When filing for an NOL, do you have to file the amended previous years' returns after the NOL return?
Your CPA doesn't need to file anything, so don't worry about him being sidetracked. You are the one doing the filing. Since the amended returns have to be filed on paper, you'll actually go and mail a package to the IRS (each return in a separate envelope). The reason the CPA suggests to file the amended returns after the current one, is to ensure the NOL is registered in the system before the amended returns are processed. The IRS doesn't have to automatically accept the amended returns, and if there's no NOL on the current year they may just bounce the amended returns back to you. Keep in mind that since you haven't filed your return by the due date (including extensions), you're now unable to forego the carry-back. I don't know if you discussed this with your CPA, but you're allowed, if you chose so, to not apply the NOL to prior years, and instead to apply it forward for the next 20 years (or until it runs out). Depending on your income pattern, that might have been something you could have considered, but you can only chose this if you file a statement before the due date (with extensions), which is now passed.
While you are required to do so as others have said, it's actually in your interest to do so. In a recent article at GlobeInvestor, Tim Cestnick discusses the benefits of filing tax returns for teens. This situation may or may not apply to you but the message is the same. The main benefits are (1) create RRSP contribution room and (2) be eligible for GST/HST credits and other possible one-shot credits (think oil royalty surplus cheques in Alberta). Excerpt: You see, when Lincoln was 14, he filed a tax return and reported $2,000 of income that year. He paid no tax thanks to the basic personal tax credit, but he created $360 of RRSP contribution room that year. Beginning in 2003, Lincoln started working part-time in his father's business. His father agreed to pay him $6,000 each summer to work in the business, to help save money for university. Lincoln didn't pay any tax on the money he earned in those summers because his basic personal tax credit was always higher than his earnings. In addition, Lincoln added to his RRSP contribution room simply by filing a tax return each year. There are ways to avoid having federal income taxes withheld:  In order to avoid withholding altogether, you’ll have to fall into   both of the following categories: you have no tax liability this year   and you had no tax liability in the previous tax season, so all of the   federal income tax you paid was given back to you. Generally, you can   say you have no tax liability when you’re not required to file an   income tax return or you owe zero taxes. You may also be able to claim   an exemption if your earned income for the year is extremely low   ($1,050 or less). If those conditions apply to you, you can write “exempt” in line 7.   Keep in mind that the exemption only eliminates your federal income   taxes, not your Medicare or Social Security. If your parents use an accountant to prepare their taxes, I'm sure he/she would be able to give you a solid answer on how to fill it out. "Do I understand correctly, that we still can file as ""Married filing   jointly"", just add Schedule C and Schedule SE for her? Yes. Business registration information letter she got once registered   mentions that her due date for filing tax return is January 31, 2016.   Does this prevent us from filing jointly (as far as I understand, I   can't file my income before that date)? IRS sends no such letters. IRS also doesn't require any registration. Be careful, you might be a victim to a phishing attack here. In any case, sole proprietor files a regular individual tax return with the regular April 15th deadline. Do I understand correctly that we do not qualify as ""Family   partnership"" (I do not participate in her business in any way other   than giving her money for initial tools/materials purchase)? Yes. Do I understand correctly that she did not have to do regular   estimated tax payments as business was not expected to generate income   this year? You're asking or saying? How would we know what she expected? In any case, you can use your withholding (adjust the W4) to compensate." "In the U.S., Form 1040 is known as the tax return.  This is the form that is filed annually to calculate your tax due for the year, and you either claim a refund if you have overpaid your taxes or send in a payment if you have underpaid.  The form is generally due on April 15 each year, but this year the due date is April 18, 2016. When it comes to filing your taxes, there are two questions you need to ask yourself: ""Am I required to file?"" and ""Should I file?"" Am I required to file? The 1040 instructions has a section called ""Do I have to file?"" with several charts that determine if you are legally required to file.  It depends on your status and your gross income.  If you are single, under 65, and not a dependent on someone else's return, you are not required to file if your 2015 income was less than $10,300.  If you will be claimed as a dependent on someone else's return, however, you must file if your earned income (from work) was over $6300, or your unearned income (from investments) was over $1050, or your gross (total) income was more than the larger of either $1050 or your earned income + $350.  See the instructions for more details. Should I file? Even if you find that you are not required to file, it may be beneficial to you to file anyway.  There are two main reasons you might do this: If you have had income where tax has been taken out, you may have overpaid the tax.  Filing the tax return will allow you to get a refund of the amount that you overpaid. As a student, you may be eligible for student tax credits that can get you a refund even if you did not pay any tax during the year. How to file For low income tax payers, the IRS has a program called Free File that provides free filing software options." "The refund may offset your liability for the next year, especially if you are a Schedule ""C"" filer.  By having your refund applied to the coming year's taxes you are building a 'protection' against a potentially high liability if you were planning to sell a building that was a commercial building and would have Capital Gains. Or you sold stock at a profit that would also put you in the Capital Gain area.  You won a large sum in a lottery, the refund could cushion a bit of the tax. In short, if you think you will have a tax liability in the current year then on the tax return you are filing for the year that just past, it may be to your benefit to apply the refund.  If you owe money  from a prior year, the refund will not be sent to you so you will not be able to roll it forward.    One specific example is you did qualify in the prior year for the ACA.  If in the year you are currently in- before you file your taxes-- you realize that you will have to pay at the end of the current year, then assigning your refund will pay part or all of the liability. Keep in mind that the 'tax' imposed due to ACA is only collected from your refunds.  If you keep having a liability to pay  or have no refunds due to you, the liability is not collected from you." I'm not sure how this gets entered in TurboTax, but this income from the company should be included in the Schedule C (or C-EZ) Line 1 Gross Receipts total, along with all of your 1099-MISC income from your business and any other income that your business took in. You don't need a 1099 from them, and the IRS doesn't care (at least from your perspective) if you got a 1099 or not; in fact, they probably expect you to have some non-1099 income.  We don't know why the company chose not to issue 1099 forms, but luckily it isn't your concern. You can fill out your tax return properly without it.  Note: This answer assumes that you didn't have any tax withheld from your checks from this company. If you did have tax withheld, you'll need to insist on a 1099 to show that. You decide on a cost bases attribution yourself, per transaction (except for averaging for mutual funds, which if I remember correctly applies to all the positions). It is not a decision your broker makes. Broker only needs to know what you've decided to report it to the IRS on 1099, but if the broker reported wrong basis (because you didn't update your account settings properly, or for whatever else reason) you can always correct it on form 8949 (columns f/g). "Read up on filing an ""amended tax return"".  Essentially you'll fill out the entire return as it should have been originally, then fill out form 1040X stating what has changed (and pay the additional tax due if needed).   According to TurboTax's website, they have partnered with Sprintax for non-resident tax prep.  I am not vouching for the service; just offering it as information."
