A tax credit cuts your tax bill dollar for dollar. A $1,000 credit removes $1,000 of tax. That makes credits far more valuable than deductions of the same size, which only reduce the income you are taxed on.
The distinction that decides whether money reaches your bank account is a different one: whether the credit is refundable.
Refundable and nonrefundable
- A nonrefundable credit can reduce your tax to zero and stops there. If the credit is larger than your tax, the excess is lost.
- A refundable credit can be paid to you as a refund even if you owe no tax at all.
This is why two households with the same credits can see completely different outcomes. A working household with little or no tax liability gets nothing from a nonrefundable credit and can receive real money from a refundable one. It is also why people with low tax liability sometimes skip filing and lose money they were entitled to: a refundable credit only reaches you if a return is filed.
The two that reach the most households
For tax year 2025:
- Child Tax Credit — worth up to $2,200 per qualifying child. If your federal income tax liability is small or zero, part of it may still come to you through the Additional Child Tax Credit, worth up to $1,700 per qualifying child depending on your income. That refundable portion is the part that matters most to lower-income filers.
- Earned Income Tax Credit — a refundable credit for people who work and have earned income below a limit that changes each year. For 2025 the maximum EITC is $8,046 for taxpayers with three or more qualifying children; for tax year 2026 that maximum rises to $8,231.
Both have detailed qualifying rules — relationship, age, residency and support tests for a child; earned income and investment income limits for the EITC. Those rules are where claims get denied, not the arithmetic.
The education credits, and why they are not interchangeable
Two credits cover higher education costs, and the difference between them is exactly the refundable-versus-nonrefundable distinction above:
- American Opportunity Tax Credit — up to $2,500 for tuition, certain required fees and course materials paid during the year. Up to 40% of it is refundable, meaning up to $1,000 can come back to you even if it exceeds the tax you owe.
- Lifetime Learning Credit — up to $2,000 per return regardless of how many students you paid expenses for. It is nonrefundable: it reduces tax to zero and no further.
A household with modest tax liability and a student in the family can therefore receive money from one of these and nothing from the other. Which one you are eligible for depends on the student's year of study and other conditions — it is not a choice you simply make.
The ITIN complication, which is common here
Credit eligibility can depend on what kind of taxpayer identification number appears on the return, and for which person on it. That is not a footnote in South Florida, where mixed-status households are ordinary.
Two practical points. First, an ITIN that has not been used on a federal return in three consecutive years becomes inactive, and an inactive ITIN on a return can cost you credits you actually qualified for. Second, renewal is not automatic — it takes a Form W-7, and it takes time. If anyone on your return files with an ITIN, check its status before filing season rather than during it. We handle that as part of ITIN applications and renewals.
Why the amounts here have years attached
Credit amounts, income limits and phase-out ranges are adjusted regularly, and several were changed by legislation taking effect in 2025. An article that quotes a credit amount without saying which year it belongs to is worse than useless — it looks authoritative and is wrong by the time you read it.
So: every figure above is tax year 2025 unless labelled otherwise, and comes from IRS guidance current as of July 2026. Before you rely on any of them for a return, confirm the year you are actually filing for.
Find out which credits you actually qualify for
Most people do not lose credits by calculating them wrong. They lose them by not knowing a credit existed, or by having a return rejected over an identification number. If you have children, income from work below the EITC limits, or anyone on your return filing with an ITIN, a review before you file is worth more than an amendment after.
