Fractional CFO Services in San Diego
Fractional CFO and controller services for San Diego construction, contractors, distribution, manufacturing, and service businesses.
California Coverage
Fractional CFO and Controller services for San Diego-area businesses.
Vessel Advisors supports businesses across San Diego County and the broader Southern California market — life sciences and biotech, defense and aerospace, contract manufacturers, hospitality operators, professional service firms. Our team includes CFOs and Controllers local to San Diego, backed by a vetted national bench of senior finance leaders who support businesses that need expert help.
San Diego is a distinctive business market. Life sciences and defense anchor the base, but the mix of contract manufacturing, hospitality, and cross-border trade produces a set of finance-function pressures that generalist CFOs rarely see all in one place.

The Market
San Diego runs on two economies at once — a research-intensive one anchored by biotech and defense, and an operational one that supplies and supports it.
San Diego runs on two engines that don't look much alike. The first is technical and R&D-intensive: biotech, medical device, defense contractors, and the venture-backed companies clustered around them. The second is operational: contract manufacturers serving those primary industries, hospitality and tourism operators, professional service firms, and the trades that build for all of it.
What we see most from a finance standpoint: R&D-heavy companies burning capital toward a milestone that don't have the runway modeling and investor reporting an institutional round expects; contract manufacturers with real GAAP compliance requirements but bookkeeping-level infrastructure; hospitality operators managing multi-property portfolios without consolidated visibility; and family-owned businesses in the second or third generation whose accounting hasn't kept pace with the company.
What we see most:
- Life science and medical device companies preparing for institutional rounds, partnership deals, or acquisition.
- Defense contractors and aerospace suppliers managing DCAA-compliant accounting and government contract complexity.
- Contract manufacturers serving primes across biotech, defense, and consumer goods.
- Hospitality and tourism operators with multi-property portfolios and seasonality to manage.
- Family businesses and founder-led operators preparing for the next stage they hadn't planned for.
Industries
Where we work most in Southern California.
Life sciences and medical device
Biotech, med device, diagnostics, and therapeutics companies at the pre-revenue and early-commercial stages. Runway modeling, milestone-based reporting, cap-table hygiene, and the reporting sophistication investors expect. More on how we serve technology and growth-stage companies.
Defense, aerospace, and government contracting
Prime and subcontract defense manufacturers, aerospace suppliers, and government contractors. DCAA compliance, indirect rate management, contract profitability, and the accounting discipline government audits require.
Manufacturing and industrial
Contract manufacturers, industrial suppliers, and consumer product operators serving Southern California and cross-border markets. Inventory accuracy, gross margin visibility, and standard cost discipline. Our manufacturing case study shows the pattern.
Hospitality, tourism, and real estate
Multi-property hospitality operators, restaurant groups, and real estate developers across the region. Consolidated multi-entity reporting, property-level P&L, and cash flow forecasting through seasonality. More on how we serve real estate operators.
San Diego Taxes and Compliance
California still lets San Diego companies deduct research costs as they spend them.
Life sciences and defense companies also work under the state's research credit rules and a $5 million yearly cap on business credits. The city sets its own minimum wage, which rises again on January 1.
Taxes
Sales tax
7.75% in the City of San Diego
The 7.25% state base carries one district tax, 0.50% for the San Diego County Regional Transportation Commission. CDTFA lists no City of San Diego district tax, and the city's November 2026 ballot carries only council seats.
Business tax certificate
$34 a year at 12 or fewer employees
Above 12 employees, the city charges $125 plus $5 per employee, and the $4 state fee applies at every size. A late payment costs $25 or 10%, plus 1% a month.
Research costs
Deductible as spent, or over five years
California never adopted the federal capitalization rule for research and experimental costs that took effect in 2022. Domestic and foreign research costs can be deducted currently, or amortized over five years by election.
Research credit
15% of qualified research above the base
The credit covers research done in California, and corporations add 24% of basic research payments. From 2025 a company can elect the simplified credit instead: 3% of qualified expenses above half the three-year average, or 1.3% if any of the prior three years had none.
Credit cap
$5,000,000 of credits a year through 2029
Business credits can reduce tax by at most $5,000,000 a year from 2024 through 2029, and from 2030 by the greater of 70% of tax or $5,000,000. Credit the cap blocks can be elected as a refund, paid at 20% a year over five years starting in the third year.
Employers
Minimum wage
$17.75 an hour in San Diego
The rate applies to anyone who works at least two hours in a week inside city limits. The 2027 rate, $18.35 from January 1, is already posted.
Hospitality minimum wage
$19.00 at hotels, $21.06 at amusement parks and event centers
The city's hospitality wage took effect July 1, 2026 for covered employers. It steps up each July, reaching $25.00 for both groups in 2030, then follows inflation.
Earned sick leave
City rules now match the state's
San Diego's ordinance accrues one hour per 30 worked, caps accrual at 80 hours and allows a 40-hour annual use limit or a 40-hour front-load. Coverage starts at two hours of work in a week in the city.
Enforcement fee
$1.47 per employee, billed with the tax certificate
Since July 1, 2025 the city has billed a minimum wage enforcement fee for each employee working in San Diego. A proposal would rename it and raise it to $2.82 from November 1, 2026, pending City Council approval.
Non-competes
Void for employees, wherever signed
California voids employee non-competes no matter where or when they were signed, and it gives employees a right to sue over them for damages and fees. Employers had to tell current employees, and former employees employed after January 1, 2022, by February 14, 2024 that such clauses are void.
Questions San Diego owners ask
Does a pre-revenue biotech get any value from the California research credit?
The credit is nonrefundable, so a company with no tax carries it forward, with no expiration, until it has tax to offset. Within a combined reporting group, it can be assigned to another member. More on how we serve technology and growth-stage companies.
Why don't our federal and California research deductions match?
California didn't adopt the 2025 federal change in §174A, so a federal catch-up deduction for 2022 through 2024 research costs needs a California adjustment. Because California never required capitalization, those costs were deductible for California when incurred.
Does a new San Diego startup owe California's $800 minimum tax?
A newly formed corporation owes no minimum franchise tax in its first taxable year, but any income is still taxed at 8.84%. From the second year, the $800 minimum applies with or without a profit. LLCs don't get the first-year exemption; for 2027 through 2029, their first-year tax is $400.
Can California losses offset income in 2026?
Not for larger taxpayers. Net operating loss deductions are suspended for tax years 2024 through 2026 for corporations with California taxable income of $1 million or more, and for individuals with net business income or modified AGI at that level. Suspended losses get one to three extra carryforward years, and the suspension ends after 2026 under current law.
Can a San Diego company make employees repay training costs if they leave?
Not under contracts signed from January 1, 2027. California bans terms that make a worker pay a debt, fee or penalty when employment ends, including training repayment, with exceptions for tuition toward a transferable credential and qualifying retention bonuses. A violation costs the greater of actual damages or $5,000 per worker, plus fees. The ban was first set for 2026 and delayed a year in September 2026.
Is a founder's stock community property in California?
Yes, if the shares were acquired during the marriage while the couple lived in California. Either spouse can manage community personal property, and because the community estate answers for debts either spouse takes on during the marriage, one spouse's personal guaranty can reach community assets, those shares included. See how we work with fast-growing companies.
