Our US tax planning and US tax compliance is done by our teams in 5 great cities – Singapore, Dubai, Lisbon in Portugal, London in the UK and Miami in Florida. These firms carry the HTJ or Advanced American Tax brand names.

To allow us to provide a wider range of services to our clients, we have Strategic Alliances with I.R.S. Enrolled Agents, International Tax Attorneys, and Qualified Accountants / CPAs.  What’s the difference?

 In short, a certified public accountant (CPA) is an expert in accounting. Tax matters are one of many specialties of CPAs.  While an Enrolled Agent (EA) is a tax practitioner who is authorized by the United States Federal government. EAs are specifically skilled tax experts who are empowered to represent clients before the IRS and can handle matters concerning collections, appeals and audits. 

A tax attorney, as the name implies, is a tax law specialist and can represent a client in a court of law.   If you find yourself in a difficult tax situation, and you feel you might be headed to court, the person to hire is a tax attorney.  

Enrolled agents can represent you before the IRS, but only an attorney can represent you in court.  Enrolled Agents are the only tax professionals who get their license to practice directly from the IRS and the United States Treasury.

There are two paths to becoming an EA. 

1. After working for the IRS for five years, an agent can become an EA without passing an examination. 
2. Without working for the IRS, one must pass a thorough background check and a three part exam. 

Enrolled agents specialize in the US tax code and tax matters. An EA must know all of the ins and outs of income tax, gift tax, inheritance tax, estate tax, and payroll tax. The continuing professional education required for an EA is seventy-two hours every three years.  

A CPA’s continuing education will cover a wide range of accounting and tax matters, but an EA’s education will focus solely on taxation.

An EA tends to have more expertise in tax matters than a CPA. EAs are the only federally authorized tax professionals licensed to practice across all 50 states. The IRS itself recognizes EAs as tax experts.
