Subcontractor vs. Independent Contractor vs. Employee: What's the Difference?

A subcontractor is a business you hire for a defined scope of work, an independent contractor is a self-employed individual you pay to do work, and an employee works under your direction on your payroll. The labels overlap on a job site, but the tax and legal consequences differ sharply — and getting it wrong is one of the costliest mistakes a trade business can make.

The three classifications, in plain terms

These terms get used loosely in the field, but they describe genuinely different relationships.

• Employee — Someone on your payroll. You direct how, when, and where they work. You withhold taxes, pay the employer share of payroll taxes, carry workers' comp on them, and typically supply tools, training, and a steady schedule. They get a W-2.
• Independent contractor — A self-employed individual you pay to do work, but who controls how they do it. They run their own operation, set their own hours, often work for multiple clients, and handle their own taxes. In the U.S. they get a 1099 instead of a W-2.
• Subcontractor — Almost always a business (which may be one person or a full crew) hired to complete a defined scope under a contract. A subcontractor is a type of independent contractor relationship, but at the business-to-business level. The electrical sub on a job runs their own company, carries their own insurance, and is answerable for a deliverable — not for clocking hours.

The short version: "subcontractor" describes the commercial relationship (one business hires another), while "independent contractor vs. employee" is the classification question that tax agencies and labor departments actually care about. (For more terms, see the glossary.)

Why does classification matter so much?

Because the cost and risk sit in very different places depending on the answer.

When you hire an employee, you take on payroll taxes, unemployment insurance, workers' comp premiums tied to their wages, and a long list of labor-law obligations. When you hire a subcontractor or independent contractor, those costs sit with them — they carry their own insurance, pay their own taxes, and are responsible for their own crew.

That difference is exactly why misclassification is a problem. If you treat someone as a 1099 sub but a regulator later decides they were really functioning as an employee, you can be on the hook for back payroll taxes, penalties, interest, unpaid overtime, and workers' comp exposure for the whole period. It's not a paperwork technicality — it's a financial liability that can land years after the work is done.

This is general information, not legal or tax advice. Classification rules vary by federal agency, by state, and by the specific test applied, so check with a CPA or employment attorney for your situation.

The factors that decide it: control, tools, and integration

No single factor settles classification. Agencies look at the total relationship. But across most tests, the same themes show up again and again.

1. Behavioral control

Who decides how the work gets done? If you dictate the methods, set the hours, require specific procedures, and supervise the day-to-day, that points toward an employee. If the worker decides how to deliver the result and you only care that it meets spec, that points toward an independent business.

2. Financial control

Does the worker have a real chance of profit or loss? Do they invest in their own equipment, advertise their services, and work for other clients? An independent contractor runs a business and can make or lose money on a job. An employee just earns a wage.

3. Who supplies the tools and materials

This one is concrete and contractors feel it daily. A worker who shows up with their own truck, tools, insurance, and crew looks like an independent business. A worker who uses your tools, your truck, and your materials, on your schedule, looks like an employee.

4. Integration and permanence

Is the work a core, ongoing part of your operation, or a defined project with an end? A framer you keep busy year-round, exclusively, starts to look like an employee no matter what the paperwork says. A sub you bring in for a three-week scope on one project looks like what they are.

A note on stricter tests

Some states apply a tougher standard (often called an "ABC test") that presumes a worker is an employee unless you can prove a short list of conditions — typically that the worker is free from your control, performs work outside your usual business, and is independently established in that trade. Under those rules, hiring a framing crew as "subs" when framing is your core business can be hard to defend. Know which test applies where you operate.

What this means for a trade business

For most trade-to-trade work, the relationship you want is a clean business-to-business subcontractor arrangement: a real company, with its own insurance, hired for a defined scope under a written agreement. The cleaner that line, the easier classification is to defend.

Practical habits that keep the line clean:

• Hire businesses, not warm bodies. Confirm the sub operates as a real entity with its own certificate of insurance and licenses.
• Put the scope in writing. A subcontractor agreement that defines deliverables — not hours supervised — reinforces the independent relationship.
• Let subs control their own methods and crew. The more you direct the how, the more it looks like employment.
• Keep records. COIs, signed agreements, and a clear paper trail matter if anyone ever asks.

This is one reason SKILLS anchors participation to organizations rather than individuals. Every Posting, every Coverage Offer, and every locked-in Work Agreement happens business-to-business, with the sub's insurance and verification tier visible in the Compliance Vault. It doesn't make the classification decision for you — but it keeps the relationship structured the way a legitimate sub arrangement should be, with an audit trail to match. (See how it works.)

Quick answers

Is a subcontractor the same as an independent contractor? Not exactly. A subcontractor is usually a business hired to complete a scope of work, while "independent contractor" is the broader classification for any self-employed individual you pay via 1099. A subcontractor relationship is a business-to-business form of independent contracting.

What's the main difference between an employee and a 1099 worker? Control. An employer directs how, when, and where an employee works, withholds their taxes, and carries workers' comp on them. A 1099 worker controls their own methods, supplies their own tools, works for multiple clients, and handles their own taxes.

What happens if I misclassify a worker? You can be liable for back payroll taxes, penalties, interest, unpaid overtime, and workers' comp exposure for the entire period — often years later. The fix is cheaper than the penalty: classify correctly up front.

Who decides if someone is an employee or a contractor? Tax agencies (like the IRS) and state labor departments, using factor-based tests centered on control, financial independence, who supplies tools, and how integrated the work is into your business. Different agencies and states apply different tests.

The bottom line

Subcontractor, independent contractor, and employee describe three different relationships — and the one you're actually in is decided by how the work happens, not by what you call it. The safest path for a trade business is a clean, business-to-business subcontractor arrangement: a real company, its own insurance, a written scope, and control over its own methods. When in doubt, get advice from a CPA or employment attorney before the work starts.
