More venture-backed companies incorporate in Delaware than in any other state, and cost isn't the reason. Delaware runs the Court of Chancery, a specialized business court with judges instead of juries who rule only on corporate law.
Its LLC Act is written to give "maximum effect" to whatever the members negotiate in their operating agreement, which is why investors and larger structures default here for predictable outcomes, not bargain pricing.
Forming here follows a familiar checklist, but Delaware's flat annual tax and a foreign-qualification trap catch founders who assume Delaware alone settles their compliance picture.
TL;DR
- Why Delaware: the Court of Chancery and a freedom-of-contract statute make outcomes predictable, which is why VCs and larger structures default here, not because it's the cheapest state.
- Step 1, name: confirm your LLC name is distinguishable with the Division of Corporations and reserve it for $75 if you're not ready to file.
- Step 2, registered agent: Delaware has a mature commercial registered-agent industry that most out-of-state and foreign founders use as a matter of course.
- Step 3, Certificate of Formation: file with the Delaware Division of Corporations for $110, with standard processing around a week and paid expedite tiers available.
- Step 4, EIN without an SSN: the IRS online tool requires an SSN or ITIN, so founders without one apply by phone, fax, or mail instead.
- Step 5, Form 5472: a 25%+ foreign-owned single-member LLC must file this every year, even at zero revenue, or risk a $25,000 minimum penalty.
- Step 6, ongoing compliance: Delaware charges a flat $300 Annual Tax due June 1 with no annual report, and generally doesn't tax income a nonresident member earns outside Delaware.
- Common mistakes: assuming Delaware formation erases your home state's own tax and filing obligations is the single costliest misconception founders make.
Why Form Your LLC in Delaware?
Delaware's appeal isn't its price tag. It's legal predictability, built on two features most other states don't have.
- The Court of Chancery: a business-only court staffed by judges, not juries, who specialize in corporate law and have decided disputes over LLC agreements for decades. That track record gives founders and investors a clearer sense of how a dispute would likely play out.
- A freedom-of-contract statute: Delaware's LLC Act instructs courts to give "maximum effect" to the terms members actually negotiate in their operating agreement, rather than overriding them with default state rules.
- Why VCs and larger structures default here: that combination of specialized judges and contract deference is what venture firms and multi-investor structures are typically buying when they require Delaware formation, not a lower cost of doing business.
None of that changes the mechanics of forming the LLC itself. The steps below cover the same ground as any state, with the Delaware-specific facts called out at the point where they apply.
Step 1: Choose and Reserve Your LLC Name
Your LLC's name has to be distinguishable from other entities already on file with the Delaware Division of Corporations, and a few rules apply before you file.
- Include a designator like "LLC" or "Limited Liability Company" in the name.
- Avoid restricted words such as "bank" or "trust," which typically need separate regulatory approval.
- Search for free first through the Division of Corporations' entity name search before filing anything.
- Reserve it for $75 if you're not ready to file yet. Delaware holds a reserved name for 120 days, and you can renew the reservation for another 120-day period for another $75 if you need more time.
This step costs nothing beyond the optional reservation fee, and it works the same whether you're forming from the US or from abroad.
Step 2: Appoint a Registered Agent
Every Delaware LLC needs a registered agent: a person or company with a physical street address in Delaware, available during business hours to receive legal documents and state notices on the LLC's behalf. A PO box doesn't qualify.
- Delaware's registered-agent industry is large and long-established. Because so many companies incorporate here without ever setting foot in the state, using a commercial registered agent is the norm, not a signal of anything unusual about your LLC.
- Most out-of-state and foreign founders use this route by default, since they don't have a Delaware address to list themselves.
- Most services also scan and forward mail, which matters if you're not checking a Delaware mailbox in person.
Skipping a real registered agent for an unlicensed address or a friend's home can put your LLC out of good standing with the state.
Step 3: File Your Certificate of Formation
Delaware calls its formation document a Certificate of Formation, not Articles of Organization, and it's filed with the Delaware Division of Corporations rather than a "Secretary of State" office, which is how Delaware's business filing agency is actually named.
- Filing fee: $110.
- Standard processing: around one week.
- Expedited options: 24-hour service for $50, same-day for $200, two-hour for $500, and one-hour for $1,000, as of publication. Delaware law passed in May 2026 (HB 400) authorized higher expedite fee ceilings starting August 1, 2026, so confirm current pricing directly with the Division of Corporations before filing.
- No newspaper publication requirement. Unlike a handful of other states, Delaware doesn't require you to publish notice of your new LLC in a local paper.
Once the Division of Corporations approves your filing, your LLC legally exists, and the tax and compliance clock covered in the next few steps starts running.
Step 4: Get an EIN, Even Without an SSN
An Employer Identification Number (EIN) is what the IRS uses to identify your LLC for tax purposes, and you'll need one to open a US bank account or file taxes. It's free directly from the IRS.
Founders with a Social Security Number or an Individual Taxpayer Identification Number (ITIN) can typically apply online and get an EIN in minutes. Without either one, you'll use Form SS-4 instead.
| Method | Who can use it | Typical speed |
|---|---|---|
| Online EIN application | SSN or ITIN holders | Minutes |
| Form SS-4 (phone, fax, or mail) | Founders without an SSN or ITIN | Same-day to several weeks |
The manual route's wait mostly depends on IRS volume and how completely the form was filled out, since a rejected submission means starting the wait over.
Step 5: File Form 5472 if the LLC Is Foreign-Owned
If your single-member LLC is 25% or more foreign-owned, the IRS requires an annual Form 5472 filing, even at zero revenue. This applies regardless of which state formed the LLC, including Delaware.
- Filed with a pro forma Form 1120, a placeholder corporate return required alongside the 5472, even though the LLC itself typically owes no separate corporate tax.
- Reports transactions between the LLC and its foreign owner, such as capital contributions or payments for services.
- Applies even when dormant. A low-activity LLC is not exempt just because it hasn't generated revenue yet.
The IRS's stated minimum penalty for a late or missing Form 5472 is $25,000, per form, per year, whether or not the LLC made a dollar.
Treat this filing as non-negotiable from the day your Delaware LLC exists.
Step 6: Handle Delaware's Ongoing Compliance
Delaware's ongoing obligations look simple on paper, and mostly are, but they're not the whole picture if you operate anywhere else.
- Flat $300 Annual Tax, due June 1 every year. Delaware calls this the Annual (Franchise) Tax for LLCs, and unlike many states, it doesn't scale with revenue or assets. It's the same $300 whether your LLC made nothing or millions.
- No annual report required for LLCs. Delaware corporations file an annual report alongside their franchise tax; LLCs just pay the flat tax with no separate report.
- Missing the deadline costs more than you'd expect. A late payment adds a $200 penalty plus 1.5% monthly interest on the unpaid balance.
- Delaware's personal income tax generally doesn't reach out-of-state LLC income. Delaware taxes individual income on a graduated scale from 2.2% to 6.6%, but a nonresident member with no Delaware-source income and no physical presence in the state typically owes no Delaware personal income tax on the LLC's earnings. Delaware also has no state sales tax.
An operating agreement isn't filed with the state, but it's still worth drafting. It documents how the LLC is owned and run, which matters if a bank, the IRS, or a court ever needs to confirm the LLC operates as a genuinely separate entity from its owner.
None of this replaces your obligations in the state where you actually operate. Forming in Delaware doesn't remove the tax nexus or filing requirements of the state where your business has an office, employees, or a physical presence. That gap is covered in the mistakes below.
Common Mistakes to Avoid
- Assuming Delaware formation erases your operating state's obligations: if your LLC has an office, employees, or a physical presence in a different state, you generally need to foreign-qualify there too, filing a Certificate of Registration of Foreign LLC for roughly $200. That leaves you managing two states' compliance stacks: Delaware's $300 tax plus your operating state's own annual report or franchise tax.
- Treating the EIN as the finish line: for a foreign-owned LLC, the EIN is closer to the starting gun on an annual Form 5472 filing than the end of the process.
- Skipping Form 5472 because there's no revenue yet: the filing requirement doesn't care whether the LLC has made money.
- Using an unlicensed address as your registered agent: it can put the LLC out of good standing and exposes a personal address on public record.
- Missing the June 1 franchise tax deadline: the $200 penalty plus monthly interest adds up faster than founders expect for what's otherwise a flat, predictable fee.

FAQ
Do I still owe taxes in my home state if I form my LLC in Delaware?
Generally, yes. Forming in Delaware only satisfies Delaware's own requirements, and it doesn't remove the tax nexus or filing obligations of the state where your business actually operates.
If you have an office, employees, or a physical presence elsewhere, that state can typically still require its own tax filings and often a separate foreign-qualification registration. Consult a tax professional to confirm how this applies to your situation.
What happens if I miss Delaware's $300 annual franchise tax deadline?
Delaware adds a $200 late penalty plus 1.5% interest per month on the unpaid balance starting after the June 1 due date. The tax applies to every Delaware LLC regardless of revenue.
Continued nonpayment can eventually affect the LLC's good standing with the state. There's no separate annual report to file alongside it, just the flat tax itself.
Can I act as my own registered agent for a Delaware LLC?
Only if you have a physical street address in Delaware and can be available during business hours to receive legal documents, which rules out most non-Delaware and international founders.
That's why Delaware's commercial registered-agent industry is so widely used. It's the standard solution for anyone forming from outside the state, not a workaround. A PO box never qualifies as a registered agent address.
