How much of your check each month goes to pay taxes?

It depends. Taxes vary by the amount of pay and dependents. Just like in the civilian world, taxes withheld are different for different people.

Thanks for the answer I appreciate it. Your much nicer than the guys in AF SF.They jump on you for the slightest thing.

My rough guess is that the withholdings for an E-1 will be about 12-20% of pay including Social Security, State and Federal Taxes (the last will be very low with the stimulus bill).
