The employer's share of payroll tax comes to 7.65% of each employee's wages. That's 6.2% for Social Security and 1.45% for Medicare, plus federal unemployment tax on top. Social Security stops at the 2026 wage base of $184,500, while Medicare has no ceiling at all.
Every business with W-2 employees owes this tax, whether it has one worker or a hundred. State unemployment tax adds another layer, and rates vary by location. Missing a deposit or misclassifying a worker can trigger IRS penalties on top of the tax itself. Getting the math right from the start avoids both problems.

What the Employer Portion of Payroll Tax Covers
"Payroll tax" sounds like one flat number. The employer portion is a separate slice: what the business pays on top of wages. It breaks into two federal pieces: FICA (Social Security and Medicare) and FUTA (federal unemployment tax), plus a state layer most states require. These are 2026 federal rates, so check current numbers and state rules before filing, and treat this as a guide, not a stand-in for a payroll provider or accountant.
FICA has two parts, and the employer matches both. The employer's Social Security tax is 6.2% of wages, up to the annual wage base. That base rose to $184,500 for 2026, up from $176,100 the year before. The employer's Medicare tax is 1.45% of wages, with no cap at all, so it applies to every dollar earned.
That 7.65% employer share matches the 7.65% withheld from the employee's own check. Combined, that's 15.3% flowing to Social Security and Medicare on every eligible dollar. FUTA, though, works differently: it's an employer-only tax with no employee withholding at all. The FUTA tax rate is 6.0% on the first $7,000 of each employee's wages per year.
Businesses that pay state unemployment tax on time typically get a credit of up to 5.4%. That credit drops the effective FUTA rate to 0.6%, capping the tax near $42 per employee per year. Skip a state deposit deadline, though, and that credit can shrink or vanish, pushing the FUTA bill back toward the full 6%.
SUTA, or state unemployment tax, is the piece most employers underrate, since every state sets its own rate and wage base. In nearly every state, only the employer pays it, though a few states also require a small employee share. None of this SUTA, FICA, or FUTA math includes income tax, since that money was always the employee's, never the business's own.
Getting any of these numbers wrong carries a real cost, not only an accounting headache. Under-depositing FICA or missing a FUTA deadline can trigger IRS penalties on top of the tax owed, sometimes adding thousands of dollars. A business that overpays, on the other hand, ties up cash it could use elsewhere until it claims a refund. Treating this as a fixed cost of having staff, worked out correctly from the first paycheck, avoids both problems.
Which Situation Applies to You?
How much you owe depends on how the business is set up and who's on the payroll. A single business can match more than one situation below at once. Match your setup to the closest case, then check the worked math further down.
1099 Contractors Only, No W-2 Employees
A business that only pays 1099 contractors owes none of the employer payroll tax in this article. FICA, FUTA, and SUTA all attach to W-2 wages, not to a contractor's invoice. The contractor pays self-employment tax instead, covering both the employee and employer shares of Social Security and Medicare on their own return.
That's also why worker misclassification is such a costly mistake. Paying someone as a 1099 contractor when their job makes them a legal employee puts a real tax bill on the IRS's radar. The agency can claw back the unpaid employer share later, with penalties and interest added on. A shop that hires only freelancers can stay in this category, but one part-time W-2 hire triggers every rule in this article.
Small Business With a Few W-2 Employees
This is the most common case, and the math is the most direct. Every W-2 employee's wages generate the employer's 7.65% FICA share, FUTA on the first $7,000 they earn each year, and whatever SUTA rate the state sets. A five-employee shop pays this on each person separately, not once as a flat fee.
Underrating this cost catches many new employers off guard. A business that budgets only for gross wages, without the employer tax on top, can end up short by 8% to 10% of payroll. Build that percentage into every hiring decision from the start, not after the first deposit is due. A payroll percentage-of-revenue benchmark can help frame whether the total still fits the budget, before an offer letter goes out.
An Employee Earning Over $200,000
Once a single employee's wages cross $200,000 in a year, the Additional Medicare Tax enters the picture. The employee, not the employer, has an extra 0.9% withheld above that threshold. Employers do not pay a matching 0.9%, which is the single most misunderstood part of the employer payroll tax picture.
The employer's own Medicare math never changes. It stays 1.45% on every dollar of that employee's wages, with no extra amount kicking in past $200,000. The employer's Social Security bill still stops once wages cross the $184,500 wage base, well below the Medicare mark, so a business with one highly paid executive still owes only the standard 7.65% employer FICA rate on that pay. That 7.65% rate covers the executive's full salary, not only the amount above $200,000.
A Business Operating in Multiple States
A business with staff in more than one state must register for, and pay, SUTA separately in each state. Rates and wage bases differ by state, so the same job can carry a different tax bill depending on where the person works. A remote-first company with staff in five states manages five separate SUTA accounts.
Missing a state's registration deadline, or using the wrong rate for a remote worker, is a common, costly error for a growing business. Check each state's labor agency directly, since SUTA rates shift year to year and no single federal source lists them all. A payroll service that already tracks multi-state rules can earn its cost once a business reaches a second or third state.
What's Withheld From Employees vs. What Employers Pay
The phrase "payroll tax" hides a split that trips up many first-time employers. Part of it is money the employer pays outright, on top of wages. Part of it is money withheld from the employee's own check and simply forwarded to the government. Confusing the two makes it easy to under-budget for the true cost of an employee.
| Tax | Employer Pays | Employee Pays |
|---|---|---|
| Social Security | 6.2% up to the wage base | 6.2% up to the wage base |
| Medicare | 1.45%, no wage cap | 1.45%, no wage cap |
| Additional Medicare | None | 0.9% above $200,000 |
| FUTA | 6.0% (often 0.6% effective) | None |
| SUTA | Varies by state | Rare, a few states only |
Social Security and Medicare are the only two taxes split between both sides, each at a matching rate. FUTA and, in most states, SUTA are entirely employer-paid, with nothing withheld from any employee's check. Federal and state income tax withholding is different: it's the employee's own tax, set by their W-4, that the employer merely collects and forwards. None of that money belongs to the business, unlike the employer's own FICA and unemployment bills.
The most common misconception is treating the Additional Medicare Tax as another employer expense. It is entirely an employee-side withholding. A worker who crosses $200,000 sees an extra 0.9% come out of their own check, never matched by the employer. Employers who budget for a phantom 0.9% match on high earners are simply overstating their own payroll tax bill.
Picture a $90,000 employee to see the split in practice. The business pays $6,885 in employer FICA on that salary, money that never touches the employee's own check. The employee separately sees $6,885 withheld from their pay for the matching employee half, plus whatever income tax their W-4 sets. Two nearly identical numbers, one paid by the business and one paid by the worker, is the exact confusion this section clears up.
Worked Example: Calculating the Employer's Payroll Tax Bill on a $50,000 Salary
Here's the full math for one employee earning $50,000 a year, paid steadily with no bonus that crosses a threshold. This example assumes state unemployment tax is paid on time, which earns the business the full FUTA credit. Swap in your own salary and state SUTA rate to check your own numbers.
The employer's Social Security share is 6.2% of $50,000, which comes to $3,100 for the year. The employer's Medicare share is 1.45% of $50,000, adding $725 more, since Medicare has no wage cap at this income level. Combined, the employer's FICA share alone is $3,825, before FUTA is even added.
FUTA applies only to the first $7,000 of this employee's wages, not the full $50,000 salary. At the effective rate of 0.6%, after the standard state credit, that adds $42 to the bill. Without that credit, the same $7,000 would generate $420 in FUTA instead, a $378 gap tied to paying state tax on time.
Add it up, and this $50,000 employee costs the business $3,867 in employer FICA and FUTA, on top of gross wages. That figure still excludes SUTA, since the amount depends on the state and the business's own claims history. For comparison, the employee's own check sees the same $3,825 withheld for FICA, well under both the wage base and the $200,000 Additional Medicare mark.
| Line Item | Employer Cost |
|---|---|
| Social Security (6.2%) | $3,100 |
| Medicare (1.45%) | $725 |
| FUTA (effective 0.6%) | $42 |
| Total employer FICA + FUTA | $3,867 |
Scale this same math to any salary using the 7.65% employer FICA rate. A $30,000 employee generates $2,295 in employer FICA, plus up to $42 in FUTA, for a total near $2,337. A $75,000 employee generates $5,737.50 in employer FICA alone, still well under the $184,500 wage base, with FUTA adding its usual small amount on top.
Lessons From Employers Who Got the Employer Share Wrong
Three employers learned different parts of this system through hard experience, each catching a different mistake before it grew costly. None of these repeats the math already covered above. Each one teaches something new about how the employer portion behaves in practice.
Elena's Marketing Agency and the Additional Medicare Mix-Up
Elena runs payroll for a 35-person marketing agency, and one of her account directors crossed $200,000 in pay for the first time. Elena assumed the agency owed its own matching 0.9%, mirroring how it matches the regular 1.45% Medicare rate. She flagged an extra $450 in the payroll budget the business never owed.
A quick check against current payroll guidance corrected the assumption. The Additional Medicare Tax is withheld from the employee alone, with no employer match at any income level. Elena's agency still paid its standard 1.45% Medicare rate on the director's full salary, nothing more. She now flags every crossing of the $200,000 mark as an employee-side change only, never a line item for the employer budget.
| What Elena Assumed | What Was True |
|---|---|
| The employer matches the extra 0.9% Medicare | Additional Medicare Tax is employee-withheld only |
| High earners cost more in employer Medicare tax | Employer Medicare stays 1.45% at every income level |
Marcus's Landscaping Company and the Lost FUTA Credit
Marcus owns a landscaping company with twelve seasonal crew members. He fell behind on his state unemployment tax deposits during a slow winter, then paid them three months late once cash flow recovered. He assumed the delay only hurt his standing with the state, not his federal FUTA bill.
Paying state tax late cost Marcus the FUTA credit entirely, pushing his rate from 0.6% back up to the full 6.0%. Across twelve employees earning at least $7,000 each, that mistake added roughly $4,536 to his federal bill for the year. Marcus now treats the state deadline as the one date that protects his FUTA credit, not a minor formality.
| Marcus's Situation | Effective FUTA Rate |
|---|---|
| State unemployment tax paid on time | 0.6%, with the full credit |
| State unemployment tax paid late | Up to 6.0%, credit lost |
Owen's Courier Business and the Multi-State Surprise
Owen runs a same-day courier business that started in one state, then expanded into a neighboring one within a year. He kept paying SUTA under his original state's account for every driver, including the ones now based across the line. He didn't realize each state needs its own separate registration and rate.
The gap surfaced when the second state flagged unpaid tax on Owen's out-of-state drivers, plus interest for the months they went unregistered. Owen had to register late, then sort out nearly a year of misapplied SUTA payments between the two states. He now checks the labor agency in every state where a driver works, before that driver's first paycheck, not after. Owen also built a short checklist for his bookkeeper, so a new state gets a SUTA account the same week a driver starts there.
Filing Deadlines: Form 941 and Form 940
Two federal forms carry the employer portion of payroll tax to the IRS. Confusing their schedules is a common early mistake. Form 941, the Employer's Quarterly Federal Tax Return, reports withheld income tax plus both shares of Social Security and Medicare. It's filed four times a year, once per quarter, and deposits toward the tax owed run on a separate, more frequent schedule.
Form 940 covers FUTA and is filed once a year, reporting the employer's federal unemployment tax for the prior twelve months. Most employers must also make FUTA deposits during the year, once the amount owed crosses a set threshold, rather than paying it all at once. Exact due dates shift around weekends and holidays, so check the current deposit schedule rather than assume last year's calendar still applies.
Filing late costs more than a flat fee. The IRS penalty structure builds in stages, starting at a percentage of the unpaid tax and growing the longer it stays outstanding. A business that can't pay in full by the deadline should still file on time, since a late deposit and a late return draw separate penalties. Many small businesses hand this schedule to a payroll provider to avoid tracking two federal calendars by hand.
State unemployment tax carries its own filing calendar, on top of the two federal forms. Most states want a quarterly SUTA return alongside their own deposit schedule, filed with the state's labor agency rather than the IRS. That calendar is state-specific, so check your own state's agency directly rather than assume it matches the federal quarter. A business handling payroll itself still has to track all three calendars, state, Form 941, and Form 940, with no built-in reminders.
Do
- Set aside 8% to 10% of gross wages for employer payroll tax when budgeting a new hire, since FICA, FUTA, and SUTA combined regularly land in that range
- Confirm your state's SUTA rate every year, since states reset employer rates annually based on claims history and the fund balance
- Pay state unemployment tax on time every quarter, since that habit alone protects the full FUTA credit
- Track each employee's wages against the Social Security wage base, so withholding stops on its own once they cross $184,500
- File Form 941 every quarter even when a deposit is short, since filing late and paying late draw separate, stacking penalties
- Register for SUTA in every state where an employee works, not only where the business is based
Don't
- Assume the employer matches the extra 0.9% Additional Medicare Tax, since that amount is withheld from the employee alone
- Classify a worker as a 1099 contractor to dodge employer payroll tax, since misclassification penalties can exceed the tax that was avoided
- Wait until Form 941 is due to reconcile deposits, since small errors compound every quarter they go unnoticed
- Skip a state's unemployment tax deposit deadline, even in a slow season, since it can cost the full FUTA credit for the year
- Treat SUTA as one national rate, since every state sets its own rate and wage base
- Forget that a bonus or commission is taxed the same as regular wages for FICA and FUTA, unless a wage cap is already reached
Pros and Cons of Handling Payroll Tax In-House vs. Using a Payroll Service
Pros
- Handling payroll tax in-house keeps full control over timing and cash flow, since deposits happen exactly when the business schedules them
- An in-house process skips a monthly per-employee service fee, which matters more for a small headcount
- Owners build first-hand knowledge of their own obligations, which helps catch an error a hands-off provider might miss
- In-house handling makes it easier to spot an unusual pay situation, like a sudden bonus, before it causes a filing mistake
- There's no dependency on a third party's software staying online during a filing deadline
Cons
- A missed federal deposit or filing deadline falls entirely on the owner, with no provider backstop catching it first
- Multi-state SUTA rules are easy to get wrong without dedicated software tracking each state's rate and deadline
- Calculating the Additional Medicare Tax correctly, once an employee crosses $200,000 mid-year, takes a manual step many owners forget
- An in-house process rarely catches a misclassified worker until an audit reveals it, since no second reviewer checks every hire
- Time spent on payroll tax math is time not spent running the business, and that trade-off grows as headcount grows
Mistakes to Avoid With the Employer Portion of Payroll Tax
- Assuming the employer matches the Additional Medicare Tax. This inflates the payroll budget with a cost the business never owes.
- Missing a state unemployment tax deposit deadline. This can erase the FUTA credit and push the effective federal rate from 0.6% up to 6.0%.
- Forgetting to stop Social Security withholding at the wage base. Overwithholding ties up cash and creates a correction headache with every affected employee.
- Misclassifying an employee as a 1099 contractor. The IRS can reclaim years of unpaid employer FICA, plus penalties and interest, once discovered.
- Registering for SUTA in only one state for a multi-state workforce. Unregistered states can assess back taxes and interest once they catch the gap.
- Filing Form 941 late, even by a few days. Late-filing penalties stack on top of any late-payment penalty already owed.
- Budgeting only for gross wages, not the employer tax on top. A new hire can cost 8% to 10% more than the salary line alone suggests.
- Ignoring FUTA on seasonal or part-time employees. FUTA applies to nearly every wage earner, not only full-time year-round staff.
- Skipping a professional review after a big payroll change. A merger, a new state, or a highly paid new hire can shift obligations an in-house process misses.
What to Do Next
- Calculate your current employer payroll tax rate, 7.65% FICA plus your state's SUTA rate, using the worked example above as a template.
- Confirm your state's current SUTA rate and taxable wage base with your state's labor agency.
- Check whether any employee is nearing the $184,500 Social Security wage base or the $200,000 Additional Medicare mark this year.
- Set a recurring reminder for every state unemployment tax deposit, since a missed one can cost the full FUTA credit.
- Mark your Form 941 quarterly dates and your Form 940 annual date on a shared calendar.
- Decide whether to keep payroll tax in-house or move to a payroll service, based on headcount and how many states you operate in.
- Bring in a payroll provider or accountant if your business recently crossed into a new state, added a highly paid employee, or is unsure about a past deposit.
Frequently Asked Questions
How much is the employee's share of payroll tax?
It's also 7.65% of wages, up to the Social Security wage base, split into 6.2% for Social Security and 1.45% for Medicare, matching the employer's own rate dollar for dollar.
Does a sole proprietor pay the employer portion of payroll tax?
Yes, indirectly, through self-employment tax. A sole proprietor with no W-2 employees pays both the employer and employee shares alone, currently totaling 15.3% of net self-employment earnings.
Is the employer portion of payroll tax deductible?
Yes. The employer's share of FICA and FUTA counts as an ordinary, deductible expense, separate from wages, on the business's federal return.
Do part-time employees count for employer payroll tax?
Yes, for FICA on every dollar earned. FUTA and SUTA apply too, though some states set a minimum-earnings threshold before SUTA kicks in for a part-time worker.
Does an LLC owner's pay count toward the employer portion?
Only if the owner is paid as a W-2 employee. Whether that's required depends on the LLC's tax setup, a detail this guide to how LLC owners get paid explains further.
What happens if an employer doesn't pay its payroll tax?
The IRS can assess steep penalties and interest, and in serious cases pursue the owner personally, since trust-fund taxes carry personal liability regardless of legal structure.
Can the employer portion of payroll tax change during the year?
Yes, once an employee's wages cross a threshold. Social Security stops at the annual wage base, while Additional Medicare withholding starts on the employee's side above $200,000.
Do nonprofits pay the employer portion of payroll tax?
Most do, for FICA at least. Many nonprofits qualify for a FUTA exemption, though state rules for nonprofit unemployment tax vary and should be confirmed with the state agency.
How is the employer portion of payroll tax paid?
Through periodic federal tax deposits, usually electronic, made outside the quarterly Form 941 filing, on a schedule the IRS sets by payroll size.
Does the employer portion of payroll tax apply to bonuses?
Yes, the same as regular wages. A bonus draws the same Social Security, Medicare, and FUTA rules as salary, unless it pushes total pay past a wage cap already reached.
Is the Additional Medicare Tax part of the employer's cost?
No. It is withheld entirely from the employee's check once wages pass $200,000, with no employer-side match required at any income level.
Can a small business get help calculating its payroll tax?
Yes, from a payroll provider or accountant. Most payroll software calculates the employer portion on its own, though an unusual pay structure should still get a professional's check.
