Meet Ryan Sims

Meet Ryan Sims, CPA

Your proactive tax partner in San Diego

I’m Ryan Sims — a San Diego CPA, Enrolled Agent, and small business owner who believes tax and accounting should feel clear, calm, and handled — not stressful or confusing.

I work with individuals and business owners who want a tax professional that shows up, explains things in plain English, and helps them plan ahead — not just react at tax time.

A different kind of CPA relationship

I’m licensed as a Certified Public Accountant in California and an Enrolled Agent with the IRS, which means I’m authorized to represent clients at every level and handle everything from straightforward individual returns to complex business tax situations.

But credentials alone don’t build trust.

  • What clients value most is knowing:
  • Their questions will be answered
  • Their situation won’t be judged
  • Their taxes won’t be handled at the last minute
  • Their CPA actually understands what it’s like to run a business

That’s the relationship I aim to provide.

Experience that translates into better guidance

Before founding Proactive Accounting & Tax, my background included work as a tax advisor, auditor, bank examiner, and business professional across multiple industries — as well as service as a military veteran.

That experience shaped how I work today.

I don’t just look at forms.
I look at systems, timing, structure, and decisions — because those are the things that actually impact your tax outcome.

My role is to help you stay compliant, reduce your tax liability legally, and make informed decisions with confidence.
