Although I messed up my Treasury Bill Ladder by switching to 6-month T-Bills, they continue to be a pretty good cash investment alternative for those people in states with high income taxes, as they are exempt from such taxes. For example, the most recent 6-month T-Bill paid a rate of 4.754%. Using my Equivalent Rate Calculator, and a federal tax rate of 25% and state tax rate of 9%, that’s the equivalent of a regular 6-month bank CD paying 5.40%. The 4-week T-bill equivalent rate is 5.07%.
