What Is Kentucky Payroll Tax?
Kentucky payroll tax refers to the state and local payroll taxes that employers must withhold from employee wages or pay directly to state and municipal agencies. These taxes fund unemployment benefits and the state's, counties', and cities' income tax systems.
Kentucky's state-level system is straightforward a flat income tax rate and one unemployment tax but Kentucky has one of the most complex local tax structures in the country. Unlike most states, where local income tax (if any) is levied by cities alone, Kentucky authorizes both cities and counties to levy their own occupational license tax on wages, and the two can stack on top of each other. Kentucky payroll taxes are administered by two state agencies the Kentucky Office of Unemployment Insurance (unemployment insurance) and the Kentucky Department of Revenue (state income tax withholding) plus dozens of individual city and county revenue offices for local occupational license taxes.
Most Kentucky employers are responsible for the following payroll tax requirements:
- Unemployment Insurance (UI), administered by the Kentucky Office of Unemployment Insurance
- Kentucky Personal Income Tax withholding, administered by the Department of Revenue, at a flat rate
- Local Occupational License Tax, levied by most Kentucky cities and counties 87 of Kentucky's 120 counties levied one in 2025, and cities and counties can stack
Kentucky Payroll Taxes at a Glance
| Payroll Tax | Paid By | Purpose |
|---|---|---|
| Unemployment Insurance (UI) | Employer | Provides temporary income for eligible unemployed workers |
| Personal Income Tax (state) | Employee (withheld by employer) | Flat-rate state income tax withheld from employee wages |
| Local Occupational License Tax | Employee (withheld by employer) | Local tax on wages, levied independently by cities and/or counties the two can stack |
Understanding who pays each tax and that Kentucky's local tax is the norm rather than the exception, unlike Ohio or Alabama more limited local systems helps employers avoid the most common Kentucky payroll mistake: registering with the state but overlooking local registration entirely.
Kentucky Employer Payroll Tax Responsibilities
Every employer with workers in Kentucky has payroll tax responsibilities beyond simply issuing paychecks. Depending on your business, you'll generally need to:
- Register your business with the Kentucky Office of Unemployment Insurance and the Department of Revenue.
- Identify every city and county where employees work (and, in some cases, live), and register separately with each local jurisdiction that levies an occupational license tax.
- Withhold state income tax and applicable local occupational license tax from every paycheck.
- Pay employer UI contributions.
- File quarterly UI wage reports and periodic state withholding returns.
- Remit local occupational license tax withholding to each applicable city and/or county revenue office.
- Report every new hire and rehire to the Kentucky New Hire Reporting Center within 20 days.
- Maintain payroll records for state and local compliance.
Many businesses use payroll software with built-in Kentucky local tax lookups, since manually researching city and county rates for every work location is one of the most time-consuming parts of Kentucky payroll the state itself doesn't register you locally; that's on the employer.
Types of Kentucky Payroll Taxes
Unemployment Insurance (UI)
Unemployment Insurance is an employer-funded payroll tax administered by the Kentucky Office of Unemployment Insurance that provides temporary financial assistance to eligible workers who lose their jobs through no fault of their own.
Employers pay this tax directly it is never deducted from employee paychecks.
Kentucky assigns each new employer to a rate schedule based on the health of the state's UI trust fund; Rate Schedule A, in effect since 2019, remains in effect for 2026.
Key Facts
- Paid entirely by employers Kentucky has no employee UI contribution
- Calculated on an annual wage base that has increased for 2026
- New employers pay a flat 2.7% rate except new employers in the contract construction industry, who pay a substantially higher 9% rate
- Experienced employers under Rate Schedule A range from 0.3% to 2.4% for positive-rated employers, and 6.5% to 9% for negative-rated employers
- Most Kentucky employers receive a federal FUTA tax credit of up to 5.4% for timely state UI payment, bringing the effective FUTA rate down to about 0.6%
- Must be reported quarterly through the Kentucky Employer Web Enabled Self-Service (KEWES) portal
Kentucky Personal Income Tax (PIT) Withholding
Kentucky imposes a flat-rate personal income tax on wages, and the rate has been decreasing under a multi-year phased reduction schedule established by the state legislature dropping to 3.5% for 2026, down from 4.0% in 2024.
Employers are responsible for:
- Withholding the flat state rate from every paycheck, based on current Department of Revenue withholding tables
- Reporting withholding to the Kentucky Department of Revenue
- Depositing withheld taxes on a monthly or quarterly schedule, depending on the amount withheld
- Filing periodic withholding returns and an annual reconciliation, including W-2 filing with the state
Kentucky has reciprocal income tax agreements with Illinois, Indiana, Michigan, Ohio, Virginia, West Virginia, and Wisconsin. An employee who lives in one of these states but works in Kentucky generally doesn't owe Kentucky income tax withholding at all only their home state's tax applies.
Local Occupational License Tax
This is where Kentucky payroll gets genuinely more complex than almost any other state. Kentucky authorizes both cities and counties to levy their own occupational license tax on wages sometimes described as a "fee," but functioning as a real local income tax and unlike most states, these two layers can stack rather than one replacing the other.
Key rules employers need to know:
- 87 of Kentucky's 120 counties levied a county-level occupational tax in 2025, with rates commonly ranging from 0.5% to 2.5%
- Many cities within those counties layer an additional city-level occupational tax on top of the county rate a worker in Louisville, for example, can owe tax to both Louisville Metro Government and to Jefferson County's school board simultaneously
- Louisville Metro charges a combined 2.2% occupational license tax on residents' compensation, and 1.45% on non-residents working within Louisville Metro administered by the Louisville Metro Revenue Commission through Form W-1 (employer withholding) and Form OL-3 (annual net profits)
- Lexington's combined resident rate is approximately 2.25%; Covington has one of the highest single-jurisdiction rates in the state at 2.45%
- The statewide median local occupational tax rate is approximately 1.00%
- These taxes are generally based on where work is physically performed, though some jurisdictions' school-board component doesn't apply to non-residents
- Employers must register separately with each applicable city and/or county revenue office the state does not handle this registration on the employer's behalf
- The Kentucky Secretary of State maintains an occupational tax database that employers can check to confirm which cities and counties currently levy this tax
Because this tax genuinely applies to the majority of Kentucky's counties (not just a handful of major cities, as in Ohio or Alabama), employers should treat local occupational tax lookup as a standard part of onboarding every Kentucky-based employee, not an edge case to check occasionally.
Which Payroll Taxes Are Paid by Employers vs Employees?
| Tax | Employer Pays | Employee Pays |
|---|---|---|
| Unemployment Insurance (UI) | YES | NO |
| Personal Income Tax (state) | NO | Withheld from wages (flat rate) |
| Local Occupational License Tax | NO | Withheld from wages (varies by city/county, can stack) |
Kentucky places the entire unemployment tax burden on the employer, while both layers of income tax state and local are withheld from employee wages.
Kentucky Payroll Tax Rates for Employers
Understanding current Kentucky payroll tax rates is essential for calculating payroll accurately. Third-party sources sometimes cite different figures for Kentucky's UI wage base always verify the latest numbers directly with the Office of Unemployment Insurance before processing payroll.
Kentucky Payroll Tax Rates at a Glance
| Payroll Tax | Who Pays | General Rate | Taxable Wage Base |
|---|---|---|---|
| Unemployment Insurance (UI) | Employer | New employers: 2.7% (9% for contract construction). Experienced employers under Rate Schedule A: 0.3%–2.4% (positive-rated), 6.5%–9% (negative-rated) | $12,000 for 2026, up from $11,700 in 2025 |
| Personal Income Tax (state) | Employee | Flat 3.5%, down from 4.0% in 2024, under a multi-year phased reduction | Applies to taxable wages, no brackets |
| Local Occupational License Tax | Employee | Statewide median roughly 1.00%; combined city+county rates reach 2.2%–2.45% in Louisville, Lexington, and Covington | Applies to wages earned in (and sometimes by residents of) a taxing city and/or county |
According to Bloomberg Tax's official coverage of the Kentucky Office of Unemployment Insurance's 2026 announcement, Kentucky's UI taxable wage base rose to $12,000 for 2026, and the state continues to use Rate Schedule A the same schedule in effect since 2019. Note that some third-party payroll guides cite a lower $11,100 wage base for 2026; this figure does not match the state's own official release and should not be relied upon always confirm the current wage base directly against the Office of Unemployment Insurance's published rate notice.
Instead of memorizing a specific rate, employers should focus on reviewing their annual UI rate notice, confirming current local occupational tax rates through the Kentucky Secretary of State's occupational tax database, and filing returns on time.
Understanding Taxable Wages
Not every Kentucky payroll tax applies to wages the same way. Depending on the tax involved, taxable wages may include:
- Hourly wages
- Salaries
- Bonuses
- Overtime pay
- Commissions
- Certain taxable fringe benefits
UI tax applies only up to the annual wage base, while state income tax and local occupational license tax generally apply more broadly to wages without the same wage base cap. Understanding which wage rules apply to which tax and which local jurisdictions apply to a given work location helps reduce calculation errors.
Kentucky Payroll Tax Filing Deadlines
Meeting payroll tax deadlines is just as important as calculating taxes correctly. Late filings or payments can lead to penalties and interest charges.
Unemployment Insurance (Quarterly Wage Report)
| Reporting Quarter | Filing Deadline |
|---|---|
| January – March | April 30 |
| April – June | July 31 |
| July – September | October 31 |
| October – December | January 31 |
State Income Tax Withholding
Kentucky withholding tax is filed monthly or quarterly, with the frequency assigned by the Department of Revenue based on the employer's total withholding liability.
Local Occupational License Tax
Filing frequency for local occupational license tax is set independently by each city or county revenue office commonly quarterly, though some jurisdictions (such as Louisville Metro) require both periodic employer withholding filings and a separate annual net profits return. Employers should confirm the specific schedule with each applicable local revenue office.
If a deadline falls on a weekend or holiday, it generally moves to the next business day. Given that Kentucky payroll can involve state and multiple local filings running on separate schedules, tracking them independently helps avoid missed deadlines.
How to Register for Kentucky Payroll Taxes
Before paying employees, businesses typically need to register at the state level, and separately with every applicable local jurisdiction.
State registration: Employers register for unemployment insurance through Kentucky Business One Stop, and separately with the Department of Revenue for state withholding tax.
Local registration: Employers must identify every city and county where employees work, check the Kentucky Secretary of State's occupational tax database to confirm which levy an occupational license tax, and register directly with each applicable local revenue office the state does not do this automatically.
During registration, you'll generally need information such as:
- Legal business name
- Federal Employer Identification Number (EIN)
- Business entity type
- Business address and all Kentucky work locations
- Owner or responsible party information
- Date employees first performed services in Kentucky
- Estimated payroll information

Step 2: Determine Applicable Local Jurisdictions
For each work location, confirm whether the city and/or county levies an occupational license tax, and whether the two stack.

Late filings or payments at the state or local level may result in penalties, interest charges, or other compliance issues. Filing accurately and on time across all applicable agencies helps avoid unnecessary costs.
Does Kentucky payroll tax apply to remote employees?
Yes, and local occupational license tax in particular depends on exactly where work is performed. Kentucky's reciprocal agreements with several neighboring states can also exempt certain nonresident employees from Kentucky state income tax withholding entirely, so this is worth reviewing carefully for any employee who lives out of state or works across multiple Kentucky jurisdictions.
Are Kentucky payroll tax rates the same every year?
Not always. Kentucky's UI wage base increased for 2026, and the state's flat income tax rate has been decreasing under a multi-year legislative phase-down. Local occupational license tax rates are set independently by each city and county and can change as well. Employers should review current Office of Unemployment Insurance, Department of Revenue, and local guidance each year before processing payroll.
Can payroll software calculate Kentucky payroll taxes automatically?
Many payroll platforms automatically calculate Kentucky UI contributions, flat-rate state income tax withholding, and local occupational license tax for major jurisdictions like Louisville and Lexington, and help employers meet filing deadlines. Given how much of Kentucky's complexity sits at the local level, this kind of automation is particularly valuable here though employers are still responsible for ensuring payroll information is accurate and up to date.
