What is a W-8 form, and how should I fill it in?
"The IRS W-8BEN form (PDF link), titled ""Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding"", certifies that you are not an American for tax purposes, so they won't withhold tax on your U.S. income. You're also to use W-8BEN to identify your country of residence and corresponding tax identification number for tax treaty purposes.  For instance, if you live in the U.K., which has a tax treaty with the U.S., your W-8BEN would indicate to the U.S. that you are not an American, and that your U.S. income is to be taxed by the U.K. instead of tax withheld in the U.S. I've filled in that form a couple of times when opening stock trading accounts here in Canada.  It was requested by the broker because in all likelihood I'd end up purchasing U.S.-listed stocks that would pay dividends.  The W-8BEN is needed in order to reduce the U.S. withholding taxes on those dividends. So I would say that the ad revenue provider is requesting you file one so they don't need to withhold full U.S. taxes on your ad revenue. Detailed instructions on the W-8BEN form are also available from the IRS: Instruction W-8BEN (PDF link). On the subject of ad revenue, Google also has some information about W8-BEN: Why can't I submit a W8-BEN form as an individual?"
There are many different types of 1099 forms. Since you are comparing it to a W-2, I'm assuming you are talking about a 1099-MISC form.  Independent contractor income If you are a worker earning a salary or wage, your employer reports   your annual earnings at year-end on Form W-2. However, if you are an   independent contractor or self-employed you will receive a Form   1099-MISC from each client that pays you at least $600 during the tax   year. For example, if you are a freelance writer, consultant or   artist, you hire yourself out to individuals or companies on a   contract basis. The income you receive from each job you take should   be reported to you on Form 1099-MISC. When you prepare your tax   return, the IRS requires you to report all of this income and pay   income tax on it. So even if you receive a 1099-MISC form, you are required to pay taxes on it. As a resident of New York State you will, in addition to the Federal income tax handled by the IRS, be responsible for state and local income taxes. For New York the state tax forms are also used to determine your New York city tax. If HR was either not aware of the local tax requirement for New York or you filled out the New York State version of the W-4 incorrectly you may have had too little tax withheld for New York state. The refund from the IRS is not dependent on the refund/owe status for state and local taxes. It is possible that your state taxes are fine but that you owe taxes to the city. That tax you owe to the city will reduce the refund from the state and may require you to pay money to New York. Of course if you do itemize, what you pay to the state and city may result in deductions on your federal form. If you owe back taxes to the state or local government this could result in the IRS seizing a federal refund, but that doesn't happen right away. The 401K match has limits, but it is not taxable until you withdraw the money from the account. You can think of it as an initial lump of interest or gain.  When you leave the company you are allowed to keep it, if you are vested. You can then roll it over into a IRA, or another 401K. When you withdraw money in retirement you will pay taxes on the match and all the gains from the match. Taxes on what you contribute will depend on if it was pre-tax or post-tax, or if it was deposited into a Roth IRA. The amount you deposit pretax is noted on the W-2, which you attach to the 1040 form. The company match does not appear anywhere on the w-2 or 1040. It should show on your 401-K statements. Those statements should also tell you how much of the match has been vested. You need an accountant who will be on your side. Not someone who will help you just fill in forms correctly . Too many play it by the book. Expense as much as you can. Your balance sheet should be a list of what you have (assets), who owes you money and who you owe, and how much cash you have. Good luck! I think the IRS doc you want is http://www.irs.gov/publications/p550/ch04.html#en_US_2010_publink100010601 I believe the answers are: There are a few methods you can use to estimate your taxes. On the results screen, the app will show you your estimated tax burden, your estimated withholding for the year, and your estimated overpayment/refund or shortfall/tax due.  It may also have recommendations for you on how to adjust your W-4 (although, this late in the year, I think it only tells you to come back next year to reevaluate).   Your state might also have income tax, and if you are curious about that, you can find the state tax form and estimate your state income tax as well. My guess is that you will be getting a refund this year, as you have only worked half of the year.  But that is only a guess. 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. "Depending on the nature of the expenses, you will enter them under Deductions, on lines 9 through 20. Did you rent an office? Add the rental expense to line 13. Fee for a business license? Line 14. Everything else that doesn't fall into any specific category goes on line 20 (You'll need to attach a small statement that breaks out the expense categories, e.g. office supplies, phone, legal fees, etc.)  Expenses that are entered in the Income section are costs directly related to sales, such as merchant fees that you pay to a bank if you take payments by credit card. Since you said the partnership has ""zero money coming in,"" I assume that it currently has no revenues, so all the fields in the Income section would be zero."
