A private school applies for federal tax-exempt status by filing IRS Form 1023, or the shorter Form 1023-EZ if it qualifies by size, at a user fee of $600 or $275. Public schools generally skip this step because they are already treated as government instrumentalities. To avoid sales tax on purchases, most schools also need a separate exemption certificate from their state’s department of revenue, which is a distinct application from anything filed with the IRS. The right tax exempt form for a school depends on whether it is public or private, how large it is, and which state it operates in.
Public Schools and Private Schools File Differently
Public schools operated by a state, county, or municipality are treated as government instrumentalities for federal tax purposes. They do not file Form 1023 and do not need an IRS determination letter; their exempt status flows from being part of government. If you work at a public school, the form that matters to you is the state sales tax exemption certificate, not anything at the federal level.
Private schools, charter schools, and religious schools organized as nonprofits take a different path. They must apply for recognition under Internal Revenue Code Section 501(c)(3). The IRS will not assume exempt status just because the school serves an educational purpose. Until the determination letter arrives, the school is technically a taxable entity.
Form 1023 or Form 1023-EZ
Form 1023 is the standard application. It asks for a detailed narrative of the school’s daily activities, curriculum, grading approach, enrollment policies, and a breakdown of revenue sources and expenses. The financial section covers the past three years, or projected figures for newer schools. The user fee is $600 and is non-refundable regardless of the outcome.1Internal Revenue Service. Form 1023 and 1023-EZ: Amount of User Fee
Smaller schools may use the streamlined Form 1023-EZ if their annual gross receipts have not exceeded $50,000 in any of the past three years, are not projected to exceed that amount in the next three years, and total assets do not exceed $250,000.2Internal Revenue Service. About Form 1023, Application for Recognition of Exemption Under Section 501(c)(3) of the Internal Revenue Code The 1023-EZ costs $275. Schools that don’t meet both thresholds must use the full Form 1023.
Both forms are filed electronically through Pay.gov. There is no paper option. The IRS processes about 80 percent of Form 1023-EZ applications within roughly three weeks; the full Form 1023 takes considerably longer, with 80 percent of determinations issued within about 191 days.3Internal Revenue Service.

The 27-Month Window
File within 27 months of the end of the month the school was formed and the IRS can recognize exemption retroactively to the date of formation.4Internal Revenue Service. Form 1023: Purpose of Questions About Organization Applying More Than 27 Months After Date of Formation Miss that window and the exemption generally starts only from the date the IRS receives the application. For a school that took in donations or ran tuition-free programs during its early months, losing retroactive coverage can create unexpected tax liability.
What to Have in Place Before Filing
The school needs an Employer Identification Number, which the IRS uses to identify the organization. Every tax-exempt entity needs one, even before hiring any employees.5Internal Revenue Service. Employer Identification Number
The organizing documents, usually articles of incorporation or a trust instrument, must include two specific provisions: a purpose clause limiting activities to educational and charitable functions, and a dissolution clause directing assets to another exempt organization or a government entity if the school ever shuts down.6Internal Revenue Service. Does the Organizing Document Contain the Dissolution Provision Required Under Section 501(c)(3) The IRS will not process an application without both clauses.
The organization cannot participate in political campaigns or devote a substantial part of its activities to lobbying.7Internal Revenue Service. Exemption Requirements – 501(c)(3) Organizations Endorsing candidates or spending heavily on legislative advocacy can disqualify the application.
Nondiscrimination Rules for Private Schools
Private schools face requirements that other 501(c)(3) organizations don’t. Under Revenue Procedure 75-50, every private school seeking or holding tax-exempt status must adopt and publicize a racially nondiscriminatory admissions policy. The school must admit students of any race, color, national origin, and ethnic origin to all programs and activities, and cannot discriminate in admissions, financial aid, or athletics.8Internal Revenue Service. Instructions for Form 1023
The policy must be publicized: publishing a notice in a newspaper of general circulation, broadcasting it over media, or displaying it prominently on the school’s primary website. The website option is the most common today. The statement must follow the format set by the IRS, naming the school and affirming nondiscrimination across all programs.8Internal Revenue Service. Instructions for Form 1023
Private schools must also keep records for at least three years documenting racial composition, evidence that scholarships are awarded without racial bias, copies of all fundraising solicitations, and copies of brochures, application forms, and catalogs related to admissions and financial aid. Failure to maintain these records creates a presumption of noncompliance and can jeopardize exempt status.8Internal Revenue Service. Instructions for Form 1023 Compliance must be certified annually, either on Schedule A of Form 990 or by filing Form 5578 if the school doesn’t file a 990.
State Sales Tax Exemption Certificates
Federal tax-exempt status and state sales tax exemption are separate. An IRS determination letter does not automatically exempt a school from paying sales tax at the register. Most states require a separate application through their department of revenue, and the federal determination letter is typically a required attachment to prove nonprofit status.
Application processes and resulting certificates vary. Some states issue a certificate of exemption with a unique state tax-exempt identification number; others accept a blanket exemption form the school fills out for each vendor. Most states charge no fee for the application itself, and many complete online reviews within a few weeks.
What the Certificate Covers
Certificates generally apply only to purchases made in the school’s official capacity for educational purposes: textbooks, lab equipment, classroom furniture, art supplies for student use. Purchases for personal use by staff members do not qualify. Items like food for staff events or electronics that could serve double duty sit in a gray area, and states draw the line differently.
Using a school’s exemption certificate for personal purchases is fraud. Individuals who knowingly issue a false or fraudulent exemption certificate can face financial penalties, fines, and jail time. Limit who has authority to use the certificate.
Expiration and Renewal
Exemption certificates do not last forever in every state. Some must be renewed annually, others last several years, and a few remain valid indefinitely as long as the information stays accurate. Check the specific renewal rule for your state. An expired certificate means the school pays full sales tax until it is renewed, and recovering that money after the fact is difficult.
Filings That Keep Federal Exempt Status Active
The determination letter is not the finish line. Tax-exempt schools must file an annual information return with the IRS. Which version depends on the school’s size:
- Form 990-N (e-Postcard) for schools with gross receipts of $50,000 or less.
- Form 990-EZ for schools with gross receipts under $200,000 and total assets under $500,000.
- Form 990 for schools with gross receipts of $200,000 or more, or total assets of $500,000 or more.
These thresholds apply across the Form 990 series.9Internal Revenue Service. Form 990 Series: Which Forms Do Exempt Organizations File An organization that fails to file for three consecutive years automatically loses its tax-exempt status, effective on the filing due date of the third missed return.10Internal Revenue Service. Automatic Revocation of Exemption
Automatic revocation is not just a paperwork problem. The school becomes a taxable entity and must file corporate income tax returns. Donors can no longer deduct contributions, and the school drops out of the IRS public database of eligible charities. Reinstatement requires filing a new application for exemption and paying the user fee again. State-level exemptions may also be affected, since many states tie their sales and property tax exemptions to active federal 501(c)(3) status.11Internal Revenue Service. Automatic Revocation of Exemption for Non-Filing: Frequently Asked Questions
Replacing a Lost Determination Letter
If the original IRS determination letter is lost or damaged, the school can file Form 4506-B to request either a copy of the most recently issued determination letter or a current affirmation letter confirming exempt status. Form 4506-B is submitted electronically.12Internal Revenue Service. Request for a Copy of Exempt Organization IRS Application or Letter Vendors, state agencies, and grantmakers ask for this letter often, so keep a secure digital copy.
Taxes a Tax-Exempt School Still Owes
Exempt status covers income tied to the school’s educational mission. Revenue from activities unrelated to education can still be taxed. Common examples include renting out facilities to outside businesses on a regular basis, selling advertising in school publications, or running a bookstore that sells merchandise unrelated to coursework.
If a school earns $1,000 or more in gross income from unrelated business activities during the year, it must file Form 990-T and pay tax on the net income at the standard corporate rate. Schools expecting to owe $500 or more must also make quarterly estimated tax payments. Form 990-T is separate from the annual Form 990 information return; the 990 reports overall operations, and the 990-T calculates tax on commercial activities. The test for whether an activity triggers the tax is whether it is regularly carried on and substantially unrelated to the school’s educational purpose.13Internal Revenue Service. Unrelated Business Income Tax
Payroll is the other place exempt status is often misunderstood. Schools with employees must withhold and pay FICA taxes (Social Security at 6.2 percent and Medicare at 1.45 percent of covered wages), matching the employee’s share. Federal income tax withholding based on W-4 forms also applies. The one payroll break is exemption from the Federal Unemployment Tax Act: payments made to employees of educational organizations described in Section 501(c)(3) are not subject to FUTA, so the school does not file Form 940 or pay federal unemployment tax.14Internal Revenue Service. Section 501(c)(3) Organizations – FUTA Exemption State unemployment tax rules vary and may still apply.
