Most services you buy or sell in Washington are not taxable. The state only charges retail sales tax on services it has specifically written into the law as retail sales, so if a service isn’t on that list, no sales tax applies. The services that are not taxable in Washington State include professional work from attorneys, doctors, and accountants, hair care, consulting, healthcare, education, routine janitorial work, and custom creative or IT work driven by human effort.1Washington Department of Revenue. Services Subject to Sales Tax
The Default Rule for Services in Washington
Washington flips the usual expectation. Physical goods are taxable unless a specific exemption applies. Services work the opposite way: a service is not subject to retail sales tax unless a statute or rule explicitly identifies it as a retail sale.1Washington Department of Revenue. Services Subject to Sales Tax
That means the practical question isn’t “is my service exempt?” It’s “did the legislature put my service on the taxable list?” If the answer is no, you don’t collect sales tax, and you don’t pay it when you hire the provider. The statewide sales tax rate is 6.5%, with local additions pushing combined rates as high as 10.55% in parts of Seattle, so the distinction has real weight on larger invoices.2Washington Department of Revenue. Retail Sales Tax
Professional Services
Services provided by attorneys, physicians, dentists, architects, engineers, and accountants are not subject to retail sales tax.1Washington Department of Revenue. Services Subject to Sales Tax The work reflects human expertise and judgment, and Washington does not treat that as a retail transaction. Even when a professional delivers the final result electronically, the service stays non-taxable as long as the real work is human effort rather than automated software output.
Hair Care and Most Personal Services
Haircuts, coloring, styling, and hair removal are not subject to sales tax. The Department of Revenue classifies hair care income under the Service and Other Activities B&O category, and providers do not collect retail sales tax on those charges.3Washington Department of Revenue. Hair Care Including Hair Removal
Not every personal service in that neighborhood is treated the same way, though. Tanning, tattooing, personal training at a gym, and Turkish or steam baths are all taxable retail services.1Washington Department of Revenue. Services Subject to Sales Tax It’s worth checking the Department of Revenue’s list before assuming a salon-adjacent service is exempt.
Consulting, Healthcare, and Education
Management consulting, business advisory work, healthcare services, and most education and training programs are not retail sales and carry no sales tax. If you hire a consultant to review your operations or pay a tutor for private lessons, those charges are sales-tax-free.
Routine Janitorial Services
Regular janitorial work done by a commercial cleaning company is not subject to sales tax. The Department of Revenue defines “janitorial services” as the routine, repetitive tasks a commercial janitor normally performs: cleaning and waxing floors, washing windows, dusting, cleaning walls and woodwork, cleaning rugs and drapes in place, and disposing of trash.4Washington Department of Revenue. Common Janitorial Services
Work outside that routine list is treated as specialized cleaning and becomes a taxable retail service. Pressure-washing a building exterior, stripping and refinishing a floor as a one-time project, or deep-cleaning a commercial kitchen after a renovation would all fall on the taxable side.
Custom Creative and IT Work
Custom web design, graphic design, software development, and similar creative or IT work are generally not subject to sales tax when the provider is doing bespoke work driven by human effort.1Washington Department of Revenue. Services Subject to Sales Tax The qualifier is “custom.” If a human applies skill and judgment after the client requests the work, it reads as a non-taxable professional service.
When Automated Delivery Makes a Service Taxable
This is where creative and IT providers often get surprised. Washington taxes “digital automated services,” defined as services transferred electronically that use one or more software applications. If a service is primarily delivered through automation rather than human effort, it is a taxable digital automated service even if the same underlying work would be exempt when done by hand.5Washington State Legislature. WAC 458-20-15503 – Digital Products
The test for staying non-taxable: more than 50% of the effort to perform the service must be human labor, and that human effort must have originated after the customer requested the service. The Department of Revenue measures this by averaging two factors. The first is the proportion of time spent on human effort versus total time. The second is the proportion of direct costs for human effort versus total direct costs. If the average exceeds 50%, the service is not a digital automated service and remains non-taxable.5Washington State Legislature. WAC 458-20-15503 – Digital Products
An engineer who runs calculations, applies professional judgment, and emails the report is providing a non-taxable professional service. A company that offers a self-service portal where customers pick a template and software generates the document with minimal human review is likely providing a taxable digital automated service. Same delivery format, different answer.
Services People Assume Are Exempt but Aren’t
A short list of services that commonly show up with sales tax on the invoice, because readers looking for what’s exempt need to know what isn’t.
Repair, Cleaning, and Alteration of Your Property
If someone repairs, cleans, installs, decorates, or otherwise alters your tangible personal property, the entire charge is subject to retail sales tax, including the labor. This applies even when no parts or materials are used.6Washington State Legislature. WAC 458-20-173 – Installation, Cleaning, and Repair Services A mechanic’s bill, a tailoring charge, furniture refinishing, or electronics repair all carry sales tax on the full amount.
Dry Cleaning and Laundry
Dry cleaning and laundry services provided to consumers are subject to retail sales tax, covering the laundering, cleaning, dyeing, and pressing of clothing, linens, curtains, and rugs.7Washington State Legislature. WAC 458-20-165 – Laundry and Dry Cleaning Services Laundry services sold to nonprofit healthcare facilities are exempt.
Construction and Landscaping
Construction work for a property owner is a retail sale. A contractor building an addition, remodeling a kitchen, or repairing a roof collects sales tax on the entire contract price: labor, materials, subcontractor costs, and equipment rentals.8Washington Department of Revenue. Construction Tax Matrix Landscaping and lawn maintenance follow the same rule, including mowing, pruning, and garden installation.1Washington Department of Revenue. Services Subject to Sales Tax Standalone landscape design, provided separately from any physical work, is a non-taxable professional service, but once the designer also does the planting the entire job becomes taxable.
Recreation and Lodging
Golf course fees, golf cart rentals, and similar facility-based recreation are subject to retail sales tax.9Legal Information Institute. Washington Administrative Code 458-20-183 – Recreational Services Hotels, motels, and short-term rental accommodations carry retail sales tax plus additional lodging-specific taxes, which can include a special hotel/motel tax, convention and trade center taxes in King County, and tourism promotion area charges.10Washington Department of Revenue. Lodging Taxes
No Sales Tax Doesn’t Mean No Tax
One important caveat for anyone selling a non-taxable service. Washington’s Business and Occupation tax is a gross receipts tax that applies to nearly every business operating in the state, regardless of whether the service itself triggers sales tax. There are no deductions for labor, materials, or other costs.11Washington Department of Revenue. Business and Occupation Tax A consulting firm whose services are completely free of sales tax still owes B&O on every dollar of revenue it brings in. If you’re a service buyer, this doesn’t affect what you pay at the register. If you’re a service provider, “non-taxable” refers only to the sales tax column on your invoice.
