"A significant positive step toward improving the investment climate would be to further reduce tax uncertainty for multinational companies and institutional investors in India," Nisha Desai Biswal, the president of the US-India Business Council (USIBC), said in a memorandum submitted to Mr Jaitley.
Noting that in today's economic environment, scarce capital is allocated to markets offering optimal returns, Ms Biswal said global businesses allocate investments where post-tax returns for a given risk profile are highest.
When tax costs are uncertain, particularly in a foreign country, investors normally provide for them on a most conservative basis, she said.
"Therefore, tax uncertainty results in an increase of risk when investing in any given project drives investors to either withhold investments or require a higher rate of return to account for this risk, thus raising the cost of capital in the uncertain market," said Ms Biswal, who was the Obama administration's point person for South and Central Asia.
Welcoming Prime Minister Narendra Modi's plans to "transform" India's economy and his efforts to promote India as a global investment destination, the USIBC said that for India to be successful in attracting international investors, it needs to create a more stable and predictable fiscal regime and address retrospective taxation and legacy cases that remain open.
"USIBC members believe that unless resolved, the lack of clarity in the government's approach to taxation risk will undermine progress in other areas of the economy and will continue to damage India's reputation among investors," said the memorandum running into 39 pages.
Describing it as a major concern for international investors, including USIBC members, Ms Biswal said by rescinding the historical retrospective tax legislation, India would have an opportunity to proceed to a satisfactory resolution of legacy cases which would be beneficial to both India and the companies involved.
As indicated by the high-profile nature surrounding recent cross-border tax rulings, one of the primary frustrations of foreign multinational companies investing in India is an often inconsistent transfer pricing regime and a lack of a predictable, efficient dispute resolution mechanism, the USIBC rued.
USIBC said it believes that India must ensure that transfer pricing principles are applied in a fair and consistent manner for all taxpayers, as well as allow a reasonable method for determining transfer pricing standards that support fees on services performed in India for non-Indian affiliated entities and match the nature of the company's services performed.
"To facilitate cross-border trade and investment without the barrier of double taxation, the Government of India and the US Government should reaffirm the shared commitment to improving tax dispute resolution," the memorandum said.
