About Online Taxman
International US tax specialists for expats and entrepreneurs
For 15+ years, we've focused exclusively on international US tax. Nothing else. This depth of specialization means we understand not just the tax code, but the reality of living and doing business across borders.
Our team is globally distributed across the Americas, Asia, and Europe. We've lived the expat experience, so we know the challenges you face go beyond just filing forms.
Our focus isn't just getting your returns filed. It's making sure you're positioned strategically for your cross-border life.
“I'm American and live in Portugal. These guys have been extremely professional and detailed orientated. They've corrected mistakes I've made and advised on my fairly complex case. Overall very happy!”
Deep expertise, personal approach
What started as a specialized expat tax practice has evolved into a comprehensive international tax partner.
Today, we handle the full scope of international tax needs: compliance, business structuring, pension classification, financial advisory, and strategic planning for complex cross-border situations. Our team has built deep expertise across these areas while maintaining the personalized approach of a boutique firm.
Many of us have lived internationally, so we bring both technical precision and genuine understanding to every engagement.
