Dedicated to serving the diverse needs of the offshore maritime industry.
What We Offer
GMRS provides compliant employment solutions tailored to the needs of offshore contractors.
Whether you’re working in maritime security or operating ROVs, we support international assignments outside the UK, simplify administration, and align with applicable tax and regulatory requirements.
Employment Structure
Stay Flexible While Fully Protected
GMRS employs offshore workers through a non‑UK employer for international assignments carried out wholly outside the UK, providing compliant contracts and payroll structures aligned with maritime operations.
This structure does not apply to UK‑based roles or assignments that fall within UK PAYE.
Benefits Include:
- Offshore employment structure designed to support eligibility for Seafarers’ Earnings Deduction, subject to HMRC qualifying criteria
- UK-compliant structure to help you qualify for Seafarers’ Earnings Deduction (SED)
- Full access to a secure payroll system
- GMRS manages payroll within the offshore employment structure. Individuals remain responsible for their personal tax affairs in accordance with their country of residence.
Compliance & Tax Support
Our systems and processes are designed to support compliance for offshore employment arrangements, including where Seafarers’ Earnings Deduction may be relevant.
Many contractors mistakenly believe they qualify for SED.
If you are unsure, we can provide guidance on how HMRC’s qualifying conditions apply to your circumstances.
We also provide expert guidance and resources on IR35, helping you understand how the legislation may impact your offshore earnings and status.
For those needing further assistance, we partner with trusted accountants to offer accountancy packages tailored specifically for offshore contractors.

Support for Maritime Security Companies
We work closely with maritime security companies to simplify the resourcing and management of offshore and international assignments.
By engaging personnel through GMRS’s offshore employment structure for international assignments outside the UK, companies reduce their exposure to UK PAYE and labour supply chain risks when the engagement falls outside the UK jurisdiction.
GMRS provides an offshore employment framework aligned to maritime operations, rather than UK agency employment or UK PAYE payroll.
This approach can also reduce the need for in‑house payroll and HR administration for offshore assignments, helping streamline operations while maintaining appropriate contractual and payroll structures.
