Seattle Tax Jurisdiction Breakdown for 2024

• Other Local Sales Tax: 3.85%

What is the sales tax rate in Seattle, Washington?

The minimum combined 2024 sales tax rate for Seattle, Washington, is 10.35%. This is the total of state, county, and city sales tax rates. The Washington sales tax rate is currently 6.5%. Other local sales taxes in Seattle are an additional 3.85%.

These other local taxes are not “city sales taxes” exactly, but they fund public projects in the Seattle area, such as:

• Sound Transit Sales and Use Tax: Part of the local sales tax goes toward funding Sound Transit, the regional transit authority, for expanding and maintaining light rail, bus rapid transit, commuter rail, and other transit services.
• Housing and Education Levies: Seattle voters have approved several levies over the years to fund affordable housing projects and educational programs. While not directly a sales tax, they illustrate the types of initiatives that local taxes support.

These rates go for standard taxable products. But other rates might apply to your business.

If you’re selling “vice” products like tobacco or alcohol, you might have an increased rate. If you’re selling essential items, such as medicine or clothing, or educational materials, you might have an exempt or reduced rate. More on that next!

What products are exempt from Seattle sales tax rate?

What digital products are taxed in Seattle?

First, let’s confirm what you’re trying to sell in Seattle. Are you selling digital products?

A digital product is any product that’s stored, delivered, and used in an electronic format. These are goods or services that the customer receives via email, by downloading them from the Internet, or through logging into a website.

You’re probably consuming and using digital products all day long, whether or not you realize it. Here are some common ones on the market today:

• E-books, images, movies, and videos, whether buying a copy from Shopify or using a service like Netflix. In tax language, these products are in a category usually called, “Audio, visual, or audio-visual products.”
• Downloadable and streaming music, whether buying an MP3 or using a service like SoundCloud or Spotify. Of course, these products also fall in the audio category.
• Cloud-based software and as-a-Service products, such as Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS).
• Websites, site hosting services, and internet service providers.
• Online ads and affiliate marketing. Income from these services can be considered taxable under digital tax policies.

These digital products are considered tangible personal property for tax purposes, and the standard state tax rate of 6.25% applies.

What creates sales tax nexus in Seattle?

Since Seattle is located in Washington, it follows the same state-level sales tax nexus rules.

Forms of Washington state sales tax nexus include:

• Economic nexus: When a business sells goods worth $100,000 in the state within the previous or current tax year. More on that below!
• Physical location: This could be an office or a warehouse holding your inventory.
• Employee location: If you have an employee or any other type of representation based in a particular state or city, your business must register for sales tax there.
• Affiliate nexus: If you rely on in-state businesses to promote and refer your business, and you receive a substantial amount of income through these affiliates, then you have sales tax nexus.
• Trade Shows: Even if you don’t have real estate in a place, if you visit trade shows or markets for more than 15 days in the calendar year, that’s enough of a physical present to constitute sales tax nexus in Washington.

Seattle economic nexus as a remote seller

If your business is fully located outside of Washington, then economic nexus is your main concern. Here’s how it works.

The economic threshold amount refers to your total sales in the whole state, during any 12-month period. This can be a calculation of sales in the last twelve months, or a prediction of sales in the next twelve months — any rolling year-long period, past or future.

Basically, if your annual sales in Washington remain below $100,000, then you don’t need to worry about sales tax at all. Phew!

But once your sales do surpass $100,000, then you must register for sales tax and comply with all of the Washington rules around tax rate and collection, invoices, and filing returns.

Who needs a seller’s permit in Seattle?

Any business with sales tax nexus, according to the rules above, must apply for a seller’s permit in Washington right away.

The seller’s permit comes with a sales tax registration number, which establishes you in the Washington tax system as a legal business. This number tracks your business through the system: the taxes you pay, the tax credits you receive, plus the tax you charge from customers.

So, it turns out you do need to register for tax in Seattle. Don’t worry! Just follow these instructions on how to register for sales tax in Washington and that will cover you across the state.

How to calculate Seattle sales tax?

Once you’re registered for taxes, you’re expected to apply sales tax to every taxable sale to a Seattle resident. That means 10.35% for most products.

If your customer is a fellow business, and they’ve provided a valid sales tax exemption certificate, then adding and collecting tax isn’t necessary.

Tax-compliant receipts in Seattle

In order to comply with tax laws, you should include the following information on your receipts or invoices to customers in Seattle:

• Your business’ name and address
• Your business’ sales tax registration number
• Invoice date
• Invoice sequencing number
• Buyer’s name and address
• Buyer’s sales tax registration number, if they have one.
• sales tax (amount and rate) applied to each item

The easiest solution for the sales tax receipt would be to use a sales tax software that automatically generates and sends all invoices (as soon as the sale is complete), and also stores them in the cloud for you.

How to file and pay sales tax in Seattle

Charging and collecting tax is only the first half of staying compliant. The second half is filing returns and paying whatever you might owe to the government.

Washington businesses must file sales tax returns based on their volume of sales:

• Businesses with high sales volumes file monthly.
• Smaller businesses may file quarterly or annually.

Washington sales tax returns are due on the 25th day of the month following the reporting period. If the due date falls on a weekend or holiday, filings are due the next business day.
