Thank you for your response but I still say that the Credit whether it is refundable or not does affect my total tax liability and my effective tax rate.
Let's say that I have 3 children and my total tax is 15,000 without the credit.
Those three kids get me 9000 (all over 6). Now the total tax liability is only 6000.
Without those 3 kids, I would owe 15,000. It doesn't make a difference fully refundable or not.
Suppose My total tax liability was 8000 without the credit. Non refundable , my tax would be 0 and effective tax rate 0.00%. Refundable and I would get a check for 1000 and my effective tax would be negative. It all still effects my ultimate tax liability.
