National American Payroll Association

The American Payroll Association is the nation’s leader in payroll education, publications, and training. Since 1983, it’s been our goal to increase the payroll professional’s skill level through knowledge and a supportive community of peers. Today, we offer top-rated payroll conferences and seminars, a complete library of resource texts, and industry-recognized certifications.

Our success is achieved through membership. We value APA membership as a shared commitment to improving the work lives of payroll professionals. We empower our members not only through education, but by seeking recognition for the work they do in today’s business and legislative environment. Representing more than 20,000 members, we are the industry’s highly respected and collective voice in Washington, D.C. and beyond.
