How to start a nonprofit in South Dakota

Short answer: To start a nonprofit in South Dakota, you incorporate by filing Articles of Incorporation (Domestic Nonprofit) with the South Dakota Secretary of State ($30 online, $50 by paper 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). South Dakota makes the state layer unusually light — it does not require a general charitable-solicitation registration, and it has no state corporate income tax. The honest catch is sales tax: South Dakota does not give ordinary charities a blanket exemption, so most nonprofits pay the state’s 4.2% sales tax on what they buy.

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 South Dakota 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 South Dakota follows the standard checklist, and most of it is federal rather than state-specific:

1. Incorporate as a nonprofit corporation (the South Dakota-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 South Dakota layer on top.

Incorporating a nonprofit in South Dakota

South Dakota creates the nonprofit as a legal entity when you file Articles of Incorporation (Domestic Nonprofit) with the South Dakota Secretary of State. The filing fee is $30 filed online and $50 on paper as of 2026; confirm the current amount with the South Dakota Secretary of State, since fees change. The state pushes filers toward its online portal, where the form and payment run together.

The Articles ask for the nonprofit’s name, its registered agent and registered office in South Dakota, and its statement of purpose. The Secretary of State’s own guidance flags that organizations seeking IRS 501(c)(3) status should keep two clauses in the document rather than stripping 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, South Dakota’s Nonprofit Corporation Act sets a real floor: a nonprofit’s board must have at least three directors under SDCL 47-23-14. Confirm the current statute, but plan on recruiting three mostly-unrelated directors, which is also what the IRS wants to see on the 1023.

One ongoing obligation the state requires of every nonprofit: an annual report to the Secretary of State, due by the first day of your incorporation anniversary month, carrying a $10 fee as of 2026. The annual report keeps your officers, registered agent, and address current on the public record; let it lapse and the state can administratively dissolve the corporation.

Charitable registration in South Dakota

Here is where South Dakota saves you a step that costs nonprofits in most other states money and paperwork every year: the state does not require a general charitable-solicitation registration. A South Dakota nonprofit can legally ask the public for donations without filing a charity-registration form with any state agency. The state’s own consumer-protection guidance puts it plainly — South Dakota does not have licensing or registration requirements for nonprofit or charitable organizations (South Dakota Consumer Protection, charities).

South Dakota’s stance makes it one of a small handful of no-registration states, and it removes both the initial registration fee and the annual renewal that nonprofits elsewhere have to track. Two caveats keep this honest, though. First, if your organization hires a paid solicitor to run a telephone fundraising campaign on its behalf, that solicitor must register and post a bond with the Attorney General’s Division of Consumer Protection — the obligation falls on the paid fundraiser, not on your charity, but it is worth knowing before you sign a contract. Second, the no-registration rule is a South Dakota rule; the moment you solicit donors in other states, their registration laws can apply, so a nonprofit fundraising nationally still has to look at where its donors live.

South Dakota sales tax and your nonprofit

Now the honest answer most state guides skip: South Dakota does not give nonprofits a blanket sales tax exemption. The state runs a broad sales and use tax — the state rate is 4.2% as of 2026, before any municipal add-on — and that tax treats a typical charity the same as a for-profit business (South Dakota Department of Revenue, sales and use tax). Holding a federal 501(c)(3) letter does not, by itself, get you out of South Dakota sales tax.

The exemptions that do exist are narrow and specific. South Dakota grants sales-tax-exempt status to a defined list: government agencies, public schools and universities, nonprofit hospitals, certain religious and private schools, and relief agencies — 501(c)(3) organizations that devote their resources exclusively to relief of the poor, distressed, or underprivileged and have a physical presence in the state (South Dakota Department of Revenue, exempt entities). Relief agencies and qualifying schools must apply to the Department of Revenue for approval and renew periodically; the exemption is not automatic and not handed to every charity. So an ordinary South Dakota nonprofit — an arts group, a youth program, an animal rescue — generally pays sales tax on the equipment, supplies, and goods it buys. Budget as if your purchases are taxable, then check with the Department of Revenue whether your specific mission fits one of the narrow exempt categories before you rely on it.

The bright side balances the ledger: South Dakota has no state corporate income tax at all (South Dakota Department of Revenue, business taxes). So while your nonprofit will not escape sales tax the way it might in another state, it also never files a state corporate income tax return or claims a state income-tax exemption, because there is no such tax to be exempt from.

Setting up the books once the nonprofit exists in South Dakota

Once the entity is formed and the 501(c)(3) application is filed, 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 South Dakota item to keep on your calendar is the annual report to the Secretary of State each anniversary month — it is a small fee and a quick filing, but missing it can put the corporation into delinquent status and eventually trigger administrative dissolution.

FAQ

How much does it cost to start a nonprofit in South Dakota? The required state cost is low. Filing Articles of Incorporation costs $30 online ($50 by paper) as of 2026, and there is no charitable-registration fee because South Dakota does not require that registration — so the state paperwork is roughly $30 plus your time. 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 South Dakota nonprofit can be stood up properly for a few hundred dollars once you include the federal exemption application.

Does South Dakota require a nonprofit to register before fundraising? No. South Dakota does not have a general charitable-solicitation registration requirement, so a nonprofit can solicit donations from South Dakota residents without filing a charity-registration form with the state (South Dakota Consumer Protection, charities). The exceptions are narrow: a paid solicitor running a phone campaign for you must register and bond with the Attorney General, and soliciting donors in other states can trigger those states’ own registration laws.

Is a South Dakota nonprofit exempt from sales tax? Usually not. South Dakota grants sales-tax exemption only to specific categories — government, public schools, nonprofit hospitals, certain religious and private schools, and qualifying relief agencies that serve the poor or distressed and apply to the Department of Revenue. An ordinary 501(c)(3) charity generally pays the state’s 4.2% sales tax on its purchases. Check the Department of Revenue’s exempt-entities guidance to see whether your mission fits one of the narrow exempt categories.

How many directors does a South Dakota nonprofit need? South Dakota’s Nonprofit Corporation Act requires a board of at least three directors under SDCL 47-23-14. That floor lines up with what the IRS wants to see anyway: a board of three or more mostly-unrelated directors signals real governance and smooths the Form 1023 review. So recruit at least three people willing to serve before you apply for tax-exempt status.
