Compliance Isn't Optional
Earning your 501(c)(3) status is a major milestone — but it's not a finish line. Maintaining tax-exempt status requires ongoing compliance, and the consequences of falling behind can be severe: penalties, loss of exempt status, and damage to donor trust.
Here are the five most common compliance mistakes I see new nonprofits make — and how to avoid them.
1. Missing the Form 990 Filing Deadline
Every tax-exempt organization must file an annual return with the IRS. For most nonprofits, that's Form 990, 990-EZ, or 990-N (the e-Postcard), due by the 15th day of the 5th month after your fiscal year ends.
Why it matters: If you fail to file for three consecutive years, the IRS will automatically revoke your tax-exempt status. This is not discretionary — it's automatic.
How to avoid it: Set a calendar reminder 90 days before your filing deadline. Even if your organization is small, the 990-N e-Postcard takes just minutes.
2. Not Maintaining Board Minutes
Board meetings aren't just a governance formality — they create a legal record of your organization's decisions. The IRS expects to see regular, documented board activity.
Why it matters: Without minutes, you can't prove that major decisions (hiring, spending, program changes) were properly authorized. This becomes critical during audits or legal disputes.
How to avoid it: Hold at least quarterly board meetings and keep written minutes. They don't need to be lengthy — just accurate.
3. Ignoring State Filing Requirements
Your IRS determination letter is a federal document. Most states have their own requirements for nonprofits, including:
- State tax exemption registration
- Charitable solicitation registration (if you fundraise)
- Annual corporate reports with the Secretary of State
Why it matters: Falling behind on state filings can result in administrative dissolution of your corporation and loss of your state tax exemption.
How to avoid it: Research your state's specific requirements immediately after receiving your IRS determination letter. Set annual reminders for each filing.
4. Mixing Personal and Organizational Finances
This is one of the most dangerous mistakes a nonprofit can make. Using personal bank accounts for organizational transactions — or vice versa — creates serious legal and tax exposure.
Why it matters: Commingling funds can jeopardize your tax-exempt status, expose board members to personal liability, and make accurate financial reporting impossible.
How to avoid it: Open a dedicated organizational bank account immediately. All nonprofit income and expenses should flow through this account. Use accounting software from day one.
5. Operating Without Essential Policies
Many new nonprofits operate without basic governance policies, thinking they can add them later. The IRS and state regulators expect to see certain policies in place:
- Conflict of interest policy
- Whistleblower policy
- Document retention and destruction policy
- Compensation policy
Why it matters: These policies demonstrate good governance and protect your organization from internal disputes and external scrutiny. Many grant applications require them.
How to avoid it: Adopt essential policies at your organizational meeting, before you begin operations. Templates can help, but make sure they're customized for your organization.
Build a Compliance Culture Early
The best time to establish strong compliance practices is at the beginning. It's far easier to build good habits than to fix problems after they've compounded.
If you're unsure about your organization's governance and compliance health, a Governance Review can identify gaps and give you a clear action plan.
Frequently Asked Questions
What happens if a nonprofit doesn't file Form 990?
The IRS imposes a penalty of $20/day for late filing (up to $10,000 or 5% of gross receipts). For organizations with gross receipts over $1 million, the penalty is $100/day up to $50,000. After three consecutive years of non-filing, the IRS automatically revokes your tax-exempt status. Reinstatement requires filing all missed returns and reapplying.
How do I know if my nonprofit is in compliance?
Check these basics: Is your Form 990 filed and current? Is your state annual report filed? Are you registered for charitable solicitation in states where you fundraise? Do you have a conflict of interest policy, document retention policy, and whistleblower policy? Are board minutes being kept? If any of these are missing, you have a compliance gap.
Can a nonprofit operate without policies?
Technically you can operate without formal policies, but the IRS asks about several specific policies on the Form 990 — conflict of interest, document retention, whistleblower protection, and executive compensation. Answering "no" to these questions signals weak governance to the IRS, donors, and grant-makers. Essential policies should be adopted at your organizational meeting.
What's the most common reason nonprofits lose their tax-exempt status?
By far the most common reason is failure to file Form 990 for three consecutive years, which triggers automatic revocation. The IRS has revoked hundreds of thousands of organizations this way. The fix is simple: set a calendar reminder 90 days before your filing deadline and file on time, every time. Even the 990-N e-Postcard takes just minutes.
