About R&A CPAs

In 1942, when University of Arizona graduate Aaron Paul founded the accounting firm that would become R&A CPAs, Arizona had been a state for just 30 years and Tucson's population was about 35,000. Eight decades later, R&A CPAs is one of the largest accounting firms in the Southwest and one of the longest-standing businesses in Tucson.

A lot has changed over the years, but our mission−to positively impact our clients' business and personal futures by providing comprehensive, insightful, long term, and highest quality financial and advisory services that can be trusted−has never changed. Our comprehensive advisory services, depth of experience, and focus on the future have enabled us to be named a Top 500 Firm nationwide by INSIDE Public Accounting for three consecutive years, and to be recognized as a 'Best of Accounting' and 'Best of Tax' award-winner in 2021,  2022, and 2023 by Forbes Magazine. ClearlyRated has named us 'Best of Accounting' in 2021, 2022, and 2023 based on client ratings--one of just 48 firms across the US to achieve that distinction.

Domestic and international clients turn to R&A as a trusted partner that provides a strategic approach to tax, audit, and a comprehensive array of accounting services. From complex trusts, accounting, assurance, and advisory services, we are committed to serving our clients with excellence. We are proud that many of our clients have been with us over decades and generations.

R&A retains a highly-qualified, responsive team focused on our clients’ success. We provide a collaborative, supportive environment for professional development with a balance of technical expertise and practical experience. Many of our team members have been with the firm for decades, taking the knowledge and expertise from prior generations and passing the baton to some of the best and brightest in the profession!
