A tax credit reduces the tax you otherwise owe, generally dollar for dollar. The difference between a refundable credit and a nonrefundable credit is what happens after tax reaches zero.12 This guide explains that mechanics in plain language. It is education only, not tax, legal or investment advice. Credit names, amounts and phaseouts change by year — check current IRS tables and publications before you rely on any figure.
Shared starting point
Both refundable and nonrefundable credits are subtracted from tax due.13 For the broader contrast between credits and deductions (income reduction vs tax reduction), see tax credit vs tax deduction. Transferability — whether a credit can be sold or assigned to someone else — is a separate idea; see what is a transferable tax credit.
Nonrefundable credits
Most tax credits are nonrefundable: they can reduce tax down to $0, but any leftover credit generally does not turn into a cash refund.12 Some nonrefundable credits have their own carryforward or carryback rules written into the statute or form instructions; those rules are credit-specific. This guide does not invent carry rules — read the form instructions for the credit you are looking at.
Refundable credits
A refundable tax credit is one you can receive as a refund even if you do not owe any tax.1 After the credit reduces tax to zero, any remaining refundable amount can be paid out. The IRS notes that people who are not required to file may still want to file if they might qualify for refundable credits, because filing is how those amounts are claimed.14 That is a description of IRS filing guidance, not a promise that any person will receive a refund.
Partially refundable credits
Some credits have both a nonrefundable piece and a refundable piece. The IRS refundable-credits page lists examples at a high level, including the Child Tax Credit (with a refundable Additional Child Tax Credit portion), the American Opportunity Tax Credit, and the Adoption Credit.1 Exact dollar caps and income limits are year- specific — see current IRS tables on those program pages rather than memorizing numbers from this article.

Common questions
What is the difference between refundable and nonrefundable credits?
Both reduce tax. A nonrefundable credit generally stops at $0 of tax. A refundable credit can continue past $0 and be paid as a refund if the rules for that credit are met.12
Can a nonrefundable credit create a refund?
Generally no, once tax is already $0. Some credits have separate carryforward rules; confirm the current form instructions for that credit. Do not assume leftover nonrefundable credit becomes cash.
Why does the IRS say some people should file even if they do not owe?
Because filing can be the only way to claim a refundable credit or recover withheld tax, when the person is eligible.145 Eligibility is personal; this article cannot tell you whether to file.
Should I use this article to file my return?
No. This is educational background only. Confirm current-year rules and your own facts with a qualified professional and the IRS pages linked above.
