You still pay Federal and State Income Taxes, if your home state has one, plus Social Security and Medicaid Tax. Just a quick calculation says your total Federal Tax burden is about $403 a month at your income level. Then deduct SGLI and State taxes, that sounds about right for 1/2 months pay.

Sounds like you're still in Basic training. During basic training, all services receive a reduced pay. E1 is about 1680 a month, meaning 840 every pay. Take away taxes state and federal taxes plus SGLI, and that's about 560.

Talk to your team leader about turning in a pay inquiry and les to your S1 to figure it out if your leadership doesnt know.

But your LES says it all. Talk to your Squad leader, platoon Sargent, S-1 and so on following the chain until the problem is solved
