Using the percentage method, calculate federal income tax withholding, if any, based on the following...

To calculate the monthly federal income tax (FIT) withholding for 2025, we first determine the monthly gross pay: $\$24,000 / 12 = \$2,000.00$. Next, we subtract the pretax medical insurance, which is exempt from FIT: $\$2,000.00 - \$27.00 = \$1,973.00$ (Union dues are post-tax and do not reduce taxable income). Using the 2025 percentage method for a Single filer with Step 2 unchecked, we account for the standard deduction. For a monthly period, the first portion of income (approximately $\$1,250$ in 2025) is taxed at 0% due to the standard deduction. The remaining taxable amount of roughly $\$723$ is taxed at the 10% bracket. After applying the specific IRS 15-T tables and banding, the resulting withholding is $\$72.30$. Accurate manual calculation is a vital skill for payroll professionals to audit system accuracy and handle manual adjustments for employees with lower annual earnings who may still have a tax liability.
