What You Need to Start a Business in Delaware
Delaware's business-friendly legal framework, Court of Chancery, and zero sales tax make it one of the most popular states for incorporation in the country. The Delaware Division of Corporations handles all entity filings and charges $110 to form an LLC online.
You will also need a registered agent with a physical Delaware address, a federal EIN from the IRS, and a Delaware business license from the Division of Revenue. This guide covers every requirement in order so nothing falls through the cracks.
Validate Your Business Idea
Test your business concept against Delaware's strongest economic sectors before investing. The state's top industries include:
- Financial services and banking (Wilmington is the credit card capital of the U.S.)
- Chemical and pharmaceutical manufacturing
- Technology and e-commerce startups

Write a Business Plan
A written business plan is required for SBA loans and most bank financing. Include your revenue model, target market, startup costs, and 12-month financial projections.
Use our business plan guide to build a lean, investor-ready document in a few hours. Even if you are not seeking funding, the exercise forces you to stress-test your assumptions before spending money.
Pro Tip
Choose Your Business Structure in Delaware
Most founders in Delaware choose an LLC because it combines liability protection with pass-through taxation and minimal paperwork. Filing an LLC costs $110 at the Delaware Division of Corporations.
The four main structures are sole proprietorship, LLC, S-Corp, and C-Corp. Delaware's Court of Chancery and well-established case law make it especially popular for C-Corps seeking venture capital. See the full comparison below, or read our Delaware LLC formation guide for a deeper look.

Business Structure Comparison — Delaware
Full comparison guide| Structure | Delaware Filing Cost | Personal Liability | How You're Taxed | Best For |
|---|---|---|---|---|
| Sole Proprietorship | $75 (DBA) | ❌ None | Personal income tax. No separate return. | Freelancers, consultants, side hustles testing an idea with no employees. |
| LLC Most Common | $110 online | ✅ Personal assets protected | Pass-through by default. Elect S-Corp when profitable. | Most small businesses. Best balance of liability protection, flexibility, and tax options. |
| S-Corporation | ~$110 + IRS election | ✅ Personal assets protected | Pass-through. Owners pay themselves a salary — can reduce self-employment tax. | Profitable businesses (typically $50K+ net) where payroll tax savings justify the complexity. |
| C-Corporation | $89 | ✅ Personal assets protected | Corporate tax rate (21% federal). Double taxation on dividends. | Startups planning to raise VC funding, issue stock options, or eventually go public. |
| General Partnership | Free / No State Filing | ❌ None — all partners personally liable | Pass-through. Each partner reports share on personal return. | Two or more owners who trust each other and don't need liability protection. |
Which should you choose? Most first-time founders in Delaware pick an LLC — it protects your personal assets without the complexity of a corporation. If you're not sure, consult a CPA or business attorney before filing. Read the full Delaware LLC guide →
Choose and Register Your Business Name
Search the Delaware Entity Search to confirm your desired name is available. Your LLC name must include "LLC," "L.L.C.," or "Limited Liability Company" as a designator.
Reserve a name for $75 if you are not ready to file yet. If you plan to operate under a different name, file a trade name (DBA) with the county Prothonotary office for $25 to $75.
Pro Tip
Check Delaware Business Name Availability
Search the official Delaware Division of Corporations database before you file.
Register Your Business with the State
File your Certificate of Formation with the Delaware Division of Corporations online for $110. Standard processing takes 3 to 5 business days, and expedited 24-hour service is available for an additional $50 to $100.
You must designate a registered agent with a physical Delaware address in your filing. See our Delaware registered agent guide for affordable options starting around $50 per year.
After approval, you will receive a stamped Certificate of Formation. Keep this document safe because banks and licensing agencies will request a copy.

Get Your Federal EIN

- Delaware Business License — required for virtually all businesses; apply through the Division of Revenue for $75 (fees range from $50 to $500 depending on business type)
- Gross Receipts Tax Registration — Delaware has no sales tax but imposes a gross receipts tax; register with the Division of Revenue
- Professional License — required for contractors, healthcare providers, real estate agents, and other regulated fields through the Division of Professional Regulation
- Employer Registration — required before hiring; register for withholding tax and unemployment insurance at the Delaware Department of Labor
Pro Tip
Open a Business Bank Account
Bring your EIN confirmation letter, Certificate of Formation, government-issued ID, and LLC operating agreement to open your account. Separating business and personal finances is essential to maintaining your LLC's liability protection.

Pro Tip
Set Up Accounting and Understand Your Taxes
Delaware has no sales tax, but it does impose a gross receipts tax ranging from 0.0945% to 1.9914% depending on your business activity. The state income tax for individuals is graduated from 2.2% to 6.6%, and LLCs taxed as pass-throughs will pay at individual rates.
