Payroll liabilities are the amounts your business owes to third parties the instant you run payroll: federal and state income taxes withheld from employees, the employee and employer shares of Social Security and Medicare, federal and state unemployment taxes, and any voluntary or court-ordered deductions like 401(k) contributions, health premiums, or garnishments. The money may sit in your bank account, but it is not yours. You are holding it in trust for the IRS, a state agency, or a benefits provider, and you have a fixed deadline to send it on. For 2026, the combined employer-employee Social Security and Medicare tax alone runs 15.3% of wages up to the $184,500 Social Security wage base, so even a small operation can accumulate thousands of dollars in payroll liabilities each pay period.1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
What Counts as a Payroll Liability
Every dollar withheld from an employee’s paycheck and every employer-side tax triggered by that paycheck is a payroll liability from the moment payroll runs until you remit the funds. The liability clears when the payment goes out.
A payroll liability is not the same as a payroll expense. The expense is the full cost of employing someone — gross wages plus your share of taxes and benefits. The liability is the narrower slice of that cost you still owe to a third party at any given moment.
What You Withhold From Employees
Most payroll liabilities begin as deductions from an employee’s gross pay. You collect these amounts and hold them until the deposit deadline.
- Federal income tax, in the amount determined by the employee’s Form W-4 (filing status, dependents, additional withholding requests).2Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate
- State and, in some places, local income tax. Each jurisdiction is a separate liability.
- Social Security tax at 6.2% of gross wages, up to the $184,500 wage base for 2026.1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
- Medicare tax at 1.45% of all gross wages, no cap.1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
- Additional Medicare Tax at 0.9% on wages above $200,000 in a calendar year. You must start withholding it once the employee crosses that threshold, regardless of their filing status.3Internal Revenue Service. Topic No. 560, Additional Medicare Tax
- Voluntary and court-ordered deductions: 401(k) contributions, health insurance premiums, wage garnishments, and child support orders. Each has its own recipient and its own remittance schedule.
Social Security and Medicare withholdings together are known as FICA. The employee’s FICA share totals 7.65% of wages up to the Social Security cap and 1.45% above it, plus the 0.9% Additional Medicare Tax past $200,000.1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
What the Employer Owes on Top
Beyond the amounts you withhold from employees, your business owes a second layer of payroll taxes out of its own pocket. These never appear on a pay stub, but they become liabilities the moment payroll runs.
FICA Employer Match
You match the employee’s Social Security and Medicare contributions dollar for dollar: 6.2% for Social Security up to $184,500 and 1.45% for Medicare on all wages.1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates There is no employer match on the Additional Medicare Tax; the 0.9% is the employee’s burden alone.3Internal Revenue Service. Topic No. 560, Additional Medicare Tax
Federal Unemployment Tax (FUTA)
FUTA is 6.0% on the first $7,000 of each employee’s annual wages. Employers who pay their state unemployment tax on time can claim a credit of up to 5.4%, bringing the effective FUTA rate to 0.6% — a maximum of $42 per employee per year.4Internal Revenue Service. Topic No. 759, Form 940, Employers Annual Federal Unemployment (FUTA) Tax Return – Filing and Deposit Requirements
State Unemployment Tax (SUTA)
Every state runs its own unemployment insurance program funded by employer payroll taxes. Rates vary based on your industry, claims history, and the state’s own formula, and taxable wage bases run anywhere from $7,000 to over $60,000. SUTA can be a rounding error in one state and a real cost in another.
State Paid Family and Medical Leave
A growing number of states fund paid family and medical leave through payroll taxes. Some split the cost between employer and employee; others put it entirely on the employee. Rates generally run between about 0.3% and 1.3% of wages. Whatever portion you withhold or owe becomes another liability to track and remit.
2026 Rates and Wage Bases
The dollar amounts change each year because the Social Security wage base is indexed to inflation. The 2026 numbers:
- Social Security: 6.2% employee, 6.2% employer, on wages up to $184,500. Maximum employee contribution: $11,439.1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
- Medicare: 1.45% employee, 1.45% employer, no wage cap.1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
- Additional Medicare Tax: 0.9% on employee wages over $200,000, no employer match.3Internal Revenue Service. Topic No. 560, Additional Medicare Tax
- FUTA: 6.0% on the first $7,000 per employee, reduced to an effective 0.6% with the full state credit.4Internal Revenue Service. Topic No. 759, Form 940, Employers Annual Federal Unemployment (FUTA) Tax Return – Filing and Deposit Requirements
When You Have to Deposit
The IRS puts every employer on either a monthly or semi-weekly deposit schedule for federal employment taxes (income tax withholding plus both halves of FICA). Your schedule depends on how much tax you reported during a lookback period.5Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements
- Monthly depositors reported $50,000 or less during the lookback period and deposit each month’s taxes by the 15th of the following month.5Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements
- Semi-weekly depositors reported more than $50,000. For wages paid Wednesday through Friday, the deposit is due the following Wednesday. For wages paid Saturday through Tuesday, the deposit is due the following Friday.6Internal Revenue Service. Notice 931, Deposit Requirements for Employment Taxes
- New employers with no lookback history default to the monthly schedule.5Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements
A next-day rule overrides both schedules. If your accumulated tax liability reaches $100,000 or more on any single day, you must deposit that amount by the close of the next business day.7eCFR. 26 CFR 31.6302-1 – Deposit Rules for Taxes Under the Federal Insurance Contributions Act Hitting that threshold once also moves you to semi-weekly status for the rest of the calendar year and the following year.
What You Have to File
Depositing the money is only half the obligation. You also file returns that reconcile what you withheld and what you sent.
Form 941 is the quarterly return most employers use to report wages paid, federal income tax withheld, and both shares of FICA. It is due by the last day of the month after each quarter ends: April 30, July 31, October 31, and January 31. If you deposited all taxes on time, you get an extra 10 days to file.8Internal Revenue Service. Topic No. 758, Form 941, Employers Quarterly Federal Tax Return and Form 944, Employers Annual Federal Tax Return
Form 944 is an annual alternative for very small employers with $1,000 or less in expected annual employment tax liability. You cannot self-elect it; the IRS must notify you in writing that you qualify.9Internal Revenue Service. Certain Taxpayers May File Their Employment Taxes Annually
Form 940 is the annual FUTA return. It reconciles the federal unemployment tax you owe for the year, accounts for the state credit, and settles any balance due.10Internal Revenue Service. About Form 940, Employers Annual Federal Unemployment Tax Return
Form W-2 goes to each employee by January 31, summarizing annual wages, federal and state taxes withheld, and FICA. The same forms must be filed with the Social Security Administration by that date.11Social Security Administration. Deadline Dates to File W-2s
Penalties for Missing a Deposit
Miss a deposit deadline and the penalty is automatic. The IRS calculates it as a percentage of the unpaid amount, and it escalates fast:12Internal Revenue Service. 20.1.4 Failure to Deposit Penalty
- 1 to 5 days late: 2% of the undeposited tax
- 6 to 15 days late: 5%
- More than 15 days late: 10%
- Still unpaid 10 days after the IRS’s first notice demanding payment: 15%
Interest accrues on top of those penalties. Depositing by the wrong method, such as paying by paper check when electronic funds transfer is required, can also land you in the 10% tier.12Internal Revenue Service. 20.1.4 Failure to Deposit Penalty
Why Payroll Taxes Are Personal
Federal income tax and the employee’s share of FICA are “trust fund” taxes, because the employer is holding money that legally belongs to the government. If a business fails to turn those funds over, the IRS can pursue the individuals responsible rather than the company alone. This is the trust fund recovery penalty under 26 U.S.C. § 6672, and it equals the full amount of the unpaid tax.13Office of the Law Revision Counsel. 26 USC 6672 – Failure to Collect and Pay Over Tax, or Attempt to Evade or Defeat Tax
The penalty reaches any person who had authority to make sure the taxes were paid and willfully failed to do so. In practice, that can extend beyond the owner to a controller, a bookkeeper, or anyone else with check-signing authority or control over company accounts. Delegating payroll to someone else does not shield you if you retained the power to direct payments.
This is where payroll liabilities part company with almost every other business debt. Unpaid vendor bills are the company’s problem. Unpaid trust fund taxes become a personal problem. The IRS must notify you in writing at least 60 days before assessing the penalty, but once it sticks, it survives bankruptcy and cannot be discharged.13Office of the Law Revision Counsel. 26 USC 6672 – Failure to Collect and Pay Over Tax, or Attempt to Evade or Defeat Tax If cash is tight and you are choosing which bills to pay first, payroll taxes belong at the top of the list.
