re: Anybody have to verify their identity for the IRS?

This is dumb. They make you verify your identity to make a payment. The fact is the IRS is very disorganized and makes mistakes.

I’m all for adjusting your withholdings and paying the difference when you file, that’s your choice. Penalties are typically negligible or non existent. But don’t let double standards get in your way, there should be ID controls in tax returns just like there should be with voting. Its a self reporting system and there should be no opportunity for fraud.
