Delaware LLP: Formation, Annual Tax, and Liability Shield

A Delaware limited liability partnership is formed by filing a Statement of Qualification with the Delaware Secretary of State, costs $200 per partner to file, and once effective shields each partner from personal liability for partnership obligations. Keeping that shield means filing an annual report and paying a flat $300 tax by June 1 every year. The rest is detail, but the detail matters: miss a deadline long enough and the state revokes your LLP status, exposing partners personally to debts incurred during the gap.

How You Form a Delaware LLP

The founding document is the Statement of Qualification. It has to list the partnership’s name, the registered office address, the registered agent’s name and address, the number of partners at the time of filing, and a statement that the partnership elects LLP status.¹ If you want the election to take effect on a future date rather than at filing, you specify that date in the document.

The filing fee is $200 per partner, not a flat $200.² A five-partner firm pays $1,000 to file. That per-partner structure makes Delaware LLP formation meaningfully more expensive for larger partnerships than forming an LLC with a single flat fee.

The partnership name must end with “Limited Liability Partnership,” “L.L.P.,” or “LLP,” and it must be distinguishable from other entities already registered in Delaware. Run a name availability search through the Division of Corporations before filing.

Registered Agent and Office

Every Delaware LLP must maintain a registered office and registered agent in the state. The agent accepts service of process and other legal documents on the partnership’s behalf. Eligible agents include a Delaware resident, a domestic corporation, an LLC, another partnership, or a statutory trust. The registered office is simply the agent’s business address and does not need to be where the partnership actually operates.³ A virtual office or mail-forwarding service alone will not satisfy the requirement. Commercial registered agent services in Delaware typically run between $50 and $199 per year.

Federal EIN

You need a federal Employer Identification Number even if the LLP has no employees, because the IRS requires partnerships to have one for tax filing. Apply using Form SS-4, online for immediate issuance or by mail.⁴

Why You Need a Written Partnership Agreement

Delaware does not require LLPs to have a written partnership agreement, but operating without one is a serious mistake. Without a written agreement, the default rules under the Delaware Revised Uniform Partnership Act fill every gap, and those defaults are rarely what the partners actually want.

Under the defaults, all partners share profits and losses equally regardless of what each contributed, and admitting a new partner requires unanimous consent from every existing partner.¹ Equal sharing almost never matches the deal the partners actually struck, and unanimous consent becomes unworkable once the firm grows past a handful of people.

A workable agreement should at a minimum address:

Capital contributions from each partner and how profits and losses are allocated.
Which partners have authority to bind the partnership on contracts, hiring, and financial commitments.
How new partners are admitted, how departing partners are bought out, and how buyout amounts are calculated.
Which decisions need a majority vote and which require unanimous consent.
What triggers dissolution and how assets are distributed when the partnership winds down.

Delaware courts give enormous weight to the partnership agreement, and it governs the relationship between partners even on issues where the statute would otherwise supply a default. The effort you put into drafting it directly determines how smoothly disagreements get resolved later.

The Annual Report and $300 Tax

Delaware LLPs carry a compliance obligation that LLCs, limited partnerships, and ordinary general partnerships do not: an annual report filed with the Secretary of State. The report lists the partnership’s name, the number of partners, the registered office address, and the registered agent’s name and address. It is due June 1 each year.⁵

The annual tax for all partnership-type entities in Delaware is a flat $300, due on that same June 1 deadline regardless of what the partnership earned.⁶ Missing the deadline triggers a $200 penalty plus 1.5% monthly interest on the unpaid tax and penalty, which compounds quickly if left alone.

What Happens If You Let It Lapse

The real danger of prolonged non-compliance is losing LLP status altogether. If the annual report and fee remain unpaid through June 1 of the following year, the Secretary of State revokes the Statement of Qualification. The partnership does not dissolve, but it loses limited liability protection, and partners become personally liable for partnership obligations going forward. The Secretary of State will also refuse to issue a Certificate of Good Standing for any LLP with an overdue report.⁵

Reinstatement is possible by applying to the Secretary of State and showing the grounds for revocation have been corrected. The gap period still matters, though: during the time LLP status was revoked, partners lacked the shield for obligations the partnership incurred.

Business License and Related Registrations

Beyond the annual report, an LLP operating in Delaware must register with the Division of Revenue for a business license. The state’s One Stop system also handles registration with the Division of Unemployment Insurance and the Office of Workers’ Compensation. Depending on the industry, additional licenses from agencies like the Division of Professional Regulation may apply.⁷

What the Liability Shield Actually Covers

The core benefit of LLP status is that partnership obligations incurred while the election is in effect belong to the partnership alone. A partner is not personally liable for those obligations by contribution, indemnification, assessment, or otherwise, whether the claim sounds in contract, tort, or anything else.⁸ The shield extends to liabilities created by other partners too, so one partner’s malpractice does not reach the personal assets of another.

Several limits are worth knowing before you rely on the shield:

Debts incurred before the Statement of Qualification took effect remain the joint and several responsibility of every partner who was a member at the time.
Partners can voluntarily take on personal liability by contract. Lenders routinely require personal guarantees as a condition of financing, which waives the LLP shield for that specific debt.⁸
A new partner joining an existing partnership is not personally liable for obligations incurred before their admission, regardless of LLP status.
For law firms organized as Delaware LLPs, attorneys’ ability to practice through the LLP is governed by the Rules of the Delaware Supreme Court, not just the partnership statute.

Unlike many other states, Delaware does not require LLPs to carry minimum professional liability insurance or demonstrate financial responsibility to maintain LLP status. That makes Delaware’s statute more permissive than jurisdictions that condition the shield on coverage.

How a Delaware LLP Is Taxed

For federal purposes, an LLP is a pass-through entity. The partnership files an annual information return on Form 1065, and each partner receives a Schedule K-1 reporting their share of income, deductions, gains, losses, and credits. Partners then report those items on their individual returns.⁹ The entity itself pays no federal income tax, avoiding the double taxation that C corporations face.

Self-Employment Tax Catches Many Partners Off Guard

A partner’s distributive share of partnership income is generally subject to self-employment tax, the self-employed equivalent of Social Security and Medicare. There is an exclusion for “limited partners” under Section 1402(a)(13), but the IRS reads it narrowly and does not treat it as automatically available to partners who actively participate in the business, even when they have limited liability.¹⁰

Under the 1997 proposed regulations, which remain the most detailed IRS guidance available, a partner generally fails the “limited partner” test if they can bind the partnership, bear personal liability for partnership debts, or participate for more than 500 hours per year. On top of that, if substantially all the partnership’s activities involve professional services such as law, accounting, medicine, engineering, or consulting, every service-providing partner is treated as non-limited regardless of the other factors. For most professional LLPs, that means each active partner’s full distributive share is subject to self-employment tax. Guaranteed payments for services always are, regardless of partner status.

Delaware State Tax

At the state level, Delaware imposes a flat $300 annual tax on the LLP with no relationship to revenue or profits.⁶ The LLP itself pays no separate Delaware income tax at the entity level. Individual partners who are Delaware residents owe personal income tax on their share of partnership income under the state’s graduated rates, which start at 0% on the first $2,000 of taxable income and reach a top marginal rate of 6.6% on income above $60,000.¹¹ Partners who live elsewhere generally owe tax to their home state rather than Delaware on pass-through income, though the result depends on where the partnership does business and where the partner lives.

Operating Outside Delaware

Forming in Delaware does not authorize the partnership to do business anywhere else. If the LLP maintains a physical office, hires employees, owns or leases property, or holds ongoing contracts requiring regular presence in another state, it will typically need to register as a foreign LLP there. Selling online to customers without a physical presence, attending conferences, and isolated transactions usually do not trigger foreign qualification.

Foreign qualification generally involves filing registration paperwork with the other state’s Secretary of State, paying a one-time fee (commonly $125 to $250), and providing a Delaware Certificate of Good Standing. Operating in another state without registering can bring penalties, loss of the ability to sue in that state’s courts, and liability exposure. Each additional state also adds its own ongoing compliance and fees.

Ending or Reinstating the LLP

When the partners decide to end the LLP, they file a cancellation document with the Delaware Secretary of State. Canceling LLP status and dissolving the underlying partnership are not the same event. Revoking or canceling the Statement of Qualification strips away limited liability but does not dissolve the general partnership itself. The partnership continues to exist and must be wound down according to the partnership agreement and the DRUPA dissolution provisions.

If LLP status was revoked by the Secretary of State for non-compliance rather than by the partners’ choice, the partnership can apply for reinstatement by correcting the delinquency and paying outstanding fees and penalties. Reinstatement relates back to the date of revocation, but obligations incurred during the gap period may not receive the same protection as those incurred while the LLP was in good standing. That is why the June 1 deadline is the single most important date on a Delaware LLP’s calendar.
