Additionally, if you are eligible to receive the Child Tax Credit based on the dependents you have entered on your tax return, you will automatically receive the credit using tax preparation software. You will not be able to remove the credit.
The only way to do what you want to do is to NOT claim any eligible children for CTC as dependents on your tax return. Then if you receive the refund advance based on your federal tax refund, without claiming dependents, you can amend your tax return and add the dependents and the Child Tax Credit will be included in the amended return, if you are eligible.
Also, if you are eligible for the Earned Income Tax Credit and are receiving a refund, the refund will be held until mid-February. The EITC cannot be removed from your tax return if you are eligible.
