Jax C. Wheatley -



Nineteen years ago, Jax opened Rainbow Tax & Accounting to serve the needs of the LGBTQ community and beyond! Jax received their bachelor’s in accounting from Portland State University. Jax has lived in the Portland area for over 40 years, and has been working here in accounting field since 1975. Jax is active in the local community, as a member of the American Institute of Certified Public Accountants, the Oregon Society of Certified Public Accountants and the Portland Area Business Association.

Jax has first-hand familiarity with the oft complicated legal and financial arrangements of queer couples. Jax doesn’t just understand such complexity–Jax thrives on it. True equality is a long way off. But through the application of his accounting expertise, Jax strives to inform queer couples of the existing tax structure and the ways in which some of the tax benefits of marriage can be realized today.

In addition to serving individuals and couples, Jax has extensive experience with small businesses and non-profit organizations. Jax is proud to count Pride NW, organizers of Portland’s Pride Festival, as one of Rainbow Tax & Accounting’s clients. Due to his extensive experience with business and organizational development, many small businesses and non-profits in the Portland area rely on Jax’s expert counsel.

Mary Billings -


Staff Accountant

Mary came to work with us here at Rainbow Tax & Accounting in January 2016 while still working on her bachelor’s degree in accounting at Portland State University. She graduated from PSU in June of 2018 and is continuing to work toward her CPA license while working full time here at The Rainbow!

Mary found her love of accounting after moving to the Pacific Northwest 8 years ago. She realized that many members of her community needed a trustworthy financial and tax professional to guide them as they became new entrepreneurs and their lives and jobs grew. Mary has been a great fit to our comfortable and unconventional office setting. She is our Punk Rock Unicorn!

Mary provides bookkeeping, tax preparation, and QuickBooks assistance to our clients. Mary’s skills continue to grow with each passing year. Jax continues to provide mentorship and advice when necessary – including the occasional push beyond her comfort zone. 

Mary currently lives in North Portland with her partner of 12 years and their family of fur babies. She loves to cook vegan food, listen to music, hike, and craft.
