When starting or growing a business in Australia, understanding and setting up GST (Goods and Services Tax) and PAYG (Pay As You Go) Withholding is crucial. These are two of the most important tax obligations that Australian businesses need to stay compliant with, and failing to set them up correctly can lead to financial penalties or a strained relationship with the ATO. Fortunately, with a few simple steps, you can easily set up both GST and PAYG for your business.
What Is GST, and Why Should You Register for It?
GST is a 10% tax on most goods and services sold in Australia. If your business turnover is $75,000 or more (or $150,000 for non-profit organizations), you must register for GST with the Australian Taxation Office (ATO). Once registered, you will charge GST on your sales and can also claim GST credits on the goods and services you purchase for your business.
How to Set Up GST for Your Business
Determine Eligibility:
If your business's annual turnover exceeds the GST threshold ($75,000), registration is mandatory.
If your turnover is less than $75,000, you can still choose to register voluntarily if you think it will benefit your business.
Register with the ATO:
Register online through the Australian Business Register (ABR) or through your accountant.
You’ll need an ABN (Australian Business Number) to register for GST, so make sure you have that ready.
Once registered, you will receive a GST registration confirmation from the ATO.
Start Issuing Tax Invoices:
Once registered, you must issue tax invoices for your sales, which should include the GST amount.
Remember, your business will need to remit the GST to the ATO when you lodge your BAS (Business Activity Statement).
What Is PAYG Withholding, and Why Is It Important?
PAYG Withholding is a system where you withhold tax from your employees' wages and send it to the ATO on their behalf. This ensures that employees pay their income tax gradually throughout the year, instead of having to pay a lump sum at the end of the year.
As a business owner, if you have employees, contractors, or directors on payroll, you must register for PAYG Withholding.
How to Set Up PAYG Withholding for Your Business
Register for PAYG Withholding:
This can be done when registering for your ABN or GST. If you’re not already registered, you can apply for PAYG withholding through the ATO's online portal.
You will need to confirm the number of employees or contractors you’ll be withholding tax for.
Calculate Your Employee's Taxable Income:
To determine how much tax to withhold, use the ATO’s tax tables to calculate the correct amount for each employee.
You can also use payroll software to automate these calculations for accuracy and efficiency.
Set Up PAYG Deductions:
Deduct the required amount of PAYG from your employees’ wages each pay cycle.
Submit your withheld tax to the ATO via your BAS lodgements. This is generally done quarterly or annually, depending on your business's size and turnover.
Provide PAYG Payment Summaries:
At the end of the financial year, issue your employees with a PAYG Payment Summary (also known as a group certificate) to show how much tax has been withheld.
Common Mistakes to Avoid When Setting Up GST & PAYG
Not Registering Early Enough:
Failing to register for GST when your business hits the threshold can result in fines and missed tax credits.
Incorrect Invoicing:
Make sure that GST is properly applied to your invoices and that you have all the required information for your BAS.
Underestimating PAYG Withholding Obligations:
It’s essential to calculate the correct withholding amount for each employee, so they don’t end up owing large amounts at the end of the financial year.
Missing BAS Lodgement Deadlines:
Late BAS lodgements can result in penalties, so always stay on top of your filing schedule.
How to Stay Compliant with GST & PAYG
Use Accounting Software: Tools like Xero, MYOB, and QuickBooks make managing GST and PAYG a breeze by automating calculations and generating reports.
Regularly Review Your Finances: Stay on top of your accounts and lodge your BAS on time. Keep track of all tax liabilities and ensure you have the necessary documentation.
Seek Professional Help: If you're unsure or want to ensure you're meeting your obligations, it’s always a good idea to consult a professional accountant.
