What does one employee cost you in federal payroll tax?

Three federal rates, three different bases, and no single percentage. Enter one wage and watch the caps do the work.

Enter one employee's gross wage for the year. The default is a placeholder rather than a benchmark, and the number below is not about your business until you have replaced it — which is the point, because the answer moves when the wage does.

Employer payroll tax floor

Federal statutory minimum on this wage, for the year
$4,632 per employee
Arithmetic
Step Working Result
Gross wage for the year $60,000 $60,000
Social Security — 6.2% of wages up to $184,500 $60,000 × 0.062 $3,720
Medicare — 1.45% of all covered wages, uncapped $60,000 × 0.0145 $870
Federal unemployment — 0.6% of the first $7,000, after the maximum state credit $7,000 × 0.006 $42
Federal statutory minimum for the year $3,720 + $870 + $42 $4,632
What that is as a share of this wage — and it moves when the wage does $4,632 ÷ $60,000 7.72%

This assumes

  1. will not include state unemployment tax, which is experience-rated and set by fifty separate authorities, so no national figure exists to put here

    will apply only the three federal components the administering authority publishes rates for, and say on the page that a real employer pays a state rate on top of them

  2. will not include workers' compensation, which is legally required in nearly every state and is priced by state and by class of work rather than by a federal rate

    will leave it out entirely rather than substitute an average, so the output is a federal floor and not a total of what law requires

  3. will not include insurance, retirement, paid leave or supplemental pay, none of which any statute requires an employer to provide

    will stay inside what is written into federal tax law, so nothing here depends on a survey, a sample or an average of other employers

  4. will not assume the federal unemployment rate before the state credit, which is the larger of the two figures the authority publishes

    will apply the rate after the maximum credit, which assumes state unemployment tax paid in full and on time in a state that has not been determined to be a credit reduction state — the smaller number, and the wrong one if any of that is untrue

  5. will not add the three rates together into one percentage of salary, which is how this figure is usually quoted

    will compute each component against its own base and sum the dollars, because two of the three stop at a cap and adding rates that stop at different points produces a percentage that is true for almost nobody

How to read this number.

Every number in this calculation except the wage is written into federal tax law, so unlike most things on this site there is no sample, no survey and no margin of error. What there is instead is three bases. Social Security is charged on wages up to an annual limit and nothing above it. Medicare is charged on all covered wages with no limit at all. Federal unemployment tax is charged on the first $7,000 you pay each person in the year and stops there. The rates are constants; the bases are what make the answer depend on the wage.

That is why this page is a calculator rather than a percentage. Add 6.2 and 1.45 and 0.6 together and you get a figure that is exactly right for an employee paid no more than $7,000 for the year and too high for every other employee alive. At a wage a few times that, the federal unemployment component has already flattened into a fixed forty-odd dollars while the other two keep growing, and the share of the wage starts falling. Above $184,500 the Social Security component flattens too, and the share falls faster. Type two different wages into the box and the output as a share of pay will not be the same number twice.

The result is a floor, not a total, and it is a floor in four separate directions. There is no state unemployment tax in it, because fifty authorities set that separately and by experience rating, and no national figure exists that would not be a guess. There is no workers' compensation in it, which is legally required in nearly every state and is priced by the work being done rather than by a rate anyone publishes federally. There is nothing discretionary in it — no insurance, no retirement, no leave. And the federal unemployment rate used is the one after the maximum state credit, which is the smaller of the two published and is conditional on having paid the state on time.

So the honest reading of the output is: whatever an employee costs you above the wage, it is at least this, and the gap between this and the real figure is made of things nobody publishes a national number for. That is a less satisfying answer than a multiplier, and it is the one that survives contact with a payroll. An employer who wants the whole figure can get it from their own records in an afternoon, and it will beat any national average, including the ones we publish ourselves.

One more thing about the last step. The share of the wage this produces is not a figure anyone published — it is the arithmetic run on your wage, and it exists only because you supplied one. The government publishes rates on defined bases and does not publish a share of a payroll, and that distinction is the reason the benchmark page behind this tool refuses to state one. Here it can be computed because there is a wage to compute it against, and it changes the moment the wage changes, which is the whole argument.

Questions this raises.

Why is there no state unemployment tax in this?

Because it is experience-rated. Every state sets its own rates and its own wage base, and within a state an employer's rate depends on its own history of claims. There is no national figure to put in a formula, and inventing one would be the only unsourced number on the page. It is a real cost and it is missing here, which is why the output is described as a floor.

Is the employee's half in this number?

No. This is the employer's side only. The employee pays the same Social Security and Medicare rates again out of their own pay, and there is an additional Medicare tax on high individual earnings that the employer does not match at all. None of that is an employer cost, so none of it is counted here.

Why does the percentage go down as the wage goes up?

Because two of the three components stop. Federal unemployment tax stops after the first $7,000 of a person's wages for the year, and Social Security stops at the annual wage base. Past those points the wage keeps rising and those two components do not, so the total is a smaller and smaller share of the pay. This is the mechanism that makes a single statutory percentage impossible to publish.

Where do the rates come from?

Both IRS tax topic pages, read end to end by our research engine on the day the figures were verified, with the source and its review date printed under the instrument. The rates and the bases they apply to are recorded together as sourced constants, so a change to either one stops this page building until the calculator follows it.

Evidence
Kind Claim Check it against
RegulationThe federal unemployment component is bounded per employee rather than proportional to pay: it applies only to the first wages of the year for each person, so an employer's liability for it is set by headcount and not by payroll.The IRS tax topic for federal unemployment tax, which states the rate and the per-employee wage base the tax applies to, and the annual federal unemployment tax return it is reported on.
ConstraintThe lower federal unemployment rate is conditional and can be lost: it requires state unemployment tax paid in full and on time on the same wages, in a state that has not been determined to be a credit reduction state, and the authority republishes that list every year.The credit reduction state list the IRS publishes annually alongside the federal unemployment tax return instructions.

Each row would be wrong on another industry's page. Where a sourced figure exists it is in the table above instead; these are the constraints that shape the work and do not happen to be numbers.
