Forming a nonprofit with 501(c)(3) status runs on two tracks: you incorporate as a nonprofit corporation under your state’s law, then apply separately to the IRS for federal tax-exempt recognition. Expect roughly $300 to $900 in government fees across both tracks. The full timeline, from filing articles of incorporation to receiving your IRS determination letter, runs anywhere from a few weeks to over six months depending on which federal application form you file. The sequence matters: mistakes in your incorporation documents can delay or block your federal exemption months later.
Step 1: Incorporate in Your State
Your nonprofit’s legal existence begins at the state level. Pick a name that is distinguishable from every other entity on file with the state, and check the state’s business database before committing. Most states require a corporate designator such as “Inc.,” “Corporation,” or “Incorporated” at the end. Some states let you reserve a name for a short period while you prepare the paperwork.
You also need a registered agent: a person or company with a physical street address in the state of incorporation who agrees to accept legal notices for the organization. A P.O. box will not work. The agent can be a founding board member, an attorney, or a commercial service, and the name and address become part of the public record.
What Your Articles of Incorporation Must Say
The articles are the legal charter that creates your nonprofit. Every state uses its own form, but the substance is remarkably uniform because the IRS effectively dictates what has to be in there. Miss the required language and the IRS will reject your exemption application later.
Your articles need to include:
- A purpose clause limiting the organization’s activities to purposes recognized as tax-exempt under Section 501(c)(3), such as charitable, religious, educational, or scientific purposes.
- A dissolution clause requiring that if the organization shuts down, remaining assets go to another 501(c)(3) or to a government entity for a public purpose, not to any individual.
- Language barring the organization’s earnings from benefiting any private individual, and prohibiting substantial lobbying or political campaign activity.
- Names and addresses of at least one initial director.
- The name and address of the incorporator signing and filing the articles.
The IRS publishes suggested language in Publication 557 that satisfies all of these requirements in a template most state filing offices accept without changes.1Internal Revenue Service. Suggested Language for Corporations and Associations (Per Publication 557) Using that template is the simplest way to avoid a back-and-forth with the IRS months down the road.
File the articles with the state’s business filing office, usually the secretary of state. Most states accept online filings; a few still require paper. Filing fees generally run $30 to $150, though a handful of states charge more. Processing takes a few business days to several weeks, and many states offer expedited review for an additional fee. When the state approves the filing, you receive a certificate of incorporation or an endorsed copy of the articles confirming the entity exists.
Step 2: Get an Employer Identification Number
Before you can open a bank account, hire anyone, or file for federal tax exemption, you need an Employer Identification Number from the IRS. This nine-digit number is the organization’s identity within the federal tax system. You apply using Form SS-4, which asks for the organization’s name, address, entity type, and the name and taxpayer identification number of a responsible party such as a founding director.2Internal Revenue Service. About Form SS-4, Application for Employer Identification Number (EIN)
The fastest route is the IRS online application, which issues the EIN immediately at the end of the session. Fax and mail options exist but take longer.3Internal Revenue Service. Instructions for Form SS-4 (Rev. December 2025) There is no fee.
Step 3: Adopt Bylaws and Hold an Organizational Meeting
With the corporation formed, the board needs internal rules. Bylaws are the operating manual: they are not filed with the state or the IRS, but the IRS will ask about their contents on the exemption application, and they govern how the organization actually runs.
Bylaws typically address board structure (the number of directors, how they are elected, term lengths, and how vacancies are filled — most states require a minimum of three board members), officer titles and responsibilities, meeting and quorum procedures, and the fiscal year the organization will use for tax reporting.
You also need a conflict of interest policy. Form 1023 specifically asks whether you have one, and organizations without a policy invite scrutiny. The policy should require board members to disclose any financial interest in a transaction the organization is considering and to recuse themselves from voting on it. Insiders who receive excessive compensation or other benefits from an exempt organization can face excise taxes under the excess benefit transaction rules of Section 4958 of the Internal Revenue Code.4Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions
Board members owe the organization a duty of care (making informed decisions), a duty of loyalty (putting the organization ahead of personal interests), and a duty of obedience (following the law and staying true to the mission). Directors who ignore these obligations carry personal liability exposure.
The board formally adopts the bylaws and conflict of interest policy at an initial organizational meeting. That meeting also records the first official actions: electing officers, approving the fiscal year, authorizing a bank account, and similar resolutions. Keep the minutes. The IRS may ask for them.
Step 4: Apply to the IRS for 501(c)(3) Recognition
Incorporating as a nonprofit under state law does not make your organization tax-exempt. Federal exemption under Section 501(c)(3) requires a separate application, and the organization is not recognized as exempt until the IRS approves it.5Office of the Law Revision Counsel. 26 USC 508 – Special Rules With Respect to Section 501(c)(3) Organizations Until then, the organization owes federal income tax on any net revenue, and donors cannot deduct their contributions.
Form 1023 or Form 1023-EZ
The IRS offers two paths. The full Form 1023 works for any organization seeking 501(c)(3) status. It requires a detailed narrative describing all past, present, and planned activities, along with financial data — either actual history or three-year projections showing itemized revenues and expenses.6Internal Revenue Service. About Form 1023, Application for Recognition of Exemption Under Section 501(c)(3) of the Internal Revenue Code The IRS uses that information to decide whether the organization qualifies as a public charity or a private foundation. You must also disclose compensation arrangements for officers, directors, and key employees, and explain how those pay rates are set.
The streamlined Form 1023-EZ is available only to smaller organizations that meet every one of these criteria: annual gross receipts have not exceeded $50,000 in any of the past three years, projected gross receipts do not exceed $50,000 in any of the next three years, and total assets do not exceed $250,000.7Internal Revenue Service. Instructions for Form 1023-EZ (Rev. January 2025) Complete the eligibility worksheet in the Form 1023-EZ instructions before filing; a single disqualifying answer means you need the full Form 1023.
The 27-Month Filing Deadline
File your exemption application within 27 months of the end of the month your organization was formed and the IRS will generally recognize your tax-exempt status retroactively to the date of formation. File later and your exemption typically starts only from the date the IRS receives the application.8Internal Revenue Service. Form 1023: Purpose of Questions About Organization Applying More Than 27 Months After Date of Formation Any revenue received during the gap could be subject to federal income tax, and donors who gave during that gap may lose their deductions. For an organization incorporated in March, the deadline falls at the end of June two years later. Put it on the calendar the day you incorporate.
Fees, Filing, and Processing Times
Both forms are submitted only through the Pay.gov electronic portal. You create an account, complete the form online, upload attachments as a single PDF for the full Form 1023, and pay the user fee electronically. The fee is $600 for Form 1023 and $275 for Form 1023-EZ, and it is non-refundable whether or not the application is approved.9Internal Revenue Service. Form 1023 and 1023-EZ: Amount of User Fee
Processing times differ sharply. As of early 2026, the IRS reports that 80% of Form 1023-EZ applications receive a determination within about 22 days. For the full Form 1023, 80% of applications are processed within roughly 191 days, and cases needing further review take longer.10Internal Revenue Service. Where’s My Application for Tax-Exempt Status? During review, an IRS agent may send development letters asking for more information. Responding promptly keeps things moving; slow responses can add months.
Once approved, the IRS issues a determination letter recognizing the organization’s tax-exempt status. Donors, grantmakers, and state agencies will ask to see it as proof of your 501(c)(3) status.11Internal Revenue Service. Exempt Organizations Rulings and Determinations Letters
Step 5: Handle State Tax and Fundraising Registrations
Federal 501(c)(3) recognition does not automatically exempt your organization from state taxes. Most states impose their own income tax, sales tax, or both, and each has its own exemption process. Some states grant automatic exemption once you show your IRS determination letter; others require a separate application to the state revenue department; a few require separate applications for income tax exemption and sales tax exemption. Check with your state’s revenue department shortly after receiving the determination letter.
Roughly 40 states also require nonprofits to register with a state agency, usually the attorney general or secretary of state, before soliciting donations from the public.12Internal Revenue Service. Charitable Solicitation – State Requirements These laws are separate from tax exemption and carry their own forms, fees, and annual renewals. Fees range from nothing to several hundred dollars, sometimes on a sliding scale based on total contributions. Religious organizations, educational institutions, and very small nonprofits are commonly exempt, though the categories vary. If you will fundraise in multiple states, including online fundraising that reaches donors across state lines, you may need to register in each one. Soliciting without registering where required can bring fines and legal action.
Staying Exempt: Annual Filings
Getting 501(c)(3) status is not the last step. Tax-exempt organizations must file an annual information return with the IRS. Which form depends on size: Form 990-N (the e-Postcard) for gross receipts of $50,000 or less, Form 990-EZ for gross receipts under $200,000 and total assets under $500,000, and the full Form 990 for organizations at or above those thresholds. The return is due the 15th day of the fifth month after the end of your fiscal year, which is May 15 for calendar-year organizations. Extensions are available for Forms 990 and 990-EZ but not for the e-Postcard.13Internal Revenue Service. Return Due Dates for Exempt Organizations: Annual Return
The penalty for ignoring this is automatic. An organization that fails to file its required annual return or notice for three consecutive years loses its federal tax-exempt status by operation of law. There is no warning and no grace period. Reinstatement requires filing a new Form 1023 or 1023-EZ and paying the user fee again.14Internal Revenue Service. Automatic Revocation of Exemption for Non-Filing: Frequently Asked Questions Most states also require nonprofit corporations to file an annual or biennial report with the secretary of state, and states that mandate charitable solicitation registration require annual renewals.
