5.1 Construction Accounting & Payroll

Relevance to the NC General Contractor Exam

Construction accounting and payroll compliance are heavily tested concepts on the NC General Contractor licensing exam. The state relies on contractors to operate financially sound businesses while adhering to both federal and North Carolina state labor laws. The exam expects you to differentiate between various accounting methods, such as cash versus accrual, and understand specialized construction revenue recognition models like Percentage of Completion. Additionally, payroll regulations—including the Fair Labor Standards Act (FLSA), proper classification of independent contractors versus employees, and recordkeeping requirements—are frequent targets for questions. A solid grasp of these financial management fundamentals ensures not only exam success but also protection from devastating audits and legal liabilities in practice.

Construction Accounting Methods

Cash vs. Accrual Accounting

In construction, selecting the appropriate accounting method is the foundation of your financial management system. The two primary methods are cash basis and accrual basis accounting.

Cash Basis Accounting: Under this method, income is recorded when cash is actually received, and expenses are recorded when they are actually paid. It is simple and closely tracks the actual cash flow of the business. However, it can be misleading for long-term construction projects. For instance, if you receive a massive mobilization deposit in December but won't incur the associated costs until January, your December income statement will show enormous, artificial profitability, while January will show a massive loss.

Accrual Basis Accounting: This method records income when it is earned (regardless of when the cash is received) and expenses when they are incurred (regardless of when they are paid). Accrual accounting provides a far more accurate picture of a construction company's financial health and profitability on a project-by-project basis. Most construction companies of any significant size, and those seeking surety bonds or bank financing, are required to use accrual accounting.

Revenue Recognition: Completed Contract vs. Percentage of Completion

For long-term construction projects that span across tax years, the IRS and accounting standards (GAAP) dictate how revenue must be recognized.

Completed Contract Method: Revenue and expenses are deferred and not recognized on the income statement until the entire project is substantially complete. While this defers tax liabilities, it creates highly volatile income statements, showing zero revenue from a massive project for months or years, followed by a sudden spike.

Percentage of Completion Method: This is the standard for the construction industry. Revenue is recognized progressively as the project advances. The most common way to determine the percentage is the cost-to-cost method. You calculate the percentage by dividing the costs incurred to date by the total estimated costs of the project. If a project is estimated to cost $100,000 and you have spent $30,000, the project is 30% complete. You then recognize 30% of the total contract value as revenue for that period. This aligns income and expenses, providing a smoothed, accurate view of profitability.

Payroll Regulations and Labor Laws

Payroll is typically a contractor's largest and most heavily regulated expense. Navigating payroll requires strict adherence to federal and state laws.

The Fair Labor Standards Act (FLSA)

The FLSA is the primary federal law governing minimum wage, overtime pay, recordkeeping, and child labor.

• Minimum Wage: Employers must pay covered employees at least the federal minimum wage (or the state minimum wage, whichever is higher). North Carolina generally follows the federal minimum wage.
• Overtime Pay: The FLSA mandates that non-exempt employees receive overtime pay at a rate of not less than one and one-half times (1.5x) their regular rate of pay for all hours worked in excess of 40 hours in a single workweek. You cannot average hours over two weeks. If an employee works 50 hours in week one and 30 hours in week two, they are owed 10 hours of overtime for week one.
• Recordkeeping: Employers must display an official poster outlining FLSA requirements and keep accurate records of employee time and pay for at least three years.

Employee Classification: W-2 vs. 1099

One of the most dangerous pitfalls for a new contractor is the misclassification of workers.

W-2 Employees: These are standard employees. The employer dictates when, where, and how the work is performed. The employer is responsible for withholding income taxes, paying the employer share of FICA (Social Security and Medicare), and providing workers' compensation coverage.

1099 Independent Contractors: These are separate business entities hired to perform a specific task. They control how the work is done, supply their own tools, and have the opportunity for profit or loss. They are responsible for their own self-employment taxes and insurance.

The IRS and state labor boards actively hunt for misclassification. They use a "Common Law Test" focusing on behavioral control, financial control, and the type of relationship. If you tell a worker to be at the job site at 7:00 AM, provide them with a nail gun, pay them hourly, and direct their daily tasks, they are an employee, regardless of whether you make them sign an "independent contractor agreement." The penalties for misclassification include back taxes, severe fines, and potential criminal charges.

I-9 and W-4 Forms

Before an employee begins work, two critical forms must be completed:

• Form W-4: The Employee's Withholding Certificate dictates how much federal income tax to withhold from the employee's paycheck.
• Form I-9: The Employment Eligibility Verification form ensures the worker is legally authorized to work in the United States. Employers must review acceptable documents (like a passport, or a driver's license plus a social security card) within three days of employment. I-9 forms must be retained for either three years after the date of hire or one year after employment is terminated, whichever is later.

Prevailing Wages (Davis-Bacon Act)

If you are working on federally funded or federally assisted public works projects over $2,000, you are subject to the Davis-Bacon Act. This requires contractors to pay their laborers and mechanics no less than the locally prevailing wages and fringe benefits for corresponding work on similar projects in the area. Certified payroll reports must be submitted weekly to prove compliance.
