One principle of U.S. taxation is that double taxation should be avoided, that is, if a U.S. company has already paid the taxes abroad, it should pay only taxes in the U.S. to bring the overall rate up to the U.S. rate. Thus foreign taxes already paid are subtracted from the U.S. tax as indicated in line 7,8,9, and 14. However, the tax credit does not include all taxes paid abroad. It includes all the withholding taxes but only a fraction of the total income tax of abroad. The latter is known as the deemed tax and is calculated by multiplying the tax paid abroad by the proportion of after-tax that is remitted as dividends. In the above example, the income tax abroad was $250000, but since only half of the after-tax earnings were remitted as dividends, the deemed tax was 1/2*$250000=$125000. If a third of the after-tax earnings were remitted as dividends, the deemed tax would be equal to 1/3*$250000=$83000.
