|Income Tax Disclosure [Abstract]
The Tax Cuts and Jobs Act of 2017 (the “New Tax Legislation”) was enacted on December 22, 2017, which significantly revised the U.S. corporate income tax code by, among other things, lowering federal corporate income tax rates, implementing a modified territorial tax system and imposing a repatriation tax on deemed repatriated cumulative earnings of foreign subsidiaries. The New Tax Legislation created, among other things, a new requirement that certain income earned by controlled foreign corporations (“CFCs”) must be included currently in the gross income of the CFCs’ U.S. shareholder. In addition, new taxes were imposed related to foreign income, including a tax on global intangible low-taxed income (“GILTI”) as well a limitation on the deduction for business interest expense, (“Section 163(j))".
GILTI is the excess of the shareholder’s net CFC tested income over the net deemed tangible income. The Section 163(j) limitation does not allow the amount of deductible interest to exceed the sum of the taxpayer's business interest income, 30% of the taxpayer’s adjusted taxable income, and the taxpayer’s floor plan financing interest expense for the year. We have included in our calculation of our effective tax rate the estimated impact of GILTI and Section 163(j).
In the quarter ended December 30, 2017, when the New Tax Legislation was enacted, we made reasonable estimates of the effects on our existing deferred tax balances and the transition tax, recording $10.6 million of tax expense based on an estimate of our total earnings and profits (E&P) from our foreign subsidiaries which were previously deferred from U.S. taxes. During the quarter ended September 29, 2018, we increased the provisional amount by $0.1 million based on our E&P study resulting in $10.7 million recorded in our 2018 fiscal year. The transition tax will be paid over eight years. The transitional tax was finalized during the first quarter of fiscal year 2019 and is no longer considered provisional.
Our effective income tax rate on operations for the six-month period ended March 30, 2019, was a benefit of 60.5% driven from the discrete tax benefit from the vesting of stock awards. For the six-month period ended March 31, 2018, our effective income tax rate, excluding the $10.6 million provision related to The New Tax Legislation, was a benefit of 9.4%. Our effective income tax rate on operations for the fiscal year ended September 29, 2018, excluding the $10.7 million provision related to The New Tax Legislation, was a benefit of 1.7%.
We intend to reinvest all of our unremitted earnings of our foreign subsidiaries and therefore, outside of the transition tax mentioned previously, we have provided no provision for income taxes which may result from withholding taxes and/or other outside basis differences. We believe that the determination of such income taxes is impracticable.
We benefit from having income in foreign jurisdictions that are either exempt from income taxes or have tax rates that are lower than those in the United States. Based on our current projected pre-tax income and the anticipated amount of U.S. taxable income compared to profits in the offshore taxable and tax-free jurisdictions in which we operate, our estimated annual income tax rate for the fiscal year ending September 28, 2019, is currently expected to be approximately 16%-18%. However, changes in the mix of U.S. taxable income compared to profits in tax-free or lower-tax jurisdictions can have a significant impact on our overall effective tax rate. In addition, the final impact of the New Tax Legislation may differ from our estimates, possibly materially, due to, among other things, changes in interpretations, additional regulatory guidance that may be issued, additional information that may become available to us, and actions we may take as a result of the New Tax Legislation.
We file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. Tax years 2014, 2015, and 2016, according to statute and with few exceptions, remain open to examination by various federal, state, local and foreign jurisdictions.
