BAS Lodgement Dates 2026–27: Complete Guide for Australian Businesses
Staying on top of BAS lodgement dates is a key compliance task for Australian business owners.
No matter your industry—pharmacy, medical, construction, mining, professional services, or a growing SME—missing a BAS deadline can lead to penalties, interest charges, cash flow issues, and extra stress.
According to the Australian Taxation Office, businesses must lodge and pay their BAS by the due date shown on their statement, with quarterly lodgement dates applying to most businesses with GST turnover below $20 million. [ato.gov.au]
Eagle Shared Services supports Australian businesses with bookkeeping, managed payroll, and virtual CFO services to help you stay compliant and improve your financial visibility.
What Is a BAS?
A Business Activity Statement (BAS) lets you report and pay different tax obligations to the Australian Taxation Office, such as GST, PAYG withholding, and PAYG instalments.
The ATO explains BAS reporting requirements in its guide to BAS
Businesses usually report GST monthly, quarterly, or annually, depending on their turnover and reporting category.

If your bookkeeping records are incomplete, these extra weeks often disappear quickly. Our bookkeeping services help ensure your records are up to date long before BAS deadlines arrive.
Why Accurate Bookkeeping Matters
Preparing your BAS doesn’t have to be a last-minute rush every quarter.
Businesses with current bookkeeping records generally benefit from:
- More accurate GST reporting
- Better cash flow visibility
- Reduced compliance risk
- Improved decision-making
- Faster BAS preparation
- Greater confidence during tax time
Many businesses only find bookkeeping problems when it’s time to prepare their BAS. This can affect GST coding, payroll reporting, and overall compliance.

Payroll Reporting and BAS Compliance
Payroll reporting is a key part of BAS compliance, especially for PAYG withholding.
If your business has payroll compliance issues, you might run into reporting errors that impact both your BAS and payroll requirements.
Our Managed Payroll Services and Payroll Compliance Reviews help you lower risk, make sure your employees are paid correctly, and meet all legal requirements.
A lot of business owners don’t notice cash flow problems until it’s time to pay their BAS.
Knowing how your business is performing before BAS time can help you avoid unexpected issues.
Our virtual CFO services offer financial reporting, budgeting, forecasting, cash flow management, and business insights to help you make better decisions.
