$65000/year or $2500 every two weeks: If I claim 3 exemptions instead of zero, how much would my take home pay be?
"Take a look at IRS Publication 15. This is your employer's ""bible"" for withholding the correct amount of taxes from your paycheck. Most payroll systems use what this publication defines as the ""Percentage Method"", because it requires less data to be entered into the system in order to correctly compute the amount of withholding. The computation method is as follows: Taxes are computed ""piecewise""; dollar amounts up to A are taxed at X%, and then dollar amounts between A and B are taxed at Y%, so total tax for B dollars is A*X + (B-A)*Y. Here is the table of rates for income earned in 2012 on a daily basis by a person filing as Single: To use this table, multiply all the dollar amounts by the number of business days in the pay period (so don't count more than 5 days per week even if you work 6 or 7). Find the range in which your pay subject to withholding falls, subtract the ""more than"" amount from the range, multiply the remainder by the ""W/H Pct"" for that line, and add that amount to the ""W/H Base"" amount (which is the cumulative amount of all lower tax brackets). This is the amount that will be withheld from your paycheck if you file Single or Married Filing Separately in the 2012 TY. If you file Married Filing Jointly, the amounts defining the tax brackets are slightly different (there's a pretty substantial ""marriage advantage"" right now; withholding for a married person in average wage-earning range is half or less than a person filing Single.). In your particular example of $2500 biweekly (10 business days/pp), with no allowances and no pre-tax deductions: So, with zero allowances, your employer should be taking $451.70 out of your paycheck for federal withholding. Now, that doesn't include PA state taxes of 3.07% (on $2500 that's $76.75), plus other state and federal taxes like SS (4.2% on your gross income up to 106k), Medicare/Medicaid (1.45% on your entire gross income), and SUTA (.8% on the first $8000). But, you also don't get a refund on those when you fill out the 1040 (except if you claim deductions against state income tax, and in an exceptional case which requires you to have two jobs in one year, thus doubling up on SS and SUTA taxes beyond their wage bases). If you claim 3 allowances on your federal taxes, all other things being equal, your taxable wages are reduced by $438.45, leaving you with taxable income of $2061.55. Still in the 25% bracket, but the wages subject to that level are only $619.55, for taxes in the 25% bracket of $154.89, plus the withholding base of $187.20 equals total federal w/h of $342.09 per paycheck, a savings of about $110pp. Those allowances do not count towards other federal taxes, and I do not know if PA state taxes figure these in. It seems odd that you would owe that much in taxes with your withholding effectively maxed out, unless you have some other form of income that you're reporting such as investment gains, child support/alimony, etc. With nobody claiming you as a dependent and no dependents of your own, filing Single, and zero allowances on your W-4 resulting in the tax withholding above, a quick run of the 1040EZ form shows that the feds should owe YOU $1738.20. The absolute worst-case scenario of you being claimed as a dependent by someone else should still get you a refund of $800 if you had your employer withhold the max. The numbers should only have gotten better if you're married or have kids or other dependents, or have significant itemized deductions such as a home mortgage (on which the interest and any property taxes are deductible). If you itemize, remember that state income tax, if any, is also deductible. I would consult a tax professional and have him double-check all your numbers. Unless there's something significant you haven't told us, you should not have owed the gov't at the end of the year." I use paycheckcity.com and first punch in my paycheck and make sure it calculates within a few pennies the value of my actual paycheck. Then I fiddle with withholding values, etc. to see the effect of change.  It has been very effective for me over the years. It will usually take a week or two for changes to your withholding to take effect in payroll.  However 0 deductions will withhold more per check than 3.  So if at 0 deductions you are having to pay in April then I would suggest not changing your W2 to 3 deductions.  Instead in the section for extra with holding add $25 per week.  This should leave you with a more manageable return in April.
"In general, you are allowed to deduct up to $50/month per student (see page 4), but only if you aren't reimbursed. In your case, since you are receiving a stipend, the full $2000 will be treated as taxable income. But the question of ""is it worth it"" really depends on how much you will actually spend (and also what you'll get from the experience). Suppose you actually spend $1000/month to host them, and if your combined tax rate is 35%, you'll pay $700 in additional taxes each month, but you'll still profit $300 each month. If your primary motivation for hosting students is to make a profit, you could consider creating a business out of it. If you do that you will be able to deduct all of your legitimate business expenses which, in the above example, would be $1000/month. Keeping with that example, you would now pay taxes on $1000 instead of $2000, which would be $350, meaning your profit would now be $650/month. (Increasing your profit by $350/month.) You will only need to keep spending records if you plan to go the business route. My advice: assume you won't be going the business route, and then figure out what your break even point is based on your tax rate (Fed+state+FICA). The formula is: Max you can spend per month without losing money = 2000 - (2000 * T) e.g. if T = 35%, the break even point is $1300. Side note: My family hosted 5 students in 5 years and it was always a fantastic experience. But it is also a very big commitment. Teenagers eat a lot, and they drive cars, and go on dates, and play sports, and need help with their homework (especially English papers), and they don't seem to like bed times or curfews. IMHO it's totally worth it, even without the stipend..." The basis of the home is the cost of land and material. That's it.  Your time isn't added to basis. No different than if you spend 1000 hours in a soup kitchen. You deduct miles for your car and expenses you can document but you can't deduct your time.  Over 2 years, you could have a gain up to $500K per married couple and pay no tax. Math time.  24 means 2 years out of college, or 6 years out of highschool, the latter being much more plausible given the poster's content quality.  $100k / 6 = $16.7k/year  16.7k / 52 weeks = $321/week  $321 / (11/hr * (1 - 15% taxes)) = 34 hours per week.  So he worked 34 hours per week, without fail, for 6 years, with NO expenses of any kind whatsoever.   OR, much more likely, he managed to save only $10k, not $100k in 6 years. I know this is rather late, but with your income it is almost certainly better for your mother to claim you as a dependent. I was in a similar situation this last year, I didn't get the full weight of the tax break because my taxes went down to zero with this exemption along with claiming myself as a dependent. I used Turbotax to run both our taxes both ways to verify, the difference was about 1000 dollars saved for my parents to claim me as a dependent vs claiming myself as a dependent.    If you are unsure it doesn't take long to run the numbers through Turbotax, TaxACT, or some similar software. "I'll start with a question... Is the 63K before or after taxes?  The short answer to your question on how much is reasonable is: ""It depends."" It depends on a lot more than where you live, it depends on what you want... do you want to pay down debt? Do you want to save? Are you trying to buy a house? Those will influence how much you ""can"" (should let yourselves) spend. It also depends on your actual salary... just because I spend 5% of my salary on something doesn't mean bonkers to you if you're making 63,000 and I'm only making 10,000.  I also have a lot of respect for you trying to take this on. It's never easy. But I would also recommend you start by trying to see what you can do to track how much you are actually spending. That can be hard, especially if you mostly use cash.  Once you're tracking what you spend, I still think you're coming at this a bit backwards though... rather than ask 'how much is reasonable' to spend on those other expenses, you basically need to rule out the bigger items first. This means things like taxes, your housing, food, transportation, and kid-related expenses. (I've got 2.5 kids of my own.) I would guess that you're listing your pre-tax salaries on here... so start first with whatever it costs you to pay taxes. I'm a US citizen living in Berlin, haven't filed UK taxes, but uktaxcalculators.co.uk says that on 63,000 a year with 3 deductions your net earnings will actually be 43,500. That's 3,625/month.  Then what does it cost you each month for rent/utilities/etc. to put a house over your family's head? The rule of thumb they taught in my home-economics class was 35-40%, but that's not for Europe... you'll know what it costs. Let's say its 1,450 a month (40%) for rent and utilities and maybe insurance. That leaves 2,175.  The next necessity after housing is food. My current food budget is about 5-6% of my after-tax salary. But that may not compare... the cost to feed a family of 3 is a fairly fixed number, and our salaries aren't the same. As I said, I am a US expat living in Berlin, so I looked at this cost of living calculator, and it looks like groceries are about 7-10% higher there around Cardiff than here in Germany. Still, I spend about 120 € per week on food. That has a fair margin in it for splurging on ice cream and a couple brewskies. It feeds me (I'm almost 2m and about 100 kilos) and my family of four. Let's say you spend 100£ a week on groceries. For budgeting, that's 433£ a month. (52 weeks / 12 months == 4.333 weeks/month) But let's call it 500£. That leaves 1,675.  From here, you'll have to figure out the details of where your own money is going--that's why I said you should really start tracking your expenses somehow... even just for a short time. But for the purposes of completing the answers to your questions, the next step is to look at saving before you try spending anything else. A nice target is to aim for 10% of your after-tax pay going into a savings account... this is apart from any other investments. Let's say you do that, you'll be putting away 363£ per month. That leaves 1,300£.  As far as other expenses... you need some money for transport. You haven't mentioned car(s) but let's say you're spending another 500£ there. That would be about enough to cover one with the petrol you need to get around town. That leaves 800£ As far as a clothing budget and entertainment, I usually match my grocery budget with what I call ""mad money"". That's basically money that goes towards other stuff that I would love to categorize, but that my wife gets annoyed with my efforts to drill into on a regular basis. That's another 500£, which leaves 300£.  You mentioned debts... assuming that's a credit card at around 20% interest, you probably pay 133£ a month just in interest... (20% = 0.20 / 12 = 0.01667 x 8,000 = 133) plus some nominal payment towards principal. So let's call it 175£. That leaves you with 125£ of wiggle room, assuming I have even caught all of your expenses. And depending on how they're timed, you are probably feeling a serious squeeze in between paychecks. I recognize that you're asking specific questions, but I think that just based on the questions you need a bit more careful backing into the budget. And you REALLY need to track what you're spending for the time being, until you can say... right, we usually spend about this much on X... how can we cut it out?  From there the basics of getting your financial house in order are splattered across the interwebs. Make a budget... stick to it... pay down debts... save. Develop goals and mini incentives/rewards as a way to make sure your change your psyche about following a budget." House rent allowance:7500 House Rent can be tax free to the extent [less of] Medical allowance : 800 Can be tax free, if you provide medical bills. Conveyance Allowance : 1250 Is tax free.  Apart from this, if you invest in any of the tax saving instruments, i.e. Specified Fixed Deposits, NSC, PPF, EPF, Tution Fees, ELSS, Home Loan Principal etc, you can get upto Rs 150,000 deductions. Additional Rs 50,000 if you invest into NPS. If you have a home loan, upto Rs 200,000 in interest can be deducted. So essentially if you invest rightly you need not pay any tax on the current salary, apart from the Rs 200 professional tax deducted. You will most likely pay around 30%, between standard income tax and payroll taxes. That is a good place to start. If you live in a state/city with income taxes, add that to the mix. Yes, you can do what you are contemplating doing, and it works quite well. Just don't get the university's payroll office too riled by going in each June, July, August and September to adjust your payroll withholding! Do it at the end of the summer when perhaps most of your contract income for the year has already been received and you have a fairly good estimate for what your tax bill will be for the coming year. Don't forget to include Social Security and Medicare taxes (both employee's share as well as employer's share) on your contract income in estimating the tax due. The nice thing about paying estimated taxes via payroll deduction is that all that tax money can be counted as having been paid in four equal and timely quarterly payments of estimated tax, regardless of when the money was actually withheld from your university paycheck. You could (if you wanted to, and had a fat salary from the university, heh heh) have all the tax due on your contract income withheld from just your last paycheck of the year! But whether you increase the withholding in August or in December, do remember to change it back after the last paycheck of the year has been received so that next year's withholding starts out at a more mellow pace. Your phrasing of the question isn't very clear, but I believe you're asking: Does our total household income classify us as tax exempt? Or, can we avoid filing taxes if we make $22,500 or less per year? The answer is no. Your tax liability will be very low, and if you have dependents or other deductible expenses (mortgage interest, 401K contributions, etc.), you're likely looking at a close to $0 liability. You still have to file your taxes, and you can't claim exempt on your W-4. Even if you did qualify to be tax exempt, you still have to file taxes. The are a couple of explanations that I can think of; though for determining exactly what is different you will want to print out both returns and compare them line by line to see how they differ. If the company grossed up your income to account for the taxes on housing (possibly by paying the additional withholding), you may be just benefiting from them estimating your tax rate. This can especially be the case if your only work was the three month internship. They would have to assume your salary was for the entire year. There is an earned income tax credit for low wage earners that you may have qualified for (it would depend your specific circumstances if you meet the criteria). But that credit for a range of income actually pays out more the more you earn (to encourage working that extra hour instead of reducing benefit because you had another hour of employment). As for the housing subsidy itself, while the value is quite high the IRS considers that to be a taxable benefit that the employer provided you and so it needs to be added to your W-2 wages. $8k a month seems quite high, but I don't know the quality of the apartment you were provided and what the going rates are in the area. Given that you said you worked for a major tech company, I can imagine that you might have been working in an area with high rents. If the employer did gross up your paycheck so as to cover your taxes, that $24k would also include that extra tax payment (e.g. if the employer paid $8k in additional taxes for you, then the housing cost that they directly paid were $16k). For estimating your take home salary, I suggest using one of the many free salary calculators available over the Internet. I personally use PaycheckCity.com, but there are plenty of others available. To calculate your allowances for the US Federal tax, you can use the worksheet attached to the form W-4.  Similar form (with a similar worksheet) is available for state taxes, on the Illinois Department of Revenue web site. This is a frequent problem for anyone with a large amount of deductions, whether it is student loan interest, home mortgage interest, charitable contributions, or anything else.  As an employee getting your tax withheld from your check, your options to reduce the amount withheld are limited. The HR department has no control over how much they withhold; the amount is calculated using a standard formula based on the number of exemptions you tell them.  The number of exemptions you claim on your W-4 form does not have to match reality. If you currently have 1 exemption claimed, ask them what the withholding would be if you claimed 4 exemptions. If that's not enough, go higher. As long as you are not withholding so little that you have a large tax bill at the end of the year, you are fine.  Of course, when you do your taxes, you need to have the correct number of exemptions claimed on your 1040, but this number does not need to match your W-4. The Australian Tax Office website shows Tax Rates for individuals based on the income earned in the Financial Year. Calculating what you'll be taxed For instance, it show that every dollar you earn up to $18,200, you are not taxed. Every dollar over that, up to $37k is taxed at 19 cents. And so on.. Example 1 So as an example, if your income for the year is $25,000 you will be taxed $1292. Working: Here's how it's look if you were doing it in a spreadsheet using the Tax Rates table on the ATO website as a guide:  Example 2 If you income is $50,000, it'd look like this:  Withholding Your employer is obligated to remove the taxable part from your wage each time your paid. They do that using the calculation above.  If at the end of the financial year, the ATO determines that too much as been withheld (ie. you've claimed deductions that've reduce your taxable income to less than what your actual income is), that's when you may be eligible for a refund. If your employer didn't withhold enough or you had income from other sources that haven't been taxed already, then you may actually need to pay rather than expecting a refund. Your question If you earn $18,200 in the year and for some reason your employer did withhold tax from your pay, say $2,000, then yes, you'll get all that $2,000 back as a refund since the Tax Rate for income up to $18,200 is $0.00. If you earned $18,201 and your employer withheld $2000, you'd get $1999.81 back as a refund ($2000 - 19c). You have to pay 19c tax on that $1 over $18,200. "The translation scheme is detailed in IRS Publication 15, ""Employer's Tax Guide"". For the 2010 version, the information is in Section 16 on Page 37. There are two ways that employers can calculate the withheld tax amount: wage bracket and percentage. Alternatively, they can also use one of the methods defined in IRS Publication 15-A. I'll assume the person making $60k/yr with 10 allowances is paid monthly ($5000/period) and married. Using the wage bracket method, the amount withheld for federal taxes would be $83 per pay period. Using the percentage method, it would be $81.23 per pay period. I don't recommend that you use this information to determine how to fill out your W-4. The IRS provides a special online calculator for that purpose, which I have always found quite accurate. Note: ""allowances"" are not the same as ""dependents""; ""allowances"" are a more realistic estimation of your tax deductions, taking into consideration much more than just your dependents." Another thing to remember is that a lot of these one-off police jobs have 4 hour minimum pay requirements, even when they last half an hour (at least in Massachusetts). If you can schedule two jobs such that each one is half an hour, you could work one hour at lunch time and get paid for 8.
