Nonprofit Tax Exemption: Complete Guide to Getting and Keeping It

Tax-exempt status is the legal foundation that makes nonprofit work possible. It allows organizations to receive tax-deductible donations, apply for grants, and operate without paying federal income tax on mission-related revenue. But getting tax exemption is only the first step. Keeping it requires ongoing compliance that many organizations neglect until it is too late.

What Tax Exemption Actually Means

Federal tax exemption under Section 501(c)(3) means:

• The organization does not pay federal income tax on revenue related to its exempt purpose
• Donors can deduct contributions on their personal or corporate tax returns
• The organization is eligible for foundation and government grants
• The organization may qualify for state tax exemptions, bulk mailing rates, and other benefits

What it does NOT mean:

• Exemption from employment taxes (payroll taxes still apply)
• Exemption from all state and local taxes (these require separate applications)
• Exemption from sales tax in all states (varies by state)
• Freedom from financial reporting (Form 990 filing is required annually)

Federal Tax Exemption: How to Get It

Step 1: Incorporate in Your State

File articles of incorporation with your state. The articles must include specific IRS-required language about exempt purpose and dissolution (assets must go to another 501(c)(3) upon dissolution).

Step 2: Obtain an EIN

Apply for an Employer Identification Number from the IRS. Free, online, immediate.

Step 3: Adopt Bylaws and Governance Policies

Bylaws govern how the organization operates. Essential governance policies include conflict of interest, document retention, and whistleblower. See our bylaws template guide.

Step 4: File for Federal Tax Exemption

File Form 1023 (full application) or Form 1023-EZ (streamlined) with the IRS. See our Form 1023 vs 1023-EZ comparison for guidance on which to use.

Step 5: Receive Your Determination Letter

The IRS issues a determination letter confirming your 501(c)(3) status. Keep this document permanently -- funders, banks, and government agencies will request it throughout your organization's life.

State Tax Exemptions: Separate Process

Federal tax exemption does not automatically extend to state and local taxes. Most states require separate applications for:

State income tax exemption. Many states automatically recognize federal 501(c)(3) status. Others require a separate application.

Sales tax exemption. Rules vary dramatically by state. Some exempt all nonprofit purchases. Others exempt only purchases directly related to exempt purpose. Some provide no exemption at all.

Property tax exemption. Generally available for property used directly for exempt purposes. Rental property and investment property typically do not qualify.

Charitable solicitation registration. Most states (approximately 40) require nonprofits to register before soliciting donations from residents of that state. This applies to online fundraising that reaches donors nationwide.

Maintaining Tax-Exempt Status

Annual Filing Requirements

Form 990-N (e-Postcard): Gross receipts normally under $50,000. Filed electronically, no financial data required.

Form 990-EZ: Gross receipts under $200,000 AND total assets under $500,000.

Form 990: All other organizations.

Due date: 15th day of the 5th month after the fiscal year ends (May 15 for calendar-year organizations).

See our Form 990 filing guide and annual filing requirements guide for detailed guidance.

Critical warning: Failure to file Form 990 for three consecutive years results in automatic revocation of tax-exempt status. This is not discretionary -- it is automatic. The IRS revokes approximately 300,000 organizations' status annually for this reason.

Operational Requirements

Operate exclusively for exempt purposes. Activities must further the charitable, educational, religious, or scientific mission.

No private benefit or inurement. No organizational earnings can benefit insiders (board members, officers, founders) beyond reasonable compensation for services.

Lobbying limits. Lobbying cannot be a substantial part of activities (or must stay within 501(h) election limits).

No political campaign activity. Absolutely prohibited for 501(c)(3) organizations.

Public disclosure. Must make Form 990, application, and determination letter available to the public upon request.

Common Reasons for Revocation

Failure to file Form 990 (3 consecutive years). The number one cause. Automatic, no warning.

Private inurement. Excessive compensation, sweetheart deals, personal use of organizational assets.

Substantial lobbying. Exceeding the limits without a clear defense.

Political campaign activity. Any amount can trigger revocation.

Operating for private benefit. Activities primarily benefit insiders rather than the public.

Unrelated business income. Excessive income from activities unrelated to exempt purpose without paying UBIT (Unrelated Business Income Tax).

Reinstating Revoked Status

If status is revoked for non-filing:

• File all missing Form 990s
• Submit a new application (Form 1023 or 1023-EZ) with the appropriate fee
• Include a reasonable cause statement explaining the failure to file
• If approved, reinstatement is effective from the date the new application was filed (not retroactive unless you qualify for retroactive reinstatement)

The process takes 3-12 months and costs $275-$600 plus any professional fees. Prevention is dramatically cheaper.

Tangible Takeaway

Put three dates on your calendar today: (1) Your Form 990 deadline (May 15 for calendar-year organizations). (2) Your state charitable solicitation renewal date. (3) A quarterly board compliance check where you verify that all filings are current. These three calendar entries prevent the most common compliance failures that cost organizations their tax-exempt status.

Frequently Asked Questions

How do I check if a nonprofit is tax-exempt? Search the IRS Tax Exempt Organization Search tool or Candid (GuideStar). See our check nonprofit status guide.

Does tax-exempt status expire? No, it does not have an expiration date. However, it can be revoked for non-compliance.

Can a for-profit convert to tax-exempt? It is legally possible but complex. The IRS scrutinizes these conversions carefully, particularly for fair market value asset transfers.

What is UBIT? Unrelated Business Income Tax applies when a tax-exempt organization regularly conducts business activities not substantially related to its exempt purpose. The tax rate is the standard corporate rate.

Do churches need to apply for tax exemption? Churches are automatically considered tax-exempt under 501(c)(3) and are not required to file Form 1023. However, many choose to apply to receive a determination letter for donor and funder confidence.

What about fiscal sponsorship? Organizations that have not yet received tax-exempt status can operate under a fiscal sponsor -- an existing 501(c)(3) that receives and manages funds on their behalf. See our fiscal sponsorship guide.

How much does it cost to maintain tax-exempt status? Filing Form 990-N is free. Form 990-EZ or 990 preparation by a CPA typically costs $500-$5,000+ depending on complexity. State registrations cost $25-$300 per state.

Can volunteers cause tax-exempt status problems? Unlikely, but volunteer activities that generate substantial unrelated business income or constitute political activity could create issues.
