To be a treasurer for a nonprofit, you take on the board seat responsible for the organization’s money: keeping the books, presenting financial reports to the board, meeting IRS filing deadlines, overseeing payroll tax deposits, and handling donor acknowledgments. The role is a fiduciary one, which means the law expects you to act carefully, honestly, and in the organization’s interest, and it can hold you personally responsible when certain things go wrong.
The Fiduciary Duties You Accept
Three duties define the legal obligations of every nonprofit officer. The duty of care means you make informed decisions, read the financial reports before you vote on them, and ask questions when something looks off. The duty of loyalty means you disclose conflicts of interest and never use the organization’s resources for personal benefit. The duty of obedience means you make sure the nonprofit follows its own bylaws, stays inside its stated mission, and complies with federal and state law. Violating any of these can expose you personally and put the organization’s exempt status at risk.
Eligibility is straightforward in most states. Officers generally must be at least 18. Many jurisdictions allow one person to hold multiple officer positions, though some prohibit combining the president and treasurer roles to preserve financial checks. Prior convictions for embezzlement, fraud, or similar financial crimes commonly disqualify a person from a fiduciary role under state law. If the nonprofit receives federal grants, federal regulations set up a debarment and suspension system that can disqualify individuals from grant-funded programs, and checking the federal nonprocurement list before appointing a treasurer is worth doing.1eCFR. 22 CFR Part 513 – Government Debarment and Suspension (Nonprocurement)
What the Job Actually Involves
Day to day, the work is about keeping the books accurate and making sure the board has enough financial information to decide anything intelligently. You maintain current ledgers, reconcile bank accounts, and prepare an annual operating budget that reflects program goals and realistic revenue.
You give the board regular financial statements: a statement of financial position (the nonprofit’s balance sheet), a statement of activities (revenue minus expenses), and a statement of functional expenses that splits costs into program services, management, and fundraising. Board members without financial backgrounds will look to you to translate those reports into plain summaries they can act on.
If the nonprofit has employees, you oversee timely deposit of federal employment taxes, including income tax withholding, Social Security, and Medicare. This is the single area where a treasurer is most likely to face personal liability, so it deserves close attention even when a bookkeeper handles the mechanics.
Many states require an independent audit once annual revenue crosses a threshold. Those thresholds vary widely, running roughly from $500,000 to $2 million depending on the state and how it defines revenue. You coordinate with the external auditors and make sure the organization produces whatever level of financial review its state requires.
The IRS Filings You Own
Every tax-exempt organization must file an annual return or notice with the IRS unless a specific exception applies.2Internal Revenue Service. Form 990 Resources and Tools Which form depends on size:
- Form 990-N, the electronic e-Postcard, for organizations with gross receipts normally $50,000 or less. It is a brief notice, not a full return, and cannot be extended.3Internal Revenue Service. Form 990-N (e-Postcard)
- Form 990-EZ for organizations with gross receipts under $200,000 and total assets under $500,000.4Internal Revenue Service. 2025 Instructions for Form 990-EZ
- Form 990 when gross receipts reach $200,000 or total assets reach $500,000.4Internal Revenue Service. 2025 Instructions for Form 990-EZ
For a calendar-year organization, the initial deadline is May 15, and an automatic six-month extension pushes it to November 15.5Internal Revenue Service. Return Due Dates for Exempt Organizations Annual Return Fiscal-year filers have corresponding deadlines calculated as the 15th day of the fifth month after year-end.
Tax-exempt status does not cover every dollar coming in. If the nonprofit earns $1,000 or more in gross income from a regularly conducted trade or business unrelated to its exempt purpose, it must file Form 990-T and pay tax on that income.6Internal Revenue Service. Instructions for Form 990-T (2025) Common examples include advertising revenue in a nonprofit magazine, rental income from debt-financed property, and services that compete with for-profit businesses. Track those income streams separately so they can be flagged at tax time.
Donor Receipts and Public Disclosure
The treasurer usually owns the donor acknowledgment process, and the federal rules apply everywhere.
A donor cannot claim a deduction for any single contribution of $250 or more without a written acknowledgment from the organization. The acknowledgment must state the cash amount or describe any property contributed, say whether the organization provided any goods or services in return, and if so, give a good faith estimate of their value.7Office of the Law Revision Counsel. 26 U.S. Code 170 – Charitable Contributions and Gifts The donor must receive it before filing their return for the year of the gift.
When a donor pays more than $75 and receives something of value in return, such as a gala ticket, a tote bag, or an auction item, the organization must give the donor a written statement noting that only the amount above the fair market value of the benefit is deductible, along with a good faith estimate of that value.8Office of the Law Revision Counsel. 26 U.S. Code 6115 – Disclosure Related to Quid Pro Quo Contributions The disclosure belongs on the solicitation or the receipt.
Federal law also requires every exempt organization to make its exemption application (Form 1023 or 1023-EZ) and its annual returns available for public inspection. Annual returns must be available for three years starting from the later of the due date or the actual filing date.9Internal Revenue Service. Public Disclosure and Availability of Exempt Organizations Returns and Applications – Documents Subject to Public Disclosure Except for private foundations, organizations do not have to disclose individual donor names or addresses. If someone walks in or writes asking for the 990, produce it. Posting returns on the website satisfies the requirement for most organizations.
Where You Can Be Held Personally Liable
This is the part of the job worth reading twice before accepting.
Federal law lets the IRS hold any “responsible person” personally liable for unpaid employment taxes under the trust fund recovery penalty. The penalty equals 100 percent of the unpaid tax, meaning the IRS can collect the entire amount from you individually if you willfully failed to make sure it was paid. A treasurer with authority over the organization’s finances is a textbook responsible person. There is a narrow exception for unpaid board members who serve in an honorary capacity, do not participate in day-to-day financial operations, and have no actual knowledge of the failure, but a working treasurer almost never qualifies.10Office of the Law Revision Counsel. 26 U.S. Code 6672 – Failure to Collect and Pay Over Tax If the nonprofit has employees, confirming that payroll taxes are deposited on time is non-negotiable.
Filing Form 990 or 990-EZ late without reasonable cause triggers a penalty of $25 per day. For organizations with gross receipts under $1,309,500, the maximum is $13,000 or 5 percent of gross receipts, whichever is less.11Internal Revenue Service. 2025 Instructions for Form 990 These figures are inflation-adjusted, so check the current year’s instructions.
Failing to file any required annual return or notice for three consecutive years causes automatic revocation of the organization’s tax-exempt status.12Internal Revenue Service. Automatic Revocation of Exemption for Non-Filing Frequently Asked Questions This applies to every return, including the 990-N e-Postcard. Once revoked, the organization must reapply and pay the user fee, and donations received during the revocation period are not deductible for donors. A filing calendar with reminders is one of the simplest and most valuable things a treasurer can maintain.
Skills and Concepts to Have Before You Say Yes
You do not need a CPA to serve, but you need real financial literacy. The most important concept is fund accounting, the system nonprofits use to track money by source and by donor-imposed restriction rather than only by revenue and expense. A gift restricted to a scholarship program cannot be spent on office rent, and fund accounting is how you enforce that.
Familiarity with GAAP as applied to nonprofits helps you read and prepare accurate statements. Get comfortable with the statement of functional expenses, which splits spending into program services, management, and fundraising. Donors and the IRS both look at that split closely.
Understand internal controls: separation of duties, dual-signature requirements on checks above a threshold, and procedures that keep one person from both authorizing and executing a payment. Controls are what catch honest mistakes and deter dishonest ones before either becomes a crisis.
One legal concept every treasurer should understand deeply is private inurement. No part of a 501(c)(3) organization’s earnings may benefit any private individual who has influence over the organization.13Internal Revenue Service. Inurement/Private Benefit – Charitable Organizations That covers excessive officer compensation, sweetheart deals with vendors connected to board members, and loans to insiders on favorable terms. The treasurer is often the first person positioned to spot these, and the IRS can revoke exempt status over them.
Taking Over Cleanly
Before you take the finances, collect these from the outgoing treasurer or the board:
- The corporate bylaws, which define your authority, term length, spending limits, and what needs board approval.
- The last three years of Form 990 filings, which show the financial trajectory and any compliance issues you are inheriting.
- The EIN verification letter from the IRS, needed for banking and tax filings.
- The conflict of interest policy. Form 990 asks whether the organization has one, so most nonprofits do; review and sign it to document that you have no undisclosed financial relationships with the organization’s vendors.11Internal Revenue Service. 2025 Instructions for Form 990
- Current bank and investment statements, so you can see cash on hand, signatories, and outstanding obligations.
- The board resolution authorizing your signatory status. Banks require a certified copy before updating account access.
Board meeting minutes and Form 990 filings should be kept permanently. Bank statements and financial records should be retained for at least seven years, which covers the IRS statute of limitations for most situations.
The appointment itself starts with a recorded vote by the board at a properly noticed meeting, documented in the minutes with an effective date. Follow any quorum or nomination procedure in the bylaws exactly, because an improperly documented appointment causes problems later with banks and government agencies.
Then notify the IRS. This is where many new treasurers and boards slip. The IRS requires any entity with an EIN to report a change in its “responsible party” within 60 days by filing Form 8822-B.14Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party – Business The responsible party is typically the principal officer or the person who controls the organization’s funds, often the treasurer. Filing is mandatory, and the 990 filed months later does not substitute for the 60-day notice.
Most states also require nonprofits to file periodic reports with the Secretary of State that include updated officer information. Frequency and fees vary. Handle the state filing promptly after the board vote, because outdated officer information can hold up bank account changes and grant applications.
Finally, update the bank. In most cases you will need to visit in person with government-issued identification and a certified copy of the board resolution. Remove the outgoing treasurer as a signer at the same time, and update online banking credentials.
Protecting Yourself
Federal law gives volunteers a layer of personal liability protection. Under the Volunteer Protection Act, a volunteer is not liable for harm caused by their acts or omissions as long as they were acting within the scope of their responsibilities, the harm was not caused by willful or criminal misconduct, gross negligence, or reckless behavior, and the act did not involve operating a vehicle.15Office of the Law Revision Counsel. 42 USC 14503 – Limitation on Liability for Volunteers Punitive damages against a volunteer require clear and convincing evidence of willful misconduct. The protection applies to unpaid treasurers, does not shield the organization itself, and disappears the moment conduct crosses into recklessness or intentional wrongdoing.
Even with the statute, defending a lawsuit is expensive regardless of the outcome. Directors and Officers insurance covers legal defense costs and settlements arising from claims against board members and officers for alleged wrongful acts in that capacity. For a treasurer, that can include allegations of financial mismanagement, breach of fiduciary duty, or regulatory violations. D&O policies typically cover directors, officers, employees, and volunteers under a broad definition of insured persons. If the nonprofit does not already carry D&O coverage, raising it with the board is one of the most useful things you can do when you take the role.
