The tax rate and standard deduction are determined based on the employee's filing status and the 2015 tax brackets.

Worked Example

Let's calculate the payroll taxes for an employee with a gross pay of $50,000 and a filing status of "Single".

1. Social Security Tax: $50,000 × 6.2% = $3,100
2. Medicare Tax: $50,000 × 1.45% = $725
3. Federal Income Tax Withholding:
   • Standard Deduction for Single: $6,300
   • Taxable Income: $50,000 - $6,300 = $43,700
   • Tax Rate for $43,700: 25% (2015 bracket)
   • Tax Before Credits: $43,700 × 25% = $10,925
   • Tax Credits: $900 (Personal Exemption)
   • Federal Income Tax: $10,925 - $900 = $10,025
4. Total Payroll Taxes: $3,100 + $725 + $10,025 = $13,850

Using the calculator with these inputs will give you the same result.
