Contract Closeout Procedures: Timelines, Files, and Final Payment

Contract closeout procedures are the final administrative steps a federal contracting officer takes to confirm every obligation under a contract has been met, settle remaining costs, deobligate excess funds, and archive the file. The Federal Acquisition Regulation sets the deadlines: simplified acquisitions close as soon as final payment clears, firm-fixed-price contracts should close within 6 months, contracts requiring indirect cost rate settlement have 36 months, and everything else has 20 months.¹ The clock only starts once the contract is physically complete, and it can be stopped cold by litigation, an open termination action, or a contractor who won’t submit the paperwork.

When the Closeout Clock Starts

A contract is not ready for closeout until it is physically complete. Under FAR 4.804-4, that means the contractor has delivered all required supplies and the government has inspected and accepted them, or the contractor has performed all required services and the government has accepted the work. Every option period included in the contract must also have expired.²

Two other paths reach the same result. The government can issue a notice of complete contract termination, which ends performance and starts closeout. For rental, use, and storage agreements, physical completion happens either through a termination notice or when the contract period expires.²

Watch the option-period trap. If the government chose not to exercise a remaining option, the contract is not physically complete until that option period actually expires on the calendar. A decision not to exercise is not the same as expiration, and until the date passes, the administrative clock has not started.

How Long You Have to Close a Contract

FAR 4.804-1 sets four timelines, all measured from the date the contracting officer receives evidence of physical completion.¹

Simplified acquisitions are considered closed as soon as the contracting officer has evidence of property receipt and final payment.
Firm-fixed-price contracts should be closed within 6 months.
Contracts requiring indirect cost rate settlement should be closed within 36 months.
All other contracts should be closed within 20 months.

The 36-month window for indirect cost contracts reflects the reality that the government often has to audit the contractor’s accounting records and negotiate final overhead rates, which routinely takes years. The 20-month category covers contract types like time-and-materials and labor-hour agreements that don’t require full indirect cost settlement but involve more complexity than a fixed-price deal.

Two hard exceptions override these timelines. A contract file cannot be closed while the contract is in litigation or under appeal. It also cannot be closed while a terminated contract still has unfinished termination actions.¹

What Has to Be in the Closeout File

FAR 4.804-5 lists fifteen specific actions the contract administration office must verify before a contract can be declared administratively complete. Missing one can stall the whole file. The requirements fall into four categories.

Financial settlement. The contractor’s final invoice must be submitted, and interim or disallowed costs must be settled. A contract funds review must be completed, and any excess funds must be deobligated. If the contract contained price revision provisions, that revision must be finalized. Prior-year indirect cost rates need to be settled before closeout proceeds.³

Property and intellectual property. Property clearance and a plant clearance report must confirm that government-furnished equipment has been returned or properly disposed of. A final patent report must be cleared, and a final royalty report is required when the contract involved licensed technology.³

Subcontracts and audits. The prime contractor must settle all subcontracts before the government can close the prime file. Outstanding value engineering change proposals must be resolved, any termination docket must be completed, the contract audit must be finished, and the contractor’s closing statement must be in hand.³

Release of claims. Contractors typically provide a release of claims alongside the final invoice, waiving the right to seek additional payments or damages after final settlement. That document protects the government from future disputes over the completed work.

DoD Closeout Forms

Department of Defense contracts use two standardized forms. DD Form 1597, the Contract Closeout Check-List, tracks each required clearance as it is completed, with lettered line items for actions like property clearance, plant clearance reports, and final voucher submission, each carrying a date-completed field.⁴

DD Form 1594, the Contract Completion Statement, is the summary document that formally closes the file. It captures the final payment voucher number and date, excess fund amounts in Block 5, and a certification in Block 9 where the responsible official attests that all administration actions have been fully and satisfactorily completed. The purchasing office signs off in Block 10 to close the file.⁵

Quick-Closeout for Indirect Costs

Waiting years for a full indirect cost audit on a small-dollar contract wastes time on both sides. FAR 42.708 lets a contracting officer negotiate and settle indirect costs on an individual contract without waiting for the contractor’s final rates to be established across all government work.

Two conditions apply. The contract must be physically complete, and the total unsettled direct and indirect costs allocated to the contract must be relatively insignificant, defined as the lesser of $1,000,000 or 10 percent of the total contract amount.⁶

Before using this authority, the contracting officer must perform a risk assessment covering the contractor’s accounting and estimating systems, any auditor concerns, the contractor’s history of approved indirect cost rates, and factors like mergers or unusual rate fluctuations. The contracting officer and contractor must agree on a reasonable estimate of the allocable costs.⁷

The trade-off is finality. Rates settled through quick-closeout are final for that specific contract only. No future adjustments account for over- or under-recoveries once the government establishes the contractor’s actual rates later, and those quick-closeout rates carry no precedential weight for other contracts.⁷

When the Contractor Won’t Cooperate

The biggest bottleneck in closeout is usually the contractor. Cost-reimbursement contractors must submit annual incurred cost proposals within six months after the end of each fiscal year.⁸ When those submissions run more than six months late, the Defense Contract Audit Agency will recommend that the contracting officer apply a decrement factor and issue a unilateral rate determination, establishing the rates without the contractor’s input.

Final invoices work similarly. If a contractor fails to submit a completion invoice within 120 days after final indirect cost rates are settled, or within a longer period the contracting officer approves, the contracting officer can unilaterally determine the amounts owed and record that determination through a contract modification.⁹

Patent silence is handled the same way. After notifying the contractor of its obligations and the government’s rights under the applicable patent clause, the contracting officer can consult agency patent counsel and close the file without the contractor’s cooperation.³

The Appropriation Cancellation Deadline

Closeout intersects with federal appropriations law in a way that can trump the FAR timelines. Under 31 U.S.C. § 1552, a fixed appropriation account is closed on September 30 of the fifth fiscal year after its period of availability for obligation ends. Any remaining balance, obligated or not, is cancelled and can no longer be used for any purpose.¹⁰

If a contract funded with a fiscal-year appropriation is still open when its appropriation account is cancelled, paying the contractor’s final invoice gets complicated fast. The paying office may need to use up to one percent of its current appropriation to cover the liability or seek a re-appropriation from Congress. Neither path is quick, which is why letting a file drag past the cancellation window creates problems that ripple across agency finance operations.

Past Performance Reporting at Closeout

Closeout overlaps with a Contractor Performance Assessment Reporting System obligation that is sometimes missed. A final past performance evaluation should be completed when the contract is finished or the last major deliverable is accepted. For contracts with option periods, the final report is prepared after performance ends under the last exercised option.¹¹

The full evaluation process, including the contractor’s 60-day comment period, must be completed within 120 calendar days after the performance period ends.¹¹ Agencies can also prepare addendum evaluations after the final report to document how the contractor performed during closeout itself, covering responsiveness to closeout requests, warranty performance, and similar administrative matters.

Final Payment and Record Retention

Once every checklist item is complete, the contracting officer processes final payment, deobligates any excess funds, and issues a contract completion statement to the accounting office. The Federal Procurement Data System is updated to record the final performance and closeout details.

For cost-reimbursement contracts, final payment is governed by FAR 52.216-7. Once the completion invoice is approved and the contractor has met all contract terms, the government pays the remaining balance of allowable costs and any unpaid fee. Before final payment, the contracting officer retains authority to audit invoices and reduce payments by amounts determined to be unallowable or to adjust for prior overpayments.¹²

After closure, the file moves to archival storage. FAR 4.805 requires contract files to be retained for six years after final payment.¹³ During that period, the records remain accessible to oversight agencies, inspectors general, and investigative bodies. When the retention period expires, the records are destroyed according to government disposal protocols.
