## What’s Changing: Key Integrity Measures
Recent legislative reforms have sharpened Australia’s approach to tax integrity. Core changes include:
- **Thin capitalisation and Debt Deduction Creation Rules (DDCR)**: New rules introduced under the *Treasury Laws Amendment (Making Multinationals Pay Their Fair Share – Integrity and Transparency) Act 2024*. These control deductibility of interest and require disclosure of restructuring in response to DDCR.

- **Reporting of restructures**: New Reportable Tax Position (RTP) questions in schedules for those who restructure in response to DDCR.

- **Local File/Master File (LCMSF) Schema Version 4.0**: Updated schema for short-form/long-form local file international tax reporting takes effect for reporting periods from 1 January 2025.

- **Better transparency around withholding on foreign payments**: Dividends, interest, royalties to foreign residents now under increased scrutiny.

## Compliance Action Points by Business Type
| Business Size | Priority Actions |
|---|---|
| Large Groups / Multinationals | – Review intercompany loans, ensure they meet third party debt test. <br>– Update tax positions and filings in light of DDCR; disclose restructures accurately. <br>– Make sure LCMSF local file disclosures are up to date with schema v4.0. |
| SMEs with overseas payments | – Confirm whether BRE status is valid; some companies may unintentionally misstate eligibility. <br>– Ensure correct withholding is applied for overseas payments. <br>– Use latest tax software that includes updated RTP schedules. |
| Sole traders / Indigenous businesses | – If undertaking foreign contracts or distributing foreign income, apply foreign income offset rules. <br>– Keep thorough documentation for travel and residency. |
## Monitoring and Self-Assessment Guidance
- Use **draft rulings and guidelines**: PCG 2024/D3, draft rulings on DDCR and thin cap provide insight into how ATO examines risk. Seek early feedback.

- Record keeping is essential: intercompany agreements, repayment schedules, valuation of intangible assets. Many histories of LCMSF feedback show missing disclosures of restructures or overseas management reporting.

## Penalties & Enforcement
- Misreporting or non-disclosure of reportable restructures may lead to penalties under RTP laws. <br>
- Withholding tax non-compliance can result in interest, penalties, and audit risk. <br>
- ATO’s Tax Avoidance Taskforce, which has delivered large revenue outcomes (~AUD $5–6 billion) in recent years, will be enforcing the new integrity laws.

## Example Compliance Checklist
- Have any restructuring actions been taken since 1 July 2024 in relation to debt? If yes, document and prepare disclosure in RTP schedule. <br>
- Update your local file format to LCMSF V4.0 if using short form / master file reporting. <br>
- Review company loan arrangements/related party interest payments and ensure debt test compliance. <br>
- Confirm base rate entity eligibility each year, consider aggregated turnover (including offshore affiliates) and passive income thresholds. <br>
Staying compliant under these changing rules means being proactive — reviewing your arrangements, updating documentation, and leveraging early guidance. Take steps now to avoid costly corrections later.
