No. Tax withholding has nothing to do with how much credit you are eligible for. What I was saying is that your credit would offset the tax liability and so you would get back all the withholding. Your credits would pay your taxes and you would get a refund of your $8,000 of withholding. The credits you get will be equal to and limited by your tax liability. The exception would be self employment taxes if you are self employed. Credits cannot offset self employment taxes.
