Hiring Employees vs. Subcontractors in Your Plumbing Business: The Financial Impact

As your plumbing business grows, you'll need help on jobs — and you'll face the foundational decision of how to structure that help: employees or subcontractors? Most plumbing business owners think about this in terms of control and flexibility, but the financial and tax implications are equally important.

The True Cost of an Employee

When you hire a plumber as an employee at $30/hour, your actual cost is substantially higher:

• FICA taxes (employer's share): 7.65% = $2.30/hour
• Federal and state unemployment taxes (FUTA/SUTA): approximately $0.50–$1.00/hour on average
• Workers' compensation insurance: rates vary, but plumbing is high-risk — often 10–20% of wages
• General liability insurance increase
• Benefits (if any), tools, uniforms, vehicle

A $30/hour employee costs a plumbing business $36–$42/hour in total labor cost. This is not a reason to avoid employees — it's a reason to price jobs correctly to cover it.

The True Cost of a Subcontractor

Subcontractors seem cheaper because you don't pay payroll taxes or benefits. But they often charge more per hour/project to cover their own overhead. And they come with limitations: you can't control how they do the work as closely, they may work for competitors, and their availability isn't guaranteed.

Worker Classification Risk

The IRS uses a multi-factor test to determine whether a worker is truly an independent contractor. If a worker works exclusively for you, uses your tools, follows your schedule, and performs work that is central to your business, they may legally be an employee — regardless of what your contract says. Misclassification penalties include back payroll taxes, interest, and penalties.

The Right Model Depends on Your Work Mix

Many plumbing businesses use a hybrid: core employees for routine service work where consistency and brand reputation matter, and occasional subcontractors for overflow work or specialty jobs (like commercial HVAC connections or underground work).

Payroll Administration for Plumbing Employees

Running payroll means calculating wages, withholding income taxes, calculating FICA, filing quarterly 941 forms, and issuing W-2s at year-end. This is manageable with the right payroll software and bookkeeper — but it requires consistent attention.
