What do I do with a P11D Expenses & Benefits form?
"The P11D is a record of the total benefits you've received in a tax year that haven't been taxed in another way, a bit like the P60 is a record of the total pay and tax you've paid in a tax year. Note that travel for business purposes shouldn't be taxable, and if that's what's being reported on the P11D you may need to make a claim for tax relief to HMRC to avoid having to pay the tax. I'm not sure whether it's normal for such expenses to be reported there. HMRC will normally collect that tax by adjusting your tax code after the P11D is issued, so that more tax is taken off your future income. So you don't need to do anything, as it'll be handled automatically. As to how you know it's accurate, if you have any doubts you'd need to contact your former employer and ask them to confirm the details. In general you ought to know what benefits you actually received so should at least be able to figure out if the number is plausible. If your ""travel"" was a flight to the USA, then probably it was. If it was a bus ticket, less so :-) If you fill in a tax return, you'll also have to report the amount there which will increase the tax you owe/reduce your refund. You won't be charged twice even if your tax code also changes, as the tax return accounts for the total amount of tax you've already paid. For travel benefits, the exact treatment in relation to tax/P11Ds is summarised here."
"I would suggest to get an authoritative response from a CPA. In any case it would be for your own benefit to have at least the first couple of years of tax returns prepared by a professional. However, from my own personal experience, in your situation the income should not be regarded as ""US income"" but rather income in your home country. Thus it should not appear on the US tax forms because you were not resident when you had it, it was given to you by your employer (which is X(Europe), not X(USA)), and you should have paid local taxes in your home country on it." "I've done various side work over the years -- computer consulting, writing, and I briefly had a video game company -- so I've gone through most of this. Disclaimer: I have never been audited, which may mean that everything I put on my tax forms looked plausible to the IRS and so is probably at least generally right, but it also means that the IRS has never put their stamp of approval on my tax forms. So that said ... 1: You do not need to form an LLC to be able to claim business expenses. Whether you have any expenses or not, you will have to complete a schedule C. On this form are places for expenses in various categories. Note that the categories are the most common type of expenses, there's an ""other"" space if you have something different. If you have any property that is used both for the business and also for personal use, you must calculate a business use percentage. For example if you bought a new printer and 60% of the time you use it for the business and 40% of the time you use it for personal stuff, then 60% of the cost is tax deductible. In general the IRS expects you to calculate the percentage based on amount of time used for business versus personal, though you are allowed to use other allocation formulas. Like for a printer I think you'd get away with number of pages printed for each. But if the business use is not 100%, you must keep records to justify the percentage. You can't just say, ""Oh, I think business use must have been about 3/4 of the time."" You have to have a log where you write down every time you use it and whether it was business or personal. Also, the IRS is very suspicious of business use of cars and computers, because these are things that are readily used for personal purposes. If you own a copper mine and you buy a mine-boring machine, odds are you aren't going to take that home to dig shafts in your backyard. But a computer can easily be used to play video games or send emails to friends and relatives and lots of things that have nothing to do with a business. So if you're going to claim a computer or a car, be prepared to justify it. You can claim office use of your home if you have one or more rooms or designated parts of a room that are used ""regularly and exclusively"" for business purposes. That is, if you turn the family room into an office, you can claim home office expenses. But if, like me, you sit on the couch to work but at other times you sit on the couch to watch TV, then the space is not used ""exclusively"" for business purposes. Also, the IRS is very suspicious of home office deductions. I've never tried to claim it. It's legal, just make sure you have all your ducks in a row if you claim it. Skip 2 for the moment. 3: Yes, you must pay taxes on your business income. If you have not created an LLC or a corporation, then your business income is added to your wage income to calculate your taxes. That is, if you made, say, $50,000 salary working for somebody else and $10,000 on your side business, then your total income is $60,000 and that's what you pay taxes on. The total amount you pay in income taxes will be the same regardless of whether 90% came from salary and 10% from the side business or the other way around. The rates are the same, it's just one total number. If the withholding on your regular paycheck is not enough to cover the total taxes that you will have to pay, then you are required by law to pay estimated taxes quarterly to make up the difference. If you don't, you will be required to pay penalties, so you don't want to skip on this. Basically you are supposed to be withholding from yourself and sending this in to the government. It's POSSIBLE that this won't be an issue. If you're used to getting a big refund, and the refund is more than what the tax on your side business will come to, then you might end up still getting a refund, just a smaller one. But you don't want to guess about this. Get the tax forms and figure out the numbers. I think -- and please don't rely on this, check on it -- that the law says that you don't pay a penalty if the total tax that was withheld from your paycheck plus the amount you paid in estimated payments is more than the tax you owed last year. So like lets say that this year -- just to make up some numbers -- your employer withheld $4,000 from your paychecks. At the end of the year you did your taxes and they came to $3,000, so you got a $1,000 refund. This year your employer again withholds $4,000 and you paid $0 in estimated payments. Your total tax on your salary plus your side business comes to $4,500. You owe $500, but you won't have to pay a penalty, because the $4,000 withheld is more than the $3,000 that you owed last year. But if next year you again don't make estimated payment, so you again have $4,000 withheld plus $0 estimated and then you owe $5,000 in taxes, you will have to pay a penalty, because your withholding was less than what you owed last year. To you had paid $500 in estimated payments, you'd be okay. You'd still owe $500, but you wouldn't owe a penalty, because your total payments were more than the previous year's liability. Clear as mud? Don't forget that you probably will also owe state income tax. If you have a local income tax, you'll owe that too. Scott-McP mentioned self-employment tax. You'll owe that, too. Note that self-employment tax is different from income tax. Self employment tax is just social security tax on self-employed people. You're probably used to seeing the 7-whatever-percent it is these days withheld from your paycheck. That's really only half your social security tax, the other half is not shown on your pay stub because it is not subtracted from your salary. If you're self-employed, you have to pay both halves, or about 15%. You file a form SE with your income taxes to declare it. 4: If you pay your quarterly estimated taxes, well the point of ""estimated"" taxes is that it's supposed to be close to the amount that you will actually owe next April 15. So if you get it at least close, then you shouldn't owe a lot of money in April. (I usually try to arrange my taxes so that I get a modest refund -- don't loan the government a lot of money, but don't owe anything April 15 either.) Once you take care of any business expenses and taxes, what you do with the rest of the money is up to you, right? Though if you're unsure of how to spend it, let me know and I'll send you the address of my kids' colleges and you can donate it to their tuition fund. I think this would be a very worthy and productive use of your money. :-) Back to #2. I just recently acquired a financial advisor. I can't say what a good process for finding one is. This guy is someone who goes to my church and who hijacked me after Bible study one day to make his sales pitch. But I did talk to him about his fees, and what he told me was this: If I have enough money in an investment account, then he gets a commission from the investment company for bringing the business to them, and that's the total compensation he gets from me. That commission comes out of the management fees they charge, and those management fees are in the same ballpark as the fees I was paying for private investment accounts, so basically he is not costing me anything. He's getting his money from the kickbacks. He said that if I had not had enough accumulated assets, he would have had to charge me an hourly fee. I didn't ask how much that was. Whew, hadn't meant to write such a long answer!" When you enter your expected gross income into the worksheet - just enter $360000 and leave everything else as is. That should give you the right numbers. Same for State (form DE-4). is it possible to file that single form aside from the rest of my return? Turbotax will generate all the forms necessary to file your return. I recommend you  access these forms and file them manually. According to the IRS in order to report capital gains and losses you need to fill out Form 8949 and summarize them on Form 1040 D. Add these two forms to the stack that turbotax generates. Add the total capital gains to line 13 of the Form 1040 which turbotax generated, and adjust the totals on the form accordingly. "I'm mostly guessing based on existing documentation, and have no direct experience, so take this with a pinch of salt. My best understanding is that you need to file Form 843. The instructions for the form say that it can be used to request: A refund or abatement of a penalty or addition to tax due to    reasonable cause or other reason (other than erroneous written    advice provided by the IRS) allowed under the law. The ""reasonable cause"" here is a good-faith confusion about what Line 79 of the form was referring to. In Form 843, the IRC Section Code you should enter is 6654 (estimated tax). For more, see the IRC Section 6654 (note, however, that if you already received a CP14 notice from the IRS, you should cross-check that this section code is listed on the notice under the part that covers the estimated tax penalty). If your request is accepted, the IRS should issue you Notice 746, item 17 Penalty Removed: You can get more general information about the tax collection process, and how to challenge it, from the pages linked from Understanding your CP14 Notice" Well you've got to think about the process, but first make sure the thing you want to pay for is actually a qualified dependent care expense.  Here is a list of eligible expenses from a national FSA administrator. This process will tie up your money for some amount of time.  Your deduction will come out like clockwork.  But there is a time-delay of potentially months between your deduction and receipt of a reimbursement. Dependent care plans are money-in money-out.  You can only file a reimbursement on funds that have actually been contributed, which is different than a medical FSA.  Additionally, you can only file a claim on expenses that have actually been incurred.  Dependent care FSA elections can be changed through the year on an as needed basis.  This would add an administrivia burden to the person running your payroll, and if there is a payroll vendor in place, likely an actual cost.  The administrator in this situation would likely be the company.  In the formalities of employee benefits there must always be a named administrator. If your employer currently offers no benefits you should press healthcare first.  Paying healthcare premiums pretax would likely save you more money and be less administration than this.  Additionally, if your employer is paying for or reimbursing you for your individual health insurance that's currently illegal under the ACA. IRS pub 521 has all the information you need. Expenses reimbursed. If you are reimbursed for your expenses and you   use the cash method of accounting, you can deduct your expenses either   in the year you paid them or in the year you received the   reimbursement. If you use the cash method of accounting, you can   choose to deduct the expenses in the year you are reimbursed even   though you paid the expenses in a different year. See Choosing when to   deduct, next. If you deduct your expenses and you receive the   reimbursement in a later year, you must include the reimbursement in   your income on Form 1040, line 21 This is not unusual. Anybody who moves near the end of the year can have this problem. The 39 week time test also can be an issue that span over 2 tax years. I would take the deduction for the expenses as soon a I could, and then count the income in the later year if they pay me back. IF they do so before April 15th, then I would put them on the same tax form to make things easier. Talk to a tax professional. The IRS really doesn't like the deduction, and it's a concept (like independent contractors) that is often not done properly. You need to, at a minimum, have records, including timestamped photographs, proving that: Remember, documentation is key, and must be filed and accessible for a number of years. Poor record keeping will cost you dearly, and the cost of keeping those records is something that you need to weigh against the benefit. I received a $2,000 bonus... Gross Income is income from whatever source derived, including (but not limited to) “compensation for services, including fees, commissions, fringe benefits, and similar items.”  Adjusted Gross Income is defined as gross income minus adjustments to income.  My question is, must I still report this money on my tax return and if so, how? Yes, and it would be on line 21 of your 1040 with supporting documentation. Are these legal fees deductible as an expense, and where would I list them? Yes, you would aggregate your deductible expenses and place these on your Schedule A. Instructions here. Good Luck. Edit: As Ben Miller pointed out in the comments, the deduction would be placed in either line 23 or 28 depending on the nature of the attorney (investment related or not). What happened is that they do not track (and report) your original cost basis for 1099-B purposes. That is because it is an RSU. Instead, they just reported gross proceeds ($5200) and $0 for everything else. On your Schedule D you adjust the basis to the correct one, and as a comment you add that it was reported on W2 of the previous year. You then report the correct $1200 gain. You keep the documentation you have to back this up in case of questions (which shouldn't happen, since it will match what was indeed reported on your W2). "Can I use the foreign earned income exclusion in my situation? Only partially, since the days you spent in the US should be excluded. You'll have to prorate your exclusion limit, and only apply it to the income earned while not in the US. If not, how should I go about this to avoid being doubly taxed for   2014? The amounts you cannot exclude are taxable in the US, and you can use a portion of your Norwegian tax to offset the US tax liability. Use form 1116 for that. Form 1116 with form 2555 on the same return will require some arithmetic exercises, but there are worksheets for that in the instructions. In addition, US-Norwegian treaty may come into play, so check that out. It may help you reduce the tax liability in the US or claim credit on the US taxes in Norway. It seems that Norway has a bilateral tax treaty with the US, that, if   I'm reading it correctly, seems to indicate that ""visiting researchers   to universities"" (which really seems like I would qualify as) should   not be taxed by either country for the duration of their stay. The relevant portion of the treaty is Article 16. Article 16(2)(b) allows you $5000 exemption for up to a year stay in the US for your salary from the Norwegian school. You will still be taxed in Norway. To claim the treaty benefit you need to attach form 8833 to your tax return, and deduct the appropriate amount on line 21 of your form 1040. However, since you're a US citizen, that article doesn't apply to you (See the ""savings clause"" in the Article 22). I didn't even give a thought to state taxes; those should only apply   to income sourced from the state I lived in, right (AKA $0)? I don't know what State you were in, so hard to say, but yes - the State you were in is the one to tax you. Note that the tax treaty between Norway and the US is between Norway and the Federal government, and doesn't apply to States. So the income you earned while in the US will be taxable by the State you were at, and you'll need to file a ""non-resident"" return there (if that State has income taxes - not all do)." "You will be filing the exact same form you've been filing until now (I hope...) which is called form 1040. Attached to it, you'll add a ""Schedule C"" form and ""Schedule SE"" form. Keep in mind the potential effect of the tax and totalization treaties the US has with the UK which may affect your filings. I suggest you talk to a licensed EA/CPA who works with expats in the UK and is familiar with all the issues. There are several prominent offices you can find by Googling." If this is something you plan to continue doing it would make sense to create it as it's own business entity and then to get non-profit status eg: 501c3.   Otherwise I'm pretty sure you have to think of it as YOU receiving the money as a sole proprietor - and file a couple more tax forms at the end of the year. I think it's a Schedule C.  So essentially if you bring in $10,000, then you spend that $10,000 as legit business expenses for your venture your schedule C would show no profit and wouldn't pay taxes on it. BUT, you do have to file that form. Operating this way could have legal implications should something happen and you get sued. Having the proper business entity setup could help in that situation. There is a tax advantage only for medical expenses exceeding 10% of your adjusted gross income (7.5% if over age 65).  This limit means only a very few people can take advantage of the deduction. The expenses would be entered on Schedule A (itemized deductions) of form 1040. You don't have to send in the supporting documentation, but you have to keep it in your records to present if audited. Yes, a copay qualifies as an expense, but needs supporting documentation. In a nutshell, throwing your taxable income in the trash does not remove it from your taxable income; you still have to report in your tax filing, and pay taxes as needed. Especially as you could at any time request your employer to write you a replacement check. I would expect them to start charging a fee for reprinting if you really annoy them by doing it dozens of times. If you want to avoid taxes on it, donate it to a deductible 501(c)3 organization; then it becomes neutral to your taxes.
