Understanding BAS and IAS

A Business Activity Statement (BAS) is used to report and pay GST, PAYG withholding, PAYG instalments and other relevant taxes to the ATO. An Instalment Activity Statement (IAS) is generally required when a business needs to report PAYG withholding or instalments but is not reporting GST for that period.

While the forms themselves may appear straightforward, the accuracy of the underlying bookkeeping is critical. Maximum Pro Bookkeeping reviews and reconciles your accounts before lodgement. We help to ensure that every figure submitted is supported by accurate records.

BAS Lodgement Services

Maximum Pro Bookkeeping provides comprehensive BAS lodgement services designed to remove the stress from compliance. We carefully assess your accounts, calculate GST obligations, review PAYG withholding and instalments, and identify any discrepancies before submission. Once finalised, your BAS is lodged electronically with the ATO within the required timeframe.

Working with a registered BAS agent Australia means you benefit from expert oversight and a clear understanding. Rather than rushing to meet deadlines, you gain structured, consistent compliance support. At Maximum Pro Bookkeeping our BAS lodgement services are a mechanism for making our clients feel confident and reassured financially.
