Form an Indiana Limited Partnership — Overview and How We Help

A limited partnership, or LP, is a business built around two kinds of owners. General partners run the operation, make the calls, and shoulder personal responsibility for what the partnership owes. Limited partners put in money, take a share of the profit and loss, and — so long as they stay out of management — risk only the amount they invested. Splitting active control from passive money is the entire reason the form exists.

Indiana governs limited partnerships under Indiana Code Title 23, its version of the Uniform Limited Partnership Act. The statute lays out how an LP comes into being, what a general partner owes the partnership and its limited partners, and how a limited partner can forfeit the liability shield by wandering into control of the business. Because those rules are written into state law, a clear partnership agreement paired with a clean filing record keeps everyone's expectations lined up with what a court would actually enforce.

Where the LP form earns its place

Limited partnerships show up wherever the people with the money are not the people doing the work. Real estate is the classic case: a sponsor who finds and manages the property acts as general partner, and the investors who fund the purchase come in as limited partners who collect distributions. Family businesses use LPs to move economic value down to the next generation while the parents keep control as general partners. Funds, single-project ventures, and closely held operating businesses lean on the same arrangement — a hands-on operator, a set of check-writers, and a bright line between the two.

What an LP is not

An LP is not a limited liability company, and it is not a general partnership. In a general partnership every partner is personally exposed. In an LLC every member can hold liability protection whether they manage or not. The LP sits between them: it requires at least one general partner who accepts full exposure in exchange for control, sitting in front of passive limited partners. If you want everyone protected and everyone free to manage, an LLC is usually the better tool. If you specifically want a passive-investor class standing behind an active operator, the LP was built for exactly that.

The most important thing to grasp about an Indiana LP is the split between the two partner classes, because it decides who is protected and who is not.

General partners

A general partner manages the business and is personally liable for the partnership's debts, contracts, and judgments. If the LP cannot cover an obligation, creditors can reach a general partner's personal assets. Most sponsors soften that exposure by making the general partner a separate entity — often an LLC formed only to serve as the general partner — so no individual carries the liability directly. An Indiana LP has to have at least one general partner at all times; if the last one departs, the partnership generally must admit a replacement or wind down.

Limited partners

A limited partner is an investor. They contribute capital, receive an agreed share of profit, and are liable only up to what they put in. That protection comes with a condition: it holds only while the limited partner stays out of controlling the business. Indiana's statute recognizes a set of activities a limited partner can do without being treated as a general partner — voting on major matters the agreement reserves to them, advising the general partner, guaranteeing a specific debt — but a limited partner who starts running day-to-day operations risks being reclassified and losing the shield. The safe posture is simple: fund the venture, vote on the handful of reserved decisions, and otherwise leave management to the general partner.

Drawing the line cleanly

The partnership agreement is where this boundary gets set in practice. It should spell out exactly what limited partners vote on and what stays with the general partner, so nobody drifts into "control" by accident and undermines the liability structure the LP is supposed to deliver.

An Indiana limited partnership is created by filing a Certificate of Limited Partnership with the Indiana Secretary of State's Business Services Division. Until that certificate is accepted, the LP does not legally exist — an agreement between partners and a shared bank account are not enough on their own.

The Certificate of Limited Partnership

The certificate is a short public filing. It states the partnership's name, the address of its principal office, the name and Indiana street address of its registered agent, and the name and address of each general partner. It does not ask you to reveal the limited partners, their capital contributions, or the internal economics of the deal — those stay in your private partnership agreement, off the public record.

Filing through INBiz

Indiana runs business filings through INBiz, its one-stop online portal for the Secretary of State. You submit the Certificate of Limited Partnership at inbiz.in.gov, and online filings there are fast — often processed within about a business day. Once the certificate is accepted, the LP is on the public record and can operate, sign contracts, and open accounts in its own name. You can confirm a name and later verify your entity's status through the state's business search.

Creating the LP is a one-time event. Keeping it in good standing is a modest but real set of recurring duties, and Indiana's rhythm here surprises owners who assume every state files annually.

The Business Entity Report is biennial

Indiana does not collect an annual report from limited partnerships. Instead it requires a Business Entity Report filed every two years, through INBiz, keyed to the anniversary of your registration. This is the point most owners get wrong: they wait for a yearly notice that never comes, or they file too often. It is an every-other-year obligation, and letting it lapse is what eventually leads to administrative dissolution, so the biennial cadence is worth putting on the calendar the moment you form. The mechanics live on our Indiana LP annual requirements page.

Registered agent upkeep

Your registered agent must stay reachable at an Indiana street address for the life of the LP. If the agent moves, resigns, or becomes unavailable, you file a change with the Secretary of State to keep the record current. An LP with a stale registered agent is technically out of compliance even if its reports are otherwise up to date.

Keep the certificate in step with reality

When general partners change, when the principal office moves, or when the partnership's basic facts shift, the Certificate of Limited Partnership may need to be amended so the public record continues to match what is actually true about the entity.

Every Indiana LP must name a registered agent in its Certificate of Limited Partnership and keep one in place afterward. The registered agent is the fixed point where the state and the courts can always reach your partnership.

What the agent receives

• Service of process — lawsuits, subpoenas, and summonses aimed at the LP
• Official notices from the Secretary of State, including biennial report reminders
• Tax and compliance correspondence routed to the entity

The agent must have a physical street address in Indiana and be available during normal business hours. A post office box does not satisfy the requirement, because the whole point is a real place where legal documents can be hand-delivered.

Your options

You can act as your own registered agent if you have an Indiana street address and are comfortable having it appear in the public record. You can name another trusted person with an Indiana address. Or you can use a commercial registered agent, which keeps a professional address on the public filing instead of your home, and guarantees someone is present to accept documents even when you are traveling or the office is closed.

Mainstay Filing prepares and submits the Certificate of Limited Partnership so you are not left decoding the Indiana Secretary of State's forms and the INBiz portal on your own. You give us the details the state needs — the partnership name, the principal office, the general partner information, and your registered agent choice — and we handle the filing and return your stamped documents once the state processes them.

We also provide registered agent service, so an Indiana business address sits on the public certificate instead of your home, and there is always someone on hand to receive legal papers and state mail for the partnership. After formation, we can track the biennial Business Entity Report cycle and keep your registered agent and public record current as the partnership evolves.

What we don't do

We are a filing service, not a law firm or an accounting practice. We do not draft the economic terms of your partnership agreement, advise on how to divide profit between general and limited partners, or issue tax opinions. Those decisions belong to your attorney and your CPA. What we do is make sure the state-facing paperwork is correct and on time, so you can concentrate on the deal itself.
