Every few months an owner tells us the same story. Sales are up, the team is bigger, and somehow the bank balance feels smaller than it did a year ago. Nobody can say why. The books are “mostly done,” the tax return is “someone’s problem in March,” and the owner is making calls on gut feel.
That gap, between running a business and understanding its numbers, is where the right seattle accounting services close it. But which services? You don’t need all of them on day one, and you don’t want to pay for ones you won’t use. Here’s a way to sort it out.
Start with what’s different about Seattle
City and state business taxes
Washington has no state income tax, which sounds like a gift until you meet the Business and Occupation tax, a tax on gross receipts rather than profit. B&O is assessed on gross receipts with no deductions for labor, materials, or other costs. You can owe it in a month when you lose money. Washington charges its own B&O tax, and Seattle charges another. They are separate taxes and must be filed separately.
What changed in 2026
The city made a big change this year. Beginning January 1, 2026, the Seattle B&O threshold rose from $100,000 to $2 million. That’s good news for smaller businesses, but don’t relax yet. Businesses under the threshold must still complete and file their Seattle B&O returns. They also still need to renew their annual business licenses. A seattle accounting firm that treats the new threshold as “no filing needed” will hand you penalties.
Filing frequency can shift too, and the rules differ by business type, so confirm your own situation with the city or a CPA.
Payroll rules that stack up fast
Hire in Seattle and you inherit a long list. Washington Paid Family and Medical Leave premiums, the WA Cares program, state paid sick leave, and Seattle’s own rules, including a local minimum wage that adjusts each January. None of it is hard on its own. All of it together is a lot for an owner to track between sales calls.
Match support to your stage
Getting started
At this point you need a clean setup more than a big team. Open a business checking account and a business card, pick accounting software, build a short chart of accounts, and register for the right state and city licenses. Many owners skip this and pay later to untangle it. One careful afternoon saves months of cleanup.
Hiring your first people
Employees change everything. You need a payroll provider, proper worker classification, and a monthly habit of reconciling payroll reports to your books. This is usually the moment owners stop doing their own bookkeeping, since a payroll mistake costs far more than a miscoded lunch.
Seattle accounting services at this stage often mean a bookkeeper who also handles payroll reconciliation and sales tax filings, plus a CPA you can reach when a classification question comes up.
Opening a second location or product line
Two locations or two revenue streams means you need to see each one separately. Which one makes money? Which one is quietly losing it? Without location-level reporting, a strong store can hide a weak one for months. This is when forecasting and budgeting stop being nice extras.
Raising money, borrowing, or planning an exit
Lenders and investors want statements that reconcile, stay consistent month to month, and arrive on time. If you plan to sell someday, start preparing two years ahead. Clean books add value. Messy ones create discounts.
The four layers of support
Bookkeeping
The base layer. Transactions get categorized, accounts get reconciled to the penny, and statements arrive by a set day each month. Without it, nothing above works. Our opinion, and some advisors disagree: don’t hire a CFO until your books are accurate. Forecasts built on bad numbers are fiction with a nice font.
Tax planning and filing
Filing is a once-a-year event. Planning happens all year. A good CPA reviews your numbers before year-end, models big purchases and owner pay, and flags what you should do before December 31. Ask any CPA you consider for their license number and check it with the Washington State Board of Accountancy. It takes two minutes.
Payroll
Software like Gusto does the processing. Someone still has to reconcile it, review it, and keep up with rule changes. Decide who owns that job.
Fractional CFO guidance
A part-time CFO builds budgets and cash forecasts, reviews pricing and margins, and helps with financing decisions. It’s the layer that turns numbers into decisions.
When the CFO layer earns its fee
- You’re weighing a hire, a loan, or a new location
- Profit looks fine but cash feels tight
- A lender or investor asked for a forecast
- You can’t say which product or service makes the most money
A seattle accounting firm that offers all four layers under one roof can cut handoffs, but you can also assemble the pieces from different providers. Either works, as long as someone owns accuracy from top to bottom.
How to pick the right mix
Write down what’s broken today. Late books point to bookkeeping. A surprise tax bill points to planning. Tight cash and big decisions point to CFO support. Then ask two or three providers for a written scope, a sample monthly package with client details removed, and a stated response time. Ours is within 24 hours.
Ask who actually does the work. At some firms a senior person sells and a junior one delivers. That’s fine if you know it up front. You should also test them. Send a real question by email and see how fast and how well they answer.
We haven’t found a clean rule for when to switch from a freelancer to a firm, since it depends on how much backup you need. A freelancer is often cheaper and more personal. A firm survives a sick week.
Local presence helps somewhat. Seattle’s tax rules reward familiarity, so seattle accounting services from a team that files Seattle returns regularly can save you from small mistakes. Still, remote work is routine for most books and returns.
What it costs
Get fees in writing, broken out by service. For reference, our monthly engagement for bookkeeping, accounting, and fractional CFO support starts at $550 a month. Tax preparation starts at $125 an hour, CPA work at $250 an hour, and payroll at $125 an hour. “Starting at” matters because your transaction volume and the state of your books move the final number.
Our free financial analysis takes under an hour. We look for your main issues and sketch a roadmap, with no obligation. We’re a boutique seattle accounting firm, so judge our view with that in mind. The cheapest quote, in our experience, usually buys you a cleanup bill later.
Conclusion
Write down your top three money headaches today, then match each to one of the four layers. Ask two providers to show you how they’d handle each one, with a sample deliverable and a written scope. Whichever seattle accounting firm answers with specifics, including what they don’t know yet, deserves a second meeting.
FAQs
Do I still need to file Seattle B&O returns if I’m under the $2 million threshold?
Yes. Under the city’s guidance, businesses below the threshold still file returns, often showing no tax due, and renew their business license each year. Confirm your filing frequency with the city.
When should a Seattle business hire its first bookkeeper?
Usually when your books run more than a month behind, when you add employees, or when your evenings go to fixing categories. Those signs show up before problems get expensive.
What do Seattle accounting services usually include?
Typically bookkeeping, payroll support, tax planning and filing, and sometimes fractional CFO work. Ask each provider for a written scope that lists inclusions and exclusions.
Do I need a CPA, or is a bookkeeper enough?
A bookkeeper keeps your records clean. A CPA becomes important for tax planning, return preparation, and representation if the IRS or state asks questions.
How do I know if I’m ready for a fractional CFO?
If you’re facing larger decisions than your records can support, such as financing, a second location, or pricing changes, you’re likely ready. Make sure your books are accurate first.
