Where appropriate, support your answer with legislative and judicial authority.
Katie owns a retail store (as a sole trader) that repairs smartphones and laptops. To save costs, Katie often uses substandard equipment to repair such items. One of her employees, being tired of such unethical behavior, quits and threatens to go to the newspapers about Katie’s practices, which would substantially damage the reputation of Katie’s store.
To persuade the ex-employee not to go to the newspaper, Katie gives him $20,000. Katie’s accountant is unsure if this amount is capital or not.
Katie also borrows $100,000 to fund an expansion of her shop. This was for a 10 year loan with borrowing costs of $1,200.
During the year, Katie also lent $1,000 to an established customer (they did not owe the shop any money for the shop’s services). Unfortunately, this money has not been repaid and has been written off.

Required: 

Advise Katie as to:
a). the deductibility of the $20,000, and
b). whether the $1,200 and $1,000 are deductible as specific deductions.
