The Real Cost of Forming and Running an Arizona LLP

The core cost of starting an Arizona LLP is the registration filed with the Arizona Secretary of State. This is the fee that converts your general partnership into a limited liability partnership and gives each partner the liability shield. The exact current amount is shown in the receipt card on this page, which pulls live figures from our data so what you see is what you are charged — no markup buried in the total.

What the registration fee covers

The state registration fee covers acceptance of your LLP filing and the creation of your public record. It is a one-time charge at formation. It does not cover the EIN (which is free from the IRS), a partnership agreement, or any professional licenses your firm may need — those are separate categories covered below.

What it does not include

Arizona's registration fee is separate from the annual renewal you will pay every year to keep the LLP in good standing. It is also separate from statutory agent service if you use a commercial provider. Thinking of formation as a single number is where budgets go wrong; the first-year cost is really the registration plus whatever recurring items you choose.

An LLP is not a one-and-done expense. To keep the shield reliable and the firm in good standing, you carry recurring costs every year. Missing them can cost far more than paying them.

Annual renewal

Arizona LLPs must renew their registration with the Secretary of State each year, with the renewal due in the spring. The renewal fee is a recurring state charge, and the receipt card reflects the current amount. Missing the renewal jeopardizes your good standing — and a lapse in good standing undermines the very shield you registered to obtain. This is the single most important recurring cost to calendar.

Statutory agent service

If you hire a commercial statutory agent service on its own rather than naming a partner, that is an annual cost. What you get for it is a private Arizona address that keeps a partner's home off the public record and guaranteed availability to receive legal documents during business hours. Firms whose partners travel or work from home almost always find this worth it — and firms that register through Mainstay never pay it as its own bill, because the agent is included in the flat yearly service price.

Taxes

The LLP itself does not pay federal income tax, but the partners pay tax on their shares of the firm's income, and the partnership files a federal informational return each year. Preparing Form 1065 and the partners' K-1s usually means an accountant's fee, which is a real annual cost even though it is not paid to the state.

Beyond the state fees, several costs show up either once at formation or in specific situations. Budgeting for them up front avoids mid-launch surprises.

EIN

A federal Employer Identification Number is required for an LLP, and it is free directly from the IRS. Some services charge to obtain one on your behalf as a convenience, but the number itself carries no federal fee.

Partnership agreement

Arizona does not require a written partnership agreement, but a multi-partner firm should have one, and having an attorney draft or review it is a sensible one-time cost. It is cheaper than litigating a partner dispute later without a written framework in place.

Foreign qualification

If your LLP was formed in another state and you register to do business in Arizona, that foreign qualification carries its own state fee, plus the cost of obtaining a good-standing certificate from your home state. This applies only to out-of-state partnerships.

Name reservation and amendments

If you reserve a name before registering, or later amend your registration when key details change, those filings carry their own state fees. They are situational — many firms never pay them — but they exist.

Because LLPs are so common among licensed professionals, a professional practice should budget for costs a general business would not face.

Licensing

Law firms, accounting practices, medical and dental groups, architecture and engineering firms, and similar practices carry professional licensing fees at both the individual and, sometimes, the firm level. These renew on their own schedules and are entirely separate from the LLP registration. Confirm your board's requirements early, because some boards impose firm-level registration fees on top of individual licenses.

Insurance

Many professional partnerships carry malpractice or professional liability insurance. While the LLP shield protects a partner from another partner's misconduct, it does not eliminate the firm's exposure or a partner's responsibility for their own work — so insurance remains a meaningful, recurring cost that firms should plan for alongside the state fees.

Arizona transaction privilege tax and local licenses

Depending on the nature of the practice and where it operates, the firm may need an Arizona transaction privilege tax license and city-level business licenses. These carry their own fees and renewal cycles. None of them are covered by the LLP registration, so treat them as separate line items when you build your budget.

Putting it together

A realistic first-year budget for an Arizona LLP is the state registration fee, plus statutory agent coverage — its own charge with a stand-alone provider, though folded into the single yearly price when Mainstay registers you — plus accountant and legal costs for the partnership agreement and tax setup, plus any professional licensing and insurance. In following years, the recurring core is the state's annual renewal fee, agent coverage on the same basis, tax preparation, and license and insurance renewals. The receipt card on this page keeps the state figures accurate and current.
