Did you know?
– The first US federal income tax was introduced in 1861 to finance Civil War expenses, imposing a 3% tax on income above $800. In 1913, the 16th Amendment made the federal income tax system official.
In 1913, it was only 400 pages long; today, it is over 70,000 pages long. Imagine 60 Bibles stacked on top of each other – that’s the size of the Federal Tax Code alone – apart from state obligations!
– Fraudulent tax returns are more common than you might think. For example, Raudel Sandoval of Placentia (Orange County, CA) was recently convicted of preparing more than 400 fraudulent tax returns for his clients between 2015 and 2018.
