What are Tax Deductions and Credits?
Tax deductions and credits are two different ways to reduce what you owe. Deductions lower your taxable income; credits directly reduce your tax bill, making credits more valuable.
A tax deduction reduces your taxable income (saves 10–37% depending on bracket); a tax credit directly cuts your tax bill by the credit amount.

Step-by-step worked examples
$80,000 income, $10,000 itemized deduction, 22% tax bracket. Tax savings from deduction?
Taxable income after deduction = $80,000 − $10,000 = $70,000. Tax at 22% = $70,000 × 0.22 = $15,400. Without deduction = $80,000 × 0.22 = $17,600. Savings = $17,600 − $15,400 = $2,200.
$15,000 tax liability, $2,500 Child Tax Credit (non-refundable). Tax owed?
Tax liability before credit = $15,000. Apply $2,500 credit. Tax owed = $15,000 − $2,500 = $12,500.
Standard deduction 2024: $14,600. Estimate tax savings vs. no deduction at 24% bracket.
Tax with standard deduction: ($80,000 − $14,600) × 0.24 = $15,686. Tax with $0 deduction: $80,000 × 0.24 = $19,200. Savings = $19,200 − $15,686 = $3,514.
