7 Common Compliance Mistakes Employers Make—and How to Avoid Them

Staying compliant in today’s regulatory landscape is not just about avoiding fines, it is a structural necessity. Government contractors, in particular, face layers of federal, state, and local requirements that evolve frequently and demand precise execution. When organizations fall out of line with these regulations, the consequences can be expensive, disruptive, and damaging to their reputations. Lost contracts, legal disputes, corrective action plans, and strained employee relations are just a few of the very real risks that come with compliance failures.

Yet most compliance issues do not arise from intentional misconduct. They stem from preventable oversights: outdated processes that no longer match current regulations, gaps in policy enforcement, poor documentation, and a lack of internal accountability structures. In many cases, leaders believe they are compliant—that is right up until an audit, investigation, or employee complaint reveals a critical breakdown.

The good news is that most compliance failures can be identified and corrected long before they escalate. Understanding where organizations are most likely to make mistakes is the first step toward building stronger systems, better training, and a healthier compliance culture overall.

Below is a deeper look into seven of the most common compliance mistakes employers make, why they happen, and what you can do to stay ahead of them.

1. Incomplete or Outdated Compliance Policies

Many organizations develop compliance policies once, often during onboarding, a period of growth, or a contract award, and then assume those policies will remain valid for years. In reality, the regulatory landscape shifts continuously. Wage and hour rules, overtime thresholds, and worker classification standards evolve frequently at both the federal and state levels. Employers who fail to update policies in response to these changes risk falling out of compliance long before they realize anything is wrong.

Recent developments in federal labor law highlight how quickly these standards can shift. For example, the U.S. Department of Labor (DOL) issued a major overtime exemption rule in April 2024 that raised salary thresholds for exempt executive, administrative, and professional employees—only for the rule to be vacated nationwide by a federal court on November 15, 2024, reverting employers back to the 2019 thresholds (minimum salary of $684 per week and $107,432 for highly compensated employees). This rapid reversal created widespread confusion and required employers to update policies and employee classifications twice within the same year.

The uncertainty surrounding Executive Orders 14026 and Executive Order 13658 is creating similar challenges. As agencies and contractors continue to receive evolving guidance on which minimum wage requirements apply to new, existing, or modified federal contracts, many organizations are unsure how to structure their pay practices. This ambiguity has led to ongoing questions, compliance concerns, and disruptions in payroll administration. Contractors are particularly struggling with issues such as determining applicability during option years, reconciling conflicting wage floors, and assessing whether retroactive price adjustments are necessary. As with the overtime rule reversal, the lack of stability in federal labor standards is forcing employers to repeatedly revise policies and compensation structures with little advance notice.

Without scheduled policy reviews and clear ownership of compliance monitoring, many organizations unknowingly operate under outdated rules, exposing themselves to investigations, employee claims, or disqualification from government contracting opportunities.

Why This Mistake Happens:

• Policies are written during onboarding, expansion, or contract bidding phases and never revisited.

• No designated owner for tracking and implementing compliance updates.

• Leadership assumes “If nothing seems wrong, we must be compliant,” overlooking risks such as misclassification or insufficient documentation.

• Rapid regulatory changes create confusion, especially when court decisions temporarily block or reverse new rules.

   

How to Fix it:

• Conduct formal policy reviews at least annually.

• Subscribe to regulatory updates from agencies like the Department of Labor (DOL) and Internal Revenue Service (IRS).
• Assign a compliance lead or outsource policy management to a third-party specialist such as The Onsi Group.
• Document every policy revision and communicate changes to employees.
  
  

2. Poor Documentation and Recordkeeping

In federal contracting, documentation is often the first thing an auditor or investigator requests—whether it is a Department of Labor wage and hour investigation, a Defense Contract Audit Agency (DCAA) accounting system or incurred-cost audit, or an IRS employment-tax review. Even if your practices were substantively correct, missing, inconsistent, or incomplete records can create findings, trigger withholdings, or delay invoice payments. Under the FLSA, employers must maintain accurate timekeeping and payroll records; failure to do so can result in back wages, penalties, and litigation, as without them, an employer would be unable to demonstrate compliance. For federal contractors, weak time/labor records are a common reason for DCAA audit failures.

Common Documentation Gaps Include:

• Missing timecards or inconsistent timekeeping practices.
• Incomplete or incorrectly retained I-9 forms.
• Insufficient payroll tax back-ups.
• Missing training records or proof of policy enforcement.
• Lack of written job descriptions and labor-category mapping.

How to Fix it:

• Standardize documentation procedures across all departments.
• Use digital systems to centralize and automate recordkeeping.
• Train managers on what must be documented and why.
• Conduct periodic internal audits to identify gaps.
• Tie documentation to cash flow on active awards.
• Adhere to record retention schedules
  
  

In the federal contracting environment, employee training is not optional—it is a core compliance control that directly affects contract eligibility, audit outcomes, and wage and hour risk. Even the strongest written policies fail if employees and supervisors do not understand how to apply them in daily work. This is especially true for government contractors, whose obligations expand beyond standard employer requirements into FLSA timekeeping accuracy, Service Contract and Davis Bacon Act employee classification and compensation requirements, DCAA labor‑charging rules, IRS payroll record expectations, and heightened vulnerability to Wage and Hour Division (WHD) investigations.

Training gaps often surface first during a DCAA floor check, WHD wage and hour audit, or IRS employment‑tax review, where auditors interview employees and test whether practices align with written policies. Inconsistent or outdated training can therefore create compliance findings even if the underlying processes were intended to be correct.

Why This Mistake Happens:

• Training is treated as a one-time onboarding task.
• Managers assume employees “already know” the rules.
• Training materials become outdated as regulations change.
• Employees are unaware they must record all hours daily and that backdating or estimating hours violates DCAA rules.
• Employees and managers are not trained on what is “compensable time” under the FLSA (e.g., travel time, waiting time).
• Managers not trained to identify risks that prompt DOL investigations, including misclassification and incorrect overtime calculations.

How to Fix it:

• Provide annual refresher training for all employees, including FLSA basics, DCAA timekeeping rules, compensable time standards, and contract-specific requirements, ideally delivered through a structured platform such as Onsi University.
• Train managers and supervisors separately so that they accurately understand what they must monitor.
• Document all training completion.
• Update training materials whenever policies or laws change, leveraging Onsi Group’s ongoing compliance updates to ensure accuracy and consistency.
  
  

Inconsistent application of wage‑and‑hour, timekeeping, safety, or disciplinary policies can produce WHD (DOL) investigations and DCAA audit findings, even when written policies look compliant. WHD investigators are authorized under the FLSA to review your records, inspect premises, and interview employees; inconsistent practices make those interviews risky and can lead to back‑wage assessments and, on covered contracts, withholding of funds pending resolution. Meanwhile, DCAA evaluates whether your labor‑charging controls (daily employee time entry, supervisor approvals, change audit trails, total‑time accounting) are consistently followed; inconsistency here is a frequent cause of questioned costs and accounting‑system deficiencies.

Examples of Inconsistent Enforcement:

• Disciplining one employee for tardiness but ignoring it for another.
• Allowing certain teams to skip required timekeeping or compliance training.
• Enforcing safety rules only after an incident occurs.
• Applying different standards to remote vs. on-site employees

How to Fix it:

• Train managers on consistent application of timekeeping, overtime, break, and disciplinary rules.
• Use standardized disciplinary procedures.
• Document all corrective actions.
• Conduct periodic reviews to identify patterns of inconsistency.
  
  

Federal rules (FLSA) set the floor; states and cities often go further on minimum wage, paid sick/family leave, travel/meal period rules, and other wage‑and‑hour standards. Contractors with remote or multi‑state teams must comply with the more protective standard for the employee, and state agencies routinely enforce in parallel to WHD. The Department of Labor maintains a current directory of state labor offices and local WHD offices which is the right starting point for jurisdiction‑specific guidance and enforcement contacts.

Why This Mistake Happens:

• Employers assume federal rules override state rules.
• Multi-state employers struggle to track variations.
• Rapidly changing state laws (e.g., paid leave, wage thresholds) create confusion.

How to fix it:

• Maintain a compliance matrix for every state where you operate.
• Review state laws before hiring remote employees in new locations.
• Subscribe to state agency newsletters and alerts.
• Consult legal counsel when expanding into new jurisdictions.
  
  

6. Not Conducting Regular Internal Audits

Compliance is dynamic. Without periodic self‑checks, small issues (e.g., missed time entries, misallocated labor, outdated pay practices) become systemic risks that are expensive to remediate and can delay billings or trigger withholdings on federal contracts. WHD explicitly encourages employer self‑audits through its Payroll Audit Independent Determination (PAID) program, which was relaunched/expanded in 2025 to include certain FMLA matters, allowing proactive correction of FLSA/FMLA issues with agency cooperation and reduced litigation exposure. DCAA CAM also expects effective internal controls and monitoring—auditors will ask how you test that policies are followed and controls are working.

What Internal and External Audits Should Cover:

• Payroll accuracy and hours worked
• Timekeeping practices and labor charging
• Worker classification
• I-9 compliance
• Safety procedures and training records
• Policy enforcement consistency
• Training completion records

External audits—such as those performed by Onsi Group—provide an independent, contractor-focused review of these areas, helping identify gaps internal teams may miss and strengthen overall compliance readiness.

How to Fix it:

• Schedule quarterly or annual audits depending on risk level and document findings and corrective actions.
• Use third-party auditors, like the Onsi Group, for unbiased assessments.
• Re-train managers on areas where issues are found.
  
  

7. Misclassifying Employees 

Misclassification fuels back‑wage/overtime liability, penalties, potential withholding on covered contracts, and reputational damage. WHD’s current materials emphasize the “economic realities” approach under the FLSA to distinguish employees from independent contractors, and DOL’s 2024 final rule (effective March 11, 2024) set a multi‑factor analysis—while later enforcement guidance in 2025 (FAB 2025‑1) signaled WHD’s reliance on the longstanding economic reality framework for enforcement. Contractors should build classification decisions that stand up under either articulation.

Consequences of Misclassification:

• Back wages and overtime
• Penalties and fines
• Tax liabilities
• Class-action lawsuits
• Reputational damage

How to Fix it:

• Review job duties (not job titles) when determining exemption status.
• Reassess contractor relationships annually and when scopes change.
• Train managers and recruiters on FLSA classification criteria, using Onsi’s FLSA trainings for consistency.
• Use written contracts that accurately reflect the working relationship.
• Consult legal or compliance experts when in doubt.
