Single Touch Payroll for WPN holders

Please can MYOB work on single touch payroll for WPN Holders.  I do not have an ABN and cannot apply as not a business.  I employ staff to assist my disabled son and have been paying for MYOB for the past year in order to use STP, however it does not let me set up as I do not have ABN.  Please work on it so when can use STP with an WPN.
