There are many companies that provide the tax advantage program (where a portion of you're hourly wage is given to you tax free because you have a permanent residence. Some companies do - and I am not sure how it actually works - as a "per diem").
I work with RN Network. The way they do it is, ex:
Pay rate $30/hr
Tax advantage: $8.75 {for the first 24 hours/week ($210/week)}
Sample pay: 72 hour/pay period - 2 weeks
48 hours x $21.25 (tax advantage)= $1020
24 hours x $30 = $720
Any OT over 40 hours/week= paid at $60/hr
All taxes based on this total.
THEN, $420 is added back into your pay.
It does decrease the amount that is paid into SS, though. So depending on if you want extra money now, or later........
