Australian GST BAS support

Australian GST BAS workpapers for Australian and New Zealand accounting professionals

Turn a transaction export into review support for the core Simpler BAS GST labels: G1 total sales, 1A GST on sales, 1B GST on purchases, net GST, and row-level exceptions.

How it works

1. Step 1

   Upload the transaction export

   Attach one Australian sales and purchases export as CSV or XLSX.

2. Step 2

   Core BAS labels calculate

   Deterministic logic classifies rows and prepares G1, 1A, 1B, and net GST review totals.

3. Step 3

   Review before transfer

   Work the exception list and confirm unmapped labels or adjustments before using any figure on a BAS.

What you get

• G1 / 1A / 1B summary
• Prepared workbook
• Exception list

Frequently asked questions

Does it lodge the BAS?

No. It creates a review workpaper for the core GST labels; a qualified professional confirms the treatment and lodges through the normal ATO process.

Does it prepare every BAS label?

No. The first version focuses on G1, 1A, and 1B. Other GST, PAYG, WET, LCT, and fuel-tax-credit labels require separate review.

Is the output generated by an LLM?

No. The workpaper numbers are computed by deterministic spreadsheet logic — the same inputs always produce the same outputs. AI is only used to route your request and explain the results, so every figure is traceable to source rows.
