I started a thread on this a few years ago, asking what happens if you just blow them off or what rights you have during an audit. Seems to me, the worst they can do, absent your cooperation, is decide to redo your taxes for the year(s) in question for you, and then it'd be on you to dispute them. But why would you ever help them when they're trying to build a case against you? I'm not aware of any special powers they have when it comes to search and seizure. They can ask for consent, just like your local cops or even nextdoor neighbor can. You don't have to give it and they'd need more than your refusal to constitute PC for a warrant. Or is there a current audit going on and this "visit" is a part of that?
