Sales Tax & Tariffs: What You Need to Know
All posts
When tariff policies shift, the ripple effects travel fast. For importers, manufacturers, and retailers, these changes go beyond cost. They can upend compliance responsibilities, reshape pricing models, and leave sales tax strategies dangerously outdated.
Tariffs impact your sales tax obligations more than you might think.
In this guide, we’ll unpack how tariffs intersect with sales tax compliance and provide actionable steps to help your business stay protected and proactive, even in a volatile trade environment.
Tariffs are taxes imposed on imported goods. When they increase, your cost of goods sold (COGS) rises. Businesses often respond by raising prices, adjusting sourcing strategies, or using new logistics providers. Each of those moves can have unintended (and often unnoticed) consequences on your sales tax exposure.
Whether a tariff surcharge is taxable depends on who pays it and how it appears on the invoice.
The key distinction is whether your business is the importer of record or if you’re passing the tariff cost to your customer.
Example: You sell a product for $10,000 and add a $500 “Tariff Fee” to the invoice. In some states, you’ll need to charge sales tax on $10,500, not just the product price.
When in doubt, get guidance. Whether you’re importing goods or invoicing customers, how you handle tariffs can directly affect your compliance.
When businesses adjust to tariffs, they often unknowingly cross new nexus thresholds. Nexus is the connection between your business and a state that creates a sales tax obligation.
One common example is shifting how and where you store products. To reduce costs tied to international tariffs, you might begin using third-party logistics providers (3PLs) or establish warehousing within the U.S. While these moves can improve fulfillment and reduce shipping times, they often create physical nexus—and with it, new tax responsibilities.
Let’s look at the state of Washington to illustrate this. According to the Washington Department of Revenue, maintaining inventory in the state (even if held by a third party like a 3PL) creates physical presence nexus. That means you may need to register, collect, and remit sales tax in that state, even if your business has no other activity there.
Example: You used to ship all your products from Texas. To streamline delivery, you now store inventory with a 3PL in Ohio. That inventory creates a physical presence in Ohio, requiring you to comply with that state’s sales tax laws.
It’s not just logistics. If your new supply chain setup or pricing strategy increases your sales volume, you could also cross economic nexus thresholds. These thresholds—such as $100,000 in sales or 200 transactions annually—vary by state but trigger the same sales tax obligations.
When tariffs force you to rethink what or how you sell, they can directly impact taxability. States don’t all tax products the same way, and even small adjustments can change your obligations.
Example 1: You used to sell a bundled electronics kit, but due to tariff hikes on one of the components, you now sell the items separately. Depending on the state, bundled vs. unbundled transactions are taxed differently. You may owe sales tax where you previously didn’t.
Example 2: You swap a tax-exempt imported item for a domestic version with different specifications. In your state, the new version is taxable. Suddenly, your exemption no longer applies, and your customers need to start paying tax on it.
These small shifts often fly under the radar until an auditor points them out. That’s why businesses should review product taxability every time they adapt their supply chain or SKU structure.
Failing to connect tariff decisions with your sales tax strategy can lead to the following:
Over time, these issues can snowball into financial penalties, revoked licenses, or reputational damage.
