if youre audited, does the IRS look at your credit card accounts?

Extremely unlikely. Most audits are over specific items. It'd be very unusual for them to do a full-blown criminal investigation-type audit where they'd go to that level of detail.

Yeah, if you've never filed income tax, and you live like a multi-millionaire, and when they confront you and you still refuse to acknowledge any income, etc. They would then be forced to do a criminal investigation and then they'd go thru your finances with a fine-toothed comb.
