Global Tax Network

What Global Tax Network does

Global Tax Network (GTN) is a US-based professional services firm founded in 2000 that provides global mobility tax compliance, consulting, and related services to corporate clients with internationally mobile workforces. The company serves HR and mobility leaders at enterprises managing expatriates, foreign nationals, business travelers, remote workers, and permanent transfers across multiple jurisdictions, with operational coverage spanning the Americas, EMEA, and APAC. Its core service portfolio centers on Mobility Tax Compliance & Consulting (home and host country tax return preparation, hypothetical tax calculations, tax equalization support, permanent transfer tax, and notice/audit support), supplemented by Mobile Equity Services, Workforce & Risk Management, Payroll & Reporting (including shadow payroll oversight and gross-up calculations), and Program & Employee Support.

Underlying delivery is anchored by My GTN Portal, a proprietary technology platform that provides real-time visibility into employee assignments, compliance status, deliverables, timelines, and program costs, with self-service document collection, communication, and travel logging for mobile employees. GTN holds SOC 2 Type 2, EU-U.S./UK/Swiss-U.S. Data Privacy Framework, and GDPR-aligned privacy and security certifications, and partners with VeraSafe on data security. The firm generates revenue through professional services fees on a per-assignment, service bundle, or retainer basis, with quote-based engagement models tailored to client mobility program size and complexity. GTN's go-to-market is direct enterprise field sales targeting corporate mobility program managers and HR leaders, supported by content marketing, webinars, gated eBooks, and industry events. The company is privately held and founder-influenced, with David Kolb as Founder and Chairman and Bryan Williams appointed CEO in April 2026.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• SIRVA Worldwide Relocation & Moving: Global relocation and mobility services provider with tax coordination offerings. Adjacent competitor to GTN for clients seeking combined relocation and tax support, though SIRVA's primary focus is relocation management rather than tax specialization.
• Cartus: A major global relocation management company that has expanded into tax and immigration services. Competes with GTN at the intersection of mobility program management and tax compliance, particularly for enterprise clients seeking an integrated vendor.

Broad incumbents

• BDO Global Mobility Services: BDO's dedicated global mobility tax practice serves mid-market and enterprise clients with expatriate tax, shadow payroll, and policy consulting. Overlaps directly with GTN's core mobility tax compliance and consulting offering while offering a broader professional services platform.
• Deloitte Global Employer Services: Deloitte's Global Employer Services practice provides international tax, immigration, and mobility advisory. Overlaps with GTN's mobility tax compliance and consulting portfolio, with a more diversified service portfolio and larger scale.
• Vialto Partners: Spun out of PwC's Global Mobility Tax practice in 2022, Vialto is one of the largest dedicated global mobility tax and immigration advisory firms. Direct competitor to GTN for mid-market and enterprise mobility tax engagements, with significantly larger international footprint and Big Four heritage.
• PwC People & Organisation (Mobility): PwC's mobility practice provides global mobility tax, immigration, and program consulting to multinational clients. Direct competitor to GTN across the full mobility tax stack, with substantially larger resources and brand recognition.
• EY People Advisory Services (Global Mobility): EY's Global Mobility practice within People Advisory Services competes with GTN on expatriate tax compliance, tax equalization, and mobility program consulting for enterprise clients, with deeper technology and broader geographic reach.
• Mercer (Mobility Practice): Mercer's Global Mobility practice provides mobility program design, benchmarking, tax, and relocation consulting. Overlaps with GTN on the consulting and program design dimensions, while also offering relocation management GTN does not provide.
• KPMG Global Mobility Services: KPMG's Global Mobility Services practice delivers international tax, immigration, and mobility program consulting to multinational clients. Direct overlap with GTN's enterprise mobility tax services, with substantially larger global delivery infrastructure.

Direct peers

• Topia (formerly MOVE Guides): Global mobility platform combining technology with relocation, tax, and immigration services. Acquired Polaris Global Mobility (co-founded by GTN's new CEO Bryan Williams) in 2018. Competes with GTN on both the technology-enabled mobility tax delivery and the broader mobility program management layer.
