You should see the following on the stub of your paycheck:Federal Income Tax is taken out (u201cwithheldu201d) at a rate calculated from what you put on your W-4. It is important to realize that this is not the end of the story, itu2019s just a guess at what your actual taxes will be.At the end of the year, you will get a statement (a u201cW-2u201d) showing how much you paid. At this point, you fill out Form 1040 (or 1040A, or 1040EZ) to figure out your actual taxes. (The deadline to fill this out is April 15) The difference is refunded to you (or paid by you.)I wish I could tell you the rate of income tax. Unfortunately, the calculation process is so complex that thereu2019s no way to put a number on it without knowing a lot more about you. A good guess is the u201cmedian effective rateu201d, which is 10% of your income.State Income Tax is done similarly to Federal Income Tax. The withholding rate will again depend on your W-4 information. Different states have different rates of income taxes. Just like with your federal taxes, you need to fill out a form at the end of the year for your state tax.Social Security Tax is taken out at a rate of 6.2%. Your employer also pays 6.2% of your wages in Social Security Tax. (You wonu2019t ever see this amount, but itu2019s still there, without it, your employer might give you a 6.2% raise.) You donu2019t have to file anything or get any refund.Medicare Tax works the same as Social Social Security Tax, but the rate is 1.45%.
