How to start a nonprofit in Indiana

Short answer: To start a nonprofit in Indiana, you incorporate by filing Articles of Incorporation (Form 4162) with the Indiana Secretary of State through the INBiz portal (about $31 online as of 2026), get a free EIN from the IRS, adopt bylaws, and seat a board of at least three directors. Then comes the part people miss: a nonprofit is not automatically tax-exempt, so you file IRS Form 1023 (or 1023-EZ) to become a 501(c)(3). On the Indiana side, the good news is there is no separate state charitable-solicitation registration for charities that raise money with their own staff and volunteers. To shop tax-free, you register with the Indiana Department of Revenue using Form NP-20A through INTIME, then issue Form NP-1 exemption certificates to vendors, and you file a short Form NP-20R report every five years to stay registered. Indiana does exempt purchases made to carry on the nonprofit’s exempt purpose, which makes it a lighter state to operate in than many.

The federal core — EIN, bylaws, board, and the 501(c)(3) application — is the same in every state. For the full national walkthrough, read how to start a nonprofit; this page focuses on the Indiana layer stacked on top of it, where the state-specific forms, fees, and agencies actually live.

The formation steps that are the same anywhere

Forming a nonprofit in Indiana follows the standard checklist, and most of it is federal rather than state-specific:

1. Incorporate as a nonprofit corporation (the Indiana-specific part — covered in detail below).
2. Get an EIN — a free federal tax ID from the IRS, applied for directly at irs.gov. Never pay a third party for one; the EIN is always free.
3. Adopt bylaws — the organization’s internal rulebook for decisions, leadership, and money. Start from a proven document rather than a blank page; see nonprofit bylaws for what to include.
4. Seat a board of directors who govern the organization, set policy, and hold it accountable.
5. Apply for 501(c)(3) with Form 1023 — this is the step that turns a nonprofit corporation into a tax-exempt charity. Unlike a church, an ordinary nonprofit is not automatically exempt; you must file IRS Form 1023 (or the streamlined Form 1023-EZ if you qualify) and receive a determination letter (IRS, applying for 501(c)(3) status). The full path is in how to start a 501(c)(3).
6. Open a bank account in the nonprofit’s legal name using the EIN and formation documents.
7. Set up the books on fund accounting from day one, before the first grant or donation arrives.

Each of these is walked step by step in the national formation guide linked above. The rest of this page is the Indiana layer on top.

Incorporating a nonprofit in Indiana

Indiana creates the nonprofit as a legal entity when you file Articles of Incorporation (Form 4162) for a domestic nonprofit corporation with the Indiana Secretary of State. Filing runs through the state’s INBiz portal, and the fee is $31 online as of 2026 (a $30 base fee plus a $1 card-processing charge), or $50 if you mail a paper form; confirm the current amount with the Indiana Secretary of State, since fees change. Online filings are typically processed within a day, while mailed forms take about a week.

Form 4162 asks for the nonprofit’s name, its registered agent and registered office in Indiana, and its statement of purpose. Two clauses matter to the IRS, and you should make sure both appear in your Articles rather than leaving them out:

• A 501(c)(3) purpose clause stating the organization is formed exclusively for charitable, religious, educational, or other exempt purposes.
• A dissolution clause stating that if the nonprofit closes, its assets pass to another 501(c)(3) organization, not to any individual.

Getting that language right at formation saves an amendment later. The full breakdown of what these documents need is in articles of incorporation. On board size, Indiana sets a clear floor: a nonprofit corporation must have at least three directors under Indiana Code 23-17-12-3, and the number can be increased or decreased in the bylaws but never below three. That three-director minimum lines up with what the IRS wants to see anyway, since it treats a one- or two-person board as a governance red flag on the 1023.

Charitable registration in Indiana

Here is where Indiana is genuinely easier than most states. Many states make a charity register with a state agency before it can solicit donations — California and Florida among them. Indiana does not. A charity that raises money using its own staff and volunteers is not required to register or report its fundraising campaigns to the state, which removes a whole annual filing that nonprofits in other states have to carry (Indiana Attorney General, charitable fundraising).

The exception is narrow and worth knowing. If you hire a professional solicitor — an outside firm paid to raise money on your behalf — that firm must register with the Attorney General’s Consumer Protection Division and disclose the share of contributions the charity will actually receive. The registration burden sits on the paid fundraiser, not on your nonprofit. So as long as your appeals go out under your own name through your own people, you skip the state charity-registration step entirely. A handful of Indiana counties and cities ask in-person solicitors to register locally, so check the rules where you actually fundraise, but there is no statewide charity registration to file.

Claiming the Indiana sales tax exemption

A federal 501(c)(3) determination letter exempts your nonprofit from federal income tax, but it does not make your purchases tax-free in Indiana. That sales tax exemption is a separate registration with the Indiana Department of Revenue (DOR), and the process was rebuilt in 2022 and 2023, so older guides describe it wrong.

The first step is Form NP-20A, the Nonprofit Application for Sales Tax Exemption, filed electronically through the DOR’s INTIME portal at intime.dor.in.gov. Once the DOR accepts the application, the organization is registered as exempt and can begin buying tax-free for its exempt activities (Indiana DOR, nonprofit tax forms). Indiana does exempt purchases the nonprofit makes to carry on its exempt purpose — the equipment, supplies, and goods used for the mission — which is a real advantage over states that tax nonprofit purchases the same as a business. Items bought for private member benefit, like food or lodging at a members’ event, stay taxable.

The certificate part changed, and this is the piece people get wrong: as of January 1, 2023, registered nonprofits issue Form NP-1, the Nonprofit Sales Tax Exemption Certificate, to vendors — not the old Form ST-105. Form NP-1 is generated inside INTIME for each specific vendor, combines proof of exemption with the certificate itself, and expires after five years. A vendor that asks for your “exemption certificate” should receive an NP-1 generated for them, not a generic ST-105.

Staying registered takes one more recurring filing, and it is light. The old annual NP-20 report is gone; in its place is Form NP-20R, the Nonprofit Organization’s Report, filed through INTIME every five years by May 15 to keep the exemption active. Five-year cadence rather than annual is part of what makes Indiana a low-overhead state to run a nonprofit in — but mark the date, because letting NP-20R lapse can cost you the registration.

Setting up the books once the nonprofit exists in Indiana

Once the entity is formed and the exemption is registered, the work shifts from one-time paperwork to the monthly routine — and that routine is where nonprofits either hold together or quietly fall apart. A nonprofit holds money in trust for the people and purposes it serves, much of it restricted by donors or grant terms, so it tracks money by fund rather than as a single bottom line. Set the books on fund accounting before the first grant lands, keep the giving records donors need, and document that the board reviews the finances; the discipline is covered in nonprofit accounting. The Indiana angle to keep on your calendar is the NP-20R — that five-year report to the DOR is what keeps your sales tax exemption alive, and it is easy to forget precisely because it comes around so rarely.

FAQ

How much does it cost to start a nonprofit in Indiana? The required state cost is low. Filing Articles of Incorporation (Form 4162) through INBiz costs about $31 online as of 2026, or $50 by paper — and that is essentially the whole state bill, because Indiana charges nonprofits no fee to register for the sales tax exemption (Form NP-20A) and has no state charity-registration fee for charities using their own staff. The bigger line item is federal: the IRS charges a $275 user fee for Form 1023-EZ or $600 for the full Form 1023, which is what actually makes you a 501(c)(3). Realistically, a small Indiana nonprofit can be stood up properly for the IRS fee plus about $31 in state filing, once you include the federal exemption application.

Does Indiana require nonprofits to register for charitable solicitation? No, in the common case. A charity that solicits using its own employees and volunteers is not required to register or report its fundraising to the state (Indiana Attorney General, charitable fundraising). The one exception is hiring an outside professional solicitor, which triggers a registration requirement on that firm with the Attorney General’s Consumer Protection Division. This is one of the ways Indiana is lighter than states like California, where charities themselves must register before they fundraise.

How does an Indiana nonprofit buy things tax-free? First register with the Indiana Department of Revenue by filing Form NP-20A through the INTIME portal. After the DOR accepts it, generate a Form NP-1 certificate in INTIME for each vendor you buy from and give that vendor the NP-1 — it replaced the old Form ST-105 for nonprofits on January 1, 2023. The exemption covers purchases used to carry on your exempt purpose, and you keep it current by filing Form NP-20R every five years by May 15.

How long does it take to start a nonprofit in Indiana? The Indiana incorporation itself is quick — INBiz often processes online Articles within a day, and the sales tax registration through INTIME is fast once the entity exists. The slow part is federal: the IRS can take anywhere from about a month (Form 1023-EZ) to many months (full Form 1023) to issue the 501(c)(3) determination letter. Plan for the state entity to exist within days but the full tax-exempt status to take several months end to end.
