W-4 and withholding taxes for self-employed spouse
"Littleadv is incorrect because receiving a 1099 means she will be taxed self-employment tax on top of federal income taxes. Your employer will automatically withhold 7.65% of payroll taxes as they pay you each paycheck and then they'll automatically pay the other half of your payroll tax (an additional 7.65%) to bring it to a total of 15.3%. In other words, because your wife is technically self employed, she will owe both sides of payroll tax which is 15.3% of $38k = $5,800 on TOP of your federal income tax (which is the only thing the W-4 is instructing them about what amount to withhold). The huge advantage to a 1099, however, is that she's essentially self-employed which means ALL of the things she needs to run her business are deductible expenses. This includes her car, computer, home office, supplies, sometimes phone, gas, maintenance, travel expenses, sometimes entertainment, etc - which can easily bring her ""income"" down from $38k to lets say $23k, reducing both her federal income tax AND self-employment tax to apply to $15k less (saving lets say 50% of $15k = $7.5k with federal and self employment because your income is so high). She is actually supposed to pay quarterly taxes to make up for all of this. The easy way to do this is each quarter plug YOUR total salary + bonus and the tax YOU have paid so far (check your paystubs) into TurboTax along with her income so far and all of her expenses. This will give you how much tax you can expect to have left to owe so far--this would be your first quarter. When you calculate your other quarters, do it the exact same way and just subtract what you've already paid so far that year from your total tax liability." With your income so high, your marginal tax rate should be pretty easy to determine.  You are very likely in the 33% tax bracket (married filing jointly income range of $231,450 to $413,350), so your wife's additional income will effectively be taxed at 33% plus 15% for self-employment taxes. Rounding to 50% means you need to withhold $19,000 over the year (or slightly less depending on what business expenses you can deduct). You could use a similar calculation for CA state taxes. You can either just add this gross additional amount to your withholdings, or make an estimated tax payment every quarter.  Any difference will be made up when you file your 2017 taxes. So long as you withhold 100% of your total tax liability from last year, you should not have any underpayment penalties. When you enter your expected gross income into the worksheet - just enter $360000 and leave everything else as is. That should give you the right numbers. Same for State (form DE-4).
"It's not possible to determine whether you can ""expect a refund"" or whether you are claiming the right number of exemptions from the information given.   If your wife were not working and you did not do independent contracting, then the answer would be much simpler.  However, in this case, we must also factor in how much your contracting brings in (since you must pay income tax on that, as well as Medicare and, probably, Social Security), whether you are filing jointly or separately, and your wife's income from her business.   There are also other factors such as whether you'll be claiming certain child care expenses, and certain tax credits which may phase out depending on your income.   If you can accurately estimate your total household income for the year, and separate that into income from wages, contracting, and your wife's business, as well as your expenses for things like state and local income and property taxes, then you can make a very reasonable estimate about your total tax burden (including the self-employment taxes on your non-wage income) and then determine whether you are having enough tax withheld from your paycheck.  Some people may find that they should have additional tax withheld to compensate for these expenses (see IRS W-4 Line #6)." You must pay your taxes at the quarterly intervals. For most people the withholding done by their employer satisfies this requirement. However, if your income does not have any withholding (or sufficient), then you must file quarterly estimated tax payments.  Note that if you have a second job that does withhold, then you can adjust your W4 to request further withholding there and possibly reduce the need for estimated payments.  Estimated tax payments also come into play with large investment earnings. The amount that you need to prepay the IRS is impacted by the safe harbor rule, which I am sure others will provide the exact details on. "However this seems off because I would essentially be purposely   filling out a form incorrectly. Note that the only part of the W-4 form that is required to be filled out and given to the employer is the small certificate at the bottom that you tear off. In this part, it only asks you for ""Total number of allowances you are claiming"". You don't have to fill out any of the worksheets in the other parts of the form, which actually ask for specific information. Since there are different allowed ways of computing the ""Total number of allowances you are claiming"", I doubt that any number you put there can be said to be ""incorrect"". I think that the best to use the IRS Withholding Calculator. If you use it, the calculator will probably tell you to claim a few more exemptions. And you don't have to feel bad about ""filling the form incorrectly"" if you follow the IRS calculator." 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. 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. 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). While the OP disses the health insurance coverage offered through his wife's employer as a complete rip-off, one advantage of such coverage is that, if set up right (by the employer), the premiums can be paid for through pre-tax dollars instead of post-tax dollars. On the other hand,  Health insurance premiums cannot be deducted on Schedule C by self-employed persons. So the self-employed person has to pay both the employer's share as well as the employee's share of Social Security and Medicare taxes on that money. Health insurance premiums can be deducted on Line 29 of Form 1040 but only for those months during which the Schedule C filer is neither  covered nor eligible to be covered by a subsidized health insurance plan maintained by an employer of the self-employed person (whose self-employment might be a sideline) or the self-employed person's spouse. In other words, just having the plan coverage available through the wife's employment, even though one disdains taking it, is sufficient to make a Line 29 deduction impermissible.  So, AGI is increased. Health insurance premiums can be deducted on Schedule A but only to the extent that they (together with other medical costs) exceed 10% of AGI. For many people in good health, this means no deduction there either. Thus, when comparing the premiums of health insurance policies, one should pay some attention to the tax issues too. Health insurance  through a spouse's employment might not be that bad a deal after all. Your question begins with a misunderstanding.  When you prepare your tax return (Form 1040/1040A/1040EZ) you always try to minimize your total tax bill.  When you fill out form W4 you trying to estimate how much tax will be shown on next years tax return.  The penalty for having too much tax withheld is not having the use of the money until you get a tax refund. At the moment interest rates are very low and your economic loss is the temporary loss of access to the money. One exception would be if you are carrying credit card debt. In that case you are, in effect, paying 20-30% interest to borrow money you lending to the US Treasury for 0% interest. The penalty for having too little tax withheld is having to make a large payment with your tax return. If your pre-payments aren't at least as much as your total income tax from last year there may also be modest underpayment penalty based on the difference between your pre-payments and your total income tax from last year or this year whichever is less. A large underpayment will trigger a different larger underpayemnt penalty. The W4 combined with the withholding rates tends to over-withhold income tax for most, but not all, taxpayers. Most people don't have enough savings to pay a large tax due, which leads to more penalties and an even larger bill. Over-witholding protects the overall tax system from the consequences of those events. People tend to be very unhappy, not quietly. On balance your greatest economic benefit depends on whether or not you have high interest debt. If you do, then accurate and even slightly under-withholding will probably work to your advantage as long as you can pay next 4/15. If not, avoiding the chance of having any unexpected balance due next year may be more important. For federal taxes the rule is fairly straight forward, assuming that nothing else changes during the year.  If you know your marginal tax rate (the rate that your last dollar of income is taxed at) last year then adding or subtracting an allowance on the w-4 form will move the amount withheld by rate x Personal exemption amount. The personal exemption for federal taxes in 2017 is $4,050. Lowering the number of allowances on the Federal W-4 increases the amount of money withheld during the year.  So for your federal W-4 form lowering the number of allowances by one if you are in the 25% bracket will cause an additional 25%x4050 or  ~$1012 a year to be withheld. Of course making the change 5/12ths of the way trough the year will mean that it will only increase the  the amount withheld the rest of the year by (7/12) * $1012 or ~$590 for the rest of the year. State taxes can be more complex due to issues regarding tax brackets, and the differences in how they calculate their taxes. Most state websites have a worksheet for making an adjustment  to their version of the W-4. Here is the form DE-4 form for California In your situation getting the numbers on the federal and state forms will be much more complex, because your combined  income for 2017 will be significantly different than your combined income for 2016.  In the case of multiple incomes getting the withholding correct is much harder even with stable income. The trick is that making the adjustment on the job with the highest income may not move the amount withheld as much as you expect. For example if the largest income is only withheld at the 15% rate but your combined income from all your combined jobs results in you being in the 25% bracket, then the above calculation would only move the amount withheld by $354 instead of $590. A couple of notes: the number of allowances on the federal and state W-4 forms don't have to match. Mine almost never do. The number of allowances on the W-4 forms doesn't have to match the number of exemptions on the 1040 form. Checkout the worksheet on page 20 of Pub 535.  Also the text starting in the last half of the third column of page 18 onward. https://www.irs.gov/pub/irs-pdf/p535.pdf The fact that you get a W-2 is irrelevant as far as I can see.  Your self-employment business has to meet some criteria (such as being profitable) and the plan needs to be provided through your own business (although if you're sole proprietor filing on Schedule C, it looks like having it in your own name does the trick).  Check the publication for all of the rules. There is this exception that would prevent many people with full-time jobs on W-2 from taking the deduction: Other coverage. You cannot take the deduc­tion for any month you were eligible to partici­pate in any employer (including your spouse's) subsidized health plan at any time during that month, even if you did not actually participate. In addition, if you were eligible for any month or part of a month to participate in any subsidized health plan maintained by the employer of ei­ther your dependent or your child who was un­der age 27 at the end of 2014, do not use amounts paid for coverage for that month to fig­ure the deduction. (Pages 20-21).  Sounds like in your case, though, this doesn't apply. (Although your original question doesn't mention a spouse, which might be relevant to the rule if you have one and he/she works.) The publication should help.  If still in doubt, you'll probably need a CPA or other professional to assess your individual situation. "That $200 extra that your employer withheld may already have been sent on to the IRS. Depending on the size of the employer, withholdings from payroll taxes (plus employer's share of Social Security and Medicare taxes) might be deposited in the US Treasury within days of being withheld. So, asking the employer to reimburse you, ""out of petty cash"" so to speak, might not work at all.  As JoeTaxpayer says, you could ask that $200 less be withheld as income tax from your pay for the next pay period (is your Federal income tax withholding at least $200 per pay period?), and one way of ""forcing"" the employer to withhold less is to file a  new W-4 form with Human Resources/Payroll, increasing the number of  exemptions to more than you are entitled to, and then filing a new W-4 changing your exemptions back to what they are right now once when you have had $200 less withheld. But be careful. Claims for more exemptions than you are entitled to can be problematic, and the IRS might come looking if you suddenly ""discover"" several extra children for whom you are entitled to claim exemptions." "First, filing status. If you and your wife are legally married, you should be filing your tax returns as married, either jointly or separately. In the US, ""head of household"" has a specific meaning and is for unmarried people who are supporting one or more relatives, per the IRS. If you are working full-time and your wife is not, then likely you will file a joint return, including all your income and all the expenses for your wife's business. So yes, the losses in her business will offset your income. Depending on how complex things are, you may want to hire a professional to help with your taxes. The rules for what can and cannot be deducted as a business expense can be opaque." "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." Both states will want to tax you. Your tax home is where you maintain a domicile, are registered to vote, etc. and you will probably want to keep this as MA since you state that MA is your permanent residence and you are staying in a rented place in PA. But be careful about voter registration; that is one of the items that can be used to determine your state of residence.  OK, so if you and your spouse are MA residents,  you should file jointly as residents in MA and as nonresidents in PA. Do the calculations on the nonresident return first, and then the calculations on the resident  return. Typically, on a nonresident tax return, the calculations are effectively the following: Report all your income (usually AGI from the Federal return).  Call this $X. Compute the PA state tax due on $X.  Note that you follow the rules for nonresidents in doing this, not the calculations used by PA residents. Call the amount of tax you computed as $Y. What part of the total income $X is attributable to PA sources? If this amount is $Z, then you owe PA $Y times (Z/X). On the resident return in MA, you will likely get some credit for the taxes paid to PA, and this will reduce your MA tax burden. Usually the maximum credit is limited to the lesser of actual tax paid to PA and what you would have had to pay MA for the same income. As far as withholding is concerned, your employer in PA will withhold PA taxes as if you are a PA resident, but you can adjust the amount via the PA equivalent of IRS Form W4 so as to account for any additional  tax that might be due because you will be filing as a nonresident.  Else you can pay estimated taxes via the PA equivalent of IRS Form 1040ES. Similarly, your wife can adjust her withholding to account for the MA taxes that you will owe on the joint income, or you can pay estimated taxes to MA too. Note that it is unlikely that your employer in Pennsylvania will withhold  Massachusetts taxes (and send them to Massachusetts) for you, e.g. if it is a ma-and-pa store, but there may be special deals available if  your employer does business in both states, i.e. is a MA-and-PA store. I'm not sure why you're confusing the two unrelated things. 1040ES is your estimated tax payments. 941 is your corporation's payroll tax report. They have nothing to do with each other. You being the corporation's employee is accidental, and can only help you to avoid 1040ES and use the W2 withholding instead - like any other employee. From the IRS standpoint you're not running a LLC - you're running a corporation, and you're that corporation's employee. While technically you're self-employed, from tax perspective - you're not (to the extent of your corporate salary, at least).
