I worked overseas in a combat environment for 5 years, I did not have the taxes taken out, you do have the option to have them taken out. My wife took what we would have paid and put it in an investment fund, I have been on vacation since June and still don't have to worry. The amount that the Govt takes out is a substantial amount, especially on large paychecks. I put the money to work and it really payed for itself, it was a good decision. On the other hand there are guys that DID have the taxes taken out and they were getting tax returned of around 10000. think of the intrest you can get from that after a few years.
