Why choose Abacus Tax for your expatriate tax return?

Personalized Service

We do not just prepare tax returns: we build relationships. At Abacus Tax, you work with the same tax advisor every year. This means that the same advisor will get to know your unique needs and circumstances—and the tax matters that concern you most.

Specialized Knowledge

Expat tax returns often require computations and disclosures that are overlooked by most domestic US tax accountants. Our team is specifically trained and licensed to handle cross-border and expatriate tax returns. We know which unique forms are required for our expatriate clients —and how to prepare them.

Secure Data

We value the privacy and security of our clients’ personal information very seriously.  We encrypt all your files, always storing your files in data centers with bank-level security, and using industry leading programs and document management systems.


We are open and receptive to all forms of communication including postal mail, emails, telephone and video calls. Discussing your tax returns can be done with you in person, in teleconferences or in video conferences.
