Plumbing and HVAC Worker Classification: Apprentices, Journeymen, and Subcontractors
The plumbing and HVAC trades have a structured workforce hierarchy: apprentices (learning the trade under supervision), journeymen (licensed technicians who work under a master’s license), and master plumbers/HVAC contractors (fully licensed, can pull permits and supervise journeymen and apprentices). The tax classification of each worker depends on the behavioral, financial, and relationship factors, but the structured nature of the trades pushes most workers firmly into employee status.
Apprentices are employees. Full stop. They work under the direct supervision of a journeyman or master, follow the company’s methods and procedures, use the company’s tools and materials, and work on the company’s schedule. No factor in the common-law test supports contractor status for an apprentice. Journeymen are typically employees when they work exclusively or primarily for one company, use the company’s van and tools, follow the company’s schedule, and are dispatched to jobs by the company. A journeyman who operates independently (has their own tools, their own vehicle, their own clients, works under their own license, and takes jobs from multiple companies) may be a legitimate subcontractor. Subcontractors in the trades are legitimate when they are licensed, carry their own insurance, provide their own tools and vehicle, control their own schedule, and bear the risk of profit or loss on a fixed-price contract. A “subcontractor” who shows up every day, drives the company van, and takes direction from the owner is an employee.
What are the consequences of misclassification?
When is a subcontractor legitimate?
A legitimate subcontractor in the plumbing or HVAC trade typically:
- Holds their own plumbing or HVAC license (journeyman or master)
- Carries their own general liability and workers’ compensation insurance
- Owns their own tools, equipment, and vehicle
- Pulls their own permits (if their license allows it)
- Contracts for specific jobs at a fixed price, not hourly
- Controls their own schedule (decides when to do the work, not just how)
- Works for multiple companies
- Bears the risk of profit or loss (if the job costs more than the contract price, the sub absorbs the loss)
A common legitimate arrangement: a plumbing company that needs extra capacity during a busy season hires a licensed plumber with their own van and tools to complete specific jobs on a per-job basis. The sub invoices the company, handles their own taxes, and has the freedom to decline jobs.

Can a worker be an independent contractor for one client and an employee for another?
Yes. Classification is determined relationship by relationship, not by the worker’s overall status. A graphic designer could be an employee of one company (working set hours, using company equipment, receiving benefits) and an independent contractor for another (setting their own schedule, using their own tools, controlling how the work gets done). The IRS applies the common-law test to each engagement separately: the degree of behavioral control, financial control, and the type of relationship all matter. What matters is the actual working relationship, not what the contract says. A contract calling someone an independent contractor does not override the economic reality.
What are the penalties for misclassifying employees as independent contractors?
The penalties are substantial and compound across multiple agencies. The IRS can assess the employer’s share of FICA (7.65% of wages), plus penalties of 1.5% of wages for failure to withhold income tax and 20% of the employee’s share of FICA. These penalties increase to 3% and 40% respectively if the misclassification is deemed intentional (no 1099s filed). State penalties add unemployment tax, workers’ compensation premiums that should have been paid (often with interest and penalties), and potential fines per misclassified worker. Misclassified workers can also claim overtime, minimum wage, benefits, and other protections they were denied under employment law. The IRS Voluntary Classification Settlement Program (VCSP) offers reduced penalties if you come forward before an audit.
