A well-designed global assignment policy helps your business manage international placements with clarity, consistency and control.

We help you develop or refine your policy to address the key financial, tax and practical considerations of moving employees across borders, including:

• Policy design and review tailored to your business and assignment needs
• Tax equalisation and protection frameworks aligned with your approach
• Cost-of-living adjustments (COLA) with a clearly defined methodology
• Home and host payroll responsibilities and arrangements
• Social security and totalisation considerations to help manage compliance risks

The result? A policy that is commercially sound, tax-conscious, fair to employees and practical to administer.

Keep every international assignment organised, on track and in view with the SAIL Secondment App. Our proprietary app gives HR and Finance a central place to monitor assignments, track key dates and maintain a clear record of the advice and support provided to both employers and employees.

The app helps you manage the moving parts of international assignments, including:

• Assignment tracking to log new international placements and monitor progress

• Tax and immigration reminders to keep key dates and deadlines on your radar
• Centralised records of advice provided to employers and employees
• Cost-of-living adjustment (COLA) tracking to monitor assignment-related adjustments

• Assignment timeline dashboard for a clear overview of each placement

The result? Greater visibility, better organisation, more control over deadlines and all your key assignment information in one place.

A successful international assignment starts with the right plan. Before your employee moves, we work with you to assess the tax, financial and compliance considerations, helping you make informed decisions before the assignment begins.

During the session, we help you:

• Assess tax exposure in both home and host countries
• Identify permanent establishment risks that could affect your business
• Determine payroll arrangements across jurisdictions
• Define cost-of-living allowance (COLA) methodology for your employee
• Review benefit equalisation to establish a clear and consistent approach
• Align communication strategies so everyone understands their responsibilities and expectations

The result? A clearer understanding of the costs, risks and responsibilities involved, with an agreed structure and the documentation needed to move forward with confidence.

An international assignment comes with new responsibilities, and employees need to understand what these mean for them. We meet directly with your employees to explain their tax and compliance obligations, answer their questions and help them feel prepared for the move.

Our sessions cover:

• Host-country tax obligations so employees understand their responsibilities in their new jurisdiction

• Tax residency rules and how an international move may affect their position
• Payroll implications and what to expect when working across jurisdictions
• Reporting requirements to help employees stay on top of their obligations

• Practical Q&A sessions to address individual concerns and provide clarity

Our support doesn’t stop at the first meeting. Follow-up sessions help employees stay informed as their circumstances change, keep their obligations on track and feel confident that they have the right support throughout their assignment.
