Field or Control |

FICA Method (Federal Insurance Contributions Act method) |
Indicates the method that the system uses to calculate FICA credits. |

Supplemental Method
Field or Control |
Description |
---|---|
Paid with Regular Wages and Separate Payment |
Indicates the method by which the system determines the tax for supplemental income. Many states have a supplemental method for the Paid with Regular Wages payment method that differs from the supplemental method specified for the Separate Payment payment method. If either of these fields has a value of Multiple Rates, the Special Rate field becomes available. |
Supplemental Rate |
Indicates the percentage by which the system multiplies the taxable gross when calculating tax for supplemental income. This field applies only to the payment methods with a supplemental method of Aggregate-No Tax else Percent or Percent of Taxable Gross. For example, for the state of Colorado, the supplemental method specified in the Separate Payment field is Percent of Taxable Gross and the supplemental rate is 4.63. That means that for supplemental payments, such as bonuses, that are paid separately from regular wages, the system multiplies the taxable gross of the supplemental payment by 4.63 percent to determine the state tax. |
Special Rate |
Indicates the percentage by which the system multiplies special supplementary income, such as stock. This field applies only to the payment method with a supplemental method of Multiple Rates. |
