Shopify tax and duties setup: the basics before you sell

Tax setup is unglamorous and unforgiving of guesses. The registrations, product taxability, and duties decisions a new Shopify store should settle before the first international or out of state order.

What Shopify does and does not decide for you

Shopify calculates and collects tax at checkout based on the settings and registrations you provide. It does not decide where you owe tax. That obligation, called nexus, comes from where your business has presence or sufficient sales, and it is a legal and accounting determination no platform setting can make for you.

This distinction matters because a store can be perfectly configured and still non compliant, collecting in the wrong places or failing to collect where a registration was needed. Treat the platform as the calculator and your accountant as the map. Set up the calculator only after you know the map, or be ready to revisit settings as the map clarifies.

Registrations and rates, the setup order

Start where your business is physically based, since that registration is almost always required once you sell taxable goods. Then review where your sales volume is growing, because economic thresholds in other states can create obligations as you scale. Register before you cross, not after a notice arrives, where your advisor flags likely exposure.

Inside Shopify, enter the registrations you actually hold so collection matches them, confirm your product categories are set correctly, since taxability varies by product type and place, and check whether your prices are set as tax inclusive or exclusive. That last toggle quietly changes displayed prices and margins, and stores discover it wrong at the worst moments.

Duties for international orders

Duties are a separate layer from domestic tax. When you sell across borders, someone pays import duties and taxes, and the only question is whether it is priced transparently at checkout or demanded from your customer at the door. The door option generates refused deliveries, chargebacks, and support tickets out of all proportion to the order value.

Decide per market how duties are handled, delivered duties paid at checkout where your setup supports it, or clearly messaged expectations where it does not. Record the decision in your shipping and returns pages in plain language. Surprises are the problem, not the existence of the charge itself.

Records, filings, and the quarterly habit

Collecting tax creates a filing rhythm. Know who files, how often, and from what report, before the first deadline exists. Shopify reporting can feed those filings, and many stores add a tax service as volume grows, but the responsibility stays yours even when the arithmetic is outsourced.

Build a quarterly review into the calendar. Sales by state, new registrations needed, product line changes that alter taxability, and any marketplace sales that follow different rules. Tax setup is not a launch task you finish. It is a small recurring obligation that stays cheap only while it stays current.

Frequently asked questions

Does Shopify automatically handle sales tax for me?

Shopify calculates and collects based on your settings and registrations, and can help with reporting, but it does not determine where you have obligations or register you anywhere. Those decisions need your accountant input, especially as sales spread across states.

When do I need to collect tax in another state?

Generally when you have physical presence there or your sales cross that state economic threshold. Thresholds and rules vary, and they change, which is why growing stores review sales by state regularly with an advisor rather than relying on launch day assumptions.

Should I show prices with tax included?

It depends on your market norms. Tax inclusive pricing is standard in many countries and confusing in much of the US, where shoppers expect tax added at checkout. Pick the convention your customers expect, set it deliberately in Shopify, and check the storefront display matches.

Who pays duties on international orders?

Either your customer at delivery or your business through duties collected at checkout, depending on your setup. Checkout collection is far better for customer experience where available. What matters most is that the arrangement is decided and clearly communicated before ordering.
