Recover Overpaid Withholding Tax

Cross-border payments are often subject to unnecessary withholding tax due to treaty misapplication, outdated processes, or missing documentation. BTGI helps identify, recover, and reduce this tax leakage, ensuring compliance and maximising efficiency.

We Review, Recover, and Reduce Withholding Tax Exposure

Whether you're making or receiving international payments, our team reviews historical transactions, applies the right treaty rates, and helps reclaim overpaid withholding tax. We also help establish future processes that minimise tax exposure going forward.

Treaty Application and Rate Review

We assess your cross-border payments to ensure you’re applying the correct withholding tax rates under relevant Double Tax Agreements (DTAs).

Missed Exemptions and Refund Opportunities

We identify payments that may qualify for exemptions or reduced rates under international treaties, and help lodge refund claims for overpayments.

Payment Flow Analysis for Foreign Suppliers

We review outbound payments like royalties, interest, and dividends to detect tax leakage and uncover recoverable amounts.

Compliance with Documentation and Reporting Standards

Incorrect or missing paperwork is a common cause of denied treaty benefits. We make sure all required records are complete and audit-ready.
Our withholding tax recovery approach is fast, non-invasive, and backed by deep expertise in international tax law and cross-border withholding regimes.

Why Businesses Choose BTGI?

Chief Financial Officer
BTG recently performed a thorough indirect tax review of the Group’s past 4 years of supplier payments. This involved a vast quantity of work, which the BTG team completed in good time and to a high quality. BTG’s expertise in this area meant their feedback was well-informed and their process improvements will benefit the Group. Overall, the service provided by BTG represented fantastic value for money and I would recommend them to any organisation who wants to understand how much unclaimed GST they can recover.

Frequently Asked Questions — Withholding Tax Recovery and Review Services

Withholding tax is a tax deducted at source from cross-border payments such as interest, dividends and royalties. The rate depends on local laws and applicable tax treaties between countries.

Overpayments are common when treaty rates aren’t applied, documentation is missing, or payments are misclassified. It often goes unnoticed until a full review is done.

Yes. If you’ve overpaid, you may be eligible for a refund depending on local tax laws and treaty entitlements. BTGI helps you assess, document, and submit refund claims where available.

Most jurisdictions require a valid Certificate of Residence from the foreign payee, along with DTA forms or declarations. We help ensure your records are audit-ready and accepted by tax authorities.

Absolutely. Our review not only identifies past overpayments but also helps you structure future payments correctly to avoid unnecessary tax leakage. If your business also deals with imported goods, our customs duty reviews can uncover missed concessions or overpaid duty charges.

No, we also help inbound recipients of Australian-sourced income ensure they’re not overtaxed and are claiming reduced rates or exemptions where eligible. For businesses with cross-border sales or expenses, our global VAT recovery service can also unlock significant refunds and compliance benefits.

There’s no upfront fee. You only pay if we succeed at withholding tax recovery or deliver cost savings through the review process.

Yes. All reviews are conducted using current legislation, tax treaties, and documentation standards, ensuring full compliance with the ATO and overseas tax authorities. Our compliance-led approach also extends to GST recovery and other Australian indirect taxes, helping clients stay audit-ready and optimise returns.
