Lynette Tillson makes $4,250.00 monthly. She is married with six children. She pays $645.00 each pay period for medical coverage. She puts in 7.5% of her pay to her 401K retirement plan and her state income tax is 8.15%. According to the federal government she needs to pay $126.00 in federal taxes each pay period. The state government wants her to pay $138.00 in state taxes each pay period. How much money will she bring home in her paycheck?

When you get hired on at a job, you will be asked whether you are single or married and whether you have any children.  Why would that be important?  Because the number of people in your family that you are supporting will affect the amount of taxes (federal, state, Medicare) that are taken out and the amount of the medical insurance premium to cover the entire family.  It does not change the amount a person chooses to have put into a retirement savings plan such as a 401K or the amount of percentage of social security tax and Medicare tax.
