Stay Ahead of 2025: Your Essential Global Mobility Tax Book
Global mobility teams are entering one of the most complex tax years in recent memory. Between shifting state conformity rules, evolving federal provisions, new reporting obligations, and growing scrutiny on payroll accuracy, year-end preparation can quickly become overwhelming — especially for organizations managing employees across borders.
That’s why we created the Ineo Global Mobility Tax Book — a practical, expert-built resource designed to help HR, Payroll, and Global Mobility leaders navigate 2025 with confidence.
This comprehensive guide breaks down what’s changed, what’s ahead, and what your team must do now to stay compliant, avoid surprises, and support employees through every stage of the move.
Why This Book Matters Now
Tax rules rarely stand still, but 2025 brings a unique convergence of changes impacting mobility programs:
- Continued state-by-state divergence in TCJA conformity
- Increased emphasis on accurate gross-ups, imputed income, and exception handling
- More frequent year-end reconciliations
- Heightened focus on payroll mapping as remote work intersects with mobility
- Expanded reporting needs across payroll, HRIS, and mobility platforms
For teams balancing complex assignments, tight deadlines, and multiple jurisdictions, the risk of oversight grows quickly. This guide brings clarity to that complexity — outlining exactly what needs attention and when.
What’s Inside the Tax Book
Built by Ineo’s mobility tax experts, the guide covers the essentials, including:
- Federal & State Alignment: What’s changing, what’s permanent, and how to plan for 2026
- Payroll & Shadow Payroll: Key year-end actions, reconciliation steps, and common compliance gaps
- Allowance & Policy Updates: COLA, housing, per diems, tax protection, net-to-net
- Systems & Automation: HRIS, payroll, and tax engine updates to make before year-end
- Risk & Disaster Relief: Section 139 requirements and business-oriented security rules
- Training & Audit Preparation: Checklists, templates, and internal guidance

It’s built to be practical — the kind of resource your team can actually use as you work through the final months of the year.
