Okay; no one is sending anything. This is a forum on the web.

"I mean for instance if someone asked you if the expenses you pay with a tax free PPP grant are deductible, this process of linking to general guidance would lead to the wrong answer."

Only if you find the wrong links, then share them. And everything has been subject to change, so that is another reason to provide Current links (as of this date and the work being done today). I ignore articles that are not dated, for that very reason.

"And if a grant is for capital replacement, it is not subject to self employment tax despite all the links you've sent."

Oh, now you need to provide this evidence. Because only specific provisions exist, such as grants for upgrading HVAC that fall under CARES Act because they were issued for that purpose.

"And the most specific cites you sent related to corporations in which S/E tax is moot."

Only if you don't believe it relates to business income.

If you need to, you can ask the IRS yourself.
