An S corporation in Delaware is a Delaware corporation that has elected federal S corporation tax status. You do not create an "S corporation" by filing a special Delaware entity. You form a Delaware corporation with the Delaware Division of Corporations, then file IRS Form 2553.
For a calendar-year corporation, the usual Form 2553 deadline is March 15. Delaware name reservation is optional and currently costs $75.
Delaware is not automatically the best state of formation for every small business. It may make sense when you expect outside investors, want Delaware corporate law, or have a specific legal or financing reason to incorporate there. If the business operates mainly in another state, forming there may avoid Delaware registered-agent fees, franchise tax and foreign-registration costs.

An S corporation is a federal tax election. The IRS generally requires an S corporation to be a domestic corporation with no more than 100 shareholders, eligible shareholders, one class of stock and no status as an ineligible corporation.
Is Delaware the Right State for an S Corporation?
Delaware can be a reasonable choice when the business expects venture capital or institutional investment, may issue equity to several owners, or needs Delaware corporate law and Court of Chancery precedent.
Other reasons to consider Delaware include:
- Owners or operations spread across several states
- A planned financing or ownership structure that benefits from Delaware law
- Advice from a business attorney or tax professional
- A need for a familiar corporate-law framework for investors
Forming in Delaware does not remove registration requirements in the state where the business operates. A Delaware corporation may need to register as a foreign corporation, obtain local licenses and pay taxes in another state.
For a local business that operates entirely elsewhere, compare the costs of forming in with the cost of maintaining a Delaware corporation. Include the annual quote from.
How to Choose and Reserve a Delaware Corporate Name
Choose a name that is distinguishable from existing Delaware entities and includes an approved corporate identifier, such as "Corporation," "Incorporated," "Company" or an abbreviation.
Name reservation is optional. Delaware allows a name to be reserved for 120 days, and the current reservation fee is $75.
Before filing, check:
- Federal and state trademark conflicts
- Domain-name availability
- Social-media and brand availability
- Whether the name accurately describes the business
A Delaware name reservation does not create trademark rights.
How to Appoint a Delaware Registered Agent
Every Delaware corporation must maintain a registered office and registered agent in Delaware. The agent receives service of process and certain official communications.
The registered agent may be:
- A Delaware resident
- A Delaware corporation or LLC authorized to act as an agent
- Another authorized business entity
- The corporation itself, if it has an appropriate Delaware physical address and remains available during business hours
A Delaware registered agent must maintain a physical street address in the state. A commercial registered-agent company is common when the owners do not live or work in Delaware.
Delaware does not set one universal commercial registered-agent price. The agent's annual fee is an additional operating cost.
How to File the Delaware Certificate of Incorporation
File a Certificate of Incorporation with the Delaware Division of Corporations. Delaware provides forms and accepts submissions through its document filing service or by mail.
The certificate generally identifies:
- The corporation's legal name
- The Delaware registered office and registered agent
- The corporation's purpose
- The number of authorized shares
- The shares' par value, or a statement that they have no par value
- The incorporator
For an S corporation, use a simple structure with one class of common stock. An S corporation can lose eligibility if it creates multiple classes of stock with different economic rights. Voting differences may be allowed in limited circumstances, but an attorney should review the structure before filing.
The Delaware corporate filing fee depends on the filing and share structure. Use the state's current corporate fee schedule or filing calculator instead of assuming one flat fee.
How to Organize the Corporation After Formation
Filing the certificate creates the corporation, but the company still needs internal records and approvals.
The incorporator or initial directors should:
- Adopt corporate bylaws.
- Appoint the initial director or directors.
- Appoint officers, such as a president, secretary and treasurer.
- Approve the corporation's bank account.
- Approve the issuance of shares.
- Record ownership in a stock ledger.
- Approve initial contracts, intellectual-property assignments and business policies.
- Keep signed consents and resolutions in a corporate record book.
Delaware law permits a corporation's board to have one or more natural-person directors. One person may also hold multiple corporate offices unless the certificate or bylaws provide otherwise.
A single-owner corporation can therefore have one shareholder, one director and one person serving in several officer roles.
How to Obtain an EIN
Apply for an Employer Identification Number after the corporation has been legally formed. The IRS issues EINs online, by fax or by mail, and does not charge a fee for the application.
You generally need the EIN to:
- Open a business bank account
- Hire employees
- File corporate tax returns
- Run payroll
- Apply for licenses
- Establish business credit
The EIN application identifies the corporation's responsible party, usually its principal officer. The responsible party must be an individual, not a nominee or formation service.
How to File IRS Form 2553
After forming the corporation, file Form 2553, Election by a Small Business Corporation, with the IRS.
Form 2553 generally must be filed:
- No later than 2 months and 15 days after the beginning of the tax year in which the election should take effect, or
- During the preceding tax year
For a calendar-year corporation seeking S corporation status beginning January 1, the normal deadline is March 15. If March 15 falls on a weekend or federal holiday, the deadline may move to the next business day.
All shareholders generally must sign the shareholder-consent section of Form 2553. Keep the completed form and proof of submission with the corporation's permanent records.
For a newly formed corporation, the effective date is usually tied to the earliest date the corporation had shareholders, assets or began doing business.
What Happens If Form 2553 Is Filed Late?
Late-election relief may be available when the corporation had reasonable cause, acted promptly after discovering the error and meets the other IRS requirements. The IRS instructions describe relief that may apply within three years and 75 days of the intended effective date.
Late filing does not guarantee approval. A tax professional should review the corporation's facts before relying on late-election relief.
How to Register for Delaware Licenses and Payroll Accounts
If the corporation conducts business in Delaware, it generally must obtain a Delaware business license through the state's One Stop system. Delaware states that the annual license fee is generally $75 for a first location, although the amount can vary by business activity. Separate licenses may apply to separate activities.
A corporation with Delaware employees may also need to register for:
- Delaware employer withholding
- Unemployment insurance
- Workers' compensation requirements
- Local or county licenses
- Industry-specific permits
Delaware employers must register for state withholding and provide employees with Form W-2 reporting their wages and Delaware tax withheld.
If the corporation operates mainly in another state, check that state's foreign-registration, payroll, income-tax and licensing rules.
What Does a Delaware S Corporation Cost?
A typical Delaware domestic, non-exempt corporation should budget for the following:
| Cost or obligation | Current amount or rule |
|---|---|
| Name reservation | $75, optional |
| Certificate of Incorporation | Variable under Delaware's corporate fee schedule |
| Registered agent | Private annual fee |
| EIN | Free from the IRS |
| Form 2553 | No IRS filing fee |
| Delaware annual report | $50 for a non-exempt domestic corporation |
| Delaware franchise tax | Minimum generally $175 under the Authorized Shares Method |
| Delaware annual state charges | At least $225 in the common minimum case, before agent and license costs |
| Delaware business license | Generally $75 for a first location, if conducting business in Delaware |
Delaware domestic corporations must file the annual report and pay franchise tax by March 1. The minimum franchise tax is generally $175 under the Authorized Shares Method and $400 under the Assumed Par Value Capital Method. Delaware applies the method relevant to the corporation. Late filing can result in a $200 penalty plus interest.
Delaware assesses franchise tax when the corporation remains active in the state's records during the tax year. Closing a bank account or stopping operations does not automatically dissolve the corporation or end its franchise-tax obligations.
How Is a Delaware S Corporation Taxed?
Delaware recognizes the federal S corporation election and does not impose Delaware corporate income tax on pass-through income. An S corporation with Delaware-source income must generally file Delaware Form SCT-RTN, the S Corporation Reconciliation and Shareholders Information Return. Delaware may also require estimated personal income-tax payments for nonresident shareholders.
The corporation may still have:
- Delaware franchise tax
- Delaware gross receipts tax
- Delaware payroll withholding
- Federal payroll taxes
- Federal Form 1120-S filing obligations
- State tax filing obligations in other states
- Personal income-tax obligations for shareholders
An S corporation must generally file federal Form 1120-S and provide shareholders with Schedule K-1 information. Shareholders report their allocated income, deductions and credits on their personal returns.
How Should an S Corporation Pay an Owner?
An owner who performs services for the S corporation is generally a shareholder-employee. The corporation should pay reasonable compensation through payroll before making non-wage shareholder distributions.
The IRS can reclassify distributions as wages when they are actually compensation for services. Relevant factors include the owner's duties, experience, time commitment, compensation paid to other employees and comparable market pay.
The S corporation election does not allow an owner to take all business profit as distributions without payroll. A compensation policy, payroll records and support for the salary amount help document the corporation's treatment.
What Is the Current BOI Reporting Position?
As of September 20, 2026, a corporation created in the United States is exempt from federal Beneficial Ownership Information reporting under FinCEN's rule that became effective August 14, 2026. A newly formed domestic Delaware corporation therefore does not currently file a BOI report with FinCEN solely because it was incorporated in Delaware.
FinCEN rules can change, so verify the current position before relying on this exemption for a later filing.
