Get BAS-ready faster with AI BAS

AI BAS (Beta) is an AI‑powered BAS preparation tool that helps get your BAS ready to lodge. It reviews your transactions to detect GST, flag anomalies, find missing documents and explain its suggestions, with the goal of reducing errors and making BAS preparation easier and less stressful.

AI BAS does the review, you make the changes

If AI BAS finds any issues, like the wrong tax code in a transaction, and you'd like to fix it, what you need to do depends on whether you've submitted your BAS.

• If you HAVE submitted your BAS
  
  Work with your advisor to either adjust the next BAS or lodge an amendment for the submitted BAS.
  

• If you HAVE NOT submitted your BAS
  
  While AI BAS is in beta, you’ll need to manually make these changes in MYOB. In a future update this will be automated so you won't need to make these changes yourself. Making these changes ensures your MYOB data matches what you report to the ATO.

AI BAS is currently in beta

This beta is open to sole operators who want to try AI BAS early and help shape its development.

Once you’ve completed your Q4 2025 BAS as you usually would – and before you lodge it, we’d love for you to try AI BAS and compare the results. Did it get the same numbers? Or did it find things you missed? We’d love to know! You can also tell us what worked well, what was unclear, and how we can make AI BAS even easier to use.

Limitations during the beta:

• The beta is only for GST-registered Australian sole traders who use cash accounting and prepare a simple BAS (G1, 1A, 1B).

• You can’t lodge your BAS using AI BAS – it reviews your transactions and generates your BAS figures, ready for BAS preparation.

• AI BAS won’t fix any issues it finds when reviewing your transactions, like a wrong tax code or GST amount. For now, you’ll need to manually update those transactions yourself.

• You can’t currently save your progress when going through the AI BAS review. If you don’t finish the workflow you’ll need to start again from the beginning.

Get started with AI BAS

You’ll use AI BAS to review your transactions for the current quarterly BAS period. You can then compare the values suggested by AI BAS for G1, 1A and 1B with the amounts in your prepared BAS.

AI BAS uses the data in your MYOB file, so make sure your tax codes are set up correctly and you’ve entered all sales and purchases for the BAS period.

Start the review

Access AI BAS from the Reporting menu > BAS reports > Get started.

You’ll see the BAS period that will be reviewed. This will be the current BAS period and can’t be changed.

When you continue, AI BAS reviews your transactions for the BAS period and shows a summary checklist, like this:

Work through the checklist and review the flagged items. Any changes you approve or make, like changes to tax codes or GST amounts, will not be saved or applied to the associated transactions. If you want to make these changes, you’ll need to do it yourself after the review. See Find and update transactions below for details.

Review GST claims with missing documents

The ATO requires a tax invoice for purchases over $82.50 if you want to claim GST.

This part of the review finds all purchases above this amount which include GST and that don't have a tax invoice attached. For each one, choose if you want to claim GST or not. If you're claiming GST you should have the document available for the ATO, and you can upload it into MYOB and attach it to the transaction.

Review transactions

AI BAS has suggested GST codes that are new or different to your original transactions. Review and confirm the right tax code for each.

For each suggestion, click Approve to accept the AI suggestion, or click Edit to make your own changes.

View BAS report

Once you’re done, you’ll see a BAS summary. These figures are based on any changes you approved or made during the review, and you can compare these summary figures to your prepared BAS.

Click Continue to view the changes you need to make manually.

Find and update transactions

At the end of the AI BAS review, the Update your records step shows the list of changes you've approved. You now need to manually make these changes so your records match your BAS.

View or print the list then go to Banking > Bank transactions. Make sure the date filters are set to cover the BAS period.

Now find each transaction you need to edit by searching for the description or amount. Expand the transaction, make the required change (e.g. change the tax code) and click Save.

When you've completed the AI BAS review and updated any required transactions, you can then lodge or amend your BAS via your usual method.

AI helps – but you remain in control

AI BAS generates results from your data using AI, for Simple BAS (G1, 1A, 1B) and cash-based accounts only. AI may generate incorrect information, so you should always review any results and seek professional advice where appropriate. MYOB is not a registered tax agent. You remain responsible for accuracy and compliance in lodging your BAS with the Australian Taxation Office.

If you use an accountant, bookkeeper or BAS agent, AI BAS is built to work with them – not replace them. If your advisor has access to your MYOB file and AI BAS is turned on, they’ll be able to access AI BAS, review the AI suggestions, make adjustments and help you lodge with confidence.

AI BAS does not lodge directly to the ATO

AI BAS currently helps you to prepare ATO‑ready outputs, including GST allocation checks, summary totals and downloadable reports, so you or your BAS agent can enter the figures into the ATO or agent portal (for example via myGov) and lodge as usual.

This keeps you and your advisor in control of the final lodgement step, while AI handles the heavy lifting of BAS preparation in the background.
