The sales tax rate in Ferndale, Washington is 8.8%. That total combines Washington’s 6.5% state retail sales tax with 2.3% in local taxes that fund city, county, transit, and public safety services in Ferndale and Whatcom County.1Washington State Legislature. RCW 82.08.020 – Tax Imposed, Retail Sales, Retail Car Rental Because Washington has no state income tax, sales and use taxes do more of the heavy lifting here, and the rules reach further than many residents expect.
You can verify the current combined rate for any Washington address through the Department of Revenue’s online tax rate lookup tool.2Washington Department of Revenue. Sales and Use Tax Rates
What the 8.8% Applies To
The rate covers tangible personal property sold to end users: furniture, electronics, clothing, vehicles, building materials, and essentially anything you can touch. The Department of Revenue defines taxable property as anything that “can be seen, weighed, measured, felt, or touched.”3Washington Department of Revenue. Retail Sales Tax
Services tied to physical property are also taxable. Construction labor, equipment repair, landscaping, and cleaning services all carry the full 8.8% when performed in Ferndale.3Washington Department of Revenue. Retail Sales Tax As of October 1, 2025, Washington expanded the list of taxable services to include advertising, IT services, temporary staffing, custom software development, and live presentations or training.4Washington Department of Revenue. Digital Products Including Digital Goods
Digital products are taxable too. Downloads, streaming subscriptions, music, movies, e-books, cloud-based software, and digital automated services all fall under the rate. It doesn’t matter whether you download or stream, or whether your access is permanent or temporary.4Washington Department of Revenue. Digital Products Including Digital Goods
Shipping is part of the deal. Sellers can’t strip out delivery charges to shrink the taxable amount; the delivery fee is taxed at the same rate as the product. If the item is taxable, so is the shipping. If the item is exempt, the shipping is exempt. Mixed shipments get split proportionally by price or weight.5Washington Department of Revenue.

What’s Exempt
Grocery Food
Most food and food ingredients sold for home consumption are exempt. That covers produce, meat, dairy, bread, and canned goods. It does not cover prepared food, soft drinks, dietary supplements, or bottled water. “Prepared food” generally means anything the seller heated, combined for sale as a single item, or sold with eating utensils.6Washington State Legislature. WAC 458-20-244 – Food and Food Ingredients
Raw chicken from the grocery aisle is exempt. A rotisserie chicken from the deli counter is taxable. Orange juice is exempt; a sweetened iced tea usually isn’t.

Business Exemptions
Businesses buying inventory for resale can use a Reseller Permit from the Department of Revenue to skip sales tax at purchase. The tax then shifts to the final consumer when the business sells the item. The permit only covers items that will actually be resold in the regular course of business. Misusing a reseller permit on personal purchases triggers the unpaid tax plus a 50% penalty, even without any intent to defraud.9Washington Department of Revenue. Reseller Permits
Manufacturers reporting under a manufacturing B&O classification can also buy qualifying machinery and equipment without paying sales tax. The equipment must be used directly in manufacturing, research and development, or testing, and dedicated to that purpose more than 50% of the time. Repair parts and installation labor are included.10Washington Department of Revenue. Manufacturer’s Sales/Use Tax Exemption for Machinery and Equipment (M&E)
Use Tax on Online and Out-of-State Purchases
Use tax is the back-end match to sales tax. It applies at the same 8.8% rate in Ferndale and is owed by the buyer when sales tax wasn’t collected at purchase. The most common trigger is an online or out-of-state purchase where the seller didn’t charge Washington sales tax.11Washington Department of Revenue. Use Tax
Most large online retailers already collect the 8.8% on shipments to Ferndale addresses, because any remote seller with more than $100,000 in combined gross receipts sourced to Washington in the current or prior year must register and collect.12Washington Department of Revenue.

- Wholesaling: 0.484% of gross receipts
- Service and other activities: 1.5% of gross receipts
Businesses with multiple activities may need to report under several classifications.14Washington Department of Revenue.
