Business Activity Statements prepared from fully reconciled data.
BAS preparation from fully reconciled, current financial data ensures every figure is verifiable, defensible, and audit-ready. We calculate GST, PAYG, and other obligations from your actual records, then provide the BAS ready for your review and lodgement.
The short answer
BAS preparation is the work of calculating the figures for a Business Activity Statement — GST collected and paid, PAYG, and other ATO obligations — from a business's reconciled financial records, ready for review before lodgement. It’s one function of BAS & Tax Compliance within your Finance Hub — part of a connected back office.
The Challenge
Common problems we solve
BAS is prepared from books that are not fully reconciled, so the figures are really estimates
There is no clear workpaper trail behind the numbers if the ATO asks how they were derived
Errors only surface after lodgement, requiring amendments that attract questions
Legitimate input tax credits are missed because the records were not in order at BAS time
What's Included
Here's what you receive
Reconciled Starting Point
BAS prepared only once your financial data is reconciled to period-end, so figures rest on verified records rather than estimates.
GST Calculation
GST on sales and input tax credits on purchases calculated from your actual transactions, with non-claimable items excluded.
PAYG & Other Obligations
PAYG withholding, instalments, and any other applicable items identified and calculated alongside GST.
Supporting Workpapers
Each figure backed by workpapers tracing to source records, so the statement is defensible if the ATO asks.
Draft for Review
A draft BAS prepared for you to review and approve, with corrections made before anything is lodged.
Amendment-Ready Records
If an error in a prior period is identified, the impact is calculated and an amended BAS can be prepared.
Why It Matters
How it works
A Business Activity Statement is only as reliable as the data behind it. When a BAS is prepared from books that have not been fully reconciled, the figures are essentially estimates—and estimates are what lead to amendments, ATO queries, and the interest and penalties that follow. We prepare your BAS from reconciled, current financial data, so every figure traces back to an actual, verifiable record. GST on sales and purchases, PAYG obligations, and any other items are calculated from your books rather than approximated. The result is a BAS you can lodge with confidence. Each figure is supported, the calculations are defensible if the ATO asks, and the whole statement comes to you for review before anything is submitted. Because the underlying data is reconciled, the chance of needing a later amendment is greatly reduced.
