Aggregate − No Tax else Percent

When supplemental wages are paid separately from normal wages, withholding depends on whether tax was withheld on the employee's current payment of normal wages, if any, or on previous on-cycle payments (in the same pay group).

If no tax was withheld on either condition, calculate tax on supplemental wages using the Aggregate Method described previously for supplemental wages paid separately.

If tax was withheld on either condition, calculate tax using a flat percent rate as specified by the state, without regard for tax status or allowances.

Example

A Connecticut employee, single with one allowance, is paid a $1000 bonus as a separate check. The employee's last previous on-cycle normal paycheck in the current year was for normal weekly earnings of $500, from which $10.92 Connecticut tax was withheld. Using the flat rate of 4.5 percent specified by Connecticut, calculate the Connecticut tax to be withheld on the bonus:

4.5% X $1000 = $45
