Corporate Income Taxes

According to the Washington Times, Sen. Bernie Sanders of Vermont is castigating American companies in international business from not paying corporate US taxes. Here's the text from Bernie Sanders:
"One out of four American corporations already pay no federal income tax. Now, more and more of them have come up with a new scheme to dodge U.S. taxes by moving their headquarters overseas. Bernie filed legislation to ban those businesses from receiving U.S. government contracts. “I have a message for these corporate deserters: You can't be an American company only when you want corporate welfare from American taxpayers or you want lucrative contracts from the federal government.” The giant drug maker AbbVie made no bones about the fact that ducking U.S. taxes is why it hopes to take over its European rival. Walgreen’s, the giant drugstore chain launched at a Chicago storefront, may move its corporate headquarters to Switzerland to avoid U.S. taxes. They are part of a growing corporate trend. Bernie had a word for it. “It’s treason,” he said."
Now let's look at the real facts.
US-based international corporations generally have subsidiaries or joint ventures overseas. When those subsidiaries or joint ventures make a profit, US-based corporations have an option to either return their profits to the United States or keep it overseas for further investment. If the profit is kept overseas it is not taxable by the IRS, but those profits tend to accumulate overseas and investment opportunities may decline. In addition, stockholders of the US parent may want dividends, which pressures the parent companies to return the foreign profits to the US. On return of the foreign profits to the US, the IRS immediately slaps on a corporate income Tax. The net result is that he US-based international corporation may delay its payment of income tax, but eventually the income tax must be paid as the profits are repatriated to the US.
We now see another phase of evolution in corporate finance. That is, US based corporations do not have to continue as US corporations. They have the option of converting to a foreign-based corporation. The advantage of conversion is a lower income tax rate in the country where the corporation is newly based. To me, this makes good business sense. Why pay more taxes than necessary? As a stockholder, I am interested in dividends. If the foreign country takes less tax than the US, there is more profit left for my dividend. My corporation is to me a money machine. I don't care whether it's based in the US or some foreign country. Since Sen. Sanders is concerned about that, let him reduce the US corporate tax rate to the lower equivalents of foreign countries.
There is another aspect which is even more egregious. There should be no US corporate tax. Companies based in the US have their profits taxed based on profits generated in the US and also repatriated from abroad. When that tax is subtracted from the profit, there is less less for my dividend. In addition, as a stockholder, when I file my Form 1040, I must pay a second tax on my dividends. In other words, the US government is first hitting my corporation in taxing its profits and then again taxes me on whatever profit is left and paid as dividend. This is clearly double taxation, which means tax it once and then tax it again. If you leave it up to Congress which has an insatiable need for money, you can be sure it is looking for ways to tax it a third time and a fourth time, etc.
