BAS Returns – Expert Help Without the Hassle
Staying on top of your BAS obligations is essential for keeping your business compliant with the ATO—but it doesn’t have to be stressful. At Tax Logic, our experienced Sydney-based tax agents take care of your BAS preparation and lodgement, so you can focus on running your business.
Whether you're registered for GST, PAYG withholding, or Fringe Benefits Tax (FBT), we’ll guide you through the process and handle the details. Our goal is to make BAS simple, accurate, and on time—every time.
What is a BAS Return?
A Business Activity Statement (BAS) is a key document that businesses use to report their Goods and Services Tax (GST), PAYG (Pay As You Go) instalments, and other tax obligations to the Australian Taxation Office (ATO). BAS is typically lodged monthly, quarterly, or annually, depending on the size and type of your business and includes the following categories:
- GST (Goods & Services Tax)
- PAYG Tax Withholding for Wages (Pay As You Go)
- PAYG Tax Instalments (Pay As You Go)
- FBT Instalments (Fringe Benefits Tax)
- Wine Equalisation Tax
- Luxury Car Tax
- Deferred Company Tax Instalment
- Fuel Tax Credit
Filing your BAS accurately is critical not just for avoiding penalties, but also for ensuring that you claim all possible tax credits, such as the GST on business expenses.
Things you should know about GST & BAS:
- Registration for GST is compulsory for businesses with an annual turnover of $75,000 or more
- You must have an ABN to claim GST back on any business purchases you make
- The size of your business will determine whether you need to lodge your BAS Return annually, quarterly or monthly.
- Businesses with an annual turnover less than $20 million may lodge their BAS returns quarterly.
- You can account for GST on a cash basis where your annual turnover is less than $2 million

BAS Lodgement Deadlines in Australia
BAS returns are generally due on the 28th of the month following the end of the quarter. If you are required to lodge monthly, your BAS will be due on the 21st of the following month. However, deadlines may vary depending on your business structure, GST registration and whether you lodge via a Tax Agent.
Missed deadlines can result in penalties, so it’s vital to lodge on time.
Here’s a clear table of BAS lodgement due dates for both monthly and quarterly reporting cycles for the 2025–2026 financial year, based on the latest ATO and tax agent guidance:
