From the Contacts tab in the Opto ribbon, select Tax Codes from the Data Set drop-down menu, as shown below.

Next, open MYOB, create a code and copy the information into the Opto fields as it is in MYOB – the most important fields are the “Tax Export” and “Tax Rate” circled below. These fields MUST match MYOB to export correctly.

Press <F9> to save, continue to create tax codes as necessary.
