Kentucky payroll taxes for employers (2026)

Kentucky payroll: the local tax layer and other quirks

Local occupational license taxes are the main reason Kentucky payroll goes wrong. Each city, county or school district can levy one, the rate varies, some places may cap the wage base (we did not verify which), and in some places the employer pays part. Lexington-Fayette charges 2.25% of compensation. Louisville Metro requires employers to withhold its tax and file quarterly W-1 returns, though we did not confirm its current rate. Before you hire, find out which jurisdictions the work happens in. Our Kentucky local occupational tax guide collects what we could verify.

• Flat state tax: 3.5% for 2026 with a $3,360 standard deduction in the 2026 withholding formula.
• Construction pays the top rate: a new construction employer pays the highest rate on the schedule in effect. Schedule A, used for 2026, tops out at 9.00%.
• Three years at 2.70%: new employers stay at 2.70% or more until they have three years of experience.
• Workers comp from one employee: family, temporary and part-time workers all count. Out-of-state employers need a policy written with Kentucky coverage; an all-states endorsement does not qualify.
• Final pay: due by the later of the next normal pay period or 14 days after separation, quit or fired (KRS 337.055).
• PEOs: the state UI guide refers to employee leasing through certified PEOs. Harbor Compliance, a secondary source, says the Department of Workers' Claims handles registration. We found no public list.

Kentucky has no state paid leave or disability payroll program.

Kentucky employer cost on a $50,000 salary

For a new, non-construction employer, the 2026 bill looks like this.

A new construction employer at 9.00% pays 9.00% x $12,000 = $1,080.00 in SUTA, for $4,947.00 in total. The Kentucky rate range for experienced employers is 0.00% to 9.00% in the state guide; the US Department of Labor table shows a 0.30% floor, so check your own rate notice. See how Kentucky compares on the 2026 SUTA rates by state.

What changes for Kentucky employers in 2027

Senate Bill 129 brings back the Service Capacity Upgrade Fund for 2027 at 0.0115%. It was 0.0% in 2026 because the fund sat at its $60 million cap. If the wage base stays at $12,000, that adds 0.0115% x $12,000 = $1.38 per employee. The 2027 wage base, rate schedule and new employer rate were not published when we checked in October 2026; Kentucky law caps the base at $12,000.

Choosing a Kentucky payroll service or PEO

Ask any provider which Kentucky local taxes it files for you and which it leaves to you: withholding the tax and filing the local returns are separate jobs, and you need both covered. Our payroll software rankings list monthly prices, and the true cost of payroll services shows the add-on fees. If you want workers comp and benefits under one contract, compare PEOs by score.
