Australian Local File
Group documentation cannot replace the Australian filing
We now turn to the Australian Local File and the limitations that frequently arise when existing group documentation is applied to the Australian filing.
Many multinational groups already prepare a Master File or transfer pricing reports for key jurisdictions. These materials provide an important foundation, but they will not ordinarily satisfy the Australian Local File requirements without further work.
The Australian Local File is not a conventional narrative report. It is a structured tax filing containing business descriptions, transaction-level data and agreement information that must be consistent with the Australian income tax return and other disclosures.

Purpose: group documentation and the Australian filing serve different needs
Australia's Country-by-Country Reporting (CbC Reporting) framework generally involves the CbC Report, Master File and Australian Local File. Australian resident entities and Australian permanent establishments of groups with annual global income of A$1 billion or more generally need to assess whether they are a CbC Reporting Entity and determine the applicable filing obligations. The filings are generally due within 12 months after the end of the reporting period, subject to entity-specific circumstances and available exemptions.
The Australian Local File comprises:
• the Short Form, which covers the Australian business, management reporting lines, restructures and intangible arrangements;
• Part A, which reports categories, counterparties and amounts of cross-border related-party dealings; and
• Part B, which provides information about material agreements and supporting documents.
Group documentation explains the broader business and policy framework. The Australian Local File focuses on what the local entity does, with whom it transacts, the amounts recorded, the contractual terms and the resulting Australian tax treatment.
Filing priority: reconcile transaction data to Australian tax records
Consider a management service fee. The group documentation may identify the transaction, while the agreement and general ledger each record an amount. During the Australian filing process, the finance team may find that part of the fee is posted to another account, a year-end adjustment remains unprocessed, head office uses a different foreign exchange convention, and the income tax return contains a further adjustment.
Each amount may have a source, but the figures may not reconcile when reviewed together. The Australian Local File, International Dealings Schedule (IDS) and income tax return may then disclose different amounts, increasing the likelihood of further ATO scrutiny.
Other recurring issues include:
• group documentation describes the Australian entity as implementing head-office decisions, while local management determines pricing, customers or inventory;
• agreements have not been updated and no longer reflect the actual settlement process;
• acquisitions, restructures or financing changes are identified by the tax team only during the filing process; and
• prior-year descriptions are rolled forward despite changes in personnel or the operating model.
What has changed: structured filing makes information easier to compare
For relevant reporting periods commencing on or after 1 January 2024, Australian Local File filings made from 2025 use a more structured format. Information previously provided in attachments is increasingly captured through standardised fields, making year-on-year and cross-filing comparisons more accessible to the ATO.
The change is broader than an increase in data fields. Information may be required from management, contract owners, human resources and group treasury, in addition to finance and tax. A late start can leave insufficient time for cross-functional verification.
Practical approach: run three workstreams in parallel
The first workstream is Australian data: the general ledger, tax adjustments, income tax return and IDS. The second is group information: policies, operating model, reporting lines and changes during the year. The third is contractual and supporting documentation: related-party agreements, financing documents and other relevant records.
When preparing an Australian Local File, we generally assign owners and deadlines across these workstreams before reconciling each transaction category. This supports the filing and identifies gaps between group documentation, Australian business practice and reported tax outcomes.
Where the ATO's administrative solution is available, lodging Part A by the income tax return due date may also remove the need to duplicate certain information in the IDS. This benefit depends on the transaction data having been reconciled early.
Group documentation is an important starting point, but the quality of the Australian filing ultimately depends on whether it accurately reflects local operations, agreements and financial data.
If your group would like to assess whether its Master File or overseas local documentation can support the Australian filing, please contact the Wis Australia tax team. A focused Australian gap assessment can provide an efficient starting point.
