Bottom line: Tax credits are more valuable than tax deductions of the same amount. A $1,000 credit cuts your tax bill by $1,000. A $1,000 deduction cuts your taxable income by $1,000, saving you $220 if you are in the 22% bracket. Credits always win.
Tax deductions and tax credits are both ways to reduce what you owe the government. They work differently and are worth different amounts. Confusing the two — especially when comparing strategies — leads to poor decisions about what is actually worth pursuing.
How Tax Deductions Work
A deduction reduces your taxable income — the income on which your tax is calculated.
Example: Your gross income is $80,000. You have $15,000 in deductions (standard deduction). Your taxable income is $65,000. You pay tax on $65,000, not $80,000.
How much is a $1,000 deduction worth? It depends on your marginal tax rate (the rate on the last dollar of income):
- 10% bracket: saves you $100
- 22% bracket: saves you $220
- 32% bracket: saves you $320
- 37% bracket: saves you $370
Higher earners benefit more from deductions. A deduction worth considering for a high earner may be relatively less valuable for a lower earner.
How Tax Credits Work
A credit reduces your tax bill directly — it comes off the tax calculated after deductions are applied.
Example: After applying deductions, your tax bill is $8,000. You have a $2,000 Child Tax Credit. Your tax bill becomes $6,000.
How much is a $1,000 credit worth? $1,000, regardless of your tax bracket. That is the power of credits — they are not reduced by your income or marginal rate.
Refundable vs. Non-Refundable Credits
Non-refundable credits: Can reduce your tax bill to zero but not below. If you owe $800 and have a $1,000 non-refundable credit, your bill goes to $0 but you do not receive $200 back.
Refundable credits: Can generate a refund even if you owe no tax. If you owe $0 and have a $1,000 refundable credit, you receive $1,000 as a refund. The Earned Income Tax Credit (EITC) is the largest refundable credit for working-age filers.
Partially refundable credits: A portion is refundable. The Child Tax Credit has a refundable portion (the "Additional Child Tax Credit") that allows lower-income parents to receive a refund even with low or no tax liability.
- Never spend money to get a deduction. A $1,000 charitable donation saves you $220 at the 22% rate — you are net down $780. Giving is worthwhile for non-tax reasons, but structuring spending around deductions assumes the tax benefit outweighs the cost, which it usually does not.
- Above-the-line deductions (like student loan interest, traditional IRA contributions, and HSA contributions) reduce your Adjusted Gross Income and can make you eligible for credits or deductions that phase out at higher income. These are often more valuable than below-the-line itemized deductions.
- When evaluating whether to pursue a deduction — for example, contributing to a traditional IRA instead of a Roth — think in terms of your effective tax rate benefit, not just the deduction amount.
Common Deductions
Standard deduction: The simplest option. $15,000 (single) or $30,000 (married) in 2026 (approximate). No documentation required — everyone qualifies.
Itemized deductions (above standard): Worth itemizing only if totals exceed the standard amount:
- Mortgage interest (Form 1098)
- State and local taxes (SALT) — capped at $10,000
- Charitable contributions (cash and non-cash)
- Medical expenses exceeding 7.5% of AGI
Above-the-line deductions (available even with standard deduction):
- Traditional IRA contributions (subject to income limits if you have a workplace plan)
- Student loan interest (up to $2,500, phases out at higher income)
- HSA contributions
- Educator expense deduction ($300 for K-12 teachers)
- Alimony (for agreements before 2019)
Common Credits
Earned Income Tax Credit (EITC): Up to $7,830 for lower-income workers with children. Refundable. One of the most significant credits available to working families.
Child Tax Credit: Up to $2,000 per qualifying child under 17. Partially refundable.
Child and Dependent Care Credit: Up to $1,050 for childcare costs (single child).
American Opportunity Credit (education): Up to $2,500 per student per year for first four years of college. 40% refundable.
Retirement Savings Contribution Credit (Saver's Credit): Up to $1,000 for lower-income filers who contribute to a retirement account.
