Built for what you're building.
Todd Nims CPA is a boutique advisory and tax firm for Arizona's owners, investors, and families. Led by a CPA with four decades of experience, we bring clarity and proactive guidance to every financial decision — so you can move forward with confidence.
Our clients don't come to us for a once-a-year transaction. They come for clarity, strategic guidance, and a financial partner genuinely invested in what they're building — for years, not tax seasons.

A licensed CPA firm held to a professional standard — confidence you build with a partner who is still here, year after year.
Responsiveness
Questions answered and deadlines met. Our systems keep your work moving, so you're never left waiting or wondering.
Proactive guidance
We bring you the move before the deadline — not the surprise after it. Planning is built into the relationship.
Financial confidence
Clear advice you can act on, so every major decision is made from a position of understanding — never guesswork.
Broad expertise for business owners — with deeper specialties where it counts.
Most of our clients are business owners across every kind of industry. Within that broad foundation, we've built dedicated depth in the areas where Arizona's opportunity — and complexity — runs highest.

Advisory, tax, and accounting — from one firm that knows your numbers.
These aren't separate vendors you have to coordinate. They're parts of a single relationship, grounded in your actual books and returns.

Deep, dedicated guidance across our areas of focus — with special depth in real estate and construction.
Because your advisor is the same firm that prepares your return, the guidance is grounded in your real numbers — never generic advice.

A boutique firm, built to endure.
Todd Nims CPA was founded by Todd Nims, who began his career in 1984 at Arthur Andersen & Co. in financial services and real estate audit and tax — a foundation few Arizona practitioners can claim. He holds a Bachelor of Science in Accounting from California Lutheran University.
As Founder and Managing CPA, Todd sets the standard for every client relationship: credentialed expertise, proactive guidance, and advisory that is always an extension of the firm's tax and accounting work — never consulting bolted on beside it.
We built the firm to last. Consistent processes, modern systems, and a relationship-first approach are designed to serve clients exceptionally today — and to scale gracefully as additional professionals join us.
"Your numbers tell a story. Our job is to help you write the next chapter."
— Todd Nims, Founder & Managing CPA
