Kentucky's tax framework for resident and nonresident remote employees is structured as follows:
-
Employer Withholding Obligations: Employers in Kentucky are required to withhold Kentucky Income Tax from the wages paid to employees, including both residents and nonresidents, as mandated by KRS 141.310. This includes adherence to regulations under KRS 141.315 that govern withholding practices.
-
Sourcing of Nonresident Wages: Nonresident individuals are subject to Kentucky income tax on wages earned from work conducted within the state. According to KRS 141.020(4), they are taxed only on the income derived from labor performed, business conducted, or services provided in Kentucky.
-
Reciprocity Agreements: Kentucky has reciprocity agreements with several states, specifically Illinois, Indiana, Michigan, Ohio, Virginia, West Virginia, and Wisconsin. These agreements allow nonresidents from these states to be exempt from Kentucky income tax on wages earned while working in Kentucky, provided their home state provides a similar exemption for Kentucky residents.
-
De-minimis Threshold: Kentucky does not have a specified de-minimis threshold for tax withholding. Instead, all wages paid to nonresident employees for work performed within the state are subject to withholding as required under KRS 141.310.
-
Local/City Wage Taxes: There are local and city wage taxes applicable in various jurisdictions within Kentucky. Employers must comply with local tax laws, which may vary significantly across different cities and counties.
Overall, Kentucky maintains a structured approach for taxing wages, with clear delineation of responsibilities for employers and specific regulations concerning nonresident taxation.
