Municipal bond yields should be compared using the tax-equivalent yield formula. In the 32% federal bracket, a 3.1% muni yield equals a 4.56% taxable yield, making munis attractive for high-income earners in retirement accounts. For more on this topic, see Financial Independence Milestones.

This is exactly what I needed to hear. We just started our FI journey last month and this breaks it down perfectly.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?
