You'll find the self-explanatory files below which have not only the tax rate
schedules for the 99 years of Federal Income Tax, but the actual taxes computed.

I found the following links to be tremendous resources. The first one saved me the trouble of trying to get the information from
the IRS directly or various libraries etc. In fact, if the first website had actually COMPUTED the actual tax due, I wouldn't have had any work at all to do!
And since it's now 2012 and not 2011, I thought it would be appropriate to INFLATION-ADJUST to 2012 and so I used the second website below to find the appropriate
yearly inflation-adjustment multiplier. The third one is the actual 1954 table from the IRS and it's the "real McCoy"

[ U.S. Federal Individual Income Tax Rates History, 1913-2011 (Nominal and Inflation-Adjusted Brackets) | CPI Inflation Calculator | The actual original 1954 IRS tax rate schedule ]
[ Statistics of Income ... 1954 ... Individual Income Tax Returns for 1954 ... on IRS Website ... go to page 114 and find above tax rate schedule ]
