Delaware LLC formation requirements
Forming a Delaware LLC means meeting the statutory requirements in Delaware's Limited Liability Company Act, Title 6, Chapter 18 of the Delaware Code. Skip one, and the Division of Corporations can reject your filing; skip an ongoing obligation later, and your LLC loses good standing and, eventually, its Certificate of Formation.
These requirements cut across:
Naming requirements
Registered agent requirements
Certificate of Formation filing
Operating agreement considerations
Ongoing compliance obligations
1. Name requirements
Your Delaware LLC name must include "Limited Liability Company," "L.L.C.," or "LLC" under § 18-102(1). Without that suffix the certificate fails before anyone reads the rest of the form.
Next comes uniqueness. Under § 18-102(3), the name must "distinguish it upon the records in the office of the Secretary of State" from any corporation, partnership, limited partnership, statutory trust, or LLC already on file in Delaware, including registered foreign entities. Check availability with the Division of Corporations before you file, and check domain availability too.
You can reserve the name for 120 days for $75 through the Division's name reservation page, and the Secretary of State holds it "for the exclusive use of the applicant" (§ 18-103(b)). The Division of Revenue charges $25 for a trade name license if you operate under another name.
2. Registered agent requirements
Every Delaware LLC must maintain a registered office and a registered agent in the state (§ 18-104(a)(1)). The office must be a Delaware address, though it "need not be a place of its business." Your agent receives service of process on the LLC's behalf, so registered agent services for Delaware LLCs need to be in place from day one.
In practice, owners either list a Delaware resident who will be at the address during business hours, the category the Act spells out for foreign LLCs at § 18-904(b)(2), or hire a commercial registered agent service. Registered agents serving more than 50 entities must maintain a Delaware business license and have a Delaware location generally open or staffed during normal business hours (§ 18-104(f)).
Losing your agent starts a short clock. A resigning agent must give the LLC written notice at least 30 days before filing a certificate of resignation, and § 18-104(d) provides that if the LLC "fails to obtain and designate a new registered agent prior to the expiration of the period of 30 days after the filing by the registered agent of the certificate of resignation, the certificate of formation of such limited liability company shall be canceled." After cancellation, if ordinary service under § 18-105(a) cannot be effected with due diligence, service of process may be made on the Secretary of State under § 18-105(b).
3. Certificate of Formation requirements
Filing a Certificate of Formation brings your Delaware LLC into legal existence, and the statute asks for less than most founders expect: two required items under § 18-201(a), everything else optional. A certificate that names the agent and the office address complies even if those items are not labeled as such (§ 18-201(e)).
Your LLC's legal name (§ 18-201(a)(1)), carrying the suffix § 18-102(1) requires
The registered office address and the agent's name and address (§ 18-201(a)(2))
Any other matters the members choose to include under § 18-201(a)(3); many filers add a management structure designation (member-managed vs. manager-managed) or a principal business address
Signature of one or more "authorized persons," the statutory term rather than "organizer" (§ 18-201(a))
The commonly quoted $110 is two charges: $70 under § 18-1105(a)(3) plus a $40 courthouse municipality fee under § 18-206(e). Delaware Code Title 6, § 18-1105 identifies the $70 certificate-of-formation filing fee, and § 18-206 identifies the $40 municipal fee, and no official source labels $110 as a single filing fee; this Delaware LLC formation cost breakdown covers the rest of year one.
File online through eCorp Business Services or by mail to the Division of Corporations in Dover, per its How to Form page. The Division publishes no fixed timeline; its FAQ page says only that "processing time for regular (non-expedited) work varies based upon the volume of items received," so treat any "10 business days" figure as a practitioner estimate.
Expedited services run $50.00 to $100.00 next-day (submit by 7:00 pm), $100.00 to $200.00 same-day (by 2:00 pm), $500.00 two-hour, and $1,000.00 one-hour (by 9:00 pm EST/EDT).
4. Operating agreement requirements
Delaware law doesn't require a written operating agreement, but experienced owners never skip one. A "limited liability company agreement" can be "written, oral or implied," and members and managers are bound whether or not they sign (§ 18-101(9)). Without written terms, an implied agreement nobody documented may govern your dispute.
The agreement sets ownership, decision-making authority, and profit distribution. You don't file it with the Division of Corporations.
A solid Delaware operating agreement typically covers:
Member names and ownership percentages
Capital contributions and voting rights
Management structure (member-managed vs. manager-managed)
Transfers and admission of new members
Allocation of profits, losses, and distributions
Meeting requirements and record-keeping expectations
Dispute-resolution methods and buyout provisions
Events that trigger dissolution and winding-up process
Creating these provisions upfront costs far less than resolving ambiguous agreements through court battles later.
State policy gives "maximum effect to the principle of freedom of contract" (§ 18-1101(b)), and an agreement may expand, restrict, or eliminate fiduciary duties, though it "may not eliminate the implied contractual covenant of good faith and fair dealing" (§ 18-1101(c)). In the words of the Delaware Court of Chancery, "An LLC is primarily a creature of contract, and the parties have wide contractual freedom to structure the company as they see fit."
5. Initial and ongoing compliance requirements
Once Delaware approves the Certificate of Formation, federal and state obligations start, and your registered agent details must stay current with the Division.
A multi-member LLC needs an EIN; the IRS EIN application is free ("You never have to pay a fee for an EIN") and issues one online immediately. A single-member LLC treated as a disregarded entity needs one only if it has employees, owes excise tax, opens a business bank account, or state tax law requires one.
Conducting a trade or business in Delaware requires a license from the Division of Revenue, "generally $75.00 for a first location," with a separate license for each activity (license requirements). Most expire December 31 (business license FAQs).
You "can open a business bank account once you've gotten your federal EIN," per the Small Business Administration.
Every Delaware LLC owes a flat $300 annual tax (§ 18-1107(b)) due June 1 (§ 18-1107(c)); this Delaware franchise tax for LLCs guide covers payment. The Division's tax FAQ confirms $300 and states "There is no requirement to file an Annual Report," though one Division page, the LLC/LP/GP tax instructions, still lists $400.
Consequences of non-compliance
Miss the June 1 tax deadline or let your registered agent lapse, and Delaware's LLC Act escalates in defined steps. The Act's term for termination of the certificate of formation is "cancellation"; "dissolution" is the separate event that triggers winding up under Subchapter VIII.
Consequences include:
Franchise tax penalties: An LLC that misses June 1 owes a $200 penalty (§ 18-1107(e)), and Delaware law provides that unpaid LLC annual tax bears interest at 1.5% for each month or portion of a month until fully paid.
Loss of good standing: An LLC that fails to pay the annual tax "shall cease to be in good standing" (§ 18-1107(h)), after which the Secretary of State refuses most filings, issues no certificate of good standing (§ 18-1107(k)), and the LLC cannot sue in a Delaware court until restored (§ 18-1107(l)). Paying the back tax, penalty, and interest restores standing with no revival filing (§ 18-1107(i)).
Cancellation of the Certificate of Formation: Delaware cancels the certificate when the annual tax goes unpaid "for a period of 3 years from the date it is due," effective on the third anniversary; certificates canceled on June 1 are listed with the Secretary of State and published on or before October 31 (§ 18-1108). Failing to replace a resigned agent cancels it at the 30-day mark instead. Filing a certificate of revival with all back taxes, penalties, interest, and the § 18-1105(a)(3) fee brings the LLC back (§ 18-1109).
Foreign qualification complications: The SBA notes that "Many states also require a Certificate of Good Standing from your state of formation" before approving a foreign registration. With that certificate blocked while an LLC sits out of good standing (§ 18-1107(k)), Delaware foreign qualification for expansion stalls in most states that ask for one until "all back taxes and filing fees" are paid (renewal page).
Ensure Delaware LLC compliance with Discern
Discern covers the Secretary of State requirements above: registered agent, formation filing, and the Delaware franchise tax. Its registered agent service gives your LLC a physical Delaware office and a person present during business hours, so a resignation notice does not sit unread against a 30-day clock.
For funds, technology companies, and healthcare groups running many Delaware entities, Discern tracks good standing in one dashboard, auto-creates and files annual reports across the jurisdictions where those entities are registered, and flags the good-standing gaps that block a foreign registration. For organizations managing multiple registrations, centralized automation can reduce manual tracking and filing work.

Frequently asked questions
These answers cover the Delaware LLC requirements that generate the most follow-up questions from multi-entity teams.
How much does it cost to form a Delaware LLC?
The $110 most sources quote is a $70 statutory fee (§ 18-1105(a)(3)) plus the $40 courthouse municipality fee (§ 18-206(e)). Reserving a name adds $75 for 120 days, and expedited turnaround runs $50 to $1,000.
Does a Delaware LLC have to file an annual report?
No. The only recurring state obligation is the flat $300 annual tax due June 1 (§ 18-1107(b), (c)); annual reports belong to Delaware corporations.
What happens if my registered agent resigns?
The agent owes you 30 days' written notice before filing, and you get 30 days from that filing to appoint a replacement. Miss it and your Certificate of Formation is canceled (§ 18-104(d)), leaving revival under § 18-1109 as the only way back.
