How this is calculated
Adjusted gross income is your wages plus other ordinary income, minus above-the-line adjustments. The larger of your standard deduction or your itemized total comes off that, and the remainder runs through the seven federal brackets one slice at a time. That is why your marginal bracket is never the rate you actually pay on the whole amount.
The child tax credit is applied at the statutory amount per qualifying child, reduced by $50 for every $1,000 of income above the phase-out threshold, with the refundable portion limited to 15 percent of earned income above $2,500. The 65-and-older bonus deduction phases out at 6 percent of income above its threshold.
Bracket, standard deduction and credit figures come from the IRS annual inflation adjustments: tax year 2026 and current federal rates and brackets. This is an estimate for planning, not a prepared return. It does not model state tax, the alternative minimum tax, the earned income credit, education credits or the premium tax credit.
