At its simplest, a tax credit is a dollar-for-dollar reduction of the income tax you owe. If you owe $1,500 in federal taxes and qualify for a $600 tax credit, your tax bill drops to $900. Unlike a tax deduction, which reduces the amount of income subject to tax, a tax credit directly reduces the tax itself. This makes credits generally more valuable than deductions of the same amount. Tax credits are designed by the government to encourage specific behaviors — such as raising children, pursuing higher education, saving for retirement, or installing energy-efficient equipment. Understanding how they work, which ones you may qualify for, and how to claim them can significantly lower your tax bill or even generate a refund.
How Tax Credits Work: Non-Refundable vs. Refundable
Tax credits fall into two main categories: non-refundable and refundable. The distinction is critical because it determines whether a credit can reduce your tax liability to zero and then provide a refund for any leftover amount.
Non-refundable credits can only reduce your tax liability to zero. If your tax bill is $1,000 and you have a non-refundable credit of $1,200, the credit wipes out the $1,000 you owe, but the extra $200 is lost — you cannot get it back as a refund. Common non-refundable credits include the Child and Dependent Care Credit and the Lifetime Learning Credit.
Refundable credits, on the other hand, allow you to receive the excess over your tax liability as a refund. For example, if you owe $500 and qualify for a refundable credit of $1,000, the IRS will apply $500 to your tax bill and send you a $500 refund. Refundable credits are especially valuable for low-income taxpayers who may have little or no tax liability. The Earned Income Tax Credit (EITC) and the refundable portion of the Child Tax Credit are the most well-known refundable credits.
Some credits are partially refundable. The Child Tax Credit, for example, is worth up to $2,000 per qualifying child (as of 2024), but only up to $1,700 of that amount is refundable (the Additional Child Tax Credit). The non-refundable portion reduces your tax bill, and the refundable portion can generate a refund even if you owe no tax.
Common Types of Tax Credits
Below is a table of major tax credits available to individual taxpayers, with approximate maximum amounts for the 2024 tax year. Actual amounts adjust annually for inflation and are subject to income limits.
| Credit Name | Maximum Amount (Approx.) | Refundable? | Purpose |
|---|---|---|---|
| Earned Income Tax Credit (EITC) | Up to $7,430 (with 3 children) | Yes (fully refundable) | Supports low- to moderate-income workers |
| Child Tax Credit (CTC) | $2,000 per qualifying child | Partially refundable (up to $1,700) | Helps families with dependent children |
| American Opportunity Tax Credit (AOTC) | $2,500 per eligible student | Partially refundable (up to $1,000) | Covers first four years of higher education |
| Lifetime Learning Credit (LLC) | $2,000 per tax return | No (non-refundable) | Education expenses beyond the first four years |
| Saver’s Credit (Retirement Savings Contributions Credit) | $1,000 ($2,000 if married filing jointly) | No (non-refundable) | Encourages retirement savings for low- and moderate-income earners |
| Premium Tax Credit (Health Insurance Marketplace) | Varies by income and plan cost | Yes (advanceable, refundable) | Helps pay for health insurance purchased through the Marketplace |
Each credit has its own set of rules. For example, the AOTC is available only for the first four years of post-secondary education, while the LLC has no limit on the number of years you can claim it. The EITC amount depends on your earned income and number of qualifying children, with a much smaller credit available for workers without children.
Eligibility and Limitations
Tax credits are typically subject to income phase-outs. Your eligibility is determined by your adjusted gross income (AGI) and, in some cases, your modified adjusted gross income (MAGI). The phase-out range is the income window where the credit amount gradually decreases until it reaches zero.
Here are approximate 2024 phase-out ranges for some key credits:
- EITC: For a single filer with one child, the credit begins to phase out at $22,610 of AGI and disappears at $49,560. For married filing jointly with three children, the phase-out starts at $30,000 and ends at $66,820.
- Child Tax Credit: The $2,000 per child credit begins to phase out at $200,000 AGI ($400,000 for married filing jointly). The credit is reduced by $50 for every $1,000 of income above the threshold.
- American Opportunity Tax Credit: Phase-out begins at $80,000 AGI ($160,000 for married filing jointly) and completely phases out at $90,000 ($180,000).
- Lifetime Learning Credit: Phase-out range is $80,000–$90,000 AGI ($160,000–$180,000 for married filing jointly).
- Saver’s Credit: Available only to taxpayers with AGI under $38,250 ($76,500 married filing jointly) in 2024.
Other eligibility factors include the age of dependents, enrollment status for education credits, and whether you have a valid Social Security number. The EITC and Child Tax Credit, for example, require that the child have a valid SSN and be under age 19 or 24 if a student (or permanently disabled).
How to Claim Tax Credits
Claiming a tax credit requires you to file a federal income tax return — even if you don’t otherwise owe tax — and complete the appropriate IRS forms and schedules. The specific forms depend on the credit:
- Earned Income Tax Credit: File Form 1040 and attach Schedule EIC if you have qualifying children. For workers without children, you can claim the credit directly on Form 1040.
- Child Tax Credit: Claimed on Form 1040, Schedule 8812 is required for the additional (refundable) portion.
- Education credits (AOTC and LLC): Use Form 8863 and attach to Form 1040. You will need IRS Form 1098-T from the educational institution.
- Saver’s Credit: File Form 8880 along with your 1040. You must be at least 18 and not a full-time student.
- Premium Tax Credit: If you had advance payments of the credit (paid to your insurer), you must file Form 8962 to reconcile the amounts. If you didn’t take advance payments, you can claim the credit on Form 8962.
Many taxpayers overlook credits simply because they don’t know they qualify. For example, the EITC is frequently unclaimed by eligible workers without children. The IRS estimates that about one in five eligible taxpayers fails to claim the EITC each year. Using free tax preparation software or consulting a tax professional can help identify credits you may be missing.
Frequently Asked Questions
What is the difference between a tax credit and a tax deduction?
A tax deduction reduces your taxable income, which lowers your tax bill by your marginal tax rate. For example, a $1,000 deduction for someone in the 22% bracket saves $220. A tax credit of $1,000, however, reduces your tax bill by the full $1,000 regardless of your tax bracket. Credits are generally more valuable than deductions of the same amount.
Can a tax credit give me a refund if I don’t owe any tax?
Yes, but only if the credit is refundable. Non-refundable credits can only reduce your tax liability to zero; any excess is lost. Refundable credits, such as the Earned Income Tax Credit, can result in a refund even if you had no tax withheld or had no tax liability. For example, a worker with no tax liability who qualifies for a $1,500 refundable credit would receive a $1,500 refund check from the IRS.
What happens if my tax credit exceeds the amount of tax I owe?
For non-refundable credits, the excess is lost. For refundable credits, the IRS will issue a refund for the difference. Some credits, like the Child Tax Credit, have both a non-refundable and a refundable portion. If your total credit exceeds your tax liability, the non-refundable part eliminates your tax, and the refundable part is sent to you as a refund, up to the credit’s refundable limit.
Final Thoughts
Tax credits are one of the most powerful tools for reducing your tax bill or increasing your refund. Whether you are a parent, a student, a low-income worker, or someone saving for retirement, there is likely a credit designed to benefit you. Because eligibility rules, income limits, and credit amounts change each year, it pays to check the latest IRS guidelines or use a current tax preparation tool. Many credits are unclaimed because taxpayers underestimate their eligibility. By understanding the difference between refundable and non-refundable credits, knowing which credits apply to your situation, and filing the correct forms, you can take full advantage of the tax savings available to you
