Incorporating in Delaware does not create payroll tax obligations. You register for Delaware payroll taxes only when someone actually performs work in the state.
Employers with Delaware workers need two core accounts: a withholding account from the Division of Revenue and an unemployment insurance account from the Division of Unemployment Insurance.
Withholding registration happens on Delaware One Stop (onestop.delaware.gov) and is free; the UC-1 unemployment form is due within 20 days of your first day of business.
Delaware Paid Leave is now live: payroll contributions began January 1, 2025, and employees began filing claims January 1, 2026. Employers with 10+ Delaware employees must register in Delaware LaborFirst.
New withholding agents file monthly until the next lookback period, and the Division of Unemployment Insurance assigns new employers a new-employer UI rate.
Report every new hire to the Delaware State Directory of New Hires.
How do you register for payroll taxes in Delaware?
Register on Delaware One Stop for a free withholding account with the Division of Revenue, file Form UC-1 with the Division of Unemployment Insurance within 20 days of your first day of business, and enroll in Delaware Paid Leave through LaborFirst once you have 10 or more Delaware employees. You only need these accounts if someone actually works in Delaware; incorporating there does not create payroll tax obligations.
Your corporate obligations to the Delaware Division of Corporations are separate and apply no matter where your team works: corporations file a $50 annual report and pay franchise tax (minimum $175) by March 1, and LLCs pay a flat $400 annual tax by June 1, per the Division's figures as of October 17, 2026.
Delaware employer payroll tax figures, as of October 2026
A Delaware C-corp runs payroll under the rules of each state where its employees work, not where it is incorporated, plus the federal rules that apply everywhere. In 2026 that means federal Social Security, Medicare and FUTA for every employee, and Delaware unemployment insurance, withholding and Paid Leave once someone works in Delaware. The table lists each figure with its official source and the date collected.
The federal rows apply to every U.S. employer. The Delaware rows apply once someone works in Delaware, as covered below.

Incorporated in Delaware? That alone doesn't trigger payroll taxes
Incorporating in Delaware does not, by itself, create a Delaware payroll tax filing. Payroll tax registration follows where your employees physically work, not where your certificate of incorporation was filed. A Delaware C-corp with a founding team in Austin and engineers in New York registers for employer payroll taxes in Texas and New York, not Delaware.
The confusion is understandable: your registered agent, franchise tax, and annual report all live in Delaware, so it feels like payroll should too. It doesn't. Delaware's Division of Revenue says withholding is only required in the duty-assigned state, meaning the state where the employee's work is assigned. No workers in Delaware generally means no Delaware withholding account, no Delaware unemployment insurance account, and no Delaware Paid Leave obligations.
When Delaware registration is required
You need Delaware payroll accounts when someone actually works there: you hire a Delaware-based remote employee, open an office in Wilmington, or an existing employee relocates to the state. The Department of Labor defines an employer as an individual or employing unit that employs one or more individuals for some portion of a day. Delaware also has no reciprocity agreement with any state, so withholding follows where the work is assigned, not where the employee lives. If this is your first state registration anywhere, it helps to understand the mechanics of running payroll for the first time before you start opening accounts.
The accounts you need and who issues them
Delaware splits employer registration across agencies:
Withholding account: issued by the Division of Revenue. This is the account you use to remit state income tax withheld from employee paychecks.
Unemployment insurance (UI) account: issued by the Division of Unemployment Insurance within the Department of Labor, which assigns your state UI tax number and rate.
Delaware Paid Leave account: administered through Delaware LaborFirst, the Department of Labor's system for the state's paid family and medical leave program (required for most employers with 10 or more Delaware employees).
New-hire reporting: new hires are reported to the Delaware State Directory of New Hires.
How to register, step by step
Get a federal EIN from the IRS if you don't have one; every Delaware registration asks for it.
Create an account at Delaware One Stop, the state's registration and licensing portal, and complete the Combined Registration Application (CRA). This registers you with the Division of Revenue for withholding (there is no cost to open a withholding account); One Stop is also the state's portal for business license registration.
Register for unemployment insurance. New employers complete Form UC-1, the "Report to Determine Liability," due no later than 20 days after the first day of business. The Division of Unemployment Insurance then issues your UI account number and rate.
If you have 10 or more Delaware employees, register in Delaware LaborFirst for Delaware Paid Leave, providing your legal business name, FEIN, addresses, and business start date.
Report your first hires to the Delaware State Directory of New Hires.
Have your EIN, entity details, Delaware business start date, and officer information ready before you begin. Once the accounts exist, most payroll software files these returns and deposits for you.
Ongoing obligations after you register
Withholding deposits. New withholding agents file monthly until the next lookback period, after which the Division of Revenue sets your filing frequency. The annual reconciliation, with copies of employee W-2s, is due by the last day of January.
Unemployment insurance. Quarterly wage reports (Forms UC-8 and UC-8A) and payments are due within one month after each quarter ends. New employers pay the new-employer rate until they qualify for an experience-based rate. For 2026 that is 1.0% on the first $14,500 of each employee's wages, per the Division of Unemployment Insurance as of October 22, 2026.
Delaware Paid Leave. Contributions began January 1, 2025, and employees began submitting benefit claims January 1, 2026, so this program is fully live. Employers with 10 to 24 Delaware employees owe parental-leave coverage only; 25 or more triggers full coverage. The program is funded by less than 1% of an employee's weekly wages, and employers may require employees to contribute up to half the cost. Quarterly Hours & Wage Reports and payments run through LaborFirst.
New-hire reporting. Report every new hire to the Delaware State Directory of New Hires.
Deadlines across three agencies add up fast, which is why most startups let payroll software handle the filings once registration is complete.
FAQ
Do I need Delaware payroll accounts if my startup is incorporated there but everyone works remotely in other states?
No. Payroll registration follows work location. Register in the states where your employees physically work, and keep handling Delaware franchise tax and annual reports separately as corporate obligations. You only open Delaware payroll accounts when someone actually performs work in Delaware.
How long does Delaware payroll registration take?
Registration through Delaware One Stop is an online process, and the withholding account is free to open. Budget time for the UC-1 unemployment liability determination and, if you have 10 or more Delaware employees, LaborFirst enrollment. Start before your first Delaware payday, since the UC-1 is due within 20 days of your first day of business.
Does Delaware Paid Leave apply to a startup with a handful of Delaware employees?
Employers with 9 or fewer Delaware employees are exempt. At 10 to 24 employees, only parental-leave contributions are required; at 25 or more, full coverage applies. Count only employees working in Delaware, not your total headcount.
What is Delaware's new-employer unemployment insurance rate?
For 2026, Delaware's new-employer rate is 1.0%, applied to the first $14,500 of each employee's wages, per the Delaware Department of Labor as of October 22, 2026. That costs up to $145 per employee for the year (1.0% of the first $14,500, arithmetic on the sourced rates). Once you qualify for an experience-based rate, Delaware's 2026 table runs from 0.3% to 5.4%.
How soon must a Delaware employer report a new hire?
Within 20 days of the employee's start date, to the Delaware State Directory of New Hires. Form UC-1 has its own 20-day clock, which starts on your first day of business rather than on each hire. Track both deadlines separately.
