Key takeaways
- Know your nexus: Understanding where your business has sales tax nexus—whether physical or economic—is essential to determining where you're required to collect and remit tax.
- Dropshipping complicates tax rules: Tax responsibilities can vary depending on the nexus status of both you and your supplier. Always clarify roles and use resale certificates properly to avoid double taxation.
- Automate compliance: Tax software can help dropshippers manage complex, multi-state sales tax rules, automate calculations, and ensure timely filing across jurisdictions.
In short: Dropshipping sales tax depends on nexus. If you, the retailer, have physical or economic nexus in your customer's state, you generally collect and remit the sales tax. If only your supplier has nexus, the supplier may charge you tax. Resale certificates help you avoid double taxation on goods you buy to resell.
In the fast-changing world of e-commerce, dropshipping has become a popular business model. It lets you sell products without holding inventory, which keeps upfront costs and risk low. But if you sell in the US, you must also deal with sales tax. Knowing your sales tax obligations keeps your business compliant and helps you avoid hefty penalties. Here's what sellers need to know about sales tax and dropshipping.

What is sales tax?
Sales tax is a consumption tax that the government charges on the sale of goods and services. The seller collects it at the point of sale and passes it on to the government. Sales tax rules can be complex, because they vary by state and even by locality. If you don't follow them, you can face serious financial and legal consequences.
What is sales tax nexus?
Sales tax nexus is the connection between a business and a state that requires the business to collect sales tax there. It is a key idea for US dropshipping businesses. In the past, a business created nexus through a physical presence in a state, such as a store, office or warehouse. With the rise of e-commerce, nexus now also covers economic presence.
Economic nexus means you may need to collect sales tax based on your economic activity in a state, even with no physical presence there. Each state sets its own economic nexus threshold, usually based on sales volume or the number of transactions.
For instance, a state might require you to collect sales tax once you exceed $100,000 in sales or 200 transactions in that state within a year. Learn these thresholds and keep monitoring your sales to stay compliant.
How does sales tax work for dropshipping?
In dropshipping, who collects sales tax depends mainly on whether the retailer or the supplier has nexus in the customer's state. Dropshipping adds another layer of complexity to sales tax. Three parties are involved: the retailer (you), the supplier and the customer. These factors decide who collects and remits the tax:
Retailer's nexus: If the retailer has nexus in the customer's state, the retailer usually has to collect and remit sales tax.
Supplier's nexus: If the supplier has nexus in the customer's state, the supplier may have to collect sales tax. In this case, the supplier may charge sales tax to the retailer, who then passes it on to the customer.
Drop shipment rules: Some states have specific drop shipment rules that differ from their general sales tax rules. For example, in some states, the supplier may need to collect sales tax on the retailer's behalf if the supplier has nexus but the retailer does not.
So talk to your suppliers to learn where they have nexus and how they handle sales tax. This prevents misunderstandings and makes sure the right amount of tax is collected and remitted.
How do resale certificates work in dropshipping?
Resale certificates let retailers buy goods for resale without paying sales tax, which helps avoid double taxation. Sales tax is then charged on the final sale to the end consumer. But states treat resale certificates differently, so check each state's specific requirements and paperwork.
Give your supplier a valid resale certificate when you buy goods for resale. This can exempt you from paying sales tax on those purchases. But make sure the certificates are filled out correctly and kept on file, because auditors will check them.

How do you stay compliant with sales tax as a dropshipper?
You stay compliant by finding where you have nexus, registering, collecting the right tax, filing on time and keeping records. In detail:
Determine nexus: Review your business activities regularly to see where you have nexus. This includes tracking economic nexus thresholds in each state. States often update their nexus laws, so stay informed.
Register for sales tax permits: Once you have nexus in a state, register for a sales tax permit there. This is a legal requirement and you need it to collect sales tax. Registration differs by state, so follow each state's guidelines.
Collect sales tax: Set up systems to collect the correct sales tax at the point of sale. This often means updating your e-commerce platform's tax settings. Many platforms, like Shopify, integrate with tax software that automates this and cuts the risk of errors.
File and remit sales tax: File sales tax returns and send the dropshipping taxes you collected to the right state authorities on time. Each state has its own filing schedule, which could be monthly, quarterly or annually. Missing a filing deadline can lead to penalties and interest.
Maintain records: Keep detailed records of all transactions, including the sales tax you collect and remit. You need these for audits and compliance. Good records also help you spot and fix mistakes quickly.
How can technology help with dropshipping sales tax?
Tax automation software helps dropshipping businesses calculate the right sales tax, follow each state's rules and prepare accurate filing reports. Sales tax compliance is complex, so technology can be a game-changer. The software works out the correct rate from the customer's location automatically.
These tools can also connect to your e-commerce platform, so you can manage sales tax across many channels more easily. Reliable tax software can save time, reduce errors and give you peace of mind that your sales tax obligations are handled well.
