California residents in the top tax bracket pay a combined rate above 50% on investment income: 37% federal, 13.3% state, plus the 3.8% net investment income tax. That math has always made municipal bonds relevant. What's different now is the yield.
High-quality California munis are offering tax-equivalent yields north of 7%. For context, that's competitive with investment-grade corporate bonds on a pre-tax basis, but without the federal or state tax drag.
The income case is straightforward. A 4% tax-free yield at a 54% combined marginal rate translates to roughly 8.7% pre-tax equivalent. That's a meaningful after-tax advantage over taxable alternatives, particularly for portfolios generating six figures in annual income.
The portfolio case is less obvious but may matter more right now. Treasuries have struggled as equity hedges when inflation is elevated. In a portfolio that needs something to hold up when stocks sell off, high-quality munis with shorter durations are doing some of that work, especially with rate uncertainty around the Fed chair transition.
One note: the double tax exemption applies to California residents holding California-issued munis. If you're in another high-tax state like New York, you'd still owe state tax on the income, but the federal exemption alone keeps the after-tax yield well ahead of most taxable alternatives.
What's the catch? Duration risk. If rates move higher, longer-dated munis lose value like any fixed income instrument. Credit quality varies. California's general obligation bonds carry strong ratings, but not every issuer in the state does. And liquidity in the muni market is thinner than Treasuries, so selling in a hurry can mean a wider bid-ask spread.
The window is partly a function of supply dynamics and rate levels that won't stay static. Whether it warrants a larger allocation depends on your overall tax picture and how much fixed income you're already holding.
