Do I owe taxes if my deductions are higher than my income?
"There's one factor the previous posters apparently missed here: You say ""self-employment tax""--in other words, at least some of that $16k is from self employment.  In a normal employment situation the FICA tax is taken out of your paycheck, it's normally spot on and generally doesn't show up on your tax return. However, for the self-employed it's another matter.  You pay the whole 15.3% from the first dollar and this does show up on your tax return.  If it's all self employment money you would have about $2.5k in tax from this." No, it's not possible. Even if you had no deduction or credits, your federal tax on $16,604 would be: $9075 @ 10% = $907.50 +  $7529 @ 15% = $1129.35 = $2036.85 That assumes you are filing as single. There must be more to the story.  Typo in your income numbers?  Also, what do you mean by a self-employment tax deduction? Maybe update your question to include a breakdown of everything you entered? Edit: As noted in Loren's answer, it seems that it is indeed possible in at least one case (self-employment taxes). I'm going to echo Phil and say that you should add more information. That being said, I think it is possible for you to owe the government that much. If you received a federal health insurance subsidy and live in a state that didn't expand medicaid, you could have received a subsidy through out the year that you did not end up qualifying for. It appears you are outside the medicaid limit of 133% of the poverty level($11,670) or $15,521. If you received a subsidy of $275 a month from the marketplace, you would have received $3300 worth of aid from the government that you don't qualify for. Now they are expecting you to pay it back. As a CPA I can say, without a doubt, you do not owe any federal income tax. However, assuming all of you income was from your business and therefore subject to self-employment tax and you had no healthcare coverage, you would owe: $2,523 in Self-Employment Tax    645 in Healthcare Penalty $3,168 Total Amount You Should Owe. Assuming you have given us the right numbers, $3,300 sounds too high. "In your case, I believe the answer is that you don't owe any taxes, if your deductions exceed your income. There is something called the Alternate Minimum Tax to catch ""rich"" people, who claim ""too many"" deductions. Basically, it taxes their ""gross"" income at a lower rate, but allows them no deductions if they make $175,000 or more. You are not in that tax ""bracket."""
FICA taxes are separate from federal and state income taxes. As a sole proprietor you owe all of those.  Additionally, there is a difference with FICA when you are employed vs. self employed.  Typically FICA taxes are actually split between the employer and the employee, so you pay half, they pay half. But when you're self employed, you pay both halves. This is what is commonly referred to as the self employment tax. If you are both employed and self employed as I am, your employer pays their portion of FICA on the income you earn there, and you pay both halves on the income you earn in your business. Edit: As @JoeTaxpayer added in his comment, you can specify an extra amount to be withheld from your pay when you fill out your W-4 form. This is separate from the calculation of how much to withhold based on dependents and such; see line 6 on the linked form. This could allow you to avoid making quarterly estimated payments for your self-employment income. I think this is much easier when your side income is predictable. Personally, I find it easier to come up with a percentage I must keep aside from my side income (for me this is about 35%), and then I immediately set that aside when I get paid. I make my quarterly estimated payments out of that money set aside.  My side income can vary quite a bit though; if I could predict it better I would probably do the extra withholding. Yes, you need to pay taxes for FICA and federal income tax.  I can't say exactly how much you should withhold though. If you have predictable deductions and such, it could be lower than you expect. I'm not a tax professional, and when it comes doing business taxes I go to someone who is. You don't have to do that, but I'm not comfortable offering any detailed advice on how you should proceed there. I mentioned what I do personally as an illustration of how I handle withholding, but I can't say that that's what someone else should do. In Australia, any income you earn is taxable despite where it came from. Using your example your taxable income is $70,000. Keep in mind that with a business even as a sole trader any business expenses that contribute to the earning of your business income is deductible, reducing the final amount of tax you'll have to pay.  The ATO website has lots of good information and examples to look at including tax rates.  If your total income is pushing  into a higher tax bracket over 30c tax per $1 earned, it may be worth looking at shifting your business to operate under a company structure that just has a fixed tax rate around 30c per $1.  That said, for me, I don't want the paperwork overhead of a company yet so I'm running my side business as a sole trader too. I'd rather do that and keep it easy for now while my business gets profitable that waste time on admin structures for tax reasons even if in the shortterm it may mean slightly higher tax. In the end, you only pay tax on profit (income minus expenses) as opposed to raw/gross income.  For more info there are good books in the bookshops or local library (to read free) on starting a business on the side while still working. They discuss these issues too. Yes, if you can split your income up over multiple years it will be to your advantage over earning it all in one year.  The reasons are as you mentioned, you get to apply multiple deductions/credits/exemptions to the same income. Rather than just 1 standard deduction, you get to deduct 2 standard deductions, you can double the max saved in an IRA, you benefit more from any non-refundable credits etc. This is partly due to the fact that when you are filing your taxes in Year 1, you can't include anything from Year 2 since it hasn't happened yet. It doesn't make sense for the Government to take into account actions that may or may not happen when calculating your tax bill. There are factors where other year profit/loss can affect your tax liability, however as far as I know these are limited to businesses. Look into Loss Carry Forwarded/Back if you want to know more. Regarding the '30% simple rate', I think you are confusing something that is simple to say with something that is simple to implement.  Are we going to go change the rules on people who expected their mortgage deduction to continue? There are few ways I can think of that are more sure to cause home prices to plummet than to eliminate the Mortgage Interest Deduction. What about removing Student Loan Interest? Under a 30% 'simple' rate, what tools would the government use to encourage trade in specific areas? Will state income tax deduction also be removed? This is going to punish those in a state with a high income tax more than those in states without income tax. Those are all just 'common' deductions that affect a lot of people, you could easily say 'no' to all of them and just piss off a bunch of people, but what about selling stock though? I paid $100 for the stock and I sold it for $120, do I need to pay $36 tax on that because it is a 'simple' 30% tax rate or are we allowing the cost of goods sold deduction (it's called something else I believe when talking about stocks but it's the same idea?) What about if I travel for work to tutor individuals, can I deduct my mileage expenses? Do I need to pay 30% income tax on my earnings and principal from a Roth IRA? A lot of people have contributed to a Roth with the understanding that withdrawals will be tax free, changing those rules are punishing people for using vehicles intentionally created by the government. Are we going to go around and dismantle all non-profits that subsist entirely on tax-deductible donations? Do I need to pay taxes on the employer's cost of my health insurance? What about 401k's and IRA's? Being true to a 'simple' 30% tax will eliminate all 'benefits' from every job as you would need to pay taxes on the value of the benefits. I should mention that this isn't exactly too crazy, there was a relatively recent IRS publication about businesses needing to withhold taxes from their employees for the cost of company supplied food but I don't know if it was ultimately accepted. At the end of the day, the concept of simplifying the tax law isn't without merit, but realize that the complexities of tax law are there due to the complexities of life. The vast majority of tax laws were written for a reason other than to benefit special interests, and for that reason they cannot easily be ignored. "Yes, you will have to file taxes.  Each peson gets a standard deduction.  By ""claiming you"", your parents are applying your standard deduction to their taxes, meaning that you cannot use that same deduction on your taxes.  You still must pay taxes on your income.  This generally works out best overall, assuming that your parents are in a higher tax bracket (have a higher income) than you." Do I get a write off for paying student loans? Maybe.  See https://www.irs.gov/publications/p970/ch04.html Generally, personal interest you pay, other than certain mortgage interest, isn't deductible on your tax return. However, if your modified adjusted gross income (MAGI) is less than $80,000 ($160,000 if filing a joint return) there is a special deduction allowed for paying interest on a student loan (also known as an education loan) used for higher education. For most taxpayers, MAGI is the adjusted gross income as figured on their federal income tax return before subtracting any deduction for student loan interest. This deduction can reduce the amount of your income subject to tax by up to $2,500.  Read the whole document to be sure, but that's the basics.   You'll have to fill out a 1040 or 1040A to claim a student loan deduction.  It won't be on the 1040EZ.  You do not have to itemize though.   What kinds of write-offs and credits are available for someone who is single and lives in an apartment with two roommates? As a practical matter, in 2016 you'll get the standard deduction for someone who is single ($6300) and the personal exemption ($4050).  It's extremely unlikely that you'll be able to deduct more by itemizing.  Most people who itemize are taking a mortgage interest deduction.  Major medical bills are another possibility, but they have to be more than 10% of your adjusted gross income (it's one of the lines on your tax return).  Assuming you rent and are reasonably healthy, you are unlikely to have enough to itemize.   The most likely additional deduction would be the one for an IRA (Individual Retirement Account).  Although you might be better off doing a Roth anyway (no tax deduction).   If you are self-employed or making more than $100,000 a year, there are additional issues.  But most people aren't.  If you filled out a W-4 and will get a W-2 back, you aren't self-employed.  Hopefully you have a rough idea of your annual income.   The first $9275 over your deductions will pay 10%.  After that, up to $37,650 you pay 15%.  The 2016 link above has a link (PDF) to the full table if you need more than that.  Note that that is the first $48,000 in income with your $10,350 in deductions. Keep in mind, when talking about other deductions, such as mortgage interest, you need to look at your overall situation and whether the taxpayer is near the standard deduction amount. For some, their interest deduction and property tax are below the standard deduction, and therefore, they'd not itemize. "I disagree with @Sam's answers:  yes you will get that money back when your tax return is processed.  This is not true. You will receive funds that are in excess of your liability (contrary to popular belief, the government does not take more than what you are liable for).   ""is it possible to return the check and modify how it's calculated if I talk to payroll?""  No. When you sign your documents at the beginning of the year, that will dictate the amount of liability they take from each of your paychecks.  ""Will this difference be given back in my next tax return"" Because your company is withdrawing 25% on your paycheck you may/or may not need to pay more depending on the rest of your salary.  The IRS has set the system up as brackets. You pay your taxes based on the amount earned (voluntarily or involuntarily). So if you have income of $9,275 you would pay $923 in taxes at a marginal rate of 10% (and average rate of 10%). If you made $10,000, you would pay $923+$109=$1,032 with your marginal rate as 15% (while your average rate is 10.31%).  All in all, this is dependent on your salary, filing, and other deductions to raise or lower your tax liability.  Note: The $109 came from this: [(10,000-9,275)*.15]" "Does your spouse work? That's one factor that can put your income into a higher bracket. The one difference to note is you will pay 2x the social security portion, so even though not ""federal"" tax, its right off the top nearly 13%. I'm not familiar with your states tax. It's really worth dropping the $75 on a copy of the software and running your own exact numbers."
