Preventing Another D.C. Tax Scheme

We do not know the complete
story of D.C. tax scheme. However, it is difficult to understand how such a
massive tax fraud could occur without being noticed or captured by the
leadership or the available information systems.
The District has several major
enterprise systems for financial management, payroll and pension
administration, and tax administration.
Several high-ranking officials at
the Office of Tax and Revenue have been asked to resign. According to
Channel 4, D.C. Chief Financial Officer (CFO) believes that they should have
discovered the irregularities earlier.
Apparently, the scheme started in
2004, or earlier, and involved real estate tax refunds. The Washington Post
(Nov. 8, 2007) reported that this summer a bank employee refused to cash a
$410,000 refund check triggering a federal investigation.
According to the Washington Post,
D.C. CFO championed multimillion-dollar investments in audits and on a
computer tracking system, specifically for the Office of Tax and Revenue to
spot financial irregularities. So, why did the audits and the computer
tracking system failed?
Software tracking systems, such as
enterprise resource planning (ERP) systems are widely used for measuring
individual and organizational performance, preventing internal theft,
enforcing laws and workplace rules, and integrating production, inventory
control, scheduling, purchasing, and cost accounting.
An ERP is an integrated system with
modules addressing each process in the organization. However, many
organizations implement information systems in a fragmented fashion; meaning
that they implement various stand-alone systems in different departments
that do not seamlessly interact with one another. D.C. government appears to
have implemented multiple stand-alone systems. A 1999 statement, from D.C.
former CFO Valerie Holt, on Year 2000: The Readiness of SOAR and other Information
Systems, lists 8 systems.
Often, fragmented systems are
territorial and outside of the purview of the organization hierarchy. Thus,
the group managing the system can allow it to degenerate. Some stand-alone
systems are not even reconciled on a monthly basis.
In practice, however, information
systems support best practices, such as Business Process Redesign (BPR)
across several core business functions. BPR is a pre-planning stage for ERP,
a key “mapping” concept for aligning business strategies with information
technology. So, the organization codifies “best practices” within the
software. Therefore, if the Office of tax and Revenue information system
issues large real estate tax refunds, such as the $410,000 refund check that
the bank teller refused to cash, there should be a procedural check to
validate the refund.
The DC Office of Tax and Revenue
should revisit existing procedures and managerial roles to ensure that a
similar situation will not occur. Moreover, it should evaluate the
effectiveness of its informational systems, as well as auditing procedures.
