How about the usual Qualified :

Eligibility for Qualified Personal Service Corporations

Because there are significant tax advantages, many well paid professionals organize these unique types of C-Corporations.

The Internal Revenue Service (IRS) uses two tests to determine if a corporation is eligible to qualify as a personal service corporation:

1. More than 95 percent of the business’ activities are services provided by employee-owners in their respective industry.
2. 95 percent or more of the corporation’s stock must be held directly or indirectly through partnerships, S-Corporations, or other qualified personal service corporations, either by employees of the QPSC, former employees, estates of said individuals, or anyone who acquired stock though inheritance.

If these conditions are not met then we get nonqualified.
