Small Business Health Tax Credit Act - Amends the Internal Revenue Code to allow small business employers (employers with between two and 50 employees) an income tax credit of between 30 to 50 percent (depending upon the number of employees) of the amount paid for employee health insurance, subject to a dollar limitation for each employee. Allows the employer to apply such credit against its minimum tax liability. Directs the Internal Revenue Service, in conjunction with the Small Business Administration, to educate small business personnel about this tax credit.
