The economic nexus rules that emerged after the 2018 Wayfair Supreme Court case have created a hidden compliance minefield for crypto payment processors. In short, the case, and the rules that have followed it, now mean that digital businesses may be required to collect sales taxes in states they’ve never stepped foot in.
While most crypto firms focus on federal tax obligations and 1099-DA reporting, they often overlook the fact that processing crypto payments can trigger sales tax registration requirements in multiple states simultaneously.
Unlike traditional payment processors that mainly handle fiat transactions, crypto payment companies face unique challenges because their high-volume, cross-border transaction patterns can quickly exceed state thresholds without any physical presence. This creates a situation where a crypto payment processor based in Wyoming could suddenly find themselves with tax obligations in dozens of states based purely on their transaction flow.
What Economic Nexus Means for Your Crypto Payment Business
Before the 2018 Wayfair Supreme Court decision, businesses were only required to collect sales tax in states where they had a physical presence, such as an office, warehouse, or employees. The ruling established the concept of economic nexus, allowing states to require businesses to collect and remit sales tax based solely on their economic activity in the state—such as reaching a certain threshold of sales or transactions—even if the business has no physical presence there.
For crypto payment processors, this means that facilitating transactions for customers in various states can create tax obligations even if your company has no offices, employees, or property in those states.
Most states have adopted economic nexus thresholds around $100,000 in sales revenue or 200 transactions annually, though some states like Texas have higher thresholds. The challenge for crypto exchanges and companies is that transaction volumes can escalate quickly across multiple states. A processor that starts the year with minimal activity in a particular state can suddenly find themselves well over the threshold by mid-year due to increased adoption or a few high-volume clients.
Here’s an example. Consider a Ohio-based crypto payment processor that handles transactions for e-commerce merchants accepting Bitcoin and Ethereum. They might process $50,000 in transactions for Florida customers in January and another $60,000 in February. By March, they've crossed Florida's $100,000 threshold and are legally required to register for Florida sales tax, begin collecting tax on applicable transactions, and file regular returns.

💡 Key Insight: Unlike traditional businesses that might gradually expand into new states, crypto payment processors can suddenly find themselves with nexus obligations in dozens of states based on transaction flow patterns they may not have anticipated.

The Hidden Complexity of Crypto Payment Nexus
Crypto payment processors face several unique nexus complications that traditional payment companies don't encounter:
- Volume Risk: The volume of crypto transactions flowing through payment processors is expected to surpass $2 trillion globally in 2025, meaning high-volume processors can quickly exceed state thresholds without realizing it.
- Geographic Concentration: Processors often see concentrated activity in crypto-friendly states like Wyoming, Florida, Texas, and New Hampshire while still having customers nationwide, creating uneven distribution patterns.
- Regulatory Uncertainty: Most states do not yet have clear guidance or legislation on sales tax for crypto transactions, creating a patchwork of conflicting rules. Of the few states that do provide guidance, some treat crypto as equivalent to cash in transactions and tax it accordingly, while others like Arkansas and Washington have determined that digital currencies aren't subject to sales taxes. This patchwork of regulations creates uncertainty about when and how nexus obligations apply.
The lack of clear state guidance creates additional complexity because processors must make compliance decisions without definitive rules. However, this uncertainty doesn't eliminate nexus obligations. Processors must still track their activity across states and be prepared to register when thresholds are exceeded, even if the taxability of their specific services remains unclear.
The Real Cost of Compliance
Once you've established nexus in a state, the obligations extend far beyond simply registering for a sales tax permit. After registration, you'll need to collect and remit sales tax on taxable sales made in each state where you have nexus. This means implementing systems to track transactions, calculate the correct tax rates for different jurisdictions, and collecting sales tax payments from users.
Filing requirements vary by state. Most states require quarterly filing and payment of sales and use tax, though some require monthly filings while others may allow annual filings. Each state has its own forms, deadlines, and specific requirements for how transactions must be reported. A processor with nexus in ten states might need to file forty returns per year, each with different requirements and deadlines. It’s an area where things can get complicated fast, and it’s important you’ve got a great CPA in your corner.
The operational burden includes several key areas:
- Record Keeping: You'll need detailed records of all sales and taxes collected, including transaction amounts, customer locations, tax rates applied, and exemptions claimed.
- System Requirements: Many processors discover their existing systems aren't designed to capture and organize information in the format required for sales tax compliance.
- Penalty Exposure: Businesses that fail to comply may face penalties and interest charges that can reach 25% of unpaid tax, plus interest exceeding 12% annually.

💡 Key Insight: Registration is just the beginning – ongoing compliance requires systems to track taxable transactions, calculate correct rates, and file regular returns in each state where you have nexus, creating an operational burden that many processors underestimate.

Why Crypto Payment Processors Are Particularly Vulnerable
Several factors make crypto payment processors especially prone to unexpected nexus obligations:
- Rapid Growth Patterns: Crypto adoption can create sudden spikes in transaction volume that push processors over thresholds quickly, especially during market surges or new client acquisitions.
- Wide Geographic Spread: Many crypto companies operate on a nationwide or international scale,giving them a far broader geographic distribution than traditional payment processors.
- Federal Compliance Focus: Most crypto firms prioritize federal tax compliance and broker reporting while overlooking state sales tax obligations.
- Evolving Business Models: Processors that start with simple payments might expand into staking services, DeFi integrations, or NFT marketplace support, each with different nexus implications.
Managing the Risk
The good news? You can manage sales tax nexus risk if you start tracking the right information early. The key is setting up systems that capture transaction volume and revenue by state from day one. This means knowing not just how much you're processing, but where your customers are located and what services you're providing them.
You also need to stay on top of the different rules across states. While most states hover around $100,000 or 200 transactions as their trigger points, the details matter. Some states count different types of transactions, others have different deadlines, and the rules keep changing as more states update their policies.
When you do cross a threshold, don't wait to register. Some states offer programs that can reduce penalties if you come forward before they find you, but you'll still likely owe back taxes and interest. The longer you wait, the more expensive it gets.
Needless to say, this is a complex topic that changes frequently. Working with advisors who understand both crypto businesses and multi-state tax rules is a worthwhile investment. The intersection of crypto regulation and state sales tax isn't something most general accountants deal with regularly, so it’s important to find specialized advisors.
