If I have no exemptions or deductions, just a simple paycheck, do I HAVE to file taxes?
"As a Canadian resident, the simple answer to your question is ""yes"" Having worked as a tax auditor and as a Certified Financial Planner, you are required to file an income tax return because you have taxable employment income. All the employer is doing is deducting it at source and remitting it on your behalf. That does not alleviate your need to file. In fact, if you don't file you will be subject to a no filing penalty. The one aspect you are missing is that taxpayers may be entitled to tax credits that may result in a refund to you depending on your personal situation (e.g spousal or minor dependents). I hope this helps." 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. Yes, you have to file a tax return in Canada.  Non residents that have earned employment income in Canada are required to file a Canadian personal income tax return. Usually, your employer will have deducted sufficient taxes from your pay-cheques, resulting in a tax refund upon filing your Canadian tax return. You will also receive a tax credit on your US tax return for taxes paid in Canada. In many cases, you are required to file your taxes by law even if you won't owe. If it's anything like in the US, it's quite possible your employer is not taking the right amount and you may owe more or may even be in line for a return. http://www.usatax.ca/Pages/filing_requirement_taxes_canada.html If you took advantage of options like a home buyers plan (HBP) you definitely need to file since you must designate how much of the plan to repay.  Your employer does not know about what you do with your money so cannot take this into account for the withheld taxes.  If you do not report repayment of the HBP it will be treated as a withdrawal from your RRSP i.e. additional income for that tax year. You are not required to file a tax return in Canada if you have no taxable income. If you do not file a return you may be requested to by Canada Revenue Agency, and then you'll need to file one. There are hundreds of thousands of Canadian residents who do not file tax returns. The Minister who overlooks the CRA may assess any amount of taxes on any resident whether they file a return or not. There are penalties for failing to file a return or filing late. The penalties are based on a percentage of the taxes owed. If you owe no taxes, then the penalties are meaningless.
"There's no ""183 days"" rule. As a US citizen you must pay taxes on all your income, where you live is irrelevant." "You file taxes as usual. W2 is a form given to you, you don't need to fill it. Similarly, 1099. Both report moneys paid to you by your employers. W2 is for actual employer (the one where you're on the payroll), 1099 is for contractors (where you invoice the entity you provide services to and get paid per contract). You need to look at form 1040 and its instructions as to how exactly to fill it. That would be the annual tax return. It has various schedules (A, B, C, D, E, F, H, etc) which you should familiarize yourself with, and various additional forms that you attach to it. If you're self employed, you're expected  to make quarterly estimate payments, but if you're a salaried employee you can instruct your employer to withhold the amounts you expect to owe for taxes from your salary, instead. If you're using a tax preparation software (like TurboTax or TaxAct), it will ""interview"" you to get all the needed information and provide you with the forms filled accordingly. Alternatively you can pay someone to prepare the tax return for you." I filed all my tax returns when I was abroad so they know how much I   made (just not how much I saved). I smell problems here. If you were compliant wrt to your filings, you must have filed FBAR forms and form 8938. Even if you were below the threshold for form 8938, you will probably be above it when you move back to the US - the threshold for people living in the US is much lower. Do I still need to declare it, even though I might not intend to use   this money to help my kids through college? I believe so. Here's what they want: Nothing there suggests that it is only limited to the accounts in the US or to the money you intend to use to help your kids through college. If you're under audit - you should get a proper representation. I.e.: EA or CPA licensed in California and experienced with the FTB audit representation. There's a penalty on failure to file form 1099, but it is with the IRS, not the FTB. If I remember correctly, it's something like $50 or $100 per instance. Technically they can disqualify deductions claiming you paid under the table and no taxes were paid on the other side, however I doubt they'd do it in a case of simple omission of filing 1099 forms. Check with your licensed tax adviser. Keep in mind that for the IRS 2011 is now closed, since the 3-year statute of limitations has passed. For California the statute is 4 years, and you're almost at the end of it. However since you're already under audit they may ask you to agree to extend it. "In a word, no. If your income is high enough to have to file a return, you have to file a return. My accountant has a nice mindset for making it more palatable. I'll paraphrase: ""Our tax system is ludicrously complicated. As a result, it is your duty as an American to seek out and take advantage of every deduction and credit available to you. If our politicians and leaders put it into the tax code, use it to your advantage."" A friend of mine got a free golf cart that way. It was a crazy combination of credits and loopholes for electric vehicles. That loophole has been closed, and some would say it's a great example of him exercising his patriotic duty." Not correct. First - when you say they don't tax the reimbursement, they are classifying it in a way that makes it taxable to you (just not withholding tax at that time).  In effect, they are under-withholding, if these reimbursement are high enough, you'll have not just a tax bill, but penalties for not paying enough all year.  My reimbursements do not produce any kind of pay stub, they are a direct deposit, and are not added to my income, not as they occur, nor at year end on W2.  Have you asked them why they handle it this way? It's wrong, and it's costing you. Your employer pays the expected (but estimated) taxes for you. So the chances are you don't own more; but that might be different if you have other sources of income that he doesn't know about (interest on savings or a side-job or whatever). Also, you could have deductions that reduce the taxes you owe, which he again doesn't know, so you overpay. If you don't file, you don't get them back. Most tax software companies offer free usage of their tool for standard filings, and you can use it to find out your tax situation, and then buy the tool only when you want to file. If you use one of those, you can type in all your data, and depending on the result, decide to buy it and file right away. Note that if it turns out you owe taxes, you must file (and pay), but of course you can do it manually instead of buying the tool. If it turns out you get money back, it is your decision to file - you probably don't care for a small amount, but if you get 1000 $ back, you might want to file - again, buying the software of doing it manually. One significant reason it makes sense for filing to be the default is home ownership rates.  I think far more so than investment income, Americans own homes: as there is a significant mortgage interest deduction, between that and investments a large number of Americans would have to file (about a third of Americans get the mortgage interest tax deduction, and a large chunk of the richest don't qualify but would have to file for investments anyway). We also have a very complicated tax code, with nearly everyone getting some kind of deduction.  Earned Income Tax Credit for the working poor (folks making, say, $30k for a family of 4 with a full-time job get several thousand dollars in refundable credits, for example), the Student Loan interest deduction, the above mortgage deduction, almost everyone gets something. Finally, your employer may not know about your family situation.  As we have tax credits and deductions for families based on number of children, for example, it's possible your employer doesn't know about those (if you don't get health insurance on their behalf, they may well not know).  Start reporting things like that separately... and you end up with about as much work as filing is now. "Does he need to file a tax return in this situation? Will the IRS be concerned that he did not file even if he received a 1099? No. However, if you don't file the IRS may come back asking why, or ""make up"" a return for you assuming that the whole amount on the 1099-MISC is your net earnings. So in the end, I suspect you'll end up filing even though you don't have to, just to prove that you don't have to. Bottom line - if you have 1099 income (or any other income reported to the IRS that brings you over the filing threshold), file a return." "I'm assuming that you're in the US.  In that case, the answer is that it depends on how your company set up its reimbursement plan.  The IRS recognizes ""accountable"" and ""nonaccountable"" plans.  Accountable plans have to meet certain requirements.  Anything else is nonaccountable.  If you are reimbursed according to an accountable plan, this is not income and should not be reported to the IRS at all.  If you are reimbursed under a nonaccountable plan, then this is income but you might be able to get a deduction on your tax return if you itemize. Most established companies have accountable plans for normal business expenses. More detail from IRS: http://www.tax.gov/TaxabilityCertainFringeBenefits/pdf/Accountable_v_Nonaccountable_Plans_Methods_of_Reimbursing_Employees_for_Expense.pdf" Companies in the US will take care of paying a portion of your required income tax on your behalf based on some paperwork you fill out when starting work.  However, it is up to you as an individual to submit an income tax return.  This is used to ensure that you did not end up under or overpaying based on what your company did on your behalf and any other circumstances that may impact your actual tax owed. In my experience, the process is similar in Europe.  I think anyone who has a family, a house or investments in Europe would need to file an income tax return as that is when things start to get complex. "There are many people who have deductions far above the standard deduction, but still don't itemize. That's their option even though it comes at a cost. It may be foolish, but it's not illegal.  If @littleadv citation is correct, the 'under penalty of perjury' type issue, what of those filers who file a Schedule A but purposely leave off their donations? I've seen many people discuss charity, and write that they do not want to benefit in any way from their donation, yet, still Schedule A their mortgage and property tax. Their returns are therefore fraudulent.  I am curious to find a situation in which the taxpayer benefits from such a purposeful oversight, or, better still, a cited case where they were charged with doing so. I've offered advice on filings return that wasn't ""truthful"". When you own a stock and cannot find cost basis, there are times that you might realize the basis is so low that just entering zero will cost you less than $100 in extra tax. You are not truthful, of course, but this kind of false statement isn't going to lead to any issue. If it gets noticed within an audit, no agent is going to give it more than a moment of time and perhaps suggest, ""you didn't even know the year it was bought?"" but there would be no consequence.  My answer is for personal returns, I'm sure for business, accuracy to the dollar is actually important." It would be quite the trick for (a) the government to run all year and get all its revenue in April when taxes are due and (b) for people to actually save the right amount to be able to cut that check each year. W2 employers withhold the estimated federal and state taxes along with the payroll (social security) tax from each paycheck. Since the employer doesn't know how many kids you have, or how much mortgage interest, etc you will take deductions for, you can submit a W4 form to adjust withholdings.   The annual Form 1040 in April is to reconcile exact numbers, some people get a refund of some of what they paid in, others owe some money.  If one is self-employed, they are required to pay quarterly estimated taxes. And they, too, reconcile exact numbers in April. Legally, do I have anything to worry about from having an incorrectly filed W-4? What you did wasn't criminal. When you submitted the form it was correct. Unfortunately as your situation changed you didn't adjust the form, that mistake does have consequences. Is there anything within my rights I can do to get the company to take   responsibility for their role in this situation, or is it basically my   fault? It is basically your fault. The company needs a w-4 for each employee. They will use that W-4 for every paycheck until the government changes the regulation, or your employment ends, or you submit a new form. Topic 753 - Form W-4 – Employee's Withholding Allowance Certificate If an employee qualifies, he or she can also use Form W-4 (PDF) to   tell you not to deduct any federal income tax from his or her wages.   To qualify for this exempt status, the employee must have had no tax   liability for the previous year and must expect to have no tax   liability for the current year. However, if the employee can be   claimed as a dependent on a parent's or another person's tax return,   additional limitations may apply; refer to the instructions for Form   W-4. A Form W-4 claiming exemption from withholding is valid for   only the calendar year in which it is filed with the employer. To   continue to be exempt from withholding in the next year, an employee   must give you a new Form W-4 claiming exempt status by February 15 of   that year. If the employee does not give you a new Form W-4,   withhold tax as if he or she is single, with no withholding   allowances. However, if you have an earlier Form W-4 (not claiming   exempt status) for this employee that is valid, withhold as you did   before. (I highlighted the key part) Because you were claiming exempt they should have required you to update that form each year. In your case that may not have applied because of the timing of the events. When do you submit a new form? Anytime your situation changes. Sometimes the change is done to adjust withholding to modify the amount of a refund. Other times failure to update the form can lead to bigger complication: when your marital status changes, or the number of dependents changes. In these situations you could have a significant amount of under-withheld, which could lead to a fine later on. As a side note this is even more true for the state version of a W-4. Having a whole years worth of income tax withholding done for the wrong state will at a minimum require you to file in multiple states, it could also result in a big surprise if the forgotten state has higher tax rate. Will my (now former) employee be responsible for paying their portion of the taxes that were not withheld during the 9 months I was   full-time, tax Exempt? For federal and state income taxes they are just a conduit. They take the money from your paycheck, and periodically send it to the IRS and the state capital. Unless you could show that the pay stubs said taxes were being withheld, but the w-2 said otherwise; they have no role in judging the appropriateness of your W-4 with one exception. Finally, and I am not too hopeful on this one, but is there anything I   can do to ease this tax burden? I understand that the IRS is owed no   matter what. You have one way it might workout. For many taxpayers who have a large increase in pay from one year to the next, they can take advantage of a safe-harbor in the tax law. If they had withheld as much money in 2015 as they paid in 2014, they have reached the safe-harbor. They avoid the penalty for under withholding. Note that 2014 number is not what you paid on tax day or what was refunded, but all your income taxes for the entire year. Because in your case your taxes for the year 2014 were ZERO, that might mean that you automatically reach the safe-harbor for 2015. That makes sense because one of the key requirements of claiming exempt is that you had no liability the year before. It won't save you from paying what you owe but it can help avoid a penalty. Lessons "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."
