Form 1040 - where to place my stipend?
If you're correct that it's not taxable because it's non-taxable reimbursement (which is supported by your W-2), then it should not go on your 1040 at all.  If it is taxable, then it really should have appeared on your W-2 and would probably end up on Line 7 of your Form 1040. "Some of the 45,000 might be taxable. The question is how was the stipend determined. Was it based on the days away? The mile driven? The cities you worked in? The IRS has guidelines regarding what is taxable in  IRS Pub 15 Per diem or other fixed allowance.  You may reimburse your employees by travel days, miles, or some other   fixed allowance under the applicable revenue procedure. In these   cases, your employee is considered to have accounted to you if your   reimbursement doesn't exceed rates established by the Federal   Government. The 2015 standard mileage rate for auto expenses was 57.5   cents per mile. The rate for 2016 is 54 cents per mile. The government per diem rates for meals and lodging in the continental   United States can be found by visiting the U.S. General Services   Administration website at www.GSA.gov and entering ""per diem rates"" in   the search box. Other than the amount of these expenses, your   employees' business expenses must be substantiated (for example, the   business purpose of the travel or the number of business miles   driven). For information on substantiation methods, see Pub. 463. If the per diem or allowance paid exceeds the amounts substantiated,   you must report the excess amount as wages. This excess amount is   subject to income tax with-holding and payment of social security,   Medicare, and FUTA taxes. Show the amount equal to the substantiated   amount (for example, the nontaxable portion) in box 12 of Form W-2   using code “L"""
According to pages 6 & 7 of the instructions for form 1040 in 2009 AMT was only temporarily patched for the year. Congress can't politically afford to drastically cut AMT exemptions by 30 to 40%, and may even retroactively change it, if it isn't passed by the end of the year (despite the constitution forbidding ex post facto laws) : What’s New for 2009 ...    Alternative minimum tax (AMT) exemption amount increased. The AMT exemption amount has increased to $46,700 ($70,950 if married filing jointly or a qualifying widow(er); $35,475 if married filing separately)... What’s New for 2010 ...    Alternative minimum tax (AMT) exemption amount. The AMT exemption amount is scheduled to decrease to $33,750 ($45,000 if married filing jointly or a qualifying widow(er); $22,500 if married filing separately). So, if you are married, and several regular tax deductions push your income below the AMT exemption amount of $45,000, it's quite possible you would be required to pay AMT, even if you didn't last year. There is a work sheet for AMT in the instructions for line 43, but the IRS also provides an AMT calculator. According to page 146 (E-8) of the instructions for form 1040 AMT is paid as: the smallest amount you are allowed to report as your taxable income (Form 1040, line 43). It is also the smallest amount you are allowed to report as your alternative minimum taxable income   (AMTI) on Form 6251, line 29. If the [AMT calculation] is larger than your taxable income would otherwise be, enter the amount from column (c) on Form 1040, line 43 [or ...] Form 6251, line 29.  As always, congress finds ways to further complicate things by making a few credits and losses deductible against the absolute minimum you're expected to pay taxes on, making the AMT a misnomer. Through your question and then clarification through the comments, it looks like you have a U.S. LLC with at least two members.  If you did not elect some other tax treatment, your LLC will be treated as a partnership by the IRS.  The partnership should file a tax return on Form 1065.  Then each partner will get a Schedule K-1 from the partnership, which the partner should use to include their respective shares of the partnership income and expenses on their personal Forms 1040. You can also elect to be taxed as an S-Corp or a C-Corp instead of a partnership, but that requires you to file a form explicitly making such election.  If you go S-Corp, then you will file a different form for the company, but the procedure is roughly the same - Income gets passed through to the owners via a Schedule K-1.  If you go C-Corp, then the owners will pay no tax on their own Form 1040, but the C-Corp itself will pay income tax. As far as whether you should try to spend the money as business expense to avoid paying extra tax - That's highly dependent on your specific situation.  I'd think you'd want to get tailored advice for that. Yes, you can send in a 2012 1040-ES form with a check to cover your tax liability. However, you will likely have to pay penalties for not paying tax in timely fashion as well as interest on the late payment. You can have the IRS figure the penalty and bill you for it, or you can complete Form 2210 (on which these  matters are figured out) yourself and file it with your Form 1040. The long version of Form 2210 often results in the smallest extra amount due but is considerably more time-consuming to complete correctly. Alternatively, if you or your wife have one or more paychecks coming before the end of 2012, it might be possible to file a new W-4 form with the HR Department with a request to withhold additional amounts as Federal income tax. I say might because if the last paycheck of the year will be issued in just a few days' time, it might already have been sent for processing, and HR might tell you it is too late. But, depending on the take-home pay, it might be possible to have the entire $2000 withheld as additional income tax instead of sending in a 1040-ES. The advantage of doing it through withholding is that you are allowed to treat the entire withholding for 2012 as satisfying the timely filing requirements. So, no penalty for late payment even though you had a much bigger chunk withheld in December, and no interest due either.  If you do use this approach, remember that Form W-4 applies until it is replaced with another, and so  HR will continue to withhold the extra amount on your January paychecks as well.  So, file a new W-4 in January to get back to normal withholding. (Fix the extra exemption too so the problem does not recur in 2013). "What you should do is called ""re-characterization"". See the instructions for form 8606 for details (that is also the form to use to report the incident). See example 3: You made a contribution to a Roth IRA and later recharacterized part   or all of it to a traditional IRA. Report the nondeductible   traditional IRA portion, if any, on Form 8606, Part I. If you did not   recharacterize the entire contribution, do not report the remaining   Roth IRA portion of the contribution on Form 8606. Attach a statement   to your return explaining the recharacterization. If the   recharacterization occurred in 2012, include the amount transferred   from the Roth IRA on Form 1040, line 15a; Form 1040A, line 11a; or   Form 1040NR, line 16a. If the recharacterization occurred in 2013,   report the amount transferred only in the attached statement, and not   on your 2012 or 2013 tax return. You re-characterize it back to traditional IRA contribution, which will not be deductible. You then convert it back to a Roth IRA. Basically you end up at exactly the same place, except that if you already had some gains on that amount - you'll have to pay tax on them now (for the conversion, since because of the re-characterization, it will now be gains in a traditional IRA). You should of course contact your broker to do the re characterization (reassigning of the amount and its gains from a Roth IRA account to a traditional IRA account)." I received the same error message and was able to resolve the issue by checking line 7 of my 1040 form( where the total income from wages,tips,etc as stated on the W-2) and deleting the quantity I had placed in either of the gray boxes. If you wrote the sum of your income on the doted lines in either of the gray areas of line 7 (or other such areas on other lines) then this error might result. The grey areas as I understand it, are reserved for certain descriptors which are defined in the 1040 instructions included with the free file fillable form 1040. A stipend received for the specific purposes of studies is not taxable. It is not clear from your question as to whether there are any strings attached to the money you receive. If its not for specific purpose, then its taxable as income and tax need to be paid accordingly. Please consult a CA and he can go through the specifics of your case. You have interpreted the instructions correctly. The issue with two jobs at the same time, is that that second job will be taxed at the highest rate; but the second employer has no idea what the other position is paying you.  If you make enough to be in the 15% tax bracket for your main job that means: some of the money from each paycheck is  taxed zero; some is taxed at 10% and the last dollars are taxed at 15%. But the second job should withhold for taxes to cover all the income at 15%. To avoid problems you should look at the tax form you are filling out this year. Look at the total tax you paid. Not the refund or the amount you owed when you filed but your total tax paid. The government allows a safe harbor if you make sure that in 2016 you have the same amount withheld this calendar year. If that isn't enough, you will owe money in April 2017, but you will not have to pay a penalty. After you have a couple of paycheck from your main employer, check to see that if you work the rest of the year at that same rate that the federal withholding will make the safe harbor. If you will make it,  you don't have to worry about the penalty. If you will fall short, adjust the w-4 accordingly. This is a frequent problem for anyone with a large amount of deductions, whether it is student loan interest, home mortgage interest, charitable contributions, or anything else.  As an employee getting your tax withheld from your check, your options to reduce the amount withheld are limited. The HR department has no control over how much they withhold; the amount is calculated using a standard formula based on the number of exemptions you tell them.  The number of exemptions you claim on your W-4 form does not have to match reality. If you currently have 1 exemption claimed, ask them what the withholding would be if you claimed 4 exemptions. If that's not enough, go higher. As long as you are not withholding so little that you have a large tax bill at the end of the year, you are fine.  Of course, when you do your taxes, you need to have the correct number of exemptions claimed on your 1040, but this number does not need to match your W-4.
