Deductions & credits

@pk Currently, the standard deduction is not auto subtracted by employer in payroll, which is handled by ADP.

The options provided to me by employer for tax withholding are either W-4 or 8233. If the form 8233 is not applicable in this case since its deduction not exemption, then how to handle the consideration of standard deduction in W-4? 

The current W-4 only says Non-resident Alien at step 4(c). It does not consider this standard deduction available under treaty benefits.
