Payroll taxes are the most dangerous tax obligation a small business can have, because the penalties for noncompliance are severe, personal, and cannot be discharged in bankruptcy. When an employer withholds income tax and FICA from an employee’s paycheck, those funds are held in trust for the government under IRC 7501. If the employer fails to deposit those funds, the trust fund recovery penalty under IRC 6672 imposes personal liability on any “responsible person” (owner, officer, bookkeeper, or anyone with authority over the company’s finances) for 100% of the unpaid trust fund taxes. The IRS considers payroll tax compliance a top priority, and automated processes flag late deposits quickly. The employer’s total payroll tax burden is approximately 7.65% of wages (employer’s share of FICA), plus FUTA, plus the cost of timely deposits, quarterly returns, and annual W-2 filing.

What are the costs and risks of payroll taxes?

Hypothetical example

Round numbers. A small business has 5 employees with the following annual compensation.

Payroll details:

Employee	Annual Salary	Pay Frequency
Manager	$80,000	Bi-weekly
Sales Rep	$60,000	Bi-weekly
Admin	$45,000	Bi-weekly
Technician 1	$50,000	Bi-weekly
Technician 2	$50,000	Bi-weekly
Total payroll	$285,000

Employer’s payroll tax cost:

Tax	Calculation	Annual Cost
Employer Social Security (6.2%)	$285,000 x 6.2%	$17,670
Employer Medicare (1.45%)	$285,000 x 1.45%	$4,133
FUTA (0.6% after state credit, first $7,000)	5 employees x $7,000 x 0.6%	$210
State unemployment (SUI, estimated 2.5% on first $7,000-$40,000 depending on state)	Varies; assume $1,500	$1,500
Workers’ compensation insurance (varies by industry)	Assume $3,000	$3,000
Total employer payroll tax cost		$26,513
As percentage of total payroll		9.3%

Employee withholding (employer must withhold and deposit):

Tax	Calculation	Annual Withholding
Employee Social Security (6.2%)	$285,000 x 6.2%	$17,670
Employee Medicare (1.45%)	$285,000 x 1.45%	$4,133
Federal income tax (estimated average 15% effective)	$285,000 x 15%	$42,750
State income tax (varies)	Assume $10,000	$10,000
Total withheld from employees		$74,553

Total payroll tax deposits (employer + employee share):

Component	Amount
Employer FICA (SS + Medicare)	$21,803
Employee FICA (SS + Medicare)	$21,803
Federal income tax withheld	$42,750
Total federal deposits	$86,356
Per pay period (bi-weekly, 26 periods)	$3,321

Penalties for late deposits:

Days Late	Penalty Rate
1-5 days	2% of undeposited amount
6-15 days	5%
16+ days	10%
10+ days after first IRS notice	15%

Example: $10,000 deposit is 10 days late: | Penalty | $10,000 x 5% = $500 |

Trust Fund Recovery Penalty (IRC 6672):

Element	Details
What it covers	Employee’s share of FICA + withheld federal income tax (the “trust fund” portion)
Amount	100% of the unpaid trust fund taxes
Who is liable	Any “responsible person” (owner, officer, director, bookkeeper, or any person with authority to pay) who “willfully” fails to pay
”Willful”	Does not require evil intent; paying other creditors instead of the IRS is “willful”
Personal liability	Cannot be avoided through the corporate shield; applies to individuals personally
Bankruptcy	Cannot be discharged in bankruptcy
Multiple liable persons	Each responsible person is liable for the full amount; IRS can collect from any or all

Example of the trust fund recovery penalty:

Unpaid payroll taxes (one quarter)	Amount
Employee FICA (SS + Medicare)	$5,451
Federal income tax withheld	$10,688
Trust fund portion	$16,139
Employer FICA (not trust fund)	$5,451
TFRP assessed against owner personally	$16,139

If the business owes 4 quarters of unpaid payroll taxes, the TFRP is $64,556 assessed personally against the owner (or any responsible person), on top of the business’s liability for the employer share.

Common payroll tax mistakes:

Mistake	Consequence
Misclassifying employees as independent contractors	Back payroll taxes + penalties + IRC 3509 reduced rates (if unintentional)
Depositing late	2-15% penalty + interest
Not filing Form 941 on time	5% per month penalty (up to 25%)
Paying other creditors before IRS	”Willful” failure; TFRP assessed personally
Not withholding Additional Medicare Tax (0.9%) on wages over $200,000	Employer liable for the under-withholding
Incorrect W-2s	Penalties: $60-$310 per W-2 depending on when corrected
Not filing W-2s electronically (250+ forms)	$310 per W-2 penalty

Payroll tax calendar:

Date	Action
Each pay period	Calculate and withhold federal income tax, FICA from employee wages
Semi-weekly or monthly	Deposit payroll taxes (EFTPS)
January 31	File Form 940 (FUTA); file Forms W-2 and W-3
April 30	File Form 941 (Q1)
July 31	File Form 941 (Q2)
October 31	File Form 941 (Q3)
January 31	File Form 941 (Q4)

Payroll for S-Corp owners:

Rule	Details
S-Corp shareholder-employees must take reasonable compensation	Subject to all employment taxes
Distributions are not subject to FICA	But salary must be reasonable (see reasonable compensation guide)
Health insurance premiums (>2% shareholder)	Included in W-2 wages (Box 1) but excluded from FICA (Boxes 3 and 5)
Retirement plan contributions	Employer contributions are deductible; employee deferrals reduce Box 1 wages

What are the penalties for late payroll tax deposits?

The IRS imposes graduated penalties for late payroll tax deposits: 2% if 1-5 days late, 5% if 6-15 days late, 10% if more than 15 days late, and 15% if still unpaid 10 days after the first IRS notice. These percentages apply to the unpaid deposit amount. The trust fund recovery penalty (IRC 6672) can hold owners, officers, and even bookkeepers personally liable for the employee’s share of unpaid payroll taxes, piercing the corporate veil entirely. This is one of the few tax penalties that cannot be discharged in bankruptcy.

How do I determine my payroll deposit schedule?

The IRS assigns businesses to either a monthly or semi-weekly deposit schedule based on the lookback period (the four quarters ending June 30 of the prior year). If total employment taxes during the lookback period were $50,000 or less, deposits are due monthly (by the 15th of the following month). Above $50,000, deposits follow a semi-weekly schedule (Wednesday/Friday based on payday). New businesses default to monthly. The schedule resets each calendar year. Regardless of schedule, accumulating $100,000 or more in undeposited taxes on any day triggers a next-business-day deposit requirement.

What payroll tax deposits are required and when are they due?

Federal payroll tax deposits include withheld income tax plus both the employee and employer shares of FICA (Social Security and Medicare), and the deposit schedule depends on your total tax liability. Monthly depositors must deposit employment taxes by the 15th of the following month, while semi-weekly depositors must deposit by Wednesday for Saturday-Tuesday paydays and by Friday for Wednesday-Friday paydays. The IRS assigns your deposit schedule based on your lookback period liability (the four quarters ending June 30 of the prior year): $50,000 or less means monthly, over $50,000 means semi-weekly. The $100,000 next-day deposit rule applies regardless of your regular schedule. If you accumulate $100,000 or more in employment taxes on any day, you must deposit by the next business day and switch to semi-weekly status for the remainder of the year and the following year.
