Nonprofits in Washington State do pay sales tax. Federal 501(c)(3) status does not, on its own, exempt an organization from Washington’s retail sales tax, use tax, or Business and Occupation (B&O) tax. A nonprofit buying office furniture, computers, or cleaning supplies is treated as a consumer and owes tax the same way a for-profit business would.1Washington State Legislature. Washington Code 82.08.02087 – Exemptions — Digital Goods and Services — Purchased for Business Purposes There are exemptions, but they are narrow, activity-specific, and require the right paperwork at the point of sale.
When Your Nonprofit Is the Buyer
The default rule is simple: Washington imposes retail sales tax on every retail sale of tangible personal property, and a nonprofit buying supplies for its own operations is the consumer. There is no general charitable exemption.
If your organization buys something out of state or online and no Washington sales tax is collected, you owe use tax at the same rate directly to the Department of Revenue. The use tax closes the gap so out-of-state sellers don’t get a price advantage, and overlooked use tax is a common audit finding.
The Narrow Purchase Exemptions That Do Exist
A handful of statutory exemptions let specific types of nonprofits buy specific things tax-free. The organization carries the burden of proving it qualifies.
Artistic and Cultural Organizations
Under RCW 82.08.031, a qualifying arts or cultural nonprofit can buy certain items without paying sales tax. The organization must be a nonprofit corporation governed by a board of at least eight people, none of them paid employees, with assets irrevocably dedicated to artistic or cultural purposes and programs open to the public regardless of race, color, or national origin.2Washington State Legislature. WAC 458-20-249
The exemption covers objects of art, objects of cultural value, materials used to create artwork (but not the tools), and items used to display art or stage performances. General office supplies, building materials, and other operating purchases are not covered.2Washington State Legislature. WAC 458-20-249
Blood Banks and Tissue Banks
Qualifying blood banks and tissue banks are exempt from use tax on medical supplies, chemicals, and materials used in processing and distributing biological products. Construction materials, office equipment, administrative supplies, and vehicles are not included.3Washington State Legislature. Washington Code 82.12.02747 – Exemptions – Use of Medical Products by Qualifying Blood, Tissue, or Blood and Tissue Banks
Nonprofit Youth Organizations
A nonprofit youth organization meeting the definition in RCW 82.04.4271 is exempt from retail sales tax on sales of amusement, recreation, and personal services to its own members. Camp fees and recreation programs for members are typical examples.4Washington State Legislature. RCW 82.08.0291 – Exemptions – Sales of Amusement and Recreation Services or Personal Services by Nonprofit Youth Organization
Health and Social Welfare Organizations
Washington defines “health or social welfare services” broadly, covering health care, legal services for the indigent, weatherization assistance, home heating cost offsets for low-income households, and community services aimed at reducing poverty. Qualifying organizations may receive B&O tax exemptions and, in some cases, related sales tax relief on purchases tied to their programs.5Washington State Legislature. Washington Code 82.04.431 – Health or Social Welfare Organization Defined – Conditions for Exemption
When Your Nonprofit Is the Seller
Selling merchandise, charging admission, or providing retail services generally means collecting sales tax from the customer. Washington’s state rate is 6.5%, and local jurisdictions add their own, pushing combined rates as high as 10.4% in some areas.6Washington Department of Revenue. Sales and Use Tax Rates Organizations making taxable sales must register with the Department of Revenue, collect the tax, and remit it on a schedule tied to their volume. The Department publishes a searchable rate table for looking up the correct combined rate at any location.7Washington Department of Revenue. Local Sales and Use Tax Rate Table
The Fundraising Exemption and Its Limits
This is the one exemption most Washington nonprofits can actually use. Under RCW 82.08.02573, sales made during fundraising activities are exempt from retail sales tax, and under RCW 82.04.3651, the income from those activities is exempt from B&O tax. The exemption applies to organizations exempt under IRC Section 501(c)(3), (4), or (10), as well as certain unincorporated nonprofits meeting similar criteria.8Washington State Legislature. RCW 82.04.3651 – Exemptions – Amounts Received by Nonprofit Organizations for Fund-Raising Activities
The limit is what counts as “fundraising” in the first place. Running a thrift shop, bookstore, restaurant, or similar retail operation during regular hours at a fixed location does not qualify, even if every dollar supports the mission. That gets treated as a regular place of business and taxed normally. An annual auction, a seasonal bake sale, or a merchandise table at a special event, where the proceeds fund the organization’s purposes, does qualify.8Washington State Legislature. RCW 82.04.3651 – Exemptions – Amounts Received by Nonprofit Organizations for Fund-Raising Activities
Sales tax follows B&O here: if the income is exempt from B&O under RCW 82.04.3651, the sale is also exempt from retail sales tax.9Washington State Legislature. RCW 82.08.02573 – Exemptions – Sales by a Nonprofit Organization for Fund-Raising Activities
How to Actually Claim a Sales Tax Exemption
To buy something tax-free under one of the exemptions above, give the vendor a completed Buyer’s Retail Sales Tax Exemption Certificate at the time of purchase. The form asks for your organization’s full legal name, address, and Washington Unified Business Identifier (UBI) number, plus a check box identifying the specific legal basis for the exemption.10Washington Department of Revenue. Exemption Forms
The UBI is a nine-digit number that registers you across multiple state agencies. You get one by filing a Business License Application through the Department of Revenue.11Washington Department of Revenue. Business Licensing and Renewals FAQs
Keep every completed exemption certificate for at least five years. That’s the retention period Washington requires, and those records are what protect the exemption during an audit.12Washington Department of Revenue. Sales and Use Tax Exemptions Returns, account management, and most filings run through the My DOR online portal; organizations that can’t use it can file paper forms with the Department in Olympia.13Washington Department of Revenue.

What It Costs to Get This Wrong
Washington’s penalties for late or unpaid excise tax escalate on a fixed schedule under RCW 82.32.090:
- 9% if the tax is not received by the due date.
- 19% total if the tax remains unpaid at the end of the following month.
- 29% total if the tax is still unpaid at the end of the second month after the due date.
The minimum penalty is $5. If the Department issues a warrant to collect, another 10% is added. An organization that never registered for a tax account faces a 5% penalty on the tax due for the entire unregistered period, and the penalty for intentional evasion is 50%.14Washington State Legislature. RCW 82.32.090 – Late Payment – Disregard of Written Instructions – Evasion – Penalties
Misusing a resale certificate or reseller permit to skip sales tax on a purchase that doesn’t actually qualify also carries a 50% penalty on the unpaid tax. A nonprofit that claims an exemption it doesn’t qualify for is exposed to the same penalty structure.
Sales Tax Is Not the Only Tax to Watch
Two neighboring taxes catch nonprofit boards off guard, and silence here would be misleading.
Washington’s B&O tax applies to gross receipts, and nonprofit status alone is not an exemption. If your organization generates revenue, it probably owes B&O tax unless a specific statutory carve-out applies. Narrow exemptions exist for fundraising (RCW 82.04.3651), short-stay child care by property-tax-exempt churches (RCW 82.04.339), camp and conference centers on property-tax-exempt land (RCW 82.04.363), nonprofit credit and debt counseling (RCW 82.04.368), and sheltered workshops and group training homes receiving funds from the Department of Social and Health Services (RCW 82.04.385). B&O tax hits gross receipts, so a program that loses money on a net basis can still owe it.15Washington State Legislature. WAC 458-20-169
Property tax is separate again. Chapter 84.36 RCW provides exemptions for property used for character-building and social services, child day care centers, homes for the aging, emergency and transitional housing, nonprofit schools and colleges, and more. Each has its own conditions, and the organization has to apply through the Department of Revenue; the exemption is not automatic.16Washington State Legislature. Chapter 84.36 RCW – Exemptions
