quarterly as requested to avoid the penalties. Now that I have a good day job again, my freelancing is just a small part of my income, and so I end up with a net return and no longer have to pay quarterly. You shouldn't wait until the end of the year to pay. This is assuming your wife is bringing in a decent income. The only scenario where you would want to wait is if her income is only a small amount (such as my wife's plans for an Etsy store). To the IRS, it doesn't really make a difference whether you withhold extra or pay quarterly. Of those two choices, my preference is to pay quarterly - it's easy to set up calendar reminders on the quarterly payment dates, which are always the same. I did the same as bstpierre when estimating my payments: just take last year's tax (for the business) and divide by 4 (adjusting for any obvious situational differences). That's usually close enough. Paying quarterly instead of via withholding means you get to hold on to your money (on average) for 6 weeks longer. Granted, that doesn't mean much with today's interest rates, but it's something. You may prefer the simpler accounting for withholding, though - you can ""set and forget""." I just scanned in a single sheet summary of my last two years tax returns. It is something our CPA does for us. How would I post it? Don't worry, I marked out all the personal information.    What is says is I paid over $50K in taxes in 2015. Last year we had one of our biggest contracts put on hold, so I only paid $20K.   I won't have this years figures, because we don't submit them to our CPA until the end of the year. However, this year, we just bought out two other owners at $1.2M, which makes me a 33% owner. The contract is getting restarted (knock on wood), which all together means my personal tax liability is going to be well over $100K.   My company is a commercial company, but we work with the government, and matter of fact some of the stuff we produce was designed and developed by the government (as is many of today's modern inventions - I think you would be surprised).   So lets tackle it one at a time. Pick one of those things that commercial does better than government.   P.s. Higher taxes doesn't mean higher for you, a lot of times it means higher for guys like me or way better than me (which I am perfectly fine with, and matter of fact would support). People who use infastructure more - like large corporations - should pay more for it... "A bank may not like loaning money to you for this. That is one snag. You listed 500,000-600,000$ for a monster of a house (3000 sqft is over three times the average size of homes a hundred years ago). Add in the price of the land at 60K (600K divided ten ways). Where I live, there is a 15% VAT tax on new homes. I can't find out if California imposes a VAT tax on new homes. Anyway, returning back to the topic, because of the risk of loaning you 660K for a piece of land and construction, the bank may only let you borrow half or less of the final expected cost (not value). Another huge snag is that you say in a comment to quid ""I came up with this conclusion after talking to someone who had his property built in early 2000s in bay area for that average price"". Let's apply 3% inflation over 15 years to that number of 200$/sqft. That brings the range for construction costs to 780K-930K. Even at 2% inflation 670K-810K. Edit: OP later expanded the question making it an inquiry on why people don't collaborate to buy a plot of land and build their homes. ""Back in the day"" this wasn't all that atypical! For example, my pastor's parents did just this when he was a young lad. Apart from the individual issues mentioned above, there are sociological challenges that arrive. Examples: These are the easy questions." "If you only have to pay 23k federal taxes on 100k, that means you are in the long term capital gains tax rate, which is the lower of the tax rates available. First you get your federal income tax marginal tax rate, and then find the matching long term capital gains tax rate. For example, if your marginal federal income tax rate is 28%, your capital gains tax rate would be 15%. Or rather, if the amount of the gain would put you in the 28% rate, then your long term capital gains tax rate is 15%. You can reduce that by having more losses. If you have anything else invested anywhere that is taking a loss, then you can sell that this year and it will offset the other gains you have realized. The only note is that your losses have to be long term capital losses too. Tax loss harvesting takes this to an extreme where you sell something at a loss to lock in the tax loss, but you didn't really want to get rid of that investment, so then you buy a nearly identical investment. ie. if you owned shares of ""Direxion Tech Sector ETF"" and it was at a loss, you would sell that and then immediately buy ""ProShares Tech Sector ETF"", the competing product that does the exact same thing. Then there is charity. This still requires spending money and you not having it any longer. If you feel that a cause can use the money more directly than the US government, you can donate an appreciated asset to the charity - not report a gain and also take a charitable deduction." You have two different operations going on: They each have of a set of rules regarding amounts, timelines, taxes, and penalties. The excess money can't be recharacterized except during a specific window of time.  I would see a tax professional to work through all the details. Is this an inheritance (tax-free) or is it taxable income from a large project?  I won't argue with knocking out the student loan, it's a monthly payment that's nice to get rid of.  You make no mention of your age or your current retirement assets. Call me boring, but if I were handed $100K it would simply be added to the mix. A conservative withdrawal rate of 4%/yr, means that $100K to me is really a $4K annual income. That makes it seem like far less of a windfall, I know.  The problem I see in your question is that there's an inclination to 'do something' with it all. You've already trimmed it down to $40,000. As a freelancer with income that's probably not steady why not just start to put it aside for the long term. In good income years, a pretax account, in low income years, use a Roth IRA. As littleadv asks - what are your plans if any to buy a house? $40K may not even be a full downpayment. Assuming that what you want to do is to counter the capital gains tax on the short term and long term gains, and that doing so will avoid any underpayment penalties, it is relatively simple to do so. Figure out the tax on the capital gains by determining your tax bracket. Lets say 25% short term and 15% long term or (0.25x7K) + (0.15*8K) or $2950.  If you donate to charities an additional amount of items or money to cover that tax. So taking the numbers in step 1 divide by the marginal tax rate $2950/0.25 or $11,800.  Money is easier to donate because you will be contributing enough value that the IRS may ask for proof of the value, and that proof needs to be gathered either before the donation is given or at the time the donation is given. Also don't wait until December 31st, if you miss the deadline and the donation is counted for next year, the purpose will have been missed. Now if the goal is just to avoid the underpayment penalty, you have two other options.  The safe harbor is the easiest of the two to determine. Look at last years tax form. Look for the amount of tax you paid last year. Not what was withheld, but what you actually paid. If all your withholding this year, is greater than 110% of the total tax from last year, you have reached the safe harbor. There are a few more twists depending on AGI Special rules for farmers, fishermen, and higher income taxpayers.   If at least two-thirds of your gross income for tax year 2014 or 2015   is from farming or fishing, substitute 662/3% for 90% in (2a) under   the General rule, earlier. If your AGI for 2014 was more than $150,000   ($75,000 if your filing status for 2015 is married filing a separate   return), substitute 110% for 100% in (2b) under General rule ,   earlier. See Figure 4-A and Publication 505, chapter 2 for more   information. "First of all congrats... very nice work indeed..  Secondly, i do not offer this as legal advise.. lol.. anyhow.. you need to make sure to hang on to as much as possible, being a single earner, our Uncle (Sam) is going to want what's due... That being said, you should probably look into investments, for starters, purchase a primary residence or start a business, or purchase a primary residence and use that as a business residence (both).. what you basically want are write-offs.. you need to bring your ""taxable"" income as low as possible so you pay minimal taxes.. in your case, you're in danger of paying a hefty sum in taxes... i'm sure you can shield yourself with various business expenses (a car, workplace, computers, etc.. ) that you could benefit from, both professionally and individually.. and then seriously bro... making 250k leads me to believe you've got at least more than half a brain, and that you're using more than half of that.. so dude.. get an accountant... and one you can trust.. ask your parents, colleagues, people you've worked with in the past.. etc.. there are professionals who are equally as talented in helping you keep your money as you are in making it.. -OR- you could get married, make sure your wife stays at home and start popping out kids asap... those keep my taxable (and excess) income pretty low.. LOL!!! I'm going to add to this... as a contractor, i've generally put any ""estimated"" taxes into some kind of interest accruing account so i can at least make a little money before i have to give it away.. in your case, i'd say put away at least 2/3's into some kind of interest earning account.. start by talking to your personal banker wherever your money is.. you'll be surprised at how nice they treat you... you ARE going to have to pay taxes.. so until you do, try to make a little money while it sits..  again, nice problem to have!"
