Running Balance Account
The Running Balance Account (RBA) is a statement produced by the ATO, which details taxes due and payable by, or refundable to, an Agent’s registered clients.
Amounts payable might include unpaid taxes and GIC penalties or there may be amounts the Commissioner owes the taxpayer that you have only been made aware of after viewing the RBA for your client on the Tax Agent's Portal.
In order that you may provide your client with an Estimate that will not differ markedly from the Notice of Assessment, there are two fields for a description and an amount contained in the Return Properties > Estimates > Running Balance Account, for you to enter such amounts. Where the amount is a credit, precede it with a hyphen.
The description you type and its amount will be included in the [F4] Estimate.
