What are FICA taxes for a sole proprietor in the United States
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.
"You probably don't need S-Corp. There's no difference between what you can deduct on your Schedule C and what you can deduct on 1120S, it will just cost you more money. Since you're gambling yourself, you don't need to worry about liability - but if you do, you should probably go LLC route, much cheaper and simpler. The ""reasonable salary"" trick to avoid FICA won't work. Don't even try. Schedule C for professional gamblers is a very accepted thing, nothing extraordinary about it." "You would put your earnings (and expenses, don't forget) on Schedule C, and then do a Schedule SE for self-employment tax. http://www.irs.gov/businesses/small/article/0,,id=98846,00.html 1040ES isn't used to compute taxes, it's used to pay taxes. Generally you are supposed to pay taxes as you go, rather than when you file. There are exceptions where you won't be penalized for paying when you file, ""most taxpayers will avoid this penalty if they owe less than $1,000 in tax after subtracting their withholdings and credits, or if they paid at least 90% of the tax for the current year, or 100% of the tax shown on the return for the prior year, whichever is smaller"" from http://www.irs.gov/taxtopics/tc306.html  i.e. there's a safe harbor as long as you pay as much as you owed the year before. If you owe a lot at the end of the year a second time in a row, then you get penalized." "It doesn't generally matter, and I'm not sure if it is in fact in use by the IRS other than for general statistics (like ""this year 20% of MFJ returns were with one spouse being a 'homemaker'""). They may be able to try and match the occupation and the general levels and types of income, but for self-employed there's a more precise and reliable field on Schedule C and for employees they don't really need to do this since everything is reported on W2 anyway. So I don't think they even bother or give a lot of value to such a metric. So yes, I'm joining the non-authoritative ""doesn't matter"" crowd." Do you have any insight on average *effective* rates paid by SE owners?  As a counterpoint to your (very valid) links, filing as S-corp allows for taxes on distributions to be exempt from payroll tax and taxed at much lower rates. Also, being SE allows for various deductions not possible for wage earners. There's probably other examples not immediately coming to mind.  Also, SE taxes equal taxes otherwise paid by employer + employee. It's just that those employer taxes don't appear on the employee's paystub so not everyone realizes this. First, the SSN isn't an issue. She will need to apply for an ITIN together with tax filing, in order to file taxes as Married Filing Jointly anyway. I think you (or both of you in the joint case) probably qualify for the Foreign Earned Income Exclusion, if you've been outside the US for almost the whole year, in which cases both of you should have all of your income excluded anyway, so I'm not sure why you're getting that one is better. As for Self-Employment Tax, I suspect that she doesn't have to pay it in either case, because there is a sentence in your linked page for Nonresident Spouse Treated as a Resident that says However, you may still be treated as a nonresident alien for the   purpose of withholding Social Security and Medicare tax. and since Self-Employment Tax is just Social Security and Medicare tax in another form, she shouldn't have to pay it if treated as resident, if she didn't have to pay it as nonresident. From the law, I believe Nonresident Spouse Treated as a Resident is described in IRC 6013(g), which says the person is treated as a resident for the purposes of chapters 1 and 24, but self-employment tax is from chapter 2, so I don't think self-employment tax is affected by this election. This is wrong.  It should be  or  Now, to get back to self-employment tax.  Self-employment tax is weird.  It's a business tax.  From the IRS perspective, any self-employed person is a business.  So, take your income X and divide by 1.0765 (6.2% Social Security and 1.45% Medicare).  This gives your personal income.  Now, to calculate the tax that you have to pay, multiply that by .153 (since you have to pay both the worker and employer shares of the tax).   So new calculation  or they actually let you do  which is better for you (smaller).   And your other calculations change apace.   And like I said, you can simplify Q1se to  and your payment would be  Now, to get to the second quarter.  Like I said, I'd calculate the income through the second quarter.  So recalculate A based on your new numbers and use that to calculate Q2i.   or  Note that this includes income from both the first and second quarters.  We'll reduce to just the second quarter later.  This also has you paying for all of June even though you may not have been paid when you make the withholding payment.  That's what they want you to do.   But we aren't done yet.  Your actual payment should be  or  Because Q2ft and Q2se are what you owe for the year so far.  Q1ft + Q1se is what you've already paid.  So you subtract those from what you need to pay in the second quarter.  In future quarters, this would be  All that said, don't stress about it.  As a practical matter, so long as you don't owe $1000 or more when you file your actual tax return, they aren't going to care.  So just make sure that your total payments match by the payment you make January 15th.   I'm not going to try to calculate for the state.  For one thing, I don't know if your state uses Q1i or Q1pi as its base.  Different states may have different rules on that.  If you can't figure it out, just use Q1i, as that's the bigger one.  Fix it when you file your annual return.  The difference in withholding is going to be relatively small anyway, less than 1% of your income. "Yep. You're single, you're possibly still a dependent on your parent's taxes (in lieu of rent), and you're finally bringing home bacon instead of bacon bits. Welcome to the working world. Let's say your gross salary is the U.S. median of $50,000. With bi-weekly checks (26 a year; common practice) you're getting $1923.08 per paycheck. In the 2013 ""Percentage Method"" tax tables, here's how your federal withholding is calculated as a single person paid biweekly: Federal taxes are computed piecewise; the amount up to A is taxed at X%, then the amount between A and B is taxed at Y%, so if you make $C, between A and B, the tax is (A*X) + (C-A)*Y. The amount A*X is included in the ""base amount"" for ease of calculation. Back to our example; let's say you're getting $1923.08 gross wages per check. That puts you in the 25% marginal bracket. You pay the sum of all lesser brackets (which is the ""base amount"" of the 25% bracket), plus the 25% marginal rate on every dollar that falls within the bracket. That's 191.95 + (1923.08 - 1479) * .25 = 191.95 + (444.08 * .25) = 191.95 + 111.02 = $302.97 per paycheck. The ""effective"" tax rate on the total amount, as if you were being charged a flat tax, is 15.75%, and this is just for the federal income tax. Add to this MA state income taxes (5.25% flat tax), FICA (aka Medicare; 1.45% flat) and SECA (aka Social Security; 6.2% up to a ""wage base"" that $50k doesn't even approach), and your effective tax rate on each dollar you earn is 15.75% + 5.25% + 1.45% + 6.2% = 28.65%. This doesn't include any state unemployment taxes that may be withheld separately, but as the rate I come up with is pretty darn close to what you've figured (meaning I slightly overestimated your gross income and thus your effective tax rate), my bet is that SUTA's either employer-paid in MA, or it's just part of MA state income tax. It gets better, at least at the federal level: The amount of your state income taxes is tax-deductible at the federal level if you itemize your deductions. That may not be a factor for you as you'd have to come up with more than $6,100 of other tax-deductible expenses to make itemizing the better option than taking the standard deduction (big-ticket items are mortgage expenses other than principal payments, hospital stays such as for childbirth or major accident, and state and local taxes such as sales, property and income). If you can claim yourself as a dependent (meaning your parents can't), then $150 of each check ($3,900 of your annual salary) is no longer taxed for federal withholding, lowering the amount of money taxed at the 25% marginal rate. You effectively save $37.50 biweekly ($975 annually) in taxes. Get married and file jointly, and your spouse, her personal exemption, and an extra standard deduction amount (if you don't itemize) go on your taxes. The tax rates for married couples filing jointly are also lower; they're currently calculated (or were in 2012) to be the same as if two equal earners were to file separately, so if your spouse doesn't work, your taxes on the single income are calculated at the rates you'd get if you earned half as much. It doesn't work out to half the taxes, but it is a significant ""marriage advantage"". Have kids, and each one is another little $3,900 tax write-off. It's nowhere near the cost of having or raising the child, but it helps, and having kids isn't about the money. Owning a home, making charitable deductions, having medical expenses, etc are a toss-up. The magic number in 2013 is $12,200 for a married couple, $6,100 for a single person. If your mortgage interest, insurance premiums, property taxes, medical expenditures, charitable donations, any contributions from your take-home pay to a tax-deferred savings account (typically these accounts are paid into by your employer as a ""pre-tax deduction"" and never show up as taxable income, but you could just as easily move money from your take-home pay into tax-deferred savings) and any other tax-deductible payments add up to more than 12 large, then itemize. If not, take your standard deduction. As a single taxpayer just starting out in life, you probably don't have any of these types of expenditures, certainly not enough to give up the SD. I did the math on my own taxes in 2012, and was surprised at how little the government actually gets of my paycheck when all's said and done. Remember back in the summer of 2012 when everyone was mad at Romney for making millions and only paying an effective income tax rate of 14%, which was compared to the middle class's marginal rate of 25-28%? Well, my family of 3, living on a little more than the median income from one earner (me), taking the married standard deduction, three personal exemptions, and a little extra for student loan interest, paid an effective federal income tax rate of something like 3.5%. Of course, the FICA and SS taxes don't allow any deductions (not even for retirement savings), so add in the 4.2% SS (in 2012) and 1.45% FICA and the full federal gimme was more like 9-10%." This author is conflating a sole proprietorship and a one-man shop.  Sole proprietorship is a tax designation as to who *owns* the business; an individual rather than a shareholder(s) or partner.

That Employees don't pay or often even know about, yet some of us small business owners are also employees, so we get double taxed... "Even though you will meet the physical presence test, you cannot claim the FEIE because your tax home will remain the US. From the IRS: Your tax home is the general area of your main place of business, employment, or post of duty, regardless of where you maintain your family home. Your tax home is the place where you are permanently or indefinitely engaged to work as an employee or self-employed individual. Having a ""tax home"" in a given location does not necessarily mean that the given location is your residence or domicile for tax purposes.   ...   You are not considered to have a tax home in a foreign country for any period in which your abode is in the United States. However, your abode is not necessarily in the United States while you are temporarily in the United States. Your abode is also not necessarily in the United States merely because you maintain a dwelling in the United States, whether or not your spouse or dependents use the dwelling.   ...   The location of your tax home often depends on whether your assignment is temporary or indefinite. If you are temporarily absent from your tax home in the United States on business, you may be able to deduct your away from home expenses (for travel, meals, and lodging) but you would not qualify for the foreign earned income exclusion. If your new work assignment is for an indefinite period, your new place of employment becomes your tax home, and you would not be able to deduct any of the related expenses that you have in the general area of this new work assignment. If your new tax home is in a foreign country and you meet the other requirements, your earnings may qualify for the foreign earned income exclusion.   If you expect your employment away from home in a single location to last, and it does last, for 1 year or less, it is temporary unless facts and circumstances indicate otherwise. If you expect it to last for more than 1 year, it is indefinite.   If you expect your employment to last for 1 year or less, but at some later date you expect it to last longer than 1 year, it is temporary (in the absence of facts and circumstances indicating otherwise) until your expectation changes. For guidance on how to determine your tax home refer to Revenue Ruling 93-86. Your main place of business is in the US and this will not change, because your business isn't relocating. If you are intending to work remotely while you are abroad, you should get educated on the relevant laws on where you are going. Most countries don't take kindly to unauthorized work being performed by foreign visitors. And yes, even though you aren't generating income or involving anyone in their country, the authorities still well may disapprove of your working. My answer to a very similar question on Expatriates." Your tax return will be due on April 18th of 2017 for the amounts made in 2016. Based on the figures that you have provided, assuming you are 18, and assuming you are a single taxpayer your total tax will be around $2600.00 ($2611.25 to be exact, without additional credits or deductions to AGI accounted for). The $1,234 in fed. inc. tax that you have already paid is considered to be a prepaid by the government. If at year-end you have provided more than you have made the government will refund you the excess (federal tax return). 401k contributions are exempt from employee and employer FICA withholding.  The employer withholding is approximately 7% of the gross.  The closer the employer match ratio is to 7%, the closer it is to paying for itself.  Example: Assuming an employee is match-maximizing and in very round numbers grosses 100,000 per year.  A 50% match schedule is about $350 cheaper per employee than a 100% match schedule: Default non participant: The employee will see about 7000 deducted for FICA, and the employer will pay 7000 to FICA if they don't participate.   First case: the match is 100%, 1-for-1 to a 5% cap, the employee will deduct 5000, and have 6650 withheld for FICA.  The employer will pay 6650 to FICA.  The total employer cost of withholding and match is 11,650.   Second case: If the match is 50%, 1-for-2 to a 5% cap, the employee will deduct 10000, and have 6300 withheld for FICA.  The employer will pay 6300 to FICA.  The total employer cost of withholding and match is 11,300. Yes, you need to include income from your freelance work on your tax return.  In the eyes of the IRS, this is self-employment income from your sole-proprietorship business. The reason you don't see it mentioned in the 1040EZ instructions is that you can't use the 1040EZ form if you have self-employment income.  You'll need to use the full 1040 form.  Your business income and expenses will be reported on a Schedule C or Schedule C-EZ, and the result will end up on Line 12 of the 1040.  Take a look at the requirements at the top of the C-EZ form; you probably meet them and can use it instead of the more complicated C form. If you have any deductible business expenses related to your freelance business, this would be done on Schedule C or C-EZ. If your freelance income was more than $400, you'll also need to pay self-employment tax.  To do this, you file Schedule SE, and the tax from that schedule lands on form 1040 Line 57. "There are a few sites out there that can give you some reasoning behind the request. LegalZoom, for instance.  To quote the LZ doc in case the link dies: Employee vs. Independent Contractor If a worker is an employee, the employer is responsible for paying   Social Security, unemployment insurance, Medicare, and possibly other   costs like workers' compensation insurance for the employee; at the   end of the tax year, the employer is responsible for compiling all   necessary payroll reports, including W-2 forms. If a worker is an independent contractor, the employer is not   responsible for any of the above taxes or payments, and the only added   paperwork is the issuing of a 1099 to the independent contractor at   the end of the tax year, if he or she has made more than $600 with the   employer. As Kent suggested, you should speak with an attorney (really you need one if setting up an LLC). There are a lot of companies out there these days that try to classify people as contractors rather than full-time employees as it gets them out of paying benefits and dealing with taxes. This is being heavily cracked down on, and several ""contractor"" employees are winning lawsuits to get full-time status.  If you are truly acting as a contractor, then setting up an LLC can help with a few items such as taxes and protection on certain business aspects (see comments below regarding this). It's easy and relatively cheap (cost me about $250 with extra legal advice tacked on). If you are reporting directly to a manager with the company, or really working in any way that isn't consistent with the definition of a contractor, then I'd turn down the offer and ask to be made a FT employee.  Additional information: https://www.sba.gov/content/hire-contractor-or-employee" I'm also self employed. Your circumstances may be different, but my accountant told me there was no reason to pay more than 100% of last years' taxes. (Even if this years' earnings are higher.) So I divide last year by 4 and make the quarterlies. As an aside, I accidentally underpaid last year (mis-estimated), and the penalty was much smaller than I expected.
