Where BAS lives

BAS quarters sit on the Business page (/business), under the BAS quarters tab — alongside your business profile and deductions log. There's also a Next BAS tile on the dashboard for any business entity you own, showing the in-progress quarter's estimated owing and days until due.

How figures get computed

The headline change: BAS no longer requires you to re-key the lodged ATO form. We derive it from your tagged transactions, the same way Xero and MYOB do.

When you create a BAS period (entity + start + end dates), Finance Frank scans every transaction for that entity over the period and rolls up:

• G1 total sales — every income transaction (excluding bas_excluded)
• 1A GST collected — includes_gst income lines × 1/11
• 1B GST paid — includes_gst and capital_purchase expense lines × 1/11
• G10 capital purchases — capital_purchase expense lines

You can override any field manually (useful for periods you lodged before you started tagging, or for fields we don't derive — W1 wages, W2 PAYG withheld, 5A PAYG instalment).

Tagging transactions

The GST treatment selector appears on the transaction form, but only when the owning entity is a business (sole trader, company, trust, partnership). Salaried users never see it.

Five values:

• Includes GST — amount has 10% GST baked in. Most invoices and most expenses.
• GST-free — fresh food, exports, basic health. Counts on G1 (sales) but no GST is collected.
• Capital purchase — equipment, vehicles, anything over $1,000 you'd depreciate. Reports separately on G10 in addition to the standard 1B credit.
• BAS excluded — input-taxed sales (residential rent, financial supplies) or non-business spend that shouldn't hit BAS at all.
• — Not GST tagged — — leave blank if the line isn't BAS-relevant.

A small +GST / GST-free / Capital / BAS-excl chip appears on the transaction row so you can see at a glance what's tagged.

What about the lodgement itself?

Finance Frank doesn't lodge your BAS. Your accountant or your accounting software (Xero, MYOB, QuickBooks) does that. Our job is the forecast: how much you'll owe, how much to set aside, when it's due, what's tagged, what isn't.

Frank also flags a BAS due observation in the bubble about 7 days before the deadline.
