Contracts are exempt if a person provides you with the same or similar services for a total of not more than 90 days in a financial year. On the 91st day, the entire period becomes liable for payroll tax.
Unlike the 180-day exemption, this exemption applies to the individual who is providing the service and focuses on the number of days an individual works for you.
A day is 1 calendar day, from midnight to midnight. Any length of time worked in a day will count as a whole day.
'Employee' and 'contractor' may have different meanings for payroll tax purposes from what you might expect.
Please review the meanings of employees and contractors to determine which definition applies to each employment arrangement. If the contractor has an employee/employer relationship with the principal, the contractor provisions will not apply.
Example 1
A contract security officer works for Night Ltd for 80 night shifts (on non-consecutive days) in total for a financial year. The security officer works from 10pm to 6am in each shift. This means one shift is considered to be 2 days. Therefore, the security officer has worked for 160 days. All Night Ltd’s payments to him are liable for payroll tax.
Example 2
You contract Bob as a concreter for 30 days and to drive a cement mixer for another 75 days. Because Bob provides you with similar services for a total of 105 days, any amounts paid to him are taxable.
