Quote from @Caleb Rehg: Don't bother giving them much.

Especially in Partnership land - the complexities of amending a partnership return are not cheap, and if you have 20 partners that now need to all amend their returns to get their 100% bonus depreciation later, that is a lot of compliance fees just for not wanting to extend.If you just file as is with the 80% rules, you can always amend later if/when it gets bumped to 100%, so that isn't a significant problem, just an extra step.What I would not recommend doing is filing as 80%, and then not bothering to fix it if it goes to 100%.

If I were a guest and you made me enter my email for internet access, it would bother me.
