Just realized I didn't answer your questions:
1. What about those taxes Delaware seems to have (1-A to 1-C)? Do they not apply to Non-Resident Aliens?
If you do not trigger state nexus 1B and 1C do not apply to you. 1A is actually Delaware's version of Annual Report Fee, which is collected by other states. The Franchise tax for DE LLC is $300 every year.
2. Wyoming seems to give you more
privacy, sharing less than Delaware with the respective state authorities (2-D to 2-G). Isn't 2-F given away by form 5472 in any case?
You got 2D 2E wrong, it is not listed in DE state records.
As for 2G, i honestly don't know the question to this. but I assume both states could be possible.
Form 5472 will expose you anyway to the IRS, if your sole objective is to run away from IRS, its pretty impossible.
3. Was probably bad wording from one of the sources, but Wyoming seems to give you an extra year of proper privacy (3-A and 3-B)?
No it is not an extra year. It is because Delaware has a fixed date for annual report (franchise tax) for all LLCs, regardless when you are registered. But for Wyoming LLCs, your annual report is due at the month next year of your formation month. e.g. you registered an LLC on 15th of June 2022, your annual report deadline is 1st of June 2023
4. The 3 of the 4 sources used had Nevada too, and 5-D seemed to put both DE and WY in a bette rplace than Nevada. But by many accounts, WY is still far from great about getting somebody to open a
bank account for you as a NRA...
Forget about Nevada. Just pick Wyoming unless you want to convert your LLC to a C-Corporation to raise VC investments, then you pick Delaware.
