So I don't just file a return for the prior calendar year with the IRS, I have to go back and re-file the
past returns changed by that return.
...and if those past years contain factors that carry backwards or forwards into other years that have
already been filed, and the amendment alters those factors, then *those* years must
also be amended and refiled.
*Whew!* I have tax years that had already been amended four times--before this year. (Which means
it's "five times" now.)
But, as I'd said, this year broke all my past tax-filing records. The ping-pong ball progress of tax
adjustments bouncing forward and backwards between tax years hit a total of twelve past returns
that needed to be revised and refiled.
Fun, fun. But, then, a lot of people like solving sudoku puzzles. This is kind of similar, just
a whole lot bigger.
...and has substantial penalties if you ever make a mistake.
