It’s April 15 - Are Your Taxes Done?

State-of-the-art systems at internalrevenueservice are waiting to process your returns!

While punch cards and tape drives seem archaic now, they were a “new dimension” in data processing and tax administration at the time of this IRS educational film, “Right on the Button,” from the late 1960s.

Now, go finish those taxes!
