Labor is one of the top three costs in shed manufacturing and in most construction trades. The way that labor is engaged, as employees or as independent contractors, shapes payroll taxes, insurance, liability, and the legal exposure of the whole operation, so the classification decision deserves the same review as a contract or a permit.
The rules that govern the decision come from two directions. The Internal Revenue Service applies its right-to-control test for tax purposes, and the Department of Labor applies the economic reality test under the Fair Labor Standards Act for wage and hour purposes. State agencies add their own versions, and a worker can be classified differently under different laws.
Getting it wrong is expensive. Before the first worker is hired under either model, review the independent contractor classification rules and the legal resources every builder should know, then document the arrangement the same way you document the build.
The Right-to-Control Test: How the IRS Decides
The IRS test is commonly called the right-to-control test because each factor asks the same question: who controls how the work is done? The regulations and common-law practice treat the worker as an independent contractor when control of the services, the products, and the results of the engagement rests with the worker. When the company exerts more control, the worker is more likely an employee.
The Twenty Control Factors
- Level of instruction
- Amount of training
- Degree of business integration
- Extent of personal services
- Control of assistants
- Continuity of relationship
- Schedule flexibility
- Demands for full-time work
- Need for on-site services
- Sequence of work
- Requirements of reports
- Method of payment
- Payment of business or travel expenses
- Provision of tools and materials
- Investment in facilities
- Realization of profit or loss
- Work for multiple companies
- Availability to the public
- Control over discharge
- Right of termination
Two factors concern the end of the relationship. Control over discharge and right of termination weigh heavily because a contractor who can be fired at will looks like an employee, and firms that document how they manage employee terminations protect themselves when a departure turns hostile.
Behavioral Control in Practice
Behavioral control shows up in the daily routine. A crew that must follow the builder’s schedule, use the builder’s methods, attend the builder’s training, and work under the builder’s supervision is being controlled like employees regardless of the label on the contract. The more instructions the company gives, the more the factors point toward employment.
The Economic Reality Test Under the FLSA
The Fair Labor Standards Act does not apply to independent contractors, which is why the Department of Labor uses a separate test to decide who counts as an employee for minimum wage and overtime purposes. The economic reality test looks at the whole relationship rather than a checklist, focusing on whether the worker is economically dependent on the employer.
- The extent of control by the employer over how the work is done
- The worker’s opportunity for profit or loss based on managerial skill
- The worker’s investment in equipment and facilities
- The permanence of the working relationship
- Whether the services are integral to the employer’s business
- The worker’s skill, initiative, and business judgment
Builders routinely compare the two models for each trade. Weighing a subcontractor versus independent contractor arrangement means looking at who supplies the tools, who sets the schedule, and who bears the risk, because those answers drive both the legal test and the practical fit for the job.
The wage stakes are concrete. Employees are entitled to minimum wage and overtime at one and a half times the regular rate for hours over forty in a week, and independent contractors are not. A misclassified crew that regularly works fifty-hour weeks builds a claim for unpaid overtime plus liquidated damages, and the claim follows the controlling facts rather than the contract label.
Document the Relationship From Day One
Documentation is the difference between a defensible classification and a guess. A written agreement should describe the scope of work, the deliverables, the payment schedule, and the responsibilities of each party, and the worker should sign it before starting. Records should be kept for at least three years, matching the IRS retention window for employment tax records.
- A written contract signed by both parties
- Proof of the worker’s business license and registration
- Certificates of insurance naming the builder as additionally insured
- A stated payment method, usually a flat fee per project
- Confirmation that the worker can take on other clients
- No requirement to attend company training or meetings
The paperwork extends to the site itself. Deciding who should apply for a building permit depends on whether the worker acts as the builder’s agent or as an independent firm, and a contract that states that role removes a common point of conflict during inspections.
What a Real Independent Contractor Looks Like
A genuine independent contractor runs a business, not a job. The worker typically works for multiple companies, supplies tools and materials, sets a schedule, hires assistants, and can profit or lose money based on how the work is managed. When those characteristics are present, the label matches the reality.
| Factor | Employee | Independent contractor |
|---|---|---|
| Training | Provided by the employer | Worker arranges own training |
| Tools and materials | Supplied by the employer | Worker supplies own |
| Schedule | Set by the employer | Worker controls |
| Pay | Hourly or salary with withholding | Flat fee per project, no withholding |
| Benefits | Eligible for employer benefits | Provides own benefits |
| Profit and loss risk | None | Bears own risk |
| Other clients | Usually one employer | Often several |
Workers who want contractor status should follow the same path as any trade business. How to become a construction contractor is a step-by-step process covering licensing, insurance, and business formation, and a worker who has not taken those steps rarely meets the tests.
Most states also run their own classification tests for unemployment insurance and workers’ compensation, and several states use an ABC test that presumes employment unless the worker is free from control, performs work outside the usual course of the business, and is customarily engaged in an independent trade. A worker can satisfy the federal tests and still fail a state test, so the compliance question is really two questions, federal and state.
The contrast shows up in the field. A crew of employees arrives together, uses the builder’s trucks and tools, works a set schedule, and follows the builder’s sequence; an independent contractor arrives with a contract, supplies his own equipment, and answers to the scope of work rather than the clock. When the two models work side by side on the same site, the difference is visible to anyone watching.
Independence in Practice: How Real Contractors Work
Independence is a practical matter, not a label. A contractor who cannot finish a job without the builder’s tools, staff, or daily direction is not truly independent, while a contractor who completes the scope, manages helpers, and invoices on a schedule behaves like the separate business the law assumes.
Think of it the same way designers think of accessible homes: a space only works when the user can manage without assistance, and the same standard applies to labor. A home built around universal design kitchens for independent living needs no helper for daily tasks, and a contractor arrangement needs no helper from the builder for daily direction.
- Can the worker perform the job without the builder’s equipment?
- Does the worker set the sequence and schedule of the work?
- Does the worker hire and pay any assistants?
- Does the worker work for other clients at the same time?
- Could the worker lose money on a fixed-price job?
The Cost of Getting It Wrong
Misclassification penalties compound quickly. The IRS can reclassify workers, collect unpaid payroll taxes, and add penalties and interest, and the Department of Labor can pursue overtime and minimum wage claims under the FLSA. State agencies add unemployment insurance, workers’ compensation, and wage claims, and a single audit can reach back several years.
The fix is the same discipline builders apply to buildings. Just as energy independent construction reduces a structure’s reliance on outside systems, a documented workforce model reduces the business’s reliance on favorable assumptions, and both are built deliberately rather than left to chance.
- List every worker engaged in the last twelve months and their classification
- Re-run the control factors for each role against the current contract
- Check state requirements, since many states run their own tests
- Update the written agreements before any job changes the working relationship
Review the classification of every worker at least once a year, and when a job changes, ask whether the change alters the test. A tax professional who knows construction can review the file in an hour, and that hour is cheaper than the first penalty notice.
