Employment taxes that employers must withhold and report break into three federal buckets: income tax and the employee’s share of Social Security and Medicare come out of each paycheck, a matching Social Security and Medicare contribution plus federal unemployment tax come from the company’s own funds, and the totals get reconciled on quarterly and annual returns. The obligations begin the moment you hire your first employee, and the money you withhold is treated by the IRS as held in trust for the government from the second it leaves the paycheck.
What Gets Withheld from Each Paycheck
Three federal taxes come out of employee wages every pay period.
Federal income tax. The amount is calculated from the employee’s Form W-4, which supplies filing status and any adjustments for dependents or other income. The IRS publishes the withholding tables each year in Publication 15-T. For supplemental wages like bonuses and commissions, employers may apply a flat 22 percent rate instead of running the payment through the regular tables. Supplemental payments above $1 million in a calendar year are subject to a mandatory 37 percent rate.
Social Security tax. Withhold 6.2 percent of gross wages up to the annual wage base. For 2026, the cap is $184,500. Once an employee’s year-to-date earnings cross that threshold, no additional Social Security tax is withheld for the rest of the year.
Medicare tax. Withhold 1.45 percent on every dollar of wages. There is no cap. Once an employee’s wages exceed $200,000 in a calendar year, an Additional Medicare Tax of 0.9 percent applies to the excess. Employers must begin withholding the additional 0.9 percent in the pay period the $200,000 threshold is crossed, regardless of the employee’s filing status.
What the Employer Pays on Top of Wages
Withholding is only half the bill. Employers owe a matching contribution from company funds: 6.2 percent for Social Security up to the same $184,500 base, and 1.45 percent for Medicare on all wages. Combined, employer and employee FICA totals 15.3 percent of wages up to the Social Security cap and 2.9 percent above it. There is no employer match on the Additional Medicare Tax; that 0.9 percent falls on the employee alone.
Federal Unemployment Tax
FUTA is paid entirely by the employer. The statutory rate is 6.0 percent on the first $7,000 of wages paid to each employee during the calendar year. Employers who pay their state unemployment taxes on time receive a credit of up to 5.4 percent, which drops the effective rate to 0.6 percent, or a maximum of $42 per employee per year.
The 5.4 percent credit shrinks in credit reduction states, meaning states that borrowed from the federal government to pay unemployment benefits and failed to repay the loans on schedule. The reduction starts at 0.3 percent and grows by another 0.3 percent for each additional year the debt remains outstanding. In a state with a 0.3 percent reduction, effective FUTA is 0.9 percent instead of 0.6 percent. The IRS publishes the credit reduction list each November, and any extra liability is due by January 31 of the following year.
Depositing the Money
Federal employment tax deposits go through the Electronic Federal Tax Payment System, a free platform run by the U.S. Department of the Treasury. The IRS assigns each business a deposit schedule based on the total tax liability reported during a lookback period, which is the four consecutive quarters ending June 30 of the prior year. For 2026, that window runs from July 1, 2024, through June 30, 2025.
- Monthly depositors reported $50,000 or less in employment taxes during the lookback period. Deposits are due by the 15th of the month following the month wages were paid.
- Semiweekly depositors reported more than $50,000. Taxes on wages paid Wednesday through Friday are due the following Wednesday; taxes on wages paid Saturday through Tuesday are due the following Friday.
A separate rule sits above both schedules. If you accumulate $100,000 or more in employment tax liability on any single day, the full amount must be deposited by the next business day. Triggering the $100,000 rule also flips you to semiweekly for the rest of the calendar year and all of the following year.
Late-Deposit Penalties
The failure-to-deposit penalty escalates with the delay:
- 1 to 5 calendar days late: 2 percent of the unpaid deposit
- 6 to 15 calendar days late: 5 percent
- More than 15 calendar days late: 10 percent
- More than 10 days after the first IRS notice, or on receipt of a demand for immediate payment: 15 percent
The tiers don’t stack. A deposit 20 days late incurs the 10 percent penalty, not the sum of the lower ones.
Forms You File to Report It
Depositing the money doesn’t discharge the reporting obligation. Employers file separate returns that reconcile what was withheld and deposited against what was owed.
Form 941 (Quarterly)
Form 941 reports total wages paid, federal income tax withheld, and both shares of Social Security and Medicare tax for the quarter. It is due by the last day of the month following the end of the quarter: April 30, July 31, October 31, and January 31. Once you file your first Form 941, the IRS expects one every quarter after, even if you paid no wages.
Form 940 (Annual FUTA)
Form 940 reports federal unemployment tax for the full calendar year, tracks taxable wages up to the $7,000 FUTA base for each employee, and accounts for any credit reductions. The standard due date is January 31 of the following year. The deadline extends to February 10 if all FUTA was deposited on time throughout the year.
Forms W-2 and W-3 (Annual Wage Statements)
By January 31 following the end of the tax year, each employee must receive a Form W-2 showing total wages and all taxes withheld. Copies of every W-2, together with the transmittal Form W-3, must also be filed with the Social Security Administration by that same deadline. For 2026 wage reporting, the filing deadline is February 1, 2027, because January 31 falls on a Sunday.
Form 1099-NEC (Independent Contractors)
Contractors are not employees, so nothing is withheld from their pay. But if a business pays a contractor $2,000 or more during the tax year, it must report the total on Form 1099-NEC. The threshold rose from $600 for tax years beginning after 2025 and will be inflation-adjusted starting in 2027. The form is due to both the contractor and the IRS by January 31 of the following year, with no automatic filing extension available.
Getting the Employee-or-Contractor Line Right
Every obligation above rides on one prior question: is the worker an employee or an independent contractor? Employees trigger withholding, matching contributions, and unemployment tax. Independent contractors handle their own tax payments, and the business’s only federal reporting duty is the 1099-NEC. The IRS applies common law rules built around three categories of control.
- Behavioral control. Does the business direct how, when, and where the work gets done? Detailed instructions, required training, and set schedules point to an employment relationship.
- Financial control. Does the worker invest in their own tools, bear the risk of profit or loss, and offer services on the open market? Contractors typically operate like a separate business; employees receive a guaranteed wage.
- Relationship of the parties. Is the arrangement permanent or project-based? Are benefits provided? Written contracts matter, but the IRS looks at the actual working relationship, not just the paperwork.
No single factor decides it. The IRS weighs all the evidence together to determine whether the business has the right to control the details of how the work is done.
Fixing a Misclassification
Businesses that have been treating workers as contractors and realize the classification is wrong can apply for the IRS Voluntary Classification Settlement Program, which allows prospective reclassification with limited liability for past periods. Eligibility requires that the business consistently treated the workers as contractors, filed all required Forms 1099 for the prior three years, and is not currently under an employment tax audit by the IRS or the Department of Labor. If a prior audit already addressed the classification, the business must have complied with the results.
Paperwork Before the First Paycheck
Every business with employees needs an Employer Identification Number, the nine-digit number the IRS uses to track the company’s tax accounts. You can apply online for free at IRS.gov or submit Form SS-4 by fax or mail.
Before a new employee starts work, two forms have to be completed. Form W-4 tells the employer how to calculate federal income tax withholding based on the employee’s personal situation. Form I-9, administered by U.S. Citizenship and Immigration Services, verifies the employee’s identity and authorization to work in the United States: the employee completes Section 1, then presents acceptable identity and work authorization documents that the employer examines and records in Section 2.
Retention periods differ. Employment tax records, including wage payments, withholding amounts, and any credits claimed, must be kept for at least four years after the due date of the return or the date the tax was paid, whichever is later. Form I-9 must be retained for three years after the hire date or one year after the employment ends, whichever is later.
Personal Liability If You Fall Behind
Federal income tax and the employee’s share of FICA are considered trust fund taxes because the employer holds them in trust for the government. When a business fails to turn those funds over, the IRS can pursue the Trust Fund Recovery Penalty against any “responsible person” who willfully failed to pay.
A responsible person is anyone with the authority and control to decide which creditors get paid. That includes corporate officers, directors, shareholders with operational control, partners, and even bookkeepers or outside payroll providers who exercise independent judgment over company finances. An employee who merely cuts checks at a supervisor’s direction is not a responsible person. The IRS assesses responsibility based on actual authority, not job titles.
Willfulness does not require bad intent. If you knew the taxes were due and chose to pay rent, vendors, or other creditors first, that is enough. The penalty equals the full amount of trust fund taxes that went unpaid and attaches to individuals personally. Corporate bankruptcy does not erase it. Businesses that use outside payroll services sometimes assume the provider is responsible for deposit timing, but the employer remains liable. If a payroll company misses a deadline or misappropriates funds, the IRS still comes to the employer first.
State Obligations That Sit Alongside the Federal Rules
Federal employment taxes are only part of the picture. Every state imposes its own unemployment insurance tax on employers, commonly called SUTA. State rates vary widely and depend on the employer’s industry, years in operation, and layoff history. New employers are typically assigned a default rate until they build enough experience for the state to calculate an individual one. A handful of states also require employees to contribute a portion of their wages toward unemployment insurance.
State taxable wage bases also diverge from the $7,000 federal FUTA base. Some states match the federal floor; others tax wages well above it. Most states also require income tax withholding, with rates, brackets, and filing procedures that differ by state. Employers operating in multiple states have to track each state’s rules separately.
Federal law also requires every new hire to be reported to the state’s new-hire directory, generally within 20 days of the hire date. Some states set shorter deadlines. Multi-state employers that designate a single state for all new-hire reporting must submit electronically at least twice a month. These reports feed the national database used to enforce child support orders and detect improper benefit payments.
