Running an ecommerce business used to be simpler. You sold stuff online, customers bought it, and sales tax? Well, that was mostly someone else’s problem. Those days are long gone, my friend. Welcome to the world of economic nexus laws by state 2025, where your online success can trigger tax obligations in states you’ve never even visited.
If you’re selling online and hitting decent revenue numbers, you need to understand these rules. They’re not going away, and ignoring them isn’t a strategy. Let’s dive into everything you need to know about economic nexus laws by state 2025, from the basics to the nitty-gritty details that could save you thousands in penalties.
Think of economic nexus as a digital footprint that creates tax obligations. Economic nexus is a connection between a state and a business that allows the state to require the business to register to collect and remit sales tax. It’s established when a business reaches a certain threshold of sales revenue and/or number of transactions in the state.
Here’s the thing that catches most ecommerce sellers off guard: you don’t need a physical presence anymore. No warehouse, no office, no employees. Just sales. Hit the magic number in a state, and boom – you’ve got sales tax nexus whether you like it or not.
This matters because sales tax compliance isn’t optional. States need revenue, and they’ve figured out that online sales represent a massive, previously untapped source. The digital economy has shifted how we think about legal obligations, and your business needs to adapt or face the consequences.
The Wayfair ruling flipped everything upside down for remote sellers. Before June 2018, physical presence ruled supreme. However, the landmark South Dakota v. Wayfair (Wayfair) decision fundamentally changed the rules, enabling states to impose tax collection requirements based on economic activity alone.
The Supreme Court essentially said, “Hey, if you’re making money in our state, you should be collecting our taxes.” It sounds reasonable until you realize this applies to all 45 states with sales tax, each with different rules, rates, and requirements.
The Wayfair decision didn’t just change tax law; it changed how online retail works. Suddenly, every ecommerce seller had to become a tax expert or hire one. The complexity multiplied overnight, and many businesses are still playing catch-up.
Economic nexus laws by state 2025 operate on thresholds. Cross the line, and you’re in. Stay under, and you’re free to ignore that state’s sales tax requirements. But here’s where it gets tricky – every state sets its own thresholds.
Most states use a dual approach: revenue OR transactions. Hit either number, and you’ve triggered nexus. The most common setup is $100,000 in sales OR 200 transactions in a calendar year. As of July 1, 2025, 15 states and counting have eliminated the 200-transaction threshold for economic nexus.
Why are states dropping transaction thresholds? Because tracking 200 transactions is a pain for small businesses, and states realized they were creating unnecessary compliance burdens. Revenue-only thresholds are cleaner and easier to track.
Here’s where understanding gross sales vs taxable sales for economic nexus becomes crucial. Some states count everything you sell, including tax-exempt items. Others only count taxable sales. This distinction can mean the difference between owing taxes and flying under the radar.
For example, if you sell $80,000 in taxable items and $30,000 in tax-exempt products, you might think you’re safe. But if the state counts gross sales, you’ve hit $110,000 and triggered nexus. Always check how each state calculates its thresholds.
Let’s break down what are the state-by-state economic nexus thresholds for online sellers in 2025. This isn’t just academic – these numbers determine your tax obligations.
Some states set higher bars for economic nexus. California maintains a threshold of $500,000 in gross annual sales or 100 transactions. New York follows a similar pattern with $500,000 in sales and 100 transactions.
These higher thresholds give smaller businesses more breathing room. If you’re doing $200,000 annually, California’s economic nexus laws won’t affect you yet. But don’t get comfortable – growth happens fast in ecommerce.
The majority of states stick with the $100,000 threshold. As of January 1st, 2025, Alaska removed its 200 transaction threshold to reduce compliance stress for smaller merchants. As of this writing, the $100,000 sales threshold remains for sellers transacting in Alaska.
This $100,000 number isn’t random. It came from the original South Dakota law that triggered the Wayfair case. Most states figured if it was good enough for the Supreme Court, it was good enough for them.
The trend toward revenue-only thresholds continues gaining momentum. States realize that tracking transactions creates administrative headaches without adding meaningful tax collection benefits. When you’re selling $5 items, hitting 200 transactions at $1,000 in sales doesn’t represent significant economic activity.
This shift actually helps small businesses. Instead of worrying about transaction counts, you can focus on revenue thresholds, which are much easier to track and predict.
Small businesses face unique challenges with economic nexus compliance. You’re probably not Amazon with a dedicated tax department. You’re likely a solo entrepreneur or small team trying to grow while managing an increasingly complex regulatory environment.
Here’s the uncomfortable truth: economic nexus laws don’t care about your business size. Hit the threshold, and you’re treated like any other business. There’s no “small business exception” or simplified process for micro-enterprises.
This creates a scaling problem. Your first $100,000 in a new state triggers the same compliance requirements as your ten-millionth dollar. The fixed costs of registration, filing, and compliance hit small businesses disproportionately hard.
$100,000 sounds like serious money until you break it down. That’s about $8,333 per month or $274 per day. For many ecommerce businesses, especially those selling higher-priced items, this threshold arrives faster than expected.
Consider this: sell a $50 product and you need 2,000 sales to hit nexus. Sell a $500 product and you only need 200 sales. The threshold becomes less intimidating and more inevitable as your business grows.
Dropshipping adds layers of complexity to economic nexus compliance. You’re selling products you never touch, often from suppliers in different states, to customers scattered across the country. This creates unique challenges for determining nexus and managing compliance.
In traditional retail, you know where your inventory sits. With dropshipping, products might ship from your supplier’s warehouse in Texas to your customer in Florida, while you operate from Colorado. Which state’s laws apply? All of them, potentially.
Your nexus obligations depend on where you make sales, not where products ship from. But product origin can affect tax rates and rules, especially for destination-based tax states.
Dropshippers often struggle with record-keeping because they don’t control the fulfillment process. You need detailed records of where sales occur, but your supplier handles shipping. This disconnect can create gaps in your compliance documentation.
The solution involves better integration between your systems and your suppliers’. You need real-time access to shipping data to maintain accurate nexus tracking and tax calculations.
Marketplace facilitator laws changed the game for sellers using platforms like Amazon, eBay, or Etsy. These laws require the platforms themselves to collect and remit sales tax on behalf of sellers. Sounds great, right? Well, mostly.
Major marketplaces now handle sales tax collection for transactions processed through their platforms. This removes a huge compliance burden from individual sellers. Amazon collects tax in all states where it’s required, regardless of whether individual sellers have nexus.
But here’s the catch: marketplace facilitator laws only cover sales through the platform. If you sell through Amazon AND your own website, you still have nexus obligations for your direct sales.
Marketplace facilitator protection isn’t universal. Some states exempt certain types of sales or require sellers to register even when the marketplace collects tax. You can’t assume platform protection covers all your obligations.
Plus, if you’re selling across multiple channels – marketplace, website, wholesale – you need to track nexus separately for each channel. It’s complicated, but that’s the reality of multi-channel ecommerce in 2025.
Sales tax calculation varies dramatically by state, and getting it wrong costs money. Some states use origin-based taxation, others use destination-based, and a few use hybrid systems that combine both approaches.
Destination-based states tax based on where the customer receives the product. Origin-based states tax based on where the sale originates. Sounds simple, but implementation gets messy fast.
California uses destination-based taxation, so a sale to a customer in Los Angeles gets taxed at LA’s rate, not your business location’s rate. Texas uses origin-based taxation, so your business location determines the tax rate for all Texas sales.
Cross-border sales add another layer of complexity. Interstate sales within the US follow domestic economic nexus rules, but international sales have different considerations entirely.
Some states exempt international sales from economic nexus calculations, while others include them. This affects whether you trigger nexus thresholds and what compliance obligations you face.
Once you trigger nexus, registration becomes mandatory. Each state has its own process, timeline, and requirements. Miss the deadline, and penalties start accumulating immediately.
Registration typically requires basic business information, projected sales volumes, and sometimes security deposits. The process varies from simple online forms to complex multi-step procedures requiring documentation.
Most states offer online registration, but processing times vary. Some approve immediately, others take weeks. Plan ahead because you can’t legally collect tax until you’re registered.
You must register once you meet nexus thresholds, but states differ on timing requirements. Some require immediate registration, others give grace periods. Getting this wrong triggers penalties before you even start collecting tax.
The safest approach is proactive registration. If you’re approaching nexus thresholds, register early rather than risk non-compliance penalties.
Managing economic nexus across multiple states requires tools. You can’t track everything manually without making costly mistakes. The question isn’t whether to use tools, but which ones fit your business.
Sales tax automation platforms like Avalara, TaxJar, and Vertex handle nexus monitoring, tax calculations, and filing requirements. They integrate with most ecommerce platforms and automatically track your sales across states.
These tools aren’t cheap, but they’re cheaper than penalties and manual compliance efforts. Expect to pay $50-500+ monthly depending on your sales volume and complexity requirements.
Manual processes work for very small businesses with limited state exposure. If you’re only dealing with one or two states, spreadsheets and careful record-keeping might suffice.
But automation becomes essential as you grow. Multiple states, varying tax rates, changing regulations, and regular filing requirements quickly overwhelm manual processes. The transition point varies, but most businesses need automation by the time they reach $500,000 in annual sales.
Penalties for economic nexus non-compliance stack up fast. Late registration, missed filings, incorrect calculations, and delayed payments all trigger separate penalty structures. Understanding common mistakes helps you avoid expensive surprises.
The most expensive mistake is ignoring nexus obligations entirely. Some businesses hope they’ll fly under the radar, but states are getting better at identifying non-compliant sellers. The penalty for willful non-compliance often exceeds what you would have paid in taxes.
Other costly mistakes include incorrect tax calculations, late filings, and inadequate record-keeping. Each creates separate penalty exposure and compounds your compliance problems.
Most states offer voluntary disclosure programs that reduce penalties for businesses coming forward voluntarily. These programs typically limit lookback periods and waive some penalties in exchange for future compliance.
If you discover past nexus obligations, voluntary disclosure usually costs less than waiting for the state to find you. It’s not fun, but it’s better than the alternative.
Economic nexus changes for online marketplaces in 2025 continue evolving as states refine their approaches. The trend toward simplification helps businesses, but staying current with changes requires ongoing attention.
Marketplace facilitator laws expanded in 2025, with more states requiring platforms to collect tax on behalf of sellers. This reduces individual seller obligations but creates new complexity around multi-channel sales.
Sales tax automation for ecommerce in 2025 isn’t luxury – it’s necessity. The complexity of managing multiple state obligations, changing rates, and varying rules makes manual processes unsustainable for growing businesses.
Modern automation tools handle nexus monitoring, tax calculations, registration management, and filing requirements. They integrate with popular ecommerce platforms and provide real-time compliance monitoring.
The investment in automation pays for itself through reduced penalty risk, time savings, and peace of mind. As economic nexus laws by state 2025 continue evolving, automated systems adapt faster than manual processes.
Economic nexus laws by state 2025 represent the new reality for ecommerce sellers. These laws aren’t going away, and compliance requirements will only increase as states refine their approaches and improve enforcement capabilities.
The key takeaways for your business: understand your nexus obligations across all states, implement systems to track sales and manage compliance, and stay current with changing regulations. Whether you handle compliance internally or outsource it, you need a proactive approach that scales with your business growth.
Don’t wait until you’re facing penalties to address economic nexus compliance. The cost of proactive compliance is always less than the cost of reactive penalty management. If you’re feeling overwhelmed by the complexity of economic nexus laws by state 2025, you’re not alone – and you don’t have to figure it out alone.

Small ecommerce businesses face the same compliance requirements as larger companies once they exceed state thresholds. There are no small business exemptions, which means even micro-businesses must register, collect, and remit sales tax once they hit $100,000 in sales or 200 transactions in most states.
Most states use $100,000 in annual sales as the threshold, though some high-threshold states like California and New York require $500,000. Many states have eliminated transaction thresholds, focusing solely on revenue. Alaska removed its 200-transaction threshold in 2025, keeping only the $100,000 sales requirement.
Sales tax calculation depends on whether the state uses destination-based or origin-based taxation. Destination-based states tax at the customer’s location rate, while origin-based states use your business location’s rate. You’ll need to determine each state’s approach and apply the correct local tax rates.
Dropshipping businesses face additional complexity because nexus depends on where sales occur, not where products ship from. You need detailed tracking of customer locations and may have obligations in multiple states regardless of where your suppliers are located. Record-keeping becomes more challenging without direct control over fulfillment.
Filing frequency (monthly, quarterly, or annually) is determined by each state, often based on your sales volume in that state, and will be communicated to you upon registration.
