The Importance of Payroll Compliance
Payroll compliance is one of the most critical operational responsibilities in HR. Errors in payroll can result in employee dissatisfaction, regulatory penalties, lawsuits, and reputational damage. For SHRM exam candidates, understanding the legal framework governing payroll, common compliance pitfalls, and best practices for accurate payroll administration is essential knowledge.
Federal Wage and Hour Laws
Fair Labor Standards Act (FLSA)
The FLSA establishes minimum wage, overtime pay, recordkeeping, and youth employment standards. Key provisions that directly impact payroll include the following.
- Minimum wage: The federal minimum wage sets the floor, but many states and localities have higher rates. Employers must pay the highest applicable rate.
- Overtime: Non-exempt employees must receive overtime pay at one and one-half times their regular rate for hours worked beyond 40 in a workweek. The "regular rate" includes most forms of compensation, not just base hourly pay.
- Exempt vs. non-exempt classification: Employees must meet specific duties tests and salary thresholds to qualify for FLSA overtime exemptions. Misclassification is one of the most common and costly payroll compliance errors.
- Recordkeeping: Employers must maintain accurate records of hours worked, wages paid, and other payroll data for at least three years.
Calculating Overtime
The regular rate of pay, used to calculate overtime, must include base pay, non-discretionary bonuses, shift differentials, and certain other forms of compensation. Discretionary bonuses, gifts, vacation pay, and certain benefit plan contributions are excluded. For employees paid on a piece-rate, salary, or commission basis, special calculations apply to determine the regular rate and resulting overtime premium.
Tax Withholding and Reporting
Federal Income Tax
Employers must withhold federal income tax from employee wages based on the employee's Form W-4 elections. The withholding amount depends on the employee's filing status, claimed dependents, and any additional withholding or adjustments specified on the W-4.
FICA Taxes
Both employers and employees contribute to Social Security (6.2 percent up to the annual wage base) and Medicare (1.45 percent on all wages, plus an additional 0.9 percent employee-only tax on wages exceeding $200,000). Employers must match the standard FICA contributions.
State and Local Taxes
Many states impose income taxes, and some cities and counties levy additional local taxes. With the rise of remote work, employers must navigate increasingly complex multi-state and multi-jurisdiction tax obligations. Determining the correct withholding jurisdiction for remote employees requires careful analysis of each state's sourcing rules.
Year-End Reporting
Employers must furnish W-2 forms to employees and file copies with the Social Security Administration by January 31. Independent contractors receive Form 1099-NEC. Accuracy in year-end reporting is critical, as corrections (W-2c forms) are administratively burdensome and may trigger audits.
Wage Garnishments
Employers are legally obligated to comply with court-ordered wage garnishments, including child support orders, tax levies, creditor garnishments, and student loan garnishments. Each type of garnishment has specific rules regarding maximum withholding amounts and priority. Title III of the Consumer Credit Protection Act limits the total amount that can be garnished from an employee's disposable earnings.
Common Compliance Risks
- Misclassifying employees as independent contractors
- Misclassifying non-exempt employees as exempt from overtime
- Failing to include all required compensation in the regular rate for overtime calculations
- Not paying for all hours worked, including off-the-clock work, travel time, and training time
- Improper deductions that reduce pay below minimum wage
- Late or inaccurate tax deposits and filings
- Failing to comply with state-specific pay frequency, pay stub, and final pay requirements
Best Practices
Maintaining payroll compliance requires ongoing diligence. Regularly audit employee classifications, stay current on federal, state, and local law changes, invest in reliable payroll technology, document payroll policies and procedures, and provide training to payroll staff and managers. Conducting periodic internal audits can identify and correct issues before they become costly problems.
SHRM Exam Focus
Expect questions on FLSA overtime provisions, exempt versus non-exempt classification, the regular rate of pay, tax withholding requirements, and garnishment rules. Scenario-based questions may present payroll compliance situations requiring you to identify violations and recommend corrective actions.
