personal income tax rates" Bankrate.com
A. Federal tax liability is calculated by taking the $60,000 salary
and subtracting the $3050 exemption and $5,000 itemized deduction.
The short-term capital gain and the interest on bonds are taxed at
ordinary income rates, so they are added to the result. This results
in a net ordinary income of $57,950.
We calculate the tax using the personal income tax rates from the
table at the Bankrate.com web site. The tax on the first $7,000 is at
10%, the next $21,400 is at 15%, and the remaining $29,550 is at 25%.
The tax is $11,297.50.
The municipal bonds are tax free. The dividends in long-term capital
gain are both taxed at a rate of 15%. The $10,000 in dividends yields
$1500 in taxes, and the $13,000 long-term capital gain yields $1950 in
taxes.
So, in total, the Federal tax liability is $14,747.50.
B. The marginal rate of taxation is 25% (an additional dollar of
ordinary income will be taxed at 25%). The average rate is calculated
by taking the total tax divided by the total income. The total income
is the sum of the salary, dividends, interest on bonds, interest on
municipal bonds, long-term capital gain, and short-term capital gain,
which together total $99,000. $14,747.50 divided by $99,000 a yields
an average tax rate of 14.9%.
C. The municipal bond would be a better investment because the
corporate bonds have an after-tax yield of only 8 1/4%, whereas the
municipal bond has an after-tax yield of 9%.
D. The marginal tax rate where one is indifferent would be the one
that causes the corporate bond to have the same after-tax yield as the
municipal bond.
0.09% = 0.11% (1 - Marginal Tax Rate)
Marginal Tax Rate = 18.18%
