Overview: LLC Formation in Wilmington, Delaware

Forming a Limited Liability Company (LLC) in Wilmington, Delaware requires compliance with both state-level and city-level requirements. The Delaware Division of Corporations governs state LLC formation under Title 6, Chapter 18 of the Delaware Code, while the City of Wilmington imposes additional local business licensing requirements.

Bottom Line:

Wilmington LLCs must file a state Certificate of Formation ($90), obtain a Delaware business license ($75), secure a Wilmington city business license ($200-$5,000 depending on business type), and pay Delaware's annual LLC tax ($300). Wilmington also requires a head tax of $15 per month for each employee beyond five.

Step 1: Choose Your LLC Name

Delaware LLC Name Requirements

Delaware statute 6 Del. C. ยง 18-102 establishes mandatory naming conventions. Your LLC name must:

  • Include the words "Limited Liability Company" or the abbreviation "L.L.C." or the designation "LLC"
  • Distinguish itself from existing Delaware entities registered with the Secretary of State
  • Avoid restricted words without proper authorization (e.g., "Bank," "Insurance," "University")

Verify Name Availability

Check name availability using the Delaware Division of Corporations Entity Name Search. This free database searches all registered Delaware business entities.

Optional Name Reservation

Reserve your name for 120 days through the Delaware Division of Corporations for a $75 fee. Name reservation guarantees availability while you prepare formation documents but is not required.

Step 2: Appoint a Delaware Registered Agent

Registered Agent Requirement

Delaware law requires every LLC to maintain a registered agent with a physical Delaware street address. The registered agent receives service of process and official state correspondence on behalf of your LLC.

Registered Agent Must:

  • Maintain a physical street address in Delaware (P.O. boxes not permitted)
  • Be available during normal business hours
  • Be either an individual Delaware resident or a business entity authorized to conduct business in Delaware

Registered Agent Options

Option 1:

Act as your own registered agent if you maintain a physical Delaware address

Option 2:

Appoint an individual Delaware resident

Option 3:

Hire a professional registered agent service

Step 3: File the Certificate of Formation with Delaware

Certificate of Formation Requirements

Create your LLC by filing a Certificate of Formation with the Delaware Division of Corporations. According to 6 Del. C. ยง 18-201, the certificate must include:

Required Information:

  • LLC name (complying with naming requirements)
  • Registered agent name and Delaware street address
  • Signature of an authorized person forming the LLC

Filing Methods and Fees

Online Filing (Recommended):

  • Portal: Delaware One Stop
  • Fee: $90
  • Processing: Immediate to several business days
  • Confirmation: Emailed filed certificate

Mail Filing:

Expedited Service & Certified Copies

Contact the Division of Corporations for expedited processing options at additional cost.

Request a certified copy of your Certificate of Formation for $50. Banks and lenders typically require certified copies for opening business accounts.

Step 4: Obtain a Federal Employer Identification Number (EIN)

EIN Requirements for LLCs

The Internal Revenue Service requires most LLCs to obtain an Employer Identification Number. According to IRS guidelines on single-member LLCs, you need an EIN if your LLC:

  • Has employees
  • Files excise tax returns
  • Withholds taxes on non-wage income paid to non-residents
  • Has more than one member (multi-member LLCs are classified as partnerships)

Free Online Application (Recommended):

Apply through the IRS EIN Assistant for immediate issuance. Available Monday through Friday, 7:00 a.m. to 10:00 p.m. Eastern time.

Critical Requirement: Form your LLC with Delaware before applying for an EIN. The IRS requires legal entity formation before issuing an EIN.

Alternative Methods:

  • Fax: Send Form SS-4 to 855-641-6935 (4 business days)
  • Mail: Send Form SS-4 to Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999 (4 weeks)

Important: The IRS never charges for an EIN. Beware of third-party websites that charge fees.

Step 5: Create an LLC Operating Agreement

Operating Agreement Requirement

Delaware mandates that LLCs adopt an operating agreement. Under 6 Del. C. ยง 18-101(9), the operating agreement governs the internal affairs and business conduct of your LLC. Delaware does not require filing the operating agreement with the state.

Operating Agreement Content

The operating agreement should establish:

  • Member ownership percentages and capital contributions
  • Profit and loss distribution methods
  • Management structure (member-managed or manager-managed)
  • Voting rights and procedures
  • Procedures for adding or removing members
  • Dissolution and liquidation procedures
  • Buy-sell provisions

Legal Framework

Delaware statute 6 Del. C. ยง 18-402 provides that unless the operating agreement specifies otherwise, management vests in members proportionally to their profit interests.

Step 6: Register for Delaware State Business License

State Business License Requirement

The Delaware Division of Revenue requires any person or entity conducting business in Delaware to obtain a state business license. This requirement applies whether your LLC operates within Delaware or conducts business from a Delaware entity outside the state.

Registration Process

Register through Delaware One Stop Business Registration, which allows simultaneous registration with:

  • Delaware Division of Revenue
  • Division of Unemployment Insurance (if you have employees)
  • Division of Workers' Compensation (if you have employees)

State Business License Fees

According to the Delaware Division of Revenue:

  • General Services License: $75 per year for first location
  • Additional Locations: $25 per location per year
  • License Expiration: December 31st annually
  • Three-Year Option: Available after first year (three times the annual fee)

Processing Time

Most businesses receive their Delaware business license within one month. Upon completing online registration through One Stop, you can print a temporary license immediately. Permanent licenses arrive by mail within 10 business days.
