How to Do Payroll in Kentucky | Small Business Guide

Quick answer

Kentucky small businesses with W-2 employees generally need to withhold federal and Kentucky income tax, pay employer Social Security and Medicare, maintain unemployment accounts, and run payroll through a system that supports accurate filings and bookkeeping.

W-2 employees vs. 1099 contractors

The IRS uses behavioral control, financial control, and the type of relationship to determine whether a worker is an employee or an independent contractor. Workers who follow the business's schedule and methods, use its equipment, and work primarily for it may need to be treated as employees.

Misclassifying employees as 1099 contractors is a serious payroll error. It can result in back payroll taxes, penalties, and interest and can affect workers' eligibility for unemployment and workers' compensation.

W-2 employees: you control when, where, and how the work is done; you provide equipment and supplies; workers work primarily for you
1099 contractors: they set their own schedule, use their own tools, may work for multiple clients, and submit invoices for specific projects
Workers who report on a set schedule and follow company methods may be W-2 employees under IRS rules
Independent businesses hired for specific projects may qualify as 1099 contractors

Kentucky overtime basics

Federal law generally requires overtime pay of at least 1.5x the regular rate for non-exempt employees who work more than 40 hours in a workweek.

Businesses with seasonal peaks or field crews can exceed 40 hours during busy periods. Tracking actual hours and paying overtime correctly is a payroll compliance requirement.

Track actual hours worked per employee each week, not just estimated hours
Pay 1.5x for every hour over 40 in a single workweek
Daily overtime rules do not apply in Kentucky — only the 40-hour weekly threshold
Overtime costs should be captured in payroll and flow into crew labor costs in your bookkeeping

Kentucky payroll registration and filing

Before running your first Kentucky payroll, you need to register with the Kentucky Department of Revenue for employer withholding and with the Kentucky Career Center for unemployment insurance. Both registrations must happen before you process payroll — not after.

Kentucky employer withholding is filed and paid on a schedule based on how much the business withholds. Kentucky unemployment reporting is generally handled quarterly.

Kentucky Department of Revenue: register for employer withholding at revenue.ky.gov
Kentucky Career Center: register for unemployment insurance at kcc.ky.gov
Federal: apply for an EIN at irs.gov if you do not have one
File IRS Form 941 quarterly for federal payroll taxes
File Forms W-2 and W-3 by January 31 for all employees
Issue Form 1099-NEC by January 31 for all contractors paid over $600

How payroll flows into bookkeeping

For service and trade businesses, field labor may be classified as cost of goods sold when it is a direct cost of delivering the work. Office and administrative payroll is generally kept in operating expenses.

If crew wages end up in a general Payroll Expense account under operating expenses, your gross margin disappears from the P&L and you lose the ability to calculate what it costs to deliver each service.

Gross wages for field crews → Crew Labor (COGS)
Employer payroll taxes (FICA, FUTA, SUTA) on crew wages → Payroll Taxes - COGS or allocated proportionally
Office and admin staff wages → Wages - Operating Expenses
Workers' comp insurance → can be COGS for field workers, operating for admin
Payroll journal entries from your provider should match these accounts exactly

Frequently asked questions

Questions owners ask next.

Can I pay employees in cash?

Paying wages in cash is legal, but the withholding and reporting requirements still apply. You must withhold income tax, Social Security, and Medicare from cash wages, and deposit those taxes on your regular schedule. Paying cash without withholding or reporting is treated as unreported wages and can result in significant penalties.

What happens if I misclassify a crew member as a 1099 contractor?

The IRS can reclassify the worker as an employee and assess back payroll taxes — both the employee's and employer's share — plus interest and penalties. Kentucky can also assess state taxes and unemployment contributions. The IRS has a Voluntary Classification Settlement Program (VCSP) that lets employers come into compliance with reduced penalties, but it is better to classify correctly from the start.

How do seasonal employees affect my payroll taxes?

Seasonal employees are still W-2 employees. You must withhold and deposit payroll taxes for every paycheck, file quarterly 941s for quarters where you pay wages, and issue W-2s by January 31 even if the worker only worked for three months. You do not file a 941 for quarters where you paid no wages, but you must check the seasonal employer box on your 941 if you only operate seasonally.
