We are an independent member of Baker Tilly International and a member of the Center for Public Company Audit Firms and the Employee Benefit Plan Audit Quality Center of the American Institute of Certified Public Accountants.

 About Us

accounting nj ny

In addition to traditional accounting, tax, and audit consulting services, Amper, Politziner & Mattia is your most trusted business advisor concerning all of your financial services needs. We have been representing organizations in both the public and private sectors since 1965 and have grown to become one of the largest independent CPA firms in the region.

Amper was founded on the premise that the entrepreneurial businessperson is looking for service from his or her accounting firm that goes beyond simply processing and presenting numbers. We recognize that Amper's growth has been due, to a large extent, to the success and growth of the clients we serve. One of the ways we work to ensure the growth and success of our clients is through our business consulting approach to client service. While our clients desire timely and cost-effective accounting, tax and consulting services, it is equally important that they retain committed professionals that take a personal interest in the success of their total organization and are capable of "Seeing Beyond the Numbers."

At Amper, we are large enough to have the resources and personnel to resolve the most complicated tax or sophisticated auditing/accounting issue, but small enough to give you the personal attention, responsive service, and senior management involvement that all our clients deserve.

Mandatory CPE Program
Amper instituted a mandatory Continuing Professional Education Program within the firm before it became a requirement of AICPA membership and all of our accountants are required to take at least 40 hours of professional education courses per year.
Successfully Completed 9 Peer Reviews
Amper was among the first firms in the area to voluntarily undergo a "peer review," and strongly supported the AICPA's vote in favor of mandatory peer reviews. In a peer review, we invite another accounting firm to extensively review our system of quality control. We have successfully completed nine peer reviews, all of which have resulted in an unqualified report, the highest possible rating. In fact, a number of CPA firms across the country have selected Amper to perform their peer reviews.
