LLC vs PLLC in Delaware (2026)

Introduction

If you're a licensed professional in Delaware—attorney, accountant, physician, or engineer—you must choose between an LLC and a Professional LLC (PLLC). Both entities offer liability protection and pass-through taxation, but a PLLC carries mandatory professional insurance and stricter governance rules tied to your license. For most professionals, a PLLC is legally required by your licensing board, not optional. If you're not a regulated professional, form an LLC instead—it costs the same to file ($110) but gives you more operational flexibility without professional compliance overhead.

FAQ: Three Practical Comparison Questions

Q1: Do I have to form a PLLC, or can I use an LLC?

Your licensing board decides. Delaware law permits PLLCs under 6 Del. C. § 18-102, but professional licensing statutes (Delaware Board of Medical Licensure, Delaware State Bar, etc.) often mandate PLLC formation for regulated practitioners. Check your specific license requirements before filing. If you're not licensed, you cannot form a PLLC—only an LLC.

Q2: Will forming a PLLC cost me more than an LLC?

No. Both file a Certificate of Formation with the Delaware Division of Corporations at $110 (6 Del. C. § 18-201). Both pay the same $300 annual franchise tax (6 Del. C. § 18-1107). The cost difference appears in professional liability insurance (required for PLLCs, optional for LLCs) and compliance labor—PLLCs must maintain detailed records of professional conduct and insurance coverage.

Q3: Which entity protects my personal assets better?

Both offer strong liability protection under Delaware law. An LLC member's personal assets are protected from business debts under 6 Del. C. § 18-703 (charging order protection). A PLLC offers the same protection, but with one critical exception: professional malpractice claims pierce the liability shield. Your personal assets remain at risk for your own negligence, even in a PLLC. Non-professional debts stay protected in both structures.

Formation Cost and Process

Both LLC and PLLC formation in Delaware follows the same filing pathway. You submit a Certificate of Formation to the Delaware Division of Corporations (6 Del. C. § 18-201) with three required contents: (1) the entity name (must include "LLC," "L.L.C.," or "Limited Liability Company"), (2) the street address of your registered office in Delaware, and (3) the name of your registered agent at that address.

Filing Fees

Certificate of Formation: $110 (both LLC and PLLC)
Expedited processing: +$50 (24-hour), +$100 (same-day), +$500 (2-hour), +$1,000 (1-hour)
Standard processing: 2–3 business days

Name Registration

If you want to reserve your name before filing, pay $75 for a 120-day reservation (6 Del. C. § 18-102). Your name must be distinguishable on the Division of Corporations records and cannot include restricted words like "Bank," "University," or "Insurance" without special approval.

Registered Agent Requirement

Both structures require a registered agent with a physical Delaware address. Your registered agent can be an individual Delaware resident, a domestic corporation, or an LLC (including yourself, if you're a Delaware resident). Changing your registered agent costs $50 and requires the agent's written consent (6 Del. C. § 18-104).

DBA Filing

If you operate under a name different from your LLC or PLLC name, you must file a DBA with the County Prothonotary in each Delaware county where you conduct business. This is a separate filing outside the Division of Corporations.

Timeline to Operation

Standard formation takes 2–3 business days. You can choose an effective date in the future (6 Del. C. § 18-201). Most professionals file on Monday and operate by Wednesday.

Tax Treatment Differences

Delaware taxes LLCs and PLLCs identically at the entity level. The difference lies in how your members' personal tax liability flows through.

Federal Taxation

Single-member LLC: Disregarded entity (you report income on Schedule C of Form 1040)
Multi-member LLC: Partnership (Form 1065 with Schedule K-1 to each member)
Single-member PLLC: Disregarded entity (Schedule C)
Multi-member PLLC: Partnership (Form 1065 with Schedule K-1)

Both can elect S-corp or C-corp taxation if it reduces self-employment tax or provides other advantages.

Delaware State Taxes

Franchise Tax: $300 annual flat tax for all domestic and foreign LLCs and PLLCs (6 Del. C. § 18-1107). Due June 1 each year. First payment due June 1 of the year following formation. If you miss the deadline, you owe a $200 penalty plus 1.5% monthly interest on the tax and penalty. After 3 years of non-payment, your Certificate of Formation is automatically canceled (6 Del. C. § 18-1108).

Personal Income Tax: Delaware imposes graduated personal income tax at rates of 2.2%–6.6% on LLC and PLLC members' share of pass-through income (6 Del. C. § 30-3101 et seq.). This applies only to income earned in Delaware. If your LLC earns income entirely outside Delaware, no Delaware state income tax applies.

Gross Receipts Tax: Businesses operating in Delaware pay gross receipts tax at rates varying by industry (approximately 0.0945%–1.9914%). This applies to both LLCs and PLLCs. Delaware has no sales tax.

Self-Employment Tax

Both LLC and PLLC members pay self-employment tax on their distributive share of net earnings (15.3% combined Social Security and Medicare). An S-corp election can reduce this burden by allowing you to pay yourself a reasonable W-2 salary and take the remainder as a distribution (not subject to self-employment tax).

Estimated Tax Deadlines

April 15, June 15, September 15, and January 15 (federal and state).

Liability and Asset Protection

Delaware law provides strong liability protection for both LLCs and PLLCs, but with a critical distinction for professionals.

Charging Order Protection

Under 6 Del. C. § 18-703, a creditor of an LLC member cannot seize the member's ownership interest or force a distribution. The creditor's only remedy is a "charging order," which entitles the creditor to receive distributions if and when the LLC makes them—but the creditor cannot force distributions or vote on LLC matters. This protection applies equally to LLC and PLLC members for non-professional debts.

Professional Malpractice Exception

A PLLC does not shield a member from personal liability for their own professional negligence. If you're a physician in a PLLC and commit medical malpractice, the injured patient can sue you personally and recover your personal assets. The PLLC structure protects you from liability for other members' malpractice (if you have partners), but not your own. An LLC offers no professional liability protection either, because non-professionals cannot form PLLCs.

Non-Professional Debt Protection

Both structures protect members from business debts unrelated to professional services. If your LLC or PLLC defaults on a lease, loan, or vendor payment, creditors cannot pursue your personal assets—only the entity's assets.

Professional Liability Insurance

PLLCs must carry professional liability insurance as a condition of licensure (requirements vary by profession and licensing board). This insurance, not the PLLC structure, is your primary protection against malpractice claims. An LLC is not required to carry professional liability insurance, but many professionals purchase it voluntarily.

Management and Compliance

Operating Agreement

Neither an LLC nor a PLLC requires a written operating agreement under Delaware law (6 Del. C. § 18-101(9)). If you don't adopt one, statutory default rules apply: the entity is member-managed, profits and losses are shared equally among members, and the agreement may be written, oral, or implied. However, most professionals adopt a written operating agreement to clarify roles, profit splits, and exit procedures.

Management Structure

An LLC can be member-managed (all members participate in decisions) or manager-managed (designated managers run the business). A PLLC must follow the governance rules set by your professional licensing board. Most licensing boards require that only licensed professionals can be managers or members, and that the entity be member-managed (not delegated to non-licensed managers).

Compliance Burden

LLC: File the Certificate of Formation ($110), pay the annual $300 franchise tax by June 1, and maintain basic business records. If you operate under a DBA, file it with the County Prothonotary. No professional licensing compliance required.

PLLC: File the Certificate of Formation ($110), pay the annual $300 franchise tax by June 1, maintain professional liability insurance, keep detailed records of professional conduct, comply with your licensing board's continuing education requirements, and report any disciplinary actions or insurance claims to the board. Compliance labor is significantly higher.

Annual Reporting

Delaware does not require an annual report for LLCs or PLLCs. You only pay the $300 annual franchise tax by June 1. Corporations, by contrast, must file an annual report ($50 fee) by March 1.

Dissolution

To dissolve an LLC or PLLC, file a Certificate of Cancellation with the Division of Corporations ($220 filing fee). You must pay all taxes owed, including the full annual franchise tax for the cancellation year, before the Division accepts the cancellation (6 Del. C. § 18-1107(c)). Wind up the entity's affairs under 6 Del. C. §§ 18-803/18-804, pay debts, and distribute remaining assets per your operating agreement.

Which Structure Is Right for Your Situation

Form an LLC if

You are not a licensed professional (or your profession is not regulated)
You want maximum operational flexibility without licensing board oversight
You want to minimize compliance labor and cost
You operate a business where liability protection for non-professional debts is your primary concern
You plan to raise capital from non-professional investors

Form a PLLC if

Your professional licensing board requires or permits PLLC formation (check your board's rules)
You are a physician, attorney, accountant, engineer, or other regulated professional
You want to signal to clients and regulators that you operate under professional standards
You have partners and want protection from their malpractice (though not your own)
Your licensing board mandates professional liability insurance (which you'll carry regardless of entity type)

Decision Framework

Check your licensing board's requirements. If your board mandates PLLC formation, the choice is made for you. If your board permits both LLC and PLLC, proceed to step 2.
Assess your liability exposure. If your primary risk is professional malpractice, a PLLC offers no additional protection beyond what professional liability insurance provides. If your risk is non-professional debt (loans, leases, vendor disputes), both LLC and PLLC protect you equally.
Calculate compliance cost. An LLC costs $110 + $300/year. A PLLC costs $110 + $300/year + professional liability insurance (typically $500–$5,000/year, depending on profession) + compliance labor. If your licensing board requires PLLC formation, this cost is unavoidable.
Consider signaling and credibility. Some clients and referral sources view PLLC formation as a mark of professionalism and regulatory compliance. If this matters in your market, form a PLLC. If not, an LLC is sufficient.

Conclusion

In Delaware, LLC and PLLC formation costs are identical ($110 filing fee, $300 annual franchise tax), and both offer strong liability protection for non-professional debts. The choice hinges on whether you are a licensed professional and whether your licensing board requires PLLC formation.

For non-professionals: Form an LLC. You get liability protection, pass-through taxation, and operational flexibility without professional compliance overhead.

For licensed professionals: Check your licensing board's rules. If PLLC formation is required or permitted, form a PLLC to comply with regulatory expectations and signal professionalism to clients. If your board permits LLC formation, an LLC is legally sufficient, but verify this with your board before filing.

For professionals with partners: A PLLC protects you from your partners' malpractice but not your own. Professional liability insurance, not the entity structure, is your primary protection against malpractice claims. Both LLC and PLLC offer equal protection for non-professional debts.
