Delaware Payroll Compliance Guide 2026: Taxes, Wages & Labor Laws

Delaware is often overshadowed as a business registration state — the Delaware LLC and C-corp are famous — but running actual payroll in Delaware requires its own compliance setup. The state has a graduated income tax that tops out at 6.6%, a SUI wage base of $10,500, and a minimum wage that hit the $15.00 milestone in 2025. Delaware also passed paid family leave legislation in 2022 that is phasing in contributions and benefits; employers with operations in Delaware should verify their current obligations with the Delaware Department of Labor.

The state's compliance landscape is relatively stable compared to neighbors like Maryland or New Jersey, but the income tax brackets require accurate withholding tables, and the monthly pay frequency minimum is a baseline that some employers miss.

Delaware Payroll at a Glance

State Income Tax Withholding

Delaware's income tax uses six brackets. The structure makes Delaware a moderate-tax state — the 0% bracket at the bottom and the 6.6% ceiling at the top.

Most full-time employees earning a standard wage will have income taxed primarily at the 5.55% and 6.6% rates. The 0% bracket only shelters the first $2,000 of taxable income.

Employee Withholding: Delaware Form W-4

Delaware uses the Delaware Employee's Withholding Allowance Certificate (Form W-4) for state withholding elections. It functions similarly to the federal W-4. If an employee doesn't provide one, withhold at the zero-allowance rate. Withholding tables are published annually by the Delaware Division of Revenue.

Employers remit Delaware income tax withholding to the Delaware Division of Revenue online through the Delaware Taxpayer Portal (revenue.delaware.gov). Filing frequency depends on withholding volume — quarterly for small employers, monthly for larger ones. Year-end W-2s and reconciliation filings are due January 31.

State Unemployment Insurance (SUI)

Delaware SUI is administered by the Delaware Department of Labor, Division of Unemployment Insurance. The $10,500 taxable wage base is above the federal FUTA base but below the national median.

SUI Rates for 2026

• New employer rate: 1.8%
• Experienced employer range: 0.3% to 8.2%
• Taxable wage base: $10,500 per employee per year
• Maximum annual cost per employee (new employer at 1.8%): $189
• Maximum possible cost per employee (at 8.2%): $861

SUI returns are filed quarterly. Deadlines follow the standard schedule: April 30, July 31, October 31, January 31.

Minimum Wage

Delaware's minimum wage reached $15.00 per hour in 2025, completing the phased increase schedule enacted by the Delaware General Assembly. At $15.00, Delaware is at parity with states like New Jersey and Massachusetts. No additional automatic annual increases are currently set in statute, though the legislature may revisit the rate.

Tipped Employees

Delaware allows a tip credit. Tipped employees must receive at least $2.23 per hour in direct wages, with tips making up the difference to $15.00. If tips don't cover the gap, the employer must pay the shortfall. Tip credit applies only to employees who customarily and regularly receive tips in the course of employment.

Youth Subminimum Wage

Delaware permits a training wage of $8.75 per hour for employees under 18 during their first 90 days of employment. After 90 days or upon turning 18, the full minimum wage applies.

Overtime

Delaware follows FLSA: non-exempt employees earn 1.5x their regular rate for hours over 40 in a workweek. No additional state overtime rules beyond FLSA.

Pay Frequency Requirements

Delaware law requires wages to be paid at least monthly. Most Delaware employers pay more frequently — bi-weekly is standard in most industries — and that satisfies the monthly minimum. True monthly payroll (one check per month) is the legal floor but is uncommon in practice.

Delaware also requires employers to establish and maintain regular pay periods. You can't pay on an irregular schedule. Once you set a pay frequency (weekly, bi-weekly, semi-monthly, or monthly), stick to it or formally change it with proper notice to employees.

Final Paycheck Rules

Delaware requires final wages to be paid on the next regular payday following the separation. This applies to both voluntary resignations and involuntary terminations. No requirement to pay on the date of discharge.

Accrued Leave at Termination

Delaware does not mandate vacation payout at termination by statute. Your written policy controls. If your employee handbook promises vacation payout, it's enforceable. A "use it or lose it" policy must be clearly communicated. Delaware courts generally enforce written policies that were known to the employee.

Federal Payroll Taxes

All Delaware employers also owe federal payroll taxes:

• Social Security: 6.2% employer + 6.2% employee on wages up to $176,100
• Medicare: 1.45% employer + 1.45% employee on all wages; 0.9% Additional Medicare Tax on employee wages over $200,000
• FUTA: 6.0% on first $7,000, effective 0.6% with state UI credit
• Federal income tax withholding: Per each employee's W-4

Registering as a New Employer in Delaware

Two primary registrations are required before running Delaware payroll:

• DDOL registration: Register with the Delaware Department of Labor, Division of Unemployment Insurance for your SUI account at ui.delawareworks.com.

If your business is subject to the Healthy Delaware Families Act PFML program, register with the DDOL for that program as well. Confirm your employer size relative to the program thresholds.
