Nonprofit Compliance Guide

Running a nonprofit involves more than a mission, a board, and a budget. Once an organization forms and receives tax-exempt status, it takes on ongoing compliance responsibilities at the federal, state, and organizational levels to keep it running.

The exact requirements depend on factors such as your organization’s state, tax-exempt classification, revenue, activities, fundraising footprint, and whether you have employees. 

This guide is a practical starting point and compliance checklist. When requirements are unclear, or your organization has unusual circumstances, consult the appropriate professional or state agency.

What Is Nonprofit Compliance?

Nonprofit compliance is the ongoing process of meeting the legal, financial, tax, governance, and reporting obligations that apply to your organization.

Those obligations generally come from three places:

• Federal: The IRS sets requirements for maintaining federal tax-exempt status and reporting certain financial and operational information.
• State and local: Some states require corporate reports, charitable donation records, tax-exemption applications, employment information, and other intermittent reports.
• Internal governance: Your nonprofit must also operate under its own bylaws, board-approved policies, contracts, and organizational procedures.

Compliance is broader than simply filing Form 990 once a year. A nonprofit can submit its federal return on time and still have an overdue state registration, outdated corporate information, missing board records, or inadequate financial documentation.

The requirements also vary considerably by organization. A small, volunteer-run charity may have a relatively simple compliance calendar, while a larger foundation may have additional tax, investment, employment, grantmaking, and reporting obligations.

Nonprofit Compliance Checklist: Annual Requirements

Your nonprofit’s exact checklist will depend on its structure and activities, but these are the areas organizations should review regularly.

Customize this checklist rather than treating it as a universal list. For example, a nonprofit that operates in several states may have significantly more state-level obligations than one that operates and fundraises in only one state.

Federal Compliance: IRS Form 990 And Tax-Exempt Status

For many nonprofits, the annual IRS filing is the centerpiece of their federal compliance calendar. Here are some key things to remember: 

1. Know which Form 990 applies. The right form depends on the organization’s size and type. Organizations generally must file Form 990, but smaller organizations that fall below certain financial thresholds may have different requirements. Nonprofits must confirm their specific filing requirement with the IRS or a qualified tax professional to maintain their tax-exempt status.

2. Track the Form 990 deadline. For most organizations required to file an annual return, the deadline is the 15th day of the fifth month after the end of the organization’s tax year. A calendar-year organization, for example, generally has a May 15 deadline. The Form 990 series also allows organizations to request an extension in appropriate circumstances. An extension gives you additional time to file; it does not eliminate the filing requirement.

3. Don’t overlook Form 990-N. Smaller nonprofits sometimes assume that having little revenue means they have no annual IRS filing obligation. That is not the case. More importantly, failing to file a required Form 990, Form 990-EZ, or Form 990-N for three consecutive years results in automatic revocation of federal tax-exempt status. That makes the annual filing one of the most important recurring items on a nonprofit’s compliance calendar.

4. Watch for other federal filing obligations. Form 990 is not the only possible federal filing. Depending on its activities, a nonprofit may have additional reporting or tax obligations—for example, organizations subject to unrelated business income tax may need to file Form 990-T. Changes in activities, compensation arrangements, investments, fundraising methods, or organizational structure can also change required filings or disclosures. Revisit your filing requirements when the organization changes—not just at tax time.

State Compliance: Registration And Charitable Solicitation

Federal tax-exempt status does not automatically satisfy state compliance requirements. The state in which your nonprofit was incorporated may require annual corporate reports confirming and documenting whether your organization has employees, owns property, sells goods, or conducts fundraising activities. 

It’s important to note that charitable solicitation is a separate issue. One of the most commonly overlooked areas is charitable solicitation registration. Many states require nonprofits to register before soliciting donations from state residents. Still, the rules vary by jurisdiction, and fundraising through websites, social media, text messages, crowdfunding, and other online channels can raise questions about where registration is required.

Create a state-specific compliance list that records:

• Where the organization is incorporated.
• Where it operates.
• Where it has employees or other significant activities.
• Where it solicits charitable contributions.
• Which registrations or exemptions apply.
• Renewal deadlines and filing fees.
• The person responsible for each filing.

Governance And Financial Recordkeeping Requirements

Compliance goes beyond financial recordkeeping at the state and federal levels. Your nonprofit should also be able to show it operates responsibly and maintains records that support its activities and financial reporting.

That is why keeping governance records current is essential. Your articles of incorporation and bylaws establish important rules for how the organization operates. Maintain organized records of:

• Board and committee meetings
• Board decisions/resolutions 
• Elections and appointments
• Conflicts of interest and disclosures
• Major transactions
• Executive compensation 
• Amendments to governing documents

Maintain a reliable financial recordkeeping system. Your financial records should make it possible to explain where money came from, how it was spent, and how you calculated reported figures.

The IRS says exempt organizations must maintain books and records needed to demonstrate compliance with tax rules, including records supporting revenue and expenses reported on annual returns and other tax filings. 

That means maintaining organized documentation for items such as:

• Bank and investment accounts
• Donations and grants
• Restricted funds
• Payroll 
• Contractor payments
• Assets
• Reimbursements
• Credit card transactions
• Program expenses
• Major contracts and agreements

The IRS generally expects records supporting income, deductions, and credits to be retained for at least three years from the relevant filing date. However, other laws, contracts, organizational policies, or the nature of an asset may require longer retention.

Common Nonprofit Compliance Mistakes To Avoid

Even well-intentioned organizations can miss compliance requirements. The most common problems tend to come from treating compliance as a once-a-year task instead of an ongoing process.

1. Assuming Form 990 is the whole compliance picture. While your federal return matters greatly, it doesn’t replace state filings, charitable solicitation rosters, or other governance requirements.

2. Waiting until tax season to organize records. Attempting to reconstruct transactions, recite board decisions, remember donor information, or pinpoint restricted funds months after the fact is not only difficult to do, but also increases the risk of accounting and documentation errors.

3. Treating governance as paperwork. Board meeting minutes, conflict disclosures, and policy approvals create a record of how the organization makes decisions and manages potential conflicts.

4. Failing to update the compliance calendar when the organization changes. Expanding into another state, hiring employees, launching a new fundraising program, purchasing property, creating a new subsidiary, or starting an unrelated business activity can introduce new compliance obligations.

5. Assuming small organizations have no compliance responsibilities. Small nonprofits may have fewer filings, but they still need to maintain appropriate records and meet applicable requirements.

How To Stay Compliant Year-Round

The simplest approach is to turn compliance into a recurring management process rather than a scramble before deadlines.

• Build one master compliance calendar.
• Create a calendar containing every federal, state, and organizational deadline. Include:
  • Filing or renewal deadline
  • What must be submitted
  • Responsible person
  • Backup person
  • Required supporting documents
  • Review or approval date
  • Confirmation of submission
  • Next renewal date
• Set internal deadlines before the actual deadline so there is time to correct missing information or obtain signatures.
• Assign ownership. Compliance should not live entirely with one person.
  • Finance staff may own financial reporting and tax filings. 
  • Operations staff may manage corporate registrations. 
  • Fundraising staff may monitor charitable solicitation requirements. 
  • The executive director can coordinate the overall process, while the board provides oversight.
• Review compliance quarterly. A quarterly review can be as simple as asking:
  • What filings are due in the next 90 days?
  • Are any state registrations expiring?
  • Are financial records complete and reconciled?
  • Are board records up to date?
  • Are required policies and disclosures current?
• Keep documentation together. A centralized system for financial records, reports, approvals, and supporting documentation makes it easier to prepare filings and respond to questions.

For organizations that need stronger financial management infrastructure, MIP Accounting’s nonprofit accounting software provides tools designed to help nonprofit teams manage financial information and reporting in one system.

Most importantly, don’t treat compliance as a sign that something is wrong. It is part of responsible nonprofit management. A well-maintained compliance process gives staff, boards, donors, and other stakeholders greater confidence that the organization is operating in line with its obligations and mission.
