The Basics of an Arizona LLP
What is a limited liability partnership?
At its core, an LLP is simply a general partnership that files with the state to bolt on a liability shield. In a plain general partnership, every partner is personally responsible for the firm's debts and for the wrongful acts of the other partners. Registering as an LLP protects each partner from personal liability for the malpractice and misconduct of the other partners and of firm employees. The partnership itself keeps running the way partnerships do — owned and operated by the partners under a partnership agreement.
How is an LLP different from an LLC?
Both give owners a liability shield, but they are different animals. An LLC is a separate legal entity with members; it can have a single owner and is managed by members or designated managers. An LLP is a partnership with two or more partners that has elected LLP status. In Arizona there is even an agency difference: LLCs file with the Corporation Commission, while LLPs register with the Secretary of State. LLPs are especially common among licensed professionals who want partnership-style governance with protection from each other's malpractice.
How is an LLP different from a general partnership?
A general partnership offers no liability shield — the partners are exposed to everything. An LLP is a general partnership that has taken the extra step of registering for the shield. The internal structure can be nearly identical; the difference is the layer of protection that attaches once the state accepts the LLP registration.
Can one person form an LLP?
No. An LLP requires at least two partners, because it is a form of partnership. A solo owner who wants liability protection typically forms an LLC instead.
Registration and the Statutory Agent
Which Arizona agency handles LLPs?
The Arizona Secretary of State, at azsos.gov/business. This is a frequent point of confusion, because LLCs and corporations file with the Arizona Corporation Commission. LLPs are the exception — they go through the Secretary of State. Filing with the wrong agency wastes time and does not accomplish the registration.
What document creates the LLP?
The LLP registration filing — sometimes called a Statement of Qualification — filed with the Secretary of State. It identifies the partnership, states that it elects LLP status, and names the statutory agent and their Arizona address. Once the state accepts it, LLP status takes effect and the shield attaches.
What is a statutory agent?
A statutory agent is Arizona's name for the registered agent. It is the person or company that receives service of process and official state mail on the LLP's behalf. Every Arizona LLP must maintain one with a physical Arizona street address who is available during business hours. You can name a partner, another Arizona resident, or a commercial service.
How long does registration take?
Standard processing at the Secretary of State runs on the order of a couple of weeks. Build that window into any deadline tied to a lease, a loan, or a client engagement, and file early rather than counting on last-minute approval.
Taxes, Compliance, and the Shield
How is an Arizona LLP taxed?
By default as a partnership. The LLP does not pay federal income tax itself; profits and losses pass through to the partners, who report their shares on their personal returns. The partnership files an informational Form 1065 with the IRS and issues a Schedule K-1 to each partner. Arizona has a state income tax, so each partner also reports their share of Arizona-source income on their individual Arizona return.
What ongoing filings does an LLP have?
Arizona LLPs must renew their registration on an annual cycle, with the renewal due in the spring. You also keep a valid statutory agent on file at all times and update the record when key information changes. Separately, the partnership files its federal return each year, and depending on activity you may need Arizona tax accounts and licenses.
What does the liability shield actually protect?
It protects a partner from personal liability for the malpractice, negligence, or misconduct of the other partners and of firm employees. It does not protect a partner from liability for their own wrongful acts, and it does not undo a personal guarantee. If a partner personally signs for a loan or lease, the shield does not release them from that promise.
Do I need a partnership agreement?
Arizona does not require a written partnership agreement, but a multi-partner firm should always have one. Without it, the state's default partnership rules govern profit splits, decisions, and partner exits — and those defaults often do not match what the partners intended.
Practical Questions Firms Ask
Can out-of-state partners own an Arizona LLP?
Yes. Arizona does not impose a residency requirement on the partners of an LLP. The partners can live anywhere. The one Arizona-presence requirement is the statutory agent, who must have a physical Arizona street address — a requirement a commercial service satisfies.
Can an existing general partnership become an LLP?
Yes, and this is a common path. A general partnership that wants to close the personal-liability gap can register as an LLP with the Secretary of State, keeping its existing partnership agreement and tax treatment while adding the shield.
What if my LLP was formed in another state?
If your LLP was formed elsewhere and you want to do business in Arizona, you generally register as a foreign LLP with the Arizona Secretary of State and appoint an Arizona statutory agent. This gives your out-of-state partnership authority to operate here without replacing your home-state registration.
Can Mainstay Filing handle the whole registration?
Yes. We prepare and submit your Arizona LLP registration to the Secretary of State, provide statutory agent service so a partner's home address stays private, and track your annual renewal so the shield does not lapse. We are a filing service, not a law or accounting firm, so we do not draft partnership agreements or give legal or tax advice.
Frequently asked questions
Is an LLP better than an LLC in Arizona?
Neither is universally better — they suit different situations. An LLP fits two or more owners who want partnership-style governance and protection from each other's malpractice, which is why licensed professionals favor it. An LLC works for a single owner or for owners who want a separate entity with member or manager management. Because the tax and liability details depend on your circumstances, it's worth discussing the choice with an attorney or CPA.
Do LLPs pay Arizona state income tax at the entity level?
By default, no. An LLP is a pass-through: profits and losses flow to the partners, who report their shares on their individual Arizona returns. Arizona has a state income tax that applies at the partner level, not to the partnership itself, unless the firm has made an election that changes its tax treatment.
Where do Arizona LLPs register?
With the Arizona Secretary of State at azsos.gov/business — not the Corporation Commission, which handles LLCs and corporations. This split trips up a lot of first-time filers, so confirm you are on the Secretary of State's business filings.
Does an LLP need a statutory agent?
Yes. Every Arizona LLP must maintain a statutory agent with a physical Arizona street address who is available during business hours to receive legal process and state mail. You can name a partner, another Arizona resident, or a commercial statutory agent service.
Can a licensed professional practice be an LLP in Arizona?
Yes, and licensed practices are among the most common LLPs precisely because the shield protects each partner from another partner's malpractice. Professional firms should confirm their licensing board's specific rules on organization and naming before registering, since some boards have additional requirements.
How many partners does an Arizona LLP need?
At least two. An LLP is a form of partnership and cannot exist with a single owner. A solo owner who wants liability protection would form an LLC instead.
