As a minor in the UK do I need to pay taxes on self-employment income, and if so how?
"As a minor you certainly can pay tax, the government wants its cut from you just like everyone else :-) However you do get the personal allowance like everyone else, so you won't have to pay income tax until your net income reaches £10,800 (that's the figure for the tax year from April 2015 to April 2016, it'll probably change in future years). Once you're 16, you will also have to pay national insurance, which is basically another tax, at a lower threshold. The current rates are £2.80/week if you are making £5,965 a year or more, and also 9% on any income above £8,060 (up to £42,385). Your ""net income"" or ""profits"" are the income you receive minus the expenses you have to support that income. Note that the expenses must be entirely for the ""business"", they can't be for personal things. The most important thing to do immediately is to start keeping accurate records. Keep a list of the income you receive and also the expenses you pay for hardware etc. Make sure you keep receipts (perhaps just electronic ones) for the expenses so you can prove they existed later. Keep track of that net income as the year goes on and if it starts collecting at the rate you'd have to pay tax and national insurance, then make sure you also put aside enough money to pay for those when the bill comes. There's some good general advice on the Government's website here: https://www.gov.uk/working-for-yourself/what-you-need-to-do In short, as well as keeping records, you should register with the tax office, HMRC, as a ""sole trader"". This should be something that anyone can do whatever their age, but it's worth calling them up as soon as you can to check and find out if there are any other issues. They'll probably want you to send in tax returns containing the details of your income and expenses. If you're making enough money it may be worth paying an accountant to do this for you."
"Littleadv is incorrect because receiving a 1099 means she will be taxed self-employment tax on top of federal income taxes. Your employer will automatically withhold 7.65% of payroll taxes as they pay you each paycheck and then they'll automatically pay the other half of your payroll tax (an additional 7.65%) to bring it to a total of 15.3%. In other words, because your wife is technically self employed, she will owe both sides of payroll tax which is 15.3% of $38k = $5,800 on TOP of your federal income tax (which is the only thing the W-4 is instructing them about what amount to withhold). The huge advantage to a 1099, however, is that she's essentially self-employed which means ALL of the things she needs to run her business are deductible expenses. This includes her car, computer, home office, supplies, sometimes phone, gas, maintenance, travel expenses, sometimes entertainment, etc - which can easily bring her ""income"" down from $38k to lets say $23k, reducing both her federal income tax AND self-employment tax to apply to $15k less (saving lets say 50% of $15k = $7.5k with federal and self employment because your income is so high). She is actually supposed to pay quarterly taxes to make up for all of this. The easy way to do this is each quarter plug YOUR total salary + bonus and the tax YOU have paid so far (check your paystubs) into TurboTax along with her income so far and all of her expenses. This will give you how much tax you can expect to have left to owe so far--this would be your first quarter. When you calculate your other quarters, do it the exact same way and just subtract what you've already paid so far that year from your total tax liability." How you pay Income Tax Pay As You Earn (PAYE) Most people pay Income Tax through PAYE. This is the system your employer or pension provider uses to take Income Tax and National Insurance contributions before they pay your wages or pension. Your tax code tells your employer how much to deduct. Your tax code can take account of state benefits, so if you owe tax on them (eg the State Pension) it’s usually taken automatically from your other income. Self Assessment tax returns If your financial affairs are more complex (eg you’re self-employed or have a high income) you may pay Income Tax and National Insurance through Self Assessment. You’ll need to fill in a tax return every year. Income Tax on savings and investment interest Income Tax is usually taken from interest on savings and investments automatically. Income that’s not automatically taxed You must fill in a tax return if your untaxed income is over £2,500, or if you don’t pay tax through your wages or pension. You must contact the Income Tax helpline if it’s less than £2,500. "Yes. You do have to pay taxes in the UK as well but it depends on how much you have already been taxed in the US. http://taxaid.org.uk/situations/migrant-workernew-to-the-uk/income-from-abroad-arising-basis-vs-remittance-basis Say, you have to pay 20% tax in the UK for your earnings here. You ARE required to pay the same percentage on your foreign income as well. Now, if your ""home"" country already taxed you at 10% (for the sake of example), then you only need to pay the ""remaining"" 10% in the UK. However, the tax law in the UK does allow you to choose between ""arising"" basis and ""remittance"" basis on your income from the country you are domiciled in. What I have explained above is based on when income ""arises."" But the laws are complicated, and you are almost always better off by paying it on ""arising"" basis." "Employers withhold at rates specified in Circular E issued by the IR. You can request that  additional money be withheld (not an issue here) or you can have  reduced withholding by claiming additional allowances on a W-4 (i.e.,  more than just for you and spouse and dependents) if you believe that  this will result in withholding that will more closely match the tax due.  (Note added in edit):Page 2 of the W-4 form has worksheets that can be used to figure out how many additional allowances to request. Also, I wonder if your withholding will be 37% or final tax bill be  26% of your adjusted gross income.  The tax brackets are the tax  on marginal income. If you are in the 28% tax bracket, you owe 28 cents in tax for each additional dollar of income, not 28 cents in tax for every dollar of income.  Your overall tax might well be less than 20% of your income.  As a specific example, in 2011 a married taxpayer filing jointly would be in the  (highest) 35% tax bracket if the taxable income was $379,150 or more (marginal tax rate of 35% is applicable to every dollar more than $379,150) but the tax on  $379,150 itself works out to be $102,574 or 27.05% of the taxable income. So if you do expect to be earning around $350K or more in salary between now and December 31 to hit that 26% that you expect you will owe, you might want to consider paying a tax accountant for advice on how to fill out your W-4 form for your new employer rather than relying on an Internet forum such as this for free advice. Note added in edit:  Your comment ""... it is a cocktail of ... federal taxes, state taxes, local taxes, health care ..."" on the earlier version of my answer does raise the question of whether you want your employer to withhold 26% instead of 37% and have the money go to meet all these obligations or just 26% towards your Federal income tax liability only. The Federal W-4 form affects only how much money is withheld from your paycheck and sent to the US Treasury.  Some of the money that each of your employers withholds (Social Security and Medicare taxes) is not affected by what you put down on  the W-4 form.  Now, if you hold two jobs and the total income shown on your W-2s is larger than the SS limit, you will  have had too much Social Security taxes withheld, and the excess will be a credit towards your Federal income tax liability.  You have self-employment income too on which you owe Social Security and Medicare taxes and you are making estimated tax payments. The excess Social Security tax payment can count towards this too (as well as income tax on your Schedule C income).  Thus, if your new employer is withholding too much, you might be able to skip making the fourth quarterly payment of estimated tax or make a reduced payment (there is no requirement that the four installments  must be equal).  In short, there are lots of ramifications that you need to take into account before deciding that 26% is the right number. Instead of filling out a W-4  all by yourself right away, I strongly recommend  reading up a lot on income taxes, or play with a tax preparation program (last year's version will do a pretty good job of at least getting you in the right ballpark), or consult with a tax accountant." "I think the key point that's making the other commenters misunderstand each other here is the concept of ""deductions"". I can only speak for the UK, but that's only a concept that business owners would understand in this country.  For things like child credits or low income tax credits, we don't get paid them at the end of the tax year, but into our bank accounts every couple of weeks all year round. Therefore, we have nothing to ""deduct"". If we work for a company and have business expenses, then the company pays for them. If we make interest on our savings, the bank pays it for us. We make money at our jobs, and the employer works out what taxes and national insurance we owe, based on a tax code that the government works out for us annually (which we can challenge).  To be fair, it's not like we're free from bureaucracy if we want to claim these benefits. There are often lots of forms if you want child benefit or disability allowances, for instance. We just apply as soon as we're eligible, rather than waiting to get a lump sum rebate. So it appears to be a very different system, and neither is inherently better than the other (though I'm personally glad I don't usually have to fill in a big tax return myself, which I only did one year when I was self employed). I'd be interested to know, since Google has let me down, which countries use the American system, and which the British or Czech." Since your YouTube income is considered self-employment income and because you probably already made more than $400 in net income (after deducting expenses from the $4000 you've received so far), you will have to pay self-employment tax and file a return.  This is according to the IRS's Publication 17 (2016), Your Federal Income Tax, so assumes the same rules for 2016 will remain in effect for 2017: You are self-employed if you: Carry on a trade or business as a sole proprietor, Are an independent contractor, Are a member of a partnership, or Are in business for yourself in any other way. Self-employment can include work in addition to your regular full-time business activities, such as certain part-time work you do at home or in addition to your regular job. You must file a return if your gross income is at least as much as the filing requirement amount for your filing status and age (shown in Table 1-1). Also, you must file Form 1040 and Schedule SE (Form 1040), Self-Employment Tax, if: Your net earnings from self-employment (excluding church employee income) were $400 or more, or You had church employee income of $108.28 or more. (See Table 1-3.) Use Schedule SE (Form 1040) to figure your self-employment tax. Self-employment tax is comparable to the social security and Medicare tax withheld from an employee's wages. For more information about this tax, see Pub. 334, Tax Guide for Small Business. I'd also note that your predicted income is getting close to the level where you would need to pay Estimated Taxes, which for self-employed people work like the withholding taxes employers remove their employees paychecks and pay to the government. If you end up owing more than $1000 when you file your return you could be assessed penalties for not paying the Estimated Taxes. There is a grace period if you had to pay no taxes in the previous year (2016 in this case), that could let you escape those penalties. "This page lays down the requirements for an ""unincorporated association"" to pay tax (i.e. any group that's not a registered entity). You pay tax is you make money from: it looks like you don't do any of those, so you don't need to file for taxes. There is another exemption that you don't have to file if it is likely that you would owe less than a hundred pounds taxes, which would also probably apply to you. There are many thousands of clubs and societies in the UK that don't need to register for tax purposes, so you are far from alone. It is probably worth creating an actual club (""Captain Insanity Server Club"") and keeping records of donations and expenses for the server. There isn't any need to legally incorporate or anything like that, though you might try having a separate bank account for it if you can get a free one, so that if the tax authorities ever audit you personally you can show them that the donations you received weren't income to you." Unless you're running a self-employed business with a significant turnover (more than £150k), you are entitled to use cash basis accounting for your tax return, which means you would put the date of transactions as the payment date rather than the billing date or the date a debt is incurred. For payments which have a lag, e.g. a cheque that needs to be paid in or a bank transfer that takes a few days, you might also need to choose between multiple payment dates, e.g. when you initiated the payment or when it took effect. You can pick one as long as you're consistent: You can choose how you record when money is received or    paid (eg the date the money enters your account or the date a cheque   is written) but you must use the same method each tax year.
