When Do Businesses Need to Collect Kentucky Sales Tax?
Businesses are required to collect sales tax in Kentucky if they meet the nexus criteria. Nexus refers to a business’s connection to the state; it triggers the obligation to collect and remit sales tax. Understanding the sales tax nexus is key to knowing when your business must collect and remit tax.
There are two primary types of nexus:
- Physical Nexus
If your business has a physical presence in Kentucky, such as a warehouse, office, or employees working in the state, you are required to collect sales tax. If your business operates in Kentucky, you might be subject to physical nexus sales tax obligations.
- Economic Nexus
Kentucky also follows the economic nexus rule. If your business makes over $100,000 in gross sales or 200 separate transactions with Kentucky customers in a year, you are required to collect sales tax, regardless of whether you have a physical presence in the state. (Source: Sales Tax Institute)
For example, an out-of-state online retailer selling more than $100,000 in goods to Kentucky residents will trigger economic nexus and would thus be required to collect Kentucky sales tax.
If you’re an online seller, it’s important to know about sales tax thresholds and when you’re required to collect tax.
Failure to Collect Kentucky Sales Tax
Failure to comply with tax regulations can lead to penalties. Learn why sales tax is important for businesses and the consequences of non-compliance.
