Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded an income tax expense of $0.7 million and $80.9 million for the three months ended June 30, 2021 and 2020, respectively and an income tax expense of $1.2 million and $156.7 million for the six months ended June 30, 2021 and 2020, respectively. The 2021 income tax expense primarily related to an increase in valuation allowance for U.S deferred tax assets and to the Macau dividend tax agreement that provides for an annual payment of MOP 12.8 million (approximately $1.6 million) as complementary tax otherwise due by stockholders of Wynn Macau SA. The 2020 income tax expense primarily related to the increase in the valuation allowance for U.S. foreign tax credits. In March 2021, the Company received an extension of its Macau dividend tax agreement, providing for a payment of MOP 12.8 million (approximately $1.6 million) for 2021 and MOP 6.3 million (approximately $0.8 million) for the period ending June 26, 2022, the expiration date of the gaming concession agreement. The Company records valuation allowances on certain of its U.S. and foreign deferred tax assets. During the third quarter of 2020, the Company concluded it could no longer rely on forecasted future taxable income in assessing a valuation allowance on its deferred tax assets. This conclusion was reached due to cumulative operating losses incurred by the Company and tax legislation that reduced future sources of taxable income. As of June 30, 2021, the Company continues to rely solely on the reversal of net taxable temporary differences in assessing a need for a valuation allowance. In April 2020, Wynn Macau SA received an extension of the exemption from Macau’s 12% Complementary Tax on casino gaming profits earned from January 1, 2021 to June 26, 2022, the expiration date of the gaming concession agreement. For the three and six months ended June 30, 2021 and 2020, the Company did not have any casino gaming profits exempt from the Macau Complementary Tax. The Company's non-gaming profits remain subject to the Macau Complementary Tax and its casino winnings remain subject to the Macau special gaming tax and other levies in accordance with its concession agreement. In March 2021, the Financial Services Bureau concluded its review of the 2017 and 2018 Macau income tax returns of Palo with no changes.
