Jeff Manahan, CPA
Founder & Principal
Jeff Manahan is a Certified Public Accountant with more than 10 years of accounting, tax, and financial leadership experience. He founded Manahan CPA to provide attentive, high-quality service to individuals and closely held businesses — with a licensed CPA directly involved in every engagement.
Jeff's background combines public accounting and tax work with hands-on financial leadership inside operating businesses. He has worked directly with owners and management teams on tax planning, financial reporting, budgeting, forecasting, cash flow, and operational decisions — giving him a practical understanding of both personal tax matters and the financial realities businesses face as they grow.
That experience shapes how Manahan CPA approaches client work. Business returns are prepared with an understanding of the underlying books and the owner's individual tax picture. Financial reports are designed to be useful — not just accurate. And advice considers cash flow, timing, and the realities of running a business, not only technical compliance.
Jeff approaches every engagement with attention to detail and a commitment to understanding the client's complete situation. The goal is not simply to complete the work, but to provide dependable support and useful guidance throughout the year.

Our Approach
How We Work
Accuracy First
Every return, every set of books, every financial analysis is reviewed carefully before it leaves our office. We don't cut corners on the work.
Useful Explanations
We explain what we're doing and why. If something affects your taxes or your finances, you'll hear about it in plain language — not accounting jargon.
Year-Round Availability
Tax questions don't only come up in April. We're available throughout the year to answer questions, review decisions, and help you plan ahead.
Long-Term Relationships
We work best with clients who want a CPA they can count on over time — someone who knows their situation and can give them informed, consistent advice.
