Nicholaus McCarthy, CPA

CPA License #: 145069

Navigating the complex financial landscape requires more than just compliance—it demands proactive, tailored strategies that evolve with your business. Over the years, my team and I have worked tirelessly to refine our service offerings into a suite of curated options designed to empower business owners to not only manage but also strategically grow their businesses.

A Trusted Financial Partner

Every financial decision—whether personal or business-related—comes with unique challenges and opportunities. My mission is to simplify those choices, providing clear, actionable insights so you can feel confident you're making the right decision for you.

With deep expertise in both business and individual tax planning, combined with a holistic approach that spans full-service bookkeeping to C-suite advisory, I strive to be more than just a CPA. My goal is to be your trusted financial advisor—someone who truly understands your business from the ground up and can translate that broad experience into tangible, positive outcomes tailored to your specific situation.

A Foundation of Service

While attending the University of Nevada, Reno, where I earned duel degrees in Accountancy and Economics, I began my journey as a student volunteer with the Volunteer Income Tax Assistance (VITA) program, which provides free tax services to community members. This early experience ignited my passion for helping individuals manage their finances, as I witnessed firsthand the transformative impact these services can have on families. After college, I further honed my skills at Mowat Mackie & Anderson LLP, a mid-sized, full-service public accountancy firm in the East San Francisco Bay Area, gaining valuable experience in tax, tax planning, and attestation services for both high-net-worth individuals and small to medium-sized businesses.

Evolving Services for Today’s Business Needs

Taxes and compliance are essential and must be handled with professional care—but they should only be the starting point. I realized that staying in a traditional public accounting firm, where the focus is primarily on tax preparation and compliance-driven, retrospective financial statement preparation and attestation services, would limit my ability to deliver what I consider to be most valuable to business owners. More importantly, it would keep me from what I’m truly passionate about: proactive, personalized advisory that drives meaningful impact.

With this in mind, I founded UpCFO, P.C. Over the past five years, my team and I have developed comprehensive, modular solutions designed to support every aspect of a business’s financial health. Working closely with hundreds of small and medium-sized businesses, I’ve regularly met with owners for monthly cash flow forecasting to track performance against expectations, CEO strategic check-ins to align financial planning with business goals, accounting system improvements implemented alongside in-house teams, representing clients under audits with the IRS, State, and Local Tax Agencies, year-end tax planning sessions for both businesses and their shareholders, and more.

Through these experiences, I’ve seen firsthand what the ups and downs of business mean—not just for the company, but for the owners and their families. I have developed a deep understanding of small business owners, their challenges, and the tools they need to succeed. My mission is to empower them with financial clarity and strategic insight to help their businesses thrive.
