To start an NGO in the USA, you form a nonprofit corporation under your state’s laws and then apply to the IRS for federal tax-exempt status, typically under Section 501(c)(3) of the Internal Revenue Code. State incorporation can be done in a few days. The federal exemption usually takes several months, and one deadline in that process (27 months from formation) determines whether your early donors get to deduct their gifts.
Decide What the Organization Will Do and How the IRS Will Classify It
Every 501(c)(3) must be organized and operated exclusively for exempt purposes: charitable, educational, religious, scientific, and literary activities, among others.1Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc Your mission statement has to describe what you will actually do and for whom. “Helping the community” is too vague. “Providing free tutoring in math and reading to students in underserved school districts” gives the IRS something concrete to evaluate.
Before you file anything, sort out whether you want to be a public charity or a private foundation. The IRS puts every 501(c)(3) in one bucket or the other. Most new NGOs want public charity status because it comes with higher donor deduction limits and lighter regulation. To qualify, your organization generally needs to draw more than one-third of its total support from public sources like donations, grants, and program revenue, and no more than one-third from investment income.2Internal Revenue Service. EO Operational Requirements – Requirements for Publicly Supported Charities The IRS measures this on a rolling five-year basis. Fail the test and you default to private foundation status, which brings stricter rules on self-dealing, minimum distributions, and excise taxes.
Recruit a Board
Most states require a nonprofit corporation to have at least three directors. A handful allow as few as one. Directors are legally responsible for keeping the organization on mission, managing its finances, and complying with state and federal law. The IRS will look closely at your board when it reviews your application, so a board stacked with family members or business partners is going to draw conflict-of-interest questions you don’t want.
Draft the Governing Documents
Articles of Incorporation
The articles of incorporation are the public charter that creates the nonprofit. The document typically includes the organization’s name, its registered agent, its purpose, and two clauses the IRS specifically requires: a purpose clause stating the organization is formed exclusively for one or more exempt purposes under Section 501(c)(3), and a dissolution clause providing that if the organization shuts down, its remaining assets go to another 501(c)(3) or to a government body for a public purpose.3Internal Revenue Service. Does the Organizing Document Contain the Dissolution Provision Required Under Section 501(c)(3) Leave either out and the IRS will reject the tax-exemption application.
You also need a registered agent with a physical street address in the state of incorporation to receive legal notices. This can be a board member, an employee, or a commercial service. The corporate name must not conflict with an existing registered entity in the state, and most states require a corporate designator like “Inc.,” “Corp.,” or “Ltd.” Name availability is usually searchable on the Secretary of State’s website.
Bylaws and a Conflict of Interest Policy
Bylaws are the internal rulebook: how directors are elected and removed, meeting frequency, what makes a quorum, how officers are appointed. Bylaws are not filed with the state, but the IRS will want to see them with your exemption application.
You also need a written conflict of interest policy requiring directors and officers to disclose any financial interest that could benefit them personally through the organization’s transactions. The IRS asks specifically whether you have one, and applications without one draw extra scrutiny. The consequences of ignoring conflicts run beyond the application: if an insider receives an excessive benefit from the organization, federal law imposes an excise tax of 25% of the excess benefit on the individual, plus a 10% tax on any manager who knowingly approved the transaction. If the excess benefit is not repaid in the allowed period, the individual faces an additional tax of 200% of the amount involved.4Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions
File With the State and Get an EIN
File the articles of incorporation with the Secretary of State (or equivalent office) in your chosen state. Most states accept online filings and some turn them around the same day. Filing fees vary widely, generally from under $30 to over $200, with most between $25 and $100. Expedited processing is often available for an extra fee.
Once the state approves the filing, your nonprofit legally exists as a corporation. State incorporation alone does not give you federal tax-exempt status, the ability to receive tax-deductible donations, or exemption from state taxes. Those are separate applications.
Next, get an Employer Identification Number from the IRS. This nine-digit tax ID is required for opening a bank account, hiring employees, and filing the exemption application. Most nonprofits apply online through the IRS website and receive the EIN immediately. Form SS-4 also works by fax or mail.5Internal Revenue Service. Obtaining an Employer Identification Number for an Exempt Organization
One timing detail catches founders off guard: do not apply for an EIN until your organization is legally formed with the state. The IRS starts a three-year clock when you receive your EIN, and if you fail to file a required annual return for three consecutive years, your tax-exempt status is automatically revoked, even if you never got around to applying for it.6Internal Revenue Service. Automatic Revocation of Exemption
Apply for 501(c)(3) Status
Form 1023 or Form 1023-EZ
The IRS offers two application paths. The full application is Form 1023. The streamlined version is Form 1023-EZ, and you can use it only if your annual gross receipts have not exceeded $50,000 in any of the past three years, you don’t project exceeding $50,000 in any of the next three, and your total assets are $250,000 or less.7Internal Revenue Service. Do You Have the Required Financial Information Above either threshold, you must file the full Form 1023. Any organization may choose to file Form 1023 regardless of size.8Internal Revenue Service. Instructions for Form 1023-EZ
Both are filed electronically through Pay.gov.9Internal Revenue Service. Applying for Tax Exempt Status The user fee is $600 for Form 1023 and $275 for Form 1023-EZ.10Internal Revenue Service. Form 1023 and 1023-EZ – Amount of User Fee
What Form 1023 Wants From You
Form 1023 requires a detailed narrative for every activity your organization conducts or plans to conduct. For each activity, you explain what it is, who performs it, when and where it happens, how it furthers your exempt purpose, what percentage of your time it takes, and how it’s funded.11Internal Revenue Service. Form 1023 – Detail Required in Narrative Description of Activities You also provide three years of financial data, actual or projected, including anticipated revenue from donations, grants, and program services. Board compensation and personal relationships among board members must be disclosed.
Both forms also ask you to select an NTEE (National Taxonomy of Exempt Entities) code categorizing your primary activity. It follows the organization through IRS records, so pick the right one.
The 27-Month Deadline
File within 27 months of the end of the month your organization was legally formed, and the IRS will recognize your tax-exempt status retroactively to the date of formation. Miss that window and your exemption only kicks in from the date the IRS receives your application, meaning donations received in the gap may not qualify as tax-deductible for donors.12Internal Revenue Service. Purpose of Questions About Organization Applying More Than 27 Months After Date of Formation This is one of the most commonly missed deadlines in nonprofit formation.
Processing Times
As of early 2026, the IRS issues 80% of Form 1023-EZ determinations within 22 days. The full Form 1023 takes much longer: 80% of determinations are issued within roughly 191 days, about six and a half months. Applications flagged for additional review can run longer.13Internal Revenue Service. Where’s My Application for Tax-Exempt Status The IRS receives over 115,000 exemption applications a year, and delays are common. When approved, you receive a determination letter. Grantmakers and major donors will ask to see it.
Know the Limits on Lobbying and Political Activity
Federal tax law splits political engagement into two categories for 501(c)(3) organizations, and confusing them is one of the fastest ways to lose your exemption.
Lobbying, meaning efforts to influence legislation, is allowed but cannot be a “substantial part” of your activities.1Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc The IRS has never precisely defined “substantial.” Public charities can elect under Section 501(h) to switch to a concrete expenditure test that sets dollar limits based on total exempt-purpose expenditures. For organizations spending $500,000 or less on exempt purposes, the lobbying limit is 20% of that amount. Grassroots lobbying (encouraging the general public to contact legislators) is capped at one-quarter of the overall lobbying limit.
Political campaign activity is different: it is absolutely prohibited. A 501(c)(3) cannot support or oppose any candidate for public office, directly or indirectly. That includes endorsements, financial contributions, letting candidates use organizational resources, and communications that show bias for or against a candidate. Nonpartisan voter education, registration drives, and candidate forums open to all candidates are generally permitted. Violating the campaign prohibition can trigger excise taxes on both the organization and its managers in addition to costing you the exemption.
Handle State Tax Exemption and Charitable Solicitation Registration
Federal 501(c)(3) recognition does not automatically exempt you from state-level taxes. Most states offer nonprofit exemptions from state income tax, sales tax, and sometimes property tax, but each requires a separate application to the relevant state agency. Some states grant the exemption based on your IRS determination letter alone; others have their own forms and criteria. Until you complete the state process, your organization may owe state taxes even though it’s federally exempt.
Before soliciting donations from the public, check whether your state requires you to register as a charitable solicitor. Most states have such laws, and some require periodic financial reports afterward.14Internal Revenue Service. Charitable Solicitation – State Requirements Initial registration fees are modest in most states, typically from nothing to around $50, though some charge more based on revenue.
Online fundraising complicates the picture. An organization soliciting through a website or email may trigger registration requirements in every state where donors are located, not just its home state. Enforcement varies by state, but failing to register before soliciting can bring fines and regulator problems that are painful for a new organization to untangle.
Stay Compliant After the Determination Letter
Annual IRS Filings
Tax-exempt status comes with a permanent filing obligation. Which form you file depends on size:15Internal Revenue Service. Form 990 Series – Which Forms Do Exempt Organizations File
- Form 990-N (e-Postcard) for organizations with gross receipts of $50,000 or less. A brief electronic notice with basic identifying information.
- Form 990-EZ for organizations with gross receipts under $200,000 and total assets under $500,000.
- Form 990 for organizations with gross receipts of $200,000 or more, or total assets of $500,000 or more.
Miss this filing for three consecutive years and your tax-exempt status is automatically revoked, effective on the third missed return’s due date. Reinstatement requires a new application and a new user fee, with no guarantee of retroactive reinstatement.6Internal Revenue Service. Automatic Revocation of Exemption This is the single most common compliance failure among small nonprofits, often because founders don’t realize that even organizations with zero revenue have to file something.
Federal law also requires exempt organizations to make their exemption application and annual Form 990 returns available for public inspection on request.16Internal Revenue Service. Exempt Organization Public Disclosure and Availability Requirements
State Annual Reports
Most states require nonprofit corporations to file a periodic report (annual or biennial) with the Secretary of State to keep their corporate standing. Fees and deadlines vary. Failing to file can result in administrative dissolution of the corporation, a separate and more immediate problem than losing tax-exempt status because it means the organization no longer legally exists.
Payroll Taxes If You Hire
If your NGO hires employees, it must withhold and pay federal income taxes and generally Social Security and Medicare taxes on wages, like any other employer. The 501(c)(3) designation does not exempt you from payroll tax obligations. Organizations recognized under Section 501(c)(3) are exempt from the Federal Unemployment Tax Act (FUTA), so you do not pay federal unemployment tax on employee wages.17Internal Revenue Service. Section 501(c)(3) Organizations – FUTA Exemption State unemployment rules vary, and some states let nonprofits reimburse the state for actual unemployment claims rather than pay a tax rate. Worker classification is a common early problem: treating employees as independent contractors to sidestep payroll taxes can produce back taxes, penalties, and interest, because the IRS looks at whether the organization controls how, when, and where the work is done, not just what the contract says.
