Tax Deductions vs. Tax Credits
| Tax Deduction | Tax Credit | |
|---|---|---|
| How it works | Reduces taxable income | Reduces tax owed directly |
| Value of $1,000 (22% bracket) | Saves $220 | Saves $1,000 |
| Examples | Standard deduction, 401(k) | Child Tax Credit, EITC |
| Types | Above-the-line or itemized | Refundable or nonrefundable |
Credits are more valuable than deductions of the same dollar amount because they reduce your tax bill directly.
