Do I need to collect sales tax on dropshipping in the US?

Nexus is the whole question

There is no federal sales tax and no single answer. You collect where you have nexus — a connection to a state strong enough that it can require you to collect — and the rest of this page is about when that connection exists.

Two kinds matter for a dropshipping store.

Physical nexus: your home state, from order one

If you live and operate in a state with sales tax, you have nexus there immediately. No threshold, no grace period, no first hundred orders.

That is the obligation people miss, because it arrives before there is any revenue to notice it with. Register for a permit in your own state before your first campaign, not after your first good month.

Economic nexus: the thresholds

Since 2018, states can require remote sellers to collect once sales into that state pass a threshold. The common baseline is $100,000 of sales into that state in a year. Several states add a 200-transaction test, though that test is steadily being repealed. The large states set the bar higher: California and Texas at $500,000, New York at $500,000 and 100 transactions.

Two practical consequences:

• A small store is almost never over the line outside its home state. $100,000 into one state is a large business. Do not register in 45 states because a Facebook group told you to.
• The transaction test is the one that catches you. A store selling a $29 product into a state with a 200-order threshold hits it at $5,800 of revenue, not $100,000.

What dropshipping adds: the resale certificate

Your customer sale is one transaction. Your purchase from the supplier is another, and a US-based supplier can charge you sales tax on it unless you hand over a resale certificate showing the goods are for resale.

This does not apply to suppliers shipping from China. It matters the moment you move to a US wholesaler for faster domestic shipping, which is exactly when nobody is thinking about paperwork.

The practical setup

1. Register in your home state before launch.
2. Switch on tax collection in your platform for that state only.
3. Track sales per state monthly. Shopify reports this without an app.
4. Register in a new state when you approach its threshold, and switch collection on there too.
5. File on the schedule the state gives you, including zero returns in quiet months.

Shopify calculates and collects. It does not register or file. Treat those as your job or your accountant’s.

Sales tax is not income tax

They get conflated constantly, and they behave in opposite ways.

Sales tax is your customer’s money. You collect it on top of the price, hold it, and pass it to the state. It is never revenue and it should never sit in your operating balance.

Income tax is on your profit, filed where your business is registered, and has nothing to do with which state your customer lives in.

A store can owe sales tax in five states and income tax in none, in a year it lost money. Treat them as two separate obligations with two separate calendars.

What getting it wrong costs

Uncollected tax remains your liability, with interest and penalties, and it compounds monthly. It is also the kind of problem that surfaces during a sale or an audit years later, when the amounts have grown and the records have not.

The fix is cheap and early: one 30-minute conversation with an accountant in your country before your first $1,000 of revenue. Ask when you must register, when you must collect, and what records to keep from day one. That conversation costs less than one failed product test — the same argument as do I need an LLC, and for the same reason.

Selling into Europe instead? The rules are stricter and the thresholds are lower — EU dropshipping VAT covers IOSS and the EUR 150 rule. The full pre-launch sequence, tax step included, is on the 10-step launch roadmap.
