Starting a Delaware LLC is simple on paper, but Delaware is not automatically the best state for every small business. The formation fee is $110, and every LLC must keep a registered agent with a physical Delaware address.
The big change for 2026 is the annual LLC tax. It rose from $300 to $400 for tax year 2026. Delaware LLCs still do not file an annual report, but owners need to understand the tax deadline and the cost of missing it.
Delaware LLC costs at a glance
The state filing fee for a domestic Delaware LLC is $110. Name reservation is optional and costs extra. A commercial registered agent also charges its own fee if you need one.
The Delaware Division of Corporations LLC tax instructions explain that LLCs owe a $400 annual tax for tax year 2026. The tax is due June 1 following the close of the calendar year. Delaware LLCs do not file the corporation annual report.
Step 1: Choose a Delaware LLC name
Your name must be distinguishable from names already on Delaware records and include an accepted LLC ending. Search the state database before you spend money on branding.
If the public brand matters, also check domain names and possible trademark conflicts. State approval of an entity name does not create broad trademark rights.
Step 2: Choose a registered agent
Every Delaware LLC needs a registered agent with a physical street address in Delaware. The agent receives lawsuits, tax notices, and other official documents for the company.
If you live and operate elsewhere, you will usually hire a commercial agent. That recurring private cost is one reason the real price of a Delaware LLC is higher than the $110 filing fee.
Step 3: File the Certificate of Formation
The Certificate of Formation creates the LLC. Delaware keeps this document fairly short. It identifies the company and its registered office and agent, while detailed ownership and management rules normally stay in the private operating agreement.
The $110 formation fee is separate from the annual tax. For tax year 2026, the repeating state LLC tax is $400.
A 2026 LLC generally pays its first $400 tax in 2027
An LLC formed during 2026 is generally assessed for that calendar year, with the tax due June 1, 2027. The tax is not prorated simply because the company formed late in the year.
Missing the deadline gets expensive. Delaware lists a $200 late-payment penalty, plus interest at 1.5% per month on unpaid tax and penalty. Put the deadline on the company calendar as soon as the LLC is formed.
Delaware is useful, but it is not magic
Delaware has a mature body of business law and a Court of Chancery that handles many business disputes. Its LLC law also gives owners broad flexibility to define rights and duties in an operating agreement.
Those features can matter to companies with investors, complex ownership, large transactions, or lawyers who regularly work with Delaware entities. They may matter much less to a one-owner local service company.
Your home state may be simpler
If you live and operate in another state, forming in Delaware can create two layers of compliance. Our Colorado LLC guide shows how a local company can compare home-state filing costs before adding Delaware registration on top.
A Delaware LLC that actually does business elsewhere may need foreign registration in that state. That can mean another filing fee, another registered agent, another tax calendar, and local licenses.
California is a good example. Our California LLC guide explains why forming elsewhere does not automatically remove California registration or tax duties when the business operates there.
Step 4: Write an operating agreement
Even a one-owner LLC benefits from a written operating agreement. For a multi-member company, the document is much more important because it can define voting, management, contributions, distributions, ownership transfers, buyouts, disputes, and dissolution.
Keep signed formation and operating documents together. A business document organizer on Amazon can help keep paper copies of the formation certificate, operating agreement, licenses, and tax notices in one place.
Step 5: Get an EIN when needed
An Employer Identification Number is the federal tax number issued by the IRS. Many LLCs need one for employees, payroll, multi-member tax filings, banking, or tax elections. The IRS does not charge a fee to issue an EIN.
Your Delaware LLC and its federal tax treatment are separate questions. A single-member LLC is commonly disregarded for federal income tax unless it elects another treatment. A multi-member LLC is commonly taxed as a partnership unless it elects corporate treatment.
Step 6: Separate business money
Open a business bank account and keep company income and expenses separate from personal spending. Record owner contributions, reimbursements, and distributions clearly.
Good records make taxes and bookkeeping easier. They also support the basic separation between the company and its owners. This small-business startup guide gives another practical view of organizing the business side before growth makes the paperwork harder.
Step 7: Check licenses and Delaware taxes
Formation with the Division of Corporations is not the same as a business license. A company operating in Delaware may need a Delaware business license, professional permits, or local approvals.
Delaware does not impose a state or local sales tax, but some businesses can face gross receipts tax. “No sales tax” does not mean “no business tax.”
Keep the registered agent and tax calendar current
The registered agent is not just a formation detail. The LLC needs a valid Delaware agent while it remains active. Update the state record if the agent changes.
It also helps to compare the full yearly burden across states. Our Connecticut LLC guide shows a different model: an annual report fee rather than Delaware’s larger flat LLC tax. The cheapest formation fee does not always produce the cheapest long-term company.
Common Delaware LLC mistakes
- Following an old guide that still lists the annual LLC tax as $300.
- Thinking Delaware LLCs file the corporation annual report.
- Missing the June 1 tax deadline.
- Forgetting the $200 late penalty and monthly interest.
- Letting the registered-agent information become outdated.
- Operating in another state without checking foreign-registration rules.
- Mixing personal and company money.
Delaware works best when you have a reason
Delaware can be an excellent home for an LLC, but the choice should fit the business. Form the company correctly, keep a valid registered agent, write a useful operating agreement, separate the money, and register wherever the company actually operates.
Most of all, remember the 2026 tax change. The annual Delaware LLC tax is $400, not $300. A company formed during 2026 will generally have that tax due June 1, 2027.
