Exhibit (a)(5)(v)

Why am I receiving this letter?

You are receiving this letter because you hold shares in BlackRock Municipal Income Fund, Inc. (“MUI” or the “Fund”). MUI will be converting from an exchange-listed closed-end fund to an unlisted interval fund (the “Conversion”). The Conversion is currently expected to occur in the first quarter of 2025.

How will the interval fund differ from MUI?

MUI shareholders are currently able to sell their shares on the NYSE at market price on any day that the NYSE is open for trading. The market price for Fund shares can be higher (at a premium to) or lower (at a discount to) than the Fund’s net asset value (“NAV”).

Following the Conversion, the Fund’s shares will no longer trade on a stock exchange. Instead, the Fund will provide periodic liquidity by conducting quarterly offers to repurchase between 5% and 25% of the Fund’s outstanding shares at NAV.

Shareholders may face reduced liquidity following the Conversion, but may benefit from the ability to have their shares repurchased at NAV (as opposed to potentially having to sell shares at a discount on an exchange). In addition, the Fund will be continuously offered, which will provide shareholders with the ability to purchase additional shares of the Fund at NAV (less any applicable sales load).

When will the conversion take place?

The Conversion is currently expected to occur in the first quarter of 2025. After converting, shareholders will have limited liquidity via quarterly repurchase offers.

What are my options to sell if I do not want to hold the interval fund?
