How to Give Your Drivers a Raise Without Raising Pay

If you run a fleet, you already know the math on driver pay. A heavy and tractor-trailer truck driver earns roughly $57,440 a year (BLS Occupational Employment and Wage Statistics, heavy and tractor-trailer truck drivers, May 2024), and the truck behind that driver does not move freight without them. When a competitor down the highway dangles a few more cents per mile, you feel it.

Here is the problem with answering a poaching offer by simply raising the pay: every dollar you add to gross pay also adds to your payroll tax bill, and the driver only keeps part of the raise after taxes come out. You spend more, they keep less, and the gap goes to taxes. There is a quieter lever that moves take-home pay up without touching the pay line at all, and it lowers your costs while it does. This piece walks the numbers for a 25-driver carrier.

The lever: pre-tax dollars

The mechanism is simple. When a driver pays for eligible benefits before payroll taxes are calculated, that amount comes out of their taxable wages. Lower taxable wages mean less federal income tax withheld and less FICA withheld. The driver’s gross rate is unchanged, but more of each paycheck survives to the bottom of the stub.

The same lower taxable-wage figure flows to your side of the ledger. Employer FICA is 7.65%: 6.2% for Social Security plus 1.45% for Medicare, set under IRC section 3111. (The Social Security portion applies up to the 2026 wage base of $184,500 per SSA, which most single-driver wages sit below.) When a driver’s taxable wages drop, the wages you owe FICA on drop too. You are not writing a check for the savings. The bill just gets smaller.

That is the dual benefit: the employee’s take-home goes up and the employer’s tax cost goes down, from the same dollars.

A worked example: one driver

Say one of your company drivers routes an illustrative $5,400 a year through pre-tax benefits. To keep it concrete, picture that as their share of the health premium plus a Health FSA contribution. The FSA portion stays at or below the 2026 Health FSA limit of $3,400 (IRS Rev. Proc. 2025-32), so the contribution is within the legal cap, and the combined $5,400 is the illustrative figure for this example.

Your employer FICA savings on that driver:

7.65% x $5,400 (illustrative) = about $413 per driver, per year

That $413 is money you keep, not money you spend. It is the FICA you would otherwise owe on wages the driver chose to route pre-tax instead.

On the driver’s side, the same $5,400 drops out of taxable wages, so their federal income tax withholding and their 7.65% FICA withholding both go down. The exact take-home increase depends on the driver’s bracket and filing status, which is why we do not put a single dollar figure on it here. The direction is not in doubt: less tax withheld means a bigger net check, with no change to the per-mile or hourly rate you advertise.

Scaling to a 25-driver carrier

Now run the same illustrative $5,400 across a 25-driver carrier:

$413 per driver x 25 drivers = about $10,325 per year in employer FICA savings

About $10,325 a year that stays in the business, recurring, with no pay increase attached. And every one of those 25 drivers is taking home more on the same gross pay. You have effectively delivered a raise that costs you less than zero, because your own tax bill went down in the process.

That reframes the retention conversation. Instead of matching a competitor’s cents-per-mile with cents-per-mile (which you partly fund and partly hand to the IRS), you can move net pay in the direction your drivers actually feel, at the kitchen table, while trimming overhead.

Where the bigger numbers live

The Health FSA is only one pre-tax bucket. For 2026 there is also the Dependent Care FSA at $7,500, and HSAs at $4,400 for self-only coverage and $8,750 for family coverage (IRS Rev. Proc. 2025-19) when paired with the right health plan. A driver with kids in daycare or a family on an HSA-eligible plan can route more pre-tax, which compounds both the take-home gain and your FICA savings. The Health FSA also allows a carryover of up to $680 into the next year, so unused dollars are not entirely lost.

We will not re-run the full per-bucket breakdown here. If you want the deep version with the structure built for trades and operators, see our companion piece, Section 125 for Skilled Trades Contractors and the FICA Savings math.

One honest caveat

This tax treatment is not automatic. It depends on the benefits being offered through a properly structured and administered plan that meets the IRS rules. Get the structure wrong and the savings do not hold. Benefits Genius provides education, not tax, legal, or insurance advice, and the figures above are illustrative examples built only on published IRS, SSA, and BLS limits, not a quote for your fleet.

Your next step

The fastest way to see your own number is to run it. Use our FICA savings estimator to plug in your driver count and a realistic pre-tax figure, and the 7.65% math will show you roughly what stays in the business each year.

From there, a licensed advisor can sit down with your fleet and lay out the options: which pre-tax buckets fit your drivers, how the plan would be structured, and what the take-home change looks like for the drivers you most want to keep. No pitch, just the numbers for your specific fleet, so you can decide.
