Updated August 6, 2026 — registration steps, deadlines, and rates below were verified against official Delaware agency sources in August 2026. Confirm current figures with the agencies before filing.
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.
Both registrations start at Delaware One Stop (onestop.delaware.gov); withholding registration is free, and the UC-1 unemployment form is due within 20 days of first hiring.
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 employers file withholding monthly by default and pay a 1.0% new-employer UI rate on the first $14,500 of wages per employee (as of 2026).
Report every new hire to the Delaware State Directory of New Hires within 20 days of the start date.
Incorporated in Delaware? That alone doesn't trigger payroll taxes
More than a million businesses are incorporated in Delaware, and most of them will never owe the state a 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 requires withholding registration from businesses maintaining an office or conducting business in the state while paying wages subject to withholding. No workers in Delaware 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. Delaware's unemployment law reaches broadly once that happens. Standard employers become liable when they employ one or more individuals for any portion of a day, and Delaware has no reciprocity agreements with any state, so out-of-state companies with Delaware workers must still register and withhold. 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 employers with 10 or more Delaware employees).
New-hire reporting — handled by the Division of Child Support Services, which runs 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) and covers business licensing.
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 within 20 days of their start dates.
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 (July 1 through June 30). As of August 2026, annual withholding of $6,020 or less puts you on quarterly filing, $6,020.01 to $33,460 means monthly, and above $33,460 requires eighth-monthly deposits. Monthly returns are due by the 15th of the following month. 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 by the end of the month following each quarter. As of 2026, the new-employer rate is 1.0% on a taxable wage base of $14,500 per employee.
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 contributions only; 25 or more triggers full coverage (parental, medical, and family caregiving). The program is funded by less than 1% of wages, and employers may deduct up to half from employees. Quarterly Hours & Wage Reports and payments run through LaborFirst.
New-hire reporting. Every new hire must be reported within 20 days, including the employee's name, address, and SSN plus your company name, address, and FEIN.
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, though they may opt in voluntarily. At 10 to 24 employees, only parental-leave contributions are required; at 25 or more, all three lines of coverage apply. Count only employees working in Delaware, not your total headcount.
