Since the landmark South Dakota v. Wayfair Supreme Court decision in 2018, every US state with a sales tax has implemented economic nexus rules. Yet, thresholds, filing frequencies, and marketplace facilitator laws vary dramatically by state. Many ecommerce sellers are either over-filing and wasting money, or under-filing and risking audits and back taxes. This article gives sellers a single-source reference to cut through the confusion.
At Branvas, we work with hundreds of ecommerce sellers and new brand founders, and sales tax nexus is consistently one of the first compliance questions they ask when they start shipping product across state lines. Whether you are running a Shopify store, dropshipping, or scaling a multi-channel brand, understanding your exact obligations in 2026 is critical to protecting your margins.
Economic nexus is a legal concept that allows a state to require an out-of-state seller to collect and remit sales tax once the seller reaches a certain level of sales revenue or transaction volume within that state. Unlike the old rules, economic nexus requires absolutely no physical presence (like a warehouse, office, or employee) in the state.
The landscape shifted permanently with the 2018 South Dakota v. Wayfair Supreme Court decision [1]. The Court ruled that the physical presence rule was outdated in the digital age, granting states the authority to tax remote sales based purely on economic activity.
To understand your obligations, it is helpful to distinguish between the different types of nexus:
| Nexus Type | Definition | Trigger Example |
|---|---|---|
| Physical Nexus | A physical connection to a state. | Having an office, warehouse, employee, or inventory stored in the state. |
| Economic Nexus | A financial connection to a state based on sales volume. | Exceeding $100,000 in revenue or 200 transactions in a state. |
| Click-Through Nexus | A connection established through in-state referrals. | Paying a commission to an in-state affiliate for referring sales via a link. |
| Affiliate Nexus | A connection through affiliated entities. | Having an affiliated business operating in the state that helps establish a market. |
Many sellers assume that once they hit a threshold in a state, they owe tax retroactively from dollar one. However, most states only require collection prospectively, going forward from the date the threshold was crossed [2]. For example, if you cross a state's $100,000 threshold in October, you are generally only required to collect tax on sales made after that date, not on the first $100,000.
To simplify compliance, we developed The Branvas Nexus Clarity Framework (NCF). This 4-step decision model is what ecommerce sellers should use before registering for sales tax in any new state.
Example: A Shopify seller generates $85,000 in sales to Texas customers across 210 transactions in 2025. Texas threshold: $500,000 revenue OR 100 transactions. Transaction count is exceeded (210 > 100). The seller must register, but because they sell exclusively through their own Shopify storefront (not a marketplace facilitator), they must collect and remit themselves. Filing frequency at this volume: likely quarterly.
This table provides a comprehensive view of economic nexus thresholds, marketplace facilitator laws, and filing frequencies across all 50 states and Washington D.C. for 2026 [3] [4].

Quick Reference — States That Have Eliminated the Transaction Count Threshold (Revenue Only):
A major trend in 2025 and 2026 is the elimination of the 200-transaction threshold, simplifying compliance for low-dollar, high-volume sellers. States that have dropped this requirement include Alaska (local, Jan 2025), California, Colorado, Illinois (Jan 2026), Indiana, Iowa, Louisiana, Maine, Massachusetts, North Carolina, North Dakota, South Dakota, Utah (Jul 2025), Washington, Wisconsin, and Wyoming. Kentucky will remove its transaction threshold on August 1, 2026 [5].
A marketplace facilitator is a platform (like Amazon, Etsy, eBay, or Walmart) that facilitates retail sales by connecting buyers and sellers, processing payments, and handling the transaction. Under marketplace facilitator laws, the platform is legally required to collect and remit sales tax on behalf of third-party sellers. As of 2026, all 45 states with a sales tax (plus Washington D.C.) have active marketplace facilitator laws in effect.
Marketplace facilitator laws protect sellers on those platforms, but if a seller also runs their own DTC (direct-to-consumer) storefront (Shopify, WooCommerce, etc.), they are still directly responsible for nexus compliance on DTC channel sales. This is a commonly misunderstood point.
We often see new brand founders at Branvas who sell on Amazon assume they have zero sales tax exposure. Then they launch their own Shopify storefront and realize they've been accumulating economic nexus in multiple states unchecked.

Shopify provides built-in tools to help sellers manage sales tax, but it is crucial to understand their limitations. Shopify handles automatic tax calculation at checkout and provides nexus registration reminders, but it does not automatically register you with the state or file your returns for you unless you use specific paid add-on services.
To configure your nexus states in Shopify, navigate to Settings → Taxes and duties → United States. Here, you can add the states where you are registered to collect sales tax. Shopify will monitor your sales and alert you when you are approaching or have crossed an economic nexus threshold in a new state.
However, Shopify calculates and collects but does NOT file returns on your behalf by default. For sellers in 5+ nexus states, a dedicated compliance tool like TaxJar, Avalara, or Vertex is strongly advisable to automate the filing process and ensure accuracy.
If you're launching a new ecommerce brand and want to structure your fulfillment and operations cleanly from day one, Branvas's how-it-works page walks through how we set up blind-ship fulfillment in a way that keeps your physical nexus footprint minimal and predictable.
Once you register for a sales tax permit in a state, the state revenue department will assign you a filing frequency. The three standard filing frequencies are annual, quarterly, and monthly. States assign this frequency based on your sales volume or projected tax liability in that state.
Filing frequency can change year-to-year as your volume in a state grows. High-volume states like California, New York, and Texas have particularly aggressive monthly filing requirements or prepayment schedules at higher revenue thresholds.
Many sellers focus obsessively on whether they've hit the nexus threshold, but the bigger operational trap is filing frequency mismanagement after registration. Specifically, failing to file zero returns in states that require them can compound into significant penalty exposure over 12 to 24 months [6].
Missing a filing deadline, even with $0 tax owed (a "zero return"), can trigger penalties in many states. States like Colorado, Florida, Illinois, and Texas require you to file a return to report zero sales, and failing to do so can result in late fees ranging from $50 to percentage-based penalties.
Q: What is the most common economic nexus threshold across US states?
A: The most common economic nexus threshold is $100,000 in gross sales revenue. While many states previously included a 200-transaction threshold alongside the revenue limit, a significant trend in 2025 and 2026 is the elimination of the transaction count requirement.
Q: Do I owe sales tax in a state if I only sell through Amazon FBA?
A: If you sell exclusively through a marketplace facilitator like Amazon, the platform is responsible for collecting and remitting sales tax on your behalf in all states with active MF laws. However, you may still need to register and file zero returns depending on the state's specific requirements.
Q: How do I know when I've crossed the economic nexus threshold in a state?
A: You must monitor your gross sales and transaction counts by state over the current or previous calendar year. Ecommerce platforms like Shopify provide nexus tracking dashboards, and tax automation software like TaxJar or Avalara can alert you when you approach a threshold.
Q: What happens if I exceeded the threshold last year but didn't register — am I liable for back taxes?
A: Yes, if you exceeded the threshold and failed to register, you are generally liable for the uncollected taxes, plus potential penalties and interest. Some states offer Voluntary Disclosure Agreements (VDAs) that allow you to come forward and pay back taxes with reduced penalties.
Q: Does Shopify automatically file my sales tax returns?
A: No, Shopify's core platform calculates and collects sales tax at checkout, but it does not automatically file your returns with the state. You must either file manually, use Shopify's paid filing service (if eligible), or integrate a third-party tool like TaxJar or Avalara.
Economic nexus is now the law in every sales-tax state post-Wayfair. Thresholds, transaction rules, and filing frequencies vary significantly, so bookmark the master table above to stay compliant in 2026. While marketplace facilitator laws reduce exposure for multi-channel sellers, they do not eliminate the obligations for your own DTC storefront. As your brand scales, automation tools become essential, as manual tracking is viable only for very early-stage sellers.
