"Nothing's as certain as death and taxes!" my father used to say. He was usually just joking around at tax time. But there's the truth of it that makes the statement (slightly) amusing.
As it turns out, Reader Dear, I've discovered one can get an extension on both! Each has its deadline (better known as flatline in the case of death) which, with a little maneuvering (or all kinds of inconveniences and miseries) can be pushed further into the future!
Our accountant will spend some time in assessing our taxes due; but, no matter how capable, precise and meticulous, the bottom line will not be the exact same figure as each of a dozen other accountants would give us, were we to present them with our (semi-organized) mess of papers.*
*It's the nature of the U.S. tax codes, Reader Dear! Seventy-thousand pages of federal tax codes yield various figured-out figures!
Which proves my own assertion, Reader Dear, regarding death and taxes: "Nothing's as certain as uncertainty!"
