Choosing a PEO in Delaware
Delaware's minimum wage is $15.00 per hour, effective since January 1, 2025, with no further automatic increases currently scheduled. Overtime is paid at 1.5 times the regular rate for hours worked over 40 in a week, following the federal standard. Delaware is best known nationally as a corporate registration hub, but employers actually operating in the state face a distinct and increasingly active compliance landscape, not a light one.
Delaware's biggest recent change for employers is the Healthy Delaware Families Act, a state Paid Family and Medical Leave program. Payroll contributions began January 1, 2025, and employees became able to file benefit claims starting January 1, 2026 — meaning the program is now live and actively paying out. It applies to employers with 10 or more employees (employers with 10 to 24 employees owe parental leave coverage only; broader coverage applies at 25 or more). Benefits replace up to 80% of average weekly wages, capped between $100 and $900 per week, for up to 12 weeks of parental leave or 6 weeks of other qualifying leave within a 24-month period. Employers with fewer than 10 employees are exempt.
Delaware does not require PEOs to hold a state license, but PEOs and other third parties administering payroll or leave on a client's behalf must register on the state's LaborFirst platform — a step that has become more consequential now that Healthy Delaware Families Act contributions and claims are running through that same system. Workers' compensation insurance is mandatory for virtually all Delaware employers with one or more employees.
Delaware also has its own state WARN Act, separate from and broader than the federal law — it can require 60 days' notice for mass layoffs, plant closings, or relocations from employers not otherwise covered by the federal WARN Act's 100-employee threshold. Final wages are due by the next scheduled payday or three business days after the employee's last day worked, whichever is later. A PEO with Delaware expertise can help businesses navigate the new Paid Leave program, verify LaborFirst registration status, and manage the state's broader WARN coverage. Use the form on this page to connect with PEOs serving Delaware businesses.

Frequently Asked Questions
Does Delaware require paid family and medical leave?
Yes. Delaware's Healthy Delaware Families Act is a state Paid Family and Medical Leave program that began collecting payroll contributions January 1, 2025, and started accepting employee benefit claims January 1, 2026. It applies to employers with 10 or more employees, with full coverage at 25 or more, and pays up to 80% of average weekly wages, capped between $100 and $900 per week.
What is the minimum wage in Delaware in 2026?
Delaware's minimum wage is $15.00 per hour, in effect since January 1, 2025, with no additional increases currently scheduled by the state.
Does Delaware have its own WARN Act?
Yes. The Delaware WARN Act is a state law separate from the federal WARN Act and can apply more broadly — it can require 60 days' notice of a mass layoff, plant closing, or relocation from employers not otherwise covered by the federal law's 100-employee threshold. Delaware issued formal regulations implementing the law that employers should review alongside federal WARN obligations.
When must Delaware employers pay a departing employee's final wages?
Delaware requires final wages to be paid by the next scheduled payday or within three business days of the employee's last day worked, whichever is later. This applies whether the employee quit or was terminated. A PEO can help ensure this deadline is met alongside the state's other final-pay and wage theft protections.
