Kentucky local income tax withholding is really occupational license tax withholding, and as an employer you handle it jurisdiction by jurisdiction: register with every city, county, and school district where your employees physically work, apply that jurisdiction’s rate to a compensation base that is broader than federal taxable wages, and file returns and payments with each local office on its own schedule. There is no single statewide filing. As of January 2025, 87 of Kentucky’s 120 counties impose an occupational tax on payroll, and hundreds of cities layer their own fee on top, with rates running from 0.50% to 2.5%.
What “Local” Means in Kentucky Payroll
Three separate layers of local government can tax the same paycheck: the county, the city, and the school district. Not every jurisdiction levies all three. County rates run from 0.50% to 2.5% with a median of 1%. City rates average roughly 1.47%, with a wide spread on either side. School district occupational taxes, authorized under KRS 160.605, add another line where they exist and are usually lower than the city or county rate.1FindLaw. Kentucky Revised Statutes Title XIII Education 160.605
These are occupational license fees, not income taxes, and the distinction changes who owes what. The tax follows the work, not the worker’s home address. An employee who lives in one county and commutes to a job in a different city owes the fee to the place where the work happens. That makes you, the employer, responsible for identifying the correct jurisdiction for each employee’s wages and remitting to that jurisdiction directly.
Finding the Right Rate for Each Employee
There is no current statewide list of rates, because each city, county, and school district sets and adjusts its own rate by local ordinance. You have to check with the finance office or occupational tax administrator in every jurisdiction where your employees work. The Kentucky Department of Education publishes annual data for school district rates.2Kentucky Department of Education. Taxes For city and county rates, the local ordinance is the source of truth.
When an employee works in a city that sits inside a county that also levies the tax, Kentucky law softens the double hit in larger counties. Under KRS 68.197, counties with populations of 30,000 or more must credit the county occupational tax for any city occupational tax already paid on the same income. If the city rate equals or exceeds the county rate, nothing more is owed to the county. If the county rate is higher, the employee owes the difference. Below that population threshold, the credit is not required. Some smaller counties offer it voluntarily; many do not, and city and county rates stack in full. Confirm the credit rule before you set up withholding for each work location.
What Wages the Tax Applies To
The taxable compensation base under the uniform system is wider than the federal taxable wage figure on a pay stub, and this is where employers most often get the math wrong. KRS 67.750 defines compensation as wages, salaries, commissions, and other remuneration for services reportable for federal income tax purposes, with two significant add-backs.3Justia Law. Kentucky Code 67 – Definitions for KRS 67.750 to 67.790
Pre-tax retirement contributions still count. Deferrals into 401(k), 403(b), 457, and similar plans reduce federal taxable wages but do not reduce the base for local occupational tax. The same is true for cafeteria plan deductions under Internal Revenue Code Sections 125 and 132, including health insurance premiums and flexible spending account contributions paid by salary reduction. Add those amounts back before applying the local rate.
Some jurisdictions cap the taxable compensation at the Social Security wage base, which is $184,500 for 2026.4Social Security Administration. Contribution and Benefit Base Others tax all earnings with no ceiling. The local ordinance controls, so check each one.
Register Before You Withhold
You need an account with every jurisdiction where your employees work, and you need it before you start withholding. Registration usually means a business registration form, a local account number, and sometimes a one-time fee. In Lexington, every person and business entity engaged in business within the county must obtain an occupational license before operating.5City of Lexington, Kentucky. Minimum License and Filing Requirements
Each jurisdiction issues its own account number, which then appears on every return you file with that office. Employees working across five cities and counties can mean five separate registrations. There is no centralized statewide portal for local occupational taxes; the Kentucky Department of Revenue handles state withholding only, and local jurisdictions administer their own systems.
Register early. Interest on unpaid taxes runs from the original due date, not from the day you finally sign up. If employees have been working in a jurisdiction for months before you register, you owe the tax retroactively along with any interest and penalties.
Quarterly Deposits and Monthly Thresholds
Most jurisdictions run on a quarterly filing cycle with these deadlines:
- First quarter (January through March): due April 30
- Second quarter (April through June): due July 31
- Third quarter (July through September): due October 31
- Fourth quarter (October through December): due January 31
Larger employers may have to file monthly. Lexington requires monthly filing when total withholdings in any quarter exceed $300.5City of Lexington, Kentucky. Minimum License and Filing Requirements Other jurisdictions set their own monthly thresholds. Confirm the frequency rule in each ordinance so you don’t accidentally file quarterly when the volume required monthly deposits.
Larger jurisdictions often accept electronic payment through their own portals. The Kentucky Department of Revenue’s taxpayer portal handles state employer withholding but specifically notes that online payment is not available for local tax bills.6Kentucky Department of Revenue. E-file and Payment Options Smaller offices may still require paper checks mailed to a specific address. Ask each jurisdiction how it wants to be paid when you register.
Annual Reconciliation and the Audit Window
After the fourth quarter you have to file an annual reconciliation tying total occupational tax withheld during the year to the W-2 data for each employee. Louisville’s annual reconciliation (W-3) and W-2 data for tax year 2026 are due by February 28, 2027.7LouisvilleKY.gov. Tax Calendar Most other jurisdictions follow a similar February 28 or March 15 deadline. The exact date is set by local ordinance.
The reconciliation is separate from state and federal W-2 filing, and it is not optional. The local office compares your quarterly deposits against annual totals and flags mismatches. Under KRS 67.775, the tax district has five years from the filing date to assess additional tax if it finds an underpayment. That extends to six years when the understatement exceeds 25% of what you reported, and there is no time limit at all where a return was never filed or was fraudulent.8FindLaw. Kentucky Revised Statutes Title IX 67.775
Remote and Multi-Location Employees
Kentucky taxes wages where the work is physically performed. That default creates real complexity for hybrid workers. An employee who spends three days in Lexington and two days in a home office in Boone County generates local tax liability in both jurisdictions, apportioned by the wages attributable to each location. There is no minimum-day threshold; withholding is owed from the first day an employee works in a taxing jurisdiction.
Tracking work locations day by day is the employer’s problem to solve. Many payroll platforms can allocate wages by location when the underlying records are accurate. When employees work from home, the tax follows them to their home jurisdiction rather than staying with your office. The legislature has looked at bills to clarify remote-work sourcing, but until something passes, work-situs is the rule.
Penalties for Late Filing or Nonpayment
Under KRS 67.790, an employer who misses a deadline faces 5% of the tax due for each month or partial month it goes unpaid, capped at 25% of the total, with a minimum of $25.9Justia Law. Kentucky Code 67 – 67.790 Penalties, Confidentiality of Information Filed With Tax District Simple interest accrues at 12% per year from the original due date until the tax is paid. Individual jurisdictions may layer their own penalty schedules on top; Kenton County, for example, applies 5% per month up to 25% with a $25 minimum per locality.10Kenton County, KY.

Willful violations move from civil to criminal. Deliberately failing to file, filing a false return, or collecting the tax from paychecks and not remitting it is a Class A misdemeanor under KRS 67.790, which in Kentucky carries up to 12 months in jail.9Justia Law.

State Withholding Is a Separate Track
Local occupational taxes are wholly separate from Kentucky state income tax withholding under KRS Chapter 141. The state rate for 2026 is a flat 3.5% on wages as defined by the Internal Revenue Code, filed with the Kentucky Department of Revenue through its taxpayer portal.11Kentucky Department of Revenue. Employer Payroll Withholding Filing state withholding correctly does nothing for your local obligations. If you skip the local returns, the notice comes from the city or county, and its penalties run on their own clock.
