Investigation of Waste at Mercer County Finance Department
Table of Contents
An Office of the State Comptroller (OSC) investigation has found that Mercer County incurred and paid nearly $4.5 million in penalties and interest for delinquent tax filings and payments between 2018 and 2021, resulting in waste that was paid by Mercer County taxpayers. During that time period, the Mercer County Finance Department (MCFD) consistently made insufficient and untimely payroll tax payments to the Internal Revenue Service (IRS) and the New Jersey Division of Taxation (Division of Taxation). For each delinquent filing, Mercer County was assessed penalties and interest that could have been avoided.
In the course of the investigation, OSC also discovered that the Chief Financial Officer (CFO) for the County lacked the statutorily required certificate to serve as CFO. OSC also found that MCFD’s operations contravene best practices for the management and operation of a public entity’s finance department, creating additional risk for fraud, waste, and abuse.
In order to avoid penalties and interest and to ensure that taxpayer funds are protected, OSC makes six recommendations to Mercer County at the conclusion of this report.
A. Mercer County Government
Mercer County operates under a county executive form of government with a Board of Commissioners serving as the County’s legislative body and a County Executive administering county operations.1 The Board consists of seven members elected to three-year staggered terms.2 The Board is responsible for (1) adopting the County’s Administrative Code; (2) passing ordinances and resolutions; (3) reviewing, modifying, and adopting all operating and capital budgets; (4) evaluating and studying the County’s annual budget before final approval; and (5) entering into contracts with municipalities in the county.3
The County Executive is elected to a four-year term of office.4 The Office of the County Executive is responsible for oversight of the County’s various departments. Department heads are appointed by the County Executive, with advice and consent from the Board.5 Within the Office of the County Executive, the County Administrator manages the day-to-day operations of the County.
B. County Chief Financial Officer
New Jersey law requires every county to appoint a CFO who is responsible for the proper financial administration of the county.6 The CFO’s statutory duties include, among other things, (1) acting as custodian of all public funds; (2) developing a system of internal controls to protect assets and ensure proper accounting compliance; and (3) complying with IRS regulations regarding employee payroll and vendor payments.7 County CFOs are appointed for three-year terms and must hold a county finance officer certificate issued by the Division of Local Government Services (LGS), a division within the state Department of Community Affairs.8 Requirements to obtain a certificate include certain higher education requirements, experience as a county finance officer, and satisfactory completion of various training courses.9
The Mercer County CFO is appointed by the County Executive and serves as Treasurer and Director of the Finance Department. In addition to the CFO’s statutory duties, the Mercer County CFO is responsible for providing accounting records and preparing the county’s annual financial statements, preparing the annual budget, and providing for long-term capital financing for county entities. 10
C. Federal and State Payroll Taxes
Employers, including governmental entities, must pay federal and state payroll taxes based on a percentage of an employee’s compensation. The employer is responsible for withholding the correct amount of payroll taxes from each employee’s paycheck and remitting the funds to federal and state taxing authorities, along with the employer’s share of the payroll taxes.11 These federal and state tax deposits must be remitted to the taxing authorities in a timely manner after each payroll cycle. The due date for the payroll tax deposits is based on the employer’s size and the frequency of payroll cycles.12 Employers are required to prepare and file quarterly payroll tax returns with the federal and state taxing authorities. The returns are due on the last day of the month following the end of the quarter. The return calculates quarterly payroll taxes, reconciles payroll taxes due to amounts previously paid, and identifies additional taxes that must be paid and refunds owed to employers.13
D. Payroll Tax Penalties
Employers that do not timely file payroll tax returns are subject to a penalty.14 For federal payroll taxes, the penalty is set at five percent of the unpaid taxes for each month or part of a month that a tax return is late, and is capped at 25 percent of the employer’s unpaid taxes. If the employer’s return is more than 60 days late, the minimum failure to file penalty is $435 or 100 percent of the tax required to be shown on the return, whichever is less. A failure to file penalty is capped after five months.
Employers that do not pay the tax reported on their return by the due date are subject to a separate penalty, known as a “Failure to Pay Penalty.”15 This penalty continues until the delinquent tax is paid, up to a maximum of 25 percent of the unpaid tax. In addition to the failure to pay penalty, the IRS also charges interest on any unpaid payroll tax until the balance is paid in full.16
The Division of Taxation also charges penalties and interest for the late filing and payment of state payroll tax returns. Like the IRS, the Division of Taxation imposes a late filing penalty of five percent of the unpaid tax for each month or part of a month a payroll tax return is late, capped at 25 percent of the total unpaid tax.17 The Division of Taxation also charges a five percent late payment penalty for the underpayment of taxes in addition to interest on the unpaid balance due.18
OSC’s investigation was initiated upon receipt of a confidential complaint in 2021. OSC is authorized to conduct investigations concerning alleged fraud, waste, abuse, or mismanagement of State funds, designed to provide increased accountability, integrity, and oversight of county and municipal governments. To conduct its investigation, OSC obtained and examined numerous documents, including IRS account transcripts for quarterly payroll tax returns for the period of 2018 to 2021.
OSC conducted interviews with multiple current and former employees of MCFD, as well as the Mercer County Administrator. OSC attempted to interview David Miller, the Mercer County CFO during the period under review, about the operations of MCFD and the issues identified in this report. Mr. Miller through his attorney represented to OSC that if interviewed he intended to exercise his right against self-incrimination under the Fifth Amendment to the United States Constitution.
OSC sent discussion drafts of this Report to Mercer County and Mr. Miller to provide them with an opportunity to comment on the facts and issues identified during this review. In preparing this Report, OSC considered the responses received and incorporated them where appropriate.
A. From 2018 to 2021, Mercer County Incurred Nearly $4.5 Million in Penalties and Interest for Late Payroll Tax Filings and Payments.
1. Penalties and Fees Related to Federal Taxes
From October 2018 through the end of 2020, the County incurred over $900,000 in penalties due to its failure to file timely federal payroll tax returns, ultimately paying nearly $830,000 after an IRS abatement of $73,000.19 In 2018, the County filed its fourth quarter payroll tax return nine months late. The County failed to file even one timely payroll tax return for 2020. On average, the 2020 quarterly returns were filed five months late, with the third quarter return filed over seven months late and the fourth quarter return filed almost nine months late. This resulted in the IRS assessing late filing penalties of almost $700,000, with the County paying $600,000 after receiving an IRS abatement. IRS Account Transcripts dated May 18, 2022 indicated that the County as of that date had not filed the 2021 fourth quarter payroll tax return and, as a result, may be subject to additional penalties and interest.
Mercer County also incurred “Failure to Pay” penalties for 13 consecutive quarters from July 2018 through September 2021. This resulted in Mercer County paying over $2.7 million in penalties after the IRS abated almost $1 million in penalties for late payments for the same period.
From July 2018 through March 2021, the County also incurred over $363,000 in interest charges and paid over $334,000 after an IRS abatement. During that time, there was only one quarter in which the County was not charged interest due to late payments. For that one quarter (the third quarter of 2019), the County overpaid its tax liability by more than $3 million. The IRS automatically applied part of that overpayment to the County’s prior delinquent taxes as far back as 2015 and refunded the remaining amount.
2. Penalties and Fees Related to New Jersey State Taxes
During the course of this investigation, OSC requested information about penalties and interest Mercer County paid to the Division of Taxation in excess of its payroll tax liabilities, but the County did not provide any responsive records. As a result, OSC obtained from the Division of Taxation directly a summary of penalties and interest incurred and paid by the County since 2009. OSC found that between 2018 and 2021, the County paid $599,889 in penalties and interest.
3. MCFD Did Not Maintain Any Written Policies and Procedures Governing the Filing and Payment of Payroll Taxes
OSC requested MCFD’s written policies and procedures governing the filing and payment of payroll taxes and was informed that MCFD did not maintain any. As a result, OSC obtained information about MCFD’s payroll tax processes through interviews with MCFD employees.
As part of the payroll process, MCFD’s accounting software generates paper checks for MCFD to pay its payroll taxes. However, according to MCFD employees, Mr. Miller regularly instructed the payroll clerk to void these checks and, instead, submit the federal tax deposit through the IRS’s automated phone system. MCFD employees also reported that Mr. Miller would take the voided state payroll tax checks and wire the payments to the taxing authority himself.
MCFD employees could not identify a reason why the payroll tax deposits and returns were not timely filed. Rather, one witness reported that Mr. Miller described the penalties and interest as simply “the cost of doing business.” Further, despite several requests, the County did not provide a complete list of all its bank accounts, the names of the individuals who had access to the accounts, or documentation of how the penalties and interest were paid.
B. The County CFO Did Not Possess the Certificate Necessary to Serve in That Role.
By statute, an individual must hold a county finance officer certificate issued by LGS to serve as a County CFO.20 OSC’s investigation revealed that Mr. Miller did not hold, or even apply for, a county finance officer certificate during his entire tenure as Mercer County CFO.21 As a result, Mercer County was without a properly credentialed CFO for over a decade.
C. MCFD Failed to Follow Best Practices in the Operation of the Department and Was Inadequately Staffed.
Best practices for the management and operation of a public entity’s finance department include, among other things, reliance on a formal organizational chart; the use of written policies and procedures for each task performed by the department (e.g., the filing and payment of payroll taxes); the segregation of department duties; and thorough documentation of the responsibilities of each position within the department.22 Executive level employees should actively oversee the implementation of internal controls developed to ensure integrity in the management of public funds, monitor the performance of those controls, and work with a committee to oversee the department’s operations.23
OSC’s investigation found that the County and MCFD failed to follow these best practices, creating a risk for fraud, waste, and abuse. MCFD does not have an organizational chart clearly defining the department’s reporting structure, identifying the positions available within the department, and listing the current staff members. MCFD also does not have written policies and procedures establishing internal controls and the segregation of duties that provide checks and balances on employees involved in approving expenditures of public funds.
The County Administrator — the Mercer County representative responsible for overseeing MCFD — told OSC that she was unaware of any written policies or procedures guiding the operation of MCFD. When asked specifically about policies governing the segregation of department duties, the County Administrator stated that an employee’s formal job title and the duties assigned to that title ensure department duties are effectively segregated. When questioned further, however, she acknowledged that the formal job titles and duties do not necessarily correspond to the work MCFD employees perform or ensure the segregation of duties. Further, although the County Administrator stated that she held monthly meetings with all department heads, she provided Mr. Miller with substantial discretion with regard to his administration and operation of MCFD with no direct oversight of the department’s day-to-day operations.
In its response to a draft of this report, the County asserted that Mr. Miller was responsible for the daily operations of the Finance Department and was expected to bring issues of concern to the attention of the County Administrator. Any discretion provided to department leaders over the daily operations of their respective departments, however, does not relieve county management of the duty to proactively ensure that county departments are operating efficiently, preventing waste, and adhering to best practices.
Additionally, annual independent audits of the County repeatedly noted issues regarding a lack of adequate staffing within MCFD. The auditor noted that inadequate staffing levels resulted in untimely reconciliations and untimely compliance with audit requirements. At least twice, the external auditor discussed with the current and former County Administrators a need for additional staff in the finance department to ensure the County remained current with its audit requirements. The auditor stated that the annual audits were consistently delayed because the County did not provide the necessary documentation in a timely manner. In 2019, the external auditor recommended that the County hire a Deputy CFO.
In its response, the County stated the County Administrator was made aware in 2019 that the independent auditor recommended that MCFD hire additional staff. The County also claimed that it took steps to hire one additional staff member, a Deputy CFO, at that time. The County, however, did not actually hire a Deputy CFO until May 2022, almost three years after receiving the recommendation from the independent auditor. The County reported that the delay in hiring a Deputy CFO from 2019 to 2022 was due to the COVID-19 pandemic.
Based upon the facts uncovered in its investigation, OSC makes the following six recommendations intended to promote more efficient government. In its response to OSC’s draft report, the County agreed to implement OSC’s recommendations, and indicated the County has already formed a Finance Committee to oversee the operations of MCFD.
- Filing and Payment of Federal and State Taxes. The County should ensure that it files all taxes, including payroll taxes, in a timely manner and pays the amounts due within the timeframe required by taxing authorities. The County should also identify all outstanding tax penalties and, when applicable, promptly request abatements for those penalties.
- County Employee Credentials and Licenses. The County should ensure that all employees who require a license, certificate, or other form of credential to perform their job duties possess those credentials and maintain them in good standing. The County should also adopt written policies and procedures directing the County Office of Personnel to annually verify that employees possess and maintain in good standing the credentials necessary to perform their job duties.
- Development of an Organizational Chart for the Finance Department. The County should adopt an organizational chart that clearly establishes the department’s reporting structure and includes a current list of positions, employees, and supervisors.
- Development of an Accounting Procedures Manual. The County should develop an accounting procedures manual. The manual should establish a clear segregation of duties and a system of checks and balances to ensure financial systems are properly managed and that issues identified in this report, such as the untimely filing of tax returns and paying payroll taxes, are avoided. A comprehensive accounting manual will also aid in the training of new employees.
- Establish a Committee to Oversee MCFD Operations. The County should establish a committee to oversee MCFD, including its financial reporting practices, internal department controls, and compliance with laws and regulations affecting the department.
- Increased Oversight of the CFO. Prudent financial management requires periodic review of the Mercer County Finance Department by an individual outside of MCFD and within the Office of the County Executive and the Board of Commissioners. The County CFO should be required to submit operational reports on a monthly basis that include expenditures and revenues. The monthly report should include a list of all tax liabilities and payments for that month and disclose penalties and interest.

 Taxpayers can request relief from penalties. For a failure to file or pay penalty, taxpayers can request that the IRS “abate” the penalties. Abatement is simply removing the penalties after they are assessed to the taxpayer.
