Welcome to your informational hub for understanding the complexities of payroll taxes across the United States — a one-stop destination for both federal and state-specific taxation summary details tailored to employers, employees, and the self-employed.

Federal Payroll Tax Breakdown :

Understanding Federal Payroll Taxes is crucial for both employees and employers. Here’s what you need to know:

  1. Federal Income Tax Withholding: Employee earnings are subject to withholding, based on their W-4 form details.
  2. Social Security Contributions: A 6.2% contribution rate applies to both employees and employers to support this essential benefits program.
  3. Medicare Contributions: Each party contributes 1.45% of wages to Medicare, with additional taxation for high-income earners.
  4. Additional Medicare Levy: A supplementary 0.9% tax applies to employees exceeding a specified income threshold.
  5. Federal Unemployment Tax (FUTA):This employer-only tax, generally at 6%, supports state unemployment funds, with potential credits reducing the rate.

Keep in mind, the 401(k) plans stand as a beacon of retirement savings, underscoring the long-term value of understanding federal taxes.

401 (K) Contribution Limits: There are annual contribution limits set by the IRS. As of my last knowledge update in January 2022, for individuals under the age of 50, the annual contribution limit is $19,500. For those aged 50 and older, there is a “catch-up” contribution option allowing an additional $6,500, bringing the total to $26,000.

State-by-State Payroll Tax Guide

Payroll taxes vary widely by state, with intricate regulations including:

  1. State Income Taxes: Employee earnings are taxed at diverse rates and brackets.
  2. State Unemployment Taxes (SUTA):Funding for state unemployment benefits falls on the employer, with varied rates.
  3. Disability Insurance (DI) and Paid Family Leave (PFL): Specific states mandate contributions toward disability insurance and family leave benefits.

After a hiatus post-war, the modern income tax emerged with the Sixteenth Amendment in 1913, adopting payroll withholding during WWII. Today’s federal tax system is progressive, with a tiered rate structure enhancing or reducing your burden relative to your income.

The most commonly used federal withholding form is the Form W-4 and tells your employer how much money to withhold from your paycheck for federal income tax. Completing your W-4 accurately helps avoid too much or too little tax being withheld from your paycheck.

Anytime you move or have a major life change (for example: marriage, divorce, birth of a child) always be sure to complete a new W4.
