Top 5 Mistakes on 1023 Nonprofit Applications

Filing for 501(c)(3) status with the IRS is one of the most important steps in launching a nonprofit organization. The Form 1023 (or 1023-EZ, depending on eligibility) is what determines whether your nonprofit will be recognized as tax-exempt — giving you access to grants, donor contributions, and credibility in the community.

But here’s the reality: many applications are delayed, denied, or flagged for extra review because of common mistakes that could have been avoided. At All Things Business, we’ve helped nonprofits successfully navigate the 1023 process, and we’ve seen firsthand the pitfalls new organizations fall into.

Here are the top 5 mistakes to avoid on your 1023 nonprofit application.

1. Vague or Incomplete Purpose Statement

The IRS wants to clearly see that your nonprofit’s mission fits within charitable, educational, religious, or other 501(c)(3)-approved purposes. Too often, applicants write vague mission statements that don’t align with IRS criteria.

👉 Example of a weak statement: “We help people in need.”👉 Example of a strong statement: “We provide transitional housing, job readiness training, and supportive services to homeless veterans.”

Pro tip: Be clear, specific, and show how your programs directly serve the public good.

2. Missing or Weak Bylaws and Governing Documents

Your bylaws are more than paperwork — they show the IRS how your organization will be governed. Missing conflict of interest clauses, unclear board structures, or copied-and-pasted templates can lead to red flags.

Pro tip: Draft bylaws that clearly outline board duties, decision-making processes, and conflict of interest policies. Tailor them to your organization instead of using generic templates.

3. Inaccurate or Unrealistic Financial Projections

The IRS requires a budget for your first three years of operation. Many nonprofits submit either numbers that don’t add up, or projections that aren’t grounded in reality.

👉 Mistake example: Submitting a $500,000 budget with no clear revenue streams in year one.👉 Better approach: Start with realistic income (donations, small grants, program fees) and expenses (program delivery, admin, fundraising).

Pro tip: Show that your nonprofit has a sustainable financial model, even if you’re starting small.

4. Failing to Prove Public Benefit

The IRS denies applications if it looks like the nonprofit is set up to benefit a small group of insiders rather than the general public.

• Too many board members from the same family? Red flag.

• Programs described as “exclusive” or “private”? Red flag.

Pro tip: Highlight how your nonprofit benefits the broader community. Clearly separate board member roles from staff roles to avoid conflicts of interest.

5. Submitting an Incomplete or Rushed Application

The 1023 is long and detailed, and mistakes happen when organizations rush through it. Missing attachments, unsigned forms, or unchecked boxes are some of the most common errors that cause costly delays.

Pro tip: Review your application carefully, or have an expert double-check it before submission. Think of it as an investment — avoiding mistakes now will save you months of frustration later.
