What is a BAS?

BAS refers to a Business Activity Statement. If your business is registered for Goods and Service Tax (GST), you must submit a BAS form to the Australian Taxation Office (ATO).

Lodging a BAS with the Australian Taxation Office lets them know how much tax you owe or how much tax you need to be refunded for.

A BAS reports on the following aspects of your business:

  • PAYG withholding tax
  • PAYG installments (pay as you go)
  • GST (Goods and service tax)
  • Other applicable taxes your business is required to pay

What is a BAS agent?

A BAS agent is a professional specialising in advising and representing businesses in GST, payroll, and other tax-related matters.

For more information, read our blog covering what is a BAS agent and their required qualifications.

What happens if BAS is late? 

It is imperative to lodge your BAS accurately and on time. If your BAS is late, you may be penalised by the ATO. Always lodge your BAS when it is due.

Are BAS and GST the same?

No. BAS and GST are not the same. A BAS is a business activity statement. GST refers to the goods and service tax that gets applied to the majority of Australian goods. GST must be reported on your BAS.

Do sole traders have to pay BAS?

Yes, sole traders must pay BAS if their gross income is over $75,000.

What happens if the BAS is due on a weekend?

BAS due dates that fall on weekends or public holidays do not have to be lodged and paid until the next business day.

What happens if I make a mistake on my BAS?

If you enter an incorrect amount or accidentally exclude GST from a sale, you’ll need to address these mistakes. This can be done by contacting a tax professional and fixing the mistake by the next due date cycle. Working with a qualified business account can help prevent these BAS mistakes.

Who can lodge BAS?

You can lodge your BAS returns or hire a registered tax professional to lodge your BAS for you. Hiring a business accountant to lodge your BAS ensures compliance, prevents your BAS from getting lodged late, and takes the hassle out of the process.

Are there ways to reduce BAS payments?

If you are making these common BAS mistakes, your business may be paying too much.

Here are some tips on how to reduce BAS payments:

  • Make sure you claim all your GST credits to reduce the amount of GST your business is responsible for paying on the sale of goods and services
  • If your small business has a turnover of $10 million or less, consider paying GST on a cash basis. Paying GST on a cash basis means you pay GST in the BAS period where your business is actively receiving payment from customers. Paying GST on a non-cash basis means you are paying in a BAS period when your business is invoicing customers rather than actually getting payments.
  • Make sure you aren’t accidentally including GST on sales that are GST-exempt (GST-exempt sales often involve medical or health services, food, etc.)

A tax professional can help ensure your business is not making these common BAS mistakes and paying more than necessary.

What happens if I am not able to pay?

Even if you are not able to pay, it is still recommended to lodge your BAS. This proves to the Australian Taxation Office that your business is aware of its tax obligations and working toward compliance.

What are the best BAS tips?

Keep your BAS organised with these tips:

  • Maintain detailed records of all business expenses, wages, invoices, vehicle log books, stock takes, etc.
  • Make sure all sales invoices include GST
  • Make sure all lodgements are up to date with accurate banking details to avoid delaying your BAS refund
  • Use accounting software to maintain accurate records and calculate GST
  • When making your BAS payments to the Australian Taxation Office, use the correct PRN (payment reference number)
  • Consider working with a business accountant to ensure your BAS is accurate and lodged on time
