H. ARNOLD SHERMAN. I provide international tax planning services world-wide through H. Arnold Sherman Professional Corporation, of which I am the sole shareholder.

Over forty years of experience in the international tax planning field, together with current personal knowledge of the tax systems of more than sixty countries, provides clients with unequalled international tax planning advice.

Access to an informal network of high quality tax advisers throughout the world and close working relationships with the Tax Specialist Group in Canada, and with Chown Dewhurst LLP in the United Kingdom are particularly helpful.

  • Limited French and Spanish


Clients include both public and private corporations and their shareholders, officers and employees. One speciality is international tax planning for individuals, especially clients who move to another country, including their retirement planning, where appropriate. A good deal of my personal tax planning work involves offshore jurisdictions and offshore trusts. Many of my international tax planning assignments are the result of referrals from law firms and professional accountants throughout the world.

Another speciality is advising established domestic businesses when they begin to expand internationally.

Many of my international clients have no contacts with Canada. Medium-sized and smaller accounting firms, both in Canada and elsewhere, consult me, rather than the "Big Four".


Imaginative and original international tax planning is my commitment to clients. I assess carefully the risk each client is prepared to take, resulting in a tailored approach. "Package" solutions — never!

I handle only international tax planning, and make appropriate referrals when clients require tax compliance services, or purely domestic tax advice.

My support is a very extensive international tax library, so I can keep up with tax developments and tax treaties in almost every country of the world. If I cannot handle your problem I say so, and find the best person to help you.

I travel extensively, both to visit clients and to maintain my knowledge of world-wide tax systems.

General Business Practices

Operating without professional staff means that clients are never billed for the professional services of anyone else. You will never deal with my assistant!

"Know your client" rules are scrupulously observed.

Only clients whose motives I understand and agree with are accepted.

I bill for my professional services on an hourly basis, unless otherwise agreed.
