Step 2 · Review

Answer a few questions, then check the list.

Most lines sort themselves: fuel, tools, phone, supplies. For the few it can't be sure about, YellowBAS asks you one simple question at a time. Then you see the whole quarter grouped by category, biggest first, with the GST under each amount.

You do

  1. Tap Business, Personal, Both or Not sure.
  2. If it's business, tap what it was (for example Materials).
  3. Press Save and next.
  4. Open a category and change anything that looks wrong. Press Always so it's right next quarter too.

YellowBAS does

  • Works out the GST for every line.
  • Keeps personal spending out of your BAS.
  • "Not sure" lines go in a list for your accountant.
  • Matches receipts to their bank lines and adds up the totals.

Question 1 of 5: a Bunnings purchase, with Business, Personal, Both and Not sure buttons, and a Sort with AI box for shops YellowBAS doesn't know
Only 5 questions for 32 lines. A supermarket shop is a typical question: groceries for home, or supplies for work?

Don't know the answer?Tap Not sure. You don't have to know everything: those lines go on a list for your accountant.

Step 3 · BAS & export

Download your BAS numbers.

You get the numbers the BAS form asks for, each one explained in plain English, and an Excel report of your expenses. Lodge it yourself, or send it to your accountant.

You do

  1. Check the numbers on the page.
  2. Press Download Excel report (and the PDF draft if you like).
  3. Lodge with the ATO yourself, or email it to your accountant.

You get

  • Your total sales and the GST on them.
  • The GST you can claim back.
  • What you owe the ATO, or get back.
  • Each with its box code (G1, 1A, 1B…) for your accountant.

The BAS draft: each box says where its number came from, and the checks on the right show what to look at.
Good to knowYellowBAS prepares a draft. It doesn't lodge for you and isn't a tax agent. You or your accountant lodge the BAS.

Next quarter is even quicker.

It remembersEvery answer you saved with Always is used again. Fewer questions each quarter.
Your files stay with youStatements and receipts are read on your device. Phone photos travel encrypted to your computer. Only if you press Sort with AI or Fix with AI does some text go out: shop names, or the words read from one receipt with card numbers and names taken out. Never your files.
Easy to share the jobSave your work and carry on later, on another computer, or hand it to whoever helps with the books.

Questions people ask first

I'm not an accountant. Can I really do this?

Yes. That's who it's for. You only answer everyday questions like "was this for the business or for home?". Words like G1 and 1B are explained right next to each number.

What if I get an answer wrong?

Change it any time before you download: open the list and pick another column. Nothing is sent to the ATO by YellowBAS. If you're unsure, tap Not sure and it's flagged for your accountant.

Which banks work?

All the big Australian banks and most others: CommBank, Westpac, ANZ, NAB, ING, Bendigo, Suncorp, Macquarie, plus PayPal, Wise and Revolut. CSV is best; PDF statements work too.

What is Sort with AI?

For shops YellowBAS has never seen, press Sort with AI and it suggests a column for each. Only the shop names are sent, never amounts or files, and you check each suggestion before it counts. Free up to 300 a month once you sign in.

How much does it cost?

It's free: no credit card, and no sign-up needed to start. You sign in (also free, just your email) to download your BAS draft and Excel report, and for AI sorting, which is free up to 300 lines a month. The current version stays free for one business (one ABN). Coming soon: packages with extra features, and versions for accounting practices and BAS agents.
