If you have just joined a nonprofit finance team, or if you have been doing this work for a while but nobody ever gave you a proper explanation of fund accounting from the ground up, this is for you. The restricted versus unrestricted distinction sounds like accounting jargon, but it describes something very concrete: whether the organization gets to decide how money is used, or whether someone else already decided before the money arrived.
Getting this distinction wrong is the most common source of grant compliance problems at small nonprofits. It shows up in Single Audit findings, in funder relationship breakdowns, and in the kind of year-end scramble where a finance director spends three weeks reconstructing how expenses were coded before a federal reporting deadline.
What Restricted Funds Are
A restricted fund is money that came with conditions attached. The donor or funder specified, in writing, how the funds may be used. Those conditions are legally enforceable. If the money was intended for youth literacy programming, it can only be spent on youth literacy programming. If it was intended for capital improvements at a specific facility, spending it on operating expenses violates the grant agreement regardless of how urgent those operating expenses might be.
Restrictions come in two forms:
Purpose restrictions specify that money must be used for a particular program or activity. A federal workforce development grant that covers job training services for adults 25 and older has a purpose restriction. Money from that grant cannot be redirected to administrative overhead or a different program population without the funder's formal approval.
Time restrictions specify that money cannot be used until a certain date, or must be used before a certain date (the period of performance). Federal grants typically carry both: the funding is available from the award date through the end of the grant period, and unspent funds at the end of the period must be returned to the awarding agency unless a no-cost extension is approved.
A single grant agreement can carry both types simultaneously. A federal community development grant might restrict funds to housing-related services (purpose restriction) and require all funds to be expended within a 24-month project period (time restriction).
What Unrestricted Funds Are
Unrestricted funds have no donor-imposed conditions on their use. The organization's board and management decide how to allocate them. Individual charitable donations without a specific designation, general operating support grants, and membership dues are common examples of unrestricted revenue for nonprofits.
Board-designated funds are worth mentioning here because they create a frequent point of confusion. When a nonprofit's board votes to set aside a portion of unrestricted revenue for a specific purpose (a building reserve fund, for example), that money is board-designated. It is not donor-restricted. The board can reverse its designation by a subsequent vote. A donor restriction cannot be reversed by the organization unilaterally.
This distinction matters operationally because board-designated funds do not require the same audit trail that donor-restricted grant funds do. You do not need to document that board-designated reserves were spent in accordance with a funder's cost principles. You do need to document that federal grant funds were spent on allowable, allocable, reasonable costs as defined in 2 CFR Part 200 and the specific grant's Notice of Award.
Why This Matters at the Moment of Every Transaction
Here is where fund accounting theory becomes a daily operational problem. Every time a staff member makes a purchase using a card or requests a reimbursement, someone in the organization needs to know which fund that expense should be charged to. If the expense is charged to a restricted fund, the charge must comply with that fund's restrictions. If there is no restricted fund that covers the expense, it goes to unrestricted operating funds.
In practice, what happens at a typical small nonprofit is that employees have access to one or two cards without clear grant-level policies attached, and they charge whatever is convenient. The finance team then attempts to sort out the proper fund allocations at month-end using receipts and their knowledge of what each grant covers. This works reasonably well when:
- The organization has only one or two active grants
- The finance person knows all the grant restrictions by heart
- Employees always save their receipts
- No one makes purchases in unfamiliar spending categories
It breaks down predictably when any of those conditions is absent, which is most of the time for organizations managing multiple federal awards simultaneously.
The Accounting Treatment: Why Separate Fund Codes Matter
Nonprofit accounting standards (FASB ASC 958) require organizations to track net assets with donor restrictions and net assets without donor restrictions separately. This flows through to your chart of accounts and to how individual transactions are coded.
Practically, this means each restricted grant should have its own cost center, class, or fund code in your accounting system. When a transaction is charged to the wrong fund, the error shows up as a misallocation between restricted and unrestricted net assets. If the misallocation is material, it can require a restatement of financial statements. In a federal grant context, it generates questioned costs in a Single Audit.
Keeping separate fund codes for each grant is not optional if you are managing federal awards. The documentation standard under the Uniform Guidance requires that you be able to demonstrate which transactions were charged to each federal award, at the transaction level, for the entire grant period. A chart of accounts that lumps multiple grants into a single restricted fund code will not satisfy this requirement.
A Common Scenario Where the Lines Get Blurry
Consider a nonprofit that operates an adult education program funded by a state grant and a youth mentoring program funded by a federal workforce grant. Both programs use the same physical space, share administrative staff, and occasionally use the same supplies. How do you code shared costs?
This is the allocable cost question, and it is separate from the restricted versus unrestricted question, but they intersect. The shared costs are allocable to both grants if you can demonstrate a reasonable and documented methodology for splitting them. Typically this involves a cost allocation plan that specifies the basis for the split (square footage, headcount, hours of use, etc.) and applies it consistently.
What you cannot do is charge 100% of shared costs to one grant because it is easier. If your state grant covers more than its proportionate share of the shared costs, the excess is an unallowable cost under that grant, even if the unrestricted fund would have covered the remainder legitimately.
This is where the "allocable" requirement in 2 CFR Part 200 becomes concrete. A cost is allocable to a federal award if it benefits the award in proportion to the amount charged. The grant accounting question and the restricted versus unrestricted question are both ultimately about being able to demonstrate that relationship.
Getting to a Working Definition You Can Apply Daily
If you are onboarding into a nonprofit finance role, here is a working rule that will serve you well for the vast majority of transactions: before coding any expense to a restricted fund, confirm that the expense falls within that fund's stated purpose, within its time period, and in an amount that is reasonable relative to the grant budget. If you cannot confirm all three, code it to unrestricted funds and document why.
This is conservative, and intentionally so. Underspending a restricted grant within its period of performance is a manageable problem. The leftover funds get returned or carried forward based on your agreement terms. Overcharging a restricted grant with unallowable costs is an audit finding that generates corrective action obligations and can affect your organization's eligibility for future federal awards.
Fund accounting is not complex in its core logic. The complexity comes from managing many grants simultaneously, each with slightly different restrictions and cost principles. The finance management tools you choose should make it easier to hold that complexity at the individual transaction level, not harder.
