Yes, employers pay taxes on bonuses. Every bonus you issue triggers the employer’s own share of Social Security and Medicare tax, and potentially federal and state unemployment tax, all paid from company funds on top of what you withhold from the employee’s check. On a $10,000 bonus, the employer’s Social Security and Medicare share alone adds at least $765 to the cost, and unemployment taxes can push it higher.
The Employer’s Matching FICA
The IRS treats bonuses as supplemental wages, a category that covers any pay beyond regular salary or hourly rate.1Internal Revenue Service. Publication 15 – Employer’s Tax Guide That classification matters because supplemental wages carry the same employer-side payroll taxes as regular wages. Two obligations run in parallel each time a bonus goes out: the employer withholds the employee’s income and payroll taxes from the check, and the employer pays its own matching taxes separately. Withholding is money the business holds temporarily on the worker’s behalf. The employer’s share is an independent cost that never appears on the pay stub.
Under IRC §3111, employers owe 6.2% of wages for Social Security and 1.45% for Medicare.2Office of the Law Revision Counsel. 26 USC 3111 – Rate of Tax Those rates are fixed by statute and apply to the gross bonus before any employee deductions. A $5,000 bonus means the employer owes an additional $310 in Social Security tax and $72.50 in Medicare tax from its own funds.
When the Social Security Cost Stops
The 6.2% Social Security obligation has a ceiling. For 2026, Social Security tax applies only to the first $184,500 in total wages per employee.3Social Security Administration. Contribution and Benefit Base Once someone’s combined salary and bonuses cross that threshold, neither the employer nor the employee owes additional Social Security tax for the rest of the year. This matters most for year-end bonuses to higher earners. If someone already earned $184,500 in regular pay by December, a holiday bonus carries zero Social Security cost.
Medicare has no cap. The 1.45% employer Medicare tax applies to every dollar of every bonus, regardless of how much the employee has already earned.4Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates There is also a 0.9% Additional Medicare Tax that applies to employees earning above $200,000, but employers do not match that surcharge. The only employer duty there is to withhold it from the employee’s pay once the threshold is crossed.
Unemployment Taxes You Also Owe
Employers fund unemployment insurance through two channels, both paid entirely by the employer. Employees never see a deduction for either one.
The Federal Unemployment Tax Act charges 6.0% on the first $7,000 of wages paid to each employee per year.5Employment and Training Administration. Unemployment Insurance Tax Topic Most employers receive a credit of up to 5.4% for paying state unemployment taxes on time, which drops the effective federal rate to 0.6%, or a maximum of $42 per employee per year.6Internal Revenue Service. Federal Unemployment Tax Because the $7,000 cap is so low, most employees hit it through regular wages early in the year, and bonuses paid later carry no additional FUTA cost.
State unemployment taxes follow a similar structure but vary widely. Taxable wage bases range from $7,000 to over $60,000 depending on the state, and employer rates differ based on the company’s history of former employees filing claims. A bonus paid before an employee reaches the state wage cap will be subject to state unemployment tax. Businesses operating in multiple states track each jurisdiction’s rules separately.
Gift Cards and Other Non-Cash Bonuses
Employer payroll taxes are not limited to cash. If you give an employee merchandise, a trip, or stock as a bonus, the fair market value counts as taxable wages, and the employer owes Social Security, Medicare, and FUTA on that value just as it would on a cash payment.7Internal Revenue Service. Publication 15-B, Employer’s Tax Guide to Fringe Benefits
Gift cards are the single most common trap. Many employers assume a $50 gift card is small enough to ignore, but the IRS is explicit: cash and cash equivalents like gift cards are never treated as de minimis fringe benefits, no matter how small the amount.8U.S. Government Publishing Office. 26 CFR 1.132-6 – De Minimis Fringe Benefits A $25 gift card to a coffee shop is taxable wages. True de minimis benefits are things like occasional office snacks or company-logo t-shirts, where tracking individual value would be impractical.
Deducting the Bonus and Its Payroll Taxes
The upside is that bonuses and the payroll taxes they generate are generally deductible. Under IRC §162(a), businesses can deduct reasonable compensation for services actually performed, which includes bonuses.9Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses The employer’s share of FICA and FUTA paid on those bonuses is also deductible as an ordinary business expense. The word “reasonable” carries weight. A bonus grossly disproportionate to the work performed, especially one paid to a shareholder-employee in a closely held company, can be reclassified by the IRS and partially disallowed.
Timing matters if you use accrual-basis accounting. A bonus accrued by December 31 is deductible on that year’s return only if the bonus is actually paid to the employee by March 15 of the following year. This 2.5-month window comes from Treasury regulations governing deferred compensation.10eCFR. 26 CFR 1.404(b)-1T – Deduction for Contributions of an Employer Miss that deadline by a day and the deduction shifts to the year the bonus is actually paid. Cash-basis businesses don’t face this issue since they deduct compensation in the year it goes out the door.
Depositing and Reporting the Tax
Employers report Social Security and Medicare obligations, including the employer’s matching share, on Form 941 each quarter.11Internal Revenue Service. About Form 941, Employer’s Quarterly Federal Tax Return FUTA is reported separately on Form 940, filed once a year.12Internal Revenue Service. About Form 940, Employer’s Annual Federal Unemployment (FUTA) Tax Return But reporting and depositing run on different timelines. Employment tax deposits follow either a monthly or semiweekly schedule, and every deposit goes through the Electronic Federal Tax Payment System.
Which schedule applies depends on a lookback period. If total employment tax liability was $50,000 or less during that period, deposits are monthly; above $50,000, they shift to semiweekly. New businesses default to monthly.13Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide There is also a next-day rule: if you accumulate $100,000 or more in tax liability on any single day, the deposit is due by the next business day.14Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements A large round of bonuses paid on the same date can easily trigger that threshold.
Keep all payroll tax records, including bonus calculations and deposit confirmations, for at least four years after the tax is due or paid, whichever comes later.15Internal Revenue Service. Employment Tax Recordkeeping
Penalties for Getting It Wrong
Late deposits trigger penalties under IRC §6656 based on how many calendar days the payment is overdue. A deposit that’s one to five days late incurs a 2% penalty on the unpaid amount, with the rate climbing as the delay grows.16Internal Revenue Service. Failure to Deposit Penalty These apply per deposit, so a company that habitually pays a few days late on quarterly filings can rack up charges quickly.
Late filing carries a separate penalty of 5% of the unpaid tax per month, capping at 25%. Late payment of the tax shown on a filed return adds 0.5% per month, also capping at 25%.17Office of the Law Revision Counsel. 26 U.S. Code 6651 – Failure to File Tax Return or to Pay Tax These can run simultaneously.
The most severe consequence is personal. Under the trust fund recovery penalty, any person responsible for collecting and paying over employment taxes who willfully fails to do so can be held personally liable for the full amount of the unpaid tax.18Office of the Law Revision Counsel. 26 USC 6672 – Failure to Collect and Pay Over Tax That typically means business owners, CFOs, or anyone with authority over payroll. The IRS can pursue the individual’s personal assets even if the business itself is insolvent.
If You’re Self-Employed or an S-Corp Owner
Sole proprietors and partners cannot pay themselves a bonus the way a corporation pays an employee. Draws from a sole proprietorship or partnership aren’t wages, so there is no employer-side FICA calculation. Self-employed individuals pay self-employment tax on their net business earnings at a combined 15.3%, covering both the employer and employee shares of Social Security and Medicare.19Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The same $184,500 Social Security cap applies to the 12.4% portion, and the 2.9% Medicare portion has no ceiling.
S-corporation owners who work in the business occupy a middle ground. They must pay themselves a reasonable salary, which is subject to the normal employer-employee FICA split. Additional distributions beyond that salary are not subject to payroll taxes. The employer-side tax on an S-corp owner’s bonus follows the same rules as any other employee bonus, but only if the payment is properly classified as wages rather than a distribution.
