How to Calculate Social Security Tax in Excel

What Is Social Security Tax?

The Social Security tax is a dedicated payroll tax that funds Old-Age and Survivors Insurance and Disability Insurance. With each paycheck, a predetermined percentage is deducted to cover this tax. Introduced in 1937, the initial rate was 1% for employees, aiming to provide retirement benefits.

Both employees and employers are responsible for paying the Social Security tax. As of 2021, the individual contribution rate is 6.2% of wages for both parties. Self-employed individuals pay 12.4%. The maximum taxable amount for 2021 was $142,800, subject to annual adjustments.

As the tax rate is different, we’ll demonstrate the calculations in two sections:

• For an employer or employee
• For a self-employed individual

For Employers or Employees

• Tax Rate and Maximum Limit:
  • In 2021, both employers and employees are required to pay 6.2% of their wages as Social Security Tax.
  • The maximum taxable amount for 2021 was $142,800.
  • Note that tax rates and limits may vary by region and change annually.

• Calculation Using the IF Function:
  • Suppose your total income is $130,000.

• • To calculate the Social Security Tax, follow these steps:
    • Activate Cell D9.
    • Insert the following formula:

• Press Enter.

• • The formula checks if the income (D8) is less than or equal to the maximum limit (D4). If so, it calculates 6.2% of the income; otherwise, it uses the maximum limit.

• Example:
  • If you input $150,000, the formula will return 6.2% of $142,800 (the maximum limit), which is $8,854.
  • This happens because the income exceeds the maximum taxable limit.

For Self-Employed Individuals

• Total Tax Rate:
  • Self-employed individuals need to pay both the employer’s tax (6.2%) and the employee’s tax (6.2%).
  • The total tax rate for self-employment is 12.4% (6.2% + 6.2%).

• Calculation Using the IF Function:
  • Let’s assume a self-employed person has a total income of $140,000.
  • Follow these steps:
    • Insert the following formula in Cell D9:

• • • Press Enter.

• Example:
  • If you enter $225,000 (which exceeds the maximum limit), the formula will return the percentage of the maximum value ($142,800).
