Answer:
10.23%
Step-by-step explanation:
Formula for computation of equivalent taxable yield is r = rm/1-t. Where the tax rate is t, rm is Yield on municipal bond and r is Tax equivalent yield
r = rm/1-t
r = 6.75% / 1 - 34%
r = 6.75% / 0.66%
r = 10.22727272727273%
r = 10.23%
So, the equivalent taxable yield to a taxpayer in a combined federal plus state 34% tax bracket is 10.23%.
