Formula Explained

The payroll tax calculation follows these steps:

Total Payroll Taxes

Total Payroll Taxes = FICA Taxes + State Income Tax + Local Taxes

FICA Taxes

FICA Taxes = (Gross Wages × 7.65%) + (Gross Wages × 1.45%)

Where 7.65% is the Social Security tax rate and 1.45% is the Medicare tax rate

State Income Tax

State Income Tax = Gross Wages × State Tax Rate

Local Taxes

Local Taxes = Gross Wages × Local Tax Rate

Note that some states have additional payroll taxes and deductions that may affect the final calculation. Always verify with your state's tax authority for precise requirements.

Worked Example

Let's calculate payroll taxes for an employee with $5,000 in gross wages, working in California with a 1% state tax rate and a 0.5% local tax rate.

Gross Wages: $5,000
State Tax Rate: 1%
Local Tax Rate: 0.5%

Calculation Steps

1. FICA Taxes: ($5,000 × 7.65%) + ($5,000 × 1.45%) = $382.50 + $72.50 = $455.00

2. State Income Tax: $5,000 × 1% = $50.00

3. Local Taxes: $5,000 × 0.5% = $25.00

4. Total Payroll Taxes: $455 + $50 + $25 = $530.00

The total payroll taxes for this employee would be $530.00.
