For business owners, "payroll taxes" instantly triggers stress, and for good reason. Complex calculations, shifting rules, and looming IRS deadlines mean a single misstep can lead to significant penalties (averaging $1,300 per quarter for recurring issues), wasted time, and even personal legal risk. Beyond cutting checks, you're legally obligated to collect, pay, and report employee wages. This responsibility becomes even more critical with multi-state employees, a blended workforce (contractors/W-2), or complex compensation like bonuses and fringe benefits with special tax treatment.
At Lift HCM, we’ve managed payroll taxes for thousands of companies across the U.S. for over 50 years. We’ve seen how small errors can turn into expensive problems—and how avoidable they often are with the right systems.
This article will walk you through everything you need to know about payroll taxes in 2025: from who pays what, how to calculate withholdings, forms and deadlines you can’t miss, to the tools that make staying compliant simple. Whether you’re running payroll for the first time or fine-tuning your existing system, you’ll walk away with clarity—and confidence.

Payroll taxes are split into two parts—what you withhold from employees, and what you pay as an employer.
Employee-paid taxes are withheld from wages and include Social Security, Medicare, and income taxes. Employers are responsible for additional contributions like matching FICA taxes and paying unemployment taxes. These taxes fund programs such as Social Security, Medicare, and unemployment insurance.
Non-compliance can lead to penalties, interest, and even personal liability under IRS rules.
Over 40% of small businesses face payroll tax penalties each year, averaging $845. Mistakes can trigger audits or enforcement actions, with penalties for late deposits ranging from 2% to 15%. What's even scarier? The IRS can hold business owners personally liable for unpaid withholdings via the Trust Fund Recovery Penalty (TFRP).
Let's break down the key payroll taxes you'll encounter as an employer:

Your calculation process starts with the employee's Form W-4, which outlines their tax filing status and withholding preferences. Let's walk through a simplified example calculation:
Calculate gross pay: This is the total earnings before any deductions (e.g., hours worked x pay rate or salary).
Use IRS and state tax tables to calculate income tax withholding. This amount is based on the employee's gross pay, W-4 elections, and the applicable tax brackets.
Withhold FICA taxes (Social Security and Medicare). These are fixed percentages of gross wages.
Add your share of FICA and unemployment taxes. As the employer, you're responsible for matching FICA and paying unemployment taxes.
The chart below breaks down the employer's tax obligation across five salary levels, showing how each tax type (Social Security, Medicare, FUTA, SUTA) contributes to the total burden. The stacked format illustrates how the proportion of each tax changes as salaries increase, particularly the impact of the Social Security wage base limit.
Employers are legally required to handle four critical tax functions with precision and timeliness to avoid penalties. These are the foundational pillars of payroll tax compliance:
This is the initial and ongoing step where you, as an employer, deduct various taxes directly from your employees' gross pay.
Action: Calculate and Withhold
Federal Income Tax: Based on IRS tax tables and employee W-4 forms.
State Income Tax: (If applicable) Based on state tax tables and employee state withholding forms.
Local Income Tax: (If applicable) Based on local municipality rules.
FICA Contributions (Employee Share):
Social Security Tax: 6.2% of wages up to the annual Social Security wage base limit.
Medicare Tax: 1.45% of all wages, plus an additional 0.9% Medicare tax on wages exceeding a certain threshold ($200,000 for single filers).
Other Items:
Garnishments: Court-ordered deductions (e.g., child support, creditor payments).
Retirement Contributions: Employee 401(k) or other plan contributions.
Health Insurance Premiums: Employee share of premiums.
In addition to withholding from employees, you, as the employer, have your own tax obligations.
Action: Calculate and Pay Employer Taxes
Matching FICA Contributions:
Social Security Tax: An additional 6.2% of wages up to the annual Social Security wage base limit.
Medicare Tax: An additional 1.45% of all wages.
(Total FICA = 12.4% Social Security + 2.9% Medicare, split evenly between employer and employee)
Unemployment Taxes:
FUTA (Federal Unemployment Tax Act): Paid to the federal government.
SUTA (State Unemployment Tax Act): Paid to your state government; rates vary based on state laws and your unemployment history.
Applicable Local Business Taxes: (If required by your city or county)
Once calculated, these withheld and employer-side taxes must be remitted to the appropriate tax authorities.
Action: Deposit Taxes On Time
Method: Primarily via the Electronic Federal Tax Payment System (EFTPS) for federal taxes. State and local taxes have their own specific payment methods.
Frequency: Your deposit schedule is determined by your tax liability history from a previous 12-month "lookback period" as defined by the IRS.
Semi-weekly: If your total tax liability for the lookback period was more than $50,000.
Monthly: If your total tax liability for the lookback period was $50,000 or less.
Key Point: It's crucial to know your correct schedule to avoid penalties.
Beyond deposits, you must submit various forms to report your payroll tax activities.
Action: File Accurate Forms by Deadlines
Form 941 (Employer's QUARTERLY Federal Tax Return):
Purpose: Reports withheld federal income tax, Social Security tax, and Medicare tax.
Deadlines:
Q1 (Jan-Mar): April 30
Q2 (Apr-Jun): July 31
Q3 (Jul-Sep): October 31
Q4 (Oct-Dec): January 31 of the following year
Form 940 (Employer's Annual Federal Unemployment (FUTA) Tax Return):
Purpose: Reports your annual FUTA tax liability.
Deadline: January 31 of the following year (or February 10 if you deposited all FUTA tax on time).
W-2/W-3 Year-End Wage Summaries:
Form W-2 (Wage and Tax Statement): Provided to each employee, detailing their annual wages and taxes withheld.
Form W-3 (Transmittal of Wage and Tax Statements): Sent to the Social Security Administration (SSA) along with all W-2 forms, summarizing all W-2 data.
Deadlines: January 31 of the following year for both forms (to employees and SSA).
State & Local Forms: Don't forget any required state unemployment tax reports, state withholding reports, and local payroll tax forms.
Payroll tax credits are federal incentives that reduce employment costs, promote hiring from target groups, and aid employee retention. These credits can lower payroll taxes and may be refundable, offering payments if they exceed tax liability. Proper documentation and claims can significantly lessen your payroll burden.
Eligibility Requirements and Estimated Savings:
| Tax Credit | Who Qualifies | Maximum Benefit | Documentation Required |
|---|---|---|---|
| R&D Credit | Any business developing/improving products, processes, software, or formulas | Dollar-for-dollar tax reduction; startups can offset payroll taxes up to $500,000 annually | IRS Form 6765, substantiated by records |
| WOTC | Employers hiring from target groups | $2,400–$9,600 per eligible employee | Form 8850 submitted within 28 days of hire |
| State Training Credits | Varies by state | 0.5–2% SUTA rate reduction | Training records and certification |
| Employee Retention Credit (ERC) | Businesses impacted by COVID-19 | $5,000/employee (2020), $28,000/employee (2021) | Payroll tax forms (Form 941/941-X) |
| Paid Family/Sick Leave | Employers providing COVID leave | Up to $10,000/employee | Payroll tax forms (Form 941) |
| Small Business Health Care | Small employers with health coverage | 50% of premiums (2 years) | Income tax return |
