Answers to common questions

Which credits does the 10-year ban apply to?
The 10-year ban applies to certain credits we denied in an audit of your tax return and determined your claim for the credits was due to fraud.  The credits may include Earned Income Tax Credit, American Opportunity Tax Credit, Child Tax Credit, Additional Child Tax Credit or Credit for Other Dependents.

What do I need to do to claim the credits in the future?
If, after 10 years, you want to claim the credits, you must complete and attach a Form 8862, Information to Claim Certain Credits After Disallowance (PDF), to your return.

What do I need to do if I disagree with the 10-year ban?
You may request a reconsideration of the audit.  In your request, send us proof you are entitled to the credits for the audited year, or proof your claim for the credits wasn’t due to fraud. 

How do I get a Form 8862?
Visit Forms and Publications or call 800-TAX-FORM (800-829-3676) for forms, instructions, and publications.
