Texas Second Job Calculator

How Your Second Job Income Is Calculated

This calculator applies a flat withholding rate — commonly used for second jobs — to estimate how much tax may be deducted from your paycheck.

Employers often apply a flat rate like 22% when you do not adjust your W-4 to include allowances or combine income from multiple jobs. In Texas, state income taxes may still apply to your second job income depending on your overall earnings.

You can also add pre-tax deductions such as insurance or retirement contributions to better reflect your actual take-home pay.

This tool provides an estimate only and should not be used for tax filing purposes. Always check with your employer or accountant if you have multiple sources of income.
