2 CFR 200.400 and 200.401 Explained: The Federal Grant Cost Principles Every Grants Professional Must Know
Every federal grant question eventually comes down to the same handful of concerns: Is this cost allowable? Will an auditor question it? Do we have enough documentation to defend it? Before any of those questions can be answered, though, there's a more fundamental one to settle first: whose job is it to get this right in the first place?
That's exactly what 2 CFR 200.400 and 200.401 (the opening sections of Subpart E, Cost Principles, in the Uniform Guidance) are designed to answer. Together, they form the compliance baseline for every organization that receives federal funding, whether you're a university, a nonprofit, a local government, or a subrecipient several layers removed from the awarding agency.
What Is 2 CFR 200.400? The Policy Guide
2 CFR 200.400 sets the tone for everything else in the cost principles subpart. At its core, it establishes one non-negotiable point: whether you're a recipient or a subrecipient, your organization is responsible for the efficient and effective administration of federal awards through governance, compliance, and operational resiliency.
That responsibility does not belong to the federal agency. Agencies monitor grants, request reports, and follow up depending on whether you hold a grant or a cooperative agreement, but monitoring isn't the same as ownership. It doesn't belong to your auditor either, whose role is to test and sample costs after the fact. The accountability sits squarely with your organization, and specifically with its leadership, since sound internal controls and a fiduciary duty run from the top of an organization down to program staff.
What 200.400 Requires of Recipients and Subrecipients
Under this section, organizations receiving federal grants must:
Manage federal funds using sound management practices
Adhere to applicable laws, regulations, and the specific terms of each award
Keep accounting practices consistent and well documented, whether spending grant funds or the organization's own money
Apply cost principles consistently when negotiating indirect cost rates or cost allocation plans with a cognizant agency
A Few Practical Wrinkles Worth Knowing
200.400 also addresses situations that trip up even experienced grants staff:
Dual roles on research awards. Students supporting a research grant may need to be classified as trainees and employees, depending on the type of work they're doing. Both classifications matter when applying cost principles.
Program income and the no-profit rule. Recipients cannot treat leftover grant funds as profit unless the award's terms explicitly allow it. For example, if an organization receives a $50,000 fixed award and only spends $40,000 completing the work, the remaining $10,000 isn't kept. It goes back to the federal agency.
No two organizations are identical. Structure, staffing models, operational complexity, and indirect cost arrangements vary widely, which is why a cost that's indirect for one organization may be a direct cost for another. Uniform Guidance leaves room for management judgment here, but that judgment always has to be reasonable, consistent, and well documented, not a license to change your processes whenever it's convenient.
What Is 2 CFR 200.401? The Application
If 200.400 is the policy guide, 200.401 is the gatekeeper. It governs how those cost principles actually get applied. It explains that application depends on three things:
The nature of your organization
The terms and conditions of the specific federal award
Your organization's own written policies and procedures
This is where the Uniform Guidance makes clear that compliance is not one-size-fits-all. Every organization has different policies, travel limits, capitalization thresholds, and operational realities. A cost treatment that makes sense for a university may not make sense for a nonprofit or a local government, and the guidance is built to allow for that. Organizations are expected to use their own sound management practices and organizational techniques to hit their grant's goals and objectives, not copy a template designed for a different type of entity.
The Thread Connecting Both Sections: Consistency
If there's one theme running through 200.400 and 200.401 together, it's consistency. Auditors look for alignment between three things:
Your written policies and procedures
Your actual day-to-day practices
Your accounting records
When all three tell the same story, demonstrating compliance becomes far easier. In practice, it's often inconsistency (not the allowability of a cost itself) that leads to audit findings. A cost that's well documented, consistently applied, and backed by clear written policy can survive a challenge even if it initially looks questionable. That alignment, and the justification behind it, is frequently the deciding factor in whether a cost is ultimately treated as allowable.
Documentation Is the Deciding Factor
Most grants professionals have heard some version of the golden rule of auditing: if it isn't documented, it didn't happen. The reality under Subpart E goes a step further: if it's undocumented, it didn't happen, period. No one is going to accept that a cost is allowable without documentation or a clear justification for why it was deemed appropriate. A cost can look reasonable, allowable, and consistent on paper, but it's the justification behind it that often makes the difference when a cost is questioned.
Three Questions to Ask Before You Charge a Federal Grant
Before charging a single dollar to a federal award, run it through this filter:
Is it necessary?
Is it reasonable?
Does it align with the core policies in 200.400 and 200.401?
Every cost question an auditor raises is ultimately interpreted through these same foundational principles: Was the cost managed responsibly? Was it treated consistently? Was it supported by adequate policy and documentation?
Frequently Asked Questions
What is the difference between 2 CFR 200.400 and 200.401?
200.400 is the policy guide. It establishes that recipients and subrecipients, not the federal agency, are responsible for managing federal awards. 200.401 is the application section. It explains how those principles are applied based on an organization's nature, award terms, and written policies.
Who is responsible for compliance on a federal grant?
The recipient organization itself, starting with its leadership. Federal agencies monitor awards and auditors test costs, but day-to-day accountability for sound management and internal controls sits with the organization receiving the funds.
Can a nonprofit or grantee keep unspent federal grant money as profit?
No, not under standard terms. Federal grant funds are not intended to generate profit. Any unspent balance on a fixed award typically must be returned to the federal agency, unless the specific award terms state otherwise.
What usually causes federal grant audit findings?
More often than not, it's inconsistency, a mismatch between an organization's written policies, its actual practices, and its accounting records, rather than a cost simply being unallowable on its face.
Does every organization apply cost principles the same way?
No. The Uniform Guidance intentionally allows for differences based on an organization's structure, staffing, and operational complexity. A cost treatment appropriate for a university may not be appropriate for a nonprofit or local government.
Why does documentation matter so much for grant costs?
Because an undocumented cost is treated as if it never happened. Documentation, paired with a clear justification for why a cost was deemed necessary and reasonable, is often the deciding factor in whether a questioned cost is ultimately allowed.
Subpart E is not a set of optional guidelines. It's a mandatory compliance framework. Before charging any cost to a federal grant, the questions are always the same: Is it necessary? Is it reasonable? Does it align with 200.400 and 200.401? Mastering these fundamentals is what protects an organization's funding and makes the next audit far less stressful.
