True, but I didn't see that specified so didn't assume so. That said, outside our IRA's we have munis & KY ones only. We use the Dupree KY specific funds to some degree & in both cases avoid KY income taxes too.
Kentucky has the second worst unfunded pension liability in the nation. Until that situation is improved I am limiting my exposure to Kentucky bonds. I can also do without exposure to the Yum Center bonds. Buying other states' munis still gets you federal tax free status. I am just giving up on saving on Kentucky income tax. I am probably being too conservative though.
