AI BAS turns BAS preparation into ongoing tasks throughout the quarter, so you’re not left with a last-minute clean-up.
It surfaces missing documents, GST issues and uncategorised transactions as they arise. Your dashboard shows your BAS readiness percentage and what needs your attention.
When you approve an AI BAS suggestion, it updates your books automatically. You review the result and lodge your BAS through your usual method.
How AI BAS works
AI BAS is available any time you open your MYOB Business. When you sign in, your dashboard shows any AI BAS items that need review, such as an incorrect tax code, a missing document, or transactions from the BAS period that haven't been matched or categorised.
You can click a shortcut in an AI BAS card to open AI BAS where you can review the suggestion, assign a category or make your own changes. When your BAS is ready to be lodged, you'll see a message letting you know.
Key points:
AI helps, but you stay in control. You don’t have to accept AI BAS suggestions.
Rejecting a suggestion changes nothing. Your transaction stays as-is in your books.
You can edit suggestions you disagree with. Update the transaction yourself instead.
AI BAS doesn’t lodge with the ATO. You do, or your advisor does.
AI BAS is a Premium Feature
To start using AI BAS, you need to add it to your MYOB account in My Account as a Premium Feature (what are Premium Features?). This means you pay an additional charge on top of your MYOB Business subscription. You can see details of this charge when you preview your AI BAS plan in My Account.
Once you've added AI BAS, you’ll see it when you open MYOB Business and can start using it straight away.
Part of the AI BAS Beta? You can continue using AI BAS, without any additional cost, for a limited time. After this, you’ll need to add AI BAS to your subscription as a Premium Feature.
To add AI BAS
Only the Primary Contact or Billing Contact on the MYOB account can add AI BAS.
Log in to My Account and go to Manage my product.
Click Manage my subscription.
On the Manage subscription page, Premium features section, click Add AI BAS.
On the review page, review your subscription changes.
Click Add AI BAS to subscription.
The Manage subscription page is updated to show you have activated AI BAS.
The dashboard shows you what needs reviewing
Any time you log in to MYOB, you'll see the dashboard. It's updated continuously as your books change, and it's your starting point for keeping on top of BAS-related tasks.
What you'll see in your dashboard
Log in to MYOB Business to see your dashboard. It shows ranked cards for things that need your attention across AI BAS, banking, sales and purchases. You can also create your own to-do cards for reminders that aren’t already shown. In the AI BAS view, you'll see how much of your BAS is already complete and a reminder of when your BAS lodgement is due.

Use the pills across the top to filter to banking, sales or purchases tasks, like transactions you need to allocate or overdue invoices to chase up.
Create your own to-do cards for tasks or reminders that aren’t already shown on the dashboard. Just click Add to-do, enter the details and an optional due date, then click Save. Your new card is added to your dashboard.
In an AI BAS card, click Review in AI BAS. AI BAS opens in dark mode.
You can work between your current BAS period and a BAS period that’s due. Use the tabs to move between your current BAS, BAS reports ready to lodge and past BAS reports.
At the top of the BAS summary, you’ll see your GST collected, GST claimable and net BAS position.
To review every transaction included in the BAS period, click View all transactions. You can filter the list, open a transaction to review its details and make changes without losing your place.
The summary also shows the tasks that need your attention, including missing documents, GST review, uncategorised transactions and manual updates.

Click Review for each section in the checklist and review the flagged items. Any changes you accept or make, like changes to tax codes, will be saved in the associated transactions for you. AI BAS will also let you know about any transactions you'll need to manually update, such as those that haven't been matched or categorised.
Address the issues that need your attention
When you open AI BAS from a card, you'll see a checklist of things that need a closer look. These can include things like missing tax invoices, transactions where the tax code may need changing, uncategorised transactions, and manual updates AI BAS can't make for you. You can work through each area at your own pace and accept, reject or edit suggestions as you go.
Review transactions in the side panel
When you open a transaction from Missing documents, GST review or All transactions, it opens in a side panel.
The side panel shows:
the transaction narration, date and amount
the GST code, when available
the AI explanation
the action you need to take, such as accepting or rejecting a suggestion, or choosing Personal or Business
a feedback bar below the explanation
For grouped transactions, the side panel shows the underlying transactions. Select Ungroup if you need to review them separately.
Review GST claims with missing documents
The ATO requires a tax invoice for purchases over $82.50 if you want to claim GST. AI BAS finds purchases over this amount that include GST but don’t have a tax invoice attached.
Open a transaction to review it in the side panel. Choose whether to claim GST, not claim GST or edit the transaction.
If you’re claiming GST, upload or attach the supporting document during BAS preparation. The document is automatically attached to the relevant transaction in your books.

Check transactions that need the GST code reviewed
AI BAS has suggested GST codes that are new or different to your original transactions. Review and confirm the right tax code for each.
In the side panel, review the explanation and click Accept to accept the AI suggestion and AI BAS will update that tax code in the associated transaction. Click Reject to keep the original tax code, or click Edit to make your own changes.

Categorise transactions that need a category
AI BAS finds BAS-relevant transactions that need a category and suggests one for you.
Review the suggestion, then confirm it or choose a different category. You can update transactions individually or in bulk. When you approve a category, AI BAS updates the transaction in your books automatically.

Make any manual updates
At the end of your AI BAS review, you may see Manual updates required. This lists records that AI BAS couldn’t update automatically.
Export the list and update the records in your MYOB file or ask your advisor to update them. After you save your BAS report, you can continue working through the outstanding manual updates from the past BAS report. The list updates as you complete each change.

Check your BAS readiness as you go
The BAS readiness percentage updates as you accept suggestions and complete checklist items. Check in regularly through the period, and again before you lodge, to see what AI BAS has done and make sure you're comfortable with it.
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.
Review the BAS report
If you’re in a lodgement period, you can view a BAS summary:

If you want to:
Double-check the transactions included in your BAS summary, click View all transactions.
Transactions are grouped into Income and Expenses, then grouped by GST code. Each GST code group shows the number of transactions and the total amount.
Click a tax code to expand the group and review its transactions. Select it again to collapse the group. If there are more transactions, click Show more to load them.
At the top of the page, you can see your total income, total expenses and GST position.
Open the BAS report, click View report. You can then export or print the report to use when lodging your BAS via your usual method.
If it all looks good, click Save report.

This saves the report so it can appear in Past BAS reports.
Lodge your BAS to the ATO
When your BAS summary looks right, open the BAS report to review your totals and outstanding items. You can export or print the report for your records or to share with your advisor.
AI BAS prepares an ATO-ready result, but it doesn’t lodge your BAS with the ATO. You or your advisor must enter the figures into your usual ATO or agent channel and lodge the BAS there.
You can lodge your BAS:
via MyGov
through your accountant or BAS agent
by post.
For more information about these lodgement options, visit this ATO website.
In the Lodgement BAS period view, you can click Go to myGov to open myGov.
Cancelling AI BAS
You can cancel your AI BAS subscription at any time in My Account. If you cancel during your annual commitment period, you'll retain access until the end of that period, with monthly billing continuing until then.
To cancel AI BAS
You need to be the Primary Contact or Billing Contact on the MYOB account to be able to cancel AI BAS.
Log in to My Account and go to Manage my product.
Click Manage my subscription.
On the Manage subscription page > Premium features > AI BAS, click Request cancellation.
The Manage subscription page is updated to show you have cancelled AI BAS.
Frequently asked questions
Who is AI BAS for?
AI BAS is currently available to eligible non-employing businesses using MYOB Business Lite or Pro with active bank feeds. It supports GST-registered businesses using simple, cash-based BAS scenarios, including G1, 1A and 1B.
How will my accountant or bookkeeper work in with AI BAS?
Your accountant or bookkeeper can use their regular access to your MYOB file to review AI BAS suggestions, make adjustments and help you lodge your BAS. You can also share the downloadable BAS report with your advisor.
As a business owner, you can also export a CSV of all BAS‑related transactions and a BAS summary for your advisor to review before you lodge with the ATO. They can review any allocations in your file and re‑run the AI BAS checks if needed.
Does AI BAS lodge my BAS with the ATO?
AI BAS currently does not lodge directly to the ATO. It helps you 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.
How am I billed for AI BAS?
AI BAS is sold as a 12‑month subscription, annual commitment and is billed monthly in advance on the same invoice as your MYOB Business subscription, on your normal billing date.
If you subscribe mid-month, a pro-rata charge for the partial month appears on your next invoice alongside your first full month.
How accurate is AI BAS, and who is responsible for my BAS?
AI BAS uses your MYOB data and AI models 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.
However, like any AI system, it can generate incorrect information, so you must always review the results and seek professional advice where appropriate.
MYOB is not a registered tax agent, and you remain responsible for accuracy and compliance when lodging your BAS with the ATO.
Why does AI BAS look black?
To signify that AI BAS is a new, easier way to keep on top of your BAS, we’ve given it a new look and feel. AI BAS is set to ‘dark mode’, so the background will be darker with light text. When you go outside of AI BAS workflow, you’ll see the typical, lighter MYOB colours.
What if I’ve already lodged my BAS?
If you’ve already lodged and you accept a suggestion from AI BAS and change any transactions, this might mean there's a mismatch with your records and what you lodged with the ATO. You should work with your advisor to either adjust the next BAS or lodge an amendment for the submitted BAS.
