Guide to contractor tax: understanding tax obligations as a contractor

If you work as a contractor it’s important to understand your contractor tax obligations to ensure you remain compliant with the requirements of the Australian Taxation Office (ATO). If you work for someone, but you’re not an employee, you’re considered an independent contractor. We’ve put together this guide on contractor tax to help you determine your tax obligations.

What is a contractor?

It’s important to distinguish contractors from regular employees for tax purposes. According to the ATO, an independent contractor can be a sole trader or a person working in their own company, partnership or trust. Therefore, a contractor is a self-employed individual registered as a sole trader. Contractors may also call themselves:

Contractor tax obligations

There are some unique tax obligations for contractors. Let’s take a closer look so that you can better understand how to pay tax as a contractor in Australia.

Does a contractor need an ABN?

Yes, to work as a contractor within Australia, you’ll need an Australian Business Number (ABN). You’ll need it to invoice your clients, otherwise they’re obligated to withhold 47% of your total payment for tax. Your ABN also makes it easy for you to communicate with the government and comply with your tax obligations in your tax return at the end of the financial year (EOFY).

Do you need to pay income tax as a contractor?

Contractors and sole traders are subject to the same income tax rates and tax brackets as resident individuals. Therefore, if you earn more than the tax-free threshold as a contractor – that is, $18,200 – in the financial year, you’re required to pay income tax. Read our guide to income tax or use QuickBooks free income tax calculator to estimate your taxable income as a contractor.

Australia’s tax system is progressive, so the amount of tax you pay will depend on how much you earn. The more you earn, the higher the rate of tax. Read our guide on tax rates and tax brackets in Australia to learn more about the tax rate that applies to you.

How to pay tax as a contractor in Australia

Because you’re not considered an employee, income tax isn’t automatically deducted from your pay on a pay-as-you-go (PAYG) basis. As a contractor you’re obligated to keep aside the amount of tax you expect you’ll have to pay the ATO at the end of the financial year.You’ll need to lodge an income tax return declaring all the income you’ve earned as a contractor and the expenses you have incurred.

To keep things in order, you might consider opening a separate business bank account, where you can transfer the correct proportion of tax owed from each invoice you issue. If you’re working a lot, keeping track of your invoices and tax payable manually throughout the year can be time-consuming. Fortunately, you can simplify the process by investing in accounting software that does the calculations for you. For example, QuickBooks Self-Employed connects straight to your bank account to easily track and categorise business income.

Do contractors need to pay superannuation?

While making superannuation contributions isn’t a legal requirement when you’re self-employed, it is wise to put money aside for your retirement regardless. This will ensure that you will have enough money to live comfortably on when you reach retirement age.

To incentivise low or middle-income contractors to make personal super contributions, the Australian government offers a co-contribution scheme. If you meet certain requirements and make a personal, after-tax contribution, the government will make a co-contribution of up to $500 at the end of each financial year. You don’t need to apply for this scheme as it will be automatically processed when you lodge your tax return.

Do contractors have to pay the Medicare levy?

Since contractors are subject to the same income tax rates and brackets as individual residents, contractors are also required to pay the Medicare levy which is levied at 2% of the taxable income. Depending on the circumstances of your spouse you may be entitled to a reduction or exemption. In addition to the base Medicare levy, contractors may also be subject to the Medicare Levy Surcharge (MLS) if you earn over $93,000 (single taxpayers) or $186,000 (for families) and don’t have private hospital cover.

Do contractors need to register for GST (Goods & Services Tax)?

Contractors who earn over $75,000 annually will need to register for GST. Registering for GST means you will have to charge your clients a 10% GST and will be required to pass this additional income to the ATO. Read our GST registration guide to learn how to register for GST.

Can contractors claim business tax deductions?

If you incur business expenses as a contractor, you may be eligible to claim tax deductions for those expenses. Learn more about tax deductions for sole traders to see what you can claim in your tax return.

QuickBooks has useful resources on tax deduction tips for self-employed contractors. Contractors work across a variety of industries and hybrid roles. Read our tax deduction tips that suit the field you work in to make the most of your deductions at tax time:

Do contractors need to pay their student loans?

Unlike being a permanent employee where your employer makes student loan deductions, contractors take on the responsibility for managing student loan deductions from their personal income. You’ll need to calculate and set aside money to pay your student loan yourself.

Payroll tax and contractors

As a sole trader, you can employ people. If you have employees as a contractor, you may have a contractor payroll tax obligation. Payroll tax is a state or territory tax on the wages you pay as an employer. For example, payments made to contractors are liable for payroll tax in NSW if the contractor is engaged under a “relevant contract” under the Payroll Tax Act 2007 (NSW).

It may be worth having a lawyer or tax professional review your contract with your employee to help you determine if that employee/contractor is engaged under a relevant contract. This will help you determine if you are liable for payroll tax for contractors.
