Reporting changes to the IRS after 501(c)(3) approval

Your determination letter describes your organization as it was when you applied. Organizations grow and change: new programs start, boards rewrite bylaws, offices move, and sometimes a trust becomes a corporation. The IRS expects to hear about significant changes, but in most cases it wants to hear through your annual return, not a special filing. This guide sorts changes into three groups: report on the return, report on a separate form, and file a new application.

The general rule: report on your annual return

The Form 990 and 990-EZ instructions both say that new significant programs, significant changes in how you run programs, and significant changes to your organizing documents should be reported on the return, rather than in a letter to EO Determinations. EO Determinations no longer issues letters confirming exempt status after such changes.

Publication 557 adds that you may also tell EO Determinations about amendments, but that does not replace reporting them on the return.

Changes to your articles and bylaws

Your articles of incorporation (the document filed with the state that creates the corporation) and your bylaws (the internal rules) can be amended under state law and your own amendment procedures. See our guides to articles of incorporation and nonprofit bylaws.

Where to report. Form 990, Part VI, line 4, and Form 990-EZ, line 34, ask whether you made significant changes. Describe them on Schedule O. Do not attach the amended documents unless the change is a name change.

What counts as significant. The instructions list changes to:

• Your exempt purposes or mission
• Your name
• The number, composition, qualifications, authority or duties of voting board members, officers or key employees
• The role of members or stockholders in governance
• The distribution of assets on dissolution
• The amendment provisions themselves
• Quorum, voting rights or voting approval requirements
• Policies contained in the articles or bylaws on compensation, conflicts of interest, whistleblowers, or document retention
• The composition or procedures of an audit committee in those documents

What does not count. Changing your registered agent, or the number or frequency of meetings, is insignificant. A policy adopted by board resolution outside the bylaws, such as a standalone conflict of interest policy, is not reported on line 4 when it changes.

Changes in activities

Report new significant program services, significant changes in how you conduct them, and programs you stopped, on Form 990, Part III (lines 2 and 3) or Form 990-EZ, line 33, with a description on Schedule O.

Two cautions from Publication 557 matter here:

• Reliance. You cannot rely on your determination letter if there is a material change, inconsistent with exemption, in your character, purposes or method of operation. If the IRS later revokes for that reason, revocation ordinarily takes effect as of the date of the material change.
• Public charity status. A shift in how you are funded can change whether you pass a public support test. See public charity vs. private foundation.

Name changes

Annual return filers. Check the "Name change" box on your next Form 990 or 990-EZ and attach the supporting documents. For a corporation, that is a copy of the amendment to the articles and proof of filing with the state.

Form 990-N filers, or anyone who wants written confirmation. The IRS change-of-name page says you may report by letter or fax (not by phone) to Customer Account Services. Include the old and new names, your EIN, the supporting document, and the signature of an officer or trustee who states their title.

Affirmation letter. EO Determinations can issue an affirmation letter showing your new name and confirming your exempt status. Appendix A of Rev. Proc. 2026-5 lists no user fee for an affirmation letter reflecting a name or address change.

Address changes

The IRS change-of-address page says to report a new address on your next annual return (Form 990, 990-EZ or 990-N). You may also report it sooner on Form 8822-B or by calling IRS customer service, and you can request an affirmation letter with the new address. Even if you report it early, you must still show the change on your next return.

Responsible party changes

Your responsible party is the person named when you obtained your EIN, generally the principal officer who controls the organization's funds (see EIN for a nonprofit). Under Treasury Regulation 301.6109-1(d)(2)(ii), any entity with an EIN must report a change in its responsible party on Form 8822-B within 60 days of the change. The form says it generally takes 4 to 6 weeks to process. An officer must sign; a representative signing for you must attach a power of attorney.

When you need a new application

Changes of legal form. Rev. Proc. 2018-15 says a domestic exempt corporation that goes through a "corporate restructuring" usually does not need a new application if the surviving organization is a domestic corporation, carries out the same purposes, the restructuring organization is in good standing with its state, and (for a 501(c)(3)) the surviving organization's articles still meet the organizational test. Covered restructurings include:

• Incorporating an unincorporated association (which is already treated as a corporation for tax purposes)
• Reincorporating in a different state
• Domesticating a corporation in a new state
• A statutory merger of one corporation into another

Report the restructuring on your next Form 990. A reincorporation or domestication in another state also requires reporting your change of address.

When a new application is required. Rev. Proc. 2018-15 does not cover a restructuring in which either organization is an LLC, partnership, disregarded entity or foreign entity, or in which the surviving organization gets a new EIN. Its examples say a charitable trust that incorporates must file a new Form 1023, because a trust is not a business entity, and so must a corporation that converts into an LLC.

Changing to a different paragraph of 501(c). Under Rev. Proc. 2026-5, a 501(c)(3) seeking recognition under another paragraph, such as 501(c)(4), must apply, and must first have distributed its assets to another 501(c)(3) or a government entity.

Ending or merging. If your organization is dissolving or merging out of existence, see our dissolution guide. Publication 557 says a final return is due by the 15th day of the fifth month after the organization is liquidated, dissolved, terminated or substantially contracted.

Changing your fiscal year

Your fiscal year (tax year) is usually set in your bylaws and on your first return. To change it, the Form 990 instructions say you file a return for the short period, the stub period between the old year end and the new one, and indicate the change of accounting period in your filing software with the reason: either "Form 1128 was approved" or "Revenue Procedure 85-58 rules apply."

When Form 1128 is needed. You must also file Form 1128 with the short-period return if you changed your annual accounting period at any time within the 10-calendar-year period that includes the start of the short period, and you had a Form 990-series or income tax filing requirement during that time. Publication 557 says Form 1128 is due by the 15th day of the fifth month after the short period ends.

Form 990-N filers report a fiscal year change on Form 990, Form 990-EZ, or Form 1128, or by letter to the IRS, according to the Form 990 instructions.

Don't forget the states

Amendments to articles are filed with your state's corporations office, and many state charity regulators want copies of amendments, name changes and new addresses. Rules vary by state; see state annual reports and registered agents.
