- A draft you check. You or your accountant lodges it, not us.
What it finds
1B is the GST you paid on business purchases: it comes off what you owe. Bought something personal? Mark it personal and it stays out of your BAS.
How it goes
Add one file
A receipt or a statement you already have.
See what it found
Date, total, GST and the BAS line it goes on.
Add the rest when you're ready
The whole quarter becomes a draft with G1, 1A and 1B. You check it; you or your accountant lodge.
Downloading the full draft (PDF or Excel) needs a free sign-in with your email. Trying it doesn't.

Quick answers
Is it really free?
Yes. No card and no sign-up to start. To download your BAS draft (PDF) and Excel report you sign in with your email, which is also free. AI sorting (optional, with the free sign-in) is free up to 300 lines a month. No subscription, nothing to cancel, and it's not a trial. If we add a paid extra later, it will be optional and priced on the site first.
Where do my files go?
Nowhere. YellowBAS reads your statements and receipts right here in your browser. They aren't uploaded to our server or anyone else's. If you choose AI sorting, only shop names are sent, never your files, amounts or account numbers.
Which banks does it read?
CommBank, NAB, Westpac, ANZ, St.George, BankSA, Bankwest, Bendigo, Suncorp, ING, BOQ, Macquarie and more, plus Square, Stripe, PayPal and Shopify reports. PDF, CSV, OFX or QIF.
Does it lodge my BAS?
No. It makes a draft with G1, 1A and 1B. You check it, then you lodge it with the ATO yourself or your registered agent does.
What if a figure is wrong?
Every figure links back to the bank line or receipt it came from, so you can see why it's there and change it before you use the draft.
