Years ago in presenting a Junior Achievement math program to 8th graders, I was surprised to know that the majority knew the answer as to when an individual's income tax return is due. April 15 has certainly become a part of our "tax culture." I don't think this date will change as part of any tax reform efforts, but you never know. Certainly, there are likely a few individuals still waiting for K-1s and corrected 1099s today and will struggle to estimate their tax due today.
Okay, on to the nostalgia part. I've been a fan of Irving Berlin since high school. One of the hundreds of songs he wrote was one commissioned by the government in the 1940s when the number of individuals subject to income tax grew tremendously (tied to WWII funding needs). The song is "I Paid My Income Tax Today." I've found online recordings by Gene Autry and Danny Kaye. Enjoy!
