Delaware business license guide

Last checked: April 26, 2026

Delaware is not like every state. It has a state business license through the Delaware Division of Revenue, no state or local sales tax, and a gross receipts tax system that many new owners miss.

This guide explains the Delaware state license, entity filing, trade names, employer steps, local permits, and common industry licenses in plain English.

The short answer

Most people who conduct business in Delaware need a State of Delaware Business License from the Delaware Division of Revenue. Delaware says any person or entity conducting a trade or business in the state, including corporations, must obtain this state license.

This is separate from forming an LLC or corporation with the Delaware Division of Corporations. It is also separate from city, town, county, zoning, health, alcohol, professional, contractor, environmental, and employer rules.

Delaware also does not issue a normal sales tax permit because the state has no state or local sales tax. Instead, Delaware uses business licenses and gross receipts tax for many goods and services.

Delaware facts box

Question	Delaware answer
Does Delaware have a statewide business license?	Yes. The Delaware Division of Revenue says any person or entity conducting a trade or business in Delaware, including corporations, must obtain a State of Delaware Business License.
Main state portal	Delaware One Stop is the main online portal for state business registration and licensing.
Typical state license fee language	The Division of Revenue says the annual fee varies, but is generally $75 for a first location. A separate license is required for each separate business activity.
Sales tax permit?	No normal Delaware sales tax permit. Delaware says there are no state or local sales taxes, so sales tax exemption certificates and reseller certificates are not applicable.
Delaware tax issue many owners miss	Delaware has gross receipts tax on many sellers of goods and providers of services. The tax is imposed on the seller or service provider, not the customer.
DBA term	Delaware uses “trade name,” often called DBA. As of February 2, 2026, new trade name registrations are handled through the Division of Revenue and Delaware One Stop.
Entity filing office	LLCs, corporations, and other entities are handled by the Delaware Division of Corporations, not the Division of Revenue.
Local layer	Your city, town, or county may require a local business license, zoning approval, building permit, certificate of occupancy, home occupation approval, or local tax account.

Which government layer handles which step?

Do not treat every filing as one “business license.” Delaware licensing is layered.

Layer	What it may handle	Delaware example
Federal	Federal tax ID, federal regulated industries, federal employer tax rules, and certain national permits.	The IRS issues an EIN. FinCEN currently says entities created in the United States are exempt from federal BOI reporting, but foreign reporting companies may still have BOI duties.
State of Delaware	State business license, gross receipts tax, entity filings, withholding, unemployment insurance, workers’ compensation registration, professional licenses, and many industry permits.	Delaware One Stop, Division of Revenue, Division of Corporations, Division of Professional Regulation, Department of Labor, DNREC, and other state agencies.
County	Building permits, zoning, land use, contractor licensing, certificates, county-owned system rules, and some unincorporated-area approvals.	New Castle County, Kent County, and Sussex County each list local permit or zoning resources.
City or town	Local business license, local finance registration, zoning approval, home occupation approval, certificate of occupancy, sign permits, fire review, food truck siting, and local inspections.	Wilmington, Newark, Dover, Middletown, and New Castle each have local business or permit rules that can apply in city or town limits.
Private platform or marketplace	Seller rules, account verification, insurance, product categories, shipping rules, and marketplace policies.	An online marketplace may ask for a tax ID or business information, but that does not replace the Delaware state license or local approvals.

Delaware state business license

The main state license is issued by the Delaware Division of Revenue. Delaware’s state guidance says any person or entity conducting a trade or business in the state must obtain a State of Delaware Business License.

Use Delaware One Stop registration and licensing to start or manage this process. The One Stop system can also connect you to unemployment insurance, workers’ compensation, entity resources, and the IRS EIN page.

What the state license does

Registers the business activity with the Delaware Division of Revenue.
Helps set up Delaware tax accounts that may apply to your activity.
May lead to gross receipts tax filing duties.
May be needed before a Delaware trade name registration.
May be required before a city license, such as in Wilmington.

What it does not do

It does not form an LLC or corporation.
It does not replace a professional license.
It does not replace food, alcohol, environmental, contractor, health, or safety permits.
It does not guarantee that your location is zoned for your business.
It does not replace a city, town, or county license where local rules apply.

Practical tip: Before applying, know your legal name, business activity, location, ownership structure, federal EIN or owner tax ID, and whether you will have employees in Delaware.

LLC, corporation, and entity filing in Delaware

Entity formation is handled by the Delaware Division of Corporations. This is different from the Division of Revenue business license.

If you form a Delaware LLC or corporation, you still need to check the Division of Revenue license step if you conduct business in Delaware. If your entity was formed in another state and will operate in Delaware, check Delaware’s foreign qualification process through the Division of Corporations and Delaware One Stop.

Situation	What to check	Where to start
Sole proprietor using your legal name	You may not need an entity filing, but you still may need the Delaware state business license and local approvals.	Division of Revenue through Delaware One Stop.
Sole proprietor using a business name	You may need a Delaware trade name registration after getting the required Delaware business license.	Delaware One Stop trade name registration.
Delaware LLC or corporation	Form the entity with the Division of Corporations, then handle the Division of Revenue license and tax steps.	How to form a new Delaware business entity.
Out-of-state LLC or corporation operating in Delaware	Check foreign qualification, Delaware business license, state tax accounts, local licensing, and industry permits.	Delaware One Stop structure guidance.
Business with employees in Delaware	Check Delaware withholding, unemployment insurance, and workers’ compensation registration.	Delaware One Stop and Delaware Department of Labor.

Do not confuse formation with licensing. A Delaware LLC filing creates a legal entity. It does not, by itself, mean you are licensed to conduct a regulated business, open at a specific address, hire employees, or skip local approvals.

Trade names and DBAs in Delaware

Delaware uses the term trade name. Many people call this a DBA, “doing business as” name, fictitious name, or business name.

As of February 2, 2026, Delaware’s new trade name process is handled through the Division of Revenue and Delaware One Stop. Before that change, Delaware trade names were handled through county Prothonotary offices in the Superior Court system.

Key Delaware trade name details

A valid Delaware Division of Revenue business license is required to register a trade name.
The new registration is statewide, not county-by-county.
The stated fee is a one-time $25 charge per trade name.
Trade names themselves do not expire or renew, but the underlying business license must stay active.
A Trade Name-Only License may apply when a business does not operate in Delaware but needs to register a Delaware trade name.
Existing trade names previously recorded with Delaware Superior Court remain recognized, but optional re-registration into the Division of Revenue registry may be available.

A trade name is not trademark protection. Delaware’s Division of Revenue says DBA registration does not give exclusive rights to the name and does not stop others from using the same name. If brand ownership matters, ask a qualified trademark professional.

Sales tax, reseller certificates, and Delaware gross receipts tax

Delaware does not have state or local sales tax. The Delaware Division of Revenue says sales tax exemption certificates and reseller certificates are not applicable in Delaware.

That does not mean Delaware businesses have no tax duties. Delaware imposes license and gross receipts taxes on many sellers of goods and providers of services. The Division of Revenue explains that gross receipts tax is imposed on the seller or service provider and that there are no deductions for items such as cost of goods, labor, delivery, interest, or other expenses unless a statute says otherwise.

What this means in plain English

You usually do not collect Delaware sales tax from customers.
You may still owe Delaware gross receipts tax based on your business activity.
Your business activity classification matters because rates and filing frequency can vary.
If you have more than one type of activity, separate gross receipts reporting may be required.
Do not assume “no sales tax” means “no Delaware tax account.”

Online sellers: If you sell online but operate from Delaware, check Delaware Division of Revenue rules. If you are outside Delaware and sell to Delaware customers, check whether you have Delaware nexus or any other state tax duty before assuming nothing applies.

If you hire employees in Delaware

Employer setup has both federal and Delaware steps. The IRS issues the federal EIN. Delaware One Stop can guide employer registration with state agencies.

Delaware’s Division of Revenue says that if you will have employees in Delaware, you should continue in One Stop to register with the Delaware Division of Unemployment Insurance and the Division of Workers’ Compensation. Delaware’s withholding guidance also says the easy rule is: if you withhold federal tax, then you must withhold Delaware state tax.

Get an EIN directly from the IRS EIN page if your business needs one.
Open the correct Delaware withholding account if you will withhold Delaware income tax.
Register with the Delaware Division of Unemployment Insurance when required.
Check workers’ compensation requirements through the Delaware Department of Labor.
Ask whether new hire reporting, payroll tax filing, posters, insurance, and local employer taxes apply.

Do not pay a random website for an EIN. The IRS says you can get an EIN online for free. Use the official IRS website.

Industry-specific Delaware licenses and permits

The Delaware business license is not the only possible approval. Some work requires a separate state license, permit, inspection, or board approval.

Common Delaware agency examples

Professional licenses: The Delaware Division of Professional Regulation handles many professional and business licenses through DELPROS. DPR says a professional license is not the same as a Delaware Division of Revenue business license, and many businesses need both.
Food businesses: The Delaware Office of Food Protection handles retail food protection and food establishment permit matters. Check before opening a restaurant, bakery, caterer, mobile food unit, temporary food stand, or similar food operation.
Alcohol: The Delaware Office of the Alcoholic Beverage Control Commissioner handles liquor license applications, modifications, inspections, and renewals.
Agriculture, nursery, and pesticides: The Delaware Department of Agriculture lists permits and licenses for pesticide businesses, pesticide dealers, nursery industry activity, timber harvesting, agriculture dealers, and other regulated activities.
Environmental activity: The Delaware Department of Natural Resources and Environmental Control may require permits for certain commercial or industrial facilities and activities that may affect air, water, land, waste, or public health.
Contractors: Delaware Division of Revenue has specific contractor guidance for resident and non-resident contractors. Construction work may also trigger local permits, inspections, and contractor licensing.

Ask before spending money. For food, alcohol, construction, salon, health care, childcare, environmental, or mobile operations, contact the licensing agency before signing a lease, buying equipment, or ordering a vehicle build-out.

City, town, county, and zoning rules in Delaware

Delaware’s state license does not erase local rules. Delaware Business First Steps says your principal business location and any additional sites where you provide sales or services can determine whether you need county, city, or town licenses or permits.

Some Delaware municipalities issue their own business licenses. Some local approvals are about the location, not the business name. These may include zoning, building permits, certificates of occupancy, signs, fire review, grease traps, mobile vending locations, parking, customer traffic, or home occupation limits.

Local examples to show the pattern

Wilmington: The city says business owners operating within city limits must have a state business license and a city business license.
Newark: The city says a business license is required for businesses operating in the City of Newark.
Dover: City materials say a city license is needed if you are working within city limits.
Middletown: The town says business licenses are required for everyone who does business in Middletown, including contractors working within town limits and businesses located within town limits.
City of New Castle: The city says a business located in or doing business within the incorporated city limits is required to obtain a city business license each year.

Check local rules before you open. A Delaware state license may let you register with the state. It does not prove your address is approved for your business use.

Home-based businesses in Delaware

A home-based business may still need a Delaware state business license. It may also need local zoning approval or a home occupation review.

Home rules depend on the city, town, county, zoning district, lease, HOA, and the type of activity. A quiet bookkeeping business is not the same as a food business, auto repair activity, daycare, salon, contractor storage yard, or business with employees and customer visits.

Questions to ask before operating from home

Is this address inside a city or town, or in an unincorporated county area?
Does the zoning office allow this business activity at my home?
Do I need a home occupation permit, no-impact home occupation approval, or certificate of occupancy?
Are customer visits, employees, parking, signs, deliveries, equipment, or outdoor storage limited?
If I sell food, do home kitchen, cottage food, retail food, or temporary food rules apply?
If I rent property or host short-term stays, do local rental, lodging, fire, zoning, or tax rules apply?

Step-by-step Delaware checklist

Define the business activity. Write down what you sell or do, where you do it, and whether customers come to you.
Choose the business structure. Decide whether you are a sole proprietor, partnership, LLC, corporation, or foreign entity operating in Delaware.
Handle entity filing if needed. Use the Delaware Division of Corporations for LLCs, corporations, and foreign qualification.
Get an EIN if needed. Use the official IRS EIN page. Do not pay a third-party site unless you knowingly want paid help.
Apply for the Delaware state business license. Use Delaware One Stop and the Division of Revenue.
Check your business activity category. Your license type can affect gross receipts tax accounts, reporting, and separate licenses for separate activities.
Register a trade name if you use one. Use Delaware One Stop if the business name is not the same as your legal name or registered entity name.
Set up employer accounts if hiring. Check Delaware withholding, unemployment insurance, workers’ compensation, and federal payroll rules.
Check industry licenses. Look at DPR, Food Protection, OABCC, Agriculture, DNREC, Transportation, Labor, or other agencies based on your activity.
Check city, town, and county rules. Confirm local business license, zoning, building, fire, health, home occupation, sign, and certificate of occupancy rules.
Keep proof and renewal dates. Save licenses, receipts, application confirmations, agency emails, and renewal dates in one folder.

Common Delaware mistakes

Thinking Delaware has no business license because it has no sales tax. Delaware has no state or local sales tax, but it does have a state business license and gross receipts tax system.
Forming a Delaware LLC and stopping there. Entity formation is not the same as a Division of Revenue business license.
Skipping local licensing. Wilmington, Newark, Dover, Middletown, New Castle, and other local governments may have their own rules.
Using a trade name without checking Delaware’s current process. Delaware moved new trade name registration to the Division of Revenue and One Stop effective February 2, 2026.
Ignoring zoning before signing a lease. A landlord may allow your business, but the zoning office still controls whether the use is allowed at that address.
Assuming a professional license replaces the state business license. Delaware DPR says a professional license is not the same as a Division of Revenue business license.
Opening a food or alcohol business before agency review. Health, alcohol, fire, building, and local approvals can affect your location, layout, equipment, and timing.
Forgetting separate activities. Delaware says a separate license is required for each separate business activity.

What to ask when you contact the agency

Before calling or emailing, have your business type, legal name, trade name, address or service area, ownership structure, employee plan, and products or services ready. If you do not have a location yet, say that clearly.

Phone or email script

Hello. I am starting a [business type] in [city or county], Delaware. The business will be [home-based / mobile / storefront / online / service-based] and will [describe products or services]. I want to confirm which Delaware state license, trade name registration, gross receipts tax account, employer registration, zoning approval, local business license, or industry permit I should check before opening. Can you tell me which office handles this, what the official application page is, and whether I should contact another agency before applying?

If the first office cannot answer everything, ask which office to contact next. Business licensing often crosses more than one agency.

Write down the agency name and staff member name if provided.
Write down the license, permit, registration, or approval name.
Ask whether the rule applies to your exact location and business activity.
Ask for the official application link or fee page.
Ask whether zoning, building, fire, health, or professional review must happen first.
Ask whether renewals are annual, multi-year, or tied to a calendar year.
Save the date, answer, and link in your business records.

What to do next

If you are just starting, begin with the state license and location questions. Do not wait until the end to check zoning or industry permits.

Use Delaware One Stop to identify the state license path for your business activity.
If forming an LLC or corporation, check the Delaware Division of Corporations before you submit tax and license applications.
If using a business name that is not your legal name, review Delaware’s trade name process.
Call or email the city, town, or county where the business will be located or where work will be performed.
Contact the industry agency before you spend money on a food space, liquor concept, professional practice, construction job, pesticide work, nursery business, or regulated facility.
Keep copies of every confirmation, license, permit, email, receipt, renewal notice, and inspection result.
