Federal grant obligation deadlines run on two clocks set by 2 CFR Part 200. First, every commitment charged to the award must be created inside the grant’s approved period of performance. Second, those commitments must be liquidated, meaning actually paid out, within 120 calendar days after the period of performance ends. Miss either deadline and the federal agency can disallow the costs and demand the money back, with interest and penalties layered on top.
What Counts as an Obligation
The Uniform Guidance defines financial obligations as orders placed for property and services, contracts and subawards made, and similar commitments that will require payment under the federal award.1eCFR. 2 CFR 200.1 – Definitions The operative word is commitment. An obligation is created the moment a legally binding agreement is formed, not when the bill gets paid. Signing a contract with a vendor in September creates an obligation in September, even if the vendor invoices in February.
That distinction between obligations and expenditures matters because the federal government tracks when the commitment was made, not just when the cash moved. A purchase order dated within the period of performance is a valid obligation. A verbal understanding with no signed agreement generally is not. Backdating a contract or assigning costs to a grant after the funding window closes leaves an audit trail auditors know how to read: the gap between the claimed obligation date and the documentary evidence.
Every dollar obligated also counts against the total award. An organization that signs contracts exceeding its award has created a liability it must cover from its own funds. Tracking obligations in real time, rather than waiting for invoices to trickle in, is the only reliable way to stay inside both the budget and the calendar.
The Period of Performance Window
Every federal grant specifies a period of performance, defined in the Uniform Guidance as the interval between the start date and end date of the award.2eCFR. 2 CFR Part 200 – Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards Those dates sit in the Notice of Award and function as hard boundaries. All costs charged to the grant must be incurred during the approved budget period, with only narrow exceptions for closeout costs and pre-award spending.3eCFR. 2 CFR 200.403 – Factors Affecting Allowability of Costs
The start date is the earliest point a recipient can commit federal funds to the project. Expenses before that date are generally unallowable without specific written approval. The end date is a firm cutoff for creating new obligations. Once it passes, no new contracts, purchase orders, or subawards can be charged to the grant. Anything outside the window becomes the recipient’s own financial responsibility.
Verify the exact dates on the Notice of Award before any project activity begins, and date-stamp every purchase request so the record shows the commitment fell inside the window. Basic housekeeping, but a common source of audit findings.
Pre-Award Costs: The 90-Day Look-Back
Sometimes a project needs to move before the official award document arrives. The Uniform Guidance lets recipients incur costs up to 90 calendar days before the federal award date without prior agency approval.4eCFR. 2 CFR Part 200 Subpart D – Post Federal Award Requirements These pre-award costs must be necessary for efficient and timely performance and must be the kind of cost that would be allowable if incurred after the start date.5eCFR. 2 CFR 200.458 – Pre-Award Costs
Costs incurred more than 90 days before the award date require written prior approval from the federal agency. Either way, pre-award spending happens at the recipient’s own risk. If the award never materializes or comes in smaller than expected, the federal government has no obligation to reimburse those early expenditures. When approved, pre-award costs must be charged to the initial budget period unless the agency specifies otherwise.
Some agencies extend or modify this window in their own terms. The Department of Education allows grantees under EDGAR Part 75 to incur expenditures up to 90 days before a grant begins without separate approval. Check the specific agency’s terms rather than assume the standard 90 days applies.
No-Cost Extensions to Move the End Date
When a project is running behind but still has unspent funds, a no-cost extension pushes the end date of the period of performance forward without adding federal money. Most federal awards allow the recipient to initiate a one-time extension of up to 12 months without prior agency approval, provided three conditions hold: no additional federal funds are needed, the project scope stays the same, and nothing in the award terms prohibits it.6eCFR. 2 CFR 200.308 – Revision of Budget and Program Plans
To exercise the one-time extension, the recipient must notify the federal agency in writing with supporting justification and a revised end date at least 10 calendar days before the current period of performance expires. Waiting until the last day is technically compliant but practically reckless. Agency systems may not process the notification in time, and any obligations created after the original end date could be disallowed.
Extensions beyond the one-time allowance, or those involving scope changes or additional funds, require prior written approval from the agency, and the request should go in at least 10 days before the period ends. An extension cannot be used solely to spend down leftover funds. The recipient must show that extra time is genuinely needed to complete project objectives.6eCFR. 2 CFR 200.308 – Revision of Budget and Program Plans
The 120-Day Liquidation Deadline
Once the period of performance ends, the work shifts from creating obligations to paying them off. Recipients must liquidate all financial obligations no later than 120 calendar days after the period of performance concludes.7eCFR. 2 CFR 200.344 – Closeout Liquidation means converting commitments into actual payments: issuing checks, paying final invoices, settling contractor bills. No new obligations can be created during this window. The only permitted spending is on commitments already in place before the end date.
All final reports, financial and performance, are also due within 120 calendar days after the period of performance ends.7eCFR. 2 CFR 200.344 – Closeout The key financial document is the Federal Financial Report (SF-425), which summarizes total expenditures, the federal share of costs, and any recipient cost-sharing contributions.8Grants.gov. Federal Financial Report (SF-425) – Form Items Description If the award funded tangible property, recipients may also need to file the SF-428 property report within the same 120 days.
Subrecipients: 90 Days, Not 120
Subrecipients face a tighter schedule. They must submit all reports and liquidate all obligations no later than 90 calendar days after the conclusion of their subaward’s period of performance, unless the pass-through entity agrees to an earlier date.9eCFR. 2 CFR 200.344 – Closeout The 30-day gap between the subrecipient’s 90-day deadline and the recipient’s 120-day deadline exists so the primary recipient has time to fold subrecipient data into its own closeout reports. A subrecipient that misses its window creates a cascading problem for the primary recipient’s ability to meet the 120-day cutoff. Pass-through entities should build the timeline into subaward agreements from the start.
Returning Unobligated Funds
Any unobligated funds the federal agency advanced but the recipient was not authorized to retain must be promptly refunded.7eCFR. 2 CFR 200.344 – Closeout After closeout reports come in, the agency makes final adjustments to the federal share of costs, which may include deobligating any remaining unliquidated balance. In practice, the agency reduces the award amount to match what was actually spent, and the recipient returns the difference.
Closeout does not end the recipient’s exposure. The federal agency retains the right to disallow costs and recover funds based on audit findings that surface after the award is formally closed.7eCFR. 2 CFR 200.344 – Closeout Records must be kept for at least three years from the date the final financial report is submitted, longer if litigation, a claim, or an audit is pending.10eCFR. 2 CFR 200.334 – Record Retention Requirements Repayment demands can arrive years after the project wraps.
Documenting the Obligation Date
Proving that an obligation occurred inside the period of performance requires dated, signed evidence. For procurement, that means executed contracts showing the agreement date and scope of work, along with signed purchase orders recording when goods or services were requested. For personnel costs, activity reports track actual hours worked on the grant-funded project. These are the primary exhibits in a federal audit.
Complete procurement files should include the original solicitation, the vendor’s response, and the final signed agreement, plus evidence the obligation was fulfilled, such as delivery confirmations or service logs. Electronic signatures are legally acceptable; federal law prohibits agencies from mandating a specific technology or requiring paper except in narrow law enforcement and national security circumstances.11Office of the Law Revision Counsel. 15 USC 7004 – Applicability to Federal and State Governments What matters is that every signature, wet ink or digital, carries a clear date.
What Happens When Deadlines Are Missed
When a recipient fails to meet obligation deadlines, liquidation requirements, or documentation standards, the federal agency has a graduated set of enforcement tools. If the problem cannot be fixed through specific conditions on the award, the agency may:12eCFR. 2 CFR 200.339 – Remedies for Noncompliance
- Withhold payments until corrective action is taken.
- Disallow specific costs or categories of spending, triggering repayment.
- Suspend or terminate all or part of the award.
- Initiate suspension or debarment proceedings, barring the recipient from future federal awards.
- Withhold future funding or continuation awards for the project or program.
Debarment is the most severe outcome and effectively ends an organization’s ability to participate in federal programs. Terminations for noncompliance must be reported in SAM.gov, where the record is visible to every federal awarding agency.13eCFR. 2 CFR 200.340 – Termination
Interest and Penalties on Repayment
When a recipient owes money back to the federal government, debt collection rules add financial charges on top of the principal. Interest accrues from the date the debt becomes delinquent, at a rate set annually by the Secretary of the Treasury, and that rate stays fixed for the life of the debt. After 90 days of delinquency, an additional penalty of up to 6 percent per year applies, plus the agency’s administrative costs for processing the collection.14eCFR. 31 CFR 901.9 – Interest, Penalties, and Administrative Costs
One narrow grace period exists: the agency must waive interest and administrative costs on any portion of the debt paid within 30 days of when interest began accruing. Partial payments apply first to penalties and administrative costs, then to interest, and finally to principal. Small partial payments may not reduce the underlying debt at all, which makes prompt resolution far cheaper than a drawn-out repayment.
