Effective January 1, 2007, the Internal Revenue Service requires employers to add a specified amount to the wages of any non-resident alien employee for the purpose of calculating income tax withholding.
Payroll period Additional amount
Weekly $51
Biweekly $102
Semimonthly $110
Monthly $221
Quarterly $663
Semiannually $1,325
Annually $2,650
This means if you have an F-1 or an H1-B Visa, we are instructed to set you up as Single with one exemption and add the amount above that coincides with your pay period to tax you correctly. You will not be able to change your withholding as long as this is in effect; this means we will no longer accept any new W4 forms.
