Answer:
a) Chuck's total taxable income = $119,480
since Chuck is a single filer, his marginal tax rate for 2020 is 24%, and his tax liability for ordinary income = $14,605.50 + [24% x ($119,480 - $85,525)] = $14,605.50 + (24% x $33,955) = $22,754.70
the interest earned on municipal bonds is not taxed.
b) Chuck's total taxable income = $38,520
since Chuck is a single filer, his marginal tax rate for 2020 is 12%, and his tax liability for ordinary income = $987.50 + [12% x ($38,520 - $9,875)] = $987.50 + (12% x $28,645) = $4,424.90
the interest earned on municipal bonds is not taxed.
