UST_ADD_TAX_PER_PERIOD is an optional 18 digit numeric field which indicates the amount of additional tax to be taken each pay period.
If the employee does not have enough taxable earnings this amount will only be taken if the additional tax option is set to 'always’ in the Payroll Information form and the pay is a ‘Regular Pay’ pay category. If State Tax Method = Annualized +%, then this field contains the percentage that will be apply to federal earnings and treats as additional tax. (e.g. 5%, enter as 5). If State Tax Method = Annualized + Amount, then this field contains a per pay period additional tax amount.
