“Hopefully, the IRS will issue guidance in the future that reaches the same conclusion.”

From Wikipedia: Hopefully is an adverb which means "in a hopeful manner" or, when used as a disjunct, "it is hoped". Its use as a disjunct has prompted controversy among advocates of linguistic purism or linguistic prescription. Merriam-Webster says the disjunct sense of hopefully dates to the early 18th century and had been in fairly widespread use since at least the 1930s. Objection to this sense of the word only became widespread in the 1960s. Merriam-Webster says that this usage is "entirely standard". Before 2012, the AP Stylebook proscribed the use of "hopefully" as a disjunct.

So, I won’t complain about hopefully. We don’t yet have an IRS commissioner, so the mental image of him looking hopeful while making an announcement is difficult to conjure.

However, when else would IRS issue guidance, if not “in the future” ? I assume the author is not being paid by the word. Maybe I shouldn’t. In any case, I will defend my position that exclusions should not be added in to income on a return only to be subtracted out. Practitioners aren’t going to charge for this? Their clients are being bamboozled.
