On September 24, 2025, accounting industry groups including the Minnesota Society of CPAs gathered at the Target Center in Minneapolis to create the longest line of calculators.1 Their world record total added up to 1,094.
By our math that’s enough calculators to give one to every attendee at one of our tax update seminars in Anaheim, historically Spidell’s largest in-person location. But even that falls well short of the world record for the largest taxation lesson. In 2018, 3,378 people attended a class taught by the Institute of Company Secretaries of India.2
Some other sums
In 2011, General Electric filed a 57,000-page tax return.3
In 2012, the IRS paid $104 million, the largest amount ever to a single whistleblower, to Brad Birkenfeld in the UBS tax evasion case.4
In 2017, Florida man Ramon Blanchett received a tax refund of $980,000.5
What do your accomplishments add up to?
Do you have any tax-related triumphs that are worthy of an entry in the record books? The longest time spent on hold with the FTB or IRS in a single phone call? The most repeated requests for any one client to send you their documents in a tax season (their last tax season with you, presumably)? We don’t have any sway with Guiness Book of World Records, but send us an e-mail and your feat might show up in a future Tax Season Tribune.
