Indiana Limited Partnership FAQ

How do I form a limited partnership in Indiana?

You form an Indiana LP by filing a Certificate of Limited Partnership with the Secretary of State's Business Services Division through the INBiz portal. The certificate names the partnership, its registered agent and Indiana office, and its general partners. Once the state accepts it, the LP legally exists and can operate in its own name. Alongside the filing, you should have a limited partnership agreement in place and obtain an EIN from the IRS.

What is a Certificate of Limited Partnership?

It is the public formation document for an Indiana LP — the LP equivalent of an LLC's articles of organization. It contains the partnership name, the registered agent and registered office, and the general partners. It deliberately does not list the limited partners or the internal economics; those stay private in the partnership agreement. The LP does not exist until this certificate is filed and accepted.

How long does formation take?

Online filings through INBiz are typically fast, often processed within about a business day. The LP becomes active once the certificate is accepted and appears in the state's public records. Even with quick processing, leave a small cushion if you are working toward a hard deadline like a closing.

Do I need to reserve my name first?

No. Name reservation is optional in Indiana. You can file the certificate directly if your name is available. Reserving through INBiz only makes sense when you have chosen a name but are not yet ready to file and want to hold it.

What is the difference between a general partner and a limited partner?

A general partner runs the business and is personally liable for the partnership's debts and obligations. A limited partner supplies capital, shares in profit and loss, and is liable only up to the amount invested — as long as they stay passive. Every Indiana LP needs at least one general partner and at least one limited partner. The two-class split is the whole reason to use an LP instead of another structure.

Can a limited partner lose their liability protection?

Yes, by taking control of the business. Indiana law shields limited partners only while they remain passive investors. Voting on the specific matters the partnership agreement reserves to them, advising the general partner, or guaranteeing a particular debt are generally safe. Directing day-to-day operations is not — a limited partner who does that risks being treated as a general partner and losing the shield.

Can one person be both a general and a limited partner?

A person can hold both roles, but it does not erase general-partner liability. If you are a general partner, you carry the personal exposure that comes with that role regardless of whatever limited-partner interest you also hold. Structuring around this is exactly why many sponsors make the general partner a separate entity, such as an LLC, so no individual bears the exposure directly.

Why do people make the general partner an LLC?

Because the general partner is personally liable and a limited partner is not, sponsors often want to remove the personal exposure entirely. Forming a separate LLC to serve as the general partner means the LLC — not any individual — holds the general-partner liability, while the LLC's own members keep the protection of that structure. It is a common, deliberate layering of the two forms.

How is an Indiana LP taxed?

For federal purposes, a limited partnership is a pass-through entity. It files a partnership return (Form 1065) and issues Schedule K-1s so each partner reports their share of profit or loss on their own return; the LP itself does not pay federal income tax at the entity level. Indiana has its own partnership filing and pass-through treatment. Because tax specifics depend heavily on your situation, confirm your obligations with a CPA.

Does an Indiana LP file an annual report?

No — Indiana uses a biennial Business Entity Report, filed every two years through INBiz, tied to your registration anniversary. This surprises many owners who expect an annual filing. The every-other-year cadence is easy to overlook, and missing it eventually leads to administrative dissolution, so it belongs on the calendar from day one.

What happens if I miss the Business Entity Report?

Indiana provides a window before the entity falls out of good standing, but a persistently unfiled report leads to administrative dissolution — the state ends the LP's active status. A dissolved LP can generally be reinstated by catching up on filings, but that is more expensive and disruptive than filing on time. Keeping the biennial report current is the single easiest way to avoid that whole problem.

Do I need an EIN for my LP?

Yes. Because a limited partnership has more than one owner, the IRS treats it as a partnership and it files its own return under an EIN rather than any partner's Social Security number. You also need the EIN to open a bank account in the partnership's name and to handle payroll or vendor reporting. The IRS issues it at no cost.

Does my Indiana LP need a registered agent?

Yes, at all times. Indiana requires every LP to name a registered agent on its Certificate of Limited Partnership and to maintain one with a physical Indiana street address for the life of the partnership. The agent receives service of process and state notices. The requirement never lapses, and an LP without a valid agent is out of compliance.

Can I be my own registered agent?

A general partner with an Indiana street address who is available during business hours can serve. The trade-offs are that the address becomes public and the person has to be reliably present to accept legal process. Many partnerships use a commercial agent instead to keep a home address private and guarantee availability.

My LP was formed in another state — can it do business in Indiana?

Yes, but it generally has to qualify as a foreign LP first. That means registering with the Indiana Secretary of State through INBiz and appointing an Indiana registered agent, usually supported by a good-standing certificate from the home state. Operating in Indiana without qualifying can block the LP from suing in Indiana courts and expose it to penalties.

Is an LP the same as an LLC?

No. An LLC gives every member liability protection whether they manage or not, and it has no required active owner. An LP requires at least one general partner who accepts full personal liability in exchange for control, standing in front of passive limited partners. Choose an LP when you specifically want a passive-investor class behind an active operator; choose an LLC when you want everyone protected and everyone free to manage.

How is an LP different from a general partnership?

In a general partnership, every partner manages and every partner is personally liable — there is no passive, protected class. An LP adds that protected class: limited partners who invest without exposure beyond their contribution, as long as they stay out of management. The general partnership offers no liability shield to anyone; the LP offers one specifically to the limited partners.

What about an LLP?

A limited liability partnership (LLP) is a different form again, typically used by professional practices, where partners get protection from the malpractice or misconduct of their co-partners. An LP is built around the general/limited split for investment-style ventures. They serve different purposes, and Indiana treats them as distinct entity types with their own filings.

Which is right for my situation?

If you have money coming from investors who want to stay hands-off and an operator who will run everything, the LP fits naturally. If control and protection should be shared equally among the owners, an LLC is usually simpler. Because the choice drives liability and tax outcomes, it is worth a conversation with an attorney or CPA before you commit to the filing.
