U.S. companies have moved cautiously in repatriating stockpiled overseas profits in response to last year’s tax-law change, despite the Trump administration’s assertions that trillions of dollars would return home quickly and supercharge the domestic economy.

The tax-law rewrite ended the practice of taxing U.S. companies when they repatriated foreign profits. Companies, which often complained that profits were trapped abroad, held them in foreign subsidiaries, piling up global earnings to avoid additional taxes. The new law imposed a one-time tax on those old profits, removed federal taxes on subsequent repatriations and made future foreign profits generally free from U.S. taxes.
