Indiana LLP Frequently Asked Questions

What is a limited liability partnership?

A limited liability partnership is a general partnership that has registered with the state to give its partners a liability shield. In an ordinary general partnership, every partner is personally liable for the debts of the business and for the wrongful acts of the other partners. Once the partnership registers as an LLP, a partner is generally protected from the partnership's obligations and from another partner's negligence or misconduct. The registration is the one legal step that separates an LLP from a plain general partnership.

How is an LLP different from an LLC?

They are separate entity types. An LLC is owned by members and created by filing Articles of Organization; it can be a single-owner entity. An LLP begins as a general partnership — which by definition requires two or more people — and becomes an LLP by filing a Statement of Qualification. The LLP is run directly by its partners under a partnership agreement, while an LLC can be member-managed or manager-managed. Both provide a liability shield and both are pass-through entities for taxes, but they arise under different parts of the law and use different terminology.

Who typically forms an LLP in Indiana?

LLPs are the default choice for licensed professional groups — law firms, accounting practices, medical and dental groups, architecture and engineering firms, and financial advisory partnerships. The draw is that each partner is protected from a colleague's malpractice while the group keeps the flexible, partner-run structure of a partnership. Non-professional businesses can also register as LLPs in Indiana, but the professional context is where the form is most common.

Can a single person form an LLP?

No. A partnership by definition requires at least two partners, so a solo operator cannot form an LLP. A single owner who wants a liability shield would typically form a single-member LLC instead. If you have one or more co-owners and want partner-level liability protection, the LLP is the natural fit.

What agency handles LLP registration in Indiana?

The Indiana Secretary of State's Business Services Division, through the INBiz online portal at inbiz.in.gov. INBiz is Indiana's one-stop platform for business filings, and nearly all LLP registrations, changes, and reports run through it.

What do I file to register an LLP?

You file a Statement of Qualification — the registration as a limited liability partnership — through INBiz. It captures the partnership's name, principal office address, and registered agent, and confirms that the partnership is registering for LLP status. It does not require you to disclose partners' ownership percentages or internal financial arrangements.

How long does registration take?

INBiz online filings typically process in about one business day and often the same day. Paper filings by mail take several business days. Once processed, the LLP appears in Indiana's public business search and your confirmation documents are available.

Do I have to live in Indiana to register an LLP there?

No. Indiana does not impose a residency requirement on partners. The only in-state requirement is the registered agent, who must have a physical Indiana street address and be available during business hours. A commercial registered agent service satisfies that without any partner living in the state.

Does my LLP need a registered agent?

Yes, at all times. Every Indiana LLP must maintain a registered agent with a physical Indiana street address who is available during business hours to receive service of process and state notices. You can be your own agent, name a trusted person, or use a commercial service.

How often does an Indiana LLP file a report?

Every two years. Indiana uses a biennial Business Entity Report rather than an annual one, filed through INBiz. This is one of the most common points of confusion for people used to annual reports elsewhere. Because it comes only every other year, it is easy to forget — set a reminder or use a service that tracks it, because a prolonged lapse leads to administrative dissolution.

What happens if I miss the biennial report?

Indiana provides a grace period after the due date before a late fee applies, but continued failure to file eventually results in the LLP being administratively dissolved. A dissolved LLP loses good standing and its name protection. Reinstatement is possible but requires curing the missed reports and paying the associated fees, which is more expensive and disruptive than simply filing on time.

Do I need to keep my registered agent current?

Yes. If your agent moves, resigns, or you switch agents, update the record through INBiz promptly. A stale agent address puts the LLP out of compliance and risks legal process being delivered to an address no one monitors.

Does Indiana require a partnership agreement?

No — you do not file a partnership agreement with the state, and it never becomes public. But every LLP should have a written one. It governs profit splits, voting, admitting and removing partners, and dissolution. Without it, Indiana's statutory defaults fill the gaps, and those defaults often do not match what the partners intended.

How is an Indiana LLP taxed?

As a partnership. The LLP does not pay income tax at the entity level; profits and losses pass through to the partners, who report their share on their personal returns via a Schedule K-1 from the partnership's federal Form 1065. Indiana requires a partnership information return, and partners account for Indiana-source income on their individual returns. There is no double taxation as with a C-corporation. Confirm the specifics with a CPA.

What are the naming rules for an Indiana LLP?

The name must include an LLP designator such as "Limited Liability Partnership," "LLP," or "L.L.P.," must be distinguishable from other names on record with the Secretary of State, and cannot falsely imply a government affiliation. Certain restricted words (relating to banking, trust, or insurance) may require regulatory approval. Check availability in the Indiana business search before filing.

Do I need an EIN for my LLP?

Yes. Because a partnership files its own federal return (Form 1065) and issues K-1s to partners, an LLP needs an Employer Identification Number from the IRS. The EIN is free and issued immediately when you apply online at IRS.gov. Banks also require it to open a business account in the partnership's name.

How do I dissolve an Indiana LLP?

When the partners decide to close the business, you wind up the partnership's affairs — settling debts, distributing remaining assets, and resolving obligations — and file the appropriate dissolution or withdrawal document with the Secretary of State through INBiz. Formally dissolving is cleaner than letting the LLP lapse, because it ends the biennial report and agent obligations and stops liabilities from accruing against an entity you are no longer running.

What does Mainstay Filing do for an Indiana LLP?

Mainstay Filing prepares and submits your Statement of Qualification through INBiz, so you do not have to interpret the portal or guess at what the registration needs. You provide the partnership name, address, and registered agent choice; we file it and return the confirmed documents. We also include registered agent service and track the biennial Business Entity Report so the deadline does not slip.

What does Mainstay Filing not do?

We are a filing service, not a law firm or accounting firm. We do not draft the economic terms of your partnership agreement, advise on how partners should split profits or equity, or provide tax or legal opinions. For those decisions — particularly for a professional practice — you want a business attorney and a CPA. Our role is the state-facing paperwork, done correctly and on time.

Can you help if my LLP was formed in another state?

Yes. If your partnership is registered elsewhere and you are doing business in Indiana, we can handle the foreign qualification — the application for authority to transact business — and serve as your Indiana registered agent, which is a mandatory part of qualifying here. See the foreign registration page for the details of that process.
