Multi-State Sales Tax Nexus for DTC Brands (2026)

Published June 10, 2026 by Invisible LLC Team · 9 min read

You're a DTC operator, not a tax accountant. You started the brand to sell a product people love, and somewhere along the way you became responsible for figuring out whether you owe sales tax in twenty states you've never set foot in. Nobody warned you, and the rules won't sit still.

TL;DR: Since the 2018 Wayfair decision, you can owe sales tax in a state purely based on how much you sell there — no physical presence required. The trigger is called economic nexus, and most states set it at $100,000 in sales or 200 transactions. In 2026 a wave of states, including Illinois, dropped the transaction-count test entirely, which changes the math for low-volume, high-ticket sellers. Here's how to figure out where you've crossed the line, and what to do about it.

What economic nexus actually means

For decades, a state could only make you collect its sales tax if you had a physical presence there — an office, a warehouse, an employee. Then in 2018 the Supreme Court decided South Dakota v. Wayfair, and the rule changed for every online seller in the country.

After Wayfair, a state can require you to collect and remit its sales tax based on economic nexus — meaning you've done enough business in the state to owe, even if you've never physically been there. "Enough business" is defined by a threshold the state sets.

The standard most states landed on, modeled on the South Dakota law the Court upheld, is $100,000 in sales or 200 separate transactions in the state during the current or prior calendar year (Sales Tax Institute, Economic Nexus State Guide). Hit either one, and you have nexus. That "or" is doing a lot of work, and it's the part 2026 is changing.

The 2026 shift: transaction thresholds are disappearing

For a few years, that "$100,000 or 200 transactions" test created a trap for the wrong sellers. A brand doing $40,000 in revenue across 250 small orders could trip the 200-transaction threshold and owe sales tax in a state, even though the dollar volume was tiny. The transaction count caught high-volume, low-ticket sellers the law was never really designed to burden.

States have been quietly fixing this. As of January 1, 2026, 16-plus states have eliminated the 200-transaction threshold, leaving sales-dollar volume as the only test (Avalara, "States eliminating economic nexus transaction thresholds"). Illinois is the most recent and one of the most consequential: effective January 1, 2026, Illinois dropped its 200-transaction count, so remote sellers establish nexus only by exceeding $100,000 in sales into the state (TaxCloud, "Illinois Eliminates Transaction Threshold"; the change came through the state's budget legislation signed June 2025). Illinois joins states like Alaska, Indiana, and Utah that made the same move; Kentucky's transaction threshold goes away August 1, 2026.

Here's the counterintuitive part: for most DTC brands, this is good news. If you were tripping the transaction count in a state without coming close to $100,000 in sales there, you may no longer have nexus once the count goes away. The change cuts the other way only if you'd been relying on a low transaction count to stay under — and that's rare.

The thing to internalize is that nexus rules are not static. They change by statute every year, state by state. A nexus map you built in 2024 is already out of date.

How to figure out where you have nexus right now

You don't need to guess, and you don't need to wait for a letter. Here's the process:

Pull a sales-by-state report. Your Shopify admin can break out sales and order counts by destination state. This is your raw material. If you sell across multiple channels, you need every channel's data, not just Shopify's.
Compare each state's totals to that state's current threshold. For most states the question is now simply: did I exceed $100,000 in sales there in the current or prior calendar year? For the states that still have a transaction count, check both. (The current-or-prior-year window matters — you can establish nexus this year based on last year's volume.)
Flag the states you've crossed, and the states you're approaching. A state where you're at $80,000 and growing is a planning problem you want to see coming, not a surprise next quarter.
Separate marketplace sales from your own. This is the piece that trips people up, so it gets its own section below.

The output of this exercise is a nexus map: the list of states where you're obligated to collect, the states you're nearing, and the states you can safely ignore for now. That map is the foundation of everything else.

The marketplace facilitator wrinkle

If you sell on Amazon, Etsy, Walmart Marketplace, or similar platforms, there's a rule that works in your favor. Under marketplace facilitator laws, now in effect in essentially every state with a sales tax, the marketplace itself is responsible for collecting and remitting sales tax on the sales it facilitates (Sales Tax Institute, Economic Nexus State Guide).

That means your Amazon sales are generally being handled by Amazon, not you. But two things to keep straight:

Your direct (Shopify) sales are still yours. The marketplace only covers what it facilitates. The DTC channel you own is your responsibility.
Marketplace sales may still count toward your nexus threshold in some states, even though the marketplace remits the tax. Whether they do varies by state. This affects whether your own direct sales push you over the line. When in doubt, treat your gross sales into a state as the figure to watch, then sort out who actually remits.

This is exactly the kind of state-by-state nuance where a guess is expensive and a clean answer is cheap.

What to do once you have nexus in a state

Crossing a threshold doesn't mean you're in trouble. It means you have an obligation, and obligations are manageable when you act on them. The sequence:

Register for a sales tax permit in the state. Collecting tax without a permit is itself a problem in most states, so registration comes first.
Turn on collection for that state in Shopify (and any other channel). Shopify Tax and tools like Avalara or TaxJar can automate the rate calculation once you tell them where you're registered.
File and remit on the state's schedule — monthly, quarterly, or annually depending on your volume. Miss the filing and the interest and late charges start, even if you collected the tax correctly.

What you don't want to do is ignore a state where you've clearly crossed the threshold. Uncollected sales tax doesn't go away — it becomes a liability you owe out of your own margin, plus interest, and it surfaces at the worst possible time, often during due diligence when you're trying to raise or sell. Several of the 2026 threshold changes came paired with amnesty windows precisely because so many remote sellers were out of compliance without knowing it.

This is the work we do for DTC brands inside the sales tax and tax compliance service, sitting on top of Shopify-native bookkeeping so the sales data feeding your nexus map is actually clean. The point isn't to bury you in filings — it's to make sure you only register where you have to, collect correctly, and never get surprised by a state you didn't know you'd crossed.

The bottom line

Economic nexus turned every multi-state DTC brand into a multi-state taxpayer, and the rules change every year. The 2026 wave of states dropping transaction-count thresholds — Illinois being the headline — mostly works in your favor, but only if you actually re-run your nexus map against the current rules instead of the rules you memorized two years ago.

The whole thing comes down to three moves: know your sales by state, compare to each state's current threshold, and register where you've crossed. Do that on a regular cadence and the nexus letter never arrives, because you got there first.

Refresh checkpoints

30 days: Confirm the count of states that have eliminated the transaction threshold ("16-plus") is still current; this number is actively growing through 2026.
90 days: Re-verify the Illinois effective date and the $100,000 threshold against tax.illinois.gov; confirm Kentucky's August 1, 2026 change took effect as stated.
180 days: Full re-verification of all state-specific claims — this is a time-sensitive regulatory post. Re-check the Wayfair $100K/200-transaction baseline and marketplace facilitator coverage.
Time-sensitivity note: The state-by-state threshold landscape is the volatile part. The Wayfair framework and the marketplace-facilitator concept are evergreen; the specific state list is not. Treat any state-specific figure as needing re-verification at each checkpoint.
