Understanding Employer Payroll Taxes: The Full Guide

As an employer, you are required to pay payroll taxes on top of each employee's gross wages. These taxes fund Social Security, Medicare, and federal and state unemployment insurance programs. Unlike employee withholding — which is deducted from the worker's paycheck — employer payroll taxes are an additional cost that comes out of your business's pocket. For small businesses, understanding and budgeting for these taxes is essential to accurate financial planning and staying compliant with the IRS and state agencies.

Social Security Tax (OASDI) — Employer's Share

The employer pays 6.2% of each employee's wages toward Social Security, up to the annual wage base limit. In 2024, that limit is $168,600. Once an employee's year-to-date wages exceed this threshold, the employer stops paying Social Security tax on additional earnings. For an employee earning $75,000, the employer's Social Security contribution is $4,650 per year. For a high earner at $200,000, the maximum is capped at $10,453.20.

Medicare Tax — Employer's Share

Employers pay 1.45% of all employee wages toward Medicare with no income cap. Unlike Social Security, there is no ceiling — the 1.45% applies to every dollar earned. Employers do not pay the additional 0.9% Medicare surtax; that applies only to employees earning above $200,000 (single) or $250,000 (married filing jointly). For a $75,000 salary, the employer's Medicare tax is $1,087.50 annually.

Federal Unemployment Tax (FUTA)

FUTA funds the federal unemployment insurance system. The gross rate is 6.0% on the first $7,000 of each employee's wages per year. However, employers in states with compliant unemployment programs receive a 5.4% credit, reducing the effective FUTA rate to just 0.6%. That means the maximum annual FUTA tax per employee is only $42. While the per-employee cost is small, it adds up: 50 employees equals $2,100 per year in FUTA alone.

State Unemployment Tax (SUTA)

Every state runs its own unemployment insurance program funded by employer contributions. SUTA rates and wage bases vary dramatically by state. New employers are typically assigned a standard rate (often 2–4%), which adjusts over time based on the employer's "experience rating" — essentially, how many former employees have filed unemployment claims. Employers with low turnover and few claims earn lower rates, while those with high claims pay more.

The wage base — the amount of each employee's wages subject to SUTA — also varies widely. Some states tax only the first $7,000 (matching the federal base), while others tax up to $56,700 or more. This means the total SUTA cost per employee can range from under $100 to over $1,500 depending on your state and experience rating.

Budgeting for Employer Payroll Taxes

A reliable rule of thumb is to budget 7.65%–10% of gross payroll for employer-side payroll taxes. The 7.65% covers the combined FICA obligation (6.2% Social Security + 1.45% Medicare), while the remaining percentage accounts for FUTA and SUTA. For a team of five employees each earning $75,000, expect to pay roughly $30,000–$38,000 per year in employer payroll taxes alone — before you account for benefits like health insurance, workers' compensation, or retirement contributions.

• Small teams (1–10 employees): Payroll taxes are a significant line item. Accurate calculation prevents cash flow surprises.
• Growing teams: Each new hire adds not just salary but 8–10% in additional tax obligations. Factor this into headcount planning.
• Multi-state employers: SUTA rates and wage bases differ by state. If you have remote employees in multiple states, you may owe SUTA in each state.

Payroll Tax Compliance Tips

• Deposit on time: Federal payroll tax deposits are due monthly or semi-weekly depending on your total tax liability. Late deposits trigger penalties starting at 2% and escalating to 15%.
• File quarterly returns: Form 941 (federal) is due by the last day of the month following each quarter. State UI reports have separate deadlines.
• Track the SS wage base: Stop withholding Social Security once an employee hits the annual cap. Overpayment creates refund obligations.
• Monitor your SUTA rate: Review your experience rating annually. A rising rate may signal a turnover problem that's also costing you in taxes.
• Use payroll software when it makes sense: Manual payroll tax calculations are error-prone. Payroll software or a payroll provider can calculate taxes, make deposits and file returns for you.

Payroll taxes are one of those costs that every employer pays but few fully understand. Using an employer payroll tax calculator gives you clarity on the true cost of each hire and helps you budget accurately as your team grows. Tiny Team doesn't run payroll or file taxes, but its HR module keeps each person's compensation history and bank details for reference, under role-based access.

How to Run Payroll Manually in 5 Steps

Running payroll means calculating each employee's wages, withholding the correct taxes, paying people on a consistent schedule, and then depositing and reporting those taxes. The calculator above covers the employer's share of payroll taxes. The steps below cover the whole pay run for a small business doing it by hand.

What You Need Before Running Payroll

Get these registrations in place before you process a single paycheck. Missing even one can delay your payroll setup by weeks.

From each employee, collect a Form W-4 (federal income tax withholding), a Form I-9 (employment eligibility), your state's withholding form if it has an income tax, a direct deposit authorization with their bank routing and account numbers, and their full legal name, Social Security number, address and date of birth.

Step 1: Choose a Pay Schedule

Weekly pay (52 paychecks a year) suits hourly workers in construction or restaurants. Biweekly (26) is the most common choice for small businesses, according to the Bureau of Labor Statistics. Semi-monthly (24, usually the 1st and 15th) suits salaried employees, and monthly (12) works for very small companies. Some states set a minimum pay frequency; California, for example, requires semi-monthly or more frequent pay for most employees, so check your state's rules before you commit to a schedule.

Step 2: Calculate Gross Pay

Gross pay is what an employee earns before any deductions. For hourly employees, multiply hours worked by the hourly rate, and pay any hours over 40 in a workweek at 1.5 times the regular rate, as the Fair Labor Standards Act requires for non-exempt employees. An employee who works 45 hours at $20 an hour earns 40 × $20 = $800 in regular pay plus 5 × $30 = $150 in overtime, for $950 gross pay (the overtime calculator handles this for any rate). For salaried employees, divide the annual salary by the number of pay periods: $60,000 ÷ 26 = $2,307.69 per biweekly paycheck. Add bonuses, commissions and tips to gross pay before calculating withholdings, since they are taxable income too.

Step 3: Withhold Taxes and Deductions

• Federal income tax: Use the employee's W-4 and the IRS Publication 15-T tax tables. The amount depends on filing status, pay frequency and any adjustments the employee claimed.
• Employee FICA: Withhold 6.2% for Social Security (up to the annual wage base) and 1.45% for Medicare, plus the 0.9% Additional Medicare Tax on wages over $200,000. You match the 6.2% and 1.45% as the employer, which is what the calculator above shows; the 0.9% is employee-only.
• State and local taxes: Nine states have no income tax on wages, while others use flat rates, progressive brackets or local taxes on top of state taxes. Check with your state's Department of Revenue.
• Other deductions: Health insurance premiums, retirement contributions (401(k), SIMPLE IRA), garnishments such as child support or tax levies, and voluntary deductions like life insurance or HSA contributions. Pre-tax deductions reduce taxable income; post-tax deductions come out after taxes are calculated, so the order matters.

Step 4: Calculate Net Pay and Pay Your Team

Net Pay = Gross Pay − Tax Withholdings − Deductions

Net pay is the amount that reaches the employee's bank account or check. Most small businesses use direct deposit, which needs each employee's routing and account numbers plus enrollment with your bank or payroll provider. Most states also require a pay stub showing gross pay, every withholding and deduction, and net pay. Even where it isn't required, a pay stub cuts down on questions and protects you in disputes.

Step 5: Deposit and File Payroll Taxes

Payroll doesn't end when employees get paid. Withheld and employer taxes have their own deposit and filing deadlines:

The IRS penalty for a late deposit grows with the delay: it reaches 10% once a deposit is more than 15 days late and 15% after an IRS notice, so set reminders for every deadline.

Payroll Compliance Checklist

Use this checklist every pay period so nothing falls through the cracks:

Keep payroll records such as hours worked, pay rates, gross and net pay, and deductions for at least three years, as the FLSA requires, and keep employment tax records such as W-4s and Forms 941 and 940 for at least four years for the IRS.
