You can e-file your taxes. And it makes things easier on the IRS because they don't have to open an envelope and enter the data from your form into a computer manually, which is exactly why the Old Grouch refuses to do this until they threaten to throw my ass in jail or garnish my paycheck if I don't, which they probably will sooner or later. I don't use their peel-off address labels either. And I use a 5-digit zip code. The Old Grouch finally got through the gauntlet of paperwork and felt pretty good about not having to pay as much as I thought I would.
Politicians are the sneakiest bastards in the world.
I hate the IRS but have to admit that they are good at what they do. Then they overcharge us. The Old Grouch used to feel good when I got a tax refund. I used to consider my paycheck as the amount I brought home and didn't think about the rest.
