Nonprofit CPA FAQs
Here are answers to common questions from boards, executive directors, and finance teams.
The single audit threshold rose to $1 million in federal expenditures, up from $750,000. It applies to fiscal years ending on or after September 30, 2025. Consequently some organizations that needed a single audit last year no longer do. Therefore it is worth recalculating before commissioning one.
Form 990 and Exempt Status
What is Form 990 and who must file it?
Form 990 is the annual information return that most tax-exempt organizations file with the IRS. In it you report financial information, governance, programs, and compliance details. Most 501(c)(3) organizations with gross receipts over $50,000 file Form 990 or 990-EZ, while smaller organizations file Form 990-N. However, failure to file for three consecutive years revokes tax-exempt status automatically.
When is the Form 990 deadline?
It falls on the 15th day of the fifth month after your accounting period ends. So a December 31 year end produces May 15, while a June 30 year end produces November 15. Form 8868 grants an automatic six-month extension, although it has to reach the IRS by the original due date. Meanwhile Form 990-N filers cannot extend at all.
How do nonprofits maintain 501(c)(3) tax-exempt status?
Maintaining 501(c)(3) status means operating within your exempt purpose, filing Form 990 annually, limiting lobbying and political activity, and also paying Unrelated Business Income Tax where applicable. Additionally it means keeping proper documentation of activities, finances, and governance.
What is UBIT and when does it apply?
Unrelated Business Income Tax applies whenever a nonprofit generates regular income from activities not substantially related to its exempt purpose. For example, advertising revenue, rental income with services attached, and commercial activities outside the mission all qualify. Organizations report it on Form 990-T.
Audits and Federal Awards
What is a single audit and which nonprofits need one?
A single audit under federal Uniform Guidance applies whenever a nonprofit expends $1 million or more in federal awards during a fiscal year. That threshold rose from $750,000 and applies to fiscal years ending on or after September 30, 2025. In addition, the engagement includes a financial statement audit plus a compliance audit covering federal program requirements, internal controls, and grant management.
When does a nonprofit need an audit?
Several triggers exist. First, state law sets thresholds that vary by state and revenue. Federal grant requirements bring in a single audit at $1 million in federal expenditures. Beyond that, funders, major donors, or board policy may require one. Finally, some nonprofits pursue voluntary audits to strengthen credibility with donors and regulators.
Do federal expenditures include pass-through funding?
Yes, although organizations regularly miss this when calculating. The threshold counts direct federal grants, state pass-through money, and subawards together. Furthermore it counts expenditures rather than awards received, so a multi-year grant is measured by what you actually spent in the fiscal year rather than the full award amount.
Accounting and Reporting
What is fund accounting and how is it different from regular accounting?
Fund accounting tracks resources by restriction and purpose, rather than focusing on profit. Nonprofits report net assets in two classes, either with donor restrictions or without them, following ASU 2016-14. Consequently this approach underpins grant compliance, donor stewardship, and accurate reporting to boards, funders, and regulators.
