A garnishee debit needs the right accounting treatment, not a guessed expense code

The bank feed gives you an amount, not the accounting answer
An ATO garnishee debit appears in the bank feed and the bookkeeper assigns a general expense code to clear the reconciliation. Before relying on the resulting profit report or tax balance, ask the accountant to review the entry. The transaction needs to be connected to the underlying records, and its proper treatment should not be guessed from the bank description alone.
Locate the amount and supporting notice
Imagine a company seeing a substantial debit while its ledger already contains tax liabilities for earlier periods. Keep the notice, bank transaction and available tax account records together. Identify the actual taxpayer and amount. Do not assume the debit is a new cost of the current job simply because it appeared in this month's bank activity.
Use a supported transaction record
business.gov.au recommends keeping records of business expenses, bank transactions and tax information. Provide those records to the accountant so the posting can be assessed. Record unresolved allocation questions explicitly. The general recordkeeping guidance does not prescribe the journal entry for your situation; the accountant must consider the actual liability and transaction history.

Check both profit and liability reports
Ask whether the initial posting has incorrectly changed reported operating costs, left a liability unreconciled or reduced an amount twice. Preserve the original entry and the explanation of any authorised correction. In the company example, management could draw the wrong conclusion about job profitability if a payment relating to an earlier tax obligation is treated as an unexplained current operating expense.
Keep cash movement separate from classification
Whatever accounting correction is required, the money has still left the account unless an actual reversal is confirmed. Do not restore it to available cash because a journal was changed. Update the cash forecast from the real transaction and seek advice about the notice and business position. Better classification does not itself recover the money or change the collection action.
Review the automated rule
If a bank-feed rule caused the error, ask the accountant how it should be corrected and checked on future transactions. Tell those using the management reports when revised figures are available. A properly supported posting helps distinguish the cash shortage from the accounting presentation, so decisions are made from an explained tax balance and reliable operating information.
