Why California CPA Firms Are Moving to Offshore Accounting

California CPA firms are not losing staff to better accounting practices. They are losing them to the most well-funded employers in the world.

Bay Area · Tech & VC

In the Bay Area, accounting professionals in San Francisco, San Jose, the Peninsula, and the East Bay can move from a CPA firm to Google, Apple, Salesforce, or any of hundreds of venture-backed startups and see their total compensation change significantly. The tech industry does not compete for accounting staff the way other employers do. It sets a pay level that regional practices cannot match, and it recruits continuously. Firms in Palo Alto, Santa Clara, and Oakland know this every time a mid-level staff accountant leaves.

LA & San Diego

In Los Angeles, the entertainment industry sets the competition. A staff accountant with a few years of experience can move from a Century City, Beverly Hills, or Woodland Hills practice to a major studio, a streaming company, or a talent agency. The creative economy in Southern California is large enough and wealthy enough to pull accounting professionals out of CPA firms on a regular basis. In San Diego, the biotech and life sciences cluster pulls accounting staff toward Sorrento Valley, La Jolla, and Torrey Pines, where companies like Illumina and a dense network of clinical-stage biotechs recruit at a scale most San Diego practices cannot reach.

When firms do hire across any of these markets, the true cost runs well above the offer:

California employer payroll taxes, SUI, and SDI add substantially on top of base salary

Office overhead in Bay Area and Los Angeles markets is among the highest in the country

Accounting staff turnover is high in all three markets: one departure resets the recruiting timeline and the full cost

60–70%
Staffing cost reduction

California CPA firms that move to outsourced accounting with Acculink reduce staffing costs by 60 to 70 percent, without giving up quality, turnaround times, or data security. Our team of 300+ professionals, including CPAs, Enrolled Agents, Chartered Accountants, and Big-4 alumni, integrates into your existing workflow through dedicated accounting outsourcing services and operates on your schedule.

Engagement Model

Hire Dedicated Staff for Your California CPA Firm

The most common way California CPA firms work with Acculink is the dedicated staffing model: one professional, a dedicated accountant, tax preparer, bookkeeper, or payroll expert, who works exclusively for your firm, integrates into your workflow, and operates under your direct supervision. This is not a shared service or an outsourced task queue. It is your person, on your schedule, doing your firm’s work.

Each hire is matched based on your tax return volume, bookkeeping complexity, software platforms, and client industries. You meet the professional before the engagement starts. You set the tasks and review the output. Acculink handles employment, IT infrastructure, data security, and compliance.

For firms that prefer to outsource defined work without managing staff directly, Acculink’s project-based model handles delivery end-to-end. See engagement models for a full comparison of both options.

Context that carries forward

CA PTE workpapers June 15 estimated payments CA non-conformity adjustments LLC gross receipts fee S-corp franchise tax (Form 100S)

CA PTE workpapers with June 15 estimated payment tracking per electing entity, California non-conformity adjustments computed separately from federal for affected clients, LLC gross receipts fee calculations, and S-corporation franchise tax on Form 100S: in a typical California CPA firm, this complexity applies across the majority of the client roster. A dedicated professional who knows each client’s filing history, their PTE election status, and their entity structure handles that work with context that carries forward. Project outsourcing picks up cold each time.

What Your Dedicated Acculink Team Handles

From daily bookkeeping to California-specific tax workpapers, your dedicated team works across the platforms your clients already use.

Tax Preparation and Compliance

Individual returns (1040), C-corporation filings (1120), S-corporation returns (1120S), LLC/LLP/Partnership returns (1065), trust returns (1041), tax review, and tax planning. For California specifically: CA PTE workpapers (FTB Form 3804) include the entity-level tax calculation, June 15 estimated payment tracking via FTB Form 3893, and PTE credit coordination on each qualified taxpayer’s Form 540. California non-conformity adjustments are handled for every return where federal and California diverge: the §199A QBI deduction does not carry to California, federal bonus depreciation is disallowed, §163(j) interest expense applies differently, and R&E expenditures remain fully deductible in California. California LLC gross receipts fee workpapers (Form 3536 where applicable) and S-corporation franchise tax at 1.5% (Form 100S) are prepared alongside federal filings. Explore our tax preparation outsourcing.

California Industries

California Industries Your Acculink Team Covers

California CPA firms serve client bases that do not exist anywhere else in the country. The industries that dominate the Bay Area, Los Angeles, and San Diego require different accounting work than the national average, and a generic offshore team is not the same as one that has prepared equity compensation workpapers for venture-backed companies, handled loan-out S-corporation returns for entertainment clients, or tracked R&D expenses for clinical-stage biotechs. Acculink’s dedicated professionals are matched to your firm based on your clients’ specific industries.

Core CA verticals
#1
US ag state by output

Technology and Venture Capital

Bookkeeping, financial reporting, and workpaper preparation for software companies, SaaS businesses, hardware companies, and VC-backed startups. Bay Area firms serving early- and growth-stage companies deal with cap table accounting, 409A valuation support, R&D tax credit workpapers (including the California R&E credit under RTC §23609), multi-state nexus, and equity compensation tracking across ISO and NSO grants.

Entertainment and Media

Bookkeeping and workpaper preparation for production companies, studios, music publishers, talent agencies, and the loan-out corporations entertainment clients use to structure income. Los Angeles firms handle royalty and residual income, passive activity from film investments, and the interaction between loan-out S-corporation income and California’s 1.5 percent entity-level franchise tax.

Biotech and Life Sciences

Financial reporting, R&D expense documentation, grant tracking, and workpaper preparation for clinical-stage biotechs, contract research organizations (CROs), and medical device companies.

Real Estate

Property accounting, rental income tracking, depreciation schedules, 1031 exchange documentation, and investor-facing financial reporting. California’s real estate market is one of the largest and most complex in the country, with high property values, significant depreciation work, and the interaction between federal passive activity rules and California’s own depreciation treatment.

Agriculture

Farm accounting, commodity income tracking, crop insurance proceeds, Subchapter T cooperative returns, and multi-entity farm structures for Central Valley and coastal agricultural businesses. California is the largest agricultural state by output, with federal and California-specific issues that require consistent, experienced workpaper preparation.

Matched to your client base

A generic offshore team is not the same as one that has done your clients’ work before. Acculink’s dedicated professionals are matched to your firm based on your clients’ specific industries.

In-House Hiring vs. Offshore Accounting for California CPA Firms

The salary figure is only part of the story. Here is how the true cost of a California hire compares to a dedicated Acculink team.

Most CPA firm partners know the salary number for an accounting hire. Fewer have run the true cost. In California, employer-side FICA, SUI, SDI, ETT, health insurance contributions, retirement matching, paid leave, and office overhead add 30 to 40 percent on top of base pay. In Bay Area and Los Angeles markets, those overhead costs are higher than most of the country. That gap between job posting salary and actual cost per hire is where Acculink creates immediate value.

In-House Accounting Staff in California With Acculink CPA
Direct Cost Market-rate CA salary, among the highest in the US $8–$35/hr, all-inclusive
Employer Overhead Payroll taxes, SUI, SDI, ETT, benefits, and office overhead on top Included in the hourly rate
True Annual Cost Substantially more than the salary figure No hidden additions
Onboarding Timeline 4–8 weeks minimum (recruiting, interviews, training) 5–10 business days
Data Security Depends on your firm's own infrastructure SOC 2 Type II Certified
Trial Period None 40 hours free
Exit Terms Notice period, potential severance No lock-in, no penalties
CA-Specific Tax Work Separate hire needed, or work sent out CA PTE, LLC fee, CA non-conformity, and S-corp franchise tax workpapers included

California CPA firms working with Acculink report cost reductions of 60 to 70 percent on accounting staffing compared to equivalent domestic hires. For a Bay Area or Los Angeles firm carrying two or three accounting positions, the savings justify the shift within the first quarter.

CA Tax Environment

The California Tax Environment Your Acculink Team Is Built For

California does not follow federal tax law. The Franchise Tax Board administers a parallel tax system that diverges from the IRS code at multiple points, and every client with California nexus requires a separate California computation. Pass-through owners deal with an entity-level election that has its own return, its own quarterly deadline, and its own credit calculation per owner. LLCs face an annual minimum franchise tax and a graduated gross receipts fee. S-corporations pay an entity-level franchise tax with no federal equivalent.

Federal / IRS Internal Revenue Code California / FTB Franchise Tax Board SEPARATE CA CALC per client

Every client with California nexus requires a separate California computation.

California Pass-Through Entity Tax (CA PTE)

FTB Form 3804 FTB Form 3893 Form 540 credit June 15 deadline

California enacted a pass-through entity tax election available to S-corporations, partnerships, and LLCs taxed as partnerships, extended through tax year 2030 under Senate Bill 132. Eligible entities pay California income tax at the entity level. Qualified taxpayers claim the corresponding credit on their California Form 540, working around the federal SALT cap.

CA PTE adds two recurring obligations for every electing client: the entity-level return (FTB Form 3804, filed with the entity’s timely filed return) and a June 15 estimated payment of 50 percent of the prior year’s PTE tax or $1,000, whichever is greater, paid via FTB Form 3893. Under SB 132, missing the June 15 payment reduces the qualified taxpayer’s credit, so the deadline matters. Acculink handles FTB 3804 workpaper preparation, estimated payment tracking, and PTE credit coordination on each owner’s Form 540, staged for your licensed CPAs to review.

50% of prior year’s PTE tax or $1,000, whichever is greater, via FTB Form 3893.

California Non-Conformity to Federal Tax Law

California consistently decouples from key federal provisions. The non-conformity items that generate the most additional preparation work for California CPA firms:

The §199A qualified business income deduction does not apply in California. Every pass-through client that takes the QBI deduction federally requires a California addback.

Federal bonus depreciation is not allowed in California. California-specific depreciation runs parallel to federal for every client with depreciable assets.

California does not follow the §163(j) interest expense limitation rules, requiring separate California interest expense calculations for affected entities.

Research and experimental expenditures remain fully deductible in California regardless of the federal §174 capitalization and amortization rules. Clients with R&D activity need separate California R&E treatment.

California LLC Gross Receipts Fee and S-Corporation Franchise Tax

Every LLC doing business in California pays an $800 annual minimum franchise tax. LLCs with California-source gross receipts above $250,000 also pay a graduated gross receipts fee, rising in brackets to $11,790 for receipts of $5,000,000 or more. The estimated fee is due June 15 for calendar-year LLCs projecting gross receipts above the $250,000 threshold (Form 3536). For firms with a significant LLC client base, the fee calculation and estimated payment tracking are recurring workpaper items on every LLC return.

California S-corporations pay the higher of a 1.5 percent franchise tax on California net income or the $800 minimum, filed on Form 100S. Unlike most states that treat S-corporation income as purely pass-through, California imposes an entity-level franchise tax. Acculink prepares Form 100S workpapers alongside federal 1120S filings, staged for your licensed CPAs to review.

Compliance & Security

Compliance and Data Security for California CPA Firms

Sharing client financial data with any outside team, whether offshore or domestic, triggers specific legal and professional obligations. California adds requirements that go beyond what most other states impose. Below is how Acculink operates within each framework that applies to California CPA firms.

IRS Section 7216: Offshore Disclosure Consent

Under IRC §7216 and Treas. Reg. §301.7216-2, a tax return preparer must obtain the client’s written, knowing, and voluntary consent before disclosing tax return information to any service provider outside the United States. The consent must name the recipient, identify the information being shared, and state the purpose. For 1040-series taxpayers, additional specific language is required under Revenue Procedure 2013-14.

Acculink provides California CPA firms with ready-to-use §7216 consent templates as part of standard onboarding. For a California practice, this applies to every individual client whose California return is handled offshore alongside their federal 1040, which in a typical California firm is the majority of the individual client roster. Failure to obtain a valid §7216 consent before disclosing offshore is a federal misdemeanor.

California Business and Professions Code §5063.3: Engagement Letter Requirement

California imposes a disclosure obligation that applies on top of §7216 and is specific to California-licensed CPA firms. Under California Business and Professions Code §5063.3 and 16 CCR §54.1, a California CPA firm must obtain the client’s written consent before confidential client information is disclosed to any person or entity outside the United States, and that consent must be documented in the engagement letter, which must state that confidential information will be transferred outside the US.

The §7216 consent covers tax return information specifically. The BPC §5063.3 requirement covers confidential client information broadly and must be addressed in the engagement letter before offshore work begins. These are two separate obligations, and both must be satisfied. Acculink provides California CPA firms with both the §7216 consent language and the engagement letter disclosure language required under BPC §5063.3.

California Privacy Rights Act (CPRA)

California’s Privacy Rights Act, effective January 1, 2023, applies to for-profit businesses that meet any of three thresholds: annual gross revenue exceeding $25 million, processing personal information of 100,000 or more California consumers or households, or deriving 50 percent or more of annual revenue from selling or sharing personal information. Data processed pursuant to the Gramm-Leach-Bliley Act is exempt at the data level for GLBA-covered financial services purposes, which covers most client financial data a CPA firm processes.

Whether or not the CPRA applies to your firm’s full data footprint, Acculink’s infrastructure already exceeds its requirements. Our data handling has been independently audited under SOC 2 Type II and ISO 27001:2013, covering access controls, encryption, audit trails, and incident response.

California Board of Accountancy: Standards on Outsourcing

The California Board of Accountancy (a division of the California Department of Consumer Affairs) permits CPA firms to use offshore support staff, provided the licensed CPA firm retains supervisory responsibility for all work product and has obtained client consent in compliance with California Business and Professions Code §5063.3 and IRS §7216. Acculink’s engagement model is built entirely around this requirement. Your licensed CPAs review and approve every deliverable before it goes to a client. Acculink staff do not file returns, do not contact your clients, and do not represent your firm in any professional capacity.

Yes. California CPA firms may use offshore support staff under both California Board of Accountancy standards and AICPA professional conduct rules. The firm must retain supervisory responsibility for all work product, meaning a licensed CPA reviews and signs off on every deliverable before it reaches a client. For tax return work, written client consent under IRS §7216 is required before sharing return information with any offshore provider. California also requires, under Business and Professions Code §5063.3, that your engagement letter disclose the transfer of confidential information outside the United States and obtain written client consent. Acculink provides compliant templates for both requirements at onboarding.
That is your decision, with one California-specific requirement. Under California BPC §5063.3, your engagement letter must disclose that client information will be transferred outside the United States and obtain written consent before offshore work begins. Beyond that legal requirement, how you communicate your staffing model to clients is entirely up to you. Acculink operates as your back-office team: we never contact your clients, do not appear in any client-facing materials, and do not represent your firm externally.
