## What’s Changed in Penalties and Interest Regimes
Legislation passed in the **Multinational Tax Integrity Package** includes:
- **Stricter penalties** for taxpayers who mischaracterise or undervalue payments like interest or dividends that should have attracted withholding tax. ([ato.gov.au](https://www.ato.gov.au/about-ato/new-legislation/in-detail/businesses/strengthen-penalty-and-shortfall-interest-charge-provisions?utm_source=openai))
- Extending the shortfall interest charge to cover assessments on overclaimed tax offsets. This change is now law and applies to assessments from 1 April 2025. ([ato.gov.au](https://www.ato.gov.au/about-ato/new-legislation/in-detail/businesses/strengthen-penalty-and-shortfall-interest-charge-provisions?utm_source=openai))
- Penalties applicable even when taxpayers are in a net loss position, aiming to prevent avoidance through loss-making structures. ([ato.gov.au](https://www.ato.gov.au/about-ato/new-legislation/in-detail/businesses/strengthen-penalty-and-shortfall-interest-charge-provisions?utm_source=openai))
## Withholding Tax Obligations Under the Spotlight
- The ATO’s royalty withholding tax rules are tightening. Failure to properly withhold on payments to non-residents (like royalties, dividends) may now lead to penalties those obligations are enforced more strictly.

- Under the Foreign Resident Capital Gains Withholding (FRCGW) regime, rate has increased to 15% and the threshold removed from 1 January 2025. Clearance certificates have become essential to avoid withholding.

## Best Practices for Ensuring Compliance
- **Document thoroughly:** have arm’s-length agreements for payments subject to withholding, especially intercompany transactions. Maintain pricing, valuations, and support for how amounts were arrived at.
- **Timely lodgment and accuracy:** errors in filings may now lead to exposure even if company is loss-making. Meeting deadlines and accuracy in identifying withholding obligations is more critical.
- **Use clearance certificates:** where FRCGW applies, ensure you have the house in order before signing property contracts. Unexpected withholding may be applied.
- **Monitor law effective dates:** many measures, such as interest non-deductibility and new penalties, start from 1 July 2025. Plan adjustments ahead of that date.
## Example: Royalty Payment Scenario
Suppose an Australian subsidiary pays royalties to its foreign parent company for use of trademarks. Under the new changes, if the royalty rate or value is not at fair market or incorrectly characterised, the subsidiary may now be liable to:
- Withholding tax that was omitted.
- Penalties for underwithholding or mischaracterisation.
- Disallowance of deductions if the payment is reclassified.
- Loss of interest deduction if ATO interest applies post 1 July 2025.
By conducting transfer pricing benchmarking, getting legal advice, and documenting purposes and contracts, companies can protect themselves.
## Action Plan for Compliance Officers
1. Review your existing royalty, interest, and dividend payment arrangements involving non-residents.
2. Check tax filings from 1 April 2025 to ensure no overclaimed offsets; adjust where necessary.
3. Confirm clearance certificates for property transactions under FRCGW.
4. Train finance teams on updated withholding and interest interest regimes.
5. Set remediation plans for exposures before enforcement becomes strict.
