You’re finally making sales on Shopify, but now the tax emails are piling up, and you’re not even sure which state wants your money.�

One customer is in California, another in Texas, and suddenly you’re googling terms like “economic nexus” and “sales tax thresholds” at 1 a.m.�

But here’s the good news: you’re not alone, and you’re not expected to become a tax expert overnight.�

If you’re looking for a done-for-you solution to simplify it all, doola’s sales tax compliance services have your back, so you can focus on selling, not spreadsheets.

We make Shopify US taxes easy for the sellers by handling registrations, automated filings, tracking deadlines, and providing expert support built right into our dashboard.

We’ve also created this guide, a Shopify-specific, e-commerce-focused breakdown of how US sales tax works, what it means for your store, and what steps you need to take to stay compliant without sacrificing growth.

So, let’s dive right in.

Why US Sales Tax Matters for Shopify Sellers

There are over 11,000 tax jurisdictions in the United States. That means sales tax rules can vary not just by state, but also by county, city, and even district.�

It’s one of the most decentralized and complex tax systems, which makes it nearly impossible to apply a one-size-fits-all approach. You might be compliant in one state but non-compliant in another, and not even know it.

Here’s where it gets even trickier: Shopify sellers can unknowingly trigger tax obligations just by making a handful of sales in the “wrong” state.�

Most states now enforce economic nexus laws, which require sales tax collection and remittance if a business surpasses a certain revenue or transaction threshold, sometimes as low as $100,000 or just 200 orders per year in a single state.

The result? You might hit an invisible tax threshold in a state you’ve never even visited, simply because your store is doing well.�

For example, if your product gains traction with customers in New York, Texas, or California, you could suddenly find yourself with tax responsibilities there, even if you’re not based there.

That’s why understanding US sales tax is critical for Shopify sellers scaling nationally or internationally.�

Knowing where you owe tax (and when) can make the difference between sustainable scaling and an administrative nightmare.

Understanding Nexus for Shopify US Taxes: Physical vs. Economic Presence

Nexus simply means a connection or presence that creates a legal obligation for you to collect and remit sales tax in a specific state.�

There are 2 main types of nexus: physical and economic, and many sellers don’t realize how easily one or both can be triggered.

Key Triggers for Physical Nexus

This applies when your business has a tangible connection to a state. Shopify sellers can trigger physical nexus through:

• Inventory storage: Using a 3PL or warehouse (e.g., Amazon FBA or a fulfillment partner in New Jersey).

• Employees or contractors: Having remote staff, customer service reps, or salespeople in another state.

• Trade shows or pop-ups: Even temporarily selling in-person at a market or event can establish a physical nexus.

Example: A Shopify store selling eco-friendly skincare uses a fulfillment center in New Jersey to ship orders faster. Even though the owner is based in the UK, storing inventory there creates a physical nexus and triggers tax obligations in NJ.

Key Triggers for Economic Nexus

This is where most Shopify sellers get caught off guard. Economic nexus is triggered when your sales in a particular state exceed a certain revenue or transaction threshold, usually:

• $100,000 in annual sales, or

• 200 separate transactions in a calendar year(Thresholds vary by state; some are higher, others don’t count transactions.)

Example: A California-based Shopify store goes viral on TikTok, generating $120,000 in sales from customers in Texas. Without ever having a physical presence there, they’ve triggered an economic nexus in Texas and now need to register and collect sales tax.

These thresholds are often invisible to sellers. There is no warning email or Shopify pop-up when you cross the line. That’s why so many entrepreneurs are caught off guard, especially when their store suddenly scales.

With our sales tax guide, you’ve taken the first step toward staying compliant and avoiding penalties.�

How Shopify Handles Sales Tax Settings

Shopify does a great job of making things easy for sellers, but ease can be misleading when it comes to sales tax.�

While Shopify can help you collect sales tax, it won’t manage your compliance, register you in states, or file returns.

In reality, Shopify’s tax tools are just the starting point. Understanding what’s automated and what’s not is key to staying compliant.

Tax Collection Methods via Shopify

Here’s what Shopify does when it comes to US sales tax:

✔️ Auto-calculates sales tax rates by region: Based on the customer’s location, Shopify calculates the appropriate state, county, and city tax rates (pulled from tax databases).

✔️ Collects tax at checkout (if enabled): If you’ve added tax regions in your admin settings and you’re registered in a state, Shopify will charge customers the correct rate.

✔️ Set tax overrides and exemptions: You can manually adjust rules for specific products or regions (applicable for states with quirks like tax-free clothing or food).

✔️ Integrates with some third-party tax apps: Most (if not all) tax tools can sync with Shopify to enhance tax calculations or filing, but these still require manual setup and management.

However, here’s what Shopify doesnot do:

❌ It does NOT register you for a sales tax permit. You’ll need to do that separately for each state where you have nexus.

❌ It does NOT file your tax returns. You’re responsible for submitting returns and remitting the collected taxes to each state.

❌ It does NOT track where you’ve triggered Nexus. You’ll need to monitor your sales activity to know when you’re obligated to register in a new state.

doola’s Tip for the Do’ers:

Setting up Shopify tax collection is not the same as being compliant. Remember, you might still face penalties if you collect tax without being properly registered or do not collect when you should be.

Quick Setup Guide for Tax Regions in Shopify Admin

To collect tax properly, here’s what you need to do inside Shopify:

• Go to Settings > Taxes and Duties.

• Add the regions where you’re registered. (Shopify only lets you collect in states where you’ve confirmed you’re registered.)

• Enable automatic tax calculations.

• Set product-specific tax overrides, if applicable.

For International Sellers

If you’re based outside the US but sell to American customers, the same nexus rules apply.�

You may still need to register for US sales tax in certain states, especially if you store inventory there (e.g., via a 3PL) or exceed economic thresholds.

Shopify is a powerful platform, but when it comes to compliance, you need more than toggles and checkboxes.�

That’s where doola can help, with automated tracking, registration, and filing, tailored for Shopify sellers.

State-by-State Breakdown: What Varies and Why It Matters

When it comes to sales tax, no two states play by the same rules.�

In California, for example, once your sales hit $500,000 annually, you’re required to collect and remit sales tax, regardless of transaction count. But that’s just the beginning.�

California’s layered tax structure includes not just state-level rates but also county and district-level taxes, which can vary dramatically even within the same ZIP code.�

New York is equally challenging. Clothing under $110 is tax-exempt at the state level, but some counties can still charge local tax.�

Texas might seem simpler at first. However, that simplicity disappears if you have a physical presence, like storing inventory in a Dallas fulfillment center or hiring a local contractor.�

In Florida, even if you didn’t collect any sales tax in a given month, you’re still expected to submit a return if your business is registered.�
