Someone once asked behavioral economist Dan Ariely what percentage of Americans cheat on their income taxes. Dan’s reply:
I’m not sure, but it’s clearly a large amount: Pew Research estimated that the IRS lost about $270 billion dollars for tax “underreporting” in 2010. I tend to agree with Will Rogers, who once said, “The income tax has made liars out of more Americans than golf.”
Taxes don’t just tempt many Americans to cheat. They also kill us. A 2012 paper by Donald Redelmeier and Christopher Yarnell published in the Journal of The American Medical Association found that over the past 30 years, fatal accidents increase by about 6% on April 15 compared to standard days. The authors chalk this up to stress. They also show that this increase doesn’t hold for people at retirement age (who, presumably, aren’t that stressed about taxes), has increased over time (suggesting we’ve been under more stress as U.S. taxes have grown more complex) and is particularly large for those of us on the West Coast (where state taxes are particularly high).
Of course, these two findings—increased dishonesty and increased stress—could be linked. So this tax season, please try to be safe when filling out and delivering your 1040s.
