BAS and the unclaimable-GST report

The BAS report is built directly from your posted transactions and their tax codes — it is the same ledger you've been confirming receipts into, grouped the way the ATO asks for it.

Simpler BAS vs. the full method

Most businesses report under Simpler BAS — GST turnover under $10 million — which only needs three labels: G1 (total sales), 1A (GST on sales), and 1B (GST on purchases). Larger businesses, and input-taxed businesses, use the full seven-label method (G1, G2, G3, G10, G11, 1A, 1B). Snap Apps supports both and defaults to Simpler BAS.

Tax codes, not free-text categories

Every taxable split carries a tax code — GST, CAP (capital purchases), GSTONINCOME, FRE (GST-free), INP (input-taxed), EXP (export), or N-T (not reportable) — each mapped to the BAS label it belongs on. This is the same shape Xero and MYOB use, so a figure here means the same thing your accountant already reads it as.

The rule that decides what you can actually claim

You can only claim a GST credit on a purchase if you hold a valid tax invoice — required once a purchase reaches $82.50 including GST, and the invoice must also show your identity or ABN once it reaches $1,000 including GST. Whether a document meets that bar is decided by the same checks described in Confidence and why a field was flagged, not by you having to remember the thresholds.

The unclaimable-GST report

Label 1B only ever includes GST from purchases backed by a valid tax invoice. Everything else — a receipt missing a supplier ABN above the threshold, one that doesn't show GST separately, a docket that's simply too incomplete — is excluded from what you claim and instead rolled into a visible unclaimable GST figure, with the specific documents that caused it listed so you can chase a proper tax invoice while it's still possible to get one.

Sanity checks on the numbers

The report checks its own arithmetic before you see it: 1A should be about a tenth of G1, and 1B should be about a tenth of your reportable purchases. A BAS period that doesn't reconcile against its own inputs is flagged rather than handed to you looking clean.

What this is not

This report is a tool for preparing your BAS, built from rules the ATO publishes — it is not personalised tax advice, and it doesn't replace a registered BAS or tax agent reviewing your position, particularly for anything unusual (input-taxed supplies, mixed-use assets, GST grouping). See Terms of Service for how this is scoped.
