What are payroll taxes? Understanding the basics

Payroll taxes are the taxes directly tied to your employees’ wages. These taxes fund 3 programs: Security, Medicare, and unemployment insurance. These are not like income taxes, which are calculated on total earnings and settled at the end of the year. These are collected every pay cycle, and the cost is split between you and your employee.

The split, by the way, is what surprises founders the most. When you make your first US hire at USD $80,000 a year, your actual cost will not be USD $80,000. It will be closer to around USD $86,000 once you account for employer payroll taxes.

Following are the main elements to understand what are payroll taxes:

• Social Security: You and your employee each pay 6.2% on wages up to USD $176,100 (the 2026 wage base). Once an employee hits that ceiling, Social Security stops applying for them for the rest of the year.
  
• Medicare: You and your employee each pay 1.45% on all wages, with no cap. Employees earning over USD $200,000 also owe an additional 0.9% Medicare surtax, which you're required to withhold.
  
• FUTA (federal unemployment tax): Employer-only. The rate is 6% on the first USD $7,000 of each employee's wages. Most employers get a 5.4% credit for paying state unemployment taxes on time, bringing the effective rate to 0.6%, or USD $42 per employee per year.
  
• SUTA (state unemployment tax): Also employer-only. Rates vary by state. A new employer in Texas pays a different rate than one in California.
  

Founder Insight: Check your state's Department of Labor website for your SUTA rate, search "new employer unemployment tax rate" and you'll find it in under 2 minutes. Rates vary widely by state and update annually, so verify before you run payroll in any new state.

Social Security and Medicare taxes together are called FICA (Federal Insurance Contributions Act). You'll see this label on pay stubs and tax forms throughout your US operations.

Did you know? According to USAfacts, Payroll taxes, including Social Security and Medicare, made up around 34% of the federal revenue in 2025! This is a significant chunk for founders dealing with payroll taxes vs income taxes.

What is income tax

Income tax is basically what your employee owes the federal government, and most state governments based on everything they earn. It not just includes their wages, but also adds their investment income, rental income, and side income.

And your job as their employer is to withhold the right estimated amount from each paycheck from your company, based on your employee’s Form W-4. You will not pay their income tax, but will collect it on the government’s behalf and pass it along. The final amount is calculated when they file their annual return. Here are the main parts of income taxes:

• Taxable income: This goes beyond just your employees’ hourly pay or salary. It also includes earnings like interest, dividends, rental income, royalties, and profits from a business.
  
• Progressive tax rates: Federal income tax works on a progressive scale, which means the more money your employees make, the higher the rate becomes. The current federal brackets start at 10% and go up to 37%.
  
• Deductions and credits: These let you lower the amount of tax you owe. Deductions (such as home mortgage interest) reduce the income that gets taxed, while credits (like the Child Tax Credit) cut your tax bill directly.
  
• Withholding requirements: The tax ultimately belongs to the employee, but you as an employer must figure out and hold back the right amount from each paycheck using the details you provide on Form W-4.
  

What are the differences between payroll taxes vs income taxes

Alright—now let’s zoom out. Here are the main differences between payroll taxes and income taxes, in a quick glance format:

[Table:1]

Before you run your next payroll, here's what to keep track of:

Per payroll:

• Withhold federal income tax based on Jordan's W-4
  
• Withhold employee FICA (6.2% Social Security + 1.45% Medicare)
  
• Calculate and set aside your employer FICA match
  
• Set aside FUTA/SUTA contributions
  

Quarterly:

• File Form 941 and follow your deposit schedule (semi-weekly or monthly)
  

Annual:

• Send W-2s to all employees by Jan 31
  
• File Form 940 (FUTA return) by Jan 31
  
• File Form 1099-NEC for any contractors paid USD $600 or more
  

How to Calculate Payroll Taxes vs Income Taxes

By understanding how to calculate both the taxes, you will remove a major chunk of stress for your company. Let’s understand this with an example. Say your first US hire, Jordan, earns USD $100,000 a year. Here is how to figure payroll taxes and income taxes for a single employee:

Figure Payroll Taxes

Jordan's deductions (withheld from paycheck):

• Social Security: USD $100,000 x 6.2% = USD $6,200
  
• Medicare: USD $100,000 x 1.45% = USD $1,450
  
• Jordan's total FICA deduction: USD $7,650
  

Your costs as the employer (on top of salary):

• Social Security match: USD $6,200
  
• Medicare match: USD $1,450
  
• FUTA (0.6% effective on first USD $7,000): USD $42
  
• SUTA: depends on your state
  
• Total employer payroll tax cost: USD $7,692 plus SUTA
  

Jordan's salary is USD $100,000. Your actual cost to employ Jordan is USD $107,692 or more, before benefits and overhead. Note that the income tax calculation below is based on Jordan's full annual earnings, not a single paycheck. When you understand how to calculate payroll taxes upfront, that number stops being a surprise.

Calculating Income Taxes

Now, Jordan files as a single filer. After the USD $16,100 standard deduction, the taxable income is USD $83,900. Now, after applying the 2026 brackets:

• 10% on first USD $11,925: USD $1,192.50
  
• 12% on USD $11,926 to USD $48,475 (USD $36,549): USD $4,385.88
  
• 22% on USD $48,476 to USD $83,900 (USD $35,424): USD $7,793.28
  

Total estimated federal income tax: USD $13,371.66

Rounded to the nearest dollar: USD $13,372

Jordan does not pay 22% on all of his USD $83,900. Only on the slice in that bracket. And as his employer, you withhold an estimated share from each paycheck based on Jordan’s W-4, and the exact amount settles when Jordan files his annual return.

Here is a tip: Always verify the brackets, standard deductions, and wage bases as they change annually. Make sure to confirm the current figures against IRS Publication 15-T before you run real calculations.

Net vs gross pay: How taxes impact your team’s take-home Net vs Gross Pay: How Taxes Impact your Team’s Take-Home

Being a good employer not just includes understanding the impact on the business, but also includes understanding the impact of different factors on your employees’ final take home and earnings, which means understanding net vs gross pay, apart from understanding payroll taxes vs income taxes.

Gross pay is the number on Jordan’s offer letter: USD $100,000. The net vs gross pay is the gap that employees always notice. For Jordan, annual deductions include FICA, the federal income tax withholding, and the state income tax if it is applicable. After all the deductions, someone earning USD $100,000 in a mid-tax state usually takes home USD $65,000 to USD $70,000, the amount varies state to state according to the applicable taxes. Understanding this equation helps avoid confusion on both sides.

• A few things you need to make note of that make changes to the net pay number:Pre-tax benefits: 401(k) contributions and health insurance premiums paid pre-tax reduce taxable income and sometimes FICA. Jordan's take-home goes up if they elect these.
  
• State income tax: Zero in Florida and Texas, up to 13.3% in California. Where your employees are based changes their net vs gross pay meaningfully.
  
• W-4 elections: Jordan's W-4 tells you how much income tax to withhold. Encourage your team to update it after major life changes.
  
• Additional Medicare Tax: Once Jordan earns over USD $200,000, you're required to withhold an extra 0.9%. This catches some founders off guard at bonus time.
  

Being transparent with your team builds trust. Employees who understand their paycheck are less likely to come to you confused about where their money went.

Common payroll taxes vs income taxes mistakes founders make

Not budgeting for employer payroll taxes

When you offer Jordan USD $100,000, you're committing to USD $107,692 or more before benefits. Founders who budget for salary alone hit a cash crunch at their first payroll run. Calculate the full headcount cost, including all employer payroll taxes, before you make any offer.

Misclassifying contractors as employees

If you pay someone as a 1099 contractor when they should legally be a W-2 employee, you're liable for the employer payroll taxes you didn't withhold, plus penalties and interest. The IRS has clear tests for classification. Get it right before you issue the first payment.

Missing quarterly deposit deadlines

Payroll tax withholdings aren't held until year-end. They're deposited to the IRS either semi-weekly or monthly, depending on your deposit schedule. Form 941 (your quarterly payroll tax return) has hard deadlines: April 30, July 31, October 31, and January 31. Missing them triggers penalties that start at 2% and compound.

Key strategies to manage payroll taxes vs income taxes efficiently as a business owner

If you make smart choices as a founder, your business will grow with lesser hiccups, and your employees will be happier. So, here are some of the best practices you can follow while managing payroll taxes vs income taxes:

• Classify your workers correctly. Understand which ones are the employees(W-2) and which ones are contractors(1099) to avoid any taxation and legal issues later while payment. If you get confused, you might get some unpleasant surprises later.
  
• Stick to the deadlines by the IRS as missing them may lead to fines, more wastage of funds, incorrect calculations, and lots of stress.
  
• Be updated with the latest updates about payroll taxes vs income taxes. The updates occur timely and missing out on them may lead to wrong and outdated calculations.
  
• Once you grow past a certain number of employees, consider outsourcing payroll to experts
  
• If you have remote or global teams, figure payroll taxes and income taxes on the basis of US rules for American Workers and use tax treaties for your international staff.
  

The IRS forms you should know while dealing with payroll taxes vs income taxes

• Form W-4: Your employee fills this in on day one. It mentions how much federal income tax to withhold. Not a one-time form, your team should update it after major life changes.
  
• Form 941: Filed quarterly. Reports wages paid, income tax withheld, and FICA owed. Deadlines: April 30, July 31, October 31, and January 31.
  
• Form W-2: Sent to each employee by January 31 each year. Summarises annual wages and taxes withheld.
  
• Form 940: Annual FUTA return. Due January 31.
  
• Form 1099-NEC: For contractors, not employees. If you paid a contractor USD $600 or more in the year, you file this. You don't withhold taxes for contractors, that's their responsibility.
  

Conclusion

Payroll taxes vs income taxes will show up in every payroll you run for as long as you employ people in the US. Founders who handle it well aren't doing anything complicated. They know what they owe, they've budgeted accurately, and they meet every deadline without stress and too many confusions..

Get clear on the distinction now. Understand your real headcount cost, with employer payroll taxes included, before you make your next offer. Set your deposit calendar before the first payroll runs. Know the difference between net vs gross pay before your first hire asks about their paycheck.

After that, it's just part of building your company.

Frequently Asked Questions

What is the main difference between payroll taxes vs income taxes?

Payroll taxes are split between you and your employee and fund Social Security, Medicare, and unemployment. Income taxes are paid by your employee alone, based on total earnings, and fund broader government operations.

What are payroll taxes, and what do they include?

Payroll taxes include Social Security (6.2% each), Medicare (1.45% each), FUTA, and SUTA. Your share as the employer adds roughly 7.65% on top of every dollar of wages you pay.

How do I figure payroll taxes for a new hire?

To figure payroll taxes, apply 6.2% Social Security and 1.45% Medicare to gross wages, then add FUTA at 0.6% on the first $7,000 and your state's SUTA rate. Learning how to calculate payroll taxes for each hire upfront keeps your headcount budget accurate.

What is net vs gross pay, and why does it matter?

Gross pay is what you agree to pay; net vs gross pay is the gap your employee notices when their paycheck lands, typically 25 to 35% less after income tax withholding and payroll tax deductions. Setting honest expectations about net vs gross pay before an offer prevents difficult conversations later.

Do employer payroll taxes apply to contractors?

Employer payroll taxes only apply to W-2 employees, not 1099 contractors, who handle their own self-employment taxes covering both sides of FICA. Misclassifying an employee as a contractor makes you liable for all unpaid employer payroll taxes plus penalties when the IRS reclassifies them.
