Child support deductions are setup in Wagemaster as allowance deductions, untaxed and not included in super calculation.
The below screen shot is an example. Depending on the amount to be deducted, the allowance can be set up with a predetermined amount each pay, as a percentage, or left as zero if the amount needs to be calculated each time.
As an allowance deduction, payment can be directed automatically to a 3rd party bank account. This is done from the Bank tab within the allowance, after the allowance has been setup. Bank details would be provided from the relevant government agency.
