1099 vs. W-2 workers in construction: What’s the difference?

Ask a finance leader whether their company’s team is made up of W-2 employees or 1099 independent contractors, and the answer is probably “both.” Most construction companies have a core crew of W-2 direct hires backed by a rotating bench of 1099 subs. As a result, finance leaders need to understand two things: the fully burdened labor cost of 1099 vs. W-2 workers and how to keep the division clean and separate.

Worker classification is based on specific legal and operational criteria, not contractor preferences. Getting it wrong can have tangible consequences for a contractor’s bottom line, from back taxes to workers’ comp audits to prevailing wage violation fees.

This guide outlines the main differences between 1099 and W-2 workers to help contractors and finance leaders manage their workforces confidently. It clarifies how the classification tests work in practice and what incorrect categorization actually costs companies.

What is a W-2 employee?

W-2 employees are workers hired directly by an employer and paid through payroll. Employers withhold state and federal income taxes, Social Security, and Medicare contributions on the employee’s behalf. The employer reports income and withheld taxes on Form W-2 each tax year.

W-2 employees work under the direct guidance and supervision of their employers. Companies define the workers’ hours, tasks, and pay. Employees may also receive employer-sponsored training and equipment, benefits, and workers’ compensation coverage.

In construction, many W-2 roles fall into one of the following categories:

• Supervisory and planning roles: Field supervisors and foremen run crews and jobsites, while estimators and project managers build bids and manage budgets. In all cases, they work using company systems and schedules, and it’s this employer direction-and-control that puts them in the W-2 sphere.
• Field crew and tradespeople: Journeymen, general laborers, helpers, and equipment operators fall squarely into the W-2 category when they’re hired directly onto the company payroll and work under the superintendent’s direction using company equipment. This is typically the largest group in a contractor’s W-2 roster, which also makes it the likeliest place for misclassification mistakes to show up.
• Apprentices: While they’re tracked separately from journeymen, registered apprentices come with all the same obligations as other W-2 employees. Employers also manage some added hurdles like prevailing wage apprentice rates, apprentice-to-journeyman ratio requirements for public works jobs, and certified payroll implications.
• Seasonal and temporary field workers: Just because a worker is “temporary” doesn’t automatically mean they’re not a W-2 employee. The same control test applies whether someone stays for a few jobs or a few years.

What is a 1099 employee?

A 1099 worker is an independent contractor or self-employed person. Unlike W-2 employees, 1099 workers control the way they work, pay their own taxes, and usually don’t get employer-sponsored benefits. 1099 workers receive the 1099-NEC tax form each tax year.

Common types of 1099 workers in construction include:

• Specialty subcontractors: Contractors often need a specific type of work done, like roofing, HVAC, or demolition, but not frequently enough to have a dedicated team to handle the task. That’s when they bring in outside subcontractors with their own crews, equipment, insurance, and licenses. If a sub is unincorporated, payments reaching or exceeding $2,000 need to be reported on Form 1099-NEC. Payments to subs operating as their own company, often as an S Corp or LLC, are often exempt from 1099 reporting.
• Independent equipment operators: Equipment operators who bring in their own machinery and set their own rates are typically 1099 independent contractors.
• Independent individual tradespeople: A solo tradesperson who controls their own methods, tools, and schedule can work on a 1099, but this is also the category subject to the most scrutiny because it’s easy for the relationship to drift toward employer control.
• Licensed professionals engaged per project: Engineers, architects, and safety consultants who run their own professional practice on a per-project basis and control their own work are usually 1099 independent contractors.

Differences between 1099 and W-2 workers

These are the primary differences between 1099 and W-2 workers companies need to know.

Work control and supervision

Level of control is one of the main legal tests the IRS uses to classify workers. W-2 employees generally work under their employer’s direction and supervision, while 1099 workers have more control over aspects like scheduling, methods, and equipment.

Benefits and workers’ compensation coverage

W-2 employees may get health insurance, retirement contributions, paid leave, and workers’ comp coverage, though the latter is often a statutory requirement. 1099 contractors generally don’t receive employer-sponsored benefits. 

Fully burdened labor costs

The true cost of employing a W-2 worker is often 1.25–1.4 times their base wage after accounting for:

• Federal Insurance Contributions Act: 7.65% of annual gross wages
• Federal Unemployment Tax Act: 6% of the first $7,000 employees make, unless contractors take the 5.4% FUTA tax credit; in that case, FUTA is 0.6%
• State Unemployment Tax Act: Percentages vary by state, ranging from 0–15%
• Workers’ comp: Varies depending on trade and state; average is about 1% of total compensation, but costs can reach as high as $40 per $100 of payroll for high-risk trades like roofing
• Benefits: Around 30% of total compensation, according to the Bureau of Labor Statistics; costs change based on location, benefits package contents, and fringe benefit requirements

A 1099 worker’s bid usually has everything priced in, which means contractors should be comparing the fully burdened W-2 cost to the all-in contractor rate, not the W-2 wage to the 1099 worker’s hourly. Keep in mind that while hiring a 1099 worker can cut down on some overhead, overall cost still varies by contractor rates, insurance obligations, and project structure.

Year-end tax reporting and deductions

For W-2 workers, employers withhold income taxes, Social Security, and Medicare contributions on the employee’s behalf. W-2 employees receive Form W-2 from their employers explaining these withholdings. 

1099 independent contractors earn a gross paycheck and cover their own taxes, including self-employment taxes. They can also deduct qualifying business expenses.

Certified payroll and prevailing wage reporting

Federal Davis-Bacon laws state that anyone working on a qualifying project, whether they’re a W-2 employee or not, must earn prevailing wages and be included in certified payroll reports. Independent contractor status may need to be noted so funding agencies know why employers didn’t withhold FICA taxes. Note that for public works jobs, if subcontractors don’t follow the reporting and pay regulations, the primary contractor is on the hook for these violations.

Should my construction workforce be 1099 or W-2 employees?

Contractors don’t get to choose how to classify a worker. Their job is to determine which category a worker falls into by law, which typically comes down to a series of tests.

IRS common law classification test

This test identifies the “degree of control and independence” a worker has over what they do, based on three questions:

• Behavioral: Does the company have the right to control how the worker does their job?
• Financial: Does the employer determine the way workers are paid and reimbursed? Are the business aspects of the work controlled by the entity that pays for it?
• Type of relationship: Are there written contracts? Does the employer provide benefits? Is the relationship ongoing and the work performed a key aspect of the business?

DOL economic reality test

This test for classifying a worker as an employee or an independent contractor under the Fair Labor Standards Act (FLSA) expands the list of determination factors to:

• Opportunity for profit or loss depending on managerial skill
• Investments by the worker and the employer
• Permanence of the work relationship
• Nature and degree of control
• Whether the work performed is integral to the employer’s business
• Skill and initiative

Together, these elements point to whether a worker is economically dependent on the company (and therefore an employee) or independent. Regulatory interpretations are subject to change and can vary by administration.

State ABC tests and construction-specific rules

States like California have their own stricter “ABC tests” that automatically count a worker as an employee unless they satisfy certain criteria, such as performing work the hiring entity doesn’t typically perform. Some states also have construction-specific classification rules, carve-outs, or exemptions to be aware of before finalizing a classification.

Risks of misclassifying construction workers

Misclassifying employees exposes construction companies to a variety of risks.

Back taxes

Contractors are on the hook for unpaid payroll taxes, withholding obligations, and unemployment taxes.

IRS, DOL, and state agency penalties

Classification mistakes can hit contractors with penalties, interest charges, and audits from government agencies. Intentional misclassification amplifies the risk.

Workers’ compensation audit exposure

A workers’ comp audit might take place to assess retroactive premiums the contractor is responsible for.

Certified payroll and prevailing wage violations

Misclassification can be extra damaging on prevailing wage jobs, where underpayment issues, certified payroll inaccuracies, or public works compliance violations stack on top of any federal or state misclassification penalties.

Lawsuits

Disgruntled workers may take contractors to court over unpaid overtime, missed benefits, lacking workers’ comp coverage, or labor law violations.

Reputational and operational damage

Even without a court case, misclassification can damage a contractor’s relationships with workers, project owners, and labor partners. This is especially true when misclassification leads to investigations, enforcement actions, or payroll disputes. Contractors may lose out on future work as a result.

Choosing between W-2 and 1099 for each construction role

Despite the benefits of 1099 vs. W-2 workers (and vice versa), employers are ultimately forced to choose the classification that accords with the law. That means the decision depends not on cost considerations, project length, or worker preference, but on the level of control and permanence that defines the working relationship.

Most contractors use a hybrid W-2/1099 system that often looks something like this:

• Core W-2 crew: Some roles are needed for every job, such as foremen, superintendents, general laborers, and directly scheduled and supervised trades.
• Specialty 1099 scopes: Sometimes contractors need specialty work done, so they bring in licensed roofing, HVAC, and electrical subs who run their own business (insurance included) and control their own work.

Manage 1099 and W-2 workers in one centralized place

When payroll and workforce management are cut off from certified payroll reporting and job costing, compliance risk and job costing errors tend to find their way in. Finance leaders juggling the needs and compliance requirements of hybrid workforces need connected systems so payroll, time tracking, and certified payroll reporting pull from the same records.

Miter is a construction-specific HRIS and payroll platform that stores all this data in one place. Contractors onboard W-2 employees and 1099 contractors in one system, run payroll for both, and issue the matching W-2s and 1099s at year end. Time tracking and certified payroll reports pull from the same records, so classification stays consistent from timesheet to tax form.

Miter simplifies payroll and compliance no matter what the workforce looks like.
