Delaware LLC Formation: Key Facts at a Glance

How to Start an LLC in Delaware: Step-by-Step

Step 1: Choose a Name for Your Delaware LLC

Your LLC name must be distinguishable from any existing business entity registered with the Delaware Division of Corporations. Delaware requires that your name include “Limited Liability Company,” “LLC,” or “L.L.C.” — abbreviations are acceptable in most cases.

Before settling on a name, search the Delaware Division of Corporations’s business entity database to confirm availability. If your desired name is taken, you’ll need to choose a different one or modify it enough to be considered distinguishable. Consider also checking domain name availability and social media handles before finalizing your choice.

You can reserve your LLC name for a limited period (typically 120 days) by filing a name reservation with the Delaware Division of Corporations if you’re not ready to file your Certificate of Formation immediately.

Step 2: Appoint a Registered Agent in Delaware

Every Delaware LLC must designate a registered agent — a person or company authorized to receive legal documents, government notices, and service of process on behalf of your LLC. Your registered agent must have a physical street address in Delaware (P.O. boxes are not acceptable) and be available during normal business hours.

You have three options for your registered agent:

• Yourself — You can serve as your own registered agent if you have a physical address in Delaware and are available during business hours. This is free but means your home address becomes public record.
• A friend or family member — Any adult resident of Delaware can serve as your registered agent.
• A professional registered agent service — Companies like Northwest Registered Agent ($125/year) or ZenBusiness ($199/year) provide registered agent services in all 50 states. This is the most popular option because it keeps your home address off public records and ensures reliable service.

Step 3: File Your Certificate of Formation with the Delaware Division of Corporations

The Certificate of Formation is the official document that creates your LLC in Delaware. You file this with the Delaware Division of Corporations. The filing fee is $110 and standard processing takes 10 business days.

Your Certificate of Formation typically requires the following information:

• LLC name (must include “LLC” or “Limited Liability Company”)
• Registered agent name and Delaware street address
• Principal office address
• Organizer’s name and signature
• LLC’s purpose (a general statement is typically acceptable)
• Management structure (member-managed or manager-managed)
• Effective date (can be future-dated in some states)

Most states allow online filing, which is typically faster than mail filing. After your Certificate of Formation is processed and approved, you’ll receive a stamped or certified copy confirming your LLC’s existence.

Step 4: Create an Operating Agreement

An operating agreement is an internal document that outlines your LLC’s ownership structure, management rules, profit distribution, and procedures for adding or removing members. While Delaware requires an operating agreement, creating one is essential for every LLC — even single-member LLCs.

Your operating agreement should cover:

• Ownership percentages and capital contributions of each member
• How profits and losses are distributed among members
• Management structure and voting rights
• Procedures for adding new members or handling member departures
• Process for dissolving the LLC
• Meeting requirements and record-keeping responsibilities

Without an operating agreement, your LLC will default to Delaware’s LLC Act provisions, which may not align with your intentions. Banks, investors, and potential partners may also request to see your operating agreement before doing business with your LLC.

Step 5: Get an EIN (Employer Identification Number)

An EIN is a nine-digit number assigned by the IRS that functions as your LLC’s tax identification number — essentially a Social Security number for your business. You need an EIN to open a business bank account, hire employees, file federal taxes, and establish business credit.

Getting an EIN is free and takes about five minutes:

• Online — Apply at IRS.gov (available Monday–Friday, 7 AM–10 PM ET). You’ll receive your EIN immediately upon completion.
• By mail — Submit Form SS-4 to the IRS. Processing takes 4-5 weeks.
• By fax — Fax Form SS-4 to the IRS. Processing takes about 4 business days.

Step 6: Open a Business Bank Account

Opening a separate business bank account is critical for maintaining the limited liability protection your LLC provides. Mixing personal and business finances — known as “commingling” — can lead to a court “piercing the corporate veil,” which means your personal assets could be exposed to business liabilities.

To open a business bank account, you’ll typically need:

• Your approved Certificate of Formation (certified copy)
• EIN confirmation letter from the IRS
• Operating agreement
• Government-issued photo ID for all signers

Compare business checking accounts from multiple banks. Look for accounts with no or low monthly fees, free incoming transfers, and integration with accounting software like QuickBooks or Xero.

Delaware-Specific Requirements

Delaware is the most popular state for business formation due to its business-friendly laws, Court of Chancery, and strong LLC protections. The annual tax for LLCs is a flat $300 due by June 1 each year. There is no publication requirement. If you’re forming a Delaware LLC but operating in another state, you’ll need to foreign qualify in your home state as well, which means additional fees.

Delaware LLC Taxes

Delaware charges a flat $300 annual LLC tax due by June 1 each year. Delaware has no state sales tax. If your LLC operates outside Delaware, you generally won’t owe Delaware income tax on that income. Delaware’s Court of Chancery provides specialized business law expertise.

Regardless of your state tax situation, all LLCs must comply with federal tax obligations. By default, single-member LLCs are taxed as disregarded entities (reported on your personal return via Schedule C), and multi-member LLCs are taxed as partnerships (filing Form 1065). You can also elect to have your LLC taxed as an S-Corp or C-Corp by filing the appropriate forms with the IRS — consult a tax professional to determine which classification saves you the most money.

Should You Use a Formation Service or File Yourself?

Filing your Delaware LLC yourself through the Delaware Division of Corporations’s website is straightforward and costs only the state filing fee ($110). If you’re comfortable with basic government forms and want to save money, DIY formation is a perfectly valid option.

However, a formation service can be worthwhile if you want to save time, avoid paperwork mistakes, and get additional features like compliance alerts, operating agreement templates, and registered agent service bundled together. Services like Northwest Registered Agent ($39 + state fees) and ZenBusiness ($0 + state fees) handle the entire filing process and can include a year of registered agent service.

For most first-time LLC owners, using a formation service provides peace of mind that everything is filed correctly while adding compliance tools that help you stay on top of ongoing requirements.
