Payroll Taxes 101: Understanding FICA, FUTA, and SUTA
Hiring your first employee? The 'Wage' is just the beginning. The hidden 10-15% cost of payroll taxes explained.
When you offer someone $100,000, it costs you ~$110,000. And they only take home ~$75,000. The “Wedge” in the middle is payroll tax. Understanding FICA --- the combined Social Security and Medicare taxes --- is the first step to managing this cost.
Key Takeaways
- Social Security: 6.2% (Employer) + 6.2% (Employee). Capped at $183,000 wages (2026 est.).
- Medicare: 1.45% (Employer) + 1.45% (Employee). Uncapped.
- FUTA (Federal Unemployment): 0.6% on the first $7,000. (Tiny).
- SUTA (State Unemployment): Varies wildly (1% - 10%) based on your 'Experience Rating' (layoffs).
- Employer Cost: Budget 1.08x to 1.10x of the gross salary.
The Deposit Schedule Danger
The IRS does not play around with “Trust Fund Taxes” (money withheld from employees). If you use that money to pay rent instead of sending it to the IRS?
- 100% Penalty.
- Personal Liability (Pierces the Corporate Veil).
- Potential Jail time. Advice: Use a payroll provider (Gusto, ADP). Never try to do payroll manually. The risk is infinite.
The Self-Employment Connection
If you are a sole proprietor or single-member LLC, you don’t have “payroll” — but you still pay the same taxes. The self-employment tax is the combined employer + employee share: 15.3% on net earnings (12.4% Social Security + 2.9% Medicare). This is why many business owners eventually elect S-Corp status and pay themselves a reasonable salary — to reduce the SE tax hit.
Payroll Tax and Estimated Payments
As an employer, payroll taxes are deposited on a schedule (semi-weekly or monthly depending on size). But as a business owner, don’t forget your own income tax. Your quarterly estimated tax payments cover your personal income tax and any pass-through business income — payroll deposits only cover FICA and unemployment.
