The cost employee turnover contractors absorb includes payroll taxes, lost billable hours, and training wages that never get billed to a job. Most owners see the recruiting fee and miss the rest. In 2026, with the Social Security wage base at $184,500, every replacement W-2 employee triggers a fresh round of employer payroll taxes on wages up to that ceiling. That is real money coming out of job margin.

I see this most often in trades with small crews. One lead carpenter leaves, and the project slows down for three weeks while a new person learns the site, the foreman's expectations, and your tooling. During that gap, you still pay the new person's wages, you still pay the crew that is carrying them, and you may miss the window to start the next job. None of that shows up as a line item called turnover, but it is everywhere in the P&L.

What does employee turnover actually cost a contractor?

It costs more than the want ad. You pay to find the person, pay to onboard them, pay payroll taxes on their wages, and pay again in lost productivity until they are fully billable. For a contractor running tight margins, one unexpected departure can flip a profitable job into a breakeven mess.

The hard costs are easy to add up. Job board ads, recruiter fees, referral bonuses, background checks, and drug screens all come out of your checking account. The soft costs hurt more. A rookie slows the crew. Material gets ordered wrong. Customer callbacks rise. If you turn down work because you are short-handed, that opportunity cost is part of the price too.

Every one of those expenses is deductible under IRC §162 as an ordinary and necessary business expense. But a deduction only saves you a fraction of the outlay. A dollar out the door is still a dollar out the door, even if the IRS lets you write off thirty-five cents of it.

Which replacement expenses are tax deductible?

Nearly all of them. Recruiting fees, advertising, training materials, safety gear issued to the new hire, and the wages you pay them during non-billable onboarding are all valid deductions. The rule is simple: if the expense is common in your trade and helpful to your business, it clears the ordinary and necessary standard.

If you pay a signing bonus to lure someone away from a competitor, that is wages. Run it through payroll, withhold income and FICA taxes, and report it on their W-2. Do not cut a separate check and call it a draw. The IRS treats cash or cash-equivalent incentives as compensation.

Education is trickier. If you send a new electrician to a code-update seminar to maintain their skills, the tuition is deductible. If you pay for coursework that qualifies them for a new license or trade, that is a personal capital expense and not deductible by your company.

How do payroll taxes add to the cost of replacing an employee?

There is no free pass for replacement hires. You pay the employer share of Social Security tax on every dollar of wages up to the 2026 wage base of $184,500. You pay the employer share of Medicare tax on every dollar with no cap. State unemployment insurance taxes also restart. On a mid-level wage, that is thousands of dollars in payroll tax before the replacement bills their first hour.

Here is how the math works on a $65,000 replacement in 2026. Social Security tax applies to every dollar up to the wage base. Medicare tax applies to all $65,000. State UI typically hits the first several thousand dollars of wages, and the rate often spikes if your state experience rating has climbed from past claims. Add the administrative cost of running payroll and filing the quarterly returns. That stack is entirely new money you would not have spent if the original employee had stayed.

Is it cheaper to hire a 1099 subcontractor instead of replacing a W-2 employee?

Only if the person is genuinely a subcontractor. If they show up when you say, use your tools, and wear your logo, they are an employee under IRS common law rules. Calling them a 1099 to dodge payroll taxes is misclassification, and the penalties will erase every dollar you thought you saved plus interest. For the full test, see our breakdown of 1099 vs W-2 for contractors.

A true subcontractor brings their own tools, sets their own schedule, and serves other clients. You pay them gross, file a Form 1099-NEC if you pay them $2,000 or more in 2026, and you owe no payroll taxes. The trade-off is control. You cannot dictate their hours or methods, which is a poor fit for crew work that needs to move in lockstep.

If you are deciding between hiring a W-2 employee and using a sub for a specific role, run the numbers properly. Our guide on employees or 1099 subs walks through the tax and legal risks side by side.

How do you track turnover cost against a job?

You load every dollar of replacement cost into the job where the turnover happened. That means recruiting fees, the excess labor hours the crew worked to cover the gap, and the wages paid during training all hit that project's job cost report. Only then do you see whether the job was actually profitable.

Most contractors dump hiring costs into overhead and wonder why every job looks good but the bank account does not. Overhead is real, but it should not hide the cost of a foreman who walked off in week three. If you track by job, you know which projects and which crew leaders are bleeding people. Job costing for contractors is the tool that makes this visible.

What actually stops turnover?

Pay at market rate or above, and make the pay structure predictable. Promote from within so apprentices see a path to journeyman and lead. When you grow your own people, training time drops because they already know your systems, your customers, and your tooling.

Benefits matter, even in small shops. In 2026, you can offer a Health FSA with an annual limit of $3,400. Employees set aside pre-tax dollars for medical expenses, which lowers their taxable income and costs you almost nothing to administer. That is cheap retention leverage compared to losing a trained crew member and paying to replace them.

Track turnover by crew, not just by company. One bad foreman can drive out three people a year while another crew stays intact. If you only look at company-wide averages, you miss the localized problem. Address the foreman or change the site conditions before you blame the labor market.

When should you bring in help to fix the numbers?

When your labor cost percentage is climbing but your prices are not, or when you cannot tell if a job was profitable after a mid-project crew change. A good accountant or bookkeeper sets up a chart of accounts that splits labor by job, tracks burdened rates, and flags margin erosion before it becomes a cash flow crisis.

Turnover is a tax problem too. Every replacement hire restarts the payroll tax clock. Every rushed hire increases misclassification risk. Every training hour that gets buried in overhead distorts your bidding on the next job. Fix the retention problem and the tax and profit problems get easier.
