Nathan Reiff at Investopedia asked me how to choose between municipal and corporate bonds inside a retirement portfolio. My answer was that munis versus corporates is not a contest. It is a question of what the money is for and where it lives.
They solve different problems. Municipal bonds trade yield for tax efficiency; the interest is generally free of federal tax and sometimes state tax. Corporate bonds trade safety for income; they pay more because the credit risk is higher. Neither one wins on its own.
The mistake I see most often is chasing the tax break without checking the account. I once reviewed a portfolio holding a large muni ladder inside an IRA. The investor was paying for a tax advantage that does not exist inside a tax-deferred account, and it was quietly costing real money every year in lower yield.
So the first question is not which bond yields more. A taxable account for someone in a higher bracket may favor munis. A tax-deferred account built for income may be where corporates earn their spot. Laddering maturities across both keeps you from feeling locked in if rates move.
Many retirees spent their careers ignoring fixed income, and then it suddenly matters a great deal. Getting the account location right is the easy win most of them are missing.
