How Washington State Advertising Tax Works After ESSB 5814

Washington’s advertising tax changed on October 1, 2025. Under ESSB 5814, the sale of advertising services is now a retail sale, which means providers collect retail sales tax from clients and pay retailing Business and Occupation (B&O) tax at 0.471 percent on gross receipts instead of the old Service and Other Activities rate.¹ The B&O rate dropped, but adding sales tax to the invoice raises the total tax on the transaction. Several categories of promotional work are carved out and still follow the older rules.

What Changed on October 1, 2025

Before the change, advertising agencies reported income under Service and Other Activities B&O (1.5 percent for most businesses, higher for larger ones) and did not charge sales tax on creative or strategic work. After October 1, 2025, two things happen on every covered advertising invoice. The provider owes retailing B&O at 0.471 percent of gross receipts.² The provider also collects retail sales tax from the client and remits it to the Department of Revenue, at the rate for the location where the client receives the service under the sourcing hierarchy in RCW 82.32.730.

If you reported advertising income under Service and Other Activities for periods starting October 1, 2025 or later, you need to reclassify it.

Which Services Are Covered

RCW 82.04.050 defines advertising services broadly. The definition includes layout, art direction, graphic design, production supervision, placement of ads, consulting on advertising strategy, search engine marketing, lead generation optimization, web campaign planning, buying ad space online, and tracking website traffic to measure campaign results.³ If your work for a Washington client falls into any of those buckets, the retail classification applies.

What Is Carved Out

Several categories are specifically excluded from the new advertising services definition and keep their prior tax treatment:

Web hosting and domain registration, even when bundled into an agency contract.
Newspaper services as defined in RCW 82.04.214.
Printing and publishing services under RCW 82.04.280, which keep their own B&O rate of 0.484 percent.⁴
In-state radio and television broadcasting services.
Out-of-home advertising: billboards, street furniture, transit ads, in-store displays, point-of-sale signage, dynamic or static signage at live events, and naming rights. Direct mail is not treated as out-of-home advertising and is covered by the new rules.³

An agency running a client’s digital campaign while also managing billboard placements has to split the revenue on its tax return. The digital work is retailing; the billboard work is not.

Rates for Promotional Work That Is Not “Advertising Services”

Anything outside the ESSB 5814 definition stays under Service and Other Activities B&O. That covers things like consulting on billboard campaigns, managing radio or TV ad buys for in-state broadcasters, and advising on newspaper placements. The rates in RCW 82.04.290 are tiered on the prior calendar year’s gross income:

Under $1 million: 1.5 percent
$1 million to $4,999,999: 1.75 percent
$5 million or more: 2.1 percent

These tiers include the workforce education investment phased in for larger businesses, and the Department of Revenue uses aggregate taxable income from the prior year, including affiliated businesses, to decide which tier applies.⁵⁶ No retail sales tax applies to these services.

Pass-Through Media Costs

Agencies that buy media placements for clients can sometimes exclude those pass-through amounts from taxable gross income, but the conditions in WAC 458-20-111 are strict. To treat a payment as a deductible advance or reimbursement, you cannot be legally obligated to pay the expense yourself, you must have no ownership interest in the media space you are buying, and you cannot receive any direct or indirect benefit beyond your agency fee.⁷

The deduction works when the client is primarily liable for the media cost and the agency is acting as a payment conduit. If your contract makes you responsible for the buy and you then bill the client with a markup, the Department of Revenue treats the full amount as your gross income subject to B&O. WAC 458-20-218 reinforces that agencies owe B&O on all gross income and commissions, including media payments, unless the amounts qualify as valid advances and reimbursements.⁸ Contract language on the front end decides the tax treatment on the back end.

Tangible Advertising Materials

Physical advertising products were already retail sales in Washington, and ESSB 5814 did not change that. Printed brochures, custom banners, promotional apparel, and similar items are taxable. The agency collects sales tax based on the delivery location, with combined state and local rates that generally run from roughly 7 to 10.5 percent depending on the jurisdiction.⁸ If you buy materials from an out-of-state vendor that does not collect Washington sales tax, you owe use tax at the same rate. Mailers printed out of state but distributed to Washington households are a common example. Separate product charges from service fees on invoices so the sales tax lines are clear.

Out-of-State Agencies and Nexus

An out-of-state agency has to register for Washington taxes once it hits any of three triggers in the current or prior year: more than $100,000 in combined gross receipts sourced to Washington, physical presence in the state, or being organized or commercially based in Washington.⁹ The $100,000 threshold is the one that catches most remote agencies. A California firm managing digital campaigns for Seattle retailers that crosses that line owes B&O and must collect sales tax on covered advertising services delivered to Washington clients.

Revenue is attributed to Washington based on where the client receives the service under RCW 82.32.730, which for most remote transactions defaults to the client’s address in the seller’s records. Track cumulative Washington receipts through the year so registration happens on time. Back taxes still accrue interest if the Department of Revenue finds the obligation later.

Local City B&O Taxes

State tax is not the whole picture. Many Washington cities impose their own B&O taxes with separate rates and thresholds, including Seattle, Tacoma, Bellevue, Everett, and Renton. Seattle’s service rate rose to 0.658 percent for tax year 2026, though businesses with $2 million or less in annual Seattle gross receipts owe nothing under the city’s revised no-tax-due threshold.

The FileLocal portal at filelocal-wa.gov lets businesses register, file, and pay local B&O taxes for multiple participating cities through one system.¹⁰ Participating cities include Auburn, Bellevue, Des Moines, Everett, Kent, Lake Forest Park, Poulsbo, Renton, Seattle, Shoreline, and Tacoma. Each sets its own nexus rules and rate schedules independently from the state, so you may owe local B&O in one city but not another based on where the work is performed or delivered.

Filing, Deadlines, and Penalties

The Department of Revenue assigns each business a filing frequency (monthly, quarterly, or annually) based on estimated annual tax liability.¹¹ Returns are filed through the My DOR portal. If your advertising income is split between retailing (for covered services) and Service and Other Activities (for excluded categories like out-of-home work), each classification goes on its own line. Periods with no activity still require a return; select “Report No Business” rather than skipping the deadline.¹²

Late payment penalties escalate fast. The penalty starts at 9 percent of the amount owed if tax is not paid by the due date, jumps to 19 percent if still unpaid by the end of the following month, and reaches 29 percent after two months past due.¹¹
