Running a business on Shopify is exciting—but figuring out sales tax and how to set it up? Not so much. It’s one of those things that often gets pushed to the bottom of the to-do list until it suddenly becomes a problem. The good news? Getting it right from the beginning can save you time, money, and a ton of stress, allowing you to enjoy your Shopify business. So let’s walk through what you need to know about sales tax as a Shopify seller—without the jargon.
Should You Use Shopify Tax?
Shopify has its own tax calculation tool called Shopify Tax. If you’re new to ecommerce, you might be wondering if it’s necessary. Here’s the lowdown:
- Shopify Tax is free for your first $100,000 in annual sales.
- After that, they charge 0.35% per transaction, capped at $5,000 annually.
- Shopify Tax automates sales tax calculation, making life easier if you’re selling in more than one state.
However, it doesn’t cover everything. Shopify Tax doesn’t handle registration, filing, or remitting tax payments. It’s a helpful tool, but not a full solution.
Many sellers assume Shopify handles the whole sales tax process just because tax is showing up on their Shopify checkout screen. But that’s not the case. It’s your responsibility to ensure you’re compliant from start to finish.
Step 1: Determine Where You Have Nexus
“Nexus” is the legal term for a connection to a state that requires you to collect sales tax there. There are two key types:
- Physical Nexus: This applies if you have a physical presence in a state—like a warehouse, storefront, employee, or even storing inventory through a fulfillment center.
- Economic Nexus: This kicks in when your sales revenue or number of transactions in a state exceeds that state’s threshold, even if you don’t have a physical presence there.
Most states set the economic nexus threshold at $100,000 in sales or 200 transactions in a calendar year. However, some states only use the sales dollar amount, and these rules do evolve, so always double-check the current thresholds.
Nexus can sneak up on you if your Shopify tax isn’t set up properly. You might think you’re safe because you only make a handful of sales in a state, but once your overall volume grows, those thresholds become easier to exceed.
Step 2: Register Before You Collect
Once you know where you have nexus, the next step is registration. Here’s a critical rule: You must register with a state before collecting sales tax there. Collecting, even on Shopify, without a permit is not just risky—it’s illegal.
Registering is usually done through a state’s Department of Revenue website. Some states approve applications quickly, while others may take a few weeks.
If you’re registering in multiple states, be prepared to keep detailed records. Each state has its own login portal, account number, and set of filing dates. Staying organized is key.
Tip: Keep your usernames, login details, and assigned state account numbers somewhere secure—you’ll need them when it comes time to file.
Step 3: Understand Product Taxability
Just because you sell something on Shopify doesn’t mean it’s always taxable. Different states treat products differently. A few examples:
- In New Jersey, most clothing is tax-exempt.
- In Texas, grocery items and medical devices may be exempt.
- Some states have sales and other taxes on digital goods (like e-books or online courses), while others don’t.
Shopify Tax helps categorize products, but you still need to ensure those categories are set up correctly. Incorrect categorization could mean collecting too much—or too little—tax.
It’s a good idea to maintain a list of your products and their tax treatment in each nexus state. This can help avoid overcharges, customer complaints, and unnecessary refunds.
Misunderstanding product taxability is one of the most common sources of errors we see. For example, a Shopify seller offering bundles of physical and digital goods might need to break out pricing to determine the proper tax rate.
Step 4: Collect, File, and Remit
Collecting sales tax on Shopify is only the beginning. You also need to file sales tax returns and remit the funds to each state. Filing frequency is determined by each state and can be:
- Monthly (if you have high sales volume)
- Quarterly (common for mid-sized sellers)
- Annually (for smaller volume)
Some important notes:
- Shopify does not file sales tax for you.
- Many states require zero-dollar returns, even if you didn’t make any taxable sales during that filing period.

Keeping track of due dates is essential. States will not remind you. Missed filings—even with no tax due—can result in penalties, revoked permits, or even forced closure of your tax accounts.
Selling on Multiple Platforms?
Your sales tax obligations don’t stop at Shopify. If you sell on other platforms—like Etsy, Amazon, or eBay—you need to consider your total sales across all platforms when setting up and evaluating economic nexus.
For example:
- $60,000 on Shopify
- $40,000 on Etsy
- $10,000 on eBay
That’s $110,000 total—meaning you may have economic nexus in several states. Unfortunately, each platform doesn’t coordinate your obligations, so it’s up to you to monitor your overall sales footprint.
Also consider whether any of your platforms are marketplace facilitators. Amazon and Etsy collect and remit tax on your behalf in certain states—but not all. You still might have filing requirements even if the tax was already collected. This gets tricky fast, and is another reason to work with someone who understands the full picture.
Real-Life Sales Tax Catastrophes: What Can Go Wrong for Shopify Sellers?
If you’re tempted to ignore sales tax, here are a few stories that might make you think twice:
- A Shopify seller made great revenue but never registered in California. The state eventually caught up, and the audit came to over $250,000. They had to hire a tax attorney and nearly lost their business.
- Another Shopify seller collected tax from customers in five states—but never filed. The state saw this as collecting illegally and demanded back taxes, penalties, and interest.
- A client combined Etsy and Shopify sales but didn’t realize it pushed them over the nexus threshold. They ended up with unexpected obligations in six states, along with late registration fines.
These aren’t outliers—we see cases like these regularly. Most of them were preventable.
One more example: a Shopify seller was auto-collecting tax using a platform default setting, but didn’t realize they had to actually file and remit those funds. The state eventually contacted them, and they had to pay over a year’s worth of taxes they had already collected—but hadn’t sent in. It’s an easy trap to fall into.
What’s the Worst That Can Happen When Tax Issues Go Unchecked?
Here’s the honest truth:
- Collecting without registration = illegal
- Missing filings = penalties and interest
- Willful neglect = potential audits and significant legal exposure
But don’t panic. Most states would rather see you voluntarily come into compliance than chase you down. There are even programs called voluntary disclosure agreements (VDAs) that can help limit your liability if you’re behind.
In most cases, acting quickly and proactively can keep fines low and protect your business reputation. If you know you’re behind, don’t ignore it—reach out for help.
The key is: Don’t wait until a notice shows up in the mail.
States can find out that you should have registered for sales and use tax in many different ways. They can get information directly from Shopify or another platform, get the information from payment processors, or even get the information from another state if one has already audited you. They are getting faster and more sophisticated at catching businesses; it’s not worth the risk!
