A tax credit cuts your tax bill dollar-for-dollar; a tax deduction only reduces the income your tax is calculated on, so it's worth your marginal rate. That means a $1,000 credit saves the full $1,000, while a $1,000 deduction saves just $220 at a 22% rate. Credits win — by a lot.
Quick verdict
A credit beats a deduction of the same size every time. When you can choose (some education and energy benefits, for example, come as either), take the credit. And always check whether a credit is refundable — a refundable credit can pay you even if you owe no tax.
Tax credit vs tax deduction at a glance
| Factor | Tax credit | Tax deduction |
|---|---|---|
| What it reduces | ✅ Your tax bill directly | Your taxable income |
| Value of $1,000 | ✅ $1,000 saved | $220 at a 22% rate |
| Depends on tax bracket | ✅ No — same for everyone | Yes — worth more at higher rates |
| Can it create a refund? | ✅ If refundable | No |
| Examples | Child Tax Credit, EITC, energy credits | Mortgage interest, IRA, charity |
A worked example
Imagine you're in the 22% bracket and you have $1,000 of a tax benefit:
- As a credit: your tax bill drops by the full $1,000.
- As a deduction: your taxable income drops by $1,000, which saves $1,000 × 22% = $220.
Same headline number, more than four times the saving from the credit. That's why credits are so prized — and why deductions are worth more to people in higher brackets (a $1,000 deduction saves $370 at the 37% rate).
Refundable vs non-refundable credits
One more wrinkle: a refundable credit can take your tax below zero and pay you the difference as a refund (the Earned Income Tax Credit is the classic example). A non-refundable credit can only reduce your tax to zero — any excess is lost. When comparing credits, a refundable one is more valuable if your tax bill is small.

Frequently asked questions
What is the difference between a tax credit and a tax deduction?
A credit reduces the tax you owe dollar-for-dollar ($1,000 credit = $1,000 less tax). A deduction reduces taxable income, saving only your marginal rate ($1,000 deduction at 22% = $220). Credits are almost always more valuable.
Is a tax credit better than a deduction?
Yes, dollar for dollar — a credit cuts your bill directly while a deduction only reduces the income tax is figured on, so a credit of a given size saves more.
What is a refundable tax credit?
One that can reduce your tax below zero and pay you the difference as a refund. A non-refundable credit only reduces tax to zero; any leftover is lost.
How much is a tax deduction worth?
Its amount × your marginal rate. A $5,000 deduction saves $1,100 at 22% or $1,850 at 37% — the higher your bracket, the more it's worth.
