When selecting payg employment it would be good to add the following fields as they are all required in AOL - HR contact name and number, employer address. Job Title is a redundant field as i haven't used it in AOL only role. Unless its a lender which i haven't used before that requires it.
When selecting self employed, the field "Basis" is pretty redundant but its needed for AOL so i guess its always full time, for our records also have a field to Add ABN and ACN, especially useful when there is a trust and corporate trustees as they are especially hard to find on ABN search.
Rename the field Employer name to, company or business name. Income fields for self employed needs more options, depreciation / interest add backs / director fees / director salary / trust distribution etc. There is only 3 there at the moment which are more relevant to being PAYG. And when selecting trust have additional fields to add Trust and Trustee names
