2 CFR 200 Sections 407-411 Explained: The Real Audit That Cost One Nonprofit $1.5 Million
A federal auditor sits down with a nonprofit's books. By the end of the review, the organization is staring down two numbers: $45,000 in costs the auditor calls flatly unallowable, and $1.5 million in payroll costs the agency can't even determine are allowable, because the paperwork to prove it was never kept.
That is not a hypothetical. It's a real audit outcome, and it's a case study in exactly why 2 CFR 200 Sections 407 through 411 exist. These five sections of the Uniform Guidance govern prior approval, cost limitations, special considerations for different types of grant recipients, unallowable costs, and indirect cost rate adjustments. Together, they explain how a nonprofit ends up owing the federal government money it didn't expect to pay back.
Here's what every grants professional needs to know about these sections, using a real audit to show what went wrong and what could have prevented it.
Quick Answer: What Do 2 CFR 200 Sections 407–411 Cover?
2 CFR 200 Sections 407 through 411 are part of the Uniform Guidance's cost principles (Subpart E). They set the rules for when a federal grant recipient needs approval before spending, how much of a cost the federal government will actually pay for, how different types of organizations should treat direct and indirect costs, what happens when a cost turns out to be unallowable, and how unallowable costs affect a negotiated indirect cost rate.
Section 200.407 (Prior Written Approval): which costs and budget changes require the federal agency's written sign-off before you spend
Section 200.408 (Limitation on Allowance of Costs): what happens when a federal statute caps how much of a cost the award can pay, even if you spent more
Section 200.409 (Special Considerations): how direct vs. indirect cost treatment can differ across nonprofits, universities, states, and tribal organizations
Section 200.410 (Collection of Unallowable Costs): the recipient's obligation to refund costs an agency determines were not allowable
Section 200.411 (Adjustment of Previously Negotiated Indirect Cost Rates): how an unallowable direct cost can also force a correction to your indirect cost rate
The Case Study: A Nonprofit With Two Grants and One Bad Audit
The organization in question held two federal awards: a health grant and a capital improvement grant. When the funding agency audited both, it found two very different sized problems.
The smaller issue: $45,000 needed to be returned to the federal government: $4,000 tied to the health grant and $41,000 tied to the capital improvement grant. Not a small number for any nonprofit, but a contained one.
The much bigger issue: the agency identified $1.5 million in health grant payroll costs it could not confirm were allowable. The nonprofit was given two paths: refund the full $1.5 million outright, or work with the agency to determine, cost by cost, whether the spending could actually be justified.
The auditors' recommendations tell you exactly where the breakdown happened: train staff on charging costs to the correct period, improve support for salaries and wages, maintain personnel activity reports for employees working on federal awards, and follow internal policies for drawing down federal funds. Every one of those recommendations maps directly to Sections 407–411.
If a cost fails even one of these tests, it becomes unallowable, regardless of how well-intentioned the expense was or how directly it supported the project.
Section 407: Prior Written Approval and Why "We Have the Money" Isn't "We Have Permission"
Here's the trap grant managers fall into constantly: a budget has unspent funds in one line item, say an unfilled personnel position, and someone in finance decides to shift that money into equipment or travel. The logic feels sound: it's the organization's grant, the money is sitting there, so why not move it?
The problem is that availability of funds and authority to spend them are two different questions. Section 407 requires prior written approval for certain actions regardless of whether the budget technically has room, including:
Significant budget or program plan revisions
Purchasing certain equipment
Incurring costs in categories the award flags as requiring approval (participant costs, for example)
Before any expenditure like this, ask:
Is this cost specifically identified as requiring prior approval?
Does this award have terms that require approval for this type of change?
Is this a budget or program plan revision?
Section 408: Limitation on Allowance of Costs, or Why Spending It Doesn't Mean They'll Pay It
Section 408 addresses situations where a federal statute caps how much of a particular cost category the grant will reimburse, independent of what the organization actually spent.
Take the example directly from the audit: a nonprofit spends $100,000 on equipment. Nobody disputes that the money was spent. But the statute governing that award limits reimbursement for that cost category to $60,000. The organization cannot argue its way to full reimbursement by pointing at the invoice. The actual expenditure and the allowable federal charge are two separate numbers, and the remaining $40,000 has to be handled according to the award's other applicable requirements.
The lesson for grant managers: know your organization's budget and know the federal statutory limitations that apply to your specific award. They are not the same document, and confusing them is how a nonprofit ends up trying to bill for money the statute never authorized.
Section 409: Special Considerations and Why Documentation Is the Real Compliance Question
Federal awards don't go to one type of organization. States, local governments, tribal organizations, institutions of higher education, and nonprofits all receive them, and Section 409 recognizes that direct and indirect cost treatment can look different across each one. A university might have faculty splitting time across grants, institutional activities, and outside projects. A nonprofit might have staff dividing hours between a federal grant and a privately funded one. A state agency might run centralized administrative functions serving several programs at once.
What stays constant is the compliance question, and it's not "do we have payroll records?" Almost every organization has those. The real question is: can you demonstrate that the costs charged to a federal grant are actually connected to the work that grant is funding?
This is exactly where the $1.5 million in questioned costs came from. The nonprofit had payroll costs charged to its health grant, but it had not properly maintained personnel activity reports, the time-and-effort documentation that ties an employee's hours to the specific federal award. Without that record, the funding agency couldn't confirm the costs were allocable, so it treated the entire amount as questioned until proven otherwise.
Section 410: Collection of Unallowable Costs, When a Cost Just Can't Stay
Section 410 covers what happens once a cost is determined unallowable: the recipient doesn't get to keep it. It has to be addressed according to the federal agency's instructions and the award's terms, which typically means refunding the federal share.
This is the section behind the $45,000 finding. Unlike the $1.5 million payroll issue, this wasn't a documentation gray area. The audit determined outright that these specific costs did not meet federal cost principles, full stop. That's the key distinction to hold onto:
$45,000 = a straightforward unallowable-cost determination
$1.5 million = an allowability determination blocked by missing documentation
Both cost the organization money and both created audit risk, but they started from different root causes. The lesson underneath both: it is far easier to catch and resolve a questionable cost during the performance period than to reconstruct the justification for it during an audit, months or years later.
Section 411: Adjustment of Previously Negotiated Indirect Cost Rates
Unallowable costs don't stop causing damage once they're removed from a direct cost line. They can also force a correction to your negotiated indirect cost rate.
Here's the mechanic: say a $5,000 invoice was charged to a grant, drawn down, and later determined to be unallowable. The cost wasn't actually grant-related. The organization refunds the grant, crediting it $5,000 and shifting the expense to its own budget. But if that $5,000 also generated indirect cost recovery (say a 15% de minimis rate), the grant was charged an additional $750 in indirect costs tied to that now-unallowable expense. That $750 needs to be corrected too. The organization isn't just reimbursing the direct cost; it's reimbursing the indirect cost rate calculation built on top of it.
That's why a grants professional's review can't stop at "was the invoice paid?" It has to ask whether the cost was allowable, allocable, reasonable, properly documented, charged to the correct award, and pre-approved when required.
The Checklist: What to Ask Before Your Next Audit
Instead of asking "do we have payroll records?", a question almost every organization can answer yes to, ask the question that actually predicts audit outcomes:
Can our documentation show why this employee's time or compensation belongs on this specific grant?
Did we get written approval before making this budget change or incurring this cost category?
Do we know the statutory cost limitations that apply to this specific award, not just our internal budget?
Have we checked whether an unallowable direct cost also requires an indirect cost rate adjustment?
Are we correcting questionable costs now, during the performance period, instead of reconstructing them at audit time?
FAQ: 2 CFR 200 Prior Approval and Unallowable Costs
What is "prior written approval" under 2 CFR 200.407? It's a requirement that certain costs and budget or program changes, such as major budget revisions, specific equipment purchases, or cost categories flagged by the award, receive the federal agency's written sign-off before the recipient spends the money. Verbal approval does not satisfy this requirement.
What happens if an organization spends more than a federal statute allows under 2 CFR 200.408? The recipient can only be reimbursed up to the statutory limit, regardless of the actual amount spent. Any amount above that cap must be handled according to the award's other applicable requirements. It cannot simply be billed to the federal grant.
Why do personnel activity reports matter so much under 2 CFR 200.409? Because payroll and fringe benefit costs charged to a federal grant have to be demonstrably connected to work performed on that grant. Without personnel activity reports or time-and-effort documentation, an agency cannot confirm allocability, which is exactly how a nonprofit can end up with millions of dollars in "questioned" costs even if the spending itself may have been legitimate.
Can an unallowable direct cost affect an organization's indirect cost rate? Yes. Under 2 CFR 200.411, if an unallowable cost was included in the pool used to calculate a negotiated indirect cost rate, the rate itself may need to be adjusted or refunded, not just the original direct cost.
What's the difference between an unallowable cost and a questioned cost? An unallowable cost (2 CFR 200.410) has been determined not to meet federal cost principles and must be refunded. A questioned cost is one an agency hasn't yet been able to confirm as allowable, often due to missing documentation, and may ultimately be found allowable, partially allowable, or unallowable once the recipient provides support.
Know the Rule. Know the Award. Document Your Decision.
The throughline across all five sections is the same: documentation is not a clerical afterthought. It's often the single factor that determines whether a cost is allowable at all. A federal agency, an auditor, or a pass-through entity can't take an organization's word for it. They need the paper trail.
Before your next audit, don't stop at confirming records exist. Confirm they can actually answer the question an auditor will ask: why does this cost belong on this grant?
