Frequently Asked Questions

It is the yield a taxable bond must offer to equal the after-tax return of a tax-exempt municipal bond, based on your marginal tax bracket.

Investors in higher tax brackets (24%+) benefit most because the tax exemption provides a larger effective yield advantage.

Yes. If your state exempts in-state muni bond income, toggling on state tax in our calculator shows an even higher tax-equivalent yield.

Generally no. Tax-advantaged accounts already shelter income from taxes, so the muni bond tax benefit is wasted there.

At a 0% rate, TEY equals the bond nominal yield, meaning tax-free bonds offer no advantage over taxable bonds.
