Kentucky
Employee Obligations (Which Returns YOU Must File)
Since Washington has no income tax, you won't face double taxation. However, if you physically work in Kentucky, you may owe Kentucky income tax (Flat 4.0% (2025), 3.5% (2026)) and need to file a nonresident Kentucky return.
Employer Obligations (What Your Employer Must Withhold & Remit)
Register for withholding and unemployment from day 1. Must also register with local tax authorities. Unemployment applies to the first $11,400 of wages.
City & Local Income Taxes (Extra Filings Beyond the State Return)
87 counties and approximately 170 cities levy occupational taxes on nonresidents ranging from 0.5% to 2.5%. City and county taxes can stack. Louisville Metro charges 1.45% for nonresidents. Lexington-Fayette charges 2.25%. Combined state plus local total can exceed 6%. The M1CR credit does NOT cover these local taxes.
