Kansas Payroll Tax Penalties & Interest Checklist
Introduction
Payroll taxes in Kansas primarily involve withholding tax deducted from employee wages and reported as part of Kansas income tax compliance. Employers act as collection agents for the
Kansas Department of Revenue, meaning withheld income tax belongs to the state and must be remitted by the applicable due date.
When withholding tax is not deposited, filed, or paid correctly, the Department of Revenue assesses a penalty and interest on the tax due. Understanding how Kansas payroll tax penalties apply helps employers limit exposure, correct filing issues, and avoid escalating enforcement.
What This Issue Means
Kansas payroll tax penalties and interest are additional charges applied when Kansas withholding tax obligations are not met on time. Withholding tax applies to wages paid to
Kansas residents and nonresident individuals for hours worked in Kansas. It is reported using filings such as Form KW-3, Form W-2, and related Wage and Tax Statement records.
Because withholding tax represents Kansas personal income tax prepayments, employers do not pay it themselves; they must remit it accurately. When deposits, electronic filing, or tax payments are late, penalty rates and interest increase the overall tax liability.
Why the State Issued This or Requires This
The Kansas Department of Revenue applies penalties and interest to enforce compliance with the Kansas withholding tax law and filing specifications. Interest applies to unpaid balances regardless of cause and is calculated using the annual interest rate set by the state.
Penalties are assessed under state payroll tax penalty rates based on the timing of payment, including tiered percentages and additional monthly charges. These rules promote timely compliance and support administrative oversight, payroll audits, and taxpayer assistance programs.
What Happens If This Is Ignored
If payroll tax penalties and interest are not addressed, the Department of Revenue may escalate collection activity. This can include additional notices, a returned check fee, tax liens, bank account levies, or enforced collection tied to the Kansas tax account number.
Interest continues to accrue on unpaid withholding tax, increasing the total tax due over time. In some cases, the state may review payroll filing responsibilities, especially when withholding tax was collected but not remitted.
What This Does NOT Mean
A penalty and interest notice does not mean criminal charges have been filed or that action by the Internal Revenue Service has begun. These are civil enforcement measures and are separate from federal payroll taxes or federal withholding obligations.
It also does not mean agencies such as the Kansas Department of Labor, the Kansas Secretary of State, or the Kansas Department of Commerce have taken licensing action. The notice reflects a compliance issue that still allows time for resolution.
Checklist: What to Do After Receiving This or Identifying
This Issue
Step 1: Gather withholding tax records
Collect notices from the Kansas Department of Revenue along with payroll records, Form KW-3 filings, KW-5 deposits, and W-2 forms. Include Form W-2c, 1099 series records, and documents showing federal withholding.
Step 2: Review notice details
Identify the tax periods involved, the withholding tax assessed, and the amounts listed for penalty and interest. Confirm the Kansas tax account number, employer identification number from Form SS-4, and stated due dates.
Step 3: Verify calculations
Compare state data with wage bracket tables, payroll information, and the percentage method of withholding. Confirm electronic filing submissions were accepted and applied correctly.
Step 4: Contact the Department of Revenue
Call the KDOR Customer Service Center using the contact details on the notice. Reference the notice number and the specific Kansas withholding tax periods involved.
Step 5: Request a detailed explanation
Ask how penalty rates and interest were calculated, including the interest rate applied and assessment dates—request written confirmation summarizing the explanation.
Step 6: Ask about relief options
Inquire about penalty abatement, credit memo application, or payment arrangements if the tax due cannot be paid immediately. Ask what documentation is required under the Kansas
Withholding Tax Guide.
Step 7: Obtain written instructions
Request written guidance outlining filing specifications, deadlines, and procedures for relief or payment plans. Retain copies for compliance records.
Step 8: Review payroll systems
Examine payroll processes, Kansas withholding tax registration status, and filing frequency.
Confirm proper handling of Kansas commissions, Kansas performances, and nonresident allocations.
Step 9: Implement corrective measures
Update payroll controls to ensure timely tax payments in accordance with the Kansas Tax
Calendar of Due Dates. Verify accurate reporting of Social Security Number data and wage and tax statement filings.
- State enforcement notices and responses
- Sales tax audits, assessments, and collections
- Payroll & trust fund tax enforcement issues
- Penalty and interest reduction options
- Payment plans and state tax relief eligibility
- Representation before state tax agencies
Step 10: Follow up in writing
Send written confirmation of any agreements or requests to the Kansas Department of
Revenue. Keep copies of correspondence and proof of electronic application or payment submission.
What Happens After This Is Completed
After review, the Kansas Department of Revenue issues a written response addressing penalty relief or payment arrangements. If approved, penalties may be reduced, though interest generally continues until the balance is paid in full.
If a payment plan is established, the state monitors compliance with ongoing withholding obligations. Failure to remain current can void agreements and restart enforcement actions.
Common Mistakes to Avoid
Missing deadlines listed on Department of Revenue notices often result in higher penalty rates.
Ignoring correspondence usually accelerates enforcement rather than delaying it.
Submitting incomplete documentation or assuming penalties cannot be reviewed delays resolution. Failing to correct payroll processes often leads to repeated payroll tax penalties.
