Trust Fund Tax Warning:
Employee payroll taxes (the amounts withheld from employee paychecks for federal income tax, Social Security, and Medicare) are NOT your money. They are collected "in trust" for the IRS. Failing to deposit them on time can trigger the Trust Fund Recovery Penalty — a 100% personal liability penalty assessed against any "responsible person" (owner, officer, bookkeeper) who willfully failed to deposit. This is one of the few business liabilities that pierces the LLC/corporate veil. Payroll taxes must always be deposited on schedule.
Payroll Taxes: What Employers Pay in 2026
Social Security Tax (FICA)
12.4%
Split: 6.2% employer + 6.2% employee
Applies to wages up to the Social Security wage base ($176,100 in 2026). Wages above the wage base are exempt. Both employer and employee each pay 6.2%. Total combined: 12.4%.
Medicare Tax (FICA)
2.9%
Split: 1.45% employer + 1.45% employee
No wage base cap — applies to all wages. Additional 0.9% surtax applies to employee wages above $200,000 ($250,000 for joint filers) — withheld from employee only, not matched by employer.
Federal Unemployment (FUTA)
6.0%
Employer only (employees don't pay FUTA)
Applies to first $7,000 of each employee's wages. Credit of up to 5.4% for state unemployment taxes paid on time — effective FUTA rate can be as low as 0.6% = $42/employee/year.
State Unemployment (SUI)
Varies
Employer only (most states)
Rate varies by state (typically 1–8%) and experience rating (your claims history). Wage base varies: $7,000–$40,000+ depending on state. New employer rate is typically 2–3% until claims history establishes your rate.
Federal Income Tax Withholding
Varies
Withheld from employee; employer deposits
Withheld from employee wages based on W-4 elections (filing status, adjustments, additional withholding). Employer collects and deposits — does not match. Employee owes the tax; employer is the collection agent.
State Income Tax Withholding
Varies
Withheld from employee; employer deposits
Same mechanics as federal income tax withholding. Rate and wage base vary by state. Nine states have no state income tax: AK, FL, NV, NH (wages), SD, TN, TX, WA, WY.
Payroll Tax Calculation Example
Here's how payroll costs break down for a single employee earning $24/hour, 40 hours/week ($1,000/week gross, ~$52,000/year):
Employee Gross Pay: $1,000.00 / week | Annual: $52,000
Gross Wages$1,000.00
Federal Income Tax Withheld (est., single/standard)−$90.00
Employee Social Security (6.2%)−$62.00
Employee Medicare (1.45%)−$14.50
State Income Tax Withheld (est. 4%)−$40.00
Employee Net Take-Home Pay$793.50
Employer Social Security Match (6.2%)$62.00
Employer Medicare Match (1.45%)$14.50
FUTA (6% on $7K base, credit to 0.6% effective)$0.81/week (capped)
SUI (est. 2.5% on $7K base)$3.37/week (capped)
Total Additional Employer Taxes/week~$80.68
Total Cost to Employer / Week~$1,080.68
A $52,000/year employee costs the employer approximately $56,000–$57,000 in employment taxes alone — before benefits, workers' comp, or other costs.
Payroll Tax Deposit Schedule
| Schedule | Who It Applies To | Deposit Deadline | Applies To |
|---|---|---|---|
| Monthly Depositor | Businesses that owed $50,000 or less in employment taxes during the 4-quarter lookback period. Most new employers start here. | 15th of the following month | Federal income tax withheld + employee and employer FICA |
| Semi-weekly Depositor | Businesses that owed more than $50,000 during the lookback period. | Wednesday payday → deposit by Wednesday. Thursday–Saturday payday → deposit by following Wednesday. | Federal income tax withheld + employee and employer FICA |
| Next-Day Depositor (Special Rule) | ANY employer that accumulates $100,000 or more in payroll taxes on any single day. | Next business day — regardless of normal schedule | Federal income tax withheld + employee and employer FICA |
| FUTA (Form 940) | All employers with FUTA liability exceeding $500 in any quarter | Last day of the month following the quarter (Apr 30, Jul 31, Oct 31, Jan 31) | Federal unemployment tax (FUTA) |

Plus the SSA/IRS W-2 and W-3 filing deadline: January 31 (same as employee W-2 deadline). The 1096 summary for 1099s is also due January 31 if filing on paper (March 31 if e-filing).
W-2 Employees vs. 1099 Independent Contractors
This is one of the most consequential decisions in small business HR. Misclassifying employees as contractors is a top IRS audit trigger — penalties include back taxes, interest, and penalties on both employee and employer shares.
W-2 Employee
- Business controls what is done AND how it's done
- Works set hours, at business location, with business tools
- Ongoing, indefinite relationship
- Employer withholds and matches FICA
- Employer withholds federal and state income tax
- Employer pays FUTA and SUI
- Workers' comp required (most states)
- Must receive W-2 by January 31
- ACA health coverage may be required at 50+ FTE
1099 Independent Contractor
- Business controls what is done, NOT how
- Sets own hours, uses own tools, may work for others
- Project-based or time-limited relationship
- No employer FICA match — contractor pays self-employment tax (15.3%)
- No income tax withholding — contractor pays quarterly estimates
- No FUTA or SUI
- No workers' comp requirement (verify by state)
- Issue 1099-NEC if paid $600+ in a year
- No ACA requirements
The Misclassification Risk:
If the IRS reclassifies your 1099 contractors as employees: you owe back FICA (employee AND employer shares), back federal income tax withholding, FUTA, state unemployment, penalties, and interest — often going back 3 years. The IRS Section 530 safe harbor can provide relief in some cases, but the best protection is correct classification from the start. Use the IRS Form SS-8 to request a determination if you're uncertain, or consult an employment law attorney.
Payroll Forms Every Small Business Needs to Know
- Form W-4 — Employee's Withholding Certificate. New employees complete this so you know how much federal income tax to withhold. Current version revised 2020 and significantly different from earlier versions.
- Form I-9 — Employment Eligibility Verification (required within 3 business days of hire). Must verify identity and work authorization. Retain for 3 years after hire or 1 year after termination, whichever is later.
- Form 941 — Employer's Quarterly Federal Tax Return. Reports total wages, tips, federal income tax withheld, Social Security tax, and Medicare tax. Filed quarterly even if you deposit monthly.
- Form 940 — Employer's Annual Federal Unemployment (FUTA) Tax Return. Filed annually (January 31), with quarterly deposits when FUTA liability exceeds $500.
- Form W-2 — Wage and Tax Statement. Sent to each employee and to SSA/IRS by January 31. Reports total wages, all withholding.
- Form W-3 — Transmittal of Wage and Tax Statements. Summary of all W-2s sent to SSA. Due January 31 (same day as W-2s to SSA).
- Form 1099-NEC — Nonemployee Compensation. Required for each independent contractor paid $600+ in a year. Due January 31.

The Most Expensive Payroll Mistakes
- Missing a payroll tax deposit deadline. The IRS failure-to-deposit penalty: 2% for 1–5 days late, 5% for 6–15 days late, 10% for 16+ days late or notice issued. All on top of the taxes owed. On a $10,000 deposit, that's $1,000 just for being 16 days late.
- Misclassifying employees as independent contractors. Already discussed above — one of the highest-cost payroll errors. The IRS explicitly watches for businesses with all "contractors" and no employees in high-risk industries.
- Paying employees "off the books" or in cash without withholding. Cash compensation is still taxable income. Paying in cash doesn't exempt you from payroll tax obligations — it just makes it harder to track, and the IRS can reconstruct payroll from bank records and tips from employees.
- Using payroll tax deposits to cover a cash flow shortfall. Trust Fund Recovery Penalty. Enough said. If cash is short and you're facing a payroll tax deposit — call the IRS about an installment agreement before missing the deposit.
- Not keeping payroll records for 4 years. Employment tax records must be kept for 4 years from when the tax was due or paid. This includes W-4s, I-9s, payroll registers, and tax deposit records.
Payroll funding tip:
If payroll is growing faster than cash flow — a common issue for seasonal businesses and rapidly growing companies — a merchant cash advance can provide same-day or next-day working capital to cover payroll without missing a tax deposit deadline. T.A.G. has a specific payroll funding MCA option for businesses in this situation.
Frequently Asked Questions
- What payroll taxes does an employer pay?
- As an employer you pay: (1) Your 6.2% share of Social Security tax (up to the $176,100 wage base in 2026), (2) your 1.45% share of Medicare tax (no cap), (3) FUTA — 6.0% on the first $7,000 of each employee's wages, reduced to as low as 0.6% with the state unemployment tax credit, and (4) state unemployment tax (SUI) — rate and wage base vary by state. You also collect and deposit (but don't pay) federal and state income tax withheld from employee paychecks, plus the employee's share of FICA.
- When are payroll taxes due?
- Most new small businesses are monthly depositors — deposit by the 15th of the month following the payroll month. If you owed more than $50,000 in employment taxes during your lookback period, you become a semi-weekly depositor — deadlines depend on payday (Wednesday payday → deposit by Wednesday of the next week; Thursday–Saturday payday → deposit by the following Wednesday). If you accumulate $100,000 in any day, deposit the next business day — regardless of schedule. Quarterly Form 941 is due April 30, July 31, October 31, and January 31. W-2s and 1099-NECs to recipients are due January 31.
- What is the difference between a W-2 employee and a 1099 contractor?
- The IRS uses a three-category test: behavioral control (does the business direct how work is done, not just what?), financial control (does the business control payment method, reimbursement, and investment in tools?), and type of relationship (permanent ongoing relationship vs. project-based with written contract?). If the answer to most of these points toward control by the business, the person should be classified as an employee (W-2). Independent contractors set their own hours, use their own tools, can work for multiple clients, and are typically on project contracts. Misclassification is one of the top IRS enforcement priorities — when in doubt, W-2 is safer.
