🧠 How this is calculated
Taxable income = income − adjustments − deduction (standard or itemized). Tax is the sum, over each bracket, of the rate × the part of your income inside that bracket, using the 2026 IRS tables. The child tax credit then reduces tax dollar for dollar after its income phase-out.
