I am interested in two municipal ETF’s for my IRA retirement account; NXJ (New Jersey Municipal Bond Fund) and NRK (New York Municipal Bond Fund). I live in New Jersey and NXJ currently has a distribution yield of 5%. If I buy NXJ, will I get a tax exemption on the distributions received from the fund? Would it be on the state and federal capital gains? How about NRK, a New York municipal fund. Would I still receive a tax exemption?
