Answer:
A. = (15% X $2M) + (21% X $2M) = $720,000. Since there is no mechanism for mitigating double taxation, the branch profit will be taxed on the to tax rate of 15% and 21% which is $300,000 and $420,000.
B. The total tax for $2m branch profit if US corporations can remove foreign based profit from US taxation will be just the 15% x $2m = $300,000.
C.If they are allowed to take deductions for foreign income taxes, the total tax on the $2m branch profit will be (21% -15%) x $2m = $120,000.
