The Critical Shopify-vs-Amazon Difference
Shopify is NOT a marketplace facilitator for direct merchant stores. This is the single most important fact for any cross-border ecommerce seller to understand.
When you sell on your own Shopify store at yourbrand.com, you are the seller of record on every transaction. Sales tax collection, remittance, registration, filing — all your responsibility, in every state where you have nexus.
This is fundamentally different from Amazon FBA, where Amazon collects and remits sales tax under marketplace facilitator laws. With Shopify direct, there is no marketplace platform doing the collection for you.
The exception: Shop App orders (orders placed through the Shop mobile app, not your own domain). Since 2025, Shopify acts as a marketplace facilitator for Shop App orders only and collects/remits tax on those. But Shop App is a small fraction of typical merchant volume.
Practical implication: A cross-border seller with $500,000 in U.S. Shopify direct sales has registration and filing obligations in every U.S. state where they exceed the economic nexus threshold (usually $100,000) — that’s typically 5–15 states minimum. Add Amazon FBA on top, and the combined footprint can be 25–40+ states.
How Shopify Direct Sellers Determine Sales Tax Nexus
Two types of nexus apply to Shopify merchants:
Economic Nexus (sales-volume-based)
Triggered when your Shopify direct sales into a state exceed that state’s threshold:
- $100,000 in most states (MA, MI, MD, NC, VA, WA, etc.)
- $500,000 in CA, TX, NY (NY also requires 100+ transactions)
- $250,000 in AL and MS
- $100,000 OR 200 transactions in AZ, CT, GA, HI, IL, KY, MD, MI, MN, NE, NJ, NV, OH, OK, RI, VA, WV (and more)
- None in AK (state-level), DE, MT, NH, OR (no general sales tax)
Physical Nexus (presence-based)
Triggered by physical presence in a state, regardless of revenue:
- Inventory stored in a state (FBA, 3PL, your own warehouse)
- Employees or contractors in a state
- Drop-shipping vendor in a state (in some interpretations)
- Trade shows or temporary retail in a state
Use Shopify’s built-in Tax Insights or Manage Tax Liability report (Settings → Taxes and Duties → Tax Insights) to see your sales by state. Shopify will flag states where you’ve crossed (or are approaching) economic thresholds — but you still have to act on the registration yourself.

The Shopify + Amazon FBA Combination Trap
Most successful cross-border sellers run BOTH Shopify direct and Amazon FBA. The combined nexus footprint is usually much bigger than either channel alone.
Worked example: A South African seller with $600,000 of U.S. revenue split 60% Shopify ($360K) / 40% Amazon FBA ($240K):
- FBA inventory creates physical nexus in 15–25+ states (Amazon distributes inventory automatically across CA, TX, PA, NJ, OH, IL, FL, GA, NC and more)
- Shopify direct $360K aggregates into U.S.-wide sales — typically exceeding the $100K threshold in 4–8 states (CA, TX, NY, FL, IL, OH, GA, PA likely)
- Combined nexus footprint: registration required in ~25–30 states
Of those 25–30 states, Amazon collects + remits sales tax on the FBA portion (marketplace facilitator). On the Shopify portion, the seller collects + remits themselves. Both flows run through ONE state account per state.
Several states (Texas, Ohio, Nevada, New Jersey, Michigan, Hawaii) include marketplace sales when measuring economic nexus thresholds for direct-sale purposes. So even an FBA-only seller can trigger Shopify-style direct registration if their Amazon volume is high.
Configuring Shopify for U.S. Sales Tax Collection
Once you’ve registered in a state, you have to tell Shopify to start collecting tax for that state. The setup is in Settings → Taxes and Duties → United States:
- Click Add region and select the state.
- Enter your state sales tax permit number (the registration certificate number issued by the state DOR).
- Choose between Shopify Tax (auto-calculated, rooftop-accurate, includes clothing/exemption logic) or Manual Tax (you specify the rate).
- Save. Shopify will start collecting at the destination rate on every order to a customer in that state.
Shopify does not file or remit the tax for you. It collects the tax from your customer at checkout — you are responsible for filing returns and remitting the collected tax to each state’s Department of Revenue on the state’s filing schedule (monthly, quarterly or annually depending on your volume).
Shopify Tax (paid feature) vs basic Shopify tax settings
For cross-border sellers selling apparel, food, digital goods or anything with state-specific exemption rules, the basic Shopify tax settings are not enough. Examples where basic settings will OVERCHARGE customers (causing refund requests and audit risk):
- Massachusetts: clothing under $175 is exempt — basic settings tax it at 6.25%
- New York: clothing under $110 is exempt from state 4% (and most local)
- Connecticut: clothing under $50 is fully exempt; over $1,000 is luxury 7.75%
- Pennsylvania, New Jersey, Minnesota, Rhode Island, Vermont: clothing fully exempt year-round
Shopify Tax handles all of these correctly. Basic Shopify tax settings do not. Cost is approximately 0.35% of orders (waived under $100K/year in U.S. tax-collected sales).
Shopify Setup for International Sellers
Shopify accepts foreign business addresses on store registration — your South African Pty Ltd, UK Ltd, German GmbH, Indian Pvt Ltd, etc. can all open a Shopify store with your home-country address. There is no requirement to incorporate in the U.S.
The two practical complications for cross-border sellers:
1. Shopify Payments and U.S. payouts
Shopify Payments (Shopify’s built-in payment processor) requires a U.S. bank account to receive USD payouts in some configurations. For cross-border sellers, the standard workarounds are:
- Stripe Connect (alternative payment processor) with payouts to Wise Business or Mercury — both give you U.S. routing/account numbers without needing a U.S. LLC
- Form a U.S. LLC and use Mercury directly
- Use PayPal as the payment processor (limited but works internationally)
2. ACH-capable banking for state DOR sales tax remittance
Most U.S. state DORs require ACH (electronic debit) for sales tax payments. Same setup as above: Wise Business (no U.S. LLC needed) or Mercury (with U.S. LLC) gives you the U.S. routing/account credentials state DORs accept.
3. Shopify Managed Markets (international VAT/duties)
If you also sell INTO countries outside the U.S. from your Shopify store, Shopify Managed Markets (powered by Global-e) handles international VAT calculation, duty collection at checkout, and customs documentation in 200+ countries. This doesn’t help with U.S. sales tax (which is a separate regime) but is worth enabling for non-U.S. international sales.

Frequently Asked Questions
1. Is Shopify a marketplace facilitator? Why does it not collect sales tax for me like Amazon does?
Shopify is NOT a marketplace facilitator for direct merchant stores. When you sell on yourbrand.com, Shopify just provides the storefront and checkout — you are the seller of record. Sales tax collection is your responsibility (though Shopify can calculate and collect it once you configure it state-by-state in Settings → Taxes and Duties). Amazon, in contrast, IS a marketplace facilitator under state law — Amazon takes the seller-of-record role for tax purposes on FBA sales. Shop App orders are the only Shopify channel where Shopify acts as marketplace facilitator (since 2025).
2. Do I need Shopify Tax (the paid feature) or are basic settings enough?
If you sell apparel, food, digital goods or anything with state-specific exemption rules, you need Shopify Tax. Basic settings will OVERCHARGE in states like Massachusetts (clothing under $175), New York (clothing under $110), Connecticut (multiple thresholds), Pennsylvania/New Jersey/Minnesota/Rhode Island/Vermont (clothing exempt year-round). Shopify Tax handles all of these. Cost ~0.35% of order value (waived under $100K/year).
3. Can I run a Shopify store from outside the U.S. and sell to U.S. customers?
Yes. Shopify accepts foreign business addresses (SA Pty Ltd, UK Ltd, German GmbH, Indian Pvt Ltd, etc.). The two practical complications: (1) U.S. payouts may need Wise Business or Mercury for ACH-capable banking; (2) Sales tax registration in every state where you exceed economic nexus thresholds. We handle both.
4. What's the bare minimum I need to start collecting U.S. sales tax on Shopify?
U.S. EIN (apply by phone with IRS as a foreign entity), Wise Business or Mercury account for ACH-capable banking, sales tax registration in every state where you have nexus (typically 5–15 states for Shopify-only sellers; 20–30 states if you also use Amazon FBA), then configure Shopify Settings → Taxes and Duties with your state registration numbers. Setup takes 4–6 weeks if you do it yourself, or 4–6 weeks with no work on your part if we do it for you.
5. How does Sales Tax Compliance USA bill for Shopify sellers?
Flat monthly fee based on your nexus footprint (number of states), monthly volume and channel mix. A typical cross-border Shopify-only seller registered in 8–12 states pays a fixed monthly fee covering all registrations, filings, remittance and audit support. Add Amazon FBA on top and the fee scales with the larger nexus footprint. We quote a fixed price upfront — no hourly billing, no per-filing charges.
Shopify Sellers Have More Compliance Work Than FBA Sellers
The intuition that ‘Amazon is harder than Shopify because of inventory’ is half right. Amazon FBA does create more physical-nexus states. But Shopify direct sellers carry the seller-of-record responsibility on every checkout — meaning every state where they have economic nexus requires direct collection, filing and remittance.
For cross-border sellers running both channels (the most common pattern), the combined compliance footprint is typically 25–30+ states. Done correctly with the right banking, EIN setup, Shopify Tax configuration and state registrations, this is routine. Done incorrectly, it leads to back-tax assessments, customer refund requests, and Shopify Payments holds.
