Kentucky's income tax rates were last changed one year ago for tax year 2022, and the tax brackets were previously changed in 2018.
Kentucky has a flat income tax rate which applies to both single and joint filers. The Federal Income Tax, in contrast to the Kentucky income tax, has multiple tax brackets with varied bracket width for single or joint filers.
How do Kentucky tax brackets work?
Technically, you don't have just one "tax bracket" - you pay all of the Kentucky marginal tax rates from the lowest tax bracket to the tax bracket in which you earned your last dollar. For comparison purposes, however, your Kentucky tax bracket is the tax bracket in which your last earned dollar in any given tax period falls.
You can think of the bracketed income tax as a flat amount for all of the money you earned up to your highest tax bracket, plus a marginal percentage of any amount you earned over that. The chart below breaks down the Kentucky tax brackets using this model:
| For earnings over $0.00, you'll pay 4.5% plus $0.00 |
| For earnings over $0.00, you'll pay 4.5% plus $0.00 |

You can use the income tax estimator to the left to calculate your approximate Kentucky and Federal income tax based on the most recent tax brackets.
Keep in mind that this estimator assumes all income is from wages, assumes the standard deduction, and does not account for tax credits.

Kentucky Tax Deductions
When calculating your Kentucky income tax, keep in mind that the Kentucky state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.
Qualifying deductions might include an itemized deduction, the Kentucky standard deduction, exemptions for dependants, business expenses, etc.
Remember that Kentucky may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your Kentucky income tax return.

In addition to marginal tax brackets, one of the major features of the Kentucky income tax is deductions. The three most common deductions encountered by taxpayers are the Kentucky Standard Deduction, the Kentucky Personal Exemption, and the Kentucky Dependent Deduction. The current values of these deductions for tax year 2023 are as follows:
| Standard Deduction (Single) | Standard Deduction (MFJ) | Personal Exemption | Dependant Exemption |
|---|---|---|---|
| $2,770.00 | $5,540.00 | $0.00 * | $0.00 * |
The standard deduction, which Kentucky has, is a deduction that is available by default to all taxpayers who do not instead choose to file an itemized deduction.
The Personal Exemption, which is not supported by the Kentucky income tax, is an additional deduction you can take if you (and not someone else) are primarily responsible for your own living expenses. Likewise, you can take an additional dependent exemption for each qualifying dependent (like a child or family member), who you financially support.
The Federal income tax also has a standard deduction, personal exemptions, and dependant deductions, though they are different amounts than Kentucky's and may have different rules.
