Payroll Taxes for Employers: FICA, FUTA, SUTA, Deposit Schedules, and the Trust Fund Penalty

When you hire your first employee, you become responsible for withholding and remitting payroll taxes on a strict schedule. Late deposits trigger penalties starting at 2%. And if you mishandle the withheld taxes, the trust fund penalty is 100% — assessed personally.

Key Takeaways

  • Employers pay 7.65% in FICA taxes per employee (6.2% Social Security + 1.45% Medicare) — matching the same amount withheld from the employee's paycheck. Total FICA cost per employee: 15.3%.
  • Payroll tax deposits must follow strict schedules: monthly (for smaller employers) or semi-weekly (for employers who deposited over $50,000 in the prior lookback period). Deposits go to the IRS, not with the return.
  • FUTA (federal unemployment tax) is 0.6% on the first $7,000 of each employee's wages after the state credit. SUTA (state unemployment) varies by state and is separate.
  • The trust fund penalty is the most dangerous provision in payroll tax law: if you withhold employee payroll taxes and don't remit them, the IRS can assess 100% of the withheld amount personally against anyone responsible — even if the business later goes bankrupt.

The four main employer payroll taxes

Social Security (OASDI)6.2% employer + 6.2% employee$176,100 (2025)Employer and employee each pay 6.2%
Medicare1.45% employer + 1.45% employeeNo capEmployer and employee each pay 1.45%
Additional Medicare Tax0% employer + 0.9% employeeAbove $200k individual/$250k jointEmployee only; employer withholds
FUTA (federal unemployment)0.6% after state creditFirst $7,000 per employeeEmployer only — not withheld from wages
SUTA (state unemployment)Varies by state/employer historyVaries by stateEmployer only (most states)

The employer’s share of FICA is 7.65% of every dollar of wages — adding to the true cost of each employee beyond the W-2 salary. At $80,000 salary, the employer pays an additional $6,120 in FICA taxes.

The true cost of an employee

True employer cost — employee at $75,000 salary
Base salary$75,000
Employer Social Security (6.2% × $75,000)$4,650
Employer Medicare (1.45% × $75,000)$1,088
FUTA (0.6% × $7,000 first dollars)$42
SUTA — California UI (3.4% new employer × $7,000)$238
Workers' compensation insurance (estimate, varies by industry)$750–$3,000
Total payroll tax cost above salary$6,768–$9,018
True employer cost (salary + taxes, no benefits)$81,768–$84,018

FICA alone adds over $5,700 per employee per year — before FUTA, SUTA, or workers' comp. At 5 employees, that's $28,500+ in taxes on top of their salaries. This is why employee-to-contractor misclassification is financially tempting but legally dangerous.

Payroll tax deposit schedules

Withholding taxes (income tax withheld + employee + employer FICA) must be deposited with the IRS on a schedule — separate from when the payroll return is filed. Your schedule depends on how much payroll tax you deposited in your lookback period (the 12-month period ending June 30 of the prior year):

Depositor typeLookback period depositsDeposit deadline
New employerNo prior lookbackMonthly depositor for first year
Monthly depositor$50,000 or lessBy the 15th of the following month
Semi-weekly depositorMore than $50,000Wednesday payrolls → deposit by Friday; Friday payrolls → deposit by following Wednesday
Next-day depositor (large employers)Single payroll accumulation over $100,000Next business day — applies regardless of normal schedule

Deposits go to the IRS via EFTPS (Electronic Federal Tax Payment System). Checks and wire transfers are no longer accepted for most payroll tax deposits.

The deposit deadline is not the same as the return due date

Many first-time employers confuse the quarterly Form 941 due date with when taxes must be deposited. Form 941 is a reconciliation filed after the quarter. The actual taxes were due throughout the quarter via deposits. Filing Form 941 without having made timely deposits creates failure-to-deposit penalties on top of failure-to-file.

Failure-to-deposit penalties

The IRS failure-to-deposit penalty is tiered by how late the deposit is:

How latePenalty rate
1–5 days late2%
6–15 days late5%
More than 15 days late10%
Still not deposited 10 days after IRS notice15%

The trust fund penalty: the most dangerous provision

When you withhold income tax and the employee’s share of FICA from an employee’s paycheck, those funds are held in trustfor the federal government. They aren’t the business’s money — they’re taxes the employee already paid, temporarily sitting in your account.

The Trust Fund Recovery Penalty (IRC Section 6672) allows the IRS to assess 100% of the unpaid trust fund taxes personally against any person who was responsible for collecting and remitting these taxes and willfully failed to do so. This includes:

  • Business owners and officers
  • Accountants and bookkeepers with signatory authority
  • Anyone who had the authority to pay creditors but chose to pay other creditors instead of the IRS

The trust fund penalty survives bankruptcy

If the business goes bankrupt, its payroll tax liability may be discharged. The personal Trust Fund Recovery Penalty assessed against the owner is not. It follows you personally, cannot be discharged in bankruptcy, and continues to accrue interest. The IRS successfully uses this provision — it is not a theoretical risk.

FUTA and SUTA: unemployment taxes

Federal unemployment tax (FUTA) is paid by the employer only — it is never withheld from employees’ wages. The nominal rate is 6.0% on the first $7,000 of wages per employee, but businesses in states that are current on their FUTA loans receive a 5.4% credit — reducing the net federal rate to 0.6%.

FUTA deposits are due quarterly if the accumulated FUTA liability exceeds $500. Annual Form 940 (FUTA return) is due January 31.

State unemployment (SUTA) is separate — rate and wage base vary by state. California’s wage base for UI is $7,000 per employee in 2025; new employers pay 3.4% for the first two to three years before the rate adjusts based on claims experience.

Use a payroll service — the compliance burden is real

Payroll tax law has over a dozen deadlines, multiple tax rates with annual adjustments, and a penalty structure that punishes small mistakes significantly. Gusto, Rippling, or ADP for small business typically cost $40–$100/month and handle deposits, returns, W-2s, and state filings automatically. The time saved and penalty risk eliminated almost always exceeds the cost.

Frequently asked

Questions owners actually ask

Do I also owe payroll taxes on my own S-corp W-2 salary?
Yes — the same FICA rules apply to your own W-2 wages as an S-corp shareholder-employee. The corporation pays 7.65% as the employer share, and the remaining 7.65% is withheld from your paycheck. This is the FICA cost that gets avoided on distributions — which is why the salary/distribution split matters.
How do I know if I'm on monthly or semi-weekly deposit schedule?
Your deposit schedule is determined each January based on your 'lookback period' — the four quarters ending June 30 of the prior year. If your total payroll tax deposits during the lookback period were $50,000 or less, you're a monthly depositor. Over $50,000, you're semi-weekly. New employers are automatically monthly depositors for their first year.
What if payroll causes a cash flow problem — can I delay the deposit?
No — this is one of the most dangerous mistakes in small business finance. Payroll taxes are held in trust for the IRS; the money doesn't belong to the business. Using payroll tax deposits to cover operating expenses is how the trust fund penalty gets triggered. The IRS takes this extraordinarily seriously. If you're having cash flow problems, talk to a CPA before payroll day — not after.
What is Form 941 and when is it due?
Form 941 is the Employer's Quarterly Federal Tax Return. It reports total wages paid, income tax withheld, and Social Security/Medicare taxes for the quarter. It's due April 30, July 31, October 31, and January 31 (for Q1, Q2, Q3, and Q4 respectively). Form 941 is a reconciliation report — the actual tax was due earlier through deposits. Filing a 941 without having made deposits creates a failure-to-deposit penalty.
When are W-2s and W-3s due?
W-2s (to employees) and W-3 (transmittal to Social Security Administration) are due January 31 — the same deadline as 1099-NEC. E-filing is required if you have 10 or more W-2s. Payroll services like Gusto, ADP, or Paychex handle W-2 distribution and filing automatically.
What is SUTA and how much do I owe?
SUTA (State Unemployment Tax Act) is state-level unemployment insurance tax paid by the employer. The rate varies by state, by industry, and by your claim history (employers with more unemployment claims pay higher rates). New employers typically start at a 'standard' rate, which adjusts over time. California's SUTA is called UI (Unemployment Insurance) and is filed through EDD.
