Frequently asked questions

What is Earned Income Credit (EIC)?

The EIC is a credit for certain people who work and have earned income. The credit may give you a refund even if you do not owe any tax.

If I'm eligible for the credit, when will I receive my refund?

We’ll mail you a refund check in 6-8 weeks if you don’t owe tax or other debts we’re required to collect. If we deny the credit, we’ll send you a letter of explanation. If you don't hear from us after 8 weeks, you can call our toll-free line at 800-829-0922 to check the status.


Tips for next year

  • Claim the credit if you are eligible.
  • You can ask us to figure the earned income credit for you by writing "EIC" on the EIC line, complete Schedule EIC, and attach it to your return. If you qualify for the credit, we’ll calculate it for you.
  • Write "NO" on the EIC line if you don't want or you don't qualify for the credit.
