The Problems We Solve for Washington Business Owners
Washington's tax environment is genuinely different from every other state. Here's what we see most often — and what we do about it.
When the Bank Says No — And the Books Are Why
Picture a Spokane general contractor — two crews, about $420,000 in revenue, busy enough that the owner is on job sites six days a week. He goes to Washington Trust Bank for a $70,000 equipment line to buy a skid steer and a trailer. The bank says no. Not because the business isn't making money — it probably is. But the books are a mess. Business expenses are mixed with personal spending. There's no job costing. The P&L looks like a disaster even though cash is coming in. This is one of the most common situations we see with small contractors across Eastern Washington and the Inland Northwest.
B&O tax is owed on gross receipts — regardless of profitability.
Clean financials unlock things that messy books never can: a readable P&L that shows true profitability by job, a balance sheet that supports a credit application, and a clear picture of what the business actually earns. A Spokane contractor at $420K with proper job costing and clean separation between business and personal is a fundable business. The same contractor with mixed books isn't — regardless of how busy the crews are. The work is the same. The financial picture is completely different.
Bookkeeping ServicesThe Books Looked Fine. They Weren't.
A client came to us after working with a cheaper bookkeeping service for several years. On the surface, the books looked okay — revenue was being recorded, expenses were being tracked. But when we reviewed the books in detail, we found two problems that had been compounding quietly for years. First: the owner had been making capital contributions to the business — putting their own money in to cover slow months — and those contributions had been coded as revenue. That inflated taxable income every single year. The owner was paying income tax on money they had already paid tax on personally.
The books looked fine. But they were paying taxes on money they had already paid tax on -- for years. Over $60,000 in taxes the owner was prepared to keep paying.
Second: equipment purchases — a skid steer, a trailer, a work truck — had been coded as owner contributions instead of fixed assets. That meant the business never took the depreciation deductions it was entitled to. Thousands of dollars in write-offs, gone. When we corrected the coding, the picture changed significantly. A cheaper bookkeeper records what happens. A good one understands what it means — and catches the difference between a capital contribution and revenue, between an asset purchase and an expense. The owner was prepared to keep paying. They didn't have to.
Tax PlanningFrom $600K to $3M — Without the Owner Having to Be There Every Day
Here's what a Tri-Cities construction and remodeling company at $600,000 in revenue typically looks like: the owner is doing everything — quoting jobs, managing crews, handling customer calls, and trying to keep up with the books on Sunday nights. He knows he's leaving money on the table but doesn't know where. He can't take a vacation. He can't hire a foreman because he doesn't know if he can afford one. He is the bottleneck in his own business.
The path from $600K to $3M isn't about working harder — it's about building the financial infrastructure that lets the business run without the owner being the answer to every question. That starts with a real P&L that shows which services are actually profitable. Then a simple dashboard: revenue by service line, labor cost as a percentage of revenue, a 13-week cash flow forecast. With that foundation, an owner can make decisions based on numbers, not gut feel — and eventually hire a foreman, step back from day-to-day operations, and grow intentionally.
Controller ServicesWhen the Money Comes In Three Months a Year
The Yakima Valley is one of the most productive agricultural regions in the country, and the businesses that serve it — equipment dealers, cold storage operators, processors, suppliers, and contractors — live and die by the harvest calendar. Revenue arrives in a handful of intense months, then the bank balance drifts down for the rest of the year. Owners manage it by feel, watching the account and hoping it lasts. That works until the year it doesn't — a slow harvest, a late payment from a processor, an equipment failure — and suddenly there's no cushion and no warning.
A bank balance tells you where you are. A forecast tells you where you are headed -- so a seasonal business knows in August what February looks like.
Seasonal businesses don't need more reports. They need to see around the corner. We build a rolling 13-week cash flow forecast calibrated to Washington's harvest and processing cycles, so an owner knows in August what February looks like — and can line up a seasonal line of credit, time equipment purchases, and ride out a slow stretch without panic. A bank balance tells you where you are. A forecast tells you where you're headed.
Doing Business on Both Sides of the WA/ID Line
Eastern Washington's economy doesn't stop at the Idaho border. Spokane-area contractors take jobs in Coeur d'Alene, suppliers ship across the state line, and owners hire employees who live in one state and work in the other. The result is a quiet multi-state problem most local accountants never flag: Washington's B&O gross receipts tax and Idaho's income tax pulling in opposite directions, payroll nexus questions, and apportionment decisions that get made by accident instead of on purpose. Operating in both states without proper multi-state filings builds up exposure year after year.
Multi-state nexus is something we work with regularly for businesses across the Inland Northwest. We coordinate the B&O tax, Idaho income tax apportionment, payroll nexus, and entity structure decisions across both states so nothing falls through the cracks — and if you've already been operating in both states without proper filings, we assess the exposure and get you back into compliance before it becomes a problem.
Controller ServicesMountain West Roots.

What Makes Washington's Tax Environment Unique
“No income tax” is the headline — but the full picture is more complex.
Business & Occupation Tax
Washington's B&O tax is a gross receipts tax — you pay it on revenue regardless of profitability. Rates vary by classification: 1.5% for services, 0.471% for retail, 0.484% for manufacturing and wholesale. Getting your classification right, managing deductions, and using the Small Business B&O Credit threshold are all planning opportunities most Washington businesses miss.
No Income Tax — But...
Washington's lack of a state income tax is often cited as a business advantage. But between B&O tax, sales tax (6.5% + local), L&I, and PFML, Washington's total tax burden on small businesses is often comparable to or higher than neighboring states with income taxes. The planning opportunities are different — not necessarily better.
Employer Compliance Burden
Washington's PFML program requires employer contributions of 0.74% on wages up to the Social Security wage base. Employers with 50+ employees pay a portion; smaller employers may be exempt from the employer share but must still withhold the employee portion. Misclassifying workers or miscalculating the employer share is a common and costly compliance error.
Washington's L&I rates are set by risk classification and vary dramatically by industry. Misclassifying workers — even unintentionally — can result in significant back premiums and penalties. We review L&I classifications for every new Washington client as part of onboarding.
Serving Washington Businesses Statewide
From the Inland Northwest to the coast — same depth of financial expertise regardless of location.
Spokane & Inland Northwest
Spokane is the economic hub of Eastern Washington and the Inland Northwest. Construction, healthcare-adjacent services, professional services, and trades businesses are all growing — and most are running on financial systems built for a smaller version of themselves. The bi-state economy with Idaho adds multi-state complexity that most local accountants don't handle well.
Tri-Cities (Kennewick, Richland, Pasco)
The Tri-Cities is one of Washington's fastest-growing metros — driven by energy, agriculture, construction, and a strong professional services economy. Businesses here often have strong revenue but face significant cash flow complexity, B&O tax exposure, and underdeveloped financial infrastructure.
Yakima Valley
The Yakima Valley is one of the most productive agricultural regions in the country. Agriculture-adjacent businesses — equipment dealers, cold storage operators, processors, suppliers, and contractors — face dramatic seasonal cash flow swings and need real forecasting, not just a bank balance check.
Bellingham & Whatcom County
Bellingham and Whatcom County have a diverse economy — trades, manufacturing, hospitality, and a growing professional services sector. Proximity to the Canadian border adds cross-border complexity for some businesses. Construction and remodeling are booming.
Wenatchee & North Central Washington
Wenatchee and the surrounding region are anchored by tree fruit agriculture, outdoor recreation, and a growing trades economy. Seasonal revenue patterns tied to apple and pear harvest are significant, and businesses here often need better cash flow management and banking readiness.
Walla Walla & Southeast Washington
Walla Walla's wine industry and agriculture-adjacent economy create unique financial challenges — seasonal revenue, complex entity structures for vineyard and winery operations, and the need for financial systems that can support growth and eventual exit or succession planning.

Business Turnaround & Financial Advisory
The Foundation Has to Be Right Before Strategy Matters
Most Washington businesses have a tax preparer. Very few have clean books, compliant payroll, and real-time financial visibility. That's the foundation we build first — because without it, every other service is built on sand.
Clean Books, Every Month
Washington businesses face B&O tax on gross receipts, PFML compliance, and L&I rate management — all of which require accurate, up-to-date books to manage correctly. We maintain reconciled financials every month using QuickBooks Online or Xero, categorized for your industry and ready for your CPA, your bank, or your partners at any time.
Washington Payroll Done Right
Washington has the highest minimum wage in the country, mandatory Paid Family & Medical Leave (PFML), and L&I workers' comp rates that vary by job classification. Getting any of these wrong creates real liability. We process payroll accurately and manage all Washington-specific compliance requirements so you're not exposed.
Washington Has No Income Tax. But the B&O Tax Is Relentless — and Most Businesses Aren’t Managing It.
The B&O tax applies to gross receipts — not profit. A $4M construction company with 8% margins pays B&O on the full $4M. Without proper financial infrastructure, this tax erodes cash flow invisibly until it becomes a crisis.
Our Controller and fractional CFO services give Washington businesses the B&O planning, month-end close, and management reporting that makes the no-income-tax advantage actually work in your favor.
B&O Tax Planning
Gross receipts tracking, classification review, and quarterly estimates.
Month-End Close
Accurate, timely financials every month — not just at tax time.
Management Reporting
P&L, balance sheet, and KPI dashboards built for decisions.
Lender & Investor Ready
Books at the standard banks and investors require — before you need them.
B&O Tax Owed vs. Revenue — By Classification
Washington’s B&O tax is calculated on gross receipts — not net income. Rates vary by business classification. A services firm at $3M revenue owes $51K in B&O alone, before income tax equivalents.
B&O rates: Services 1.7%, Retail/Construction 0.5%. Actual rates vary by classification. Source: WA Dept. of Revenue.
