Understanding Kentucky Taxes
When calculating your total tax liability in Kentucky, it's important to consider all three major components of the US tax system:
1. Federal Income Tax
Federal income tax applies to all US taxpayers regardless of state. The federal tax system uses progressive tax brackets, meaning higher income levels are taxed at higher rates. For 2025, federal tax rates range from 10% to 37%.
2. Kentucky State Income Tax
Kentucky imposes a state income tax on residents and non-residents who earn income within the state. State tax rates and regulations vary significantly from federal taxes, with different brackets, deductions, and credits available.
3. FICA Taxes
FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare. These taxes are:
- Social Security Tax: 6.2% on income up to $168,600 (2025 limit)
- Medicare Tax: 1.45% on all income
- Additional Medicare Tax: 0.9% on income over $200,000 (single) or $250,000 (married filing jointly)
