The PA-40ES(I) forms are personalized, so it makes a little sense that you are supposed to use those when you have them. It makes less sense that you can't get the PA-40ESR(I) online, and that the PA-40ES(I) says "photocopies or other facsimiles of this form are not acceptable."
It turns out that the reason for these two facts is that the forms are color-coded. I guess it makes sense that having the forms color-coded would be at least a weak reason for those restrictions, but I'm not convinced that that's such a good thing.
The point of all this exposition is that it was time to file estimated taxes yesterday, but I was unable to find my PA-40ES(I) forms. I believed that they were somewhere in the paper-storm of the computer room, but they weren't in the pile where I expected them to be.
So I did the first pass of cleaning the room, that of sorting all the paper in the room into piles--trash, CDs, software, Lori's stuff, my stuff.
Just doing this made a big difference to the appearance of the room. There are obvious next improvements that I didn't get to, like throwing away the trash piles, but already the room looks much better.
And I found the forms that I needed.
