As of Nov 4, 2026, ETFIQ covers 154 municipal bond ETFs, with a median fee of 0.25%, and 146 bond funds own 90% or more in municipal bonds.

### In plain words

A municipal bond ETF owns bonds from states, cities and other local bodies. The interest on many is free of federal income tax, which is why they exist, and its value depends on each investor’s situation.

ETFIQ counts 154 municipal funds at a median fee of 0.25%, national and single-state, short to long. 146 bond funds own 90% or more in municipal bonds, read from filings. Yield is not comparable with a taxable bond fund until tax is counted, so ETFIQ states it as paid and gives no tax advice.

### Questions

Is the income from a muni fund tax free? Often free of federal income tax, not always. It depends on the bonds and on you. This is not tax advice.

What is the difference between national and state funds? A national fund owns bonds from many states. A state fund owns one state’s bonds.

How does ETFIQ read a fund’s bonds? From its latest N-PORT filing, bond by bond.
