What We Do
Tax, Audit, and CFO Services in Irvine
Most clients come to the Irvine office for one of three reasons: a tax position that needs planning, a financial statement that needs an audit, or books that need a real finance team. As a full-service Irvine CPA firm, GreenGrowth CPAs delivers all three, with a dedicated practice lead for each line.
Tax Planning and Compliance
Federal, state, and local tax for businesses and their owners. The team models positions before year end, when timing still moves the number. Coverage includes multi-state filings, IRC 280E strategy, and Section 174A research expensing.
Explore tax planningAudit and Assurance
Financial statement audits, employee benefit plan audits, single audits, and SOC reports. The audit team works under PCAOB registration and both AICPA audit quality centers. If a review would satisfy your lender, we say so before you pay for an audit.

Monthly close, reporting, forecasting, and CFO leadership without a full-time hire. The accounting team builds the infrastructure first, then runs it, so your numbers hold up in diligence, an audit, or a board meeting.

Working with GreenGrowth CPAs
What industries does GreenGrowth CPAs specialize in?
Core industries include cannabis, technology, real estate, life sciences, nonprofits, professional services, school districts, and high net worth individuals. Each industry has a dedicated practice lead.
Can GreenGrowth CPAs handle both our bookkeeping and our audit?
Under SEC and PCAOB standards, no, because those rules prohibit auditing statements the firm helped produce. In a private company audit driven by a lender, investor, or board, the AICPA framework often permits both, provided management takes responsibility for the records and safeguards are documented. We establish which combination your situation permits at the outset.
