Does a muni bond fund have to list all the states?

[robtm]

No. you use RIC as the state and list the total muni income you received from the fund.

[Hal_Al]

No. Assume that the entire amount is taxable by your state.

But many will voluntarily provide you a breakdown list. It does not come withe your 1099-Div, but is usually available at Mutual Fund Co. web site.
