But if it is irrelevant why do you fear that you will need to provide it? I’m honestly at a loss. Do you mean something such as to whom do you send wire transfers, or which specific companies you have on your portfolio? Or more like having an account together with someone? Something else?

Why would I want to give private data which is irrelevant to the IRS to the IRS? I'm honestly at a loss as to why you think that position is unreasonable.

My data is my data. I truthfully and completely provide to people, companies, and government agencies who have a need to hold or process only that data is required.

I also have a group of advisors whom I trust entirely and I share data more openly so they can help me plan and execute better.

What specific positions (or even total account value) I hold in my various accounts is not required for the IRS to compute my taxes. My advisors on the other hand I willingly give that information so they can give me better advice/guidance.

My tax preparer knows what is required for the IRS and ensures they get that correctl, completely, and precisely nothing more. There's no way the IRS could find all the data that's relevant to my taxes without getting any not relevant data without some expert actor doing that filtering (and from a comparative advantage perspective, I want to pay someone more expert than me to do that)

Ok, that's interesting. I don't follow this:

> What specific positions (or even total account value) I hold in my various accounts is not required for the IRS to compute my taxes.

How can they compute your financial gains without knowing your portfolio changes? (sorry I'm not american and thus my preconceptions of how do you do taxes are weird for you).
