BAS Record Keeping and Lodgement Dates for Australian Businesses

Businesses registered for GST in Australia must lodge a Business Activity Statement (BAS) either monthly or quarterly. Accurate BAS record keeping is essential to ensure your GST reporting is correct and compliant with Australian Taxation Office (ATO) requirements.

Maintaining organised records throughout the quarter makes BAS preparation easier and helps avoid errors when lodging your statement.

 

What Records Do Businesses Need to Keep for BAS?

The ATO requires businesses to keep records that support the figures reported in their BAS.

Key records include:

• Tax invoices for sales and purchases
• Receipts and proof of business expenses
• Records of GST collected and GST paid
• Bank statements and accounting reports
• Payroll and employee payment records
• Documentation supporting BAS adjustments

Keeping these records organised throughout the reporting period helps ensure your BAS lodgement is accurate and compliant with GST rules.
