Delaware Foreign LLC Registration Guide

1. What is a foreign LLC in Delaware?

In Delaware, the term foreign LLC does not refer to an international business. Instead, it describes a limited liability company that was originally formed outside Delaware, either in another U.S. state or in a foreign country, and now plans to operate within Delaware.

To legally conduct business in the state, an out-of-state company must complete a Delaware foreign LLC registration. Once approved, Delaware grants the LLC formal authority to operate, commonly referred to as a Certificate of Authority. The official filing document used for this process is the Foreign Limited Liability Company Application for Registration.

2. When is Delaware foreign LLC registration required?

You are generally required to complete a Delaware foreign LLC registration if your business activities qualify as transacting business within the state. While Delaware does not provide a single comprehensive definition, common indicators include the following:

• Maintaining an office, warehouse, storefront, or other physical presence in Delaware
• Hiring employees or long-term contractors who are based in Delaware
• Regularly performing services or executing contracts within the state
• Owning or leasing real estate or operational assets located in Delaware

Activities that may not require registration

Like most states, Delaware allows certain limited activities without triggering foreign registration, such as holding internal company meetings, maintaining a bank account, or completing isolated transactions. If your business maintains ongoing operational ties to Delaware, registration is strongly recommended.

6. How to complete Delaware foreign LLC registration (step-by-step)

Step 1: Confirm your LLC is active and in good standing

Before starting your Delaware foreign LLC registration, confirm that your LLC is active and compliant in its formation state. While Delaware does not always require a Certificate of Good Standing to be submitted with the filing, banks, landlords, and business partners frequently request proof that your LLC is valid and in good standing.

Step 2: Reserve your Delaware business name

Delaware allows foreign LLCs to reserve a business name using a Certificate of Name Reservation , but this step is optional and not required to file the foreign registration application. If your exact legal name is unavailable in Delaware, you must reserve an approved alternate or Delaware use name.

Step 3: Appoint a Delaware registered agent

Your foreign LLC must designate a Delaware registered agent with a physical street address located within the state. The registered agent must be available during normal business hours to receive legal documents and official notices on behalf of your company.

Step 4: File the Foreign LLC Application for Registration

Submit the Foreign Limited Liability Company (LLC) Application for Registration with the Delaware Secretary of State. This filing formally authorizes your out-of-state LLC to transact business in Delaware and results in the issuance of a Certificate of Authority.

• Enter your LLC’s legal name and Delaware use name, if applicable
• Attach the approved Certificate of Name Reservation
• Provide principal office and mailing addresses
• List your Delaware registered agent and registered office address
• State the date your LLC began or will begin business activities in Delaware

7. After approval: taxes, licenses, and banking

A) Delaware tax obligations

After completing your Delaware foreign LLC registration, your business may have ongoing Delaware tax responsibilities. Delaware does not impose a traditional franchise tax on LLCs. Instead, tax obligations depend on how your LLC is classified for federal tax purposes.

Eligible LLCs may elect to pay Delaware’s Pass-Through Entity Tax (PET) , which is paid at the entity level and allows members to claim corresponding credits on their Delaware personal income tax returns. Single-member LLCs and disregarded entities may follow different reporting rules.

In addition to foreign registration, your business may be required to obtain state or local business licenses. Licensing requirements vary based on location and business activity, such as retail, professional services, construction, or regulated industries.

C) EIN and business banking

Delaware foreign LLC registration does not create a new legal entity, so most LLCs continue using their existing EIN. However, banks and payment processors often request updated documentation, including:

• Delaware Certificate of Authority
• Operating Agreement
• EIN confirmation letter from the IRS (IRS EIN resource)
• Identification for owners or authorized signers
