Jessica is a financial accountant working in the finance department of an engineering consulting firm. The firm recently reviewed their internal operations and decided that the finance department should be outsourced to independent third-party contractors, with existing staff being made redundant. The firm was however keen to retain Jessica due to her intricate industry knowledge. To achieve this, the following steps were undertaken:

1. Jessica incorporated a company with the registered name of Jessica's Accountancy Services Pty Ltd (JAS). Jessica is the sole director and shareholder of JAS.
2. The firm and JAS entered into a "Services Contract" for the provision of accountancy services for an annual sum of $130,000. This annual sum is equivalent to what would have been Jessica's annual salary.

Jessica is required to attend the premises of the engineering firm during normal business hours each working day. A bungalow located at the rear of Jessica's home, which is separate to her house, is dedicated to Jessica to undertake any JAS business matters. JAS also employs her son at an annual salary of $30,000 to undertake administrative tasks.

Advise Jessica and JAS of the tax implications of the annual sum of $130,000 and the salary of $30,000 paid to her son.
