What is Refundable Credit?
A refundable credit can pay out even when it's bigger than your tax bill — you get the leftover back as a refund.
How it works
First it wipes out your tax; then any excess is refunded to you in cash. That's what separates it from a nonrefundable credit, which can only take your tax down to zero. Refundable credits are how many lower-income families receive money back beyond what they paid in.
A quick example
What people get wrong
The Earned Income Tax Credit and the refundable portion of the Child Tax Credit are the big ones — and they're among the most-missed. If your income is modest, check eligibility every year.
