I don't know that I trust that site, since it had this to say...
The top tax rate is lowered to 25 percent - the lowest top rate in the eight decades since World War I.
That would make WWI happen in 1845. We had no income tax until 1862, and it only lasted til 1872, then the gov tried again in 1894 and 1895, temporarily gave up when the Sups said it wasn't Constitutional, so they slapped the 16th Amendment on in 1913 and started taxing us all to hell and gone... for the next hundred years.
