Introduction: Quick Recommendation
An LLC is the stronger choice for most Delaware businesses. You'll pay $110 to file with the Delaware Division of Corporations (6 Del. C. § 18-201), plus $300 annually in franchise tax due June 1 (6 Del. C. § 18-1107), but you gain personal liability protection—something a DBA cannot provide. A DBA costs less upfront (county filing fees only, typically $10–$50) but leaves your personal assets fully exposed to business debts and lawsuits.
The critical difference: An LLC separates your personal and business liability under Delaware law (6 Del. C. § 18-303). A DBA offers zero liability shield. If you're operating with minimal risk or as a side venture, a DBA may suffice. If you have employees, significant assets, or professional liability exposure, an LLC is essential.
FAQ: Three Practical Comparison Questions
Question 1: What's the actual cost difference in year one?
LLC: $110 filing fee + $300 annual franchise tax (due June 1 following formation) = $410 minimum in year one (6 Del. C. § 18-201, § 18-1107). If you elect expedited processing, add $50 (24-hour), $100 (same-day), $500 (2-hour), or $1,000 (1-hour). You may also need a registered agent if you don't serve yourself—budget $100–$300 annually for a third-party agent (6 Del. C. § 18-104).
DBA: County prothonotary filing fee only, typically $10–$50 depending on which Delaware county you operate in. No annual renewal required. Year-one cost: $10–$50.
Reality check: The LLC costs 8–40 times more upfront, but the DBA offers zero liability protection. One lawsuit could wipe out your personal savings. The $360 difference is insurance against personal asset seizure.
Question 2: Do I have to pay Delaware income tax on my business profits?
LLC: Delaware imposes a graduated personal income tax of 2.2%–6.6% on LLC members' distributive shares (passed through to members' personal returns). This applies only to income earned within Delaware. If your LLC earns income entirely outside Delaware, you owe no Delaware income tax on that income. You also owe the $300 annual franchise tax regardless of profitability (6 Del. C. § 18-1107). Additionally, if your business operates in Delaware, you may owe gross receipts tax (approximately 0.0945%–1.9914% depending on industry).
DBA: As a sole proprietor, you pay the same 2.2%–6.6% graduated personal income tax on net business income earned in Delaware, plus gross receipts tax if applicable. You do not pay a franchise tax (that's an LLC-specific fee). Self-employment tax applies to both structures.
Bottom line: Tax burden is roughly equivalent, but the LLC adds the $300 franchise tax. The DBA has no franchise tax but offers no liability shield.
Question 3: What happens if I don't file my annual tax payment on time?
LLC: The $300 annual franchise tax is due June 1 each year (6 Del. C. § 18-1107). If you miss the deadline, you face a $200 penalty plus 1.5% monthly interest on the unpaid tax and penalty combined. There is no grace period. If your annual tax remains unpaid for 3 consecutive years, your Certificate of Formation is automatically canceled, and your LLC dissolves (6 Del. C. § 18-1108). You can file a Certificate of Revival to reinstate, but you must pay all delinquent taxes and penalties first.
DBA: No annual filing or tax payment is required to maintain the DBA registration. However, you still owe Delaware income tax and gross receipts tax on your business income—those are separate obligations to the Division of Revenue, not tied to the DBA filing itself.
Implication: An LLC requires active compliance; a DBA is passive once filed.

Formation Cost and Process
An LLC requires filing a Certificate of Formation with the Delaware Division of Corporations (6 Del. C. § 18-201). The document must include the LLC's name (with required designator "LLC," "L.L.C.," or "Limited Liability Company"), the street address of a registered office in Delaware, and the name of a registered agent at that address (6 Del. C. § 18-104). You can file online at https://icis.corp.delaware.gov/eCorp/ or by mail. The standard filing fee is $110, with processing in 2–3 business days. If you need faster processing, Delaware offers expedited options: 24-hour (+$50), same-day (+$100), 2-hour (+$500), or 1-hour (+$1,000)—all in addition to the base $110 fee.
You can reserve an LLC name for $75 for 120 days before filing, using the name search tool at https://icis.corp.delaware.gov/Ecorp/EntitySearch/NameSearch.aspx. Your chosen name must be distinguishable on the Division's records and cannot include restricted words like "Bank," "University," or "Insurance" (6 Del. C. § 18-102).
A registered agent must be a Delaware resident individual or a domestic/foreign entity authorized to do business in Delaware (6 Del. C. § 18-104). A member can serve as registered agent. If you hire a third-party agent, expect to pay $100–$300 annually. The agent must consent to serve and maintain a physical Delaware address.
An operating agreement is not legally required (6 Del. C. § 18-101(9)), but Delaware law applies statutory defaults if you don't have one—members manage by default, profits and losses split equally, and maximum freedom of contract applies (6 Del. C. § 18-1101(b)). Most attorneys recommend a written agreement to clarify member roles, profit distribution, and dispute resolution.
Important: Even after forming an LLC, you must file a DBA (Doing Business As) certificate with the county prothonotary in each Delaware county where you operate. This is a separate filing from the LLC formation and is required by Delaware law.
A DBA requires only a county-level filing with the prothonotary's office. You provide your business name, your personal name, and the address where you'll operate. The fee is typically $10–$50 depending on the county. There is no state-level DBA filing in Delaware; it's purely a county matter. No annual renewal is required. The DBA is filed under your personal name, so it offers no privacy.
Tax Treatment Differences
Delaware imposes a graduated personal income tax of 2.2% to 6.6% on residents' income, including business income. For an LLC, this tax applies to each member's distributive share of LLC profits, whether or not the profits are actually distributed. The LLC itself does not pay Delaware income tax; the tax passes through to members' personal returns. Importantly, if an LLC earns income entirely outside Delaware, that income is not subject to Delaware income tax—a significant advantage for remote or multi-state operations.
In addition to income tax, every Delaware LLC must pay a $300 annual franchise tax (6 Del. C. § 18-1107), due June 1 each year. This is a flat fee regardless of profitability or revenue. If you form a Series LLC (a special Delaware structure allowing separate series with independent liability), each registered series owes an additional $75 per series. The franchise tax is due even if the LLC is inactive or unprofitable.
If your LLC operates a business in Delaware, you may also owe gross receipts tax, which varies by industry and is approximately 0.0945% to 1.9914% of gross receipts. Delaware has no sales tax, but gross receipts tax applies to many service and retail businesses operating within the state.
For federal tax purposes, a single-member LLC is treated as a disregarded entity by default—you report business income on Schedule C of your personal Form 1040, just like a sole proprietor. A multi-member LLC is treated as a partnership by default and files Form 1065 with Schedule K-1s to members. You can elect S-Corp or C-Corp status if it reduces your overall tax burden.
A DBA sole proprietor pays the same 2.2%–6.6% Delaware income tax on net business income and the same gross receipts tax if operating in Delaware. However, the sole proprietor does not pay the $300 LLC franchise tax. Self-employment tax (15.3% on 92.35% of net earnings) applies to both LLCs and DBAs, though an S-Corp election can reduce self-employment tax for both structures.
Tax example: A Delaware LLC earning $100,000 in Delaware-sourced income with one member pays approximately $6,600 in state income tax (at the top 6.6% rate) plus $300 franchise tax = $6,900 total state tax. A DBA sole proprietor earning the same $100,000 pays approximately $6,600 in state income tax but no franchise tax = $6,600 total state tax. The LLC costs $300 more annually in franchise tax but provides liability protection the DBA does not.
Liability and Asset Protection
This is the defining difference between an LLC and a DBA.
An LLC provides personal liability protection under 6 Del. C. § 18-303. Members are not personally liable for the LLC's debts, obligations, or liabilities, nor for the negligence or misconduct of other members or employees. If the LLC is sued or owes money, creditors can pursue only the LLC's assets, not your personal bank account, home, or investments. This protection applies even if you are the sole member.
However, liability protection is not absolute. You remain personally liable for your own negligence or misconduct, and creditors can "pierce the corporate veil" if the LLC is underfunded, commingled with personal finances, or used fraudulently. To maintain protection, keep business and personal finances separate, maintain adequate insurance, and follow basic LLC formalities (though Delaware is lenient on formalities).
Delaware LLCs also offer strong charging order protection (6 Del. C. § 18-703). If a creditor obtains a judgment against you personally, they cannot seize your membership interest in the LLC. Instead, they can only obtain a "charging order," which entitles them to distributions if the LLC makes them—but they cannot vote, manage, or force dissolution. This is a powerful asset protection feature.
A DBA offers zero liability protection. You are a sole proprietor, and your personal assets are fully exposed. If your business is sued, injures someone, or owes money, creditors can pursue your personal bank accounts, home, car, and investments. There is no legal separation between you and the business. If you operate under a DBA and face a $500,000 lawsuit, your personal assets are at risk.
Practical scenario: You operate a consulting business. A client sues you for $250,000 in damages. If you're an LLC, the lawsuit targets the LLC's assets only; your personal home and savings are protected. If you're a DBA, the judgment can be enforced against your personal assets, potentially forcing bankruptcy.
For any business with employees, significant assets, or professional liability exposure, an LLC is essential. For a low-risk, part-time venture with minimal assets, a DBA may be acceptable—but insurance becomes critical.
Management and Compliance
An LLC offers maximum management flexibility. By default, an LLC is member-managed, meaning all members participate in day-to-day decisions (6 Del. C. § 18-301 et seq.). You can instead elect manager-managed status, where designated managers (who may or may not be members) run the business while members are passive investors. Delaware law gives LLCs "maximum effect to freedom of contract" (6 Del. C. § 18-1101(b)), so your operating agreement can customize voting rights, profit distribution, decision-making authority, and dispute resolution however you wish.
An operating agreement is optional but strongly recommended. If you don't have one, Delaware's statutory defaults apply: member-managed, equal profit/loss sharing, and default rules for admission, withdrawal, and dissolution. A written agreement clarifies roles, prevents disputes, and is essential for multi-member LLCs.
Compliance burden for an LLC:
- Annual franchise tax payment due June 1 each year ($300 flat fee). Failure to pay results in a $200 penalty plus 1.5% monthly interest, and automatic dissolution after 3 years of non-payment (6 Del. C. § 18-1108).
- Registered agent maintenance—your agent must remain a Delaware resident or authorized entity with a physical Delaware address.
- DBA filing in each county where you operate (separate from LLC formation).
- Operating agreement (optional but recommended).
- No annual report to the Division of Corporations is required for LLCs (unlike corporations).
A DBA sole proprietor has minimal compliance burden. Once filed with the county prothonotary, the DBA requires no annual renewal, no tax payments to maintain it, and no registered agent. However, you still owe Delaware income tax and gross receipts tax to the Division of Revenue—those are separate obligations. You must also obtain a state business license from the Delaware Division of Revenue if you operate in Delaware, and any professional or industry-specific licenses (health permits, professional licenses, etc.).
Transferability: An LLC membership interest can be transferred to another
