Fractional CFO & Controller Services for Businesses in Seattle and the Puget Sound

Fractional CFO Services in Seattle

Fractional CFO and controller services for Seattle construction, contractors, distribution, manufacturing, and service businesses.

Puget Sound Coverage

Serving Seattle's mid-market.

Vessel Advisors supports businesses across Seattle and the Puget Sound — manufacturers and aerospace suppliers, distributors and logistics operators, construction contractors, professional services firms, and the broader mid-market that gets less attention than the region's tech giants.

The Seattle story isn't only Amazon and Microsoft. The Puget Sound has a deep industrial and business base — aerospace supply chain, maritime, distribution, construction, professional services — that's been quietly building real businesses for decades.

The Market

The Puget Sound business base gets overlooked in the tech narrative.

Seattle's tech economy gets the headlines, but the region has a long and deep industrial heritage — Boeing supply chain, maritime services, food distribution (Costco is from here), specialty manufacturing, construction, and the professional-services firms that support all of it. Companies in this band are often founder-led or family-owned, and they frequently come to the finance question once the business has scaled past what its original setup was built to handle.

What we see most:

  • Aerospace supply chain manufacturers and contract producers serving the Boeing ecosystem and broader industrial customers.
  • Distribution operators — industrial, food, consumer products — serving the Pacific Northwest and broader Western US.
  • Construction contractors and trades businesses across commercial and residential markets.
  • Professional services firms — engineering, IT services, consulting — with utilization-driven economics.
  • Maritime and logistics operators tied to the Port of Seattle and the broader Pacific trade economy.

Industries

Where we work most in Seattle.

Manufacturing and aerospace supply

Aerospace suppliers, specialty manufacturers, and contract producers across the Puget Sound industrial base. Standard cost, gross margin visibility, customer concentration, and operational reporting are the recurring conversations.

Distribution and logistics

Distributors and 3PL operators serving the Pacific Northwest and Western US. Inventory accuracy, customer-level profitability, and asset utilization are baseline.

Construction and trades

Commercial contractors, residential builders, and the trades businesses behind sustained Puget Sound growth. WIP accounting, job-level profitability, and bonding capacity baseline.

Professional and technical services

Engineering, IT services, consulting, and architecture firms with utilization-based economics. Partner compensation modeling, project profitability, and the discipline to scale beyond the founders.

Washington Taxes and Compliance

Washington taxes revenue instead of profit. Service businesses at $5 million and up now pay 2.1%.

Washington has no corporate income tax, and its B&O tax on gross receipts comes due in a losing year as well as a profitable one. Seattle, Bellevue and Tacoma add B&O taxes of their own, Seattle adds two employer taxes on pay, and several state rates rise on January 1, 2027.

Taxes

B&O tax

1.5% to 2.1% of service income, set by size

The business and occupation tax falls on gross receipts with no deduction for costs, and LLCs, partnerships and S corporations pay it the same as corporations. The service rate follows the prior year's service income, with affiliates combined: 1.5% under $1 million, 1.75% from $1 million, and 2.1% from $5 million since October 1, 2025.

B&O increases

0.5% on manufacturing, wholesale and retail from 2027

Manufacturing and wholesaling, now 0.484%, and retailing, now 0.471%, all rise to 0.5% on January 1, 2027. A company with more than $250 million a year of Washington taxable income also pays a 0.5% surcharge on the excess from 2026 through 2029, though manufacturing-related income is exempt from it.

City B&O taxes

0.658% on Seattle service revenue above $2 million

Seattle's rates, set through 2032, are 0.658% for services and 0.342% for manufacturing, wholesaling and retail, after a $2 million standard deduction; a business with less than $2 million of taxable revenue owes none. Bellevue charges 0.1596% on gross receipts and a quarterly square-footage tax on offices whose administrative or support work, such as accounting, HR and payroll, isn't tied to Bellevue receipts. Tacoma charges 0.4% on services and 0.11% on manufacturing.

Sales tax

10.55% in Seattle, 10.5% in Tacoma, 10.3% in Bellevue

Seattle and King County each added 0.1% on January 1, 2026, Tacoma's rate rose in two steps on April 1 and July 1, 2026, and Everett's rate is 9.9%. The buyer owes the tax, and tax a seller doesn't collect becomes the buyer's use tax.

Sales tax on services

IT, staffing and advertising taxed since October 2025

Since October 1, 2025, ESSB 5814 has treated these as retail sales: IT training, support and consulting, custom software and websites, temporary staffing, security and investigation, live presentations, data processing such as payroll processing, and advertising other than most traditional media. A business that buys them pays sales tax, and one that sells them collects it and pays the 0.471% retailing B&O rate instead of the service rate. Sales between members of an affiliated group are excluded.

Income tax

None through 2027, 9.9% above $1 million from 2028

Washington taxes no wages or ordinary income today. ESSB 6346 taxes individual income above a $1 million household deduction at 9.9% from January 1, 2028, and offers pass-through entities a 9.9% entity-level election. Voters decide a repeal initiative, I-645, on November 3, 2026.

Employers

Minimum wage

$21.30 in Seattle, $17.13 statewide

Neither rate allows a tip credit. Bellevue and Tacoma use the state rate, and Everett is phasing in its own: $20.77 at employers with more than 500 employees in Washington and $19.77 at those with 15 to 499 from July to December 2026. The posted 2027 rates are $22.14 in Seattle and $17.73 statewide.

Seattle payroll taxes

5% of each employee's Seattle pay above $1 million

The Social Housing Tax has applied since January 1, 2025, at every business size. JumpStart adds 0.746% to 2.557% of the pay of employees earning $194,452 or more, at businesses with $9,074,409 or more of Seattle payroll in 2025. The employer pays both, and both count owners' guaranteed payments and net distributions as pay.

Paid leave and long-term care

1.13% for PFML, 0.58% for WA Cares

The PFML premium applies to wages up to $184,500; employees pay up to 71.43% of it, and only employers with 50 or more employees owe the 28.57% employer share. WA Cares takes 0.58% of all wages with no cap, withheld from employees' pay, and its benefits began July 1, 2026. PFML covers medical leave, and Washington has no state disability insurance program.

Unemployment insurance

$78,200 wage base in 2026, $82,000 in 2027

New employers pay 115% of their industry's average rate until they have two and a half to three years of history, and construction follows its own industry's average. An established employer's experience and social-cost rates together are capped at 6%.

Paid sick leave

1 hour for every 40 worked, with no annual cap

State law covers every employer, allows up to 40 hours of carryover and lets employees use leave after 90 days. Seattle's ordinance scales with worldwide full-time equivalents; at 250 or more, employees accrue an hour for every 30 and carry over up to 72 hours, or 108 with a PTO policy. Tacoma's ordinance covers employees who work 80 or more hours a year in the city and adds bereavement as a use.

Pay transparency

Pay ranges in every job posting at 15 or more employees

Each posting, including one placed by a third party, must show the wage scale or salary range and a general description of benefits. Damages run $100 to $5,000 per violation; for postings through July 27, 2027, an employer has five business days after written notice to correct a posting before any penalty. No employer may seek an applicant's wage history.

Questions Seattle owners ask

Who collects sales tax on a Washington construction job?

The prime contractor. Construction for a customer is a retail sale, so the prime charges sales tax on the full contract price and pays retailing B&O, while its subcontractors pay wholesaling B&O; both rates rise to 0.5% on January 1, 2027. A speculative builder pays sales tax on its materials and subcontractor charges instead, and the sale of the finished real estate is exempt from B&O and sales tax. More on fractional controllers for construction companies.

How much retainage can be held on a private Washington job?

Retainage on a private project is capped at 5% of the contract price of completed work, a limit that has bound owners, contractors and subcontractors since July 23, 2023, and suppliers since 2024. A retainage bond of up to 5% must be accepted in place of cash retainage. The cap does not apply to single-family residential construction under 12 units. On the final payment, interest of 1% a month runs from 30 days after the work is completed and accepted.

What are the lien deadlines on a Washington project?

A lien claim must be recorded within 90 days after the last labor or materials were furnished, and the suit to foreclose it filed within eight months of recording. Suppliers, equipment lessors and professionals who don't contract with the owner must first send a notice of the right to claim a lien, which protects only what they furnished in the 60 days before it. Laborers and subcontractors hired directly by the prime don't need that notice, except on owner-occupied residential remodels.

If we buy a Washington company, can we inherit its unpaid taxes?

Yes, unless part of the price is held back. When a seller disposes of more than 50% of its assets, its B&O, sales and other excise taxes are due within 10 days, and the buyer must withhold enough of the price to cover them until the seller produces a Department of Revenue receipt or a certificate that no tax is due. A buyer who skips the holdback is liable for those taxes, and the same rule covers workers' compensation premiums owed to the Department of Labor and Industries. The buyer is released if the Department of Revenue issues no assessment within six months of written notice of the acquisition.

What does Washington tax when an owner sells the company?

The capital gains tax takes 7% of long-term gains up to $1 million and 9.9% above that, after a standard deduction, and its return is due with the federal return. Gains on real estate and depreciable business assets are exempt. Real estate is taxed separately: selling 50% or more of a company that owns Washington real property, counted over 36 months, is a taxable sale of the property at its true and fair value under the real estate excise tax, at state rates from 1.1% to 3.0% with local tax on top. See how we help owners prepare a business for sale.

Can we still use non-competes in Washington?

Not from June 30, 2027, when every non-compete becomes void regardless of when it was signed; employers must make reasonable efforts to notify current and former workers by October 1, 2027. Until then, one is void unless the employee earns more than $126,858.83 in 2026, or $131,326.59 from January to June 2027. Covenants made in the sale of a business survive only when the signer buys or sells 1% or more of it. Non-solicitation agreements are limited to 18 months and to customers the employee dealt with directly.

Do I need my spouse's consent to sell company assets?

It depends on who manages the business. Washington is a community property state: property acquired during a marriage or domestic partnership is community property, and either spouse may manage it alone, with exceptions. If both spouses take part in managing a business, neither may buy, sell or encumber its assets or goodwill without the other's consent; if only one does, that spouse may act alone in the ordinary course of business. Both must sign to sell or encumber community real property.

When is our Washington unclaimed property report due?

Reports and payments are due by October 31 and cover the 12 months before July 1; they are filed electronically with the Department of Revenue. Most property is presumed abandoned after three years, and wages, commissions, bonuses and payroll cards after one. Only a business holding reportable property files, and Washington has no negative report.

Figures verified October 2026 against the Revised Code of Washington and the Legislature's bill reports; the Washington Department of Revenue, including its fourth-quarter 2026 local sales tax rates; the Department of Labor and Industries; the Employment Security Department; the WA Cares Fund; the Secretary of State; and the Cities of Seattle, Bellevue and Tacoma. This is general information, not tax or legal advice.

Seattle Finance Talent

Seattle pays its financial managers 11.4% more than the national median.

The Bureau of Labor Statistics counts 8,500 financial managers in the Seattle metro, the category that covers controllers and finance directors. Median pay is $185,550 against a national median of $166,570, and the top tenth earns $324,570 or more before benefits and payroll tax. Accountants and auditors earn a median of $99,370, compared with $83,680 nationally.

King, Pierce and Snohomish counties have 5,466 business locations with 50 to 499 employees, and the metro added 43,068 residents in 2025, the eighth-largest gain of any U.S. metro. A company that needs CFO judgment can get it without adding a full-time salary at Seattle rates.
