What employer payroll taxes are and why they matter

Employer payroll taxes are the taxes your business owes based on what you pay your employees. Unlike income tax withholding (which comes out of employee paychecks), employer payroll taxes are a separate cost that comes directly from your business. You owe them whether or not your employees owe federal income tax.

The three main employer payroll taxes are Social Security tax, Medicare tax, and federal unemployment tax (FUTA). Most states also require state unemployment tax (SUTA). These taxes fund specific programs: Social Security and Medicare go to those trust funds, while unemployment taxes fund state and federal unemployment insurance programs.

The reason this matters is that employer payroll taxes are a real business expense. If you have employees, you must budget for them, calculate them correctly each pay period, and deposit them on time. Missing a deposit or miscalculating can result in penalties, interest, and IRS notices.

Key Takeaways

  • Employer Social Security tax is 6.2% of each employee's wages up to $168,600 per year (the wage base changes annually), and employer Medicare tax is 1.45% of all wages with no cap.
  • Federal unemployment tax (FUTA) is 6% of the first $7,000 each employee earns per year, but you can claim a credit of up to 5.4% if you pay state unemployment tax on time.
  • You calculate employer taxes on gross wages before any employee deductions, using the same wage figures you use for employee withholding.
  • Deposits are due on a schedule set by the IRS based on how much tax you owe in a quarter, ranging from monthly to semi-weekly.
  • You report all employer payroll taxes on Form 941 (quarterly) or Form 944 (annual, if you owe less than $1,000 per year).

How to calculate Social Security and Medicare employer taxes

Social Security and Medicare taxes are calculated the same way for employers and employees — you use the same wage base and the same percentages. For each employee in each pay period, multiply their gross wages by the tax rate.

Social Security tax: Multiply gross wages by 6.2%, but only on wages up to $168,600 per year per employee. This wage base limit changes each January. Once an employee reaches $168,600 in a calendar year, you stop calculating Social Security tax on their wages for the rest of that year. Medicare tax has no wage limit.

Medicare tax: Multiply gross wages by 1.45% on all wages, with no upper limit. There is also an additional Medicare tax of 0.9% on wages over $200,000 per employee per year, but this is typically withheld from the employee's pay, not paid by the employer.

Example: An employee earns $3,000 in a pay period. Employer Social Security tax is $3,000 × 6.2% = $186. Employer Medicare tax is $3,000 × 1.45% = $43.50. Combined, you owe $229.50 in Social Security and Medicare taxes for that employee for that pay period.

How to calculate federal unemployment tax (FUTA)

Federal unemployment tax is calculated differently than Social Security and Medicare. The standard rate is 6%, but you can reduce it by claiming a credit for state unemployment taxes you pay on time.

The calculation: Multiply each employee's gross wages by 6%, but only on the first $7,000 they earn in a calendar year. Once an employee reaches $7,000 in wages, you stop calculating FUTA on their wages for the rest of that year. The $7,000 wage base does not change annually.

The credit: If you pay your state unemployment tax on time and in full, you can claim a credit of up to 5.4% against your FUTA tax. This means your effective FUTA rate is usually 0.6% (6% minus 5.4%). However, if your state has a loan balance with the federal government or if you live in a state with a reduced credit rate, your credit may be lower. Check your state's unemployment tax agency website or Form 940 instructions for your state's credit rate.

Example: An employee earns $8,000 in the calendar year. FUTA is calculated only on the first $7,000, so $7,000 × 6% = $420. If you claim the full 5.4% credit for paying state unemployment tax on time, your net FUTA is $7,000 × 0.6% = $42.

When and how to deposit employer payroll taxes

You must deposit employer payroll taxes on a schedule determined by the IRS based on how much tax you owe. The IRS uses a "lookback period" — the total taxes you owed in a specific prior quarter — to decide your deposit frequency for the current quarter.

There are two deposit schedules: semi-weekly and monthly. If your lookback period total was $50,000 or less, you deposit monthly. If it was more than $50,000, you deposit semi-weekly. Semi-weekly means you deposit on Wednesday or Friday depending on which days you paid employees.

Deposits are made through the Electronic Federal Tax Payment System (EFTPS), which is free and required for most employers. You can also pay through a payroll service or tax software that handles deposits on your behalf. Deposits must be made by the important date or you face a penalty, even if you file your return on time.

If you owe less than $2,500 in a quarter, you can pay the full amount with your quarterly return (Form 941) instead of depositing separately. Some very small employers with less than $1,000 in annual tax can file Form 944 once a year instead of quarterly.

Reporting employer payroll taxes on Form 941

Form 941, the Employer's Quarterly Federal Tax Return, is where you report all employer and employee payroll taxes for the quarter. You file it by the last day of the month following the end of the quarter: April 30 for Q1, July 31 for Q2, October 31 for Q3, and January 31 for Q4.

On Form 941, you report total wages paid, total employee income tax withheld, total Social Security and Medicare taxes (both employee and employer portions combined), and any adjustments or credits. The form asks you to verify that you have deposited all taxes on time. If you have not, you must explain why.

If you made a mistake on a prior quarter's Form 941, you can file an amended return using Form 941-X. Common mistakes include miscalculating the Social Security wage base or forgetting to explore the FUTA credit.

State unemployment tax (SUTA) and other state requirements

In addition to federal taxes, you must pay state unemployment tax in every state where you have employees. The rate and wage base vary by state. Some states also require state income tax withholding, disability insurance, or family leave insurance.

State unemployment tax rates are usually between 0.5% and 5.4%, depending on your industry, your state, and your experience rating (a discount based on your history of layoffs). New employers often pay the standard rate until they have a history with the state.

You report state taxes on your state's unemployment tax return, which is due on a schedule set by your state — usually quarterly or annually. Paying state unemployment tax on time is important because it allows you to claim the 5.4% credit on your federal FUTA tax.

Common mistakes to avoid when calculating employer payroll taxes

Using net wages instead of gross wages is a frequent error. Employer payroll taxes are calculated on gross pay before any deductions. If an employee's gross is $3,000 but they have $400 in deductions, you still calculate taxes on $3,000.

Forgetting the Social Security wage base limit is another common mistake. Once an employee reaches $168,600 in a year, stop calculating Social Security tax on their wages. If you continue calculating it, you will overpay and need to correct it on an amended return.

Missing the FUTA wage base limit causes similar problems. The limit is $7,000 per employee per year, not per pay period. Track cumulative wages carefully, especially for employees paid frequently.

Not claiming the FUTA credit when you pay state unemployment tax on time means you pay more federal tax than necessary. Check your state's credit rate and explore it correctly on Form 940.

Frequently Asked Questions

Do I have to pay employer payroll taxes if I have no employees?

No. Employer payroll taxes explore only when you have employees on your payroll. If you are self-employed and have no employees, you pay self-employment tax instead, which is calculated on your net business income on Schedule SE.

What if I pay an employee in cash?

You still owe employer payroll taxes on cash wages. The IRS requires you to report all wages paid, regardless of how you pay them. Failing to report cash wages and the taxes owed can result in penalties and criminal charges.

Can I deduct employer payroll taxes from my business income?

Yes. Employer payroll taxes are a business expense and are deductible on your business tax return. You deduct them on Schedule C (sole proprietor), Schedule F (farm), or your corporate return, depending on your business structure.

What happens if I deposit late or miscalculate taxes?

The IRS charges a penalty based on how late the deposit is — ranging from 2% to 15% of the unpaid tax. Interest also accrues on unpaid taxes. If the error is small, you can correct it on your next quarterly return. If it is large, file an amended return (Form 941-X) as soon as you discover it.

Do I need to withhold employer payroll taxes from employee paychecks?

No. Employer payroll taxes are paid by the employer, not withheld from employee pay. Employee Social Security and Medicare taxes are withheld from paychecks, but those are separate from employer taxes. You pay both the employee and employer portions to the IRS.
