How to Start an LLC in Delaware in 2026: 8 Steps

How do you start an LLC in Delaware?

You start a Delaware LLC in eight steps: clear a name, appoint a Delaware registered agent, file a Certificate of Formation for $110, adopt an operating agreement, get an EIN, open a business bank account, pay the $400 annual tax by June 1 each year, and register in any other state where you operate. Delaware LLCs file no annual report, according to the Delaware Division of Corporations fee schedule revised August 1, 2026 (figures as of October 17, 2026).

If you want the formation handled for you, Rho Incorporation forms LLCs for $349 all in, state filing fee included. When you incorporate a Delaware C-corp with Rho for $400, your Rho business account application opens in the same flow, subject to approval.

Best for: founders forming a Delaware C-corp who want their company formed and a business account opened in the same flow, subject to approval. We assess formation options on price, what's included, and whether a business account can open in the same flow as formation.

What a Delaware LLC actually is, and why founders choose it

A limited liability company is a hybrid legal structure: it gives its owners, called members, the personal liability protection of a corporation while letting profits and losses pass through to their personal tax returns like a partnership or sole proprietorship.

Delaware did not invent the LLC (Wyoming did), but Delaware's version, governed by the Delaware Limited Liability Company Act, has become the default choice for founders who form outside their home state, for a few concrete reasons rather than just reputation.

First, Delaware's Court of Chancery is a specialized business court with no juries and judges who spend their careers on corporate and LLC disputes, which produces faster, more predictable rulings than a generalist state court would.

Second, Delaware's LLC Act gives members unusually broad freedom to write their own rules in the operating agreement, and Delaware courts have a long history of enforcing those private agreements as written.

Third, Delaware does not require an LLC to disclose its members or managers on the public Certificate of Formation, which gives owners a level of privacy many states do not offer.

There is also a tax angle worth understanding correctly rather than repeating the shorthand version. Delaware does not tax the income an LLC earns outside Delaware when that income belongs to a member who is not a Delaware resident, which is why you will see Delaware described as having no state income tax for out-of-state owners.

Your home state almost certainly still taxes that same income, and step 8 of this guide covers when you owe your home state a second registration on top of Delaware's own filing.

Treat "no Delaware income tax" as one factor among several, not a reason by itself to form there.

None of this requires you to live in Delaware, visit Delaware, or hold any particular citizenship. Many Delaware LLC owners never set foot in the state, using a registered agent as their only physical connection to it.

What Delaware does require is the eight steps below, done in order.

Delaware series LLCs: a variation worth knowing about

Delaware also permits a series LLC, a single LLC that creates internal, walled-off "series," each with its own assets, liabilities, and members, protected from the debts of the other series inside the same LLC.

Series LLCs show up most often in real estate (a separate series for each property, so a lawsuit over one property cannot reach the others) and in fund structures (a separate series per investment).

Most founders forming a single operating business do not need one. The added complexity in accounting, banking, and legal documentation only pays off when you actually have multiple, genuinely separable pools of assets or liability.

If that describes your situation, get a lawyer involved before filing. The internal liability shielding only holds up if the series are administered correctly and kept truly separate in practice, not just on paper.

LLC vs. C corp vs. S corp vs. sole proprietorship

Before you file anything, it helps to know what you are actually choosing between. Delaware lets you form several kinds of entities, and this guide is specifically about forming a limited liability company.

Here is how an LLC compares to the three structures founders ask about most, side by side.

The short version: an LLC is the flexible, low-maintenance option for a business that plans to keep its profits, or split them among a small group of owners, rather than raise institutional money.

A sole proprietorship costs nothing to start, but it leaves your personal assets exposed to business debts and lawsuits, which is the main reason many founders outgrow it within their first year or two of real revenue.

An S corporation is not a separate entity you form at the state level. It is a tax election you file on top of an LLC or a corporation, using IRS Form 2553.

Electing S corp status can lower self-employment tax for a profitable, owner-operated business, but it adds payroll requirements, a reasonable-compensation test, a 100-shareholder cap, and a single class of stock, which rules out most venture rounds.

If your Delaware LLC is already profitable and you are weighing the S corp election, our guide on whether your LLC counts as an S corp or a C corp walks through the mechanics.

A Delaware C corporation becomes the default choice once venture capital enters the picture. Venture funds are structured to buy preferred stock, and many cannot legally invest in a pass-through LLC at all.

A C corp also supports employee stock option pools and Qualified Small Business Stock (QSBS), a federal tax benefit that can shelter a meaningful share of gain on a future sale. The tradeoff is double taxation: the corporation pays tax on its profits, and shareholders pay tax again on any dividends.

Our C corp vs. S corp comparison and our Delaware C corp guide cover that tradeoff in full, and our companion Delaware LLC formation guide goes deeper on the LLC-versus-C-corp decision itself if you are still weighing which entity to file.

If a Delaware C corp turns out to be the better fit for your business, **Rho Incorporation** forms Delaware C-corps for $400, with every formation document reviewed by a licensed attorney. Your EIN application is filed for you, 83(b) election support is included, registered agent service is covered for the first year, and your Rho business account application can open in the same flow, subject to approval.

If you are comparing formation providers generally rather than deciding between entity types, our breakdown of incorporation service costs compares the cost of each option.

What you need before you start

Gather these before you open the first form, and the eight steps below go much faster:

• A cleared LLC name that includes an LLC designator and has passed a search on icis.corp.delaware.gov.

• A registered agent with a physical Delaware street address, lined up and confirmed before you file, since the certificate requires their name and address.

• A payment method for the $110 state filing fee, plus any expedite fee you decide to pay.

• The responsible party's SSN or ITIN if you have one, so you can apply for an EIN online once the LLC is approved; otherwise, budget extra time for Form SS-4 by fax or mail.

• A plan for your operating agreement, even a simple single-member one, ideally drafted or reviewed before the LLC's first transaction.

• Clarity on where you actually operate, so you know at filing time whether step 8's foreign-qualification requirement will apply to you.

The 8 steps to start a Delaware LLC

Each step below builds on the one before it. Do them out of order and you will find yourself stuck: you cannot open a bank account without an EIN, you cannot get an EIN in most cases without an approved Certificate of Formation, and you cannot file the certificate without a registered agent already lined up.

Follow the sequence and there is nothing to redo.

1. Search your LLC name

Start with the free entity name search on the Delaware Division of Corporations website. Your name must be distinguishable on the record from every entity already on file in Delaware, and it must include a designator such as "LLC," "L.L.C.," or "Limited Liability Company." Distinguishable is a narrower bar than many founders expect.

Search a few variations before you settle on one, since near-matches get rejected at the filing stage rather than at the search stage, which costs you time.

It helps to search the exact name, a version without your designator, and a version with common words stripped out, so you can see what the state's matching logic actually treats as equivalent.

If the name you want is available but you are not ready to file yet, for example because you are still finalizing an operating agreement or waiting on a co-founder, Delaware lets you reserve it for a separate fee.

Many founders skip the reservation entirely and file the certificate of formation as soon as they confirm the name is open.

A name reservation also does not grant you a domain name or a trademark, so check availability on both fronts at the same time if the brand name matters as much as the legal name.

For context on how the state's filing office is organized and what else it handles beyond name searches, see our overview of the Delaware Division of Corporations.

2. Appoint a Delaware registered agent

Every Delaware LLC must continuously maintain a registered agent: a person or company with a physical street address in Delaware, available during business hours, to accept service of process and official state mail on the LLC's behalf. A P.O. box does not qualify. If your LLC is ever sued, the registered agent is where the lawsuit paperwork legally lands, so this is not a role to leave unmanaged.

If you personally live in Delaware, you can serve as your own agent at no extra cost. Almost everyone else forming a Delaware LLC from another state hires a commercial registered agent.

Registered agent pricing is set by each individual provider, not by the State of Delaware, and it varies with what the provider bundles, such as compliance reminders or mail scanning, so it is worth comparing more than one quote.

Choose your agent before you file, because the certificate of formation requires the agent's name and Delaware address as one of its required fields.

Switching agents later is possible but means filing a change-of-agent amendment with the state, so getting this right up front saves a second filing. Look for a provider with a track record of forwarding notices promptly.

A missed tax notice or lawsuit notification because an agent sat on mail is a preventable, expensive mistake.

Our Delaware registered agent guide covers how to evaluate providers on more than price, and what the process looks like if you ever need to replace one after formation.

3. File the certificate of formation

The certificate of formation is the document that legally creates your LLC. It is short by design: your LLC's exact name, your registered agent's name and Delaware address, and an authorized signature.

Delaware does not ask who owns the LLC or how profits are split on this form, which is one reason the state is popular with founders who value privacy; ownership and economics live in your operating agreement instead, a private document you do not file with the state.

You can file online through the Division of Corporations' document upload service, by mail, or through a formation service or registered agent that prepares and submits the document for you, for a service fee on top of the state's own charge.

The table below shows the current LLC filing fees from the Delaware Division of Corporations fee schedule, revised August 1, 2026 (figures as of October 17, 2026).

The state filing fee itself does not change based on how fast you need the entity; expedited service is a separate, additive charge for how quickly Delaware's office processes the document once it is submitted.

Many founders do not need to pay for speed. The expedited tiers exist mainly for situations with a hard external deadline, such as a contract's formation clause or a financing close, rather than for everyday convenience.

4. Adopt an operating agreement

Delaware does not require you to file an operating agreement with the state, and that surprises a lot of first-time founders into skipping it entirely.

Skip it and you are running the LLC on Delaware's generic statutory default rules, which were not written with your specific business in mind and rarely match what the members actually intended.

You should have a real operating agreement in place before the LLC signs its first contract, opens its first bank account, or takes its first dollar.

The agreement sets ownership percentages, capital contributions, voting rights, how profits and losses get allocated, what happens if a member wants to leave, dies, or becomes incapacitated, and how disputes between members get resolved.

Delaware law gives LLC members unusually broad freedom of contract here; courts will generally enforce whatever the members agreed to in writing, even terms that would be unusual for a corporation.

That freedom is a feature, but it also means a poorly drafted agreement, or a generic template downloaded without review, can lock in terms nobody actually wants once a real dispute arises.

Single-member LLCs benefit from an operating agreement just as much as multi-member ones, even though there is no one else to negotiate terms with.

An operating agreement is one of the clearest pieces of evidence that your LLC is a genuinely separate legal entity from you personally, which matters if a creditor or plaintiff ever tries to "pierce the corporate veil" and go after your personal assets.

Banks and future investors will also ask to see it before opening accounts or writing checks.

Have a lawyer review anything beyond a plain, single-member structure, especially once you have multiple members with different contribution types (cash versus sweat equity, for example), unequal ownership splits, or any plan to bring in outside capital later.

The cost of a short attorney review is small compared to the cost of unwinding a bad term after the fact.

5. Get an EIN from the IRS

Your Employer Identification Number (EIN) is the federal tax ID you will use to open a business bank account, hire employees, file taxes, and sign most vendor and payment-processor agreements.

It is free directly from the IRS, so never pay a third party's "EIN filing fee" for the number itself. That fee is for someone else's paperwork handling, not for the EIN, which the IRS never charges for.

If the LLC's responsible party has a Social Security Number or Individual Taxpayer Identification Number, you can apply online at irs.gov.

If you are a non-US founder without either, you apply by fax or mail using Form SS-4, since the IRS's online EIN tool requires a US taxpayer ID for the responsible party.

That paper route takes longer, so plan around it if you are racing a deadline. Our guide for non-US residents forming Delaware LLCs walks through that path step by step, including what the IRS actually asks for on Form SS-4.

A multi-member LLC needs an EIN regardless of how it plans to be taxed. A single-member LLC technically does not need one to exist, since the IRS lets it use the owner's SSN by default.

You will need an EIN anyway the moment you want to open a business bank account, since virtually no bank will open one on a personal SSN alone.

Get the EIN as soon as your certificate of formation is approved, rather than waiting until you are standing at the bank.

Keep the IRS's confirmation letter (the CP 575 or 147C) somewhere safe. Banks, payment processors, and even some registered agents will ask to see it more than once, and requesting a replacement copy from the IRS later is slower than filing away the original the day it arrives.

6. Open a business bank account

Keeping business money separate from personal money is not optional for an LLC; it is the operational habit that makes your liability protection real rather than theoretical.

Commingling funds, paying personal expenses from the business account or vice versa, is one of the fastest ways for a court to disregard the LLC entirely and treat you as personally liable for its debts.

Once your certificate of formation is approved and your EIN has arrived, opening a dedicated account should be one of your very first moves.

On the Rho banking platform: banking, invoicing, cards, and bill pay, all live the moment your account is approved. When you incorporate a Delaware C-corp with Rho, your Rho business account application opens in the same flow, subject to approval; Rho requires at least one US-based owner or officer, a US operating address, and a business in a non-excluded industry.

See how Rho compares with other options in our review of the best online business bank accounts.

If you are not sure an LLC is the right entity for where your business is headed, revisit the comparison table earlier in this guide.

Do that before you open accounts, contracts, and vendor relationships under a structure you may end up converting out of.

Whatever bank you choose, confirm what it needs before you apply: most ask for the approved certificate of formation (or a certified copy), the EIN confirmation letter, a government-issued ID for each authorized signer, and sometimes the operating agreement itself.

Having all four ready in one folder makes account opening much smoother.

7. Pay the $400 annual tax and set your compliance calendar

Every Delaware LLC owes a flat $400 annual tax, due on or before June 1, paid directly at corp.delaware.gov. Delaware revised its fee schedule effective August 1, 2026, so check older guides and renewal notices against the current $400 figure.

There is no annual report requirement for a Delaware LLC, just the tax itself, and the amount does not change based on revenue, profit, or how many members you have.

A dormant LLC that never did any business still owes the full $400 for every year it legally exists.

Miss the June 1 deadline and Delaware adds a $200 penalty, plus interest at 1.5% per month.

Beyond the dollar cost, an LLC that falls out of good standing cannot get a certificate of good standing from the state, which blocks financings, loan applications, and expansion into other states until the LLC is brought current.

Put these dates on your calendar the day your LLC is approved, not the week before they hit:

• June 1, every year: the $400 Delaware LLC annual tax, paid online at corp.delaware.gov.

• Your registered agent renewal date: typically the anniversary of when you signed up, and separate from the state's own deadline.

• March 15 or April 15: federal tax filing (March 15 for LLCs taxed as partnerships, April 15 for single-member LLCs reported on the owner's return), plus any home-state income tax return.

• Your home-state annual report: if you registered there as a foreign LLC under step 8, on whatever schedule that state sets.

For how Delaware's tax and reporting rules differ across LLCs, corporations, and partnerships, see our full Delaware franchise tax guide.

8. Register in your home state if you operate there

Forming in Delaware does not exempt your LLC from the rules of the state where you actually do business. If your LLC has an office, employees, or regular in-person operations in another state, meaning real physical presence, not just an occasional client call, you typically must register there as a foreign LLC.

That triggers a second filing fee (set by that state, not Delaware), often a second registered agent, and a second set of annual reports and fees running on top of Delaware's own.

This is the step founders skip most often, usually because nobody explains it during the excitement of forming the entity, and it is exactly why forming in Delaware is not automatically the right call for a small, local business with no plan to raise venture capital or operate across state lines.

If you will only ever operate in one state, forming there directly, rather than in Delaware and then registering as foreign in your home state, usually means one filing, one registered agent, and one annual fee instead of two of each.

Run the math on both filings before you commit to Delaware for a business that will never leave your home state. Add Delaware's $110 filing fee, $400 annual tax, and a registered agent to your home state's foreign-qualification fee, its own annual report or tax, and a second registered agent there.

Then compare that total to just forming directly in your home state. For many small operating businesses, Delaware's advantages, its well-developed case law and the Court of Chancery, matter far more to venture-backed companies than to a single-location consultancy or shop.

If you do end up raising venture capital later, investors will typically ask you to become a Delaware C corporation regardless of where your LLC is currently registered, and our guide to converting an LLC to a C corp explains how that conversion works, including the tax and cap-table mechanics involved.

What a Delaware LLC costs to form and keep

Here is every state charge from this guide, per the Delaware Division of Corporations fee schedule revised August 1, 2026 (as of October 17, 2026):

Every year after formation, the recurring state cost of keeping a Delaware LLC in good standing is the $400 annual tax, plus whatever your registered agent charges.

That figure does not include your home state's foreign-qualification fees and annual reports if step 8 applies to you, which can meaningfully change the total depending on where you operate.

Common mistakes to avoid when forming a Delaware LLC

Many Delaware LLC formations that go wrong fail in one of these six places. Checking this list against your own filing takes a few minutes and can save weeks of cleanup later.

• Filing before the name search actually clears. A name that looks available in a casual search can still get rejected at filing if it is too close to an existing entity. Always run the search on icis.corp.delaware.gov itself, not a third-party site's cached version, immediately before you file.

• Treating the operating agreement as optional paperwork. Delaware's default statutory rules apply to any LLC that never adopts its own agreement, and those defaults rarely match what the members actually want. Draft one before the LLC signs anything, even as a single-member LLC.

• Applying for an EIN before the certificate of formation is approved. Applying too early, or with a name that does not exactly match your approved certificate, is a common source of mismatched IRS records that take time to untangle.

• Commingling personal and business funds from day one. Using a personal account for the LLC's first few transactions "just until the business account is open" is one of the most common ways new owners accidentally undermine their own liability protection.

• Missing the June 1 annual tax deadline. The $400 tax is flat and applies to every Delaware LLC that exists during the year, and a late payment adds a $200 penalty plus 1.5% interest per month.

• Skipping foreign qualification where the business actually operates. An LLC that quietly does business in another state without registering there as a foreign LLC risks fines, back taxes, and, in some states, losing the right to enforce contracts in that state's courts until it registers.

After the paperwork: run it like a company

Once the LLC exists on paper, the habits matter more than the documents ever will. Keep business and personal finances strictly separate, sign every contract in the LLC's name rather than your own, keep your registered agent's information current with the state, and pay the annual tax on time every June.

These four habits, done consistently, are what actually preserve the liability protection you formed the LLC to get in the first place.

For Delaware LLCs on the Rho banking platform: banking, invoicing, cards, and bill pay, all live the moment your account is approved, so the operational side of running the company sits in one place.

And if your business outgrows the LLC structure down the line, whether that means bringing on outside investors or wanting the option pool and QSBS benefits a C corp offers, Rho Incorporation forms Delaware C-corps for $400 and LLCs for $349 all in, state filing fee included.

Revisit this guide each time something changes: a new member joins, you start selling into a new state, or you find yourself talking to investors.

The eight steps above only happen once, but the decisions behind them, which entity, which state, when to convert, are worth re-checking as the business grows rather than assuming the choice you made at formation is permanent.
