Expert VAT support for Isle of Man businesses
The Isle of Man operates within a Customs Union with the United Kingdom, meaning its VAT rules are closely aligned with those of the UK. VAT in the Isle of Man is reported and paid to Isle of Man Customs and Excise rather than HMRC, and the island has not implemented the UK’s ‘Making Tax Digital’ requirements. Additionally, there are some variations in VAT rates and practices that businesses need to consider.
Navigating the complexities of indirect taxes can be daunting, but indirect tax specialists understand the challenges you face. That’s why we provide clear, practical advice tailored to help you and your business. From VAT compliance and recoverability calculations to resolving disputes and optimising VAT recovery in financial services, our comprehensive services ensure your business stays compliant. We can streamline your indirect tax processes so you can focus on growth and success.
VAT is a crucial consideration for many businesses, and efficient management is essential to ensure compliance, optimize cash flow, and avoid penalties. Without proper planning, VAT can become a direct cost to your business. At Grant Thornton, we help you understand your obligations, assess VAT risks, and develop strategies for effective VAT recovery.
Our VAT advisory team offers a full suite of services, from registration and compliance to strategic planning. With extensive experience across key Isle of Man sectors—including property, aviation, and e-gaming—we are well-equipped to support your business with expert, tailored advice.
