California, CA CPA Services Built Around State-Specific Decisions
California CPA work for tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals, and clients planning a California exit starts with the state tax posture, not just a city-name swap.
For tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals, the next layer is filing execution. We tie those mechanics to entity records, owner documents, payroll, sales tax, lender requests, and federal planning before a return, notice, or audit deadline narrows the options.
Local industry, ownership, funder, and residency facts shape the engagement scope. For attestation or other state-sensitive work involving California Nonprofit Audits (Nonprofit Integrity Act), California 401(k) & Employee Benefit Plan Audits, California Single Audits (Uniform Guidance) for tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals, we confirm CPA mobility, firm registration, and engagement-scope requirements before accepting the work.

California Planning Triggers We Review First
Before we quote a scope, we identify the documents, deadlines, and decisions most likely to shape the work. For California, that usually means tying local industry, owner, funder, and entity facts back to clients such as tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals.

We connect California's current tax posture to entity structure, owner compensation, residency, and multistate sourcing, then document the support for the recommended position.

California Nonprofit Audits (Nonprofit Integrity Act)
Under California Government Code §12586(e) — the Nonprofit Integrity Act — charities registered with the California Attorney General's Registry of Charitable Trusts are required to obtain audited financial statements when gross revenue equals or exceeds $2,000,000 (excluding government grants). The audit accompanies the annual RRF-1 filing. Audited statements are also routinely expected by the California Endowment, the California Wellness Foundation, the Conrad N. Hilton Foundation, and major institutional grantmakers across the state.
California 401(k) & Employee Benefit Plan Audits
California plan sponsors filing Form 5500 generally require an ERISA-compliant audit when the plan has 100 or more participants with account balances at the start of the plan year — the participant-counting rule effective post-SECURE 2.0. We perform full-scope and §103(a)(3)(C) limited-scope benefit plan audits for 401(k), 403(b), and defined-benefit plans across California, including plans sponsored by Bay Area technology companies, Los Angeles entertainment firms, San Diego biotech, and statewide healthcare systems.

We plan major-program testing, SEFA support, and grant-compliance documentation around the programs that actually drive the reporting risk.
California Lender, Bonding & Investor Audits
California lender, bonding, and investor reporting is shaped by the companies, funders, and ownership groups active in tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals. We align the assurance level, support schedules, and delivery timeline with the actual credit, surety, diligence, or capital request.
California Reviews & Compilations
For tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals, review or compilation work is often the right fit when a bank, acquirer, board, grantor, or owner needs CPA-prepared financial statements but a full audit is not required. We define the level of assurance before work starts so the deliverable fits the actual request.
California (CA) Tax & Business Landscape
Key California Tax Numbers. Personal income tax: graduated, with a top marginal rate of 12.3%, plus an additional 1% Mental Health Services Tax on taxable income above $1,000,000 — for an effective top rate of 13.3%, the highest state income tax in the United States. Corporate income tax: 8.84% (regular C-corps); 1.5% on S-corp net income (in addition to federal flow-through). Minimum franchise or annual tax: $800 per year generally applies to LLCs, LPs, LLPs, and corporations after the corporation's first taxable year. General partnerships do not owe the $800 annual tax, and newly incorporated or qualified corporations receive a first-taxable-year minimum-tax exemption. Sales and use tax: 7.25% state minimum, with local add-ons commonly bringing the total to 8.5%–10.75%. Estate tax: California has no state estate tax. Pass-through entity (PTE) elective tax: 9.3% under AB 150, available since tax year 2021 with corresponding owner-level credit on Form 540 — a critical SALT-cap workaround. For tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals, and clients planning a California exit, these numbers matter most when entity structure, owner compensation, residency, property, or investment decisions change the federal and state result.
Filing Mechanics. Individuals file Form 540 (residents) or 540NR (nonresidents and part-year residents). C-corporations file Form 100; S-corps file Form 100S. LLCs file Form 568 (with the $800 LLC tax plus any LLC fee on California-source income). Partnerships file Form 565. The PTE election is made on Form 3804 with payments via Form 3893. Returns are administered by the California Franchise Tax Board (FTB). We use those mechanics to build a filing calendar and document request list for tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals, and clients planning a California exit before deadlines compress the planning options.
Residency & Exit Planning. California uses a multi-factor residency analysis (the "Bragg factors") plus a domicile test. The FTB conducts aggressive residency audits — particularly around major liquidity events. Income from CA sources (wages earned in CA, real estate, S-corp/LLC interests, deferred compensation, certain intangibles tied to CA business) generally remains taxable to nonresidents. We routinely advise on California exit planning — pre-departure RSU/options strategy, sale-of-business timing, and trust structuring.
California Economy & Who We Serve. California is the world's fifth-largest economy, anchored by technology and venture capital (Silicon Valley/Bay Area), entertainment and media (Hollywood/LA), biotechnology and life sciences (San Diego, San Francisco), aerospace and defense (LA, Mojave, Edwards AFB), agriculture (Central Valley), and a massive real estate sector. Our typical CA clients include tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals, and clients planning a California exit.

Before accepting California work for tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals, and clients planning a California exit, we confirm the engagement type, CPA mobility, firm registration, and any attest or state-sensitive requirements.

California CPA — Frequently Asked Questions
Do I need a California-licensed CPA, or can an out-of-state CPA handle my CA tax and audit work?
CPA mobility often allows an out-of-state CPA in active good standing to serve California clients, but the right answer depends on the engagement type. For tech founders and executives with equity compensation, VC professionals, crypto investors and active traders, real estate syndicators, healthcare professionals, we confirm whether the work is tax, advisory, attest, employee-benefit-plan, or state-sensitive before accepting the engagement.
What is California's income tax rate, and when is the CA return due?
California has a graduated personal income tax with a top marginal rate of 12.3%, plus an additional 1% Mental Health Services Tax on taxable income above $1,000,000, for an effective top rate of 13.3% — the highest state income tax in the United States. Form 540 (residents) or 540NR (nonresidents and part-year residents) is due April 15, with a six-month automatic extension.
Does my California LLC really owe the $800 franchise tax even if it had no income?
Generally, yes for a California LLC: the $800 annual tax applies even when the LLC has no income, and higher-income LLCs can also owe a graduated fee. General partnerships do not owe the $800 annual tax, and newly incorporated or newly qualified corporations are exempt from the minimum franchise tax for their first taxable year, although tax on net income can still apply.
Does California have a SALT-cap workaround for partnerships and S-corps?
Yes. AB 150 created an elective Pass-Through Entity Tax (PTE) effective for tax year 2021. Eligible S-corps and partnerships pay 9.3% at the entity level on qualified net income, and owners receive a corresponding credit on Form 540. The election is made on Form 3804 with payments via Form 3893.
I'm trying to move out of California. What do I need to know about residency?
California uses a multi-factor residency analysis (the "Bragg factors") and the Franchise Tax Board conducts aggressive residency audits, particularly around major liquidity events. Key issues: timing the move ahead of any sale/exit, establishing genuine non-CA domicile (driver's license, voter registration, days in new state), and understanding that CA-source income (wages, real estate, S-corp/LLC interests, deferred compensation) typically remains taxable to nonresidents. We provide pre-departure California residency planning.
When does my California nonprofit need an audit?
Under California's Nonprofit Integrity Act (Government Code §12586(e)), charities registered with the California Attorney General are required to obtain audited financial statements when gross revenue equals or exceeds $2,000,000 (excluding government grants). The audit accompanies the RRF-1 annual filing. Federal Single Audit requirements under 2 CFR Part 200 apply separately when federal award expenditures are $1,000,000 or more.
Do you serve California clients outside Los Angeles, San Francisco, and San Diego?
Yes. Our practice is virtual-first, so we serve clients in every California county and community — including San Jose, Sacramento, Oakland, Long Beach, Fresno, Bakersfield, Anaheim, the Inland Empire, Orange County, the Central Coast, and Northern California — with the same level of access and service.
