A single taxpayer with income of $34,000 and deductions of $14,000 has taxable income of $20,000 ($34,000 - $14,000 = $20,000). Using the 2023 tax rate schedule for the single filing status, the income tax liability is $2,180.00 ($2,194.50 in 2022).

Can someone explain how they got the income tax liability to become $2,180?
