Kentucky Payroll Tax Registration

Oct 1, 2025

If you are an employer in Kentucky who has recently hired an employee, you will need to register for payroll taxes with the Kentucky Department of Revenue. This registration process ensures that you are compliant with state tax laws and able to properly withhold and remit taxes on behalf of your employees.

How Kentucky Payroll Registration Works

There are 2 payroll tax setup tasks you may need to complete in Kentucky to get your new hire on payroll for the first time. You can follow the guide below to help you get registered directly with the Kentucky agencies or use Mosey to do it.

Kentucky Unemployment Insurance Setup for LLC, Corporation, Professional Corporation, LLP

You are required to register for Kentucky Unemployment Insurance with the Kentucky Office of Unemployment if you pay $1,500 or more in wages during a calendar quarter, or have at least one employee during any part of 20 different weeks of a calendar year. Note: 501(c)(3) nonprofit organizations must register if they have four or more employees workers during any part of 20 different weeks of a calendar year. During the registration process, 501(c)(3) organizations will have the choice to either pay unemployment contributions on taxable wages each quarter or elect to reimburse the Kentucky Unemployment Fund (with interest) for benefits paid to terminated employees. The election to reimburse can only be changed after two calendar years.

Texas Break Laws Guide for Employers

Expanding into Texas means understanding the state’s unique approach to workplace breaks: there aren’t any requirements for adult employees. While many other states mandate specific meal and rest periods, Texas gives employers complete discretion over break policies, creating both opportunities and compliance challenges. This freedom isn’t as simple as it appears. Federal laws still apply, minor employees have special protections, and voluntary break policies must follow specific rules to avoid wage violations. So, navigating Texas’s flexible framework while maintaining federal compliance ensures your policies work for both business operations and employee satisfaction.

Understanding California’s Economic Tax Nexus Test

Tax nexus refers to a relationship between a business entity and a taxing jurisdiction. There are four main types: income tax nexus, sales and use tax nexus, franchise tax nexus, and excise tax nexus. If your business has one of these types of nexus in a state, you may need to pay the corresponding tax type there. Determining where you have each type of nexus is a critical—and complicated—compliance task. Nexus criteria and qualification thresholds vary by state. Some states also “test” for nexus in different ways.
