Kentucky payroll calculator employers use for figuring federal taxes
First and foremost, we have to give Uncle Sam his due. We’ll go through a quick overview of what you need to know when it comes to calculating federal payroll taxes. If you would like to see a more detailed explanation, head on over to our comprehensive guide on how to calculate payroll tax.
- Calculate Gross Wages:
- For all your hourly employees, multiply their hours worked by the pay rate. Don’t forget to increase the rate for any overtime hours.
- For all your salaried employees, divide each employee’s annual salary by the number of pay periods you have.
- Don’t forget to add in other forms of compensation, such as commissions, tips, or bonuses, into gross wages.
- Calculate Any Pre-Tax Withholdings: If your employees contribute to HSA, 401(k), or other pre-tax withholdings, deduct the appropriate amount from their gross pay before you calculate payroll taxes.
- Deduct Federal Income Taxes: Federal taxes can range anywhere from 0% to 37% of taxable earnings. We won’t get into all the nitty-gritty details here, but you can find further withholding information through the IRS website.
- Deduct and match any FICA taxes:
- Social Security tax, which is 6.2% of each employee’s taxable wages up until they reach $176,100 for the year. Employers also have to pay a matching 6.2% tax up to the wage limit.
- Medicare tax, which is 1.45% of each employee’s taxable wages up to $200,000 for the year. For any wages above $200,000, there is an Additional Medicare Tax of 0.9%, which brings the rate to 2.35%. Employers have to pay a matching 1.45% of Medicare tax, but only the employee is responsible for paying the 0.9% Additional Medicare Tax.
- Calculate the FUTA Unemployment Tax, which is 6.0% of the first $7,000 of each employee’s taxable income. Note that if you pay state unemployment taxes in full and on time, you are eligible for a tax credit of up to 5.4 %, which brings your effective FUTA tax rate to 0.6%. Only employers are responsible for paying the FUTA tax, not employees.
- Subtract Post-Tax Deductions, which can be anything from court-ordered wage garnishments to child support. Most of your employees won’t have post-tax deductions, but you still need to look out for them.
Kentucky state payroll taxes
Now that we’re done with federal taxes, let’s talk about Kentucky state taxes, shall we? The state used to have a range of tax rates, but it simplified the tax code and now charges a flat rate of 4.5% for all residents. In addition, depending on where in Kentucky your employees live or work, certain cities also levy local occupational taxes. You can view a list of tax districts on the Secretary of State’s website.
Kentucky state unemployment insurance (SUI)
As an employer, you’re responsible for paying state unemployment insurance, which covers those unemployed through no fault of their own. The wage base is $11,700 for 2025, and rates range from 0.3% to 9%
If you’re a new employer, you’ll pay a flat rate of 2.7%. Unless you’re in construction, then your rate is 9%.
Remember, paying your SUI in full and on time qualifies you to get a whopping 90% off of your FUTA tax bill, so make sure you pay attention to the due dates.
Staying compliant

And down the stretch, you come! All that’s left to do after calculating your employee’s net pay is cut those checks. Just make sure you’re setting aside the amount your company needs to pay to avoid any FICA and UI tax fiascos. You will need to use Form 941 to file federal taxes quarterly, and Form 940 to report your annual FUTA tax. You can pay taxes online using the EFTPS payment system. More details about employment tax due dates can be found here.

More helpful payroll calculators for Kentucky employers
Kentucky employers can use the calculator at the top of this page to quickly calculate their employees’ gross pay, net pay, and deductions in a few clicks. But sometimes there’s a little more math to do before they are able to cut paychecks. For instance, do you own a business where employees earn tips from customers? Keep in mind that you must also withhold taxes from your employees’ paychecks based on the tips they receive. Also, if you have workers who leave from time to time, you may need to spend some time calculating their final paychecks. So, if you need a little more help with the number-crunching, check out some of the calculators below.
