Contractor Payrolling

Everything You Need to Know About Contractor Payrolling

Right now, contingent workers make up around one third of the workforce in Australia and New Zealand. What’s more, 62% of business leaders predict that their workforce will incorporate more contingent staff in the future, and many experts predict the workforce will be 50% contingent by 2028.

In today’s workforces, contingent work has grown larger than retail staff, temporary reception roles, or call centre workers. The modern contingent worker is often a highly skilled professional that chooses to work for a variety of companies depending on their interest and work schedule.

Because of the rapid rise of contingent workers, organisations need to have a comprehensive understanding and capability around accurately and efficiently paying them. In the article, we answer some of the biggest questions regarding contingent worker payroll.

How are contractors paid?

Contingent workers are prolific in most industries in a variety of role types, from project managers, developers, engineers and analysts. Typically, they’re paid either through a time and materials arrangement, or milestone based. We’ve outlined these below:

  • Time and materials – these contractors are paid on an hourly or daily rate.
  • Milestone – otherwise called outcome-based, these contractors are paid an agreed rate at the completion of a project.

Many organisations employ contingent workers under a statement of work (SOW) arrangement. A SOW document outlines the contractual arrangement and specifies the required outcome for the contingent worker to complete.

As we’ve outlined in our risk diagnostic tool, some companies employ SOW contractors under time and materials – which is considered as sham contracting. In these circumstances, the company pays an hourly or daily rate, with no visibility on preferred supplier margin or specified outcomes. This leads to inflated costs – often 30% higher than traditional contingent workers.

Contractor payroll taxDo you pay payroll tax on contractors?

Organisations pay payroll tax to State Governments based on the wages of their workers. But not all contractor wages are considered taxable wages. If a contractor falls under one of these nine exceptions, employers do not have to pay payroll tax.

  • If the contractor owns and drives a vehicle for their job.
  • If the contractor only sells insurance.
  • If the contractor is a door-to-door seller.
  • If the contractor provides services to one principal for 90 days or less in a year.
  • If the contractor engages others to do all or part of the work.
  • If the contractor’s labour is secondary to them supplying materials or equipment.
  • The services provided are not usually required in the principal’s ongoing business, and the contractor provides these services to a range of clients.
  • The services are usually required less than 180 days in a year.
  • The services are approved by The Commissioner as exempt.

Although the payroll tax rate varies depending on the state, most provisions in the Payroll Tax Act are similar to one another across Australia.

There are penalties for those that don’t pay their contractors’ payroll tax on time. Employers will need to pay interest on any payments outstanding, and potentially a flat penalty percentage depending on the jurisdiction.

Do I need to make superannuation contributions to contractors?

Organisations need to make super contributions if you’re engaging them mostly for their labour. This means:

  • You’re paying them wholly for their skills.
  • They’re performing the work personally.
  • You’re paying them for hours worked, not to achieve a result.

For contractors that are set up as a company (i.e., Pty Ltd), organisations do not need to pay superannuation.

Recently, the government has introduced legislation to parliament to ensure employers are setting up workers with their own default superannuation fund, not the preferred employer fund. If passed, employers must pay employees into a ‘stapled fund’ (either the last fund that contributions were paid into, or the fund with the largest balance) rather than an employer’s default fund.

CXC has implemented changes to our process in advance of this law, ensuring that contingent workers are provided with a complete view of their superannuation, as well as the opportunity to automatically find past superannuation accounts and consolidate these during their onboarding process.

Contractor benefitsDo I need to provide benefits to my contingent workers?

Many employers neglect to include contractors in the benefit programs they provide to permanent workers. This is a significant missed opportunity to increase the engagement, productivity and wellbeing of your extended workforce.

The cost of replacing permanent workers is around 30% of their annual salary. Although this cost isn’t as high for contractors, organisations can save significant amounts if a contractor decides to stay with the company, either through redeployment or working on a different project. Contractor benefit programs can help attract and retain these contractors.

In addition to process and experience improvements for all stakeholders through CXC’s model, we provide a dedicated contingent worker care program. This program is focused on treating contingent workers like the professionals they are, giving them access to a diverse package of benefits. This differentiates our service from recruitment-focused providers and strengthens your brand among professional level contingent workers.

Payroll systemWhat system should you use to payroll contractors?

Some organisations payroll their contingent workforce through their permanent employee systems and processes. Others use vendor management system (VMS) technology, such as Beeline or SAP Fieldglass.

Regardless of the solution you choose to adopt, organisations need to be mindful of:

  • Ensuring payment accuracy.
  • Gaining complete visibility of the workforce through analytics.
  • Ensuring payroll technology is compliant to all relevant laws.
