Mr. Klotz answered one question about the “Big Brother Expands Reach” article in the Bond Investors’ Forum, but his response has raised another question for me. Here is the last paragraph from Mr. Klotz’s answer: “Incidentally, there is a method to this madness. Although the interest is not taxable, certain levels of tax-free income can reduce other benefits you receive, such as Social Security.” My question is: How can I determine if the amount of tax-free interest I earn is at a level that will reduce other benefits?
