Net Paycheck
Sunday, July 29th, 2007Eldon writes: I graduated from college last May and have been trying to evaluate several job offers that I have. I’d like to estimate how much money I will be paying in taxes so that I can determine what my actual take home pay will be at each job, and so that I can also determine how much I’ll be able to save, how much I can budget to spend on housing, etc. I’m having difficulty finding a definite answer to a very basic question.
Here is my question: While trying to estimate my taxes I found the tax rate tables, which show marginal federal tax rates, with which I was able to estimate my tax rates. But do these rate tables include payroll taxes like medicare and social security? In the past I know that those were withheld from my paycheck but were not refunded when I filed at the year’s end. For instance, using the tax rate tables, if I plug in an income of $78000, my tax will be $15,107 plus %28 of $3800 (1064), for a total federal tax of $16,171. This is a rate of only about 21%. But when I actually have to pay taxes, will I be paying 16,171 plus payroll taxes (which I read somewhere are like 7.5%), so that my actual rate would be around 28-29%? Or does this number include payroll taxes?
Sorry for such a basic question - like I said, I’ve never had to worry about taxes and don’t want to make a stupid mistake and screw up my tax estimate. Thanks, Eldon
My reply:Hello Eldon! Thank you for visiting my site!
I have never understood why Basic Finance (a class that would teach you how to determine your net paycheck, how to balance your checkbooks, how to reconcile your bank statement, how to reconcile your credit card statements, how to make a budget, etc.) is not a high school requirement, for in such a class you would have learned the answer to your question, one which every high school graduate should know and understand. Since they don’t, please don’t feel bad that you do not know the answer to this question, as it’s not as simple as it sounds.
First, the tax rate tables that you found do NOT include Social Security or Medicare taxes. Assuming these tables were payroll tax tables, they ESTIMATE the amount of Federal income taxes that you will probably owe at the end of the year.
Second, Social Security is withheld at a rate of 6.2% of your gross income up until your gross income reaches $97,500 in 2007. Medicare is withheld at a rate of 1.45% of your gross wages, regardless of how high your wages are for 2007. Unless you have multiple employers and combined your reach over $97,500, you never receive a refund of these taxes.
The amount of your net check, or take home pay, is rarely equivalent to your annual take home pay after you file your Federal income tax return. The reason is that the amounts taken from your paycheck (Federal taxes, Medicare, Social Security, and other potential withholdings like State withholding, Flexible Spending Accounts, Medical Premiums, etc.) do not directly correspond to the income tax return which you are required to file at the end of the year. If you know what all your deductions will be, and their amounts, the easiest way to compute your tax home pay would be to plug all those numbers into a payroll calculator. You can find a free one at PaycheckCity.com, but remember, that is just an estimate. You may owe more Federal income taxes when you file your tax return or you may get a refund.
Depending on many factors, your taxable income, as determined on your annual income tax return, is computed based on your filing status, number of exemptions, standard or itemized deductions and other potential adjustments to determine your taxable income. Your taxable income is then used to determine the potential amount of federal income taxes you will owe. This amount is then adjusted for items such as AMT and tax credits. You may find it very useful to review the following IRS publications:
- IRS Publication 17: an introduction to federal income taxes
- IRS Publication 15-A: payroll withholding tables.
