What Creates Nexus in Kentucky?
A business has nexus in Kentucky if it has any of the following:
-
Physical presence in the state (offices, stores, warehouses)
-
Employees or representatives working in Kentucky
-
Property (owned or leased) in Kentucky
-
Economic presence exceeding certain thresholds
Economic Nexus Standards
Kentucky follows economic nexus standards where a business has nexus if it has either:
-
Sales exceeding $100,000 to Kentucky customers, or
-
200 or more separate transactions with Kentucky customers
Public Law 86-272 Protection
Some businesses may be protected from Kentucky income tax under Public Law 86-272 if their only business activity in Kentucky is the solicitation of orders for tangible personal property, where such orders are approved and shipped from outside the state.
Key Considerations
-
Once nexus is established, businesses must register with the Kentucky Department of Revenue
-
Regular filing requirements apply even during periods of minimal or no activity
-
Nexus can be created through temporary or seasonal presence in the state
-
Different nexus standards may apply for other Kentucky taxes
