A nonprofit’s accounting obligations run on two tracks that meet at year end: a set of financial statements prepared under FASB rules, and the underlying records that support them. Nonprofit financial statements and accounting records must together show what the organization owns, what it owes, where its money came from, where it went, and how much of each dollar reached the mission. Get the presentation and the recordkeeping right and the annual Form 990, any required audit, and public-inspection requests all fall into place. Get them wrong and the organization risks penalties, disallowed deductions for its donors, and in the worst case automatic loss of tax-exempt status.
The Four Financial Statements a Nonprofit Must Prepare
FASB Accounting Standards Codification Topic 958 sets the presentation framework. A complete set of nonprofit financial statements has four parts.
The Statement of Financial Position is the nonprofit equivalent of a balance sheet. It lists assets, liabilities, and net assets at a single date, and it tells stakeholders whether the organization has the resources to keep operating.
The Statement of Activities is the income statement. It reports revenue and expenses over the fiscal year and shows whether the year ended in surplus or deficit. Donations, program fees, and investment returns appear as separate revenue streams so that donors and regulators can see where the money is coming from.
The Statement of Cash Flows tracks actual cash movement across operating, investing, and financing activities. An organization can post a surplus on its Statement of Activities and still run short of cash if revenue is tied up in pledges or restricted accounts, and this statement is what catches that.
The fourth piece comes from ASU 2016-14: an analysis of expenses by both nature (salaries, rent, supplies) and function (program services, management, fundraising). It can stand alone as a Statement of Functional Expenses, sit inside the Statement of Activities, or appear in the notes. The organization also has to disclose the methods it uses to allocate shared costs across functions, and apply those methods consistently year to year.
How Net Assets Are Classified
ASU 2016-14 collapsed net asset reporting into two categories. Every dollar in net assets belongs in one bucket or the other, and mixing them is a fast route to a compliance problem.
Without donor restrictions covers funds the board can spend on any purpose consistent with the mission. General donations, service fees, and investment income on unrestricted balances go here.
With donor restrictions covers anything that came in with strings attached. Some restrictions are temporary, like a grant earmarked for a specific project or a gift usable only after a set date. Others are perpetual, most commonly endowment principal that must stay intact while only the earnings can be spent. Restricted pools have to be tracked separately in the accounting system. Spending restricted funds on unauthorized purposes can trigger donor lawsuits and cut off future funding.
The Accounting Records Behind the Statements
The statements are only as reliable as what sits under them. The general ledger records every transaction in chronological order and forms the backbone of the system. Subsidiary journals capture specific activity: payroll, accounts payable, receivables. Underneath those are the original source documents — bank statements, canceled checks, paid invoices, receipts — that auditors will trace individual transactions back to when they test whether an expenditure was legitimate and properly authorized.
Contribution records carry extra weight because they have legal consequences for donors as well as the organization. Grant award letters, donor correspondence, and records of non-cash gifts like stock or real estate all need to be kept. For any single donation of $250 or more, the nonprofit must give the donor a written acknowledgment that names the organization, states the cash amount or describes the non-cash property, and says whether any goods or services were provided in return. Without that acknowledgment, the donor cannot claim a tax deduction.1Internal Revenue Service. Charitable Contributions Written Acknowledgments
When property rather than cash comes in, extra rules apply. For any non-cash gift the donor values above $5,000, the donor must obtain a qualified appraisal from a qualified appraiser and report the donation on IRS Form 8283. The nonprofit should keep its own records of these gifts and the acknowledgments it issued, because a mismatch between the organization’s records and the donor’s return can invite IRS scrutiny of both.2Internal Revenue Service. Instructions for Form 8283
Internal Controls Over the Records
Records without controls invite manipulation. The core principle is segregation of duties: no single person should control two or more phases of a financial transaction. Whoever opens the mail and handles incoming checks should not also record deposits in the accounting system. Whoever makes journal entries should not also sign checks. And someone independent of both should review the monthly bank statements. Small nonprofits can achieve adequate separation by assigning oversight roles to board members or volunteers. The point is not bureaucracy; it is making sure fraud requires collusion rather than one person’s decision.
Annual IRS Filing: Form 990
Most tax-exempt organizations must file an annual information return with the IRS. The version depends on size:
- Form 990-N (e-Postcard): gross receipts of $50,000 or less.
- Form 990-EZ: gross receipts under $200,000 and total assets under $500,000.
- Form 990: gross receipts of $200,000 or more, or total assets of $500,000 or more.
- Form 990-PF: all private foundations, regardless of size.
The return is due by the 15th day of the 5th month after the end of the fiscal year. For a calendar-year nonprofit, that is May 15. A six-month extension is available, but the 990-N cannot be extended.4Internal Revenue Service. Return Due Dates for Exempt Organizations Annual Return
Late filing carries financial penalties. Organizations with gross receipts under $1,208,500 face $20 per day, capped at $12,000 or 5 percent of gross receipts, whichever is less. Larger organizations pay $120 per day, up to $60,000.5Internal Revenue Service. Filing Procedures Late Filing of Annual Returns
The bigger risk is automatic revocation. Any organization that fails to file for three consecutive years loses its exempt status automatically on the original due date of the third missed return. Reinstatement requires a new application, and donations received during the revocation period may not be deductible for donors.6Internal Revenue Service. Automatic Revocation of Exemption
Records the Public Can Demand to See
Under IRC Section 6104, a 501(c)(3) must let anyone who asks inspect its three most recent Forms 990 and its original tax-exemption application, including Form 1023 and supporting materials.7Office of the Law Revision Counsel. 26 USC 6104 – Publicity of Information Required From Certain Exempt Organizations and Certain Trusts
In-person requests must be filled the same day during regular business hours at the principal office. Written requests must be answered within 30 days.8eCFR. 26 CFR 301.6104(d)-1 An organization that posts its Form 990 on its own website or a widely available third-party database does not have to fulfill individual written requests for copies, though it still has to allow in-person inspection.9Internal Revenue Service. Public Disclosure and Availability of Exempt Organization Returns and Applications Failing to comply carries a penalty of $20 per day the failure continues, up to $10,000 per return.10Office of the Law Revision Counsel. 26 USC 6652
How Long Records Must Be Kept
There is no single federal retention schedule for all nonprofit records, but widely accepted practice runs in three tiers. Organizational documents (articles of incorporation, bylaws, the original Form 1023, external audit reports, insurance records) should be kept permanently. Tax records, including Form 990 and its supporting documentation, should be retained for at least seven years from the filing date. Personnel files and performance reviews generally warrant seven years; job applications can be discarded after three.
What matters more than the schedule is what happens when destruction goes wrong. Under 18 U.S.C. § 1519, destroying, altering, or falsifying any document to obstruct a federal investigation or official proceeding is a crime, with fines and up to 20 years in prison.11Office of the Law Revision Counsel. 18 USC 1519 Any organization that learns a federal investigation is underway or imminent must halt routine destruction immediately. A written retention and destruction policy adopted by the board is the strongest protection, because it shows that any disposal followed a pre-existing schedule rather than a reaction to trouble.
When an Independent Audit Is Required
GAAP itself does not require nonprofits to undergo independent audits.12Financial Accounting Foundation. GAAP and Not-for-Profits The mandates come from elsewhere. The most common federal trigger is the Single Audit requirement under the OMB Uniform Guidance: a nonprofit that spends $1,000,000 or more in federal awards during its fiscal year must undergo a Single Audit examining both its financial statements and its compliance with federal grant terms. That threshold rose from $750,000 for fiscal years beginning on or after October 1, 2024.13U.S. Department of Health and Human Services Office of Inspector General. Single Audits Frequently Asked Questions Many states require audited financial statements above their own revenue thresholds, and grantors, lenders, and major donors often impose audit conditions of their own. Below any mandatory threshold, an annual financial review or compilation by a CPA still gives funders confidence and flags bookkeeping problems before they compound.
Two Boundaries the Accounting System Has to Handle
Tax-exempt status does not mean all income is untaxed. Income from a trade or business that is regularly conducted and not substantially related to the exempt purpose is subject to unrelated business income tax. A museum gift shop selling educational materials tied to exhibits is fine; the same shop selling generic clothing is not. Any organization with $1,000 or more in gross income from unrelated business activities must file Form 990-T,14Internal Revenue Service. Instructions for Form 990-T and the income is taxed at the standard corporate rate, currently 21 percent, under IRC Section 511.15Office of the Law Revision Counsel. 26 USC 511 Each unrelated activity has to be tracked separately in the books. Shared expenses like rent or utilities need a reasonable allocation method; if the organization cannot show which costs relate to the unrelated activity, the IRS may disallow the deductions entirely.
The other accounting slot to watch is insider transactions. IRC Section 4958 imposes excise taxes on any “excess benefit transaction” between the organization and a “disqualified person,” a category that includes officers, directors, key employees, and their family members. The insider who receives the excess benefit owes an initial tax of 25 percent of the excess, rising to an additional 200 percent if the transaction is not corrected within the taxable period. Managers who knowingly approve the transaction face a 10 percent tax, capped at $20,000 per transaction.16Office of the Law Revision Counsel. 26 USC 4958 The board’s protection is documentation: gather comparable market data before approving compensation or major insider transactions, have disinterested members make the decision, and record the basis in the minutes. That process creates a rebuttable presumption of reasonableness and shifts the burden to the IRS to prove otherwise.
