CPA Insurance in San Francisco

Start with services actually delivered, people who may rely on the work, and the firm's policy history. Professional liability is central, while cyber, crime, employment, general liability, and other questions depend on records, controls, premises, workforce, contracts, and authority. A declaration page alone cannot show that covered-professional-services wording matches the work. This guide is for cpa and accounting firms reviewing operations in San Francisco, California.

Which operations does this review address?

California-based CPA and accounting firms, including public accounting, client advisory, tax, bookkeeping, and combined practices. Sole practitioners, partnerships, professional corporations, and multi-office firms can use this scope. An accounting label does not establish that a policy includes every service; attest, tax, bookkeeping, payroll, valuation, forensic, and advisory work should be described separately.

Coverage questions—not a universal policy package

Coverage to review	Why discuss it	Limits and questions
Professional liability or accountants E&O	Review tax, compilations, reviews, bookkeeping, CAS, valuation, forensic, and other services separately, including who relies on each deliverable and whether prior acts are preserved.	Ask whether wording addresses services, subcontractors, predecessor work, duties, and reporting obligations. A certificate or engagement letter is not a coverage determination.
Cyber and privacy	The firm may hold tax returns, payroll, bank, identity data, and credentials across cloud, portals, email, and local systems.	Identify data, vendors, authentication, backups, response, notifications, and security warranties. Ask about vendor events and social engineering.
Crime, funds transfer, and social engineering	Payment instructions, payroll access, accounts, and authority to initiate or approve transactions differ from an accounting error.	Document system access, vendor changes, wires, and payroll release. Compare policy, endorsements, controls, and exclusions without promising a response.
General liability and business property	Client visits, premises, leased equipment, paper records, and ordinary operations create questions separate from professional advice.	Check locations, leases, property, tenant requirements, and remote work. Compare package contents and exclusions rather than assuming them.
Workers compensation and employment exposures	Employees, seasonal staff, remote workers, partners, and contractors can have different status and duties.	Describe workforce, payroll, entities, and insured people accurately; do not use a low payroll or contractor label to cheapen a quote.

What drives the quote and what to bring

The useful comparison is your actual operations and complete policy terms. Do not add overlapping policies into a supposed required package or treat a national small-business price as a local total insurance budget.

Service mix and revenue across tax, attest, bookkeeping, CAS, valuation, forensic, and advisory work.
Client size, industry, concentration, third-party report reliance, contracts, limits, indemnities, and requested excess.
Claims, complaints, regulatory inquiries, known circumstances, prior-acts terms, entity history, and continuity.
Revenue, payroll, seasonal staffing, locations, remote work, subcontractors, acquisitions, and retiring partners.
Client-record sensitivity, cloud vendors, payment authority, access controls, and incident response.

Practical coverage review in San Francisco

Professional firms working in San Francisco should identify the service, client deliverable, project address, contract indemnity, and any site or construction-administration role. The City's permit guide distinguishes local department review, while the contractor/vendor handout shows that a public contract can require evidence of insurance before work is ordered. That is useful contract context, not a statement that every professional service needs the same policy. Discuss claims-made continuity, prior acts, professional liability, cyber, general liability, and auto only against the firm's actual services and client requirements.

List each service, deliverable, project or client location, contract limit, indemnity promise, and any design, inspection, or construction-administration responsibility.
Preserve claims-made retroactive dates, prior-acts terms, known-circumstance disclosures, and reporting arrangements when comparing renewals.
Request the complete City or client insurance clause before agreeing to additional-insured, primary/noncontributory, waiver, or notice language.
Describe client data, cloud systems, subcontractors, employees, and field travel separately so cyber, professional, general-liability, and auto terms are not confused.

San Francisco — Building permits for business

San Francisco's business-permit guide describes six local project steps: confirm what is allowed, complete the forms and fees, submit for review, obtain approval, and complete inspection. It identifies separate local sign-offs, including the Department of Building Inspection (DBI), Fire Department, and, for food work, Public Health; DBI checks construction against approved plans, permits, and local and state codes.

San Francisco — Hazards and Climate Resilience Plan

The City's 2025 Hazards and Climate Resilience Plan profiles 13 natural hazards and organizes mitigation actions around buildings, communities, and infrastructure. The City says the plan is updated every five years, so a property or continuity review should use the current plan rather than assume that every San Francisco address has the same exposure.

City and County of San Francisco — Insurance Requirements

San Francisco's contractor/vendor insurance handout says a successful bidder must submit the required certificate of insurance and additional-insured endorsements before receiving an order or contract agreement. The handout directs bidders to review the insurance portion of the particular bid document for the required coverages.

Application and renewal preparation checklist

Professional liability is often claims-made. Preserve the policy sequence, retroactive or prior-acts information, notice history, entity history, predecessor work, acquisitions, retirement, and extended-reporting terms before changing a broker, carrier, ownership, or service mix.

List services and approximate revenue, including tax, attest, bookkeeping, payroll, CAS, valuation, forensic, and consulting work.
Prepare de-identified engagement examples with deliverables, intended users, client industries, and third-party reliance.
Gather current and prior liability declarations, forms, endorsements, applications, retroactive dates, and known circumstances.
Map client-data systems, portals, vendors, authentication, backups, payment authority, and incident contacts.
Separate employees, partners, seasonal staff, contractors, related entities, contracts, renewal dates, and open claims.

Compare the policy first, then the membership economics

OnePark Pacific combines two separate opportunities: finding a competitive insurance option and returning a substantial share of the commission we earn.

Market-shopping savings are not guaranteed. Rebates are calculated using the actual eligible placement—not a hypothetical higher premium.

Insurance premiums can include compensation paid to the broker. OnePark Pacific makes that compensation part of the membership value: we return 70% of the eligible commission we actually earn and receive on your policies. We retain 30%, alongside your annual membership fee, to support our brokerage services.

A hypothetical renewal comparison—not a quote

For cpa and accounting firms, assess the applicable coverage and eligible commission separately for each policy. These illustrative amounts do not establish availability or cost in San Francisco.

Suppose the eligible commissionable premium is $24,000, the hypothetical policy commission is 12.5%, and the hypothetical account membership fee is $350. Eligible commission is $3,000; the 70% projected rebate is $2,100. Membership-only benefit is $1,750, and modeled annual outlay is $22,250 before other taxes or charges. These are teaching assumptions, not local premiums, typical commissions, an available policy, or a quoted membership fee.

For a smaller hypothetical account with $2,000 eligible at 5% and a $199 fee, the rebate is $70 and membership-only benefit is −$129. The membership would cost more than its rebate. Two hypothetical policies of $12,000 at 10% and $8,000 at 15% produce a $1,680 rebate; subtract one $400 account fee, not two, for $1,280 benefit.

How the account calculation works

Use one row per policy. Annual premium (P) and its eligible commissionable portion (E) are different inputs: E must be between zero and P. Enter the actual or explicitly hypothetical commission rate for each row, and one annual membership fee for the account. The starting example is $50,000, not an average cost or eligibility statement.

Eligible commission = SUM(E × commission rate). Projected rebate = eligible commission × 70%. Membership-only benefit = rebate − one annual membership fee. Annual outlay = SUM(P) + separately stated taxes and other fees + membership fee − rebate. Ineligible premiums, taxes and unrelated policy/payment fees do not generate commission in this model.

Dollar inputs are handled in cents. Each policy commission and the account rebate are rounded half-up to cents. Unknown fee, eligibility or commission inputs leave the estimate incomplete. Negative benefits remain negative. A quoted input is still subject to policy and written membership terms; the calculation does not verify it.

Compare a baseline only when coverage and terms are genuinely comparable. Baseline annual outlay includes premiums, applicable fees and existing rebates. A later commission rebate does not reduce the insurer's premium or the cash due when a policy starts.

Membership terms and important limits

Rebates are a percentage of eligible commissions—not premiums. Membership fees vary by FTEs and gross revenue. Policy eligibility and actual savings require review.

Your annual membership price is based on your company’s full-time-equivalent employee count and gross annual revenue. Share those details and we will confirm your price, review eligible policies, and help you compare the projected rebate with your membership cost.

Insurance premiums are separate. OnePark retains 30% of eligible commissions in addition to the membership fee. Final pricing and eligibility are confirmed before enrollment.

Carrier approval and commission rights vary. No retroactive rebate on commissions paid to another broker is promised. Joining does not automatically transfer, bind, cancel, or change a policy. Renewal prices and coverage may change.

Membership is exclusively for businesses primarily based in California. Operations in other states are allowed and reviewed individually, but they do not make a non-California-based business eligible.

Independent comparison means the markets OnePark can access, not every insurer or a guaranteed lowest price. Membership is not a blanket group insurance policy. The annual fee can exceed the rebate. An inquiry does not enroll you, bind insurance, or change coverage. Rebates follow the written membership terms and depend on qualifying commissions actually earned and received; a later rebate is not an insurer premium reduction or immediate cash saving.

Frequently asked questions

Does a CPA policy automatically cover bookkeeping, tax, and fractional CFO work?

No. Disclose each service and compare it with covered-professional-services wording, endorsements, exclusions, and the application. Tax, bookkeeping, CAS, and CFO work can create different duties.

Why do engagement letters matter during an accounting insurance review?

They show the agreed service, deliverables, client responsibilities, timetable, and intended users. They do not rewrite a policy or guarantee a defense, so compare the letter with the actual form.

Is a client payment mistake the same as a professional-liability claim?

Not necessarily. Funds handling, deception, employee dishonesty, cyber events, and accounting errors may implicate different agreements and exclusions. Describe authority and controls without assuming a response.

What should a growing accounting firm do after acquiring another practice?

Map predecessor entities, services, policy periods, prior acts, known circumstances, contracts, and post-closing work. Obtain policy-specific review before assuming the buyer's policy covers earlier engagements.

Does a San Francisco project or property make my business eligible?

No. The business must be primarily based in California. Owning a California property or taking a California project does not by itself meet that requirement. Operations in other states require review; an inquiry is not approval or insurance binding.

Which parts of my insurance payment generate a rebate?

Only qualifying commissions that OnePark actually earns and receives count under the membership terms. Taxes, unrelated fees, ineligible premiums and another broker's past commissions are not a rebate base. Confirm each policy rather than assuming every coverage qualifies.
