Selling online has plenty of benefits, but it also comes with challenges—like managing refunds. Ecommerce businesses often see higher return rates than brick-and-mortar retailers, which can create added operational costs and complexity.
Refunds can also raise sales tax questions. If your business is close to an economic nexus threshold in a state, you may wonder: Does a refunded order still count toward that threshold?
The answer depends on the state and on the type of threshold you are measuring. Here’s what ecommerce sellers should know.
Since the 2018 South Dakota v. Wayfair Supreme Court decisio n, states can require remote sellers to collect and remit sales tax when their economic activity in the state exceeds certain thresholds. This is referred to as economic nexus .
These thresholds vary by state, but they commonly consider one or both of the following:
For example, a state may require a business to register once it reaches a certain amount of sales, a certain number of transactions, or either (or both!) threshold. Because rules vary, and can change, businesses should evaluate their activity based on each state’s current requirements.
A refund generally does not create a new transaction. However, that does not necessarily mean the original order disappears from your nexus calculation.
The treatment of a refunded sale can depend on:
A completed sale that is later refunded may still be relevant to a transaction-count threshold. Meanwhile, the refunded amount may affect the sales dollars used to evaluate a sales-based threshold. The specific treatment depends on the state.
It’s important to distinguish between these two different thresholds.
For a revenue threshold, a refund may reduce the amount of sales your business reports for a state. For example, if a customer makes a $500 purchase and later receives a full refund, that refunded amount may reduce your sales total, depending on the applicable state rules and timing.
Partial refunds can also matter. If you refund only part of an order, only the refunded portion may reduce the sales amount used in your calculation.
For a transaction threshold, the original completed sale may still count as one transaction, even if the customer later returns the item and receives a refund.
For that reason, businesses close to a transaction threshold should not assume that refunded orders can be removed from their transaction totals. Instead, they should review the requirements for the specific state where the sale occurred.
Not every refund situation is the same. Here are a few common examples. This chart explains common scenarios, but you should confirm with the state since rules vary.
If your business exceeded a state’s nexus threshold earlier in the year, a later refund may reduce taxable sales or affect the amount reported on a sales tax return. But it may not erase an obligation that has already been triggered.
For example, if you exceed a state’s threshold in June and issue a large refund in August, you may still need to register, collect, and remit sales tax based on the state’s rules.
Not always. The correct reporting process depends on the state, the timing of the refund, and whether the original sales tax return has already been filed.
In some cases, a business may be able to account for refunded sales tax on a later return. In others, an amended return or refund claim may be appropriate. Businesses should keep records showing:
If a refund could affect your filing requirements or nexus status, consider speaking with a tax advisor.
Economic nexus management requires more than tracking total sales. To understand where your business may have sales tax obligations, you need visibility into sales activity, transaction counts, refunds, exemptions, marketplace sales, and each state’s rules.
TaxJar’s Nexus Insights Dashboard helps businesses monitor their economic activity across states and identify where they may need to register and collect sales tax. The dashboard evaluates eligible sales activity against applicable nexus thresholds, while helping businesses account for factors such as wholesale, marketplace, free, and refunded orders where relevant.
Refunds are imported into TaxJar and appear as negative amounts on the Transactions page, giving businesses a clearer view of their sales activity. Learn more about how TaxJar handles refunds .
