Tax withholding is based on all wages paid during a week; therefore, if you receive multiple payments dated during the same week ending, your tax withholdings will be based on the accumulated wages paid during that entire week.

For example, each subsequent pay after the initial pay in that week will take into account all prior amounts paid. Taxes will be recalculated to ensure that tax withholding obligations are fulfilled based on the total wages PAID in a pay period.

Any supplemental payments, such as any type of bonus or commission, will be taxed at the IRS supplemental rate of 22%.
