How to Start a Business in Delaware: Steps, Costs and Requirements

Over 334,000 new businesses were registered in Delaware in 2025 alone. If you’re planning to add yours to the list, picking the state is the easy part. You’ll still need to settle on a legal structure, make your company officially registered, and sort out the licenses and taxes that come with running it. Your plans for Delaware make a difference here. It’s because forming an LLC or corporation and running your business in the state don’t follow quite the same playbook. To help you plan ahead, this guide walks you through how to start a business in Delaware, from forming your company to getting it ready to operate. You’ll also get a breakdown of the costs and annual deadlines to plan for.

Does Starting a Business in Delaware Mean Forming There or Operating There?

It can mean either, or both. Forming the company gives it legal status under the state law. Running it means following the rules that apply to your day-to-day activities. Here’s how that can play out:

• You form your company and operate in Delaware.
• You establish your company in Delaware and carry out business activities in another state.
• You register an LLC or corporation in another state and do business in Delaware.

Say you form an LLC in Delaware but set up your business location in California. You may need to register your company in California, too, under its foreign qualification rules. If you do, you’ll need a Certificate of Good Standing from Delaware and a registered agent in California. You should also meet California’s applicable tax, licensing, and filing rules. On the Delaware side, you’ll still pay an annual LLC tax, maintain a local registered agent, and keep up with any other filings tied to your company. It works the other way around too. A California LLC operating in Delaware may need to register as a foreign LLC there, while still meeting its home state’s tax and filing rules. Here’s how the choices compare:

Factors	Formation state	Operating state
What it means	The state where you legally register your LLC or corporation.	The state where you carry out business activities.
Registration	File formation documents with the state.	Register as a foreign entity if required.
Registered agent	Maintain a registered agent in the formation state.	You generally need a local registered agent
Taxes and filings	Meet annual tax and filing rules for your entity type.	Follow applicable state and local tax, licensing, and reporting rules.

Step 1: Choose a Business Structure

First up, your business structure. This choice shapes who owns the company, how it’s taxed, and how much personal liability you carry. You have four main options to consider here:

Business structure	Who might consider it?	What to know before choosing
Sole proprietorship	You plan to run a business on your own without forming a separate legal entity.	There's no legal separation between you and the business. You're personally responsible for its debts, and profits are generally reported on your personal tax return.
Partnership	You're starting a business with another person or group.	Ownership and decision-making can be shared. Personal liability depends on the partnership type, so check the rules before settling on one.
Limited liability company (LLC)	You want a separate legal entity with one or more owners.	Members generally have personal liability protection. You can manage the company yourself or appoint managers, and federal tax treatment varies by ownership and elections.
Corporation	You plan to issue shares, bring in investors, or establish a formal ownership structure.	Shareholders generally have limited liability. Corporations have directors, officers, and more formal recordkeeping. A C corporation generally pays corporate income tax, and shareholders may also owe tax on dividends.

Here, you can also elect S corporation tax treatment for an eligible LLC or corporation by filing IRS Form 2553. This changes how the IRS taxes your business, but your legal structure in Delaware stays the same. If you’re weighing more than one option, consult an attorney or tax professional for advice personalized to your business plans.

Step 2: Choose a Business Name and Check its Availability

Delaware requires you to pick a name that’s clearly different from those already registered or reserved in the state. So, before you settle on one, check its availability through the Division of Corporations’ entity search. Business names should also have the approved ending. For example, LLC names should end with “LLC” or “Limited Liability Company.” The state lets you reserve an available entity name for 120 days at $75 per name if you’re not ready to file yet.

You can also operate under a trade name or DBA (Doing Business As) if you want customers to know your business by a different name. Delaware now accepts trade name registrations through Delaware One Stop. To register, you’ll need a business license or a $25 annual Trade Name-Only License if your entity doesn’t require the standard license. You’ll also pay a separate one-time DBA registration fee of $25. A name available in Delaware’s business records isn’t necessarily free to use as a brand. Another company could already have trademark rights to it. So, check the USPTO trademark database for existing marks and look into domain availability before settling on your name.

Step 3: Appoint a Delaware registered agent

Your Delaware company must have a registered agent (even if you run it from another state). They will receive legal papers, including service of process, and official notices on your company’s behalf. The state requires the agent to maintain a physical street address and be available during normal business hours. A P.O. box, mail-forwarding address, or a virtual address alone won’t meet that rule. You can be your own agent, appoint someone from your friends and family, or hire a registered agent service provider. If you’re bringing in a professional service, here’s what to look for:

• Confirm availability: Make sure the agent can receive legal documents during usual business hours.
• Verify the address: Confirm the agent has a Delaware street address and is not a mail-forwarding service.
• Clarify responsibilities: Ask about the mode of sending the documents to you (by email or physical delivery) and what the timeline is.
• Compare annual prices: Check the yearly service fee, renewal terms, and any extra charges for forwarding documents.

Step 4: File to Form Your Business or Qualify it in Delaware

This is the point when your business plans turn into an official state filing. Delaware’s Division of Corporations, under the Secretary of State, is the office you’ll deal with. The following is how it works for different business structures.

Form a Delaware LLC or corporation

If you’re starting a new LLC, file a Certificate of Formation. You’ll need your business name, your registered agent’s name and Delaware street address, and an authorized person’s signature. The state filing fee is $110. Corporations should file a Certificate of Incorporation. For this, you will need more details, including the number of shares the company is authorized to issue, their par value, and incorporator information. The filing fee starts at $109, but the final amount varies with the authorized stock. The filing process is the same for both. Pick up the right form from Delaware’s Division of Corporations website, complete it, and send it through the state’s online document filing service or by mail. Delaware’s standard filing process typically takes 10-15 business days, but it can extend up to 3-4 weeks during busy periods. Expedited processing is also available for an extra fee.

What changes when you’re only operating in Delaware?

If you are already registered in another state, apply for Registration of a Foreign Limited Liability Company for an LLC. You will need the original formation details, a Delaware-registered agent, and a Certificate of Existence from its home state issued within the last 6 months. The filing fee is $200.For corporations, complete Delaware’s Qualification of Foreign Corporation. Here you will need additional information, including your statement of assets and liabilities and the purpose of doing business in the state. The filing fee for this certificate is $245.

Start as a sole proprietorship or partnership

A sole proprietorship doesn’t require formation documents or a filing fee with Delaware’s Division of Corporations. You’re operating the business in your own name, without creating a separate legal entity. You still need a Delaware business license if you conduct business in the state. The annual fee starts at $75 for your first location. Extra locations and your line of work can push the cost higher.The next business type is the partnership. We have 3 types to consider:

• A general partnership can operate in Delaware without filing formation documents. You can still file an optional Statement of Partnership Existence to record the company’s name, registered office, and registered agent’s details. The filing costs $200. You’ll also pay a $400 annual tax, due June 1.
• A limited partnership (LP) must file a Certificate of Limited Partnership. You’ll need the business name, registered agent’s details, and the name and address of each general partner. The filing costs $200, with a $400 annual tax, and is due on June 1.
• A limited liability partnership (LLP) needs a Statement of Qualification to register in Delaware. The initial filing costs $300 per partner, up to $180,000. You’ll pay the same amount each year when submitting the LLP’s annual report by June 1.

Step 5: Get an EIN and Set Up Business Finances

An Employer Identification Number (EIN) is your business’s nine-digit federal tax ID. The IRS provides it for free and uses it to identify your company for tax purposes, and banks often request it when you open a business account. Sole proprietors without employees generally don’t need this. You can still get one for banking needs or if you plan to hire employees or change your business structure later.

With your EIN sorted, the next step is opening a business bank account. It keeps your personal and company finances separate, as mixing those funds can put your personal liability protection at risk. Give your bookkeeping an early start, too. Record your income and expenses, and keep bank statements, invoices, and receipts to support your tax filings. You can utilize accounting software or a simple recordkeeping system, provided it accurately tracks your transactions.

Step 6: Register for a Delaware Business License

Forming a company in Delaware and getting permission to operate in the state are two separate processes. If you’re conducting business in the state, you’ll generally need a license from the Division of Revenue. Apply for it through the Delaware One Stop Licensing and Registration Service. Start by selecting the option that matches your business structure and registration status. After registering, you can print a temporary license. Delaware generally mails the permanent copy within 10 working days. Most licenses expire on December 31 and require annual renewal.

You can also opt for a three-year license after your first year. Selling online doesn’t automatically exempt you from Delaware’s registration rules. Even without a physical store, you still need to check whether your business activities require state registration or a business license. Delaware One Stop lists having an office or property in the state, employees working there, and local sales as reasons you may need a business license. For less clear-cut cases, you can submit the Nexus questionnaire to the Delaware Division of Revenue for clarification.

Additional registrations for Delaware employers

If you hire employees who work in Delaware, you’ll also need to check the state’s employer registration requirements. Depending on your business and employees, these include:

• Registering for income tax withholding with the Delaware Division of Revenue.
• Getting workers’ compensation insurance if your business is required to carry it.
• Registering for unemployment insurance with the Delaware Department of Labor.

Delaware One Stop’s employer instructions cover more on this.

Step 7: Check Local and Industry-Specific Requirements

After the state registration and business license, you may still have a few local rules to tick off. The exact needs come down to 2 factors:
Local requirements. For example, if your corporation plans to build a manufacturing facility in Wilmington, you’ll need a building permit and must check that the site meets the city’s zoning rules.
Industry-specific requirements. Say you’re opening a restaurant or bakery, you will need a food establishment permit from Delaware’s Division of Public Health. This is a statewide requirement that applies wherever you operate in Delaware.

Step 8: Plan for Taxes, Fees, and Annual Filings

Starting a business in Delaware comes with upfront and ongoing costs. Plan for both so you can budget for setting up your company and keeping it running. Here are the typical expenses to account for.

Understand which Delaware taxes apply

Delaware has no state or local sales tax, but that doesn’t give your business a free pass. Here are the taxes that could land on your plate, depending on your business structure and activities.

• Gross receipts tax: Delaware charges this tax on your gross revenue from goods sold or services provided in the state, without deducting business expenses. The rate falls between 0.0945% and 1.9914%, as per your business category. Petroleum products have a separate rate.
• Corporate income tax: Corporations conducting business in Delaware generally file a state income tax return. It charges an 8.7% corporate income tax on the portion of your company’s taxable income assigned to the state.
• Corporate franchise tax: Delaware corporations pay this every year, even if your company operates entirely in another state. Delaware calculates it using either the Authorized Shares Method, with a minimum of $175. Or with the Assumed Par Value Capital Method, which has a minimum of $400. The second one considers your company’s shares and assets.

Apart from all this, you’ll pay a $400 annual tax for your Delaware LLC starting with the 2026 tax year. If you own a corporation, you’ll file your annual report (costs $50) and pay franchise tax. Foreign corporations must file this report for $250.
Here’s a quick look at what your business needs to pay or file, how much it costs, and when it’s due.

Tax or filing	Business entity	Common cost range	Due date
Gross receipts tax	Businesses operating in Delaware	0.0945%-1.9914%	Monthly or quarterly, depending on your filing frequency.
Corporate income tax	Corporations conducting business in Delaware	8.70%	April 15 for calendar-year corporations
Corporate franchise tax	Corporations	From $175 or $400, according to calculation method	March 1
LLC annual tax	LLCs	$400 for tax year 2026	June 1, 2027
Domestic corporation annual report	Delaware domestic corporations	Generally $50	March 1
Foreign corporation annual report	Corporations formed elsewhere and registered in Delaware	$250	June 30
