Preparation Course

IQEX is borne from reciprocity agreements with Chartered Accountant Institutes/ other institutes in several Commonwealth and other countries to provide a fast-track program leading to the US CPA through a special International Qualifying Examination, abbreviated as IQEX. 

This course presents the material in a manner you will understand fully following your initial run through. The key to success is to grasp the important concepts rather than memorize rules. Complete all of the suggested multiple-choice questions and practice simulations at least twice. The more questions you review the higher your grade.


I am happy with the outcome and the content of the course, especially how “brief” it is in providing the necessary knowledge point without overloading candidates with information.

Kelly Wang CPA

Excellent course. Notes and suggestions regarding how much study time to allocate per topic were invaluable. Complex areas were explained clearly.

Sue Sekar, CA

The course did a great job focusing on the important areas. Without its help, I never would have scored 95%!

Daniel Paquin, CA

The Chartered Accountants Worldwide Network USA Comprehensive IQEX Program provided a concise and efficient process for my exam preparation. The multiple-choice questions and task-based simulations reinforced the information contained in the text material. The course was designed to focus on what is really important to learn and helped me avoid over-studying.
I completed the entire program in under 3 weeks. I was able to review the practice questions several times. My grade was 89%
Many, many thanks!

Avi Weiss CPA (Ontario, Canada)

While there are many courses available to prepare for the CPA, there are very limited options for IQEX. The CPA-NOW course was an excellent choice. The study materials focused on the key requirements and the notes were compiled in a manner that made the information easy to understand and retain. This made the CPA-NOW course both an effective and efficient way to prepare and successfully pass IQEX.

Iris Chan, CA

After a first read through the materials, then reading through them again while starting to answer the sample questions, I came to appreciate the method behind Henry’s approach. YOU REALLY DON’T HAVE TO KNOW EVERYTHING IN THE TOPICAL AREAS COVERED BY THE IQEX! Henry’s notes focus on what you need to know – that’s it. I can’t even imagine how many hours his materials saved me, but as a sole practitioner I can sure appreciate it.

Jeff Meyers, CA

The CPA-NOW IQEX training materials were an efficient way to learn what is needed to pass the IQEX. The guidance provided great direction on where I should focus my time, which was key due to my incredibly busy schedule. Without these materials I would have certainly been lost.

To which state should I apply after I pass IQEX?

After passing IQEX and joining a State Board, do I obtain all rights as a CPA?

Although you may refer to yourself as a U.S. CPA, in most jurisdictions a license to sign audit reports is not granted automatically. Such license is also not granted by simply passing the full Uniform Exam in the U.S. Various states impose additional education and/or experience requirements for those CPAs seeking permission to sign audit reports. The NASBA website lists all the individual State Boards along with contact information.

After passing IQEX, will I be able to prepare U.S. tax returns?

If you want to prepare U.S. tax returns, it is recommended that you enroll in the online tax course that is offered at There are two components, the first covering personal tax and the second dealing with corporations and partnerships. Both components offer many hours of verifiable Continuing Professional Education.
Passing the IQEX Exam and becoming a U.S. CPA automatically fulfills the recently implemented IRS tax preparer requirements. U.S. CPAs in Canada may obtain a Preparer Tax Identification Number (PTIN) and are exempt from the ongoing testing and continuing education requirements. A U.S. Social Security Number is not required. 

What is your repeat policy if a participant fails the IQEX Exam?

Candidates initially have a year’s access to the IQEX material, however if more time is required they can request this. We will also give access to latest updates and course material if required at an admin cost of $25.  Contact [email protected] to request an extension of your access. We want you to be successful and understand you may need more time to study.



NASBA (National Association of State Boards of Accountancy) has established Mutual Recognition Agreements (MRAs) with the following countries that enable you to qualify for the IQEX:
CPA Australia
Chartered Accountants Australia and New Zealand (CAANZ)
CPA Canada (CPAC)
Hong Kong Institute of Certified Public Accountants (HKICPA)
Chartered Accountants Ireland (CAI)
Instituto Mexicano de Contadores Publicos (IMCP)
Institute of Chartered Accountants of Scotland (ICAS)
South African Institute of Chartered Accountants
> CPA Ireland
Please note that, if you ultimately are considering joining a particular state board, do NOT look at that state’s education or practical experience requirements.  When you pass IQEX, you are automatically assumed to have met any state board requirements and you will not be asked to substantiate either your prior education or experience.

IQEX CPA Eligibility Criteria


Hello, my name is Henry Zimmer and I have been preparing people for the USPCA-NOW course for the past 20 years.

By way of background, I was born in New York City but moved to Montreal, Canada at the age of 12.  I received a degree with honors in English from McGill University and then lost my way, entering the Canadian CA program, receiving  my designation in 1967. While it may seem an incongruous combination, the communication skills that I learned early on have served me well over the last 50 plus years.  I became a tax specialist, wrote 15 books on taxation and investment; some texts and several for the general public that became national bestsellers.

I want to wish you success in your endeavors to obtain a US CPA and I hope you will enjoy the benefits of continuing professional and personal achievements in the future. Thank you and good luck.
