Recent Tax Rate Changes in Washington
Washington's sales tax landscape shifted meaningfully over the past year, and if you haven't revisited your setup since early 2025, there's a good chance something has changed for your business. Here are the three updates worth knowing about:
Expansion of taxable services (Effective October 1, 2025): Under ESSB 5814, Washington broadened the sales tax base to cover additional services that were previously untaxed — including IT services, custom software, and certain digital services. If your business sells any of these, you're now required to collect and remit sales tax on them.
Seattle local tax increase (Effective January 1, 2026): Seattle added a 0.1% local sales tax increase to fund public safety programs. It's a small increment, but it raises the total combined rate for Seattle transactions, so your checkout math needs to reflect it.
Puyallup transportation tax increase (Effective April 1, 2025): Puyallup introduced a 0.2% transportation benefit district tax, pushing its combined rate higher. If you ship to or sell in Puyallup, that rate is no longer what it was a year ago.

State of Washington Sales Tax Calculator Example with Customers in Multiple Locations
An online retailer based in Oregon establishes economic nexus in Washington by exceeding $100,000 in annual sales or 200 transactions, requiring them to collect and remit sales tax for purchases made by Washington residents. The retailer makes sales to customers in multiple cities, each with different local tax rates.
Detail | Description |
|---|---|
Business | Online retailer based in Oregon with economic nexus in Washington. |
Customer Purchases | Customer A in Seattle $1,200 total, $800 taxable, $400 exempt (e.g., groceries or medications). Customer B in Spokane $900 total, $600 taxable, $300 exempt. Customer C in Tacoma $500 total, $400 taxable, $100 exempt. |
Customer Locations | Seattle 10.35% total sales tax. Spokane 9.1% total sales tax. Tacoma 10.3% total sales tax. |
Washington Sales Tax Calculations
Customer | Taxable Amount | Total Tax Rate | Total Tax Due |
|---|---|---|---|
Customer A | $800 | $800 × 10.35% = $82.80 | $82.80 |
Customer B | $600 | $600 × 9.1% = $54.60 | $54.60 |
Customer C | $400 | $400 × 10.3% = $41.2 | $41.2 |
Total Sales Tax Due in Washington
$84.00 (Customer A) + $53.40 (Customer B) + $40.80 (Customer C) = $178.20

Food and Beverage Tax in Washington
Food taxes in Washington aren't as straightforward as a blanket exemption or a flat rate — where your product falls on the taxable spectrum depends heavily on what it is and how it's sold. Here's how the state breaks it down:
Most grocery food is tax-exempt: Washington exempts food and food ingredients at the grocery level, meaning a customer buying raw produce, packaged goods, or basic staples won't pay sales tax at checkout. The exemption is designed around food you take home and prepare yourself.
Prepared food is taxable: The exemption stops the moment food is heated, combined into a meal, or served with utensils. A restaurant entrée, a deli sandwich, or a hot item from a grocery counter all cross into taxable territory — the state treats these the same as any other retail sale.
Soft drinks and dietary supplements are taxable: These don't qualify for the grocery exemption even when sold on a supermarket shelf. If you sell either category, you're collecting sales tax regardless of the retail context.
Alcohol carries additional taxes: Spirits in Washington are taxed at 20.5% plus a per-liter tax, stacked on top of the standard sales tax rate. It's one of the heavier alcohol tax structures in the country, so if you sell spirits, the combined burden is worth knowing precisely.
Food/Beverage Type | Taxable? | Notes |
Raw groceries and staples | No | Exemption covers food you buy and prepare at home |
Prepared food | Yes | Anything heated, combined into a meal, or served with utensils |
Soft drinks | Yes | No exemption, even in a grocery store context |
Dietary supplements | Yes | No exemption, regardless of where they're sold |
Spirits/alcohol | Yes + additional | 20.5% spirits tax plus a per-liter tax, on top of standard sales tax |
Excise Taxes in Washington
Washington's tax system is built differently than most states. Without a corporate income tax or personal income tax, the state relies heavily on excise taxes: charges applied to specific transactions, goods, and activities rather than earnings. Here's what that means in practice:
The business & occupation (B&O) tax
The B&O tax is the one most businesses run into first, and it catches a lot of out-of-state sellers off guard. Washington taxes your gross receipts: total revenue before any deductions for operating costs, payroll, or cost of goods. The rate varies by business classification, but it applies even if your business isn't profitable that year.
Real estate excise tax (REET)
Selling property in Washington triggers REET, which is typically paid by the seller at closing. The rate scales based on the sale price of the property, and local jurisdictions can layer additional amounts on top of the state rate.
Capital gains tax classified as an excise tax
Since 2022, Washington taxes the sale or exchange of long-term capital assets under a capital gains excise tax, rather than treating it as a traditional income tax.
In effect since | 2022 |
What’s taxed | Sale or exchange of long-term capital assets (stocks, bonds, business interests) |
Rate | 7% on gains above $262,000 (annually adjusted) |
Classification | Excise tax, not income tax, a distinction Washington has defended in court |
Other excise taxes to know
Washington also imposes excise taxes across a broad range of goods and industries.
Fuel, cigarettes, spirits, cannabis, and motor vehicles each carry their own rate structures.
Beyond individual goods, certain industries like public utilities and rental car companies face sector-specific excise taxes that operate separately from the general sales tax system.
Prepaid Sales Tax Rates for Fuel Products in Washington
Washington handles fuel taxation differently from most consumer goods. Rather than collecting sales tax at the pump, the state pulls it earlier in the supply chain at the distributor level, so by the time fuel reaches the consumer, the tax is already baked into the price.
How the rates break down
The current state fuel tax rates run from July 1, 2025 through June 30, 2026:
Fuel Type | State Tax | Combined State + Federal |
Gasoline | $0.554 per gallon | $0.738 per gallon |
Diesel | $0.584 per gallon | $0.828 per gallon |
These are flat per-gallon charges, not percentages of the sale price, so the tax burden doesn't shift with fluctuating fuel costs.
When retail sales tax still applies
The prepaid structure has one notable exception. If fuel is used off-highway for purposes like farming equipment, boats, or construction machinery, standard retail sales tax can apply instead of the fuel excise taxes. Whether that triggers a tax liability or a refund depends on the specific exemption your use case qualifies for.
Discretionary Local Sales Taxes in Washington
Washington's 6.5% state sales tax rate is just the starting point. On top of that, local governments can layer their own taxes, which is why the combined rate varies from one city or county to the next and why two businesses in the same state can be charging noticeably different rates.
What local governments can add
Cities and counties can impose up to 1.0% in unrestricted local sales tax, typically structured as two separate 0.5% components that can be used for general government purposes. Beyond that base, jurisdictions can approve additional targeted taxes, usually in the 0.1% to 0.3% range, tied to specific programs:
Public safety and law enforcement
Transportation and transit projects
Housing and mental health programs
These additions are why a city like Seattle carries a higher combined rate than a smaller municipality with fewer voter-approved levies.
Destination-based collection
The local rate that applies to a transaction is determined by where the customer receives the product or service, not where your business is located. If you ship to a customer in Tacoma, you charge Tacoma's combined rate. If they pick it up at your location in Spokane, you charge Spokane's rate. Getting the destination right is as important as knowing the rate itself.
Is Washington a Streamlined Sales Tax State? (New)
Yes. Washington has been a full member of the Streamlined Sales Tax (SST) program since July 1, 2008, meaning its laws comply with the Streamlined Sales and Use Tax Agreement (SSUTA), a multi-state effort to make sales tax administration more consistent and manageable across state lines.
What SST membership means in practice
For businesses selling across multiple states, SST membership matters because it standardizes the things that typically create compliance headaches: product definitions, sourcing rules, and filing requirements.
When states agree on the same definitions, you spend less time figuring out whether a product is taxable differently depending on which state you're selling into.
Washington's SST membership also means businesses can register in all SST member states through a single registration system rather than filing separately with each one.
From there, Certified Service Providers (CSPs) can handle tax calculation and filing automatically, which is particularly useful for high-volume sellers.
Destination-based sourcing
As part of its SST compliance, Washington applies destination-based sourcing: tax is calculated based on where the customer receives the product, not where the seller is located.
This is consistent with what was covered in the local taxes section above, and it applies across the board for both state and local rate determination.
FAQs

Sales Tax Nexus in Washington
Sales tax nexus in Washington establishes a business's obligation to collect and remit sales tax, triggered by physical presence, economic activity, or relationships with in-state entities.
Type of Nexus | Description | Threshold/Criteria |
|---|---|---|
Physical Nexus | Created by having a physical presence in Washington, such as a location, employees, or inventory. | Office, warehouse, storefront, or employees operating in Washington. |
Economic Nexus | Triggered by making substantial sales into Washington, even without a physical presence. | More than $100,000 in gross retail sales annually into Washington. |
