In 2017 President Trump cut the Corporate Tax rate

Tax reforms like these encourage the economy on the demand side (by increasing aggregate demand) as well as on the supply side (by raising investments and increasing production). The supply side factors raised the argument for further tax cuts, implying that such kind of tax reduction will lead to more tax revenues. A fall in tax rate implies increased production, high employment and greater income. More income means more tax revenues.

There were a few unintended consequences of these tax reforms as they did not help much in increasing the tax revenues during his tenue. The government expenditure continued to increase at the same time. The amalgamation of an increase in government expenditure and reduction in taxes led to a deficit. Thus, rather than lowering taxes, they should reduce government spending. Also as expected, government debt did not reduce but increased significantly.

Does that help?

Despite enactment of the 2017 Tax Cuts and Jobs Act, which reduced incentives, current rules still encourage US multinational firms to earn and report profits in low-tax foreign countries, enable both US- and foreign-based firms to shift profits earned in the United States to other countries, and encourage companies to incorporate in foreign jurisdictions.

INCENTIVES TO EARN AND REPORT PROFITS IN LOW-TAX COUNTRIES

Multinational corporations typically operate overseas through foreign subsidiaries that are mostly taxed as independent corporate entities. This separate entity system gives multinationals incentives to shift reported profits to their affiliates in low-tax jurisdictions by underpricing sales to them and overpricing purchases from them.

For tax-reporting purposes, most governments require firms to use an “arm’s length” standard, setting prices for transactions within the corporate group (“transfer prices”) equal to the prices that would prevail if the transactions were between independent entities. Yet ample room remains for firms to manipulate transfer prices, especially for intangible assets such as patents that are unique to the firm and for which there is no easily established market price.

Leading multinationals often shift the ownership of their intangibles, which generate a large share of their worldwide profits, to affiliates in very low tax jurisdictions, such as Ireland and Singapore. Through complex transactions, multinationals can then shift reported profits from these jurisdictions to countries with no corporate income tax, such as Bermuda and the Cayman Islands. Typically, multinationals generate very little real economic activity—as measured by output, employment, sales, or investments in plant and equipment—in tax-free jurisdictions.

Before the 2017 Tax Cuts and Jobs Act (TCJA), US multinationals booked a disproportionate share of their profits in low-tax locations. In 2015, US multinationals reported over one-third of their overseas profits in three low-tax countries: the Netherlands, Ireland, and Bermuda . The top 10 foreign locations of their profits, including other low-tax countries such as Luxembourg, Switzerland, Singapore, the UK Caribbean Islands, and the United Kingdom, accounted for almost three-fourths of their non-US profits.

Despite evidence that firms shift the location of real economic activity in response to tax-rate differences among countries, a substantial share of US multinationals’ real activity remains in high-tax countries. These are mostly large economies with close ties to the United States. Before TCJA, the effective corporate tax rates on new investments in such countries was slightly lower than the US rate.

The TCJA substantially reduced, but did not eliminate, the incentive for US corporations to shift profits to tax havens. It did this by introducing a new minimum tax on Global Low Tax Intangible Income (GILTI) at 10.5 percent beginning in 2018, increasing to 13.125 percent in 2026. The GILTI rate remains below the 21 percent US corporate rate and the rate in other countries in the G7 (which ranges from 19 percent in the United Kingdom to 34 percent in France). TCJA also reduced incentives for US companies to hold intangible assets in low-tax foreign countries by providing a special rate (13.125 percent beginning in 2018 and 16.406 percent beginning in 2026) for export income from intangible assets held in the United States (Foreign Derived Intangible Income).

How TCJA affects the location of reported profits and real activities of US multinationals overseas will not be known for several years. However, we can expect in a few years that US companies will report substantially lower shares of their profits in low-tax countries with little economic activity.

INCENTIVES TO INCORPORATE OVERSEAS

The United States bases its definition of corporate residence on place of incorporation. This definition need not be consistent with where a company’s production and employment is located, where its sales take place, where its shareholders reside, or even where its top managers live.

For some firms, the tax benefits of foreign residence, combined with the lack of economic substance to the residence definition, have led them to shift the formal incorporation of their parent companies overseas. This type of transaction (“inversion”) can often be accomplished without changing the location of any real business activities.

Over the years, Congress has enacted rules to limit inversions. A company can still “redomicile,” though, by merging with a foreign-based company under certain conditions, including that the original foreign company contribute at least 20 percent of the shares of the new merged company if other conditions are not met. The TCJA added new provisions to penalize new inversions. In exchange for TCJA eliminating the tax on repatriated dividends, it imposes a 35 percent transition tax on overseas assets that newly inverted firms held before TCJA. Other US companies with foreign assets pay a comparable transition tax at 15.5 percent for cash and 8 percent for other assets. TCJA also introduced other penalties on newly inverted firms, including a provision that makes dividends to shareholders taxable as ordinary income instead of at the preferred rates generally applied to qualified dividends and long-term capital gains.

The current US system still provides benefits for some multinational corporations to establish their parent company’s residence outside the United States, although this incentive is smaller at the new reduced corporate tax rate. The United States now imposes GILTI on the intangible profits US-resident corporations earn in low-tax countries, while our major trading partners have so-called territorial systems that exempt active foreign-source profits. In addition, rules for US controlled foreign corporations limit US-based multinationals’ ability to use debt-equity swaps and other earnings-stripping techniques to shift reported income out of the United States. But the United States is unable to apply its controlled foreign corporation rules to foreign-resident multinationals.

The US Department of the Treasury (2016), however, has recently issued new regulations to deter earnings stripping through interest payments to foreign-related parties and the Base Erosion and Anti-abuse Tax (BEAT), enacted as part of TCJA, imposes a minimum tax on a base that disallows deductions for certain payments, including interest, to foreign-related parties. Both Treasury regulations and BEAT aim to limit foreign-resident multinationals’ ability to shift profits out of their US affiliates, although BEAT also affects US-resident companies.

A corporation’s formal residence may be losing significance in an increasingly global economy where capital flows freely and a firm’s research and development, production, and sales are often spread worldwide. The location of a multinational firm’s investment, jobs, research and development, and tax revenue matter more than the site of its parent company. Corporate residence, however, does have some effect on US tax revenues and arguably may matter for research and development and other high-value activities often associated with a company’s headquarters.
