Answers to Common Questions
I lost the return envelope. Where do I mail my worksheet and Form 8812?
Mail the worksheet and form to the address listed on the top left corner of the worksheet. This is the IRS center that handles cases in your region, so it’s important you send it there to avoid potential delays in processing.
What’s the difference between the "Child Tax Credit" and the "Additional Child Tax Credit"? Can I qualify for both?
The Child Tax Credit is for people who have a qualifying child. The maximum amount you can claim is $1000 for each qualifying child. The Additional Child Tax Credit is for individuals who receive less than the full amount of Child Tax Credit. You may qualify for both the Child Tax Credit and the Additional Child Tax Credit.
I sent you my worksheet and form. When will I get the refund?
We’ll review your form and worksheet and make a determination for your credit. If we deny your credit, we’ll send you a letter explaining why, but if you owe no other amount, you should receive your refund in 8 to 10 weeks. If you don't hear from us after 8 to 10 weeks, call our "Where’s My Refund?" toll free line at 1-800-829-1954 to check on the status of your refund.
My son/daughter is turning 18 this year. Can I still get the Additional Child Tax Credit?
No. Your child must be under age 17 at the end of 2009 to qualify for both the Child Tax Credit and the Additional Child Tax Credit.
Tips for next year
If you have dependent children, remember to claim the Additional Child Tax Credit the next time your file your 1040 or 1040A tax return. To do this, complete and attach Form 1040 Schedule 8812 to your return.
Consider filing your taxes electronically. Filing online can help you avoid mistakes and find credits and deductions that you may qualify for. In many cases you can file for free. Learn more about e-file.
