A newly issued bond pays its coupons once a year. Its coupon rate is 4.6%, its maturity is 10 years, and its yield to maturity is 7.6%.

If you sell the bond after one year when its yield is 6.6%, taxes will you owe if the tax rate on interest income is 40% and the tax rate on capital gains income is 30% are below. The bond is subject to original-issue discount (OID) tax treatment.

- tax on interest income - $18.40

- tax on capital gain - $21.73
