Will my parents directly paying the IRS for my large tax bill affect me filing Ch 7 for large credit card debt?

I think the key is to disclose this to your bankruptcy attorney, I do not think this should be a major problem, you just want to discuss this with your bankruptcy attorney and make sure it's properly described somewhere on your bankruptcy schedules. I do not think it should impair your bankruptcy, especially when you are not paying money to your parents prior to filing, but it is good to discuss this with your bankruptcy attorney.

Yes you need to discuss this with your bankruptcy attorney. Probably the best strategy would be to file the bankruptcy first and deal with the IRS later.

I would be happy to discuss this with you by email

I agree with the responses you have received. While it should not present a problem, if it is only going to amount to a few additional dollars in penalty, I would get the bankruptcy done first. The attorney filing your case should address this more carefully. There is too much at stake to move carelessly.
