Janathan L. Allen

An Integrated Approach

Janathan Allen is an experienced tax attorney and business lawyer who integrates business, legal, tax and accounting strategies to provide her clients with better answers to their questions and more informed strategies to leverage their opportunities.

Most businesses have separate tax attorneys, business attorneys, CPAs and accountants, tax preparers and financial advisors. If you take the same problem to each professional, they will provide what they genuinely believe is the right and best answer. However, it will only be based upon their unique (and somewhat limited) perspective.

The business attorney will have no idea how the solution they are recommending impacts business operations or your accounting systems. The financial planner has no idea how their recommendation may be impacted by interstate or international tax implications.

This is the genuine value of the integrated approach Janathan Allen and Allen Barron take when they work with you as a client on any challenge or opportunity.


A Montana native, Janathan Allen brings domestic and international tax, accounting, finance knowledge to Allen Barron, Inc. and legal experience to Janathan L Allen, APC. Allen has worked with a diverse group of businesses, advising clients in legal, financial and tax arenas.

Beginning her career in the public accounting arena, she moved into the private sector as tax director for a biotech firm, Hybritech, Inc. She progressed to controller and CFO/Legal Counsel positions for a number of San Diego companies before becoming a partner in Allen Barron, Inc. and founding Janathan L. Allen, APC.

Why Do I Practice as an Attorney and an Accountant?

I enjoy helping business professionals and individuals with assets to solve complex problems and develop strategies which help to accomplish their goals. Clients often underestimate how hard I will work and how far I will go to solve their problems. There are only so many hours in a day, and I work to select clients with an opportunity I can help them to realize or a problem I can help them to solve.

In this fast paced and global economy it is not sufficient to answer most business questions from a single perspective of tax, legal, accounting or the impact on the operations of the business itself. Issues are integrated.

The problem is, most genuine business questions and challenges are actually a symptom of a deeper issue. A business attorney really doesn’t fully know or understand the implications of many decisions upon your company’s tax exposure. You may need to change your strategies surrounding entity structure, organization and tax strategies, but the accounting system must be able to capture crucial data to inform business and tax decisions.

If all you need is a quick opinion from a single tax, legal, accounting or business perspective Janathan L. Allen and Allen Barron can quickly and cost-effectively deliver it.

However, in many cases what appears to be a simple fire or challenge within your company actually encompasses many of the above disciplines. In these cases, a business attorney may provide a recommendation based upon their unique perspective. Yet their recommendation is not in the company’s best interest from a tax, accounting or operational business perspective.

Janathan Allen and Allen Barron integrate these disciplines to approach your business challenges from a higher and broader perspective. We understand how the pieces of the overall strategy fit together, and how one seemingly isolated decision or challenge may affect a much broader segment of the overall picture. We provide a complete perspective saving you the time and expense of attempting to work with 5 separate professionals without ever really getting to the solution which reflects all aspects of the challenge at hand.
