Kentucky Payroll Tax Penalties & Interest Checklist
Kentucky payroll tax penalties and interest apply when employers fail to file payroll tax returns on time, pay payroll taxes when due, or deposit withheld taxes as required by the state. These penalties and interest charges are separate financial obligations added to the original tax debt under the Uniform Civil Penalty Act codified in Kentucky Revised
Statutes.
They matter because they increase the total amount owed and can accumulate quickly if the underlying tax issue is not resolved. Failing to pay Kentucky payroll tax penalties can lead to additional enforcement action by the Kentucky Department of Revenue, including liens, wage garnishments, or business license suspensions.
What This Issue Means
Payroll tax penalties and interest are extra charges the state adds when certain payroll tax obligations are not met. Penalties are percentage-based amounts assessed for late filing or late payment, calculated at 2% of the total tax due for every 30 days or fraction thereof that filing or payment is late.
Interest rate calculations are based on annual rates set by statute: 9% per year for calendar year 2026 and 10% per year for calendar year 2025. Both penalties and interest accumulate over time, making the total debt larger and appearing as separate line items on state notices or correspondence from the Kentucky Department of
Revenue.
Why the State Assesses Kentucky Payroll Tax Penalties
Kentucky assesses penalties and interest to encourage timely tax filing and payment under the Uniform Civil Penalty Act. When an employer fails to file a payroll tax return by the deadline or fails to pay taxes when due, the state automatically calculates and applies these charges.
The state uses penalties and interest as administrative tools to ensure compliance with tax law. Late payment of withheld employee taxes is treated seriously because these funds belong to employees, not the business, and are held in trust for the state under trust fund penalties provisions.
What Happens If This Is Ignored
If penalties and interest are not addressed, the debt will continue to grow as interest accrues based on the annual rate applied to the unpaid balance. The state may pursue additional collection actions, such as issuing a tax lien, intercepting state tax refunds, or garnishing wages from bank accounts.
Unresolved payroll tax debt can also result in business license suspension or revocation, affecting your Kentucky Business License. Kentucky law allows the state to take enforcement action without further notice once a tax debt is established, and corporate officers may face personal liability under Trust Fund Recovery Penalty provisions.
What This Does NOT Mean
Receiving a notice with penalties and interest does not mean criminal charges have been filed or that you are under investigation for tax fraud. It does not mean the business is automatically closed or that a lien has already been placed on property.
Penalties and interest are administrative charges, not judicial actions under Tax Evasion
Laws. The presence of penalties does not prevent you from working with the Kentucky
Department of Revenue to resolve the underlying tax issue or to discuss payment options and penalty abatement requests.
Emergency Response Checklist
Step 1: Locate and Review All Tax Notices
Gather every notice, letter, or bill from the Kentucky Department of Revenue related to
Kentucky payroll taxes. Read each document carefully to identify the tax period or quarters involved, the amount of tax owed, the amount of penalties assessed under the
Uniform Civil Penalty Act, the amount of interest charged, any stated deadline for response or payment, and the Department of Revenue contact information.
Step 2: Verify the Tax Period and Return Status
Check your business records to confirm whether payroll tax returns, including Form 941
(federal) and Kentucky Withholding Tax returns, were filed for the periods shown. Verify
whether tax payments were made and the dates of payment, whether deposits were made using your Kentucky Withholding Tax Account Number, and gather any documentation of correspondence with the state.
Step 3: Gather Financial and Payroll Records
Collect and organize payroll registers or records showing gross wages paid as well as employee withholding tax returns. Gather Form W-2 wage and tax statements issued to employees and bank statements showing deposits and payments through the Electronic
Federal Tax Payment System or other methods.
Compile records of any tax deposits made to the state, documents of any federal Form
940 or Form 941 filings, and documentation of any previous communication with the state. Include copies of Form K-4 (Kentucky employee withholding certificates) if relevant to the dispute.
Step 4: Contact the Kentucky Department of Revenue
Reach out to the Department of Revenue Customer Contact Center at (502) 764-5555 to confirm the details of the debt and request a detailed breakdown of taxes, penalties, and interest. Request clarification on which tax periods are involved, ask about the current total amount owed, and inquire about available payment options or resolution methods, including penalty abatement eligibility.
For employers in Louisville, you may also need to contact the Louisville Metro Revenue
Commission regarding local occupational tax obligations separate from state withholding requirements.
Step 5: Request a Detailed Accounting
Ask the Kentucky Department of Revenue to provide a written statement showing the original tax amount, the penalty calculation at 2% per 30-day period under the Uniform
Civil Penalty Act, the interest rate calculation based on the applicable annual rate (9% for 2026 or 10% for 2025), any credits or tax payments already applied, the current total balance, and any deadlines or required actions.
Step 6: Understand Penalty Abatement Options
Kentucky provides penalty relief through penalty abatement provisions for reasonable cause (circumstances beyond your control), first-time violations caused by human error, or situations where strict enforcement would cause undue financial hardship. This relief is separate from disaster relief provisions that may apply if your business was located in federally declared disaster areas.
Interest cannot be waived as it is required by statute. Prepare to submit a written request for penalty abatement with supporting documentation explaining the circumstances that prevented the timely filing or payment of Kentucky payroll taxes.
Step 7: Determine Your Current Ability to Pay
Assess whether you can pay the full amount, pay in installments over time through a formal payment plan, request a temporary delay in collection action, or request a hearing or appeal. Consider your business's financial condition and cash flow when evaluating payment options.
For severe financial hardship, you may inquire about an Offer in Compromise, though
Kentucky's program differs from the federal one. Provide complete financial documentation showing your employer obligations and current assets.
Step 8: Explore Payment Plan Options
Contact the Division of Collections at (502) 564-4921 to learn about formal installment agreement procedures and monthly payment amounts based on the total debt.
Understand that interest at the applicable annual rate will continue to accrue during a payment plan on any unpaid balance.
Ask about conditions for approval of a payment plan, how to apply, and whether you can file online or must submit paper forms. Ensure you understand payment identification requirements and methods accepted by the Kentucky State Treasurer's office.
Step 9: File a Formal Protest if Necessary
If you disagree with the assessment, you must file a written protest within 45 days from the date of the notice. The protest should clearly state why you believe the assessment is incorrect and include supporting documentation, such as payment records, copies of filed payroll tax returns (including Form K-5, annual withholding reconciliation), or other evidence.
After the Department of Revenue issues a final ruling, you may appeal to the Kentucky
Board of Tax Appeals. Missing the 45-day deadline makes the assessment final and eliminates your appeal rights.
Step 10: Document All Communication
Keep a record of the dates and times of phone calls to the Kentucky Department of
Revenue, the names of staff members you speak with, the topics discussed, and information provided, any commitments made by the state regarding tax relief or payment arrangements, and confirmation or reference numbers. Keep copies of all emails and written correspondence in a secure location at your business address (such as 501 High Street, if applicable) or registered office.
Step 11: Submit Required Response Within the Stated Deadline
If the notice specifies a deadline, take action by that date. Do not ignore the deadline, as this can result in additional penalties, loss of appeal rights, or accelerated collection action, including wage garnishments.
Submit any required forms or responses in writing, keep a copy of everything submitted, request written confirmation of receipt, and follow up if you do not receive acknowledgment within a reasonable time.
Step 12: Address the Underlying Tax Compliance Issue
Work to ensure that all required Kentucky Withholding Tax returns are filed going forward on time through electronic submission when needed. Ensure all payroll tax payments are made when due to the Kentucky Department of Revenue using your
Kentucky Withholding Tax Account Number.
Verify that all required deposits have been made to the state account, understand your filing and payment schedule based on your withholding amount, and implement systems to prevent future delays. Consider using the Electronic Submission portal or working with a payroll service to maintain compliance.

Step 13: Understand Corporate Officer Liability
If your business is incorporated, understand that Kentucky law imposes personal liability on corporate officers, managers of limited liability companies, and partners who exercise control or supervision over withholding tax functions. Officers with authority to direct payment of Kentucky Withholding Tax can be held personally and individually liable for unpaid taxes, penalties, and interest under Trust Fund Recovery Penalty provisions.
This personal liability applies regardless of corporate structure and can result in wage garnishments against individual accounts. Consult with legal counsel if you face potential personal liability assessments.
What Happens After This Is Completed
Once you have contacted the Kentucky Department of Revenue and provided information, the state will typically review your response and may issue additional correspondence or tax notices. If you request a payment plan, the Department of
Revenue will evaluate your request based on your financial situation, current employer obligations, and compliance history, then either approve or deny it with written terms.
If you request penalty abatement based on reasonable cause or first-time violation provisions, the Department of Revenue will consider your request according to
established criteria and respond with a decision. Interest continues to accrue on the unpaid balance at the applicable interest rate until the debt is paid in full.
Common Mistakes to Avoid
Missing response deadlines stated in tax notices can result in additional penalties or loss of appeal rights. Do not ignore the 45-day protest deadline if you disagree with an assessment under Kentucky Revised Statutes.
Failing to respond to the Kentucky Department of Revenue allows the state to proceed with collection action, including wage garnishments. Do not assume the issue will resolve itself without communication, as the state needs you to take action.
Not requesting a penalty abatement when eligible means missing out on tax relief. If your situation involved circumstances beyond your control or this is your first violation caused by human error, submit a written request with documentation.
Continuing to file late or miss tax payments for current periods while addressing existing debt creates additional Kentucky payroll tax problems. Ensure compliance with all
Kentucky Withholding Tax obligations, including resolving past issues.
Assuming personal liability does not apply is dangerous. Corporate officers with control over withholding functions face personal liability under Trust Fund Recovery Penalty provisions regardless of corporate structure.
