Inversions are major international tax issues for both tax administrations and multinational enterprises (MNEs). Research done by international consulting firms, government agencies, and independent researchers has reflected countries’ significant tax revenue losses and tax base erosion due to inversions, as MNEs shift profit from high-tax to low-tax countries to minimize their global effective tax rate. These inversions are relevant for both tax administrators and taxpayers since they determine the Withholding tax liabilities and reporting of income of associated enterprises in different tax jurisdictions.
MNEs use inversions to shift their worldwide profit and consequent tax burden from their high-tax home base to low or no-tax countries (Markle & Shackelford, 2012). Clausing, Miller, and Mintz (2020) indicated that profit shifting as reflected in 2017 country by country reporting (CBCR) showed accumulated earnings offshore of $4.4 trillion, with $2.8 trillion located in Bermuda, the Caymans, Ireland, Jersey, Luxembourg, Netherlands, Puerto Rico, Singapore, and Switzerland.
The general problem is that MNEs shift profit and taxes from the United States using existing tax legislation. The specific problem is despite the tax rate reduction in 2017 legislation, shifting of profit and taxes is still occurring by MNEs. The share of income in tax havens in 2019 (61% of after-tax income; 1.5% of GDP) is identical to the average of the years prior to the law (2013–2017) (Clausing, Miller, and Mintz (2020). This problem has negatively impacted social and economic programs because of reduced collection of tax revenues. Docksai (2013) reflected that governments should be active in investment that contributes to economic growth and job creation as well as facilitate health care, education, infrastructure projects, and social welfare programs with the primary source of finance for the investment being tax revenues. A possible cause of this problem is MNEs’ strategy of complying with the legislation. This study, in which I investigated differences in reporting of WHT, before and after the 2017 U.S. tax rate reduction legislation, solves the problem by identifying either MNEs’ reversal of inversions or engagement in tax management. Therefore, this study informs both economic and strategic management theories that propose changes in tax rate legislation as proposed by economic theory as well as the management strategy of foreign controlled corporations (FCCs) in determining the overall profit of the multinational enterprise as they engage in strategies for allocating their global tax liabilities, as proposed by economic theory and strategic management theory.
The purpose of this causal-comparative study was to compare the reporting of withholding tax (WHT), to investigate differences in total U.S.-source income as well as to investigate differences in the components of U.S.-source income including dividends, interest, and rent/royalties in respect of WHT collections, before and after the 2017 U.S. corporate income tax (CIT) rate reduction.
The research questions and hypotheses guiding my research were as follows:
Research Question 1(RQ1): What is the difference in the reporting of WHT before and after the tax rate reduction in 2017 legislation?
Null Hypothesis (H01): There is no difference in the reporting of WHT before the tax rate change in the legislation when compared to after the update.
H01: X1 – X2 = 0
Alternative Hypothesis (Ha1): There is a difference in the reporting of WHT before the tax rate change in the legislation when compared to after the update.
Ha1:X1 – X2 ≠ 0
I used a Wilcoxon’s signed rank test to compare the data of one group of companies, before and after the tax rate change in the legislation, for testing this first hypothesis.
Research Question 2 (RQ2): What is the difference in the reporting of total U.S.-source income in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction?
Null Hypothesis (H02): There is no difference in the reporting of Total U.S.-Source Income in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction.
H02: X1 – X2 = 0
Alternative Hypothesis (Ha2): There is a difference in the reporting of Total U.S.-Source Income in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction.
Ha2:X1 – X2 ≠ 0
I used a Wilcoxon’s signed rank test to compare the data of one group of companies, before and after the tax rate change in the legislation, for testing this second hypothesis.
Research Question 3 (RQ3): What is the difference in the reporting of the dividends’ component of U.S.-Source Income in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction?
Null Hypothesis (H03): There is no difference in the reporting of the dividends’ component of U.S.-Source Income in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction.
H03: X1 – X2 = 0
Alternative Hypothesis (Ha3): There is a difference in the reporting the dividends’ component of U.S.-Source Income including in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction.
Ha3:X1 – X2 ≠ 0
Research Question 4 (RQ4): What is the difference in the reporting of the interest component of U.S.-Source income in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction?
Null Hypothesis (H04): There is no difference in the reporting of the interest component of U.S.-Source income in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction.
H04: X1 – X2 = 0
Alternative Hypothesis (Ha4): There is a difference in the reporting the interest component of U.S.-Source income including in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction.
Ha4:X1 – X2 ≠ 0
Research Question 5 (RQ5): What is the difference in the reporting of the rent/royalties component of U.S.-Source income in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction?
Null Hypothesis (H05): There is no difference in the reporting of the rent/royalties component of U.S.-Source income in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction.
H05: X1 – X2 = 0
Alternative Hypothesis (Ha5): There is a difference in the reporting the rent/royalties component of U.S.-Source income including in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction.
Ha5:X1 – X2 ≠ 0
To the best of my knowledge, this study was the first to measure differences on MNEs reporting of WHT and to investigate differences in the Total U.S.-Source Income as well as the components of U.S.-Source Income including dividends, interest, and rent/royalties in respect of WHT collections, before and after the 2017 U.S. CIT tax rate reduction to the U.S. Treasury using a Wilcoxon’s signed rank test.
Inversions facilitate shifting of MNEs worldwide profit and consequent tax burden from their high-tax home base to low or no-tax countries. An inversion is a transaction in which a US-based multinational company merges with a smaller foreign company and then establishes its residence in the foreign company’s country, significantly reducing its taxes without changing the location of any real business activities (International Monetary Fund (2019).
The theories that I tested for my study are economic theory and strategic management theory. Economic theory proposes that tax rates due to the status of legislation are relevant in determining the overall profit of the firm sine the tax rates influence the reporting of WHT and profit. The other theory, strategic management theory indicates that management strategy is relevant in determining the overall profit of the multinational enterprise (MNEs) as they engage in strategies for allocating their global tax liabilities since the status of legislation establishes specific tax rates that influences the reporting of WHT and operating profit. These theories affect the operations of tax administrations and MNEs and present a view of inversions that can be used to explain, describe, predict, and control having specific tax legislation. Consequently, there was a need to assess the effect of tax rate change legislation on the reporting of WHT and operating profit in the United States, which is the subject of my research in ensuring compliance with tax legislation.
This study involved examining the effect of the status of tax rate legislation on the reporting of WHT and Total U.S.-Source Income as well as the components of U.S.-Source Income including dividends, interest, and rent/royalties. As such, I adopted a quantitative approach with the ex-post facto or causal-comparative research design for investigating differences pre- and post implementation. Since the IRS has already implemented the independent variable in the proposed study, this existing variable could not be manipulated; the casual comparative research design is the most suitable design for the study.
The purpose of this causal-comparative study was to compare the reporting of WHT and profit, before and after change in legislation. I used a Wilcoxon’s signed rank test to compare the data of one group of companies, before and after the updated tax rate legislation, for testing the hypotheses. Therefore, my study included analyzing existing data relating to the effect of the tax rate legislation on the reporting of WHT and U.S.-Source Income.
Several previous researchers have used the quantitative approach with the ex-post facto design. The United States General Accounting Office (1995) compiled a report in response to requests for data on the TP issues relating to tax compliance of FCCs and USCCs using tax data for 1990 and 1991. The Department of the Treasury (2007) report resulted from studies on earnings-stripping and transfer pricing. The earnings stripping study focused on comparing the profitability of FCCs to USCCs using data from income tax returns filed with the U.S. IRS (Department of the Treasury, 2007). Department of the Treasury’s second study focused on transfer pricing, using tax returns data, and included a review of Section 482 of the U.S. IRC. Additionally, the United States Government Accountability Office (GAO) (2008) accessed data from the IRS’s SOI database containing samples of tax returns for several years. Additionally, McDonald (2008) researched U.S. tax return data, using a regression model, in determining whether 12 operating profit shifting occurred with controlled foreign corporations through transfer pricing. McDonald’s study extended work done by Grubert (2003) in respect of using tax return data for determining operating profit shifting. Further, Avi-Yonah (2007) examined U.S. TP legislation in concluding that the United States should continue to apply the ALS in taxation for determining transaction values between related parties. The Joint Committee on Taxation report submitted to the House Committee on Ways and Means (2010) noted that this document dealt with business restructuring, legislation, case studies of U.S. MNEs, and the way the structure of these MNEs utilize the IRC in determining their U.S. tax liability. Additionally, Klassen, Lang, and Wolfson (1993) studied operating profit shifting by U.S. MNEs in response to global changes in tax rates using samples of both U.S. and non-U.S. based operations. The inquiry required performing regression analysis on existing data from financial statements extracted from Compustat for the period 1984–1990. Finally, Grubert (2012) extracted data from a sample of income tax files relating to U.S.-based MNEs including information contained in the tax return Form 1120 and Form 5470 that has financial statements’ data. Grubert (2012) used regression analysis on the data in concluding that U.S.-foreign tax rate differentials affected the location of the foreign portion of global profits for U.S.-based MNEs. Therefore, my research is consistent with previous studies that applied the ex-post facto research approach of examining existing data and noting the effect on profit reporting.
