Washington Sales Tax on Services (2026): Penalty Relief Now, Repeal in 2029
Updated July 2026
Washington’s 6.5% state sales tax now applies to certain services under ESSB 5814, which took effect in October 2025. A repeal is coming January 1, 2029, advertising services stay taxable even after that, and the Department of Revenue (DOR) is offering penalty relief for businesses that fell behind while the rules were unclear. If you run a service business in Washington, that’s the short version.
The longer version has a few moving parts, so we’ve laid them out in plain language below. We’re Lewis Group CPAs, and we advise service businesses across Southwest Washington on exactly these questions. If you want us to sort your situation directly, reach out to our team or call (360) 896-8221.
What Is the Washington Sales Tax Rate?
The Washington state sales tax rate is 6.5%. Local rates add on top of that, and in some areas the combined total pushes past 10%. Washington is a destination-based state, so you charge the rate where your customer receives the goods or service, not where your office sits.
Because rates vary by address, use the DOR’s tax rate lookup tool to get the exact combined rate for a given location. It’s the same tool the state points businesses to, and it takes the guesswork out of billing.
A quick note on use tax, since it often rides alongside sales tax questions: if you buy something for your business and no Washington sales tax was collected at the point of sale (say, from an out-of-state vendor), you may owe use tax at the same rate. It’s the state’s way of keeping in-state and out-of-state purchases on equal footing.
The Big News: A Repeal Is Coming in 2029
The headline change is ESSB 6346, which repeals the sales tax on many services effective January 1, 2029. That’s real relief, but read the date carefully. The tax does not disappear tomorrow. Between now and the end of 2028, the newly taxable services stay taxable, and you still have to collect, file, and remit like normal.
One exception matters: advertising services stay taxable even after the 2029 repeal. So if your business sells advertising, including digital ads, don’t plan around a full sunset. That category is carved out and stays on the taxable list.
Why does a three-year runway matter for you? It gives you time to plan. You can adjust invoicing systems now, budget for the tax through 2028, and set a reminder to revisit your pricing and processes as the 2029 date approaches. We’d rather you make those changes calmly than scramble later.
Which Services Became Taxable in 2025?
For a quick refresher, the 2025 expansion under ESSB 5814 pulled a range of previously exempt services into the definition of a “retail sale,” which means sales tax applies. The most common categories:
- Advertising services, especially digital ads (and again, these stay taxable past 2029)
- Information technology (IT) services, including tech support and data processing
- Custom website development and software customization
- Live presentations such as webinars, workshops, and training courses
- Investigation and security services
- Temporary staffing services
If your business touches any of these, the rules apply through 2028. Traditional professional services like accounting, legal, and engineering were not made automatically taxable, though the removal of the older “digital automated services” exemption created real gray areas. That’s what the next section addresses.
How SB 6113 Clears Up the Gray Areas (Retroactively)
The confusing part of the 2025 law was how it treated services delivered electronically. If you emailed a client a report or delivered work through software, was that suddenly a taxable digital service? A lot of business owners lost sleep over that question, and honestly, so did a lot of tax pros.
SB 6113 provides clarifications, and it does so retroactively. The clarified treatment reaches back to when the original rules took effect rather than starting fresh. That matters if you made a reasonable classification call last fall and want to know you weren’t quietly building a liability.
Because these rules apply backward in time, this is a good moment to review how you classified your services since October 2025. If you treated something as taxable that the clarification now exempts, you may have collected tax you didn’t need to, which affects both your customers and your filings. If you treated something as exempt that turned out to be taxable, the penalty-relief program below is your friend.
Do Out-of-State and Remote Sellers Owe Washington Sales Tax?
Possibly, and this is where we see one of the most common mistakes right now. Out-of-state businesses selling now-taxable services (IT, custom development, advertising) to Washington customers can have a Washington obligation. But many of them are paying tax without checking whether they actually fall below the state’s minimum thresholds for an obligation in the first place.
If you’re an out-of-state seller, the answer is worth confirming before you keep remitting. We work with clients in both Oregon and Washington, so this is squarely something we handle.
The DOR Penalty-Relief Program
Here’s the part that helps if you’ve fallen behind. The Department of Revenue is running a penalty-relief program tied to these law changes. The idea is straightforward: if you were trying to comply with genuinely unclear rules and got it wrong, DOR wants to give you a path to fix it without piling on penalties.
Penalty relief is not the same as forgiving the tax itself. You’ll generally still owe the underlying sales tax you should have collected and remitted, plus potentially interest. What relief can reduce or waive is the penalty layer, which is often the most painful surprise on a late or corrected return.
If you know you have gaps in your 2025 or 2026 filings, this program is worth acting on. The sooner you correct the record, the cleaner the outcome. We’ve helped a handful of clients navigate these issues already.
What Service Businesses Should Do Right Now
You don’t have to overhaul everything, but a few concrete steps will keep you in good shape through the repeal date.
Review your classifications since October 2025
Pull your invoices and check which services you charged tax on and which you didn’t. With SB 6113’s retroactive clarifications in play, some of those calls may need adjusting in either direction.
Keep collecting correctly through 2028
Charge the rate where your customer receives the service. For a service sale, that generally means the location where the customer receives the benefit of the work, not your office address. Use the DOR rate lookup to confirm the address-based rate and keep your records tidy.
Use the penalty-relief program if you’re behind
If you missed collecting or remitting during the confusion, don’t wait for a notice. Addressing it proactively through the relief program almost always beats being found later.
Mark your calendar for 2029
Set a reminder to revisit pricing, contracts, and invoicing systems ahead of the January 1, 2029 repeal, and remember advertising stays taxable.

Frequently Asked Questions
What is Washington’s sales tax rate in 2026?
Washington’s state sales tax rate is 6.5%, and local rates add on top so that combined totals exceed 10% in some areas. Because the state is destination-based, you charge the rate for the location where your customer receives the goods or service.
Are services subject to sales tax in Washington?
Yes, certain services are taxable through the end of 2028 under ESSB 5814, including advertising, IT services, custom software and website development, live presentations, investigation and security services, and temporary staffing. Traditional professional services such as accounting, legal, and engineering were not made automatically taxable.
When is the Washington sales tax on services being repealed?
The sales tax on many services is repealed effective January 1, 2029, under ESSB 6346. Until then, the affected services stay taxable and you must continue to collect, file, and remit.
Which services stay taxable after the 2029 repeal?
Advertising services, including digital ads, remain taxable even after the 2029 repeal. That category is specifically carved out of the sunset.
Do I owe sales tax if I delivered a service electronically?
Not automatically. SB 6113 clarified how electronically delivered services are treated, and it applies retroactively to when the 2025 rules took effect, so a service you delivered by email or software is not taxable simply because of how it was delivered. Reviewing your past classifications is the way to be sure.
Who qualifies for the DOR penalty-relief program?
The DOR penalty-relief program is aimed at businesses that tried to comply with genuinely unclear rules and got it wrong. It can reduce or waive penalties on late or corrected returns, though you’ll generally still owe the underlying tax and any interest.
