Updated: Sep 2026
Seattle business owners have another number to keep in mind when they’re calculating what customers will pay: 10.55%.
That’s Seattle’s current combined sales tax rate as of 2026, following the addition of a new 0.1% local sales and use tax for public safety programs. The increase took effect January 1, 2026, after Washington lawmakers authorized cities to impose the additional tax.
The new tax is expected to generate approximately $39 million per year for Seattle. The city’s 2026 budget directs that money toward public safety and related programs, including additional 911 call takers, Community Assisted Response and Engagement (CARE) crisis responders, firefighters, overdose response, diversion programs, and substance-use treatment.
For consumers, an extra one-tenth of one percent may not sound like much.
For businesses, however, any change to the sales tax rate is worth understanding — particularly if you sell taxable goods or services directly to Seattle customers.
What Is Seattle’s Public Safety Sales Tax?
Washington’s 2025 legislation authorized local jurisdictions to increase their local sales and use tax by 0.1% for public safety programs.
Seattle adopted the increase, and it became effective January 1, 2026.
The tax applies to taxable retail sales and services in Seattle. It also affects use tax in situations where taxable purchases are made without the appropriate sales tax being collected.
As a result, Seattle’s combined sales tax rate is currently 10.55%.
That figure includes the Washington state sales tax as well as state and local components. The exact rate can vary by location and transaction, so businesses should use Washington’s current tax-rate lookup rather than relying on an old rate chart when calculating tax.
How Much Difference Does 0.1% Really Make?
On an individual purchase, not much.
The additional tax is one dollar for every $1,000 of taxable sales.
For example, a $25,000 taxable purchase would generate an additional $25 in sales tax compared with the previous rate.
A $100 purchase would add just 10 cents.
But businesses that process thousands of taxable transactions don’t experience the change just once.
A retailer with $1 million in taxable Seattle sales would collect approximately $1,000 more in sales tax because of the 0.1% increase.
That doesn’t mean the business is making or losing $1,000. Sales tax collected from customers generally isn’t business revenue. The business is collecting it and remitting it to the appropriate tax authorities.
That’s an important distinction when you’re looking at your company’s financial statements.
The Sales Tax Isn’t Your Business’s Money
This is one of the most important things for a small business owner to understand about sales tax.
Suppose your Seattle business sells a taxable product for $100.
At a 10.55% sales tax rate, the customer pays $110.55.
That extra $10.55 generally isn’t $10.55 of revenue for your business.
You’re collecting the tax from the customer and then remitting it to the state and local tax authorities.
In other words, don’t look at your bank account and think:
“Sweet. I made $110.55.”
You made a $100 sale.
The remaining $10.55 is money you’ve collected for taxes.
This distinction becomes especially important when sales volume increases. Businesses that don’t properly separate sales-tax collections from operating cash can accidentally spend money that ultimately needs to be remitted.
Your accounting system should make the distinction clear.
Will the Higher Sales Tax Hurt Seattle Businesses?
The answer depends heavily on the type of business.
A business selling primarily to Seattle customers may notice different effects than a company selling primarily to customers outside the city.
And a business selling a $5 product faces a different practical situation from one selling $25,000 products or services.
For many transactions, the additional 0.1% is unlikely to dramatically change a customer’s purchasing decision on its own.
But sales tax is only one piece of the broader cost equation.
Seattle businesses are also dealing with labor costs, commercial rents, insurance, supplies, utilities, transportation, regulatory requirements, and other expenses.
That means even relatively small changes can become relevant when a business is already operating on a narrow margin.
The important thing is to look at your actual numbers rather than assuming that the tax increase will either be meaningless or catastrophic.
What About Customers Shopping Outside Seattle?
This is where location can matter.
Seattle’s 10.55% combined sales tax rate doesn’t apply simply because a business owner lives in Seattle.
Sales-tax obligations generally depend on the location of the taxable sale and the applicable sourcing rules.
A Seattle retailer selling something to a customer in another jurisdiction may therefore need to determine the appropriate tax rate based on where the transaction is sourced.
This is particularly important for businesses that sell online.
If you’re operating a Seattle business with customers throughout Washington, don’t simply put “10.55%” into your ecommerce platform and assume you’re finished.
Washington has a number of local sales-tax jurisdictions, and the appropriate rate can depend on the transaction’s location.
The Washington Department of Revenue maintains a current local sales-tax rate table and tax-rate lookup tool for this reason.
What About Restaurants, Retailers, and Other Consumer Businesses?
Businesses that routinely collect sales tax from customers are the ones most likely to notice the practical impact of the rate change.
Restaurants, retail stores, entertainment businesses, and other consumer-facing companies should make sure their point-of-sale systems are using the correct current rate.
If your POS system is still configured for an old Seattle rate, you could wind up collecting too little tax.
That’s not something you want to discover after you’ve already completed thousands of transactions.
The same applies to ecommerce systems, invoicing software, accounting platforms, and manually generated invoices.
If your business has multiple locations, make sure the tax settings aren’t simply copied from one location to another.
The correct rate can depend on where the taxable transaction occurs.
What About Service Businesses?
This gets a little more complicated because Washington has significantly expanded its sales-tax rules for certain services.
Beginning October 1, 2025, Washington made a number of previously nontaxable services subject to retail sales tax, including certain IT services, custom website development, software-related services, advertising and marketing services, temporary staffing, and security services.
That means a Seattle business providing one of these newly taxable services may have two separate things to think about:
- Washington’s expansion of which services are subject to sales tax.
- Seattle’s local sales-tax rate.
If your business started collecting sales tax because of the 2025 service changes, make sure your invoicing and accounting systems are also using the correct Seattle rate when applicable.
And if you operate in multiple cities or serve customers throughout Washington, don’t assume every customer should be charged the same rate.
Should You Raise Your Prices?
Not necessarily.
This is an important distinction.
A sales-tax increase doesn’t automatically mean you need to increase the underlying price of your product or service.
Sales tax is generally added on top of the selling price.
If you previously sold something for $100 and the applicable sales tax increased by 0.1%, your new customer-facing total may simply be slightly higher because of the tax.
That’s different from raising the price of the product itself from $100 to $101.
Whether you should increase your prices for other reasons is a separate business decision.
If your costs have increased significantly — whether because of wages, rent, insurance, supplies, B&O taxes, or other expenses — that’s a reason to review your pricing.
But don’t automatically treat a sales-tax increase as a reason to increase your base prices.
Seattle’s Budget Situation Is Bigger Than the Sales Tax
It’s also important to put the public safety sales tax into the broader context of Seattle’s finances.
Seattle’s 2026 budget was balanced, but the city is dealing with a structural budget problem that extends beyond a single year’s budget.
In July 2026, Seattle City Council member Bob Kettle described the city’s projected deficit for the following year as approximately $175 million, with larger deficits expected beyond that.
Then, on September 22, 2026, Mayor Katie Wilson released her proposed 2027–28 budget. Her administration described an inherited structural General Fund deficit of approximately $175 million and proposed reductions and other changes intended to address the city’s longer-term fiscal imbalance.
That means the public safety sales tax is only one part of Seattle’s much larger budget conversation.
For business owners, it’s worth keeping an eye on future changes to local taxes, fees, business regulations, and city programs rather than treating the 0.1% increase as an isolated event.
There’s Another Seattle Tax Change Businesses Should Know About
If you’re running a Seattle business in 2026, the public safety sales tax isn’t the only tax change worth knowing about.
Seattle also changed its Business & Occupation (B&O) tax structure beginning January 1, 2026.
The city’s B&O tax liability threshold increased from $100,000 to $2 million, and businesses can claim a $2 million standard deduction. At the same time, Seattle increased B&O tax rates for the classifications that remain subject to the tax.
That means some smaller businesses that previously had Seattle B&O tax liability may now fall below the tax threshold.
But businesses shouldn’t assume that “I make less than $2 million, so I don’t have to do anything.”
Seattle still has business-license and filing requirements, and the city’s rules distinguish between the tax threshold and the requirement to report business activity.
If you haven’t reviewed your Seattle business tax obligations for 2026, it’s worth doing so.
What Should Seattle Small Business Owners Do?
The good news is that you don’t need to reinvent your business because of a 0.1% sales-tax increase.
You do, however, want to make sure your systems are accurate.
Start with your point-of-sale or invoicing system.
Make sure it is calculating the correct current rate for Seattle transactions.
If you sell online or have customers in multiple Washington jurisdictions, verify that your software is determining the appropriate tax based on the transaction rather than simply applying Seattle’s rate to everything.
Then look at your bookkeeping.
Make sure sales tax collected is recorded separately from your actual revenue.
Finally, review your Seattle business tax obligations separately from your Washington state tax obligations. Seattle’s B&O tax and Washington’s B&O tax are different taxes with different rules.
What If You Operate Outside Seattle?
Don’t assume you can simply compare your sales tax rate with Seattle’s and determine which location is “better” for your business.
Washington has numerous local sales-tax jurisdictions, and rates change over time.
If you’re deciding where to locate a business, sales tax is only one consideration.
You also need to consider commercial rent, labor costs, customer demographics, transportation, local B&O taxes, licensing requirements, property taxes, and whether your customers are actually willing to travel to your location.
For an established business, moving locations solely to avoid a fraction of a percentage point in sales tax may not make economic sense.
For a new business choosing between locations, however, the cumulative effect of local taxes and operating costs is worth modeling before signing a lease.
The Bottom Line
Seattle’s public safety sales tax is no longer a proposal. The additional 0.1% took effect January 1, 2026, bringing Seattle’s current combined sales tax rate to 10.55%.
The city expects the tax to generate roughly $39 million annually, with 2026 budget allocations supporting CARE crisis-response teams, 911 staffing, firefighters, overdose response, diversion programs, and substance-use treatment.
For most small businesses, the biggest practical issue isn’t whether that additional 0.1% will make or break the company.
It’s making sure you’re charging the correct rate, separating sales tax from revenue, and understanding how Seattle’s local taxes fit into your overall business costs.
And if you’re running a Seattle business in 2026, don’t stop at the sales-tax rate. Seattle’s B&O tax structure also changed this year, while the city continues to work through a significant structural budget deficit.
Tax planning at the local level matters.
The difference between a smooth tax year and a nasty surprise often comes down to whether you reviewed the rules before the bill arrived.
