Causes
The "net credit" problem arises from the Department's handling of multi-funded invoices. Vendors are permitted to bill credits without a corresponding net debit disbursement at the service level. This introduces complexity into payment calculations and can lead to inaccurate obligation balances, especially when errors occur in the setup of Contract Line Item Numbers (CLINs) and Accounting Classification Reference Numbers (ACRNs). Data quality issues exacerbate these problems, resulting in improper payments. The second major driver is the practice of intentionally short-paying invoices when all line items cannot be fully paid. While seemingly counterintuitive, this is a calculated risk mitigation strategy. The Department aims to reduce the accrual of costly late payment interest penalties and, more broadly, to preserve government funds and maintain purchasing power to support the warfighter. This approach prioritizes a smaller, controlled underpayment to avoid potentially larger, uncontrolled financial losses.
While classified as "improper payments," these intentional underpayments are recognized and can be rectified in subsequent payments. The Department has determined that the strategic benefits (reduced late payment interest, preservation of funds, and sustained purchasing power) outweigh the negative impacts. This approach acknowledges the complexities of large-scale government procurement and balances payment accuracy with broader financial and operational considerations. The Department is committed to reducing the occurrence of short payments by improving upstream compliance.
Finally, the Commercial Pay - MOCAS program experiences issues related to unknown payments. An analysis is underway to determine the root causes, with a report detailing findings and preventative measures expected in February 2026. This analysis will inform the development of measurable Corrective Action Plans (CAPs) to address the root causes and reduce future unknown payments.

Prevention
A key corrective action, already in effect as of May 21st, 2025, involves a procedural change within MOCAS Operations. Recognizing that invoices with net credits at either the service or invoice level frequently contribute to improper payments, the MOCAS program now rejects and returns such invoices to vendors without processing. This preventative measure ensures that vendors take responsibility for maintaining accurate billing practices, requiring them to submit only invoices reflecting net disbursements. Vendors needing to return funds are directed to utilize Pay.Gov instead of incorporating credit amounts directly into invoices that do not result in a net debit. This clear delineation of processes improves accuracy and reduces the risk of misapplication of funds.
Furthermore, the Department is addressing the established practice of intentionally short-paying invoices when full payment is not possible due to funding constraints on specific line items. While the Department acknowledges the continued necessity of this practice in certain situations, ongoing efforts aim to significantly reduce its frequency. These efforts focus on proactive measures designed to eliminate the conditions that lead to short payments. Specifically, the Department is working to ensure that adequate funding is loaded into the accounting system prior to vendors invoicing, thereby minimizing instances where line items cannot be fully paid. Additionally, vendors are being encouraged to bill expiring or cancelling funds separately to improve the chances of timely payment and reduce the need for short payments. A quarterly analysis and reporting of short pay trends is underway beginning March 2026, with the goal of developing additional measurable Corrective Action Plans (CAPs) by April 2026 to address root causes and reduce future short pays.
The long-term success of these corrective actions relies on establishing and enforcing key data integrity standards. The Department’s Corrective Action Plan (CAP) for the Commercial Pay – MOCAS program emphasizes strengthening the implementation of, and ensuring ongoing compliance with, critical standards that underpin the contract payment process. These include: (a) (OSD) Procure-to-Pay (P2P) Handshakes, which ensure seamless and accurate data exchange throughout the P2P lifecycle; (b) Procurement Data Standards (PDS), promoting standardized data elements and formats to enhance data quality and interoperability; and (c) Standard Line of Accounting (SLOA), maintaining consistent and accurate financial reporting through adherence to the SLOA framework. The Department will prioritize routine audits of transactions and reporting to ensure vendors are adhering to the new requirements. Training will be routinely conducted to ensure ongoing compliance.
In addition to these measures, the Department is conducting in-depth analyses of both technically improper and unknown payment causes. A detailed analysis of payment errors, particularly focusing on PGI and DCMA realignment-related errors, is scheduled for completion in March 2026, with corrective actions for at least 50% of identified root causes to be implemented by April 2026. Similarly, an analysis of reported unknown payments is targeted for completion in February 2026, with additional measurable CAPs to address root causes expected by March 2026. Ongoing compliance monitoring will be performed to measure corrective action plan effectiveness and achieve sustained improvement in payment accuracy and integrity across the Department.
The DoW's Corrective Action Plan (CAP) for the Commercial Pay - MOCAS program is designed with a level of planned and completed actions that directly addresses the identified causes of improper and unknown payments, ensuring proportionality to the severity of the associated amounts and the occurrence rate of each root cause. The implementation of a process within MOCAS Operations to reject and not process invoices with net credits at the service or invoice level exemplifies this principle. While the frequency of these instances may be relatively low, the substantial dollar value of transactions processed through MOCAS means that even a small number of errors can result in a significant financial projected impact. Therefore, implementing a proactive measure to eliminate this specific type of improper payment, effective May 21st, 2025, is a proportional and necessary response, preventing potentially large-scale errors from occurring in the first place. The immediacy of the improvement resulting from this measure underscores its effectiveness in directly addressing a high-risk area.
Addressing the underlying weaknesses in OSD Procure-to-Pay (P2P) Handshakes, Procurement Data Standards (PDS), and Standard Line of Accounting (SLOA) usage represents a longer-term, strategic approach to mitigating improper payments. While the impact of these improvements may not be immediately apparent, the systemic nature of these standards means that strengthening them will have a cascading effect across the entire financial management system. The root causes are widespread, impacting multiple payment streams and creating opportunities for errors to arise. These corrective actions, although not providing immediate, isolated remediation, aim to fortify the foundation of the payment process, ensuring data accuracy, consistency, and interoperability. This foundational strengthening is essential for reducing the frequency of improper payments stemming from various sources. The initial analysis of root causes for short paying invoices is expected by March 2026, with additional measurable CAPs to be created by April 2026.
Furthermore, the proportionality of these long-term corrective actions is carefully considered in light of the Department's broader objectives. While striving to eliminate improper payments, the CAP also recognizes the importance of maintaining operational efficiency and effectiveness. The enhanced data integrity and streamlined processes resulting from these improvements will not only reduce errors but will also contribute to the Department’s ability to minimize late payment interest penalties, preserve government funds, and maintain crucial purchasing power in support of the warfighter. This balanced approach ensures that corrective actions are not only effective in addressing improper payments but also supportive of the DoW's mission-critical priorities. The CAP recognizes that a multi-faceted, strategically proportional approach is required to ensure meaningful and lasting improvements in payment integrity.
The implemented corrective actions are strategically focused on addressing the root causes of improper and unknown payments, particularly within the Commercial Pay - MOCAS program. Specifically, the new requirement, effective May 21st, 2025, for vendors to ensure net disbursements at both the service (if multi-funded) and invoice levels directly tackles the issue of vendors billing credits that do not result in a net debit disbursement at the service level. By returning invoices that do not meet this criterion without processing, the DoW effectively prevents the occurrence of these specific types of improper payments. Similarly, to mitigate improper payments resulting from the DoW's practice of short-paying invoices under certain conditions, the corrective actions target strengthening the implementation and ongoing compliance with critical data standards. Bolstering (OSD) Procure-to-Pay (P2P) Handshakes will improve data exchange accuracy across the P2P lifecycle, while enhanced Procurement Data Standards (PDS) will promote data quality and interoperability. Additionally, strengthening Standard Line of Accounting (SLOA) utilization will facilitate consistent and accurate financial reporting. These combined efforts will reduce the incidence of inaccurate open obligation amounts, thereby minimizing improper underpayments. The MOCAS process is also being reviewed, to allow short pays in special cases, and a possible request for a legislative waiver will be requested if necessary.
These corrective actions are considered adequate to address and prevent the identified improper and unknown payment. However, the full impact of these actions on reducing improper and unknown payments cannot be definitively assessed until the next PIIA review cycle, which examines payments one year in arrears. This time lag necessitates the use of alternative data sources to monitor current performance. To bridge this information gap, management will leverage other available improper payment data, such as ADVANA improper payment prevention data, to track performance in real-time. These insights, combined with the results of future PIIA compliance reviews, will provide a comprehensive understanding of the effectiveness of the implemented corrective actions, allowing for ongoing refinement and optimization to achieve sustained reductions in improper and unknown payments. This ongoing monitoring and adaptive approach would confirm whether the corrective actions are not only adequate but also dynamically responsive to evolving challenges.

Reduction target
0.55 %The Department of War (DoW) affirms that its existing internal controls, human capital, and information systems infrastructure are currently adequate to manage improper and unknown payments to a point where further investment in prevention and recovery efforts would likely exceed the projected cost savings. This determination is based on a comprehensive assessment of our payment processes, incorporating robust data analytics and risk-based strategies. Specifically, the DoW is leveraging its resources to improve data accuracy and consistency concerning contract payments. This includes strengthening data validation processes across systems, implementing rigorous reconciliation procedures, and continuously monitoring compliance with key standards such as P2P Handshakes, the Procurement Data Standards (PDS), and Standard Line of Accounting (SLOA) through established Key Performance Indicators (KPIs). Regular reporting on these KPIs will provide ongoing visibility into the effectiveness of these initiatives and inform any necessary adjustments to maintain an optimal balance between prevention costs and improper payment reduction.
Based on current information available to the Office of the Under Secretary of War (Comptroller) Payment Integrity Team, the Department did not include specific budget submissions explicitly dedicated to payment integrity enhancements in the most recent budget cycle. The Department acknowledges that ongoing system upgrades and maintenance across various financial management systems contribute indirectly to improving payment accuracy and reducing improper payments. The Department's budget strategy emphasizes leveraging existing resources and planned system enhancements to strengthen internal controls and improve data quality related to payments. Future budget submissions will continue to prioritize enhancements that promote payment integrity, incorporating lessons learned and evolving best practices.
Pursuant to the January 20, 2025, Presidential Memorandum entitled “Restoring Accountability for Career Senior Executives” and consistent with the President’s direction U.S. Office of Personnel Management (OPM) established new Senior Executive Service (SES) performance plans that all agencies must adopt beginning with the FY 2026 performance cycle. The “Faithful Administration of the Law and the President’s Policies” critical performance element has the highest weighted rating. Part of implementing these new directives that DoW mandates additional performance requirements specific to Financial Improvement and Audit Remediation (FIAR) standards.
SES members within the Secretary of War with ownership of the financial statement audit priorities will include specific performance requirements aligned to one or more of the annual audit priorities in their Achieving Organizational Goals critical elements. These requirements articulate specific, measurable, attainable, relevant and time-based performance measures that will support each organizational performance goal. As an example “Supports the annual financial statement audit by accelerating the path to an unmodified audit opinion.” SES members with a direct role must comply with the policies and regulations, implement internal control procedures, document transactions, submit auditor-requested materials timely, remediate high risk/priority material weaknesses, develop/update audit roadmaps and drive remediation strategy and plans targeted at achieving an unmodified opinion. They further direct continuous process and internal control improvements, identifies root cause(s) of issues and sustains up-to-date system internal controls. Additionally, SES members are accountable for driving government efficiencies within their organization to streamline proficiencies, quality work and cost-effective use of government resources. SES members with an indirect role must implement timely, effective and measurable corrective actions plans and maintain key supporting documentation to substantiate financial transactions to ensure their workforce is properly trained on their business effectiveness and are held accountable. All of which either directly and/or indirectly equips the DoW with the inherent ability and organizational leadership structure to achieve compliance with the Payment Integrity Information Act.
Furthermore, to provide high-level strategic direction and oversight, the Department of War Payment Integrity Senior Accountable Officials Steering Committee (the Committee) was established in FY 2018. This Committee, institutionalizes a forum of accountability designed to oversee and guide the Department’s actions required by Appendix C of OMB Circular A-123, aiming for full compliance with the PIIA. The Committee is chaired by the Office of the Under Secretary of War (Comptroller)/Deputy Chief Financial Officer and co-chaired by the Defense Finance and Accounting Service, Deputy Director of Operations and has SES representatives from the Military Services and War Agencies. The Committee evaluates the status of improper payment testing, analyzes the root causes of improper payments, oversees payment recovery activities, and drives the resolution of DoW-wide audit findings and recommendations related to improper payments. In addition, the Committee supports related audits, reviews audit recommendations, oversees risk assessments and supervises the identification of root causes and the development/implementation of corrective actions to address areas of non-compliance.
