Tax withheld by USA working in UK (Form 1042-S and Form 1099)
"The shares are ""imputed income"" / payment in kind. You worked in the UK, but are you a ""US Person""? If not, you should go back to payroll with this query as this income is taxable in the UK. It is important you find out on what basis they were issued. The company will have answers. Where they aquired at a discount to fair market value ? Where they purchased with a salary deduction as part of a scheme ? Where they acquired by conversion of employee stock options ?    If you sell the shares, or are paid dividends, then there will be tax withheld." Why was I sent both 1042-S and 1099. Which amount is the right amount that has been withheld. Generally, each tax form you get will be about a separate income; for instance, you might get a 1099-DIV for dividends you earned from an investment and then a 1099-B for the profit or loss on selling that investment, in which case you'd report them both to the IRS. In this case, you've also had money withheld as a non-resident alien, which is why you've been issued a 1042-S. So you need to report both amounts to the IRS.
You are right that even if you do not receive a 1099-MISC, you still need to report all income to the IRS.  Report the $40 on Schedule C or Schedule C-EZ.  Since your net profit was less than $400, you do not need to file Schedule SE.  From the IRS web site: Self-Employment Income It is a common misconception that if a taxpayer does not receive a Form 1099-MISC or if the income is under $600 per payer, the income is not taxable. There is no minimum amount that a taxpayer may exclude from gross income. All income earned through the taxpayer’s business, as an independent contractor or from informal side jobs is self-employment income, which is fully taxable and must be reported on Form 1040. Use Form 1040, Schedule C, Profit or Loss from Business, or Form 1040, Schedule C-EZ, Net Profit from Business (Sole Proprietorship) to report income and expenses. Taxpayers will also need to prepare Form 1040 Schedule SE for self-employment taxes if the net profit exceeds $400 for a year. Do not report this income on Form 1040 Line 21 as Other Income. Independent contractors must report all income as taxable, even if it is less than $600. Even if the client does not issue a Form 1099-MISC, the income, whatever the amount, is still reportable by the taxpayer. As @littleadv's comment on your question said, it is unlikely that you and your husband paid a total of $5K in income tax on $185K of wages in 2013. More likely, your 2013 tax return (assumed to be a Married Filing Jointly tax return) showed that you had not arranged to have  enough tax withheld from your salaries and thus you still owed $5K  to the IRS for 2013 taxes. Most likely, that $5K sum included not just the unpaid amount of tax but also  penalties for not paying enough income tax during 2013 and interest on the amounts not paid on time.  Just to be clear, note that the income tax you paid for 2013 during 2013 is the total of all income tax withheld from your wages by your employers (plus any estimated tax payments that you might have made for 2013). If your 2014 tax return (that you will be filing by April 15, 2015)  will likely show a similar amount due for 2014 taxes, you can avoid  the penalties and interest by increasing  your income tax withholding by a substantial amount for the remainder of 2014. If you are paid monthly and have two paychecks still to be received, then having $2500 extra withheld from each paycheck will cover the $5K shortfall that you expect to have for 2014 taxes. I assume that this is what your husband intended you to do, and to do  this, you need to fill out a new W-4 Form (asking that an addiitonal  $2500 be withheld from each paycheck) and give this form to your employer soon (i.e. well before Payroll processes your next paycheck which usually happens a few days before you get the paycheck).  If you do so, your take-home pay will be reduced by $2500 on each of the next two monthly paychecks because your employer will withhold this extra amount from your pay and include it in the amount sent to the IRS as income tax withheld from your paycheck. After your last paycheck for 2014 has been received, you should submit a new W-4 Form to your asking for only $417 in extra income tax to be withheld from each paycheck starting January 1, 2015, so that  the expected $5K shortfall for 2015 is paid in 12 equal monthly installments. If you neglect to do this, your employer will continue to withhold $2500 extra as income tax, and you will get $2500 less in take-home pay month after month in 2015. This money will not disappear forever; come 2016 when you file your income tax return for 2015, you will receive a substantial refund because you overpaid income tax by a lot during 2015. You will not, however, receive any interest on the amount that the IRS is returning to you unless the IRS delays in sending you the refund for some reason.  Alternatively, you can file a new W-4 asking for no additional tax to be withheld from 2015 paychecks, and a year from now, go through the same exercise as above: have $2500 extra withheld from the last two paychecks for 2015, right when the holidays are coming and people are shopping for gifts. Your clients should not send you 1099-MISC if they paid with a credit card. You can refer them to this text in the instructions for the form 1099-MISC: Payments made with a credit card or payment card and certain other   types of payments, including third party network transactions, must be   reported on Form 1099-K by the payment settlement entity under section   6050W and are not subject to reporting on Form 1099-MISC. See the   separate Instructions for Form 1099-K. By sending out the 1099-MISC, your clients are essentially saying that they paid you directly (check or cash) in addition to the payment they made with a credit card (which will be reported on 1099-K). In case of an audit, you'll have trouble convincing the IRS that it didn't happen. I suggest asking the clients not to do this to you, since it may cost you significant amounts to fight the IRS later on. In any case, you report on your tax return what you really got, not what the 1099 says. If you have two 1099's covering the same income - there's no legal obligation to report the income twice. You do not have to pay twice the tax just because you have stupid clients. But you may have troubles explaining it to the IRS, especially if you're dealing with cash in your business. If you want to avoid matching issues, consider reporting all the 1099s, and then subtracting the duplicates and attaching a statement (the software will do it automatically when you add the description in the miscellaneous item) about what it is. 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. "The decision whether this test is or is not met seems to be highly dependent on the specific situation of the employer and the employee.  I think that you won't find a lot of general references meeting your needs. There is such a thing as a ""private ruling letter,"" where individuals provide specific information about their situation and request the IRS to rule in advance on how the situation falls with respect to the tax law.  I don't know a lot about that process or what you need to do to qualify to get a private ruling.  I do know that anonymized versions of at least some of the rulings are published.  You might look for such rulings that are close to your situation. I did a quick search and found two that are somewhat related: As regards your situation, my (non-expert) understanding is that you will not pass in this case unless either (a) the employer specifies that you must live on the West Coast or you'll be fired, (b) the employer would refuse to provide space for you if you moved to Boston (or another company location), or (c) you can show that you could not possibly do your job out of Boston.  For (c), that might mean, for example, you need to make visits to client locations in SF on short-notice to meet business requirements.  If you are only physically needed in SF occasionally and with ""reasonable"" notice, I don't think you could make it under (c), although if the employer doesn't want to pay travel costs, then you might still make it under (a) in this case." Welcome to the working world.  I will answer these a bit out of order. C)  Your withholding has almost zero chance of being correct.  Just about everyone has to pay or gets a refund.  I typically shoot for +- of $1000, and that is tough. A)  Your W-2 is where you adjust the amount of tax that is withheld.  You should fill out a new one as soon as possible.  You can use a paycheck calculator to figure out the proper tax that should be withheld.   B) No. D)  Yes you will owe Utah state tax.  See this site. The rub of this all is that you may have to pay Idaho tax prior to being refunded your Federal.  If you want to avoid this file your federal return as soon as possible (Goal:  File by 7 Feb).  You should have the return in 3 weeks or less (presuming you are owed one).  That will give you plenty of time to file and pay any Idaho tax owed.   I say all of this because you may be tempted to go to a tax preparation shop and take an advance on your income tax return.  Those loans are for people that hate money and are designed to tempt the foolish.  They are only slightly better than payday loans. "I've been highly compensated for a while now, and I have never used a tax professional.  My past complications include the year that my company was bought by a VC firm and my stock options and stock held were bought out to the tune of 5x my salary.  And now I have two kids in college, with scholarships, and paying the remainder out of 529 accounts. Usually, I don't even use tax software.  My typical method is to use the online software -- like turbotax online -- and let it figure out where I am.  Then I use the ""Free File Fillable forms"" online to actually complete the process.  Search for ""Free File Fillable Forms"" -- it's not the same as using turbotax or TaxAct for free.   My suggestion to you:  download the PDF form of 1040EZ and 1040A from the IRS.  Print the EZ, and fill it out.  This will give you a better feel for what exactly is going on.  With your income, I don't think you can file the EZ, but it's a good way to get your feet wet. The way income taxes work here in the US: According to the IRS, the Personal Exemption this year is worth $4,050, and the Standard Deduction $6,300, assuming you're single.   Lets assume that your salary will be in fact 75,000, and you don't pay for any benefits, but you do make a 401k contribution of 15% of your salary.  Then your W-2 at the end of the year should tell you to put 63,750 in a particular box on your 1040 form.  (63,750 is 85% of 75,000).  Lets then assume 63,750 is your AGI after other additions and subtractions.  63,750 - 4,050 - 6,300 == 53,400. The federal Tax system is graduated, meaning there are different ranges (brackets) with different percentages.  The term tax people use for taxable income of 53,400 is ""marginal tax rate""...so the last dollar they tax at 25%.  Other dollars less.  According to the IRS, if you're single, then on 53,400, you pay ""$6,897.50 plus 25% of the amount over $50,400""  Or 6897.50 + 750, or 7647.50. Note this is only Federal Income Tax.  You will also be paying Social Security and Medicare payroll Tax.  And I'm guessing you'll also be paying colorado state income tax.  Each state has its own forms and methods for figuring out the taxes and stuff. By the way, when you start, you'll fill out a ""W-4"" form to ""help"" you figure out how much to withhold from every paycheck.  (I find the W-4 is not helpful at all).  Your company will withhold from your paycheck some mysterious amount, and the process of filling out your 1040A or 1040EZ or whatever will be, likely, to get the over-withheld amount back." Do I pay tax to the US and then also pay it in India for my income, or   does my American partner, who holds 15% of the monthly income, pay tax   in the US for his income? Of course you do, what kind of question is this? You have income earned in the US by a US entity, and the entity is taxed. Since LLC is a disregarded entity - the tax shifts to you personally. You should file form 1040NR. You should also talk to a tax professional who's proficient in the Indo-US tax treaty, since it may affect your situation.
