Your take home salary is product of your gross pay, less Social Security tax (which is 6.2%, or $8370 in your case) less Medicare tax (which is .015% or $1958 ) less whatever you tell your employer to withhold for Federal and State tax.
You will fill out a W4 form when you start work in the US , (see example below)
and this will tell your employer how much you want paid towards your Federal tax liability.
You will want to check with your Human Resource people and have them help you decide what is best for you in your individual situation.
I normally claim "Married/0" on my W4, and I always have, even when my kids lived with me, and I have never had a balance due at the end of the year. However, again, you will want HR to help you .
