Here's a list of all the federal income tax brackets in US history:sorry to be soooooo late....but is it true?
I heard a report that FDR dealt a tax of 100% for all income over 25,000dollars

Around the end of FDR's term, the tax rate on income above $25k/year was 51%. In today's inflation-adjusted dollars, $25k/year would be about $370k/year.
FDR's top tax rate was 81% for any money made over $5 million per year, which translates into about $73 million per year today.
He didn't have the highest tax bracket, though. Under Dwight Eisenhower (a Republican), the top rax rate was 91% on incomes over $200k. Today that would translate into 91% tax on all money made beyond $1.7 million per year or so.
