DNFSB conducts periodic review of all programs and activities to identify those that may be susceptible to improper payments. In Fiscal Year (FY) 2023, DNFSB performed a risk assessment of outlays exceeding $10 million, based on OMB guidance M-21-19, annual Improper Payment (IP) or Unknown Payment (UP) above $10,000,000 and 1.5% of the program’s total annual outlays are considered to be above the statutory threshold. As a result, the overall DNFSB risk score is low, below the statutory threshold, and is deemed not susceptible to improper payments; comprehensive risk assessments are not required for any DNFSB programs. The next risk assessment is scheduled for FY 2026.
Throughout the year, DNFSB maintains payment integrity by executing internal controls over each payment to mitigate any risk of improper payments and prevent fraud, waste and abuse.
Supplemental Information
The implementation of the Do Not Pay (DNP) initiative is a joint responsibility between DNFSB and the shared service provider, Department of Interior, Interior Business Center (DOI/IBC). When an agency submits requests to add a new supplier in IBC’s Oracle Financial System (OFF), IBC’s Vendor Maintenance Team uses the DNP Online Portal to review the supplier data to ensure that they are not listed as in DNP as ineligible to receive payments from government agencies before being established in OFF. This action ensures that suppliers in Oracle are all valid at the time of creation and is one of the steps to prevent improper payments for customer agencies.
In addition to validating the supplier on the DNP portal, IBC also uses a custom solution to evaluate each vendor record against various approved data sources that house records indicating payments should not be made by a federal agency. DNFSB evaluates the data in the financial system and confirms the suppliers are eligible for payment. All suppliers submitted by DNFSB in Fiscal Year 2025 were eligible to receive payments from the government.

At the conclusion of the Fiscal Year (FY) 2024 Performance Audit of DNFSB’s compliance with the Payment Integrity Information Act, the OIG determined that DNFSB complied with the requirements of the PIIA for FY 2024. The OIG also assessed DNFSB’s compliance with OMB guidance and corresponding reporting instructions and determined that DNFSB met the applicable requirements for PIIA compliance for the one program identified as susceptible to improper payments (IP) or unknown payments (UP). The OIG found DNFSB’s reporting of and performance in reducing and recapturing IPs and UPs to be generally accurate and complete.
