Protecting Public Trust: Why Segregation of Duties Matters for Government Organizations

Strong internal controls start with separating key financial duties. For New Jersey’s public entities, proper segregation of duties helps prevent fraud, errors, and mismanagement—ensuring taxpayer dollars are protected.

What is Segregation of Duties?

Segregation of duties is an internal control that ensures no single individual has control over all aspects of a critical transaction or process.

The fundamental principle is simple: divide responsibilities among multiple people to create checks and balances. This reduces the risk of:

• Fraud
• Errors
• Misuse of assets or authority

Four Key Functions to Separate

• Authorization – Approving transactions or activities
• Custody – Having physical control of assets such as cash, checks, inventory, and credit cards
• Record-keeping – Recording transactions in the accounting system
• Reconciliation – Reviewing and verifying transactions

Challenges Unique to Public Entities

Small Staff Size – Many smaller municipalities, school districts, state agencies, and special districts have limited personnel, making complete segregation difficult. Hiring additional staff solely for control purposes may not be feasible.

Solutions:

• Use technology and automated controls
• Share resources with other departments or jurisdictions
• Prioritize segregation of duties for highest risk areas
• Crosstrain employees in different departments
• Implement compensating controls (detailed below) as an alternative measure that provides oversight and detection:
  • Management review – Have supervisors or elected officials regularly review financial reports, reconciliations, and transaction details
  • Backup coverage protocol – Ensure employees handling finances have designated, cross-trained backups who assume their duties during any absence
  • Surprise audits – Conduct periodic unannounced cash counts (verifying physical cash matches records) or transaction reviews (checking receipts, payments, and invoices)
  • Detailed documentation – Require comprehensive documentation for all transactions
  • Independent reconciliations – Have someone outside the accounting function – city clerk, mayor, board treasurer, or department director - reconcile accounts monthly
  • Automated system controls – Use software that creates audit trails and requires multiple approvals

Best Practices for Implementation

1. Conduct a risk assessment. Identify processes with the highest risk of fraud or error (usually cash handling, disbursements, and payroll)
2. Document your controls. Create written procedures showing:
   • Who performs each function
   • Required approvals
   • Review and reconciliation responsibilities
3. Provide regular training. Ensure all employees understand:
   • Why segregation of duties matters
   • Their specific responsibilities
   • How to recognize and report concerns
4. Monitor and review periodically.
   • Review segregation of duties annually or when personnel changes occur
   • Update procedures as needed
   • Test controls to ensure they are working effectively
5. Use technology. Modern financial management systems can enforce segregation of duties through:
   • Role-based access controls
   • Required dual authorization for sensitive transactions
   • Automated approval workflows
   • Comprehensive audit trails

Effective internal controls are not about distrust – they are about creating an environment where everyone can work with confidence and transparency.
