U.S. Tax Credits: A Complete Educational Guide
Credit vs. Deduction: What's the Difference?
Why Credits Are More Valuable
A deduction reduces your taxable income. In the 22% bracket, a $1,000 deduction saves you $220.
A credit reduces your actual tax bill dollar-for-dollar. A $1,000 credit saves you exactly $1,000.
Credits are generally more valuable than deductions of the same amount.
Types of Credits
- Refundable credits: If the credit exceeds what you owe, you receive the difference as a refund. Example: EITC
- Non-refundable credits: Can reduce your tax to $0 but cannot generate a refund. Example: Lifetime Learning Credit
- Partially refundable: A portion can generate a refund even with zero tax liability. Example: Child Tax Credit (refundable portion = ACTC)
